CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of priority under 35 U.S.C. § 119 of U.S. Provisional Application Serial No. 63/014,401 filed on April 23, 2020, the content of which is relied upon and incorporated herein by reference in its entirety.

BACKGROUND

[0002] The disclosure relates to glass articles and methods for forming same, and more particularly to vehicle interior systems including a glass article with carrier providing low shape deviation and high mechanical reliability.

[0003] Vehicle interiors include curved surfaces and can incorporate displays in such curved surfaces. The materials used to form such curved surfaces are typically limited to polymers, which do not exhibit the durability and optical performance as glass. As such, curved glass substrates are desirable, especially when used as covers for displays. Existing methods of forming such curved glass substrates, such as thermal forming, have drawbacks including high cost, optical distortion, and surface marking. Accordingly, Applicant has identified a need for vehicle interior systems that can incorporate a curved glass substrate in a cost- effective manner and without problems typically associated with glass thermal forming processes.

SUMMARY

The curved glass article includes a glass sheet having a first major surface and a second major surface opposite to the first major surface. The glass sheet is bent into a curved configuration defining a curved region disposed between a first flat section and a second flat section. The curved region has a radius of curvature of at least 250 mm. The curved glass article also includes a carrier adhered to the second major surface of the glass sheet and configured to maintain the glass sheet in the curved configuration. The carrier includes a first longitudinal strip, a second longitudinal strip, a first lateral strip, and a second lateral strip. The first longitudinal strip is spaced apart from the second longitudinal strip, and the first longitudinal strip and the second longitudinal strip define the radius of curvature of the curved region.

DETAILED DESCRIPTION

[0024] Reference will now be made in detail to various embodiments, examples of which are illustrated in the accompanying drawings. In general, the various embodiments pertain to vehicle interior systems having curved glass surfaces. In the embodiments discussed herein, the curved glass surfaces comprise a glass sheet bonded to a carrier that holds the glass in its curved shape. Further, the carrier is configured to be mounted to a frame of an automotive interior system. As will be described herein, the carrier provides a minimal non-display region (referred to herein as a “bezel”) that can be as small as 1 mm on the top and bottom sides and as small as 8 mm on the lateral sides (for a glass article having a 0.7 mm thick glass sheet, rectangular carrier, and radius of curvature of 250 mm), leaving a large majority of the glass surface available for viewing a rear-mounted display. Additionally, the shape and width of the carrier are configured to provide mechanical reliability against cold-forming stresses and thermal stresses associated with typical operating environments. Various embodiments of the carrier and configurations for mounting the carrier to a vehicle frame are disclosed herein. These embodiments are provided by way of illustration and not by way of limitation.

[0025] In general, a vehicle interior system may include a variety of different curved surfaces that are designed to be transparent, such as curved display surfaces and curved non-display glass covers. Forming curved vehicle surfaces from a glass material provide a number of advantages compared to the typical curved plastic panels that are conventionally found in vehicle interiors. For example, glass is typically considered to provide enhanced functionality and user experience in many curved cover material applications, such as display applications and touch screen applications, compared to plastic cover materials.

[0026] FIG. 1 shows an exemplary vehicle interior 1000 that includes three different embodiments of a vehicle interior system 100, 200, 300. Vehicle interior system 100 includes a frame, shown as center console base 110, with a curved surface 120 including an optically bonded display 130. Vehicle interior system 200 includes a frame, shown as dashboard base 210, with a curved surface 220 including an optically bonded display 230.

The dashboard base 210 typically includes an instrument panel 215 which may also include an optically bonded display. Vehicle interior system 300 includes a frame, shown as steering wheel base 310, with a curved surface 320 and an optically bonded display 330. In one or more embodiments, the vehicle interior system includes a frame that is an arm rest, a pillar, a seat back, a floor board, a headrest, a door panel, or any portion of the interior of a vehicle that includes a curved surface. In other embodiments, the frame is a portion of a housing for a free-standing display (i.e., a display that is not permanently connected to a portion of the vehicle). In embodiments, the optically bonded display 130, 230, 330 is at least one of a light emitting diode (LED) display, an organic LED (OLED) display, a liquid crystal display (LCD), or plasma display

[0027] The embodiments of the glass article described herein can be used in each of vehicle interior systems 100, 200 and 300. Further, the glass articles discussed herein may be used as curved cover glasses for any of the display embodiments discussed herein, including for use in vehicle interior systems 100, 200 and/or 300. Further, in various embodiments, various non-display components of vehicle interior systems 100, 200 and 300 may be formed from the glass articles discussed herein. In some such embodiments, the glass articles discussed herein may be used as the non-display cover surface for the dashboard, center console, door panel, etc. In such embodiments, glass material may be selected based on its weight, aesthetic appearance, etc. and may be provided with a coating (e.g., an ink or pigment coating) with a pattern (e.g., a brushed metal appearance, a wood grain appearance, a leather appearance, a colored appearance, etc.) to visually match the glass components with adjacent non-glass components. In specific embodiments, such ink or pigment coating may have a transparency level that provides for deadfront or color matching functionality. [0028] In embodiments, the curved surfaces 120, 220, 320 are generally either V-shaped as shown in FIGS. 2A and 2B or C-shaped as shown in FIGS. 4A-4B; although other shapes are possible. Referring first to FIG. 2 A, a side view of an embodiment of a V-shaped article 10 is shown. The V-shaped glass article 10 includes a glass sheet 12. The glass sheet 12 has a first major surface 14 and a second major surface 16. In a vehicle, the first major surface 14 faces the occupants of the vehicle, and the second major surface 16 is the rear surface of the V-shaped glass article 10 to which a display (e.g., an LED display, OLED display, LCD display, or a plasma display) may be mounted, e.g., using an optically clear adhesive. The second major surface 16 is opposite to the first major surface 14, and the first major surface 14 and the second major surface 16 define a thickness T of the glass sheet 12. The first major surface 14 and the second major surface 16 are joined by a minor surface 18.

