Abstract
A device is provided for triggering a restraint means, e.g., a two-stage deployment airbag, the device triggering a second airbag stage as a function of a criterion, derived from the acceleration signal, and the closing velocity. The criterion is, in particular, the deployment time for the first airbag stage. As a function of the deployment time of the first airbag stage and the closing velocity, triggering classes are established which in turn define the deployment time for the second airbag stage.

1-5. (canceled)
A system for triggering a restraint system in a vehicle, comprising:
- at least one acceleration sensor for measuring an acceleration of the vehicle and generating a corresponding acceleration signal;
- a pre-crash sensor for determining a closing velocity of the vehicle in a crash;
- a control arrangement for triggering the restraint system in a crash of the vehicle, wherein the restraint system is an airbag with at least a first stage and a second stage of deployment, and wherein triggering of at least the first stage of deployment of the airbag is determined as a function of at least one criterion derived from the acceleration signal, and wherein triggering of the second stage of deployment of the airbag is determined as a function of a combination of the at least one criterion and the closing velocity.
