ABSTRACT:
A pretensioner for a vehicle seat belt system comprises a casing, a drive mechanism including a spring having an operating end and an output member coupled to the operating end, a trigger mechanism for restraining the drive mechanism in a preloaded state and including a toggle linkage engaged between the casing and the drive mechanism, and a sensor mechanism having a output member for releasing the trigger mechanism upon acceleration in excess of a predetermined value by causing articulation of the toggle linkage about a pivot axis such that it ceases to be engaged between the drive mechanism and the casing and thereby releases the drive mechanism from the preloaded state.
