Description

[0001] The invention relates to an armrest arrangement for a vehicle seat structure, comprising a support structure which is fixed to the vehicle in the assembled state and which has an axle profile which is fixed to the vehicle in the assembled state, an armrest body with a carrier structure, and a bearing device by means of which the armrest body is mounted on the axle profile so as to be pivotable about a longitudinal axis of the axle profile relative to the support structure between a rest position and a support position. The invention also relates to an assembly for such an armrest arrangement, wherein the assembly has an armrest body with a carrier structure, and a bearing device by means of which the armrest body is mounted on an axle profile so as to be pivotable about a longitudinal axis of the axle profile between a rest position and a support position. The invention further relates to a vehicle seat structure with such an armrest arrangement.

[0002] An armrest arrangement for a vehicle seat structure is known from DE 10 2018 213 763 A1. The known armrest arrangement has a support structure that is fixed to the vehicle in the assembled state and comprises an axle profile that is fixed to the vehicle in the assembled state. Furthermore, the known armrest arrangement has an armrest body with a support structure and a bearing device, wherein the armrest body is pivotally mounted on the axle profile relative to the support structure between a rest position and a support position about a longitudinal axis of the axle profile by means of the bearing device. The known armrest arrangement is provided for a center armrest that is arranged between two seats of a vehicle seat structure designed as a bench seat. In the assembled state, the axle profile is covered at both ends by the vehicle seat structure.

[0003] The object of the invention is to provide an armrest arrangement, an assembly and a vehicle seat structure of the type mentioned at the outset which enable simplified assembly.

[0004] This object is achieved for the armrest arrangement in that the support structure is held on the bearing device so as to be pivotable about the longitudinal axis, in particular axially, and in that a free end section of the axle profile has a polygonal cross-section and the bearing device is axially mounted on the free end section, such that the bearing device is positively connected to the axle profile about the longitudinal axis. The bearing device can be connected to the axle profile on one side in an axially detachable manner. Thus, the bearing device can be pulled off the axle profile along the longitudinal axis, for example for maintenance purposes, or can be mounted on the axle profile from one side for assembling the armrest arrangement. This results in particularly simple assembly.In particular, the bearing device can be axially removed from the axle profile without having to dismantle the support structure from the vehicle and / or without having to remove other components of the armrest assembly. The free end of the axle profile is preferably free when the support structure is mounted, i.e., it projects axially outward with a blind end. Axially opposite the free end, the support structure can be or is attached to a structural component.

[0005] Unless otherwise stated, the terms "axial" and "radial" in this context refer to the longitudinal axis of the axle profile. Radial can mean "perpendicular to the longitudinal axis." Axial can mean "along the longitudinal axis."

[0006] In one embodiment of the invention, the bearing device can be pre-assembled on the armrest body, in particular on the support structure. In this case, the bearing device, in its pre-assembled state, can be plugged onto the free end section together with the armrest body or removed from the free end section. This advantageously provides an assembly comprising the armrest body and the pre-assembled bearing device. This results in particularly simple assembly of the armrest arrangement. Furthermore, the entire assembly can be replaced in a particularly simple manner, for example, for maintenance purposes, in particular without having to dismantle the support structure from the vehicle.

[0007] In a further embodiment of the invention, the bearing device comprises a rotation stop element that is positively attached to the free end section of the axle profile around the longitudinal axis. The armrest body comprises a stop device, which is adjustable in particular relative to the support structure. The stop device is positioned against the rotation stop element in the support position. Such an armrest arrangement proves to be particularly robust. With an adjustable stop device, the support position can be ergonomically adjusted.

[0008] In a further embodiment of the invention, the bearing device comprises at least one, in particular bush-shaped, bearing piece, which is positively mounted on the free end section of the axle profile around the longitudinal axis. The support structure has a bearing opening for each bearing piece, in which the bearing piece is rotatably received relative to the support structure. In particular, the bearing piece has a radially projecting shoulder that forms an axial stop for the support structure. This enables particularly reliable mounting of the support structure.

