ABSTRACT:
An energy absorbing seat belt retractor comprising: a frame (22); a spool (24) rotatably mounted relative to the spool including a lock wheel (212) having a plurality of lock teeth (214) associated therewith and adapted to receive a seat belt thereabout; a lock pawl (224) for engaging the spool upon sensing a one of a vehicle deceleration and seat belt extraction above certain determinable levels; and movable nut (90)located in the spool and for prohibiting relative movement between the lock wheel and spool below a threshold input force level generated in part by occupant load on the seat belt and for generating in cooperation with a deformable bushing (100) having known deformation characteristics, the characteristics of which are controlled by a movable sleeve (242) moved about the bushing, to generate a controlled energy dissipating reaction force on the seat belt.
