ABSTRACT:
A seat belt retractor includes a spindle having belt webbing wound thereon. The spindle is supported for rotation in belt retraction and belt withdrawal directions. The spindle is biased to rotate in the belt retraction direction. A disk member is fixed to the spindle to rotate with the spindle. A rotatable drum member is adjacent the disk member. An interconnecting member is associated with the disk member and the drum member to effect rotation of the drum member with the disk member in the belt retraction direction. A selectively actuatable lock mechanism, when actuated, limits rotation of the drum member in the belt withdrawal direction to a predetermined amount of rotation and thereafter prevents rotation of the drum member in the belt withdrawal and belt retraction directions. The interconnecting member is attached to the drum member and is engageable with a stop portion on the disk member to block rotation of the disk member and the spindle in the belt retraction direction when the second member is blocked from rotating by the lock mechanism.
