[0002] An armrest assembly for a vehicle seat structure is known from DE 10 2018 213 763 A1. This known armrest assembly has a support structure fixed to the vehicle in an assembled state, the support structure including a shaft profile fixed to the vehicle in the assembled state. Furthermore, this known armrest assembly has an armrest body with a carrier structure and a support device, wherein, by means of the support device, the armrest body is pivotally supported on the shaft profile about its longitudinal axis between a rest position and a supported position relative to the support structure. This known armrest assembly is provided for a central armrest arranged between two seats in a vehicle seat structure configured as a long seat. The shaft profile is covered at both ends by the vehicle seat structure in the assembled state. Summary of the Invention

[0003] The objective of this invention is to provide armrest assemblies, structural assemblies, and vehicle seat structures of the type mentioned at the beginning, which enable simplified assembly.

[0004] The task for the handrail assembly is achieved by holding the carrier structure pivotally (especially axially) at the support device about a longitudinal axis; and the free end section of the shaft profile has a non-rotationally symmetric (especially polygonal) cross-section, and the support device is axially inserted into the free end section, thereby enabling the support device to be form-fitted to the shaft profile about the longitudinal axis. The support device can be axially detachably connected to the shaft profile on one side. Therefore, the support device can be pulled out of the shaft profile along the longitudinal axis, for example for maintenance purposes, or can be inserted into the shaft profile from one side for assembling the handrail assembly. This results in particularly simple assembly. In particular, the support device can be pulled out of the shaft profile axially without removing the support structure from the vehicle and / or without removing other components of the handrail assembly. The free end of the shaft profile is preferably free in the assembled state of the support structure, i.e., extending outward as an axially blind end. Opposite to the free end axially, the support structure can be fixed or can be fixed to the structural components.

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

[0006] In one embodiment of the invention, the support device can be pre-assembled on the handrail body, particularly on the carrier structure. Here, in the pre-assembled state, the support device, together with the handrail body, can be inserted into or removed from the free end section. Advantageously, a structural assembly consisting of the handrail body and the support device pre-assembled on the handrail body can be provided. This results in particularly simple assembly of the handrail assembly. Furthermore, the entire structural assembly can be replaced in a particularly simple manner, for example, for maintenance purposes, especially without having to remove the support structure from the vehicle.

[0007] In another embodiment of the invention, the support device has a rotation stop element that is shaped-fittingly inserted into the free end section of the shaft profile about a longitudinal axis, wherein the handrail body has a stop device (particularly movable relative to the carrier structure) that rests against the rotation stop element in the supported position. This handrail assembly has proven to be particularly robust. With the movable stop device, the support position can be ergonomically adapted.

[0008] In another embodiment of the invention, the support device has at least one (especially bushing-shaped) support member that is shaped to fit into the free end section of the shaft profile about a longitudinal axis. The carrier structure has a support opening for each support member, in which the support member is rotatably received relative to the carrier structure. In particular, the support member has a radially projecting shoulder that serves as an axial stop for the carrier structure. This achieves particularly reliable support for the carrier structure.

[0009] In another embodiment of the invention, two support members are provided, which are fitted into the free end section of the shaft profile on both sides of the rotation stop element of the support device in a rotationally rigid manner. In particular, at least one of the support members and / or the rotation stop element has a positioning aid for orienting the at least one support member and the rotation stop element relative to each other. This multi-piece support device has proven to be particularly assembly-friendly. Especially for maintenance purposes, only one of the aforementioned components can be replaced, without having to replace the entire support device. The positioning aid ensures the correct rotational orientation of the support member and the rotation stop element relative to the longitudinal axis.

[0010] In another embodiment of the invention, the support device is detachably held in the carrier structure axially and radially relative to the longitudinal axis by means of a fixing device of the handrail assembly, wherein—alternatively or additionally—the support device is detachably held in the shaft profile axially by means of (especially the same) fixing device. The fixing device advantageously ensures that the components held together do not accidentally detach. If only a single fixing device is used to achieve the above function, a particularly small number of components is advantageously obtained. This can have a favorable effect on assembly costs.

