Abstract
A vehicle seat belt retractor comprises a tension-reduction mechanism in which a second spiral winding spring is connected in parallel with the main spiral winding spring between the retractor frame and the belt reel. A gear clutch is interposed between the second winding spring and the reel. One element of the gear clutch is selectively locked to the reel frame in response to connection of the belt to the buckle, thereby preventing the second spring from acting on the reel. When the belt is disconnected from the buckle, both springs work in parallel to wind the belt onto the reel.
