    Patent number: 5031931
    Abstract: An accelerometer for a passenger restrain system in a motor vehicle includes a housing with a path for an inertial element, and spring members for urging the inertial element toward a preselected position. When the vehicle decelerates at a rate higher than a preset rate, the ball moves away from the preselected position and closes an electrical contact. A closed chamber may be used as a dampening element for the inertial element.
