ABSTRACT:
A releasing circuit for actuating a vehicular safety device includes a sensor arranged to provide an acceleration signal responsive to accelerations of the vehicle and an evaluating circuit for setting a predetermined condition for activating a release element of the safety device and responsive to the acceleration signal for effecting the activation of the release element when the predetermined condition has been satisfied by the acceleration signal. A checking circuit for the releasing circuit includes a check signal generator for producing therefrom a check signal at a predetermined level which does not satisfy the predetermined condition and for applying the check signal to a circuit between the sensor and evaluating circuit, a comparator responsive to the check signal for determining as to whether or not there is a defect or malfunction in the circuit between the second and evaluating circuit, and a second comparator responsive to an output signal of the evaluating circuit for ascertaining as to whether or not the release element has been properly activated in response to the acceleration signal under control of the evaluating circuit.
