Abstract:
A configuration for triggering a restraining device in a motor vehicle, comprising:a light source emitting an optical firing signal; a triggering device having a control circuit connected to and controlling said light source and initiating an optical check signal to be emitted by said light source; a firing element associated with a restraining device; an optical transmitter optically coupled to said firing element and to said light source for transmitting said optical firing signal emitted by said light source to said firing element; a light sensor optically coupled to said optical transmitter and receiving a light signal transmitted in answer to said optical check signal; said triggering device having an evaluation circuit connected to said light sensor for evaluating said light signal received by said light sensor, said evaluation circuit generating a disable signal in dependence on an evaluation of said light signal for preventing an emission of said optical firing signal.
