Abstract

An inertial sensor for activating a vehicular passenger restraining system comprises a housing and a sensor body supported in the housing for a sliding translational movement under the action of inertial forces from a rest position to an activating position. A return spring bearing with one end at the sensor body and with the other end at the housing preloads the sensor body towards the rest position. A first one of a pair of electrical contacts is stationary and fixed in the housing. A second one of the pair of electrical contacts is a strip-shaped contact spring closely spaced from the stationary contact and mounted in the housing to be deflectable by the sensor body into contact with the stationary contact.