[0011] In another embodiment of the invention, the fixing device has a resiliently deformable preload element, wherein the free end section has an engagement profile, and wherein a transversely resiliently deflectable engagement section (especially in a hook-like manner) of the preload element engages into the engagement profile to detachably hold the support device along the longitudinal axis at the shaft profile, particularly wherein the engagement section extends through the engagement profile into the profile interior space of the shaft profile. The engagement profile may be radially open. Preferably, the resiliently deflectable engagement section automatically deflects when the support device is inserted into the shaft profile so that it locks into the engagement profile once the engagement profile aligns with the engagement section (especially radially). Therefore, manual operation of the fixing device is not required for fixation.

[0012] In another embodiment of the invention, the internal space of the shaft profile is accessible along the longitudinal axis at the end, particularly to allow the connection between the support device and the shaft profile to be detached from the outside. Here, "from the outside" means that, to detach the connection, a tool can be guided from the external surroundings of the shaft profile into the internal space through an opening at the end of the shaft profile. This achieves, particularly easily, the removal of the support device along with the carrier structure from the shaft profile, wherein the support device preferably remains in its pre-assembled state at the carrier structure. The handrail body may have a cover detachably fixed to the carrier structure to cover the shaft profile at the end. This cover can be removed from the carrier structure to detach the connection from the outside.

[0013] In another embodiment of the invention, the armrest assembly has a friction ring arranged along a longitudinal axis, particularly clamped between the carrier structure and the support device. The friction ring advantageously generates defined friction between the carrier structure and the support device, preferably sufficient to hold the armrest body in any intermediate position between a rest position and a supported position. In particular, the armrest body can be frictionally held in its rest position.

[0014] In another embodiment of the invention, the handrail assembly has an elastically deformable compensation device for compensating for the axial clearance between the support device and the carrier structure. Specifically, the compensation device is integrally constructed at a fixing device for detachably holding the support device at the shaft profile and / or the carrier structure. Advantageously, this allows for minimizing or even completely eliminating the axial clearance between the support device and the carrier structure.

[0015] In another embodiment of the invention, the support device is held axially and radially at the shaft profile by means of the compensation device (especially by means of the preload generated by the compensation device). Advantageously, the axial and radial clearances of the support device relative to the shaft profile can therefore be kept low or even completely avoided by means of the compensation device.

[0016] In another embodiment of the invention, the support device has a receiving opening complementary to the shaft profile, into which a free end section of the shaft profile is inserted along the longitudinal axis, so as to shaped-fit the support device to the shaft profile about the longitudinal axis. This advantageously results in a particularly robust handrail assembly.

[0017] In another embodiment of the invention, the support member of the support device has (especially an integral) a preload section, which is deformable under axial preload generated by the shaft profile to compensate for axial clearance between the shaft profile and the support device. The preload section may be in contact with the end side of the shaft profile. This requires the support device to be arranged on the shaft profile without clearance.

[0018] For the structural assembly, the above-mentioned task can be achieved by: the carrier structure being pivotally held at the support device about a longitudinal axis; and the support device being coordinated with the free end section of the shaft profile, the free end section having a non-rotationally symmetric (especially polygonal) cross-section, and the support device being axially insertable into the free end section, thereby allowing the support device to be form-fitted with the shaft profile about a longitudinal axis. This structural assembly can be pre-assembled. The structural assembly according to the invention is provided for the handrail assembly according to the invention as described above. In particular, the support structure is not part of the structural assembly. The structural assembly may include all components of the handrail assembly except for the support device. Under this provision, the above-mentioned advantages of the handrail assembly according to the invention also apply to the structural assembly according to the invention for such handrail assembly.

[0019] Suitably, the armrest assembly can be configured as a side armrest assembly, wherein the aforementioned structural assembly can be pulled out to one side from the support structure or from the shaft profile, or conversely, can be axially inserted into the shaft profile. Such a side armrest assembly is (especially only) provided for mounting on one side of a vehicle seat structure (especially in the form of a single seat).

[0020] For vehicle seat structures, the aforementioned task is achieved by providing an armrest assembly according to the invention as described above. The vehicle seat structure is configured for use in vehicles, particularly motor vehicles, and preferably passenger cars. The vehicle seat structure includes a structural member from which the armrest body is pivotally movable between a rest position and a supported position. A support structure for the armrest assembly can be fixed to the structural member. The structural member can be fixed to the vehicle. The vehicle seat structure is preferably constructed as a single seat.

[0021] Other advantages and features of the invention will become apparent from the claims and from the following description of preferred embodiments of the invention, illustrated with reference to the accompanying drawings. Here, the same reference numerals refer to the same or similar or functionally identical components.

