The invention describes a process for triggering a passive safety device for vehicle occupants inside a vehicle, in particular airbags, pretensioning systems, buckle switches, and roll-over bars, where-by means of electric sensors, an evaluation circuit evaluating the acceleration signals of these sensors, and a triggering agent-an activation of these triggering agents is effected if the acceleration signals indicate a vehicle condition which may be potentially hazardaous for the vehicle occupants. According to the invention, the sensor signals will first be quantified, followed by detection of those signals that indicate simultaneously an impact direction against the direction of vehicle travel. At the same time that such sensor signals are detected, a linearly increasing crash signal as well as a trigger threshold increasing with the clock pulse are generated. If the crash signal reaches this dynamic trigger threshold, the trigger agents will be activated. The process according to the invention will cause an excellent time behavior, that is, it will lead to a very fast ignition of the safety devices in the event of a vehicle crash hazardous to vehicle occupants.
