Abstract: A seat belt retracting assembly including a U-shaped support bracket rotatably supporting a reel on a shaft. A locking pawl is rotatably supported by a pin extending between the side walls of the bracket for moving to and from a locked position in engagement with a pair of spaced parallel plate-like ratchet members defining the ends of the reel. An output impeller is disposed about the shaft exteriorly of one of the side walls of the bracket and is in sealing engagement with the shaft and defines a fluid chamber. The output impeller has an arm extending therefrom with a shoulder which engages a pin extending through the adjacent side wall from the locking pawl. An input impeller is disposed about the shaft within the fluid chamber. A spiral spring is disposed about the shaft for gripping engagement with the shaft during rotation in the extending direction but which allows the shaft to freely rotate therewithin when the shaft is rotating in the retracting direction. A coil spring is disposed about the spiral spring and engages the input impeller whereby upon initial extending rotation of the reel means, the input impeller will be rotated to react through fluid in the fluid chamber with the output impeller to hold the shoulder thereof in engagement with the extension of the locking pawl to maintain the locking pawl out of the locked position. Once the initial extending rotation of the reel means has been terminated, the wound up coil spring will unwind and continue to rotate the input impeller to continue to hold the output impeller in positive engagement with the extension of the locking pawl to prevent the locking pawl from moving into locked engagement with the ratchet members until a predetermined period has elapsed after termination of the initial extending rotation of the reel means. A clutch plate, which is in frictional engagement with one of the ratchet members and includes a slot through which the extension from the locking pawl extends, is disposed between one of the ratchet members and the adjacent side wall for maintaining the locking pawl out of the locked position until there is an additional extending rotation of the reel means in response to which the clutch plate positively moves the locking pawl to the locked position.
