TECHNICAL FIELD

The present invention relates to a door member; and to a vehicle door. More particularly, but not exclusively, the present invention relates to a door member for mounting a door seal. The present invention also relates to a door member defining an inner finisher and/or an outer finisher. The present invention also relates to a method of moulding a door member. Aspects of the invention relate to a door member, to a door, to a vehicle and to a method.

BACKGROUND

A primary door seal is mounted to a vehicle door frame to form a seal to prevent the ingress of water when the vehicle door is closed. The door seal can also provide insulation from external noises and vibrations. As illustrated in Figure 1 , it is known to use an adhesive tape T for mounting a primary seal S to a door panel P _D . When the vehicle door is closed, the primary seal S cooperates with a body panel P _B . The accurate location of the primary seal S requires appropriate manufacturing facilities as the adhesive tape T cannot be re-positioned. Moreover, if the door seal is to be replaced, the adhesive tape T must be removed and the door panel P _D cleaned to provide a suitable surface for bonding the replacement adhesive tape T.

An alternative technique is to use mechanical fasteners, such as clips, provided along the length of the seal. The mechanical fasteners typically retain the seal within a channel which is either formed in the door frame or attached to the door frame. Again, however, appropriate manufacturing facilities are required to secure the door seal in position. The attachment of a channel to the door frame can also necessitate a further manufacturing step.

At least in certain embodiments, the present invention sets out to overcome or ameliorate at least some of the above problems associated with the aforementioned prior art arrangements.

SUMMARY OF THE INVENTION

Aspects of the present invention relate to a door member, a vehicle door, a vehicle and a method of moulding a door member. According to a further aspect of the present invention, there is provided a door member for mounting to a vehicle door, the door member being injection moulded from a plastics material and comprising an integral door seal mounting channel for receiving a mounting portion of a primary door seal for sealingly engaging a vehicle body panel when the vehicle door is closed. The door seal mounting channel is moulded integrally with the door member. At least in some embodiments, the door seal mounting channel can be formed by first and second cooperating moulds without the need for moveable side cores. At least one first projection can be provided on said first sidewall for engaging the mounting portion of said door seal. The at least one first projection can be formed integrally with the door member and, in use, can cooperate with the mounting portion to retain the door seal in position. Thus, the door trim according to the present invention can retain the door seal without the need for additional fasteners and/or adhesive. The door member thereby simplifies assembly and servicing of the door. The door seal mounting channel can have a first sidewall and a second sidewall. The at least one first projection is provided on an inside of said first sidewall. The at least one first projection can project inwardly towards a centre of the door seal mounting channel. The at least one first projection can define a latch or retention feature for cooperating with the mounting portion of the door seal. The at least one first projection can comprise a guide surface for guiding the mounting portion into the door seal mounting channel. An underside of the at least one first projection can be adapted to engage the mounting portion of the door seal to retain the door seal in the door seal mounting channel. The underside of the at least one first projection can be defined by a male mould member. A first undercut can be formed on an underside of said at least one first projection for retaining the mounting portion of the door seal with the door seal mounting channel. The first undercut can form an acute angle or an obtuse angle with an adjacent surface of the first sidewall. Alternatively, the first undercut can be arranged substantially orthogonal with the adjacent surface of the first sidewall. A plurality of said first projections can be provided along the length of said first sidewall. At least one second projection can be provided on said second sidewall for engaging the mounting portion of said door seal. The at least one second projection can be provided on an inside of said second sidewall. The at least one second projection can project inwardly towards a centre of the door seal mounting channel. An underside of the at least one second projection can be adapted to engage the mounting portion of the door seal to retain the door seal in the door seal mounting channel. The underside of the at least one first projection can be defined by a male mould member. A second undercut can be formed on an underside of each said at least one second projection for retaining the mounting portion of the door seal with the door seal mounting channel. The second undercut can form an acute angle or an obtuse angle with an adjacent surface of the second sidewalk Alternatively, the second undercut can be arranged substantially orthogonal with the adjacent surface of the second sidewalk The at least one second projection can define a latch or retention feature for cooperating with the mounting portion of the door seal. A plurality of said second projections can be provided along the length of said second sidewalk

The at least one first projection and the at least one second projection can be arranged to oppose each other.

