ABSTRACT:
A mechanical sensor for a vehicle seat belt system comprises a casing, an inertia body mounted on the casing for movement in response to an inertial force imposed on it and an output member separate from the inertia body. A spring is coupled between the casing and the output member and biases the output member to move it relative to the casing. A release member is normally engaged between the output member and the inertial body such as to restrain the output member against movement under the bias of the spring in the absence of an inertial force on the inertia body in excess of a predetermined magnitude. Upon movement of the inertial body by an inertial force in excess of the predetermined magnitude, the inertia body releases the release member, which in turn moves out of engagement with the output member, whereupon the spring displaces the output member.
