ABSTRACT:
A seat belt retracting apparatus having a spool mounted for rotation on a frame member and adapted to have a seat belt wound thereon, a pair of locking wheels having a plurality of locking teeth and fixedly mounted on the spool, a locking plate engageable with the locking teeth of the locking wheels when the seat belt is protracted and engages the body of a passenger thereby locking the seat belt against further protraction, and a retracting coil spring normally urging the spool in the retracting direction. In the apparatus, lock preventing means are provided for cooperation with the locking wheels through a driving connection between them so that the locking wheels can be temporarily prevented from the locked position and can protract over some pre-selected steps in the state in which the seat belt is engaged on the passenger's body.