[0029] As can be seen in FIG. 2A, the glass sheet 12 has a curved region 20 disposed between a first flat section 22a and a second flat section 22b. In embodiments, the curved region 20 has a radius of curvature R that is from 250 mm to a radius that is less than substantially flat or planar (e.g., 10 m). Further, as shown in FIG. 2A, the curved region 20 defines a concave curve, but in other embodiments, the curved region 20 is instead a convex curve. For the V-shaped article 10 of FIG. 2A, an adhesive 24 is applied on the second major surface 16 in the curved region 20. The adhesive 24 attaches a carrier 26 to the glass sheet 12. As can be seen in FIG. 2A, the carrier 26 extends over the entire curved region 20 and at least partially into the flat sections 22a, 22b. The portion of the carrier 26 extending into the flat sections 22a, 22b is shown between the dashed lines labeled “Flat area.” As will be discussed more fully below, Applicant has determined a carrier size and thickness designed to minimize the distance that the carrier 26 extends into the flat sections 22a, 22b while also maintaining shape deviation of the glass sheet 12 to within ± 0.3 mm.

[0030] In embodiments, the adhesive 24 comprises a pressure sensitive adhesive. Exemplary pressure sensitive adhesives suitable for use in the adhesive 24 include at least one of 3M™ VHB™ (available from 3M, St. Paul, MN) or tesa® (available from tesa SE, Norderstedt, Germany). In embodiments, the adhesive 24 comprises a liquid adhesive. Exemplary liquid adhesives include toughened epoxy, flexible epoxy, acrylics, silicones, urethanes, polyurethanes, and silane modified polymers. In specific embodiments, the liquid adhesive includes one or more toughened epoxies, such as EP21TDCHT-LO (available from Masterbond®, Hackensack, NJ), 3M™ Scotch-Weld™ Epoxy DP460 Off-White (available from 3M, St. Paul, MN). In other embodiments, the liquid adhesive includes one or more flexible epoxies, such as Masterbond EP21TDC-2LO (available from Masterbond®, Hackensack, NJ), 3M™ Scotch-Weld™ Epoxy 2216 B/A Gray (available from 3M, St. Paul, MN), and 3M™ Scotch-Weld™ Epoxy DP125. In still other embodiments, the liquid adhesive includes one or more acrylics, such as LORD® Adhesive 410/ Accelerator 19 w / LORD® AP 134 primer, LORD® Adhesive 852/LORD® Accelerator 25GB (both being available from LORD Corporation, Cary, NC), DELO PUR. SJ9356 (available from DELO Industrial Adhesives, Windach, Germany), Loctite® AA4800, Loctite® HF8000. TEROSON® MS 9399, and TEROSON® MS 647-2C (these latter four being available from Henkel AG & Co. KGaA, Dusseldorf, Germany), among others. In yet other embodiments, the liquid adhesive includes one or more urethanes, such as 3M™ Scotch-Weld™ Urethane DP640 Brown and 3M™ Scotch-Weld™ Urethane DP604, and in still further embodiments, the liquid adhesive includes one or more silicones, such as Dow Corning® 995 (available from Dow Coming Corporation, Midland, MI).

[0031] Further, in embodiments, a primer can be applied to prepare the surfaces of the glass sheet 12 and carrier 26 for better adhesion. Additionally or instead of applying the primer, carrier 26 may be roughened, in embodiments, to provide better adhesion between the adhesive 24 and the carrier 26. Further, in embodiments, an ink primer may be used in addition to or instead of the primer for metal and glass surfaces. The ink primer helps provide better adhesion between the adhesive 24 and ink covered surfaces (e.g., the pigment design mentioned above for deadfronting applications). An example of a primer is 3M™ Scotch-Weld™ Metal Primer 3901 (available from 3M, St. Paul, MN); other commercially available primers are also suitable for use in the present disclosure and can be selected based on surfaces involved in the bonding and on the adhesive used to create the bond.

[0032] Via the adhesive 24 and a cold-forming process (as described below), the carrier 26 holds the glass sheet 12 in the curved shaped. The carrier 26 is also configured to be attached to a frame of a vehicle interior system, such as the vehicle interior systems 100, 200, 300 of FIG. 1. As shown in FIG. 2A, the carrier 26 has a height H corresponding to the dimension of the carrier 26 normal to the glass sheet 12. In embodiments, the height H is from 5 mm to 20 mm, more particularly from 8 mm to 12 mm, and in particular, about 10 mm.

[0033] In embodiments, one or more displays 25 are mounted to the second major surface 16 of the glass sheet 12. As mentioned above, the display 25 may, for example, be an LED, OLED, LCD, or plasma display. Further, in embodiments, the display 25 is provided with touch functionality. In embodiments, the display 25 is adhered to the second major surface 16 of the glass sheet 12 using an optically clear adhesive 27.

