Abstract
A vehicle seat belt retractor (10) includes a spool (170) on which seat belt webbing (16) is wound. The spool (170) is supported for rotation on hubs (102, 162). In the event a primary belt locking mechanism (270) fails to block withdrawal of belt webbing (16) from the retractor (10) in a vehicle emergency situation, the spool (170) moves into engagement with a series of fixed teeth (60, 70) on the retractor frame (40) to block rotation of the spool in the belt withdrawal direction (192). Barbs (130, 168) on the hubs (102, 162) cooperate with blocking members (120, 166) to maintain the spool (170) in its blocked condition after termination of the emergency situation.
