FIELD OF THE INVENTION

[0001] The invention relates to aircraft seating for any seat class and flight range where a shareable armrest is located between passenger seats, and can be further applicable to any other field where seats are placed side by side with a shareable armrest located between passenger seats including but not limited to buses, trains, movie theaters, and the like.

BACKGROUND

[0002] Common carriers, such as passenger airlines, bus lines, train lines, and passenger vehicles frequently include passenger seats. In many cases, such as with passenger aircraft, and especially in Economy cabin, passenger seats are arranged adjacent to each other with a single armrest located between two passenger seats. These armrests therefore become shareable armrests, which can result in both tension between passengers over fair share and concern about germs and virus transmission.

[0003] U.S. Patent No. 9,828,101 describes an armrest structure having two support plates that pivot between a vertical orientation and a horizontal orientation. In the vertical orientation, the support plates are positioned adjacent a central wall to form a conventional shared armrest structure for use during taxi, take-off, and landing (“TTL”) conditions of a flight. In the horizontal orientation, the support plates are positioned at a 90 degree angle to the central wall to create a divided armrest for use during non-TTL portions of the flight. While the central wall provides a physical barrier between passengers’ arms and an equivalent and fair distribution of armrest space, it fails to provide any of these benefits during TTL conditions or at any other time when the support plates are in the vertical position (such as for a high percentile passenger having a large waist where the support plate is unable to rotate downward into the horizontal position). Moreover, even in the horizontal orientation, the available surface to support a passengers’ arm is limited to the horizontal surface of the support plate only.

[0004] U.S. Patent No. 9,986,841 describes an armrest structure having a physical barrier between passengers’ arms that utilizes a pair of concave surfaces that join along a central line along the armrest structure. While this structure provides a physical barrier between passengers’ arms and an equivalent and fair distribution of armrest space, it fails to provide any means of extending the support surface as desired by the passenger during non- TTL conditions. As a result, passengers may experience a feeling of not having enough space for resting their arms.

[0005] To address these issues, it is desirable to create an armrest that includes a nonintrusive design that maintains a physical barrier between passengers’ arms throughout the flight, including taxi, take-off, and landing (“TTL”) conditions. The goals of such a design are to define equivalent and fair armrest spaces for each passenger sharing the same armrest, to avoid intrusion into a passenger’s private space, and to avoid contact between passengers as much as possible, and to accomplish these goals during all the phases of a flight. The nonintrusive armrest is responsive to complaints and demands about unfair sharing of current armrest designs because it provides passengers with the ability to delimit and possess their own space. Moreover, as a direct consequence of the COVID-19 pandemic, the non-intrusive armrest avoids arm/prevents physical contact between passengers as much as possible and at all times during a flight, thus reducing a potential spread of germs between passengers.

[0006] Furthermore, it may be desirable that such a non-intrusive armrest design can be extended with a physical extension of the armrest to provide additional support for a passenger’s arm during the flight, particularly outside of TTL conditions. Such an extension may have a concave shape, which provides a greater support surface for a passenger’s arm by contouring to a curvature of a passenger’s arm, rather than providing a flat surface that provides minimal contact points for a passenger’s arm.

[0007] Such a design can be used in any seating configuration and any aircraft class seating where passenger seats are placed side by side and having a single armrest positioned between two passenger seats. For example, such an armrest could also be used in other fields where seats are placed side by side with an armrest to be shared between people, such as buses, trains, movie theatres, etc.

DETAILED DESCRIPTION

[0030] The subject matter of embodiments of the present invention is described here with specificity to meet statutory requirements, but this description is not necessarily intended to limit the scope of the claims. The claimed subject matter may be embodied in other ways, may include different elements or steps, and may be used in conjunction with other existing or future technologies. This description should not be interpreted as implying any particular order or arrangement among or between various steps or elements except when the order of individual steps or arrangement of elements is explicitly described.

[0031] According to certain embodiments of the present invention, as illustrated in FIGS. 1-17, a passenger seat 1 may comprise a non-intrusive and extendable armrest 10, which in turn comprises a base component 12 and two adjustable components 14.

