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 und 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; and

a control means 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:

by means of the vehicle seat performing a load reducing movement 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.

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

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

30%.

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

30%.