[0034] FIG. 2B shows the rear surface, i.e., the second major surface 16, of the V-shaped glass article 10. In embodiments, the carrier 26 defines a closed or substantially closed shape. For example, as shown in FIG. 2B, the carrier 26 is defines a closed quadrilateral shape having a first longitudinal strip 28, a second longitudinal strip 30, a first lateral strip 32, and a second lateral strip 34. “Longitudinal” as used herein refers to the longest side of the glass sheet 12 and the side opposite to the longest side. In embodiments, the glass sheet 12 is cold-bent along its longitudinal sides. Thus, for the rectangular glass sheet 12 shown in FIG. 2B in which opposite sides have the same length, the longitudinal strips 28, 30 are the strips proximate and extending substantially parallel to both of the longest sides of the glass sheet 12. “Lateral” as used herein refers to the strips 32, 34 of the carrier 26 extending between the longitudinal strips 28, 30. Additionally, in embodiments, the lateral strips 32, 34 extend perpendicular to the curvature of the cold-bent glass sheet 12. In embodiments, the lateral strips 32, 24 connect the longitudinal strips 28, 30 to define a closed shape, and in other embodiments, the lateral strips 32, 34 do not connect the longitudinal strips 28, 30 but still define a substantially closed shape. “Substantially closed shape” as used herein means that the lateral strips 32, 34 are spaced no more than 10 mm, particularly no more than 5 mm, apart (on one or both ends) from the longitudinal strips 28, 30. Returning to the embodiment depicted in FIG. 2B, the strips 28, 30, 32, 34 define a rectangular shape for the carrier 26 in which the first longitudinal strip 28 is substantially parallel to and spatially disposed from the second longitudinal strip 30 and the first lateral strip 32 is substantially parallel to and spatially disposed from the second lateral strip 34.

[0035] While the embodiment depicted in FIGS. 2 A and 2B includes a glass sheet 12 defining a quadrilateral perimeter, the shape of the glass sheet 12 is not limited to such. In other embodiments, the glass sheet 12 may have a perimeter including curved sides, straight sides, or both curved and straight sides. In any such embodiments, the carrier 26 defines a closed or substantially closed shape across the curved region 20 of the glass article 10 and into the flat sections 22a, 22b.

[0036] As will be discussed more fully below, Applicant has found that the four strips provided in a closed or substantially closed shape are the minimum necessary to maintain a shape deviation of within ±0.3 mm in the curved region 20 of the glass sheet for a radius of curvature as low as 250 mm. As shown and discussed in relation to other embodiments, additional longitudinal or lateral strips may be provided to provide further support for the glass sheet 12 and to further reduce the shape deviation.

[0037] Besides the number of strips 28, 30, 32, 34, the thickness and location of the strips are also considerations in the design of the carrier 26, especially for the purposes of assuring reliability of the part in operation. In particular, the cold-bent glass article 10 will exert stress on the adhesive 24 based on the resiliency of the glass sheet 12, which will make the glass sheet 12 want to spring back to the planar configuration. Additionally, stress on the adhesive 24 arises from the different thermal expansions of the glass sheet 12 and carrier 26 such that, when exposed to temperature extremes, the carrier 26 tends to expand or contract more than the glass sheet 12, stressing the adhesive 24. Therefore, in order to provide reliable bonding between the glass sheet 12 and the carrier 26, the carrier 26 needs to have a sufficient surface area bonded to the glass sheet 12 in specific areas.

[0038] To that end and as mentioned above, the carrier 26 extends at least partially into the flat sections 22a, 22b of the glass sheet 12 such that the longitudinal strips 28, 30 extend across the curved region 20 and into the flat sections 22a, 22b. In embodiments, the longitudinal strips 28, 30 extend 10 mm or less into each of the flat sections 22a, 22b. In other embodiments, the longitudinal strips 28, 30 extend 8 mm or less into the flat sections 22a, 22b, and in still other embodiments, the longitudinal strips 28, 30 extend 5 mm or less, in particular about 4 mm, into the flat sections 22a, 22b. Additionally, in embodiments, the longitudinal strips 28, 30 have a width Wiong of 2 mm or less, in particular, 1 mm or less, to provide a large display area.

[0039] In embodiments, the lateral strips 32, 34 are positioned at the ends of the longitudinal strips 28, 30. In embodiments, the lateral strips 32, 34 have a width Wiat that extends from the edge of the longitudinal strips 28, 30 across the boundary between the flat section 22a or 22b and the curved region 20. In embodiments, the lateral strips 32, 34 extend 10 mm or less into the curved region 20. In embodiments, the lateral strips 32, 34 extend 8 mm or less into the curved region 20, and in still other embodiments, the lateral strips 32, 34 extend 5 mm or less, in particular about 4 mm, into the curved region 20. Thus, in embodiments, the lateral strips 32, 34 have a width Wiat of 20 mm or less, 16 mm or less, or 10 mm or less, in particular about 8 mm.

[0040] In other embodiments, a plurality of lateral strips 32, 34 may be provided in which each strip 32, 34 has a width Wia _t of 2 mm or less, in particular, 1 mm or less. Such an embodiment is depicted in FIG. 3. As can be seen there, each end of the longitudinal strips 28, 30 includes a lateral strip 32a, 34a at each end and another lateral strip 32b, 34b substantially parallel to and spatially disposed from the lateral strips 32a, 32b and located proximate to the boundary between the curved region 20 and the flat sections 22a, 22b.

[0041] FIG. 4A depicts an embodiment of a C-shaped glass article 40. The C-shaped glass article 40 also includes a glass sheet 12. As with the V-shaped glass article 10 of FIGS. 2A and 2B, the glass sheet 12 of the C-shaped glass article 40 of FIG. 4 A has a first major surface 14 and a second major surface 16 defining a thickness T and being joined by a minor surface 18. The C-shaped glass article 40 also has a curved region 20 and flat sections 22a, 22b. As compared to the V-shaped glass article 10, the C-shaped glass article 40 has a much larger curved region 20 and much smaller flat sections 22a, 22b. As can be seen in FIG. 4 A, the carrier 26 is attached to the second major surface 16 with the adhesive 24. Because the curved region 20 is much larger than in the previously discussed embodiment, the longitudinal strips 28, 30 of the carrier 26 extend along substantially the entirety of each longitudinal side as shown in FIG. 4B.

