Abstract
A seat belt retractor (20) comprising: a spool (25) and a frame (52) for rotationally supporting the spool; a seat belt (16) receivable on the spool, a rewind spring (80) for biasing the spool in a belt winding direction comprising a spring (80) having an inner spring end (82) connected to and rotated by a shaft (56) movable with the spool and a fixedly secured outer spring end (84); an auxiliary spring (120) and gear set (100, 102) (70, 72, 80, 81) operatively connected to the inner spring end in continuous driving connection with the shaft for generating a torque to reduce the level of force imparted to the shoulder of a seat belt user and to increase the rewind force when the rewind spring is rewinding the seat belt.
