Abstract
A seat belt retractor for a vehicle includes a spindle on which belt webbing is wound. The spindle is supported for rotation in belt retraction and belt withdrawal directions. Rotation of the spindle causes rotation of a first ratchet wheel from which a plurality of teeth extend. A lever is movable into engagement with a tooth on the first ratchet wheel to block rotation of the first ratchet wheel in the belt withdrawal direction. The spindle is also connected to a second ratchet wheel from which a plurality of teeth extend. A resiliently deflectable member is engageable with one of the plurality of teeth on the second ratchet wheel to block rotation of the spindle in the belt retraction direction. The resiliently deflectable member deflects to permit the lever to disengage from the first ratchet wheel and prevent a double lock condition in which the spindle cannot rotate in either the belt withdrawal direction or belt retraction direction.
