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.
Claims33
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.
