Abstract

A retractor includes a pretensioner whereby increased control and variation over the load limitation characteristics of the retractor are provided. The seat belt and spool are linked to a locking mechanism through a first force limiting element, while the pretensioner is linked to the seat belt and spool through a second force limiting element. A selectively actuatable clutch is provided to operatively link the pretensioner to the spool via the second force limiting element.
