Abstract
The invention is directed to a circuit arrangement for the recording of false release signals for a restraint system such as an air bag system or a seat belt tensioning system in a vehicle. In this circuit arrangement, a release circuit including a first deceleration sensor and an evaluation circuit generates a release signal in the event of a deceleration caused by an accident. This release signal, however, becomes effective only if, at the same time, a second release circuit including a second deceleration sensor 17 responds, thereby triggering the restraint system. A monitoring circuit for monitoring the occurrence of a release signal without a concurrent response of the second release circuit will activate a warning device and inform the operator of the vehicle of the malfunction.