[0032] In some embodiments, as shown in FIGS. 2-9 and 12-15, the base component 12 may further comprise a stationary divider 15 that is positioned to evenly divide the armrest 10 between the two passenger seats. The divider 15 is a vertical wall that extends approximately along a centerline of the armrest 10. In further embodiments, the divider 15 may have a curved, angular, or other design or other configuration that evenly divides the armrest 10 surface between the two passenger seats.

[0033] As shown in FIGS. 2-17, each adjustable component 14 comprises a retracted support surface 16 and an extended support surface 18. Each adjustable component 14 may be movably coupled to a recessed area 20 within the base component 12. In certain embodiments, the adjustable component 14 is configured to move between a retracted position 22 (as shown in FIGS. 2, 6, 9-10, 12, 14, 16) and an extended position 24 (as shown in FIGS. 4-5, 8, 11, 13, 15, 17). For example, as shown in FIGS. 2-17, each adjustable component 14 is pivotably coupled to the base component 12 at a pivot location 26. In other embodiments, the adjustable component 14 may be movably coupled to the base component 12 using a slide, a spring, or any other joining mechanism that provides for linear or rotational movement of the adjustable component 14 relative to the base component 12.

[0034] In the retracted position 22, according to some embodiments as shown in FIGS.

2, 6, 9 the adjustable component 14 may be oriented relative to the base component 12 so that the retracted support surface 16 is presented as the contact surface for a passenger’s arm, and the extended support surface 18 is positioned adjacent the divider 15.

[0035] In certain embodiments, as shown in FIGS. 2, 6, 9-10, 14, and 16, the retracted support surface 16 has a concave configuration, which provides a larger support surface for a passenger’s arm than a conventional flat armrest surface by better contouring to the rounded shape of the arm. The concave configuration is particularly beneficial in the retracted position because each passenger is limited to one-half of the lateral width of a conventional armrest. Thus, adding the concave configuration to the retracted support surface 16 effectively increases the overall armrest surface area without extending the lateral width of the armrest beyond that of a conventional armrest, which is explained in more detail below.

[0036] In addition to providing a more ergonomic armrest support, the arrangement of the retracted support surfaces 16 in the retracted position 22 also provides an equivalent and fair share of the armrest 10 to each passenger via the symmetric arrangement of the adjustable components 14 along the base component 12. The retracted position 22 also has a non-intrusive design that maintains a physical barrier between the passenger’s arms to prevent intrusion and arm contact between passengers as much as possible, thereby reducing a potential spread of germs between passengers.

[0037] In the extended position 24, as best illustrated in FIGS. 4, 8, 11, 13, 15, and 17, the adjustable component 14 may be oriented relative to the base component 12 so that the extended support surface 18 is presented as the contact surface for a passenger’s arm, and the retracted support surface 16 is facing downward toward a passenger’s leg when the passenger is seated in the passenger seat 1. In some embodiments, the extended support surface 18 has a flat configuration similar to that of a conventional armrest surface.

[0038] As illustrated in FIGS. 4, 8, 11, 13, 15, and 17, the extended support surface 18 extends the lateral width of the armrest beyond that of a conventional armrest. In the extended position 24, the retracted support surface 16 may provide additional comfort to the passenger by providing a concave surface that better contours to the rounded shape of the passenger’s leg that is likely located below the adjustable component 14 in the extended position 24.

[0039] In some embodiments, such as those shown in FIGS. 2-4, 6-8, and 10-11, the height of the support surface of the armrest 10 in both the retracted position 22 and the retracted position 24 remains approximately the same. The continuity in the height in both positions 22, 24 can be more ergonomic by allowing the passenger to maintain the same seated position when using the armrest 10.

[0040] In order to facilitate rotation of the adjustable component 14 between positions, as shown in FIGS. 2-4 and 6-11, a portion 28 of the adjustable component 14 may be positioned within a recessed area 20 of the base component 12 that houses the pivot location 26. The portion 28 may have a rounded contour that allows it to more easily move within the recessed area 20 without binding against any surfaces within the recessed area 20. In other embodiments, the portion 28 can have a circular, elliptical, polygonal, or any other suitable shape that does not bind against any surfaces within the recessed area 20. For example, the bottom surface could be removed (as it is not visible by passengers), in which case there would be no constraint on binding.

