ABSTRACT:
An accelerometer for sensing velocity changes particularly suited for passenger restraint systems in a motor vehicle for the deployment of an air bag includes a housing with contact blades and a contacting element. The contacting element is arranged to move toward the contact blades when a deceleration exceeding a threshold level is sensed. A retaining element is provided to set the blades in a preselected position so that the blades are contacted by the contacting element simultaneously thereby improving the response time of the accelerometer.
