Abstract

A seat belt retractor has a frame with sidewalls and a rotatable spool extending between said sidewalls. The rotatable spool has seat belt webbing wound thereon. A locking pawl engages ratchet teeth on the outer periphery of the spool for arresting rotation of the spool. A secondary locking mechanism locks the spool against rotation.
