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.

First claim

The invention claimed is:

1. A vehicle seat for a motor vehicle, comprising:
an adjustable seat surface arranged on a longitudinal axis of the vehicle;
an adjustable backrest surface;
a pair of opposing lateral support elements provided on a seat and/or a backrest, said lateral support elements being adjustable in size and geometry independent of each other;
wedge-shaped support elements provided on the seat surface and/or the backrest surface configured to tilt the seat and/or the backrest surface; and
at least one pneumatic actuator constructed for adjusting the size or geometry of the lateral support elements; and
at least one electromechanical actuator connected to the wedge-shaped support elements and constructed for tilting the seat surface and/or the backrest surface toward a side substantially perpendicular to the longitudinal axis of the vehicle.

2. The vehicle seat of claim 1 , wherein one of the lateral support elements is reducible in size and another one of the lateral support elements is enlargeable.

3. The vehicle seat of claim 2 , wherein the lateral support elements are tiltable in a same direction.

4. The vehicle seat of claim 2 , 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.

5. The vehicle seat of claim 1 , wherein the seat surface and the backrest surface are tiltable together in a same direction.

6. The vehicle seat of claim 1 , 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 actuator and so as to effect the tilting of the seat surface and/or the backrest surface.

7. The vehicle seat of claim 1 , further comprising activatable elements arranged underneath the seat surface which change a spring characteristic of the seat surface.

8. A motor vehicle, comprising at least one vehicle seat arranged on a longitudinal axis of the vehicle, said vehicle seat comprising:
an adjustable seat surface, an adjustable backrest surface, and a pair of opposing lateral support elements provided on a seat and/or a backrest, said lateral support elements being adjustable in size and geometry independent of each other;
wedge-shaped support elements provided on the seat surface and/or the backrest surface configured to tilt the seat and/or the backrest surface;
at least one pneumatic actuator constructed for adjusting the size or geometry of the lateral support elements; and
at least one electromechanical actuator connected to the wedge-shaped support elements and constructed for tilting the seat surface and/or the backrest surface toward a side substantially perpendicular to the longitudinal axis of the vehicle.

9. The motor vehicle of claim 8 , comprising two said at least one vehicle seat arranged adjacent each other.