An aperture can be formed in said door seal mounting channel proximal said at least one first projection and/or said at least one second projection. The aperture can be formed by a mould member (typically a male mould) configured to form the underside of said at least one first projection and/or an underside of said at least one second projection. The aperture can be adapted (in relation to its size and/or position) to facilitate retraction of said mould member. When the door seal mounting channel is being moulded, the mould member can extend through said aperture. Thus, the mould member extends through the door seal mounting channel to define the underside of the at least one first projection and/or the underside of the at least one second projection. The mould member can be retracted through said aperture when the door member has been moulded. The mould member can also define a portion of said first sidewall and/or said second sidewalk For example, the mould member can define the portion of the first sidewall and/or the second sidewall extending between the aperture and the respective first and second projections. Each aperture can extend longitudinally for a length equal to or greater than the longitudinal length of the first projection and/or second projection associated therewith. Each aperture can extend partially or completely across the width of said seal mounting channel (i.e. in a transverse direction). The extent of each aperture in said transverse direction can be equal to or greater than the corresponding extent of the corresponding projection in said transverse direction. Rather than form a single aperture extending across the width of the seal mounting channel, first and second apertures could be formed in the seal mounting channel for receiving mould members configured to define the underside of the respective first and second projections.

Each aperture can be offset from the corresponding first and/or second projection in an axial direction to enable the door member to be removed from the mould member during fabrication. Once the door member has been moulded, the door member and the mould member are moved relative to each other in said axial direction to separate the door member from the mould member. The axial direction is typically substantially parallel to an inner surface of the first and/or second sidewall of said door seal mounting channel.

According to a further aspect of the present invention, there is provided a door member for mounting to a vehicle door, the door member being injection moulded from a plastics material and comprising a door seal mounting channel for receiving a mounting portion of a door seal; at least one first projection being provided on a first sidewall of the door seal mounting channel for engaging the mounting portion of said door seal; wherein an aperture is formed in said door seal mounting channel proximal each said at least one first projection for retraction of a mould member which forms the underside of said first projection during injection moulding of the door member.

The door member can form an inner finisher (or capping) and/or an outer finisher (or capping). The door member can, for example, form a B-post of the vehicle door. The outer finisher can define an outer surface of said B-post. The inner finisher can define an inner surface of said B-post.

The door member can be profiled to cooperate with said upper window frame to form a seal along the length of the door member. The ingress of moisture between the door member and the upper window frame can thereby be inhibited. A sealing member, such as an elastomeric strip, can optionally be provided between the door member and the upper window frame.

The door member can further comprise a window seal mounting channel for mounting a glass run seal. The window seal can be a run seal for sealingly engaging the window. The window seal mounting channel can be moulded integrally with the door member.

At least one end of the door seal mounting channel can define an inset section for forming a flush lap joint. A width and/or depth of the door seal mounting channel can be reduced to form said inset section. The inset section allows an outer surface of the door seal mounting channel to be substantially continuous across a joint. The door seal can thereby form a continuous seal.

The door member can be fixedly mounted to the upper window frame. The upper window frame can be formed from metal, such as aluminium or steel. The window frame can be an extrusion, for example. The window frame can comprise a curved section and an upright section. The present invention also relates to the combination of a door member as described herein with the upper window frame. The upper window frame can comprise a door seal mounting flange which forms a continuation of the door seal mounting channel. For example, the door seal mounting flange can be a continuation of a first sidewall of the door seal mounting channel. The door seal mounting flange can match the profile of the first sidewall of the door seal mounting channel. The door seal mounting flange can extend along a top section of said upper window frame. The upper window frame could define a door seal mounting channel.

According to a further aspect of the present invention, there is provided a method of moulding a door member as described herein, wherein said door seal mounting channel and said at least one first projection are moulded integrally by a first mould member and a second mould member. The first mould member and/or the second mould member can translate along an axis to split the mould and enable the door member to be removed. The door seal mounting channel and the at least one first projection can be formed without the use of a separate moveable core to release the door member. This arrangement can reduce the complexity of the mould. The at least one second projection can also be moulded integrally by said first and second mould members.

According to a further aspect of the present invention, there is provided a method of injection moulding a door member from a plastics material, the door member comprising a door seal mounting channel for receiving a mounting portion of a door seal; the method comprising using a first mould member and a second mould member to integrally mould said door seal mounting channel and at least one first projection on a first sidewall of said door seal mounting channel; wherein the first mould member forms an underside of said at least one first projection and the method comprises retracting the first mould member through an aperture formed in said door seal mounting channel proximal to said at least one first projection.

The first mould member can also define an underside of said at least one second projection. Alternatively, separate mould members could be provided to define the undersides of the first and second projections.