[0022] It goes without saying that, without departing from the scope of the invention, the features previously mentioned and to be described below can be used not only in the corresponding combinations given, but also in other combinations or individually. Attached Figure Description

[0023] Figure 1 A schematic perspective view illustrates one embodiment of a vehicle seat structure according to the invention, the vehicle seat structure having an armrest assembly according to the invention, the armrest assembly having structural assemblies according to the invention; Figure 2 Schematably illustrated using a perspective exploded diagram based on Figure 2 Armrest components; and Figure 3 A schematic longitudinal section along the longitudinal axis is shown according to Figure 1 and Figure 2 The handrail components. Detailed Implementation

[0024] Vehicle 200 according to Figure 1 The vehicle 200 includes a vehicle seat structure 100. The vehicle 200 may be a motor vehicle, such as a passenger car. The vehicle seat structure 100 can exist as a single seat, for example, as a driver's seat or a front passenger seat. An armrest assembly 1 is arranged at at least one outer wing of the backrest assembly of the vehicle seat structure 100. Here, the backrest assembly can constitute a structural component 101 of the vehicle seat structure 100.

[0025] The armrest assembly 1 has an armrest body 4, which is pivotable relative to the structural member 101 between a rest position and a supported position. In the rest position, the armrest body 4 extends along an extension of the structural member 101, for example, substantially along the direction of gravity. In contrast, in its supported position, the armrest body 4 extends laterally to the extension of the structural member 101, for example, at an angle to the direction of gravity, particularly perpendicularly. In other words, the armrest body 4 can fold upward from its supported position to its rest position, for example, to make it easier for passengers of the vehicle 200 to sit on the seat surface of the vehicle seat structure 100. In the supported position, the armrest body 4 can support the passenger's arm.

[0026] The armrest assembly 1 has a support structure 2. In its assembled state (in which the support structure 2 is, for example, assembled at structural component 101), the support structure 2 is fixed to the vehicle. Accordingly, the structural component 101 of the vehicle seat structure 100 can be fixed to the vehicle. The support structure 2 has a shaft profile 3, which is fixed to the vehicle in its assembled state. The armrest body 4 of the armrest assembly 1, as mentioned above, has a carrier structure 5. The pad element of the armrest assembly 1 can be placed on the carrier structure 5.

[0027] Furthermore, the handrail assembly 1 has a support device 6. The handrail body 4 is supported on the shaft profile 3 by means of the support device 6. Here, the handrail body 4 is supported on the shaft profile 3 such that the handrail body 4 can pivot about the longitudinal axis L of the shaft profile 3 relative to the support structure 2 between a rest position and a supported position. The support device 6 can be detachably held on the carrier structure 5 axially and radially relative to the longitudinal axis L. Therefore, the support device 6 can be substantially immovable relative to the carrier structure 5 along the longitudinal axis L and transversely to the longitudinal axis L. Here, the carrier structure 5 is pivotally held on the support device 6 about the longitudinal axis L. Sliding contact can exist between the carrier structure 5 and the support device 6. The shaft profile 3 has a free end section 7. Opposite to the free end section 7, the shaft profile 3 can be fixed to the structural member 101 by means of the flange of the support structure 2. The free end section 7 of the shaft profile 3 has a non-rotationally symmetric cross section. The cross section is oriented perpendicular to the longitudinal axis L. The cross section can be constructed as a polygon. Currently, the cross section is constructed as a substantially square. "Basically" here means that the cross-section of the polygon can be realized with rounded or beveled corners. It goes without saying that other non-rotationally symmetric cross-sections, such as elliptical or other non-circular cross-sections, are also conceivable. For example, a non-rotationally symmetric cross-section can be constructed as non-circular. The support device 6 is axially inserted into the free end section 7. The support device 6 is detachably connected to the shaft profile 3 about the longitudinal axis L in a form-fitting manner. Here, the support device 6 is rotatably rigidly connected to the shaft profile 3. The support device 6 and the shaft profile 3 can be constructed with a form-fitting plug-in connection structure, by means of which the support device 6 is prevented from rotating relative to the shaft profile 3 about the longitudinal axis L in a form-fitting manner.

