Abstract

A seat belt retractor has a spool that is rotatable about an axis for receiving seat belt webbing. A locking means prevents rotation of the spool during a crash to prevent webbing payout. A load limiting means has a torsion bar extending through the spool and connected in a force path between the locking means and the webbing. One end of the torsion bar is attached to the spool, and the opposite end of the torsion bar is attached to a toothed wheel, wherein said opposite end of the torsion bar is connected to the toothed wheel in an axially adjustable manner.