The first mould member can define: (a) the aperture in said door seal mounting channel; and/or (b) a section of said first sidewall extending between said aperture and said first projection; and/or (c) a section of said second sidewall extending between said aperture and said second projection. The second mould member can form an upper surface of said at least one first projection and/or an upper surface of said at least one second projection.

The features of the door member described herein can be incorporated into other injection moulded components. According to a still further aspect of the present invention there is provided an injection moulded component comprising a channel for receiving a mounting portion of a seal; at least one first projection being provided on a first sidewall of the channel for engaging the mounting portion of said seal; and wherein an aperture is formed in said seal mounting channel proximal each said at least one first projection for retraction of a mould member which forms an underside of said at least one first projection during injection moulding of the component. Each aperture can extend longitudinally for a length equal to or greater than the longitudinal length of the first projection and/or second projection associated therewith. Each aperture can extend partially or completely across the width of said mounting channel (i.e. in a transverse direction). The extent of each aperture in said transverse direction can be equal to or greater than the corresponding extent of the corresponding projection in said transverse direction. Rather than form a single aperture extending across the width of the seal mounting channel, first and second apertures could be formed in the seal mounting channel for receiving mould members configured to define the underside of the respective first and second projections.

The method(s) of moulding a door member described herein can be implemented into methods for moulding other components. According to a yet further aspect of the present invention there is provided a method of injection moulding a component comprising a mounting channel having a first sidewall; the method comprising using a first mould member and a second mould member to integrally mould said mounting channel and at least one first projection on said first sidewall; wherein the first mould member forms an underside of said at least one first projection and the method comprises retracting the first mould member through an aperture formed in said mounting channel proximal to said at least one first projection.

According to a further aspect of the present invention, there is provided a door member for mounting to an upper window frame of a vehicle door, the door member being moulded from a plastics material and comprising an inner post finisher and/or an outer post finisher, wherein said door member is profiled to cooperate with said upper window frame to form a seal. The door member can abut the upper window frame to form the seal. The seal can prevent the ingress of moisture between the door member and the upper window frame. The door member can be profiled to form the seal along the length of the door member. The door member can further comprise a window seal mounting channel for mounting a glass run seal. The glass run seal forms a groove in which a window can travel. The door member can further comprise an inner corner finisher. The door member can define a hand grab for opening and closing the vehicle door. One or more fixings can be provided on the door member for mounting top frame brightwork and/or an outer waist seal.

The door member can be fixedly mounted to said upper window frame. The door member can be bonded, mechanically fixed, or overmoulded to the upper window frame. The inner post finisher and the outer post finisher could be overmoulded simultaneously or in sequence. The door member could comprise a metal support. The door member could, for example, be overmoulded on said metal support. The door member could be manufactured as one piece, for example using mould sliders or gas injection methods.

The door member can further comprise a door seal mounting channel for receiving a mounting portion of a door seal. The door seal mounting channel can comprise a first sidewall and a second sidewalk At least one first projection can be provided on the first sidewall for engaging the mounting portion of said door seal. At least one second projection can be provided on the second sidewall for engaging the mounting portion of said door seal.

The upper window frame can comprise a door seal mounting flange which forms a continuation of the door seal mounting channel. The door seal mounting flange can extend along a top section of said upper window frame.

According to a further aspect of the present invention, there is provided an upper window frame comprising the door member of the type described herein.

A door trim panel 1 for forming part of a vehicle door structure in accordance with a first embodiment of the present invention will be described with reference to Figures 2 to 5.

The door trim panel 1 comprises an upper door seal mounting channel 3 defined by first and second sidewalls 5, 7 having respective first and second latching projections 9, 1 1 . The upper mounting channel 3 retains a primary door seal 13 for sealingly engaging a vehicle body panel 15 when the vehicle door is closed, as illustrated in Figure 2. A plurality of said first and second latching projections 9, 1 1 is formed along the length of the upper mounting channel 3 to engage the primary door seal 13. In the present embodiment, the first and second latching projections 9, 1 1 are arranged in opposing pairs. The door trim panel 1 is a one-piece plastics moulding formed by injection moulding. The sectional views in Figures 3A and 3B are at different positions along the upper mounting channel 3 and shows the intermittent arrangement of the first and second latching projections 9, 1 1 along the length of the upper mounting channel 3. A channel floor section 17 joins the first and second sidewalls 5, 7 of the upper mounting channel 3. As shown most clearly in Figure 4A, a rectangular aperture 18 is formed in the channel floor section 17 coincident with each pair of the first and second latching projections 9, 1 1 . The aperture 18 is formed by a male mould (not shown) which defines an undercut on an under side of the first and second latching projections 9, 1 1 . A female mould (not shown) forms a sloping upper side of the first and second latching projections 9, 1 1 for receiving the primary door seal 13. A sectional perspective view of the first and second latching projections 9, 1 1 and the aperture 18 is shown in Figure 4B. The upper mounting channel 3 and the latching projections 9, 1 1 are configured to enable moulding without movable cores (for example moveable side cores). Thus, the door trim panel 1 can be moulded in a mould consisting of said male and female moulds which can be separated to enable the moulded component to be removed. The ability to form the door trim panel 1 without movable cores reduces the complexity of the moulding process.