[0028] For example, the support device 6 can be pre-assembled onto the armrest body 4. The support device 6 can also be pre-assembled onto the carrier structure 5. In the pre-assembled state, the support device 6, together with the armrest body 4, can be inserted into the free end section 7. From the inserted state, the support device 6, together with the armrest body 4, can be removed from the free end section 7. Therefore, in the pre-assembled state, the support device 6 and the armrest body 4 constitute a structural assembly according to the invention, which can be pre-assembled onto the support structure 2. Here, the structural assembly can then be removed from the support structure 2 (e.g., for maintenance purposes) without having to disassemble it. In particular, this assembly and / or disassembly of the assembled structural assembly can be performed not only when the support structure 2 is assembled onto the structural component 101 of the vehicle seat structure 100, but also when the support structure 2 is not fixed to the vehicle seat structure 100.

[0029] Currently, the support device 6 has a rotation stop element 8. The rotation stop element 8 is shaped-fitted into the free end section 7 of the shaft profile 3 around the longitudinal axis L. The handrail body 4 has a stop device 9. The stop device 9 is currently movable relative to the carrier structure 5. In the supported position, the stop device 9 rests against the rotation stop element 8. Conversely, in the rest position, the stop device 9 can be arranged spaced apart from the rotation stop element 8. By displacing the stop device 9 relative to the carrier structure 5, the support position can be adjusted relative to the rest position. Currently, the stop device 9 has a claw-shaped region with two protrusions on either side of the rotation stop element 8 along the longitudinal axis L. The rotation stop element 8 currently has a base from which a fortsatz protrudes radially. This fortsatz can form a true stop for the supported position. When the handrail body 4 is in its supported position, this fortsatz can contact the connecting section between the two protrusions in the claw-shaped region.

[0030] For example, the support device 6 has at least one support member 10. The support member 10 may be configured as a bushing. The support member 10 is shaped-fitted into the free end section 7 of the shaft profile 3 about the longitudinal axis L. Here, the carrier structure 5 has a support opening 11 for each support member 2, in which the support member 10 is rotatably received relative to the carrier structure 5. A sliding contact may be established between the support member 10 and the support opening 11. Here, the support member 10 may have a radially projecting shoulder 12, which is configured as an axial stop for the carrier structure 5. The shoulder 12 may be configured to be annularly surrounding, with or without an interruption. Currently, there are two support members 10 and two associated support openings 11. At least one of the support members 10 may be axially detachably fastened to the carrier structure 5 or the associated support opening 11 by means of a locking ring 23.

[0031] In the current embodiment, two support members 10 are shaped-fitted into the free end section 7 of the shaft profile 3 on both sides of the rotation stop element 8 along the longitudinal direction L. At least one of the support members 10 and, alternatively or additionally, the rotation stop element 8 may have a positioning aid 13 for orienting the at least one support member 10 and the rotation stop element 8 relative to each other. Currently, each of the two support members 10 has at least one such positioning aid 13 in the form of a protrusion on its end side facing the rotation stop element 8, which is received in a complementary gap on the end side of the rotation stop element 8. In this way, the rotational orientation of the support members 10 and the rotation stop element 8 can be ensured, especially before the support members 10 and the rotation stop element 8 are inserted into the free end section 7 of the shaft profile 3.

[0032] The carrier structure 5 may have a radial clearance, which is arranged between the two existing support openings 11. This radial clearance allows for the... Figure 2 and Figure 3 The support member 10 shown on the left is positioned at the relevant support opening 11. The rotation stop element 8 can also be positioned at the carrier structure 5 via a radial clearance. Figure 2 and Figure 3 The support member 10 shown on the right is arranged externally along the longitudinal direction L at the relevant support opening 11, and is then axially detachably fixed to the carrier structure 5 by means of a locking ring 23. When the support member 10 and the rotation stop element 8 are arranged in this manner, i.e., in the pre-assembled structural assembly mentioned above, the support member 10 and the rotation stop element 8 can be held at the carrier structure 5 in the correct orientation for insertion into the shaft profile 3 by means of the positioning aid 13.

[0033] The handrail assembly 1 currently has a fixing device 14, by means of which the support device 6 can be detachably held in the carrier structure 5 axially and radially relative to the longitudinal axis L. The support member 10 and the rotation stop element 8 can be detachably held in the carrier structure 5 in the previously described arrangement by means of the fixing device 14. Furthermore, the support device 6 can be detachably held in the shaft profile 3 axially by means of the fixing device 14. In particular, the fixing device 14 for holding the support device 6 in the carrier structure 5 and for holding the support device 6 in the shaft profile 3 is the same fixing device 14.

