Abstract
Two different switching signals for switching through the safety switching element (22) for the second firing stage of an occupant protection component which can be triggered in multiple stages are formed in the control device (3). The two switching signals are emitted to different outputs (14, 16) of the control device (3) and then subjected to an AND operation.