[0041] As a result, as illustrated in FIGS. 6-8, when the adjustable component 14 is rotated into the extended position 24, some of the rounded surface of the portion 28 is also rotated out of the recessed area 20 which can result in the formation of a gap 32 between the extended support surface 16 and the divider 15. A cover 34 may be positioned over the gap 32 to provide a smooth surface to support a passenger’s arm. The adjustable component 14 may have an opening or slit 36 that is shaped to receive the cover 34 and allow the adjustable component 14 to slide over the cover 34 as it rotates upward into the retracted position 22. [0042] In other embodiments, the cover 34 may be attached to the adjustable component 14 in such a way that allows the cover 34 to move into position over the gap 32, such as with a spring-loaded connection that holds the cover 34 in a horizontal position over the gap 32 in the extended position 24 and then releases the cover 34 when the adjustable component 14 rotates into the retracted position 22. Any other suitable configuration of the adjustable component 14 may be utilized that provides a comfortable and supported surface in the extended position 24.

[0043] According to some embodiments, as shown in FIGS. 6-8, the adjustable component 14 may be held in the extended position 24 through the use of one or more stop mechanisms 38, which prevent further rotation or other movement of the adjustable component 14 in the extended direction. In further embodiments, the mechanism 38 may be located in the gap 32 (identified in FIG. 8).

[0044] As illustrated in FIG. 9, the adjustable component 14 may be held in the retracted position 24 through the use of a retention device 40 (including but not limited to one or more springs, latches, clasps, hook and loop fasteners, or other suitable releasable connection devices) to releasably hold the adjustable component 14 in place. A person of ordinary skill in the relevant art will understand that any suitable device may be used that can maintain the adjustable component 14 in the retracted position 22 until the passenger wishes to deploy it into the extended position 24.

[0045] In some embodiments, as shown in FIGS. 2-4, 6-8, 10-11, the arc of rotation of the adjustable component 14 between the retracted position 22 and the extended position 24 is approximately 90 degrees. However, the arc may be more or less than 90 degrees, depending on the location and configuration of the retracted support surface 16 and the extended support surface 18 with respect to the overall geometry of the adjustable component 14, the configuration of the base component 12, and the configuration of the stop mechanism 38. [0046] In certain embodiments, as illustrated in FIG. 2 and as described above, the completely retracted position 22 of the armrest 10 (meaning both of the adjustable components 14 are in the retracted position 22) comprises a width (wac). Wac is the sum of the width of the retracted position 22 of each adjustable component 14 (w&) plus a width of the divider 15. If the divider 15 is not present, then wac = 2*wfc. In certain embodiments, the value of Wac may remain approximately the same as the width dimension for conventional shareable armrests, which currently is approximately 2 inches for economy class passenger seats. In other embodiments, the value of Wac may be smaller or larger than the width dimension for conventional shareable armrests.

[0047] In certain embodiments, as illustrated in FIG. 4 and as described above, the completely extended position 24 of the armrest 10 (meaning both of the adjustable components 14 are in the extended position 24) comprises a total width (wao). Wao is the sum of the width of the extended position 24 of each adjustable component 14 (wfo) plus a width of the divider 15. If the divider 15 is not present, then wao = 2*wf ₀ . In certain embodiments, the value of the wao may depend on the width of the passenger seat and certification limitations. In certain embodiments, the difference between wao and wac may be at least 1 inch in certain cases. In other cases, the difference between wao and wac may be at least 2 inches, further may be at least 3 inches, and still further may be at least 4 inches.