[0009] In a further embodiment of the invention, two bearing pieces are provided which are mounted on both sides of a rotation stop element of the bearing device in a form-fitting, torsionally rigid manner on the free end section of the axle profile, in particular wherein at least one of the bearing pieces and / or the rotation stop element has a positioning aid for aligning the at least one bearing piece and the rotation stop element relative to one another. Such a multi-part bearing device proves to be particularly easy to install. In particular, only one of the aforementioned components can be exchanged for maintenance purposes, instead of having to replace the entire bearing device. The positioning aid can ensure correct rotational alignment of the bearing pieces and the rotation stop element with respect to the longitudinal axis.

[0010] In a further embodiment of the invention, the bearing device is releasably held axially and radially on the support structure with respect to the longitudinal axis by means of a fastening device of the armrest arrangement, wherein—alternatively or additionally—the bearing device is releasably held axially on the axle profile by means of the fastening device, in particular by means of the same fastening device. The fastening device advantageously ensures that the components held together do not accidentally become detached. Using only a single fastening device to fulfill the above functions advantageously results in a particularly low number of parts. This can have a beneficial effect on assembly effort.

[0011] In a further embodiment of the invention, the fastening device has an elastically deformable prestressing element, wherein the free end portion has an engagement contour, and wherein an engagement portion of the prestressing element that can be elastically deflected transversely to the longitudinal axis engages in the engagement contour, in particular in the manner of a snap hook, in order to releasably hold the bearing device on the axle profile along the longitudinal axis, in particular wherein the engagement portion projects through the engagement contour into a profile interior of the axle profile. The engagement contour can be radially recessed. Preferably, the elastically deflectable engagement portion is automatically deflected when the bearing device is plugged onto the axle profile, in order to then lock with the engagement contour as soon as the engagement contour is aligned with the engagement portion, in particular radially. Manual actuation of the fastening device is therefore not required for fastening.

[0012] In a further embodiment of the invention, a profile interior of the axle profile is accessible from the front along the longitudinal axis, in particular in order to release a connection between the bearing device and the axle profile from the outside. “From the outside” means that in order to release the connection, a tool can be guided from an external area of ​​the axle profile through a front opening in the axle profile into the profile interior. This enables particularly simple disassembly of the bearing device together with the support structure from the axle profile, wherein the bearing device can preferably remain on the support structure in its pre-assembled state. The armrest body can have a cover which is detachably attached to the support structure in order to cover the axle profile at the front. In order to release the connection from the outside, this cover can be removed from the support structure.

[0013] In a further embodiment of the invention, the armrest assembly comprises a friction ring arranged, in particular clamped, along the longitudinal axis between the support structure and the bearing device. The friction ring advantageously allows a defined friction to be generated between the support structure and the bearing device, which is preferably sufficient to hold the armrest body in any intermediate position between the rest position and the support position. In particular, the armrest body can be held in its rest position by frictional engagement.

[0014] In a further embodiment of the invention, the armrest arrangement comprises an elastically deformable compensation device for compensating for axial play between the bearing device and the support structure, in particular wherein the compensation device is integrally formed on a fastening device for releasably holding the bearing device to the axle profile and / or to the support structure. Thus, axial play between the bearing device and the support structure can advantageously be minimized or even completely eliminated.

[0015] In a further embodiment of the invention, the bearing device is held axially and radially to the axle profile by means of the compensating device, in particular by means of a preload force generated by the compensating device. Thus, the compensating device advantageously allows axial and radial play of the bearing device relative to the axle profile to be minimized or even completely eliminated.

[0016] In a further embodiment of the invention, the bearing device has a receiving opening complementary to the axle profile, into which the free end section of the axle profile is releasably inserted along the longitudinal axis to form-fit the bearing device to the axle profile around the longitudinal axis. This advantageously results in a particularly robust armrest arrangement.

