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 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 retracts the belt webbing onto the retractor. An actuator responsive to movement of the seat during a collision actuates the drive to tighten the belt webbing against the occupant.

An assembly for use in a vehicle, said assembly comprising:
- a seat for a vehicle occupant;
- support means for supporting said seat for forward movement relative to the vehicle during a collision of the vehicle as a result of relative momentum between said seat and the vehicle;
- a belt retractor mounted on said seat and movable therewith and having a spool with belt webbing wound thereon which is extendable about the occupant for restraining movement of the occupant relative to said seat;
- means for winding said belt webbing onto said spool and for mechanically transmitting forward seat movement to wind said belt webbing onto said spool to tighten said belt webbing against the occupant during a collision of the vehicle.