[0042] Having described the structure of the glass articles 10, 40, various configurations of the glass articles 10, 40 were investigated experimentally and through simulation. FIGS. 5A- 5D depict various configurations of carriers 26 for V-shaped glass articles 10. FIG. 5 A depicts an embodiment of a carrier having just two longitudinal strips. FIG. 5B depicts an embodiment of a carrier 26 according to the present disclosure having a rectangular shape with two longitudinal strips 28, 30 and two lateral strips 32, 34. FIG. 5C depicts an embodiment of a carrier 26 according to the present disclosure that is substantially similar to the carrier of FIG. 5B except that the carrier 26 of FIG. 5C has a third longitudinal strip 36 disposed about halfway between the first longitudinal strip 28 and the second longitudinal strip 30. FIG. 5D depicts an embodiment of a carrier 26 according to the present disclosure that is substantially similar to the carrier 26 of FIG. 5C except that the carrier of FIG. 5D includes a third lateral strip 38 disposed about halfway between the first lateral strip 32 and the second lateral strip 34. The third lateral strip 38 intersects with and is substantially perpendicular to the third longitudinal strip 36.

[0043] FIG. 6 A depicts the carrier of FIG. 5 A as attached to the second major surface of a glass sheet. FIGS. 6B-6D depict the carriers 26 of FIGS. 5B-5D, respectively, bonded to the second major surfaces 16 of the glass sheets 12. As can be seen in the comparative example of FIG. 6A and the embodiments according to the present disclosure of FIGS. 6B-6D, the second major surface 16 includes a display region 41 and a mask region 42. A display mounted to the second major surface 16 of the glass sheet 12 can be seen through the display region 41, and the mask region 42 covers the edges of the display, which may include wiring, circuit board, or mounting features for use of the display. In general, the carrier 26 is designed to allow for maximum usage of the display region 41 while still preventing large shape deviations and providing mechanical reliability.

[0044] In that regard, FIG. 7 depicts a table comparing the shape deviations for the comparative example of FIG. 6A and the embodiments of the present disclosure shown in FIGS. 6B and 6C. In FIG. 7, glass articles having a glass sheet of 0.7 mm thickness were considered in which the carrier had a uniform thickness of 1 mm and a height of 10 mm. The table of FIG. 7 includes both numerically modeled shape deviations as well as experimentally determined shape deviations. As will be appreciated from the table, the numerical modeling aligns closely with the experimentally determined results. Referring first to the comparative example including only two longitudinal strips, the strips extended 40 mm into the flat sections of the glass sheet, and a radius of curvature of about 320 mm was formed. As can be seen in the table, the comparative example exhibits significant shape deviation in the center of the glass sheet in the flat sections immediately adjacent to the curved region. In particular, the glass sheet exhibits a bowl-shaped deviation in which the depth of the bowl 0.45 mm or greater at its deepest depth.

[0045] When considering the examples according to the present disclosure, the shape deviation is never greater than 0.3 mm either according to the model or to the experimental data, in particular in the flat sections 22a, 22b. For the rectangular embodiment (FIG. 6B), the table of FIG. 7 considered longitudinal strips 28, 30 that extended 18 mm into the flat sections 22a, 22b and a radius of curvature of about 260 mm. The model exhibited essentially no shape deviation, and the experimental data exhibited only a small region that reached 0.3 mm. For the rectangular embodiment with the third longitudinal strip (FIG. 6C), the table of FIG. 7 considered longitudinal strips 28, 30, 36 that extended 18 mm into the flat sections 22a, 22b and a radius of curvature of about 250 mm. In this example, both the model and the experimental data exhibited essentially no shape deviation. Thus, the table of FIG. 7 demonstrates that the rectangular shape of the carrier 26 can prevent shape deviations of greater than 0.3 mm in the glass sheet 12, especially in the flat sections 22a, 22b.

[0046] To confirm the role that the shape of the carrier had on shape deviation, the extent to which the carrier extended into the flat sections was also investigated using numerical modeling. FIG. 8 depicts a table considering varying degrees to which the carrier extends into flat sections for the comparative example of FIG. 6 A and the exemplary embodiments of FIGS. 6B and 6C. Again, the numerical modeling considered glass sheets having a thickness of 0.7 mm. As can be seen, the comparative example was considered for extensions of 1 mm, 20 mm, and 40 mm into the flat sections. As can be seen, the shape deviation was greater as the longitudinal strips of the comparative example extended farther into the flat sections. In order to quantify the amount of the glass sheet that maintained a shape deviation of within ±0.3 mm, the metric of “in-spec area” was used, which refers to the percentage of surface area of the glass sheet that had a shape deviation of 0.3 mm or less. For the 40 mm extension, the comparative example exhibited an in-spec area of only 80%, and for the 20 mm extension, the in-spec area was only 82%. The greatest in-spec area for the comparative example was 92% for 1 mm extension into the flat sections. While somewhat counterintuitive that the decreasing extension into the flat area would increase the in-spec area, a glass article having longitudinal strips with no extension into the flat sections or not extending across the entire curved region would still not achieve 100% in-spec area as provided by the embodiments of the carrier 26 according to the present disclosure.

[0047] The table of FIG. 8 shows modeled data for the glass articles 10 having carriers 26 as shown in FIGS. 5B and 5C. For the rectangular carrier 26 of FIG. 5B, extensions of 1 mm,

10 mm, and 20 mm into the flat sections were considered. As can be seen in FIG. 8, the in- spec area was 100% for each of these examples. For the rectangular carrier 26 of FIG. 5C, extensions of 10 mm and 20 mm into the flat sections were considered. Again, the in-spec area was 100% for both of these examples as shown in FIG. 8. Thus, considering FIGS. 7 and 8, Applicant found that the shape of the carrier 26 was determinative of the shape deviation. Without wishing to be bound by theory, Applicant believes that the shape deviation is greater for the comparative example because the carrier only provides four points across the width of the glass sheet that are under 4-point bending whereas the additional lateral strips 32, 34 of the disclosed carrier 26 provide 4-point bending across the entire width of the glass sheet 12.