The door seal 13 is an elongate member having a uniform cross section which is formed by extruding an elastomeric material. The door seal 13 comprises a mounting portion 19 and a sealing portion 21. The mounting portion 19 comprises first and second strips 23, 25 which are pivotally connected to each other along a common edge 27 to form a live hinge. An elongate detent 29 is formed in an outside surface of the first strip 23 to cooperate with the first latching projections 9 formed in the first sidewall 5 of the upper mounting channel 3. The first and second strips 23, 25 are biased to an open position such that the second strip 25 cooperates with an inner surface of the second sidewall 7 to bias the door seal 13 towards the first sidewall 5. A distal end 31 of the second strip 25 cooperates with the second latching projections 1 1 to retain the mounting portion 19 within the upper mounting channel 3. The sealing portion 21 of the door seal 13 is conventional insofar as it comprises a closed D- shaped section 33 for sealingly engaging the vehicle body panel 15 when the vehicle door is closed. As shown in Figures 3A and 3B, a projecting edge 35 extends from said D-shaped section 33 and abuts an outer surface of the second sidewall 7 to form an outer seal 37. An inner surface 39 of the sealing portion 19 abuts the first sidewall 5 to form an inner seal 41 .

The mounting of the door panel trim 1 to the vehicle door structure will now be described with reference to Figures 5, 6 and 7. A side elevation of front and back vehicle doors 43, 45 of a motor vehicle are shown in Figure 5. The front of the front door 43 defines an A-post (A); the back of the front door 43 and the front of the back door 45 together define a B-post (B); and the back of the back door 45 defines a C-post (C). As shown most clearly in Figure 6, the door trim panel 1 described herein is located at the back of the front vehicle door 43 and forms a structural component of the B-post (B). Specifically, the door trim panel 1 forms a grab region which can be gripped by a user as they open and close the vehicle door. An external finisher 47 is mounted to the door trim panel 1 to provide an exterior contact surface.

The front vehicle door 43 comprises a lower door assembly 49 and an upper frame assembly 51 . The upper frame assembly 51 comprises a window frame 53 extruded from metal (for example aluminium or steel) and fixedly mounted to the lower door assembly 49. The window frame 53 comprises a curved upper section 55 and a rear section 57 which together surround a window 59 movably mounted in the front vehicle door 43. The rear section 57 of the window frame 53 extends substantially vertically and forms a front section of the B-post (B). A top frame finisher 61 , for example comprising brightwork, is mounted to the curved upper section 55.

A sectional view along line X-X is shown in Figure 7. The door trim panel 1 comprises a mounting bracket 63 which abuts the rear section 57 of the window frame 53 to form a seal along the length of the door trim panel 1. The mounting bracket 63 is mechanically attached to the rear section 57, for example using screws, rivets, bolts or other mechanical fasteners. A sealant or seal member could optionally be provided between the mounting bracket 63 and the window frame 53. The door trim panel 1 comprises an internal finisher 65 which, in use, hides the window frame 53 from view. The external finisher 47 is mounted to an outside of the door trim panel 1. A glass mounting channel 67 is formed between the mounting bracket 63 and the decorative finisher 47 to receive a glass run seal 69 for sealingly engaging the window 59.

