ABSTRACT:
A seatbelt retractor is disclosed having a frame, a spindle, a tread head and a torsion bar. The frame is attached to a structure of a vehicle. The spindle is rotatably supported by the frame. The tread head is matingly coupled to the spindle for relative rotational movement therewith and the tread head is rotationally fixable relative to the frame. The torsion bar has a torsion bar first end fixed to a first spindle end and a torsion bar second end fixed to the tread head and the torsion bar has a protrusion that selectively engages the spindle after the tread head has been fixed and the spindle has rotated a predefined angle α relative to the fixed tread head.