[0048] As mentioned above, the carrier 26 should not only provide minimal shape deviation for the glass sheet 12, but also, the bond between the carrier 26 and the glass sheet 12 should be mechanically reliable, especially against stresses induced by temperature changes. In order to provide mechanical reliability without sacrificing display area, Applicant investigated the width of the lateral strips 32, 34. FIG. 9 depicts a plot of the width of the lateral strips 32, 34 in the flat sections 22a, 22b (x-axis) versus the width of the lateral strips 32, 34 in the center region 20 (y-axis) for a glass article 10 having a 0.7 mm thick glass sheet 12 bent at a radius of curvature of 250 mm and experiencing thermal stresses associated with a temperature of 95 °C. For example, in the graph, a point of (4 mm, 2.5 mm) would correspond to a lateral strip 32, 34 with a width of 6.5 mm extending 4 mm from the boundary between the flat sections 22a, 22b and the curved region 20 into the flat sections 22a, 22b. Such a lateral strip 32, 34 would also extend 2.5 mm into the curved region 20. In FIG. 9, a variety of points for lateral strips 32, 34 extending into the flat sections 22a, 22b and/or into the curved region 20 were considered.

[0049] As can be seen for the embodiment depicted (0.7 mm thick glass sheet, rectangular carrier), Applicant has identified a minimum width for the lateral strips 32, 34 in order to provide mechanical reliability for a glass sheet bent at a radius of curvature of 250 mm. In particular, the width Wiat is 8 mm with 4 mm in the flat sections 22a, 22b and 4 mm in the curved region 20. A glass article 10 having a carrier 26 with lateral strips 32, 34 having such a width Wiat are able to withstand typical stresses associated with cold-forming and with temperature fluctuations, including with a safety factor. The boxed region of FIG. 9 in the “Mechanically Reliable” area provides good compromise between reliability and maximizing display area.

[0050] The minimum width Wia _t for the lateral strips 32, 24 will vary depending on other factors. For instance, for the same radius of curvature, a greater minimum width Wiat is expected be necessary for a relatively thicker glass sheet 12 than for a relatively thinner glass sheet 12, and for the same radius of curvature and glass thickness, a smaller minimum width Wiat is expected to be necessary if additional reinforcing features, such as a third longitudinal strip 36 or third lateral strip 38, are included in the carrier 26. Additionally, for a greater radius of curvature, the width Wiat may be smaller (e.g., all else being equal, the width Wiat may be less for a glass article 10 having a radius of curvature of 400 mm as opposed to 250 mm).

[0051] FIGS. 10A and 10B depict exemplary embodiments for forming a rectangular carrier 26. In embodiments of a rectangular carrier, the carrier 26 is formed from a single strip of material, bent into the rectangular configuration, and welded. The weld can be made with or without an overlap 44. FIG. 10A depicts an embodiment of the carrier 26 formed with an overlap 44 at the location of the weld. FIG. 10B depicts an embodiment of the carrier 26 formed without an overlap. In the embodiment of FIG. 10B, the ends of the strip are complementary and interlocking. The ends are interlocked and multiple welding points 46 are made to join the ends. In embodiments in which the carrier 26 is formed from a strip, the strips can be, e.g., laser cut, molded, or machined. In embodiments, additional longitudinal or lateral strips can be joined to the rectangular carrier 26 by spot welding the strips to the carrier after forming the rectangle. In other embodiments, carrier 26 can be made by die casting strips used to form the carrier 26. In such embodiments, additional longitudinal or lateral strips can be formed during die casting or welded to the rectangular carrier after die casting.

[0052] FIG. 11 depicts a further modification of the carrier 26 than can be made to lower stress in the adhesive 24. The modification involves chamfering at least the longitudinal strips 28, 30 of the carrier 26. Although, in other embodiments, all the strips 28, 30, 32, 34 may be chamfered. In the embodiment depicted, the longitudinal strips 28, 30 of the carrier 26 have a depending edge 48 that is formed or machined to provide an angled surface 50.

The angle a of the surface is from 20° to 60°, more particularly from 30° to 45°, and in particular about 34° (e.g., 33° to 35°). Further, the chamfering faces the interior of the carrier 26, i.e., the angled surfaces 50 of each longitudinal strip 28, 30 face each other.

[0053] Further, in embodiments, the carriers 26 of both the V-shaped glass article 10 and the C-shaped glass article 40 are made from a material having a CTE that matches the CTE of the glass sheet 12. The matching CTE reduces the thermal stress developed in the adhesive 24 as a result of thermal expansion differences between the glass sheet 12 and the carrier 26. In general, the glass sheet 12 will have a CTE of approximately 8(10 ⁶ )/°C. Thus, in embodiments, the carrier 26 is selected to have a CTE of between about 8(10 ⁶ )/°C and about 40(10 ⁶ )/°C, more particularly between about 8(10 ⁶ )/°C and about 22(10 ⁶ )/°C, even more particularly between about 8(10 ⁶ )/°C and about 15(10 ⁶ )/°C, and most particularly between about 8(10 ⁶ )/°C and about 15(10 ⁶ )/°C. In embodiments, the carrier 26 can be made of any material having a CTE between 8(10 ⁶ )/°C and 40(10 ⁶ )/°C when the adhesive is selected to have a bonding strength greater than the combined shear stress and bending stress. Thus, a variety of metal materials can be used, including steel (especially stainless steel, galvanized steel, and other corrosion-resistant steels), iron-nickel alloys, aluminum and its alloys, and magnesium and its alloys. Further, the carrier material can be a plastic or a composite material, such as a fiber-reinforced plastic composite material having, e.g., fibers (such as glass fibers, carbon fibers, aramid fibers, and/or graphite fibers) embedded in an epoxy resin (such as epoxy resin, polycarbonate, acrylic, polyester, polyetherketoneketone (PEKK), polycarbonate/acrylonitrile butadiene styrene (PC/ABS), polypropylene, and/or phenolic resin). In this way the carrier material and adhesive can be selected from a wide variety of materials, allowing for design and economic flexibility.

