ABSTRACT:
A belt tightener (10) for a vehicle safety belt system is connected to a seat belt buckle (16). A piston (34) located in a cylinder (32) of a driving mechanism (18) is connected to the buckle (16) by a cable (22). A gas generator (38) produces gas in response to a vehicle collision to move the piston (34) and the buckle (16) in a first direction (20) along a longitudinal axis (42) of the cylinder (32). The cylinder (32) is fixedly mounted on a support member (70) with the longitudinal axis (42) of the cylinder (32) extending along the first direction (20). The support member (70) includes a mounting portion (72) connectable to a vehicle (12). A cover (100) defines a chamber (102) in which the support member (70) and the driving mechanism (18) are located. A flexible boot (130) into which the cable (22) extends is connected to the cover (100) and extends between the buckle (16) and the cover (100).
