Abstract

A configuration for triggering a restraining device has firing elements that are optically fired by an associated triggering device. In addition, an optical check signal can be transmitted to the firing element by the triggering device. An evaluation circuit evaluates light signals that have been transmitted to the triggering device. As a function of an evaluated, received light signal, a disable signal, by which emission of a firing signal is prevented, is generated by the evaluation circuit.