[0017] In a further embodiment of the invention, a bearing piece of the bearing device has a preload section, in particular an integral one, which is deformable by means of the axle profile to compensate for axial play between the axle profile and the bearing device, generating an axial preload force. The preload section can be in contact with an end face of the axle profile. This promotes the play-free arrangement of the bearing device on the axle profile.

[0018] For the assembly, the above-mentioned object is achieved in that the support structure is held on the bearing device so as to be pivotable about the longitudinal axis, and in that the bearing device is matched to a free end section of the axle profile with a polygonal cross-section and the bearing device can be axially plugged onto the free end section so that the bearing device can be positively connected to the axle profile about the longitudinal axis. The assembly can be pre-assembled. The assembly according to the invention is provided for an armrest arrangement according to the invention as described above. In particular, the support structure is not a component of the assembly. The assembly can comprise all components of the armrest arrangement except for the support device. Under this proviso, the aforementioned advantages of the armrest arrangement according to the invention also apply to the assembly according to the invention for such an armrest arrangement.

[0019] The armrest arrangement can expediently form a side armrest arrangement, wherein the above-mentioned assembly can be removed from the support structure or the axle profile to one side or, conversely, can be axially attached to the axle profile. Such a side armrest arrangement is designed, in particular exclusively, for mounting on one side of a vehicle seat structure, in particular in the form of an individual seat.

[0020] For the vehicle seat structure, the above-mentioned object is achieved in that the vehicle seat structure is provided with an armrest arrangement according to the invention, as described above. The vehicle seat structure is intended for use in a vehicle, in particular in a motor vehicle, preferably in a passenger car. The vehicle seat structure comprises a structural part, relative to which the armrest body is pivotally movable between its rest position and its support position. The support structure of the armrest arrangement can be fastened to the structural part. The structural part can be fixed to the vehicle. The vehicle seat structure is preferably designed as an individual seat.

[0021] Further advantages and features of the invention will become apparent from the claims and the following description of a preferred embodiment of the invention, which is illustrated with reference to the drawings. Like reference numerals refer to like, similar, or functionally identical components.

[0022] It is understood that the features mentioned above and those to be explained below can be used not only in the combination specified in each case, but also in other combinations or on their own, without departing from the scope of the present invention. Fig. 1 shows a schematic perspective view of an embodiment of a vehicle seat structure according to the invention with an armrest arrangement designed according to the invention, which has an assembly designed according to the invention, Fig. 2 in perspective exploded view schematically the armrest arrangement according to Fig. 1, and Fig. 3 in schematic longitudinal section along a longitudinal axis the armrest arrangement according to the Fig. 1 and Fig. 2.

[0023] A vehicle 200 has according to Fig. 1, a vehicle seat structure 100 is shown. The vehicle 200 can be a motor vehicle, for example, in the form of a passenger car. The vehicle seat structure 100 can be in the form of a single seat, for example, as a driver's seat or as a passenger seat. An armrest arrangement 1 is arranged on at least one outer flank of a backrest arrangement of the vehicle seat structure 100. The backrest arrangement can form a structural part 101 of the vehicle seat structure 100.

[0024] The armrest arrangement 1 has an armrest body 4, which is pivotable between a rest position and a support position relative to the structural part 101. In its rest position, the armrest body 4 can extend along an extension of the structural part 101, for example, substantially along a direction of gravity. In contrast, in its support position, the armrest body 4 can extend transversely to the extension of the structural part 101, for example, at an angle, in particular perpendicular, to the direction of gravity. In other words: from its support position, the armrest body 4 can be folded upward into its rest position, for example, to facilitate a passenger of the vehicle 200 taking a seat on a seat surface of the vehicle seat structure 100. In the support position, the armrest body 4 can support an arm of the passenger.

