ABSTRACT:
An apparatus (40, 460) for tensioning a seat belt and tightening the seat belt against an occupant. The apparatus comprises a housing (42, 462) connectable to a component of a vehicle. A flexible member (102, 482) has a first end portion (104, 484) fixed against movement relative to the housing (42, 462). A second end portion (120, 500) of the flexible member (102, 482) is connectable with a seat belt. An intermediate portion (142, 502) of the flexible member (102, 482) is located between the first and second end portions (104, 120, 484, 500). A part (144, 504) of the intermediate portion (142, 502) is located in the housing (42, 462) and defines an expansible chamber (162, 518). An actuator (202, 562), upon actuation, creates a force which acts on the part (144, 504) of the intermediate portion (144, 502) to expand the chamber (162, 518) and move the second end portion (120, 500) of the flexible member (102, 484) in a direction to tension the seat belt and tighten the seat belt against the occupant.
