Abstract

The invention relates to a safety system for motor-vehicle occupants, in particular a restraint system, such as an airbag, belt tighteners, etc., which has at least one tripping sensor that exhibits a response time, one processing unit, and one final firing stage for activating the safety system. To protect against spurious tripping, an inhibiting circuit (21) is proposed, which is triggered by the processing unit (2). It cancels an interlock of the final firing stage (5) only after an interlocking enable time (t.sub.v) has elapsed, whereby the interlocking enable time (t.sub.v) is shorter than the response time (t.sub.a) of the tripping sensor (1).
