Description

[0001] The invention relates to a pivotable backrest arrangement for a vehicle interior, comprising a backrest body with a cover and a receptacle for a housing shell designed to hold at least one drinking container, the housing shell having a circumferential collar. The invention also relates to a method for manufacturing such a backrest arrangement.

[0002] From DE 10 2013 204 000 A1, a pivoting backrest assembly for the interior of a passenger car is known. The backrest assembly is part of the backrest of a rear bench seat in the passenger car. The backrest assembly has a backrest body which is provided with padding in the form of a foam core. The backrest body is stabilized by a dimensionally stable frame structure which is pivotally mounted on the vehicle side in the area of ​​the backrest assembly by means of a pivot bearing. The backrest body is provided with a receptacle into which a housing shell is inserted, which is designed to hold at least one drinking container. The housing shell has a cover plate which is provided in the area of ​​the upper surface of the backrest body, relative to an armrest position of the backrest body that is pivoted approximately horizontally forwards.The housing shell has a bottom area which is held elastically in relation to a backrest surface of the backrest body, which is provided opposite the cover panel in the area of ​​a bottom.

[0003] The object of the invention is to create a swiveling backrest arrangement and a method for manufacturing it of the type mentioned above, which enable a visually appealing, cost-effective and compact design.

[0004] This problem is solved for the pivoting backrest assembly by ensuring that, in its assembled state, the collar covers the upholstery in the area of ​​one edge of the receptacle, and that the collar is positively, materially, or force-fitted to the upholstery. The solution according to the invention ensures that the upholstery in the area of ​​the upper surface of the backrest body, where the collar is positioned, does not wrinkle and is firmly connected to the collar. The housing shell itself is held firmly in the receptacle of the backrest body, thereby achieving a secure connection between the housing shell and the backrest body. The solution according to the invention is particularly advantageous for a backrest assembly in the form of a center armrest, which is pivotally mounted on the vehicle side in the area of ​​a rear seat bench. The rear seat bench is part of the interior of a passenger car.The backrest arrangement according to the invention is advantageously pivotably mounted between an upright rest position, in which the backrest arrangement is integrated into a backrest of the rear seat, and a forward and downward pivoted functional position, in which an open side of the backrest body's receptacle is oriented upwards, so that the collar of the housing shell is positioned in the area of ​​the upper side of the backrest body. This pivoted position forms an armrest position in which a person sitting on the rear seat can rest their arm on the upper side of the backrest body. Because the housing shell is open at the top in this armrest position of the backrest body and therefore accessible from above, it is also possible to place at least one drinking container in the housing shell. The housing shell, including the collar, is preferably made of a thermoplastic material.

[0005] In this embodiment of the invention, the backrest body is designed as a foam body. The foam body is made of an elastically compliant plastic foam material with a high pore density. The recess for the housing shell is formed in the foam body. In a reclined position, the foam body serves as padding, thus continuing the padding function of the backrest assembly even in the area of ​​the pivoting backrest assembly.

[0006] In a further embodiment of the invention, a support frame is provided, which is surrounded by the backrest body and to which a pivot bearing is assigned, which can be connected to pivot mounts on the vehicle side. The support frame is made of metal and preferably has longitudinal and transverse beams which are connected to a pivot axis. The pivot axis is preferably provided with bearing bolt sections that form the pivot bearing of the backrest assembly.

[0007] In a further embodiment of the invention, at least one locking clip is integrally formed on an outer surface of the housing shell, which can be positively connected to a corresponding section of the support frame. Preferably, two locking clips are integrally formed on opposite end faces of the housing shell, projecting outwards from an outer wall of the housing shell. The locking clips are preferably designed as omega clips, which have a substantially Ω-shaped cross-section that is open towards the underside. The at least one locking clip can be placed onto a cross member of the support frame from above and snapped into place, wherein a cross-section of the cross member is preferably designed to be complementary to a free cross-section of the locking clip. The at least one locking clip is advantageously designed such that it can also be released from the corresponding section of the support frame, in particular from the cross member, after being snapped into place.

[0008] In a further embodiment of the invention, the collar is provided on its underside with downward-projecting pins that penetrate the cover in the area of ​​the edge of the recess and engage in the foam body in a form-fitting manner. This creates tension between the cover and the foam body. Furthermore, both the cover and the collar are fixed relative to the foam body. The pins thus have a dual function: they secure the cover in the area of ​​an edge of the foam body recess and ensure the position of the collar, and preferably also the housing shell, relative to the foam body.

[0009] In a further embodiment of the invention, the locking pins are integrally molded onto the collar. In this embodiment, the locking pins are manufactured together with the collar of the housing shell, in particular by producing them from the same plastic material as the collar in a single-stage injection molding process. In the injection molding process, the locking pins are integrally molded onto the collar, preferably during the simultaneous production of the housing shell, provided that the housing shell integrally encompasses the collar.

