Abstract

A vehicle seat is provided. The vehicle seat comprises construction elements that are movable relative to one another and at least one force transmission element which transmits activation forces and/or stress forces that result from the use of the vehicle seat from one construction element to the other. The force transmission element by way of at least one joint is connected to both construction elements, and conjointly with the at least one joint is an integral component part of at least one of the two construction elements.

First claim

The invention claimed is:

1. A vehicle seat comprising:
two construction elements that are movable relative to one another; and
at least one force transmission element which is configured to transmit activation forces and/or stress forces from one construction element to the other that result from the use of the vehicle seat wherein the at least one force transmission element via at least one joint is connected to the two construction elements, and conjointly, with the at least one joint, is an integral one-piece component part of at least one of the two construction elements, whereby the at least one force transmission element i) forms a monolithic multiple joint or multiple element kinematic assembly or ii) engages into a toothing that is connected to a seat lower part of the vehicle seat.

2. The vehicle seat as claimed in claim 1 , wherein the at least one force transmission element is integral to at least one of the two construction elements and movable in a material-inherently elastic manner.

3. The vehicle seat as claimed in claim 1 , wherein the at least one force transmission element comprises an all-solid joint having at least one tapered region.

4. The vehicle seat as claimed in claim 1 , wherein the at least one force transmission element is an elastically deformable leaf spring joint.

5. The vehicle seat as claimed in claim 4 , wherein a support element that is configured to absorb compression forces and is rotatably connected to at least one of the construction elements parallel with the leaf spring joint.

6. The vehicle seat as claimed in claim 1 , wherein the at least one force transmission element and the one construction element are configured as a bi-component part, wherein one fixed component is configured from rigid levers and at least one elastic component that is disposed between the rigid levers is configured as an all-solid joint.

7. The vehicle seat as claimed in claim 1 , wherein the at least one force transmission element is configured as a rigid-in-compression monolithic knuckle joint which has a partially cylindrical external fork, or a partially spherical external socket, and a partially cylindrical internal fork, or a partially spherical internal core, the external diameter of the latter bearing in a sliding manner on the internal diameter of the partially cylindrical external fork or partially spherical socket, and in that an all-solid joint is disposed between the partially cylindrical external fork, or the partially spherical socket, and the partially cylindrical internal fork, or the partially spherical core.

8. The vehicle seat as claimed in claim 1 , wherein the at least one force transmission element as a bionic joint has a joint socket that is disposed on a joint socket lever, and a ball head that is disposed on the end of a ball head lever and mounted in the joint socket, and a flexible strap that connects the ball head lever to the joint socket lever.

9. The vehicle seat as claimed in claim 1 , wherein the at least one force transmission element comprises a plurality of connection levers and of all-solid joints that are disposed between the connection levers and configure the monolithic multiple joint or the multiple element kinematic assembly between the construction elements.

10. The vehicle seat as claimed in claim 9 , wherein the monolithic multiple joint kinematic assembly comprises a monolithic quadruple joint kinematic assembly that includes a plurality of connection levers and all-solid joints that are disposed between the connection levers is connected to an activation element and to an engagement lever that locks an adjusted position of the vehicle seat.

11. The vehicle seat as claimed in claim 1 , wherein the construction elements are interconnected via elastically deformable all-solid joints and via the at least one force transmission element that is parallel with said elastically deformable all-solid joints and via all-solid joints is connected to the construction elements.

12. The vehicle seat as claimed in claim 1 , wherein when the at least one force transmission element forms a monolithic multiple joint kinematic assembly, the monolithic multiple joint kinematic assembly connects an activation element that is connected to the one construction element to a locking mechanism that is connected to the other construction element.

13. The vehicle seat as claimed in claim 12 , wherein a conventional joint for receiving abusive forces is disposed in the force flux between the activation element, the monolithic multiple joint kinematic assembly, and the other construction element.

14. The vehicle seat as claimed in claim 1 , wherein the at least one force transmission element connects an activation element that is disposed in a first plane to a construction element that is to be activated and is disposed in a second plane.

15. The vehicle seat as claimed in claim 1 , wherein the at least one force transmission element that is connected to one construction element as a monolithic gripper is linked to the connection between a first construction element that is connected to an engagement lever and a construction element to be activated.

16. The vehicle seat as claimed in claim 1 , further comprising:
a seat depth adjustment of the vehicle seat comprising:
a seat depth adjustment part which is configured to be guided in a seat lower part of the vehicle seat and is movable relative to the latter;
a locking installation for locking the seat depth adjustment part in an adjusted seat depth position of the seat depth adjustment part relative to the seat lower part the locking installation having a locking mechanism that is connected to the seat lower part and wherein the at least one force transmission element is connected to an activation element and to the seat depth adjustment part.

17. The vehicle seat as claimed in claim 16 , wherein, when the at least one force transmission element engages into the toothing, the locking mechanism is composed of the toothing and wherein a toothed lever that is connected to the at least one force transmission element engages into said toothing.

18. The vehicle seat as claimed in claim 17 , wherein the at least one force transmission element is a leaf spring joint.

19. The vehicle seat as claimed in claim 16 , comprising two seat depth adjustment parts that are guided so as to be mutually spaced apart in the seat lower part of the vehicle seat, and one locking installation having perforated toothings that are disposed on the sides of the seat depth adjustment parts and toothed levers configured to be pivoted into said perforated toothings, said toothed levers each being pivotable about conventional joints that are connected to the seat lower part and via all-solid joints being connected so as to be integral to an activation element.

20. The vehicle seat as claimed in claim 19 , further comprising two connection levers that by way of a first all-solid joint are connected so as to be integral to an activation element that is guided in the seat lower part and that by way of a second or third, respectively, all-solid joint are connected so as to be integral to in each case one toothed lever.
