Abstract

A motor vehicle seat includes at least a seat area, a backrest and, if necessary, a headrest as seat elements. The motor vehicle seat includes at least one detachable bolting unit assigned to the seat area and/or the backrest. Furthermore, at least one handle is provided to act on the bolting unit(s). The seat elements can assume several different functional positions. The single handle is arranged to act on at least an electrical drive assigned to the bolting unit(s) and thus to execute all functional positions.

First claim

The invention claimed is:

1. A motor vehicle seat comprising:
a plurality of seat elements comprising at least a seat area and a backrest;
a first unlockable bolting unit corresponding to the seat area and a second bolting unit corresponding to the backrest;
a single handle for acting on the bolting units, whereby the seat elements can assume different functional positions; and
at least two electrical drives that correspond to the first and second bolting units, wherein the single handle is configured to act on the two electrical drives to execute all functional positions.

2. The motor vehicle seat of claim 1 , wherein the two electrical drives include a bolting drive and a folding drive.

3. The motor vehicle seat of claim 2 , wherein the bolting drive is configured to act on the bolting unit corresponding to the seat area.

4. The motor vehicle seat of claim 2 , wherein the folding drive is configured to act on the bolting unit corresponding to the backrest.

5. The motor vehicle seat of claim 4 further comprising a headrest, wherein the folding drive additionally acts on the bolting unit corresponding to the headrest.

6. The motor vehicle seat of 2 further comprising a connector arranged between each of the electrical drives and the corresponding bolting unit.

7. The motor vehicle seat of claim 6 , wherein the connector is formed as a flexible connector.

8. The motor vehicle seat of claim 2 , wherein the handle, during activation, triggers a first sensor to act on the bolting drive.

9. The motor vehicle seat of claim 8 further comprising a second sensor to act on the folding drive.

10. The motor vehicle seat of claim 9 further comprising a third sensor which records an attainment of an end position.

11. The motor vehicle seat of claim 3 , wherein the folding drive is configured to act on the bolting unit corresponding to the backrest.

12. The motor vehicle seat of claim 7 , wherein the flexible connector is a Bowden cable.

13. The motor vehicle seat of claim 1 , wherein the seat elements are movable between a normal position and a folded position.

14. The motor vehicle seat of claim 13 , wherein the seat elements are movable to an intermediate position that is between the normal position and the folded position.

15. The motor vehicle seat of claim 1 , wherein the motor vehicle seat is a rear seat.
