Abstract
A seat belt retractor lock up mechanism comprises a main ratchet gear (20) mounted on one end of a spool carrying seat belt webbing (100) in helical wrap. The main ratchet gear (20) is engageable by a lock dog tab (80) located on supporting slots (120, 125) formed in opposite upstanding walls (10, 11) of the retractor housing. A vehicle inertial response pendulum (40) is coupled to the lock dog tab (80) through a pilot pawl (50) and gear (15) assembly mounted on the end of the spool opposite the main gear (20). Upon collision, the pendulum (40) pivots the pilot pawl (50) into the pilot gear (15). During pay out of the belt webbing (100), the pilot gear (15) thrusts the pilot pawl (50) into the lock dog tab (80), pivoting the tab (80) into the main ratchet gear (20) for lock up. The main ratchet gear (20) and lock dog tab (80) receive most of the load during collision, enabling the pilot pawl (30) and pendulum (40) to be small and light weight.
