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.

An accelerometer for sensing velocity changes of a motor vehicle, said accelerometer comprising: a housing having a side wall, a first end and a second end; tubular path means for defining a path extending between said first and second ends substantially coextensively with the length of the housing; a first blade disposed at a first preselected distance from said first end and extending into said path; a second blade disposed at a second preselected distance from said first end smaller than said first blade and extending into said path; and an inertial mass disposed in and guided by said tubular path, said inertial mass being biased toward said first end by a biasing force generated by said first blade; said inertial mass being adapted to move in said tubular path in response to an acceleration toward said first end bending said first blade to contact said second blade.
