ABSTRACT:
An apparatus (40) pretensions seat belt webbing (16) which is extensible about an occupant of a vehicle seat (14). The apparatus (40) includes a movable first member (140), a connector (42) for connecting the first member (140) with the seat belt webbing (16), a movable second member (200), a pyrotechnic device (120) for applying a force to the second member (200) to move the second member, and force limiting coupling device (240). The force limiting coupling device (240) couples the first member (140) and the second member (200). The coupling device (240) moves the first member (140) with the second member (200) until a predetermined force is applied by the connector (42) to the first member (140) resisting movement of the first member with the second member. Thereafter, the coupling device (240) enables the second member to move relative to the first member.
