Abstract

A vehicle seat for a motor vehicle, includes an adjustable seat base, an adjustable backrest surface and adjustable lateral support elements provided on the seat-side and/or the backrest-side, wherein the size or geometry of the lateral support elements, which form a pair and are opposite each other, can variously be changed, and wherein the seat base and/or the backrest surface can be tilted towards one side, electromechanical or pneumatic adjustment means being provided for this purpose.

Claims

1-7. -7. (canceled)

8. A vehicle seat for a motor vehicle, comprising:

an adjustable seat surface;

an adjustable backrest surface; and

a pair of opposing lateral support elements provided on the seat and/or the backrest, said lateral support elements being adjustable in size and geometry independent of each other; and

electromechanical or pneumatic actuating means constructed for adjusting the size or geometry of the lateral support elements and/or for tilting the seat surface and/or the backrest surface toward a side.

9. The vehicle seat of claim 8, wherein one of the lateral support elements is reducible in size and another one of the lateral support elements is enlargeable.

10. The vehicle seat of claim 9, wherein the lateral support elements are tiltable in a same direction.

11. The vehicle seat of claim 9, wherein the lateral support elements comprise a cover, which is provided with stretch folds or is retrievable from a reservoir against a restoring force or via a tracking unit.

12. The vehicle seat of claim 8, wherein the seat surface and the backrest surface are tiltable together in a same direction.

13. The vehicle seat of claim 8, further comprising surface elements arranged underneath the seat surface and the backrest surface, said surface elements being movable so as to effect a deformation of the seat surface and the backrest surface via the actuating means and so as to effect the tilting of the seat surface and/or the backrest surface.

14. The vehicle seat of claim 8, further comprising spring elements provided underneath the seat surface, said spring elements being configured so as to be adjustable regarding a hardness of the spring elements.

15. The vehicle seat of claim 14, further comprising activatable elements arranged underneath the seat surface which change a spring characteristic of the seat surface.

16. A motor vehicle, comprising at least one vehicle seat, said vehicle seat comprising

an adjustable seat surface, an adjustable backrest surface, and a pair of opposing lateral support elements provided on the seat and/or the backrest, said lateral support elements being adjustable in size and geometry independent of each other;

and

electromechanical or pneumatic actuating means constructed for adjusting the size or geometry of the lateral support elements and/or for tilting the seat surface and/or the backrest surface toward a side.

17. The motor vehicle of claim 16, comprising two said at least one vehicle seat arranged adjacent each other.
