ABSTRACT:
Seat belt retractors for spooling seat belts (webbings) include multiple independent torque transmission or absorbing systems. The seatbelt retractor comprises a webbing, a spool, a pinion, a pretensioner, at least one coupler pawl, and a locking mechanism including a lock base and a lock pawl. The at least one coupler pawl is positioned in a cavity in the spool. During a predetermined low acceleration event, the at least one coupler pawl pivots so that a portion of the at least one coupler pawl leaves the cavity and engages the lock base to load the lock base which is then prevented from rotating in a spool extracting direction by the locking pawl. When the pretensioner activates during a predetermined higher acceleration event, the pretensioner rotates the pinion in the webbing retraction direction to rotate the spool in the webbing retraction direction.
