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 magnetically biased contacting element. The contacting element is arranged to move toward the contact blades when a deceleration exceeding a threshold level is sensed. A cylindrical permanent magnet is used to bias the contacting element. The magnet is contained in an insert, and a seal is disposed between the insert and the housing.