[0010] In a further embodiment of the invention, the foam body is provided, in the area of ​​the edge of the receptacle, with a circumferential tensioning frame held within the foam body, which is covered by the cover. The collar of the housing shell is connected to the tensioning frame and covers the cover in the area of ​​the edge of the receptacle. The tensioning frame ensures that the housing shell is secured in the receptacle of the foam body when assembled. Furthermore, the cover is sandwiched between the collar and the tensioning frame by means of an edge region of a recess in the cover that surrounds the receptacle.

[0011] In a further embodiment of the invention, the cover is clamped between the collar and the tensioning frame. This achieves a force-fit securing of the edge area of ​​the cover's recess in the area of ​​the mounting.

[0012] In a further embodiment of the invention, the tensioning frame has openings for the collar's locking pins, and the locking pins penetrate the cover located between the tensioning frame and the collar. The cover located between the tensioning frame and the collar defines a circumferential edge region of a recess in the cover, which is aligned with a base surface for receiving the foam body.

[0013] In a further embodiment of the invention, the clamping frame is provided with mounting claws, each of which is integrally molded onto the clamping frame by means of a film hinge and pivotably arranged between a starting position projecting from the clamping frame towards a center and a functional position in which the claws are engaged in a wall of the foam body's receptacle. A solid-state hinge of any type can be considered a film hinge. This embodiment enables the mounting claws of the clamping frame to be automatically anchored in the wall of the foam body's receptacle as soon as the housing shell is inserted into the clamping frame from above.

[0014] In a further embodiment of the invention, the housing shell is provided with locking and / or plug-in profiles that interact with complementary locking and / or plug-in profiles of the mounting claws and / or the clamping frame to fix the housing shell in its state inserted into the receptacle of the foam body.

[0015] In a further embodiment of the invention, the housing shell is divided into an upper housing part having a collar and a lower housing part, wherein the lower housing part is embedded in the foam body and the upper housing part is connected to the cover by the collar being connected around its circumference to an edge of the cover in the area of ​​a recess in the cover for receiving it. The lower housing part is fixed in the recess of the foam body. The upper housing part is firmly connected to the cover, so that when the cover is pulled onto the foam body, the connection between the upper and lower housing parts inevitably secures and tensions the cover.

[0016] In a further embodiment of the invention, the upper and lower housing parts are joined together, in particular by bonding. Instead of bonding, a material-bonded connection can also be achieved by welding, in particular ultrasonic welding.

[0017] For the method of the type mentioned at the outset, in which a foam body is provided with a receptacle for a housing shell and in which the foam body is provided with a cover, the problem underlying the invention is solved by connecting a collar of the housing shell to the cover in an edge region of the receptacle. Furthermore, the method according to the invention achieves a fixation of the housing shell in the receptacle, in particular by frictional connection or by material bonding, preferably in the form of adhesive bonding.

[0018] In this embodiment of the method, pins are molded onto the collar. When the housing shell is inserted into the receptacle, these pins penetrate the cover and become embedded in the foam core. The pins pass through the edge of the cover recess in the receptacle area.

[0019] In a further embodiment of the invention, a clamping frame is molded into the foam body in the area of ​​the recess, and the collar of the housing shell is connected to the clamping frame when the housing shell is inserted into the recess, with the interposition of a circumferential edge of the cover. This results in a forced connection with the edge region of the recess in the cover when the housing shell is inserted. The clamping frame is preferably placed in a plastic foam mold in which the foam body is produced, so that the clamping frame is automatically formed during the foaming process.

[0020] In a further embodiment of the invention, mounting claws are molded onto the clamping frame. In their initial state, these claws project freely towards the center of the receptacle. When the housing shell is inserted into the receptacle, the claws are pressed downwards and outwards, thereby penetrating the walls of the foam body's receptacle. This enables particularly simple manufacturing of the backrest assembly, since inserting the housing shell from above inevitably secures both the housing shell relative to the clamping frame and fixes and tensions the edge region of the cover between the collar of the housing shell and the clamping frame.

[0021] In a further embodiment of the method, the housing shell locks onto the mounting claws on the outside as soon as it has reached its functional position inserted into the receptacle. Alternatively or additionally, in addition to locking the housing shell onto the mounting claws, locking the housing shell onto the clamping frame is also preferably provided.

[0022] In a further embodiment of the invention, the housing shell is manufactured as two separate components: an upper housing part with a collar and a trough-shaped lower housing part. The lower housing part is then embedded in the recess of the foam body, the upper housing part is connected to the cover, and the cover is pulled onto the foam body. The upper housing part is connected to an upper edge of the lower housing part in the area of ​​the recess. This connection is preferably achieved by bonding. The upper and lower housing parts either butt against each other or overlap. The respective contact surfaces are provided with a suitable adhesive film, resulting in the desired bond. The upper housing part is connected to the edge region of the cover around the recess in the cover.
