Seat belt retractor with reduced spooling

摘要

A seat belt retractor including a web clamp in the retractor housing to reduce the spooling effect when the retractor is locked. The webbing extends from the retractor spool about a web clamp and then outwards of the retractor housing. Extraction forces acting on the webbing in an emergency result in forcing of the web clamp against the roll of webbing to thereby prevent further withdrawal of the webbing from the spool. The web clamp is maintained in close proximity to the roll of webbing regardless of the amount of webbing left on the spool.
