ABSTRACT:
A belt clamp for use in conjunction with an emergency locking retractor in a vehicle occupant restraint belt system comprises a belt turning roll having the belt looped around it and carried by a pair of spaced-apart levers, one on either side of the frame, that are substantially rigidly joined together and mounted on the frame for rotation about an axis transverse to the frame. Springs normally hold the turning roll and levers away from a movable clamping jaw that is supported by the frame to move toward and away from a matching fixed clamping jaw. The springs yield to a substanial pull out force on the belt, thereby enabling the lever and turning roll to pivot toward and to engage and shift the movable clamping jaw toward the fixed clamping jaw, whereupon the belt is gripped between gripping surfaces on the jaws and is prevented from pulling out from the emergency locking retractor.
