ABSTRACT:
A seat belt retractor includes a spindle. Seat belt webbing is wound on the spindle. The spindle is supported for rotation in belt withdrawal and belt retraction directions. A mechanism is actuatable to block rotation of the spindle in the belt withdrawal direction. A disk is supported for rotation relative to the spindle to actuate the mechanism in response to rotation of the spindle in the belt withdrawal direction relative to the disk. The disk has a plurality of teeth extending therefrom. A member is manually movable toward and away from the disk. The member has a portion for engaging one of the plurality of teeth on the disk to block rotation of the disk in the belt withdrawal direction thereby enabling rotation of said spindle in the belt withdrawal direction relative to the disk upon rotation of the spindle in the belt withdrawal direction.