[0054] As mentioned briefly above, the glass sheet 12 is joined to the carrier 26 via cold forming methods. By cold-forming, it is meant that the curved region 20 is introduced to the glass sheet 12 at a temperature below the softening temperature of the glass. More particularly, cold-forming takes place at below 200 °C, below 100 °C, or even at room temperature. During cold forming, pressure is applied to the glass sheet 12 to bring the glass sheet 12 into conformity with the shape of the carrier 26. Pressure may be applied in a variety of different ways, such as vacuum pressure, a mechanical press, rollers, etc. In embodiments, pressure is maintained on the glass sheet 12 until the adhesive 24 cures (at least enough to prevent debonding of the glass sheet 12 from the carrier 26). Thereafter, the glass sheet 12 is bonded to the carrier 26, and the glass article 10, 40 may be shipped and/or installed as part of a vehicle interior system.

[0055] In the following paragraphs, various geometrical properties of the glass sheet 12 as well as compositions of the glass sheet are provided. Referring to FIG. 12, the glass sheet 12 has a thickness T1 that is substantially constant and is defined as a distance between the first major surface 14 and the second major surface 16. In various embodiments, T1 may refer to an average thickness or a maximum thickness of the glass sheet. In addition, the glass sheet 12 includes a width W1 defined as a first maximum dimension of one of the first or second major surfaces 14, 16 orthogonal to the thickness Tl, and a length LI defined as a second maximum dimension of one of the first or second major surfaces 14, 16 orthogonal to both the thickness and the width. In other embodiments, W1 and LI may be the average width and the average length of the glass sheet 12, respectively, and in other embodiments, W1 and LI may be the maximum width and the maximum length of the glass sheet 12, respectively (e.g., for glass sheets 14 having a variable width or length).

[0056] In various embodiments, thickness Tl is 2 mm or less and specifically is 0.3 mm to 1.1 mm. For example, thickness Tl may be in a range from about 0.1 mm to about 1.5 mm, from about 0.15 mm to about 1.5 mm, from about 0.2 mm to about 1.5 mm, from about 0.25 mm to about 1.5 mm, from about 0.3 mm to about 1.5 mm, from about 0.35 mm to about 1.5 mm, from about 0.4 mm to about 1.5 mm, from about 0.45 mm to about 1.5 mm, from about 0.5 mm to about 1.5 mm, from about 0.55 mm to about 1.5 mm, from about 0.6 mm to about 1.5 mm, from about 0.65 mm to about 1.5 mm, from about 0.7 mm to about 1.5 mm, from about 0.1 mm to about 1.4 mm, from about 0.1 mm to about 1.3 mm, from about 0.1 mm to about 1.2 mm, from about 0.1 mm to about 1.1 mm, from about 0.1 mm to about 1.05 mm, from about 0.1 mm to about 1 mm, from about 0.1 mm to about 0.95 mm, from about 0.1 mm to about 0.9 mm, from about 0.1 mm to about 0.85 mm, from about 0.1 mm to about 0.8 mm, from about 0.1 mm to about 0.75 mm, from about 0.1 mm to about 0.7 mm, from about 0.1 mm to about 0.65 mm, from about 0.1 mm to about 0.6 mm, from about 0.1 mm to about 0.55 mm, from about 0.1 mm to about 0.5 mm, from about 0.1 mm to about 0.4 mm, or from about 0.3 mm to about 0.7 mm. In other embodiments, the T1 falls within any one of the exact numerical ranges set forth in this paragraph.

[0057] In various embodiments, width W1 is in a range from 5 cm to 250 cm, from about 10 cm to about 250 cm, from about 15 cm to about 250 cm, from about 20 cm to about 250 cm, from about 25 cm to about 250 cm, from about 30 cm to about 250 cm, from about 35 cm to about 250 cm, from about 40 cm to about 250 cm, from about 45 cm to about 250 cm, from about 50 cm to about 250 cm, from about 55 cm to about 250 cm, from about 60 cm to about 250 cm, from about 65 cm to about 250 cm, from about 70 cm to about 250 cm, from about 75 cm to about 250 cm, from about 80 cm to about 250 cm, from about 85 cm to about 250 cm, from about 90 cm to about 250 cm, from about 95 cm to about 250 cm, from about 100 cm to about 250 cm, from about 110 cm to about 250 cm, from about 120 cm to about 250 cm, from about 130 cm to about 250 cm, from about 140 cm to about 250 cm, from about 150 cm to about 250 cm, from about 5 cm to about 240 cm, from about 5 cm to about 230 cm, from about 5 cm to about 220 cm, from about 5 cm to about 210 cm, from about 5 cm to about 200 cm, from about 5 cm to about 190 cm, from about 5 cm to about 180 cm, from about 5 cm to about 170 cm, from about 5 cm to about 160 cm, from about 5 cm to about 150 cm, from about 5 cm to about 140 cm, from about 5 cm to about 130 cm, from about 5 cm to about 120 cm, from about 5 cm to about 110 cm, from about 5 cm to about 110 cm, from about 5 cm to about 100 cm, from about 5 cm to about 90 cm, from about 5 cm to about 80 cm, or from about 5 cm to about 75 cm. In other embodiments, W1 falls within any one of the exact numerical ranges set forth in this paragraph.

