Claim 0:
1. A seatbelt retractor comprising:
a housing having a first end and a second end;
a spool having a first end and a second end each rotatably supported by the housing, the spool being elongated on an axis from the first end to the second end; and
a torsion bar having a first end fixed to the first end of the spool and a second end operatively engageable with the housing;
the torsion bar having a rod elongated from the first end of the torsion bar to the second end of the torsion bar, the torsion bar being designed to rotationally yield so that the first end of the torsion bar rotates relative to the second end of the torsion bar when the second end of the torsion bar is engaged with housing and rotational force applied to the torsion bar through the spool exceeds a threshold force of the rod; and
the torsion bar including a wire elongated along the axis and connected to the first end of the torsion bar and the second end of the torsion bar, the wire being designed to deform about the axis and to release from the rod during the rotation of the first end of the rod relative to the second end of the rod.
