<p>A passenger restraint system including a crash sensor for deploying an air bag associated with a vehicle during a crash event. The crash sensor includes a low frequency accelerometer circuit and a high frequency pressure transducer circuit. The low frequency accelerometer circuit senses low frequency signals from the deceleration of the vehicle as a result of the crash event, and the high frequency transducer circuit senses high frequency signals from the deformation of metal components as a result of the crash event. The combination of the high frequency signals and the low frequency signals provides an accurate indication for deployment of the air bag. <IMAGE></p> |