[0058] In various embodiments, length LI is in a range from about 5 cm to about 1500 cm, from about 50 cm to about 1500 cm, from about 100 cm to about 1500 cm, from about 150 cm to about 1500 cm, from about 200 cm to about 1500 cm, from about 250 cm to about 1500 cm, from about 300 cm to about 1500 cm, from about 350 cm to about 1500 cm, from about 400 cm to about 1500 cm, from about 450 cm to about 1500 cm, from about 500 cm to about 1500 cm, from about 550 cm to about 1500 cm, from about 600 cm to about 1500 cm, from about 650 cm to about 1500 cm, from about 650 cm to about 1500 cm, from about 700 cm to about 1500 cm, from about 750 cm to about 1500 cm, from about 800 cm to about 1500 cm, from about 850 cm to about 1500 cm, from about 900 cm to about 1500 cm, from about 950 cm to about 1500 cm, from about 1000 cm to about 1500 cm, from about 1050 cm to about 1500 cm, from about 1100 cm to about 1500 cm, from about 1150 cm to about 1500 cm, from about 1200 cm to about 1500 cm, from about 1250 cm to about 1500 cm, from about 1300 cm to about 1500 cm, from about 1350 cm to about 1500 cm, from about 1400 cm to about 1500 cm, or from about 1450 cm to about 1500 cm. In other embodiments, LI falls within any one of the exact numerical ranges set forth in this paragraph.

[0059] In various embodiments, one or more radius of curvature (e.g., R shown in FIGS. 2A and 4A) of glass sheet 12 is about 20 mm or greater. For example, R may be in a range from about 20 mm to about 10,000 mm, from about 30 mm to about 10,000 mm, from about 40 mm to about 10,000 mm, from about 50 mm to about 10,000 mm, from about 60 mm to about 10,000 mm, from about 70 mm to about 10,000 mm, from about 80 mm to about 10,000 mm, from about 90 mm to about 10,000 mm, from about 100 mm to about 10,000 mm, from about 120 mm to about 10,000 mm, from about 140 mm to about 10,000 mm, from about 150 mm to about 10,000 mm, from about 160 mm to about 10,000 mm, from about 180 mm to about 10,000 mm, from about 200 mm to about 10,000 mm, from about 220 mm to about 10,000 mm, from about 240 mm to about 10,000 mm, from about 250 mm to about 10,000 mm, from about 260 mm to about 10,000 mm, from about 270 mm to about 10,000 mm, from about 280 mm to about 10,000 mm, from about 290 mm to about 10,000 mm, from about 300 mm to about 10,000 mm, from about 350 mm to about 10,000 mm, from about 400 mm to about 10,000 mm, from about 450 mm to about 10,000 mm, from about 500 mm to about 10,000 mm, from about 550 mm to about 10,000 mm, from about 600 mm to about 10,000 mm, from about 650 mm to about 10,000 mm, from about 700 mm to about 10,000 mm, from about 750 mm to about 10,000 mm, from about 800 mm to about 10,000 mm, from about 900 mm to about 10,000 mm, from about 950 mm to about 10,000 mm, from about 1000 mm to about 10,000 mm, from about 1250 mm to about 10,000 mm, from about 20 mm to about 1400 mm, from about 20 mm to about 1300 mm, from about 20 mm to about 1200 mm, from about 20 mm to about 1100 mm, from about 20 mm to about 1000 mm, from about 20 mm to about 950 mm, from about 20 mm to about 900 mm, from about 20 mm to about 850 mm, from about 20 mm to about 800 mm, from about 20 mm to about 750 mm, from about 20 mm to about 700 mm, from about 20 mm to about 650 mm, from about 20 mm to about 600 mm, from about 20 mm to about 550 mm, from about 20 mm to about 500 mm, from about 20 mm to about 450 mm, from about 20 mm to about 400 mm, from about 20 mm to about 350 mm, from about 20 mm to about 300 mm, or from about 20 mm to about 250 mm. In other embodiments, R1 falls within any one of the exact numerical ranges set forth in this paragraph.

[0060] The various embodiments of the vehicle interior system may be incorporated into vehicles such as trains, automobiles (e.g., cars, trucks, buses and the like), sea craft (boats, ships, submarines, and the like), and aircraft (e.g., drones, airplanes, jets, helicopters and the like).

Strengthened Glass Properties

[0061] As noted above, glass sheet 12 may be strengthened. In one or more embodiments, glass sheet 12 may be strengthened to include compressive stress that extends from a surface to a depth of compression (DOC). The compressive stress regions are balanced by a central portion exhibiting a tensile stress. At the DOC, the stress crosses from a positive (compressive) stress to a negative (tensile) stress.

[0062] In various embodiments, glass sheet 12 may be strengthened mechanically by utilizing a mismatch of the coefficient of thermal expansion between portions of the article to create a compressive stress region and a central region exhibiting a tensile stress. In some embodiments, the glass sheet may be strengthened thermally by heating the glass to a temperature above the glass transition point and then rapidly quenching.

[0063] In various embodiments, glass sheet 12 may be chemically strengthened by ion exchange. In the ion exchange process, ions at or near the surface of the glass sheet are replaced by - or exchanged with - larger ions having the same valence or oxidation state. In those embodiments in which the glass sheet comprises an alkali aluminosilicate glass, ions in the surface layer of the article and the larger ions are monovalent alkali metal cations, such as Li ⁺ , Na ⁺ , K ⁺ , Rb ⁺ , and Cs ⁺ . Alternatively, monovalent cations in the surface layer may be replaced with monovalent cations other than alkali metal cations, such as Ag ⁺ or the like. In such embodiments, the monovalent ions (or cations) exchanged into the glass sheet generate a stress.

