Abstract

A control system for vehicle occupant protection device in a motor vehicle has a sensor device with an X-Y acceleration sensor and a further analog sensor. The acceleration signal of the analog sensor which is rotated in its sensitivity axis by preferably 45° with respect to one of the sensitivity axes of the X-Y acceleration sensor is used here as a safing signal for checking the acceleration signals supplied by the X-Y acceleration sensor.