[0025] The armrest assembly 1 has a support structure 2. In an assembled state of the support structure 2, in which the support structure 2 is mounted, for example, on the structural part 101, the support structure 2 is fixed to the vehicle. Accordingly, the structural part 101 of the vehicle seat structure 100 can be fixed to the vehicle. The support structure 2 has an axle profile 3, which is fixed to the vehicle in the assembled state of the support structure 2. The previously mentioned armrest body 4 of the armrest assembly 1 has a support structure 5. A cushion element of the armrest assembly 1 can be attached to the support structure 5.

[0026] The armrest arrangement 1 further comprises a bearing device 6. The armrest body 4 is mounted on the axle profile 3 by means of the bearing device 6. The armrest body 4 is mounted on the axle profile 3 in such a way that the armrest body 4 is pivotally movable relative to the support structure 2 between the rest position and the support position about a longitudinal axis L of the axle profile 3. The bearing device 6 can be releasably held on the support structure 5 axially and radially with respect to the longitudinal axis L. The bearing device 3 can therefore be essentially immovable relative to the support structure 5 along the longitudinal axis L and transversely to the longitudinal axis L. The support structure 5 is held on the bearing device 6 so as to be pivotable about the longitudinal axis L. Sliding contact can exist between the support structure 5 and the bearing device 6. The axle profile 3 has a free end section 7.Opposite the free end section 7, the axle profile 3 can be fastened to the structural part 101 by means of a flange of the support structure 2. The free end section 7 of the axle profile 3 has a rotationally asymmetrical cross-section. The cross-section is oriented perpendicular to the longitudinal axis L. According to the invention, the cross-section is polygonal. In the present case, the cross-section is essentially square. “Essentially” refers to the fact that the polygonal cross-section can be realized with rounded or beveled corners. It is understood that other rotationally asymmetrical cross-sections are also conceivable, for example elliptical or other non-circular cross-sections. The rotationally asymmetrical cross-section is, for example, not circular. The bearing device 6 is axially slipped onto the free end section 7. The bearing device 6 is detachably connected to the axle profile 3 in a form-fitting manner about the longitudinal axis L.The bearing device 6 can be connected to the axle profile 3 in a rotationally rigid manner. The bearing device 6 and the axle profile 3 can form a positive plug connection, by means of which rotation of the bearing device 6 relative to the axle profile 3 about the longitudinal axis L is positively prevented.

[0027] For example, the bearing device 6 can be pre-assembled on the armrest body 4. The bearing device 6 can be pre-assembled on the support structure 5. In a pre-assembled state of the bearing device 6, the bearing device 6 together with the armrest body 4 can be plugged onto the free end section 7. Starting from the plugged-on state, the bearing device 6 together with the armrest body 4 can be removed again from the free end section 7. In the pre-assembled state, the bearing device 6 and the armrest body 4 thus form an assembly according to the invention, which can be attached in a pre-assembled manner to the support structure 2. The assembly can then be removed from the support structure 2 again, for example for maintenance purposes, without having to disassemble the assembly.In particular, such assembly and / or disassembly of the assembled assembly can take place both when the support structure 2 is mounted on the structural part 101 of the vehicle seat structure 100 and when the support structure 2 is not attached to the vehicle seat structure 100.

[0028] In the present case, the bearing device 6 has a rotation stop element 8. The rotation stop element 8 is positively attached to the free end section 7 of the axle profile 3 about the longitudinal axis L. The armrest body 4 has a stop device 9. The stop device 9 is adjustable relative to the support structure 5. In the support position, the stop device 9 is applied to the rotation stop element 8. Conversely, the stop device 9 can be arranged at a distance from the rotation stop element 8 in the rest position. By adjusting the stop device 9 relative to the support structure 5, the support position can be adjusted relative to the rest position. In the present case, the stop device 9 has a claw-shaped region with two projections that flank the rotation stop element 8 on both sides along the longitudinal axis L. The rotation stop element 8 has a base body from which an extension protrudes radially.This extension can form the actual stop for the support position. The extension can be in contact with a connecting section between the two projections of the claw-shaped area when the armrest body 4 is in its support position.

