Abstract
A restraint system includes a retractor housing, a webbing spool rotatably coupled to the retractor housing and defining an axis of rotation, a wire spool lockable to the webbing spool, a die fixed relative to the retractor housing, and a wire fixed to the wire spool and engaged with the die.
Claims21
A restraint system comprising:
- a retractor housing;
- a webbing spool rotatably coupled to the retractor housing and defining an axis of rotation;
- a wire spool lockable to the webbing spool;
- a die fixed relative to the retractor housing;
- and
- a wire fixed to the wire spool and engaged with the die;
- wherein the die includes an inlet and an outlet;
- the wire includes a first segment extending from the wire spool to the outlet of the die and a second segment extending from the inlet of the die;
- and
- the second segment of the wire has a cross-sectional area greater than a cross-sectional area permitted through the die.
