ABSTRACT:
A pretensioner for a vehicle seat belt system comprises a fixed support member and an axially acting driving device having an output member that is movable along an axis upon operation of the driving device. The driving device is supported by the support member for movement relative to it along the axis. A trigger mechanism mounted on the driving device normally restrains the driving device by releasably coupling the output member thereof to the support member. The trigger mechanism is released in response to acceleration of an inertia mass greater than a predetermined value. The inertia mass for releasing the trigger is the driving device and the trigger mechanism, which move relative to the support member. A traction member is engaged by the output member of the driving device and transmits movement of the output member to the belt system component upon operation of the driving device.