[0029] The bearing device 4 has, for example, at least one bearing piece 10. The bearing piece 10 can be bush-shaped. The bearing piece 10 is positively placed on the free end section 7 of the axle profile 3 about the longitudinal axis L. The support structure 5 has a bearing opening 11 for each bearing piece 2, in which the bearing piece 10 is received so as to be rotatable relative to the support structure 5. A sliding contact can be formed between the bearing piece 10 and the bearing opening 11. The bearing piece 10 can have a radially projecting shoulder 12 which forms an axial stop for the support structure 5. The shoulder 12 can be annularly circumferential, with interruptions or without interruptions. In the present case, there are two bearing pieces 10 and two associated bearing openings 11. At least one of the bearing pieces 10 can be axially attached to the support structure 5 orbe releasably fixed in the corresponding bearing opening 11.

[0030] The two bearing pieces 10 present in the present embodiment are positively fitted along the longitudinal direction L on both sides of the rotation stop element 8 onto the free end section 7 of the axle profile 3 around the longitudinal axis L. At least one of the bearing pieces 10 and - alternatively or additionally - the rotation stop element 8 can have a positioning aid 13 for aligning the at least one bearing piece 10 and the rotation stop element 8 relative to one another. In the present case, the two bearing pieces 10 each have at least one such positioning aid 13 in the form of a projection on their end faces facing the rotation stop element 8, which is received in complementary recesses on the end faces of the rotation stop element 8.In this way, a rotational alignment of the bearing pieces 10 and the rotation stop element 8 can be ensured, in particular before the bearing pieces 10 and the rotation stop element 8 are placed on the free end section 7 of the axle profile 3.

[0031] The support structure 5 can have a radial recess which is arranged between the two bearing openings 11. Via this radial recess, the Fig. 2 and Fig. 3, the bearing piece 10 shown on the left can be attached to the corresponding bearing opening 11. The rotation stop element 8 can also be positioned via the radial recess on the support structure 5. The Fig. 2 and Fig. 3, the bearing piece 10 shown on the right is arranged from the outside along the longitudinal direction L at the associated bearing opening 11 and then releasably fastened axially to the support structure 5 by means of a retaining ring 23. With a corresponding arrangement of the bearing pieces 10 and the rotation stop element 8, i.e., in the above-mentioned pre-assembled assembly, the bearing pieces 10 and the rotation stop element 8 can be held on the support structure 5 by means of the positioning aids 13 in the correct alignment for attachment to the axle profile 3.

[0032] The armrest arrangement 1 in the present case has a fastening device 14, by means of which the bearing device 6 is releasably held axially and radially on the support structure 5 with respect to the longitudinal axis L. By means of the fastening device 14, the bearing pieces 10 and the rotation stop element 8 can be releasably held on the support structure 5 in the arrangement described above. In addition, the bearing device 6 can be releasably held axially on the axle profile 3 by means of the fastening device 14. In particular, the fastening device 14 for holding the bearing device 6 to the support structure 5 and for holding the bearing device 6 to the axle profile 3 are one and the same fastening device 14.

[0033] The fastening device 14 is in the present case designed like a clamp. The fastening device 14 has an elastically deformable prestressing element 15. The free end section 7 of the axle profile 3 has an engagement contour 16. In the present case, the engagement contour 16 is designed as an opening, by means of which a profile interior 18 of the axle profile 3 is open to the outside. The prestressing element 15 has an engagement section 17 which is elastically deflectable transversely to the longitudinal axis L. The engagement section 17 engages, in particular radially, in the engagement contour 16 in order to releasably hold the bearing device 6 on the axle profile 3 along the longitudinal axis L. For example, the engagement section 17 engages the engagement contour 16 like a snap hook. The engagement section 17 can protrude through the engagement contour 16 into the profile interior 17 of the axle profile 3.The preload element 17 can be fastened to one of the bearing pieces 10 at an end of the preload element 17 facing away from the engagement section 17. For example, this end of the preload element 17 is inserted, in particular pressed, into a receiving recess provided for this purpose in the respective bearing piece 10. The engagement section 17 is designed, for example, such that when the bearing device 6 is plugged onto the free end section 7 of the axle profile 3, the engagement section 17 is radially deflected by the end section 7 and, as soon as the engagement section 17 overlaps the engagement contour 16, automatically springs back radially in order to engage with the engagement contour 16.

