Abstract

In a method for restraining vehicle occupants in which the loads on the vehicle occupants are reduced during the restraining process, a method for restraining vehicle occupants by dissipating kinetic energy provides that firstly a possible accident is sensed and then a force which acts in the direction of the impact is applied to the vehicle occupant at the latest at the time of the first contact between the vehicle and the obstacle, the force being set over the entire braking distance so that a constant acceleration acts on the vehicle occupant so that the dissipation of the kinetic energy occurs uniformly.

Claims

1. A method for restraining occupants of a vehicle in the event of an impact against an obstacle by dissipating kinetic energy of the vehicle occupant, comprising the steps of:

sensing a possible accident;

applying a force that acts in a direction of the impact to the vehicle occupant at the latest at a time of a first contact between the vehicle and the obstacle; and

setting the force over an entire braking distance so that a constant acceleration acts on the vehicle occupant to dissipate kinetic energy uniformly.

2. The method according to claim 1, further comprising the step of moving the vehicle occupant is in the direction of the impact in accordance with the force applying step.

3. The method according to claim 1, wherein the force applied in the applying step acts on the vehicle occupant over an area.

4. The method according to claim 1, wherein the force is applied to the vehicle occupant in the force applying step by a plurality of restraining systems that are actuated one of in succession and simultaneously.

5. The method according to claim 1, wherein the force is applied in the force applying step by different restraining systems in accordance with the direction of the impact.
