Abstract
An automatic locking safety belt retractor includes a bracket supporting a belt retracting reel provided with end first ratchet wheels and a first pawl member swingable into locking engagement with the ratchet wheel and spring biased out of engagement. A second ratchet wheel is rockable relative to the reel and is connected to the first pawl to advance it with advance of the second ratchet wheel. A cam rotates with the reel shaft and a second pawl carrying inertia wheel is rotatable on the shaft, the second pawl engaging the second ratchet wheel when the inertia wheel lags the cam to thereby advance the second ratchet wheel and lock the reel. A third ratchet wheel is rotatable with the inertia wheel and an inertia sensing pendulum, when actuated, advances a locking pawl into locking engagement with the third ratchet wheel to lock the reel. The acceleration required to actuate the pendulum sensor is less than that required to lock the reel, due to the inertia lag of the inertia wheel.