[0034] The profile interior 18 of the axle profile 3 is accessible, for example, along the longitudinal axis L at the front, so that a connection between the bearing device 6 and the axle profile 3 can be released from the outside via the profile interior 18. For example, the engagement section 17 can be radially adjusted through a front opening of the axle profile 3 using an elongated tool, for example a screwdriver, in order to release the engagement of the engagement section 17.

[0035] In the present case, the armrest arrangement also has a friction ring 19 which is arranged along the longitudinal axis L between the support structure 5 and the bearing device 6.

[0036] For example, the friction ring 19 is clamped between the support structure 5 and the bearing device 6, in particular to generate a defined friction between the support structure 5 and the bearing device 6. This clamping can be achieved by means of an elastically deformable compensation device 20 of the armrest arrangement 1. The elastically deformable compensation device 20 serves to compensate for any axial play between the bearing device 6 and the support structure 5. As in the present case, the compensation device 20 can be formed integrally on the fastening device 14 for releasably holding the bearing device 6 on the axle profile 3 and / or on the support structure 5. In the present case, the compensation device 20 is designed in the manner of a wave spring that projects radially outward from the engagement portion 17.For example, the bearing device 6 is held axially and radially on the axle profile 3 by means of the compensating device 20, in particular by means of a preload force generated by the compensating device 20. In the present case, this preload force generated by the compensating device 20 ensures that the... Fig. 2 and Fig. 3 left shown bearing piece 10 with its radial projection 12 is pressed against the support structure 5 and the rotation stop element 8 opposite to that against the Fig. 2 and Fig. 3 bearing piece 10 shown on the right. This right-hand bearing piece 10 is again axially supported by the retaining ring 23. The positioning aids 13 can hold the rotation stop element 8 radially between the two bearing pieces 10 and in the correct rotational alignment. In this way, after actuating the engagement section 17, the axle profile 3 can be removed from the bearing device 6 along the longitudinal axis L without the individual components of the bearing device 6 losing their connection, in particular their axial and radial fastening, to the support structure 5. The assembly can therefore remain in its assembled or pre-assembled state.

[0037] In this case, the bearing device 6 has a receiving opening 21 that is complementary to the axle profile 3. The two bearing pieces 10 and the rotation stop element 8 each have an axial section of this receiving opening 21. These sections are arranged in a common alignment along the longitudinal axis L. The free end section 7 of the axle profile 3 is inserted, in particular detachably, into the receiving opening 21 along the longitudinal axis L in order to positively connect the bearing device 6 to the axle profile 3 around the longitudinal axis L.

[0038] For example, at least one bearing piece 10 of the bearing device 6 has a, in particular integral, preloading section 22. This preloading section 22 serves to compensate for an axial play between the axle profile 3 and the bearing device 6. The preloading section 22 is deformable by means of the axle profile 3 to compensate for the axial play by generating an axial preload force. In the present case, the Fig. 2 and Fig. 3, the bearing piece 10 shown on the left is formed with such an integral preloading section 22. The integral preloading section 22 can ensure that the engagement contour 16 of the axle profile 3 is in play-free contact with the compensation device 20 along the longitudinal axis L. The integral preloading section 22 can be in contact with an end face of the free end section 7 of the axle profile 3.
