Abstract
A seat belt retractor has a spool mounted for rotation in the retractor, for retraction or pay-out of seat belt webbing depending upon the rotation direction of the spool. A locking ring is attached to one end of the spool. A locking pawl locks the locking ring against rotation when a crash is sensed. Load limiting is provided by a length of wire and a winding drum attached to one of the spool and the locking ring and a pin fixed to the other of the spool and the locking ring. The wire is coiled around the pin and arranged so that when there is relative movement between the spool and the locking ring, then the wire is pulled around the pin and is wound onto the winding drum.