[0064] Ion exchange processes are typically carried out by immersing a glass sheet in a molten salt bath (or two or more molten salt baths) containing the larger ions to be exchanged with the smaller ions in the glass sheet. It should be noted that aqueous salt baths may also be utilized. In addition, the composition of the bath(s) may include more than one type of larger ions (e.g., Na+ and K+) or a single larger ion. It will be appreciated by those skilled in the art that parameters for the ion exchange process, including, but not limited to, bath composition and temperature, immersion time, the number of immersions of the glass sheet in a salt bath (or baths), use of multiple salt baths, additional steps such as annealing, washing, and the like, are generally determined by the composition of the glass sheet (including the structure of the article and any crystalline phases present) and the desired DOC and CS of the glass sheet that results from strengthening. Exemplary molten bath compositions may include nitrates, sulfates, and chlorides of the larger alkali metal ion. Typical nitrates include KNO3, NaNCh, LiNCh, NaS04 and combinations thereof. The temperature of the molten salt bath typically is in a range from about 380°C up to about 450°C, while immersion times range from about 15 minutes up to about 100 hours depending on glass sheet thickness, bath temperature and glass (or monovalent ion) diffusivity.

However, temperatures and immersion times different from those described above may also be used.

[0065] In one or more embodiments, the glass sheets may be immersed in a molten salt bath of 100% NaNCh, 100% KNO3, or a combination of NaNCh and KNO3 having a temperature from about 370 °C to about 480 °C. In some embodiments, the glass sheet may be immersed in a molten mixed salt bath including from about 5% to about 90% KNO3 and from about 10% to about 95% NaNCh. In one or more embodiments, the glass sheet may be immersed in a second bath, after immersion in a first bath. The first and second baths may have different compositions and/or temperatures from one another. The immersion times in the first and second baths may vary. For example, immersion in the first bath may be longer than the immersion in the second bath.

[0066] In one or more embodiments, the glass sheet may be immersed in a molten, mixed salt bath including NaNCh and KNCh (e.g., 49%/51%, 50%/50%, 51%/49%) having a temperature less than about 420 °C (e.g., about 400 °C or about 380 °C). for less than about 5 hours, or even about 4 hours or less.

[0067] Ion exchange conditions can be tailored to provide a “spike” or to increase the slope of the stress profile at or near the surface of the resulting glass sheet. The spike may result in a greater surface CS value. This spike can be achieved by a single bath or multiple baths, with the bath(s) having a single composition or mixed composition, due to the unique properties of the glass compositions used in the glass sheets described herein. [0068] In one or more embodiments, where more than one monovalent ion is exchanged into the glass sheet, the different monovalent ions may exchange to different depths within the glass sheet (and generate different magnitudes stresses within the glass sheet at different depths). The resulting relative depths of the stress-generating ions can be determined and cause different characteristics of the stress profile.

[0069] CS is measured using those means known in the art, such as by surface stress meter (FSM) using commercially available instruments such as the FSM-6000, manufactured by Orihara Industrial Co., Ltd. (Japan). Surface stress measurements rely upon the accurate measurement of the stress optical coefficient (SOC), which is related to the birefringence of the glass. SOC in turn is measured by those methods that are known in the art, such as fiber and four point bend methods, both of which are described in ASTM standard C770-98 (2013), entitled “Standard Test Method for Measurement of Glass Stress-Optical Coefficient,” the contents of which are incorporated herein by reference in their entirety, and a bulk cylinder method. As used herein CS may be the “maximum compressive stress” which is the highest compressive stress value measured within the compressive stress layer. In some embodiments, the maximum compressive stress is located at the surface of the glass sheet. In other embodiments, the maximum compressive stress may occur at a depth below the surface, giving the compressive profile the appearance of a “buried peak.”

[0070] DOC may be measured by FSM or by a scattered light polariscope (SCALP) (such as the SCALP-04 scattered light polariscope available from Glasstress Ltd., located in Tallinn Estonia), depending on the strengthening method and conditions. When the glass sheet is chemically strengthened by an ion exchange treatment, FSM or SCALP may be used depending on which ion is exchanged into the glass sheet. Where the stress in the glass sheet is generated by exchanging potassium ions into the glass sheet, FSM is used to measure DOC. Where the stress is generated by exchanging sodium ions into the glass sheet, SCALP is used to measure DOC. Where the stress in the glass sheet is generated by exchanging both potassium and sodium ions into the glass, the DOC is measured by SCALP, since it is believed the exchange depth of sodium indicates the DOC and the exchange depth of potassium ions indicates a change in the magnitude of the compressive stress (but not the change in stress from compressive to tensile); the exchange depth of potassium ions in such glass sheets is measured by FSM. Central tension or CT is the maximum tensile stress and is measured by SCALP. [0071] In one or more embodiments, the glass sheet may be strengthened to exhibit a DOC that is described as a fraction of the thickness T1 of the glass sheet 12 (as described herein). For example, in one or more embodiments, the DOC may be equal to or greater than about 0.05T1, equal to or greater than about 0.1T1, equal to or greater than about 0.11T1, equal to or greater than about 0.12T1, equal to or greater than about 0.13T1, equal to or greater than about 0.14T1, equal to or greater than about 0.15T1, equal to or greater than about 0.16T1, equal to or greater than about 0.17T1, equal to or greater than about 0.18T1, equal to or greater than about 0.19T1, equal to or greater than about 0.2T1, equal to or greater than about 0.21T1. In some embodiments, the DOC may be in a range from about 0.08T1 to about 0.25T1, from about 0.09T1 to about 0.25T1, from about 0.18T1 to about 0.25T1, from about 0.11T1 to about 0.25T1, from about 0.12T1 to about 0.25T1, from about 0.13T1 to about 0.25T1, from about 0.14T1 to about 0.25T1, from about 0.15T1 to about 0.25T1, from about 0.08T1 to about 0.24T1, from about 0.08T1 to about 0.23T1, from about 0.08T1 to about 0.22T1, from about 0.08T1 to about 0.21T1, from about 0.08T1 to about 0.2T1, from about 0.08T1 to about 0.19T1, from about 0.08T1 to about 0.18T1, from about 0.08T1 to about 0.17T1, from about 0.08T1 to about 0.16T1, or from about 0.08T1 to about 0.15T1. In some instances, the DOC may be about 20 pm or less.
