Abstract: An electronic sensing system for triggering the activation of a safety mechanism of a vehicle during a vehicle collision. The system includes a piezoelectric transducer providing an output indicative of shock acceleration of the vehicle, an evaluating and safety circuit for processing the output of the transducer in accordance with predetermined dynamic deformation characteristics of the vehicle and for providing a triggering output signal to an ignition circuit for activating the safety mechanism such as an air bag system. The evaluating and safety circuit provides a triggering output signal depending upon whether at least one of a predetermined threshold value has been attained by the output signal of the transducer and that the value is maintained for a predetermined delay period.
