INERTIA REEL USING MODULAR LOCKING MECHANISM

摘要

INERTIA REEL USING MODULAR LOCKING MECHANISM An emergency locking safety belt retractor having a modular locking pawl actuator subassembly for transferring the rotational movement of a webbing storage reel of the retractor to a locking pawl to move the locking pawl from a deactivated to an activated position in engagement with a locking ratchet to prevent further webbing protractive rotation of the reel. The actuator subassembly includes a shiftable housing containing a vehicle inertia sensor which activates a program pawl to engage a program ratchet wihch transfers the rotation of the storage reel to the subassembly housing and in turn to the locking pawl to lock the reel in response to an emergency condition.
