Abstract

A vehicle crash sensor which operates to activate a passenger safety device such as an airbag inflator is calibratable to provide a desired sensitivity of the sensor to decelerating crash pulses of varying magnitude and duration. The sensor includes an adjustable member which varies the volume of a controlled quantity of damping fluid simultaneously with variations of the piston travel distance.