A perspective view of the bottom of the door trim panel 1 is shown in Figures 8A and 8B. A door casing 71 forms part of the lower door assembly 49 and is configured to mate with the bottom of the door trim panel 1 . The door casing 71 is also injection moulded from a plastics material. The door casing moulding 71 comprises a lower door seal mounting channel 73 for retaining the door seal 13. The lower mounting channel 73 is defined by third and fourth sidewalls 75, 77 optionally having respective third and fourth latching projections (not shown) provided along its length. Figure 8A shows the door trim panel 1 and the door casing 71 coupled to each other; and Figure 8B shows the door casing 71 in isolation. An upper end of the lower mounting channel 73 defines an interface section 79 in which the width of the lower mounting channel 73 is reduced so as to locate inside the upper mounting channel 3. The fourth sidewall 77 of the lower mounting channel 73 has an outer Z-shaped inset 81 at the entry into said interface section 79. The inset 81 locates inside the second sidewall 7 allowing a flush lap joint to be formed at the junction between the second sidewall 7 and the fourth sidewall 77. In the present embodiment, a lower end of the first sidewall 5 also forms an inner Z-shaped inset 82 for receiving an upper end of the third sidewall 75. The second sidewall 77 has a reduced thickness for accommodating the outer Z-shaped inset 81 , as shown in Figure 8A. This arrangement is particularly advantageous as the interface between the outer surface of the second sidewall 7 and the fourth sidewall 77 is substantially continuous without any outwardly directed projections. Thus, a substantially uniform, uninterrupted surface is defined by the outer surfaces of the second sidewall 7 and the fourth sidewall 77 for cooperating with the projecting edge 35 of the sealing portion 21 of the door seal 13. The door seal 13 can thereby maintain a seal across the junction of the second sidewall 7 and the fourth sidewall 77. It will be appreciated that the interface section 79 could be defined at the bottom end of the upper mounting channel 3. Advantageously, the lower mounting channel 73 and the outer Z-shaped inset 81 can be moulded integrally using a two- part (male/female) mould without moveable side cores. The configuration of the upper mounting channel 3 according to the present invention allows the door seal 13 to be mechanically mounted to the door trim panel 1 without the need for separate clips or adhesive. The assembly of the door frame structure can therefore be simplified. This mounting arrangement also allows the door seal 13 to be removed and refitted/replaced without the need for door cleaning and re-attachment of an adhesive tape. The door trim panel 1 defines an internal finisher 65 for improving the appearance of the door frame structure. The door trim panel 1 also forms a structural component of the door frame structure and can improve strength and/or rigidity of the upper frame assembly 51 .

Moreover, the upper mounting channel 3 can provide a continuous, uniform mounting arrangement for the door seal 13 at the interface between the door trim panel 1 and the window frame 53. For example, the upper mounting channel 3 can be aligned with a matching seal mounting flange (not shown) formed in the window frame 53. The joint can be configured to form a substantially uniform outer surface to provide a continuous outer surface for the door seal 13. For example, a flush lap joint can be formed to join the upper mounting channel 3 and the seal mounting flange. A sectional view along line X-X of Figure 5 of a second embodiment of the door trim panel 101 according to the present invention is shown in Figure 9. Like reference numerals will be used for like components albeit incremented by 100 for clarity. The door trim panel 101 is a one-piece moulding which defines both the external finisher 147 and the internal finisher 165. The door trim panel 101 also defines the glass mounting channel 167 for receiving the glass run seal 169. The door trim panel 101 further comprises a reinforcing stringer 183 and optionally one or more transverse ribs (not shown) extending between the external finisher 147 and the internal finisher 165. The door seal mounting channel 103 for mounting the door seal 1 13 could optionally be formed integrally with the window frame 53 in the present embodiment.

The window frame 153 further comprises a keyed surface 185 for engaging the door trim panel 101 . The keyed surface 185 comprises a rectangular channel 187 for receiving an elongate protuberance 189 formed in the mounting bracket 163. The interaction of the channel 187 and the protuberance 189 forms a seal to prevent the ingress of moisture. The door trim panel 101 is mounted to the window frame by mechanical fasteners, such as screws, and optionally also an adhesive. The door trim panel 101 is also mounted to the lower door assembly 149 by mechanical fasteners 179.

The door trim panel 101 is a structural component and reinforces the window frame 153. In use, the user can apply a closing pressure to the door trim panel 101 to close the front vehicle door. The door trim panel 101 also defines the interior and exterior surfaces of the B- post and can improve the appearance of the front vehicle door.

It will be appreciated that various changes and modifications can be made to the door trim panel 1 ; 101 described herein without departing from the scope of the present invention. For example, the present invention has been described with reference to a vehicle door for providing entry to a vehicle cabin. However, it will be appreciated that the present invention could also be embodied in a vehicle door for providing access to a boot (trunk) or an engine bay.

Further aspects of the present invention are set out in the following numbered paragraphs: 1 . A door member for mounting to a vehicle door, the door member being injection moulded from a plastics material and comprising an integral door seal mounting channel for receiving a mounting portion of a primary door seal for sealingly engaging a vehicle body panel when the vehicle door is closed.
