Abstract

It is provided adjustment system for a vehicle seat, which comprises a base, a lever, which is pivotably mounted on the base, and an adjustment unit, which is coupled to the lever and is configured to pivot the lever relative to the base. A release device coupled to the adjustment unit is provided, which release device is configured to cause a relative movement between the adjustment unit and the base on the basis of a signal indicating a vehicle collision from a collision sensor operatively connected or connectable to the release device.

Claims (23)

1 . An adjustment system for a vehicle seat, comprising

a base,

a lever, which is pivotably mounted on the base,

an adjustment unit, which is coupled to the lever and is configured to pivot the lever relative to the base, wherein the adjustment unit comprises a first component, via which the adjustment unit is coupled to the lever, and a second component, via which the adjustment unit is mounted on the base, wherein the second component comprises an axle which is displaceably guided in a slotted guide of the base, and

a release device coupled to the adjustment unit, which release device is configured to cause a relative movement between the adjustment unit and the base on the basis of a signal indicating a vehicle collision from a collision sensor operatively connected or connectable to the release device.

2 . The adjustment system according to claim 1 , wherein the first component is configured in the form of a spindle and the second component is in the form of a drive coupled to the spindle.

3 . The adjustment system according to claim 1 , wherein the second component is displaceably guided on the base.

4 . The adjustment system according to claim 1 , wherein the release unit is configured to act on the second component of the adjustment unit.

5 . The adjustment system according to claim 1 , wherein the release unit comprises an actuator which is configured to pivot a crank pivotally mounted on the base relative to the base.

6 . The adjustment system according to claim 5 , wherein the actuator is configured in the form of a motor-gear unit.

7 . The adjustment system according to claim 5 , wherein the release unit comprises a release lever which is pivotably connected to the crank.

8 . The adjustment system according to claim 1 , wherein the release unit comprises an actuator which is configured to pivot a crank pivotally mounted on the base relative to the base, wherein the release unit comprises a release lever which is pivotably connected to the crank and the release lever of the release unit is connected to the axle of the second component such that it can pivot about a pivot axis.

9 . The adjustment system according to claim 7 , wherein the release lever is movable between two end positions, wherein one arm of the crank and the release lever are each lying at a dead center in both end positions relative to each other.

10 . The adjustment according to claim 1 , further comprising a collision sensor, which is configured to detect a vehicle collision and to provide a signal indicating the vehicle collision to the release device.

11 . The adjustment system according to claim 1 , wherein the lever comprises a first arm, via which the lever is coupled to the adjustment unit, and a second arm for supporting a seat part of the vehicle seat.

12 . The adjustment system according to claim 11 , wherein the first arm and the second arm project at an angle to each other from a pivot axis of the lever.

13 . A vehicle seat having a seat part and an adjustment system according to claim 1 , wherein the seat part is supported on the base via the lever of the adjustment system.

14 . An adjustment system for a vehicle seat, comprising,

a base,

a lever, which is pivotably mounted on the base,

an adjustment unit, which is coupled to the lever and is configured to pivot the lever relative to the base, wherein the adjustment unit comprises a first component, via which the adjustment unit is coupled to the lever, and a second component, via which the adjustment unit is mounted on the base, and

a release device coupled to the adjustment unit, which release device is configured to cause a relative movement between the adjustment unit and the base on the basis of a signal indicating a vehicle collision from a collision sensor operatively connected or connectable to the release device, wherein the release unit is configured to act on the second component of the adjustment unit.

15 . A vehicle seat having a seat part and an adjustment system according to claim 14 , wherein the seat part is supported on the base via the lever of the adjustment system.
