Abstract

A vehicle occupant safety system, in particular a restraining system such as an airbag, safety-belt tightener or the like, includes a sensor device having at least two sensors, a preprocessing device comprising at least two preprocessing circuits, for the sensor signals, a computing system and a trigger circuit including at least two stages, for a safety device. For providing a high degree of safety with relatively low costs, the computing system is constructed as a single-computer system in such a way that it processes the data of two preprocessing circuits in two programs with staggered timing with respect to one another.
