ABSTRACT:
A seat belt retractor comprises a main winding spring coupled between the frame and the reel shaft and an auxiliary winding spring coupled between the frame and a rotatable clutch wheel. A clutch-operating mechanism locks the clutch wheel against rotation when the belt is done up, thereby inactivating the auxiliary spring. The clutch wheel is coupled to the shaft by an elongated flexible coupling member wound spirally around a portion of the reel shaft such that it tightens when the reel shaft rotates in the belt-unwinding direction relative to the clutch wheel and loosens when the reel shaft rotates in the belt-winding direction relative to the clutch wheel.