[0048] For example, in some embodiments such as those depicted in FIGS. 2-4, 6-8, and 10-11, the adjustable component 14 is configured and attached to the base component 12 in such a way that the width wfo of the adjustable component 14 is approximately the same as the overall height hr of the armrest 10. Thus, in these embodiments, the value of wfo may not exceed the maximum allowable height hr of the armrest 10. In further embodiments, the height hr may exceed the value of wfo, depending on the position of the pivot location 26 within the base component 12. [0049] Generally speaking, the support surface of an armrest may be positioned to comfortably support a passenger’s forearms without raising the passenger’s shoulders. This height is typically about 7-9 inches above a surface of the passenger seat 1. Thus, the maximum value of hr (and thus the maximum value of wfo in some embodiments) may not exceed about 10 inches in certain cases, may be further limited to a maximum height of 9 inches, may be further limited to a maximum height of 8 inches, and may be further limited to a maximum height of 7 inches.

[0050] An additional limitation on the maximum height hr of the armrest 10 may be based on regulations concerning how the armrest 10 is raised and stowed between the passenger seat backs. For example, certain guidelines require a bottom side of the armrest 10 to be approximately flush with a front surface of the passenger seat back 1 when the armrest 10 is raised and stowed between the passenger seat backs. If the armrest 10 is also configured so as not to extend past a rear surface of the passenger seat back, then the maximum value of hr is limited to the overall thickness of the passenger seat back.

[0051] Thus, in cases where the passenger seat back thickness is only 6 inches for example, the maximum value of hr (and thus the value of wfo) may not exceed about 6 inches in certain cases. In other cases, the maximum value of hr (and thus the maximum value of wfo in some embodiments) may be further limited to a maximum height of 5 inches, may be further limited to a maximum height of 4 inches, and may be further limited to a maximum height of 3 inches.

[0052] Other embodiments of the present invention may utilize pivots or hinges, flaps with flat or concave surfaces, and may be fully or partially non-intrusive. For example, as shown in FIG. 10-11, the armrest 10 may be configured so that the adjustable components 14 form a non-intrusive physical barrier in the retracted position 22, but the armrest 10 does not have a non-intrusive physical barrier in the extended position 24. In these embodiments, this result is accomplished by removing the divider 15 from the base component 12.

[0053] In additional embodiments, such as the examples shown in FIG. 12-13, the armrest 10 may be configured so that a non-intrusive physical barrier is present in the extended position 24, but not in the retracted position 22. In these embodiments, this result is accomplished with a configuration where the adjustable components 14 are joined to the base component 12 at a higher pivot location 26. The higher pivot location 26 allows the adjustable components 14 to stow against the divider 15 in the retracted position 22, thereby creating a flat armrest surface that lacks a physical divider in the retracted position 22. In contrast, because of the higher pivot location 26, the adjustable components 14 are able to rotate approximately 180 degrees until the adjustable component 14 is positioned adjacent the base component 12, thereby leaving the divider 15 exposed to form a physical barrier in the extended position 24.

[0054] In yet other embodiments, such as the examples shown in FIG. 14-15, the armrest 10 may be configured so that a non-intrusive physical barrier is present in the extended position 24 and in the retracted position 22, while also incorporating a higher pivot location 26. In these embodiments, the previous embodiment is modified to increase the height of the divider 15, while also incorporating a concave shape into the adjustable components 14. Like the previous embodiment, the higher pivot location 26 allows the adjustable components 14 to stow against the divider 15 in the retracted position 22 so that the concave shapes of the adjustable components 14 form a physical barrier in the retracted position 22. The adjustable components 14 are then able to rotate approximately 180 degrees until the adjustable component 14 is positioned adjacent the base component 12, thereby leaving the divider 15 exposed to form a physical divider in the extended position 24. [0055] In further embodiments, such as the examples shown in FIG. 16-17, the armrest 10 may be configured so that the adjustable components 14 form a non-intrusive physical barrier in the retracted position 22, but the armrest 10 does not have a non-intrusive physical barrier in the extended position 24. In these embodiments, this result is accomplished by removing the divider 15 from the base component 12. Like the previous embodiments, the higher pivot location 26 allows the adjustable components 14 to stow against each other in the retracted position 22 so that the concave shapes of the adjustable components 14 form a physical barrier in the retracted position 22. The adjustable components 14 are then able to rotate approximately 180 degrees until the adjustable component 14 is positioned adjacent the base component 12 in the extended position 24.
