Abstract
A belt clamping mechanism for a seat belt retractor having a belt reel rotatably journaled on a frame and a locking means for locking the reel against unwinding rotation. The retractor frame is mounted on the vehicle body for limited movement in the direction of belt pull. A yieldable device such as a frangible member acts between the frame and the vehicle body to establish the frame at a normal position in which a belt clamping member carried by the retractor frame is spaced from a clamping abutment mounted on the vehicle body. When the reel is locked and an occupant restraint load is imposed on the belt, the yieldable device permits movement of the reel and the frame in the direction of belt pull so that the belt is clamped between the clamping member carried by the frame and the clamping abutment mounted on the vehicle body to fix the belt length against spooling down on the reel.
