Abstract

The invention relates to a vehicle (1), particularly a motor vehicle (1), comprising a vehicle seat (2), wherein the vehicle (1) comprises an actuator (25) for generating a load reducing movement of the vehicle seat (2) in case of a rear collision and a control means (10) for actuating the actuator (25) when a first threshold value relating to the amount of the rear collision is exceeded and a second threshold value relating to the amount of the rear collision is not exceeded.

Claims

1. Motor vehicle, the motor vehicle comprising:

a vehicle seat;

an actuator for generating a load reducing movement of the vehicle seat in case of a rear collision wherein the load reducing movement is one of a downward movement, backward movement and backward tilting rotational movement; and

a trigger module for generating a trigger signal for actuating the actuator when a first threshold value relating to the amount of the rear collision is exceeded unless a second threshold value relating to the amount of the rear collision is exceeded.

2. Vehicle according to claim 1, wherein the first threshold value is smaller than the second threshold value.

3. Vehicle according to claim 1, wherein the first threshold value is approximately 5 g ±

30%.

4. Vehicle according to claim 1, wherein the second threshold value is approximately 10 g ±

30%.

5. Vehicle according to claim 1, the motor vehicle further comprising:

a sensory mechanism for detecting a rear collision.

6. Method of operating a motor vehicle comprising a vehicle seat, the method comprising:

generating a trigger signal when a first threshold value relating to the amount of a rear collision is exceeded, unless a second threshold value relating to the amount of the rear collision is exceeded, and

by means of an actuator generating a load reducing movement of the vehicle seat if the trigger signal is present wherein the load reducing movement is one of a downward movement, backward movement and backward tilting rotational movement.

7. Method according to claim 6, wherein the first threshold value is smaller than the second threshold value.

8. Method according to claim 6, wherein the first threshold value is approximately 5 g ±

30%.

9. Method according to claim 6, wherein the second threshold value is approximately 10 g ±

30%.
