Abstract
Abstract An assembly for use in a vehicle includes a seat for a vehicle occupant. The seat is supported for forward movement relative to the vehicle during a collision. A seat belt retractor is mounted on the seat. Belt webbing (82) extends from the retractor and about the occupant to restrain movement of the occupant relative to the seat. The belt webbing is retractable onto the retractor to tighten the belt webbing about the occupant. A drive (132) retracts the belt webbing onto the retractor. An actuator (142) responsive to movement of the seat during a collision actuates the drive to tighten the belt webbing against the occupant.