[0034] The fixing device 14 is currently constructed in a clip-like manner. Here, the fixing device 14 has a preload element 15 that is elastically deformable. The free end section 7 of the shaft profile 3 has an engagement profile 16. Currently, the engagement profile 16 is constructed as a through-hole, by means of which the internal space 18 of the shaft profile 3 can be opened outward. The preload element 15 has an engagement section 17 that can elastically deflect laterally to the longitudinal axis L. The engagement section 17 (particularly radially) engages into the engagement profile 16 so as to detachably hold the support device 6 at the shaft profile 3 along the longitudinal axis L. For example, the engagement section 17 engages into the engagement profile 16 in a hook-like manner. The engagement section 17 can extend into the internal space 17 of the shaft profile 3 through the engagement profile 16. The preload element 17 can be fixed to one of the support members 10 at the end of the preload element 17 opposite to the engagement section 17. For example, the end of the preload element 17 is inserted, in particular pressed, into the receiving recess provided for this purpose in the associated support member 10. For example, the engagement section 17 is constructed such that when the support device 6 is inserted into the free end section 7 of the shaft profile 3, the engagement section 17 deflects radially through the end section 7, and automatically springs back radially once the engagement section 17 intersects with the engagement profile 16, so as to engage into the engagement profile 16.

[0035] The internal space 18 of the shaft profile 3 can be approached at the end side along the longitudinal axis L, thereby allowing the connection between the support device 6 and the shaft profile 3 to be disengaged from the outside via the internal space 18. For example, the engagement section 17 can be radially displaced through the end opening of the shaft profile 3 using a slender tool, such as a screwdriver, in order to disengage the engagement of the engagement section 17.

[0036] Currently, the handrail assembly also has a friction ring 19, which is arranged along the longitudinal axis L between the carrier structure 5 and the support device 6. For example, the friction ring 19 is clamped between the carrier structure 5 and the support device 6, especially to generate a defined friction between the carrier structure 5 and the support device 6. This clamping can be achieved by means of an elastically deformable compensation device 20 of the handrail assembly 1. The elastically deformable compensation device 20 is used to compensate for the axial clearance between the support device 6 and the carrier structure 5. As is currently the case, the compensation device 20 can be integrally constructed at the fixing device 14 for detachably holding the support device 6 at the shaft profile 3 and / or the carrier structure 5. Currently, the compensation device 20 is designed in the form of a wave spring that protrudes radially outward from the engagement section 17. For example, the support device 6 is held axially and radially at the shaft profile 3 by means of the compensation device 20 (especially by means of the preload generated by the compensation device 20). Currently, the preload generated by the compensation device 20 ensures Figure 2 and Figure 3The support member 10 shown on the left side presses against the carrier structure 5 with its radial protrusion 12, while the rotation stop element 8 presses against it in the opposite direction. Figure 2 and Figure 3 The support member 10 is shown on the right side. Here, the right-side support member 10 is further supported axially by means of a locking ring 23. The positioning aid 13 here holds the rotation stop element 8 radially and in the correct rotational orientation between the two support members 10. In this way, after manipulating the engagement section 17, the shaft profile 3 can be removed from the support device 6 along the longitudinal axis L, without the individual components of the support device 6 losing their connection with the carrier structure 5, especially their axial and radial fixation. Therefore, the structural assembly can remain in its assembled or pre-assembled state.

[0037] The support device 6 currently has a receiving opening 21 that is complementary to the shaft profile 3. Here, the two support members 10 and the rotation stop element 8 each have an axial section of the receiving opening 21. These sections are arranged in a common row along the longitudinal axis L. The free end section 7 of the shaft profile 3 is inserted into the receiving opening 21 along the longitudinal axis L (especially detachably) so as to connect the support device 6 to the shaft profile 3 in a form-fitting manner around the longitudinal axis L.

[0038] For example, at least one support member 10 of the support device 6 has (especially an integral) a preload section 22. This preload section 22 is used to compensate for axial clearance between the shaft profile 3 and the support device 6. Here, the preload section 22 can deform under the influence of an axial preload force generated by the shaft profile 3 to compensate for the axial clearance. Currently, Figure 2 and Figure 3 The support member 10 shown on the left is configured with this integral preload section 22. The integral preload section 22 ensures that the engagement profile 16 of the shaft profile 3 is in clearance-free contact with the compensation device 20 along the longitudinal axis L. The integral preload section 22 can contact the end side of the free end section 7 of the shaft profile 3.
