AUTOMATIC LOCKING SAFETY BELT RETRACTOR ABSTRACT OF THE DISCLOSURE An automatic braking safety belt retractor includes a shaft journalled to a bracket and spring biased in a belt retraction rotating direction. Affixed to the shaft is a take-up reel, and first and second ratchet wheels with the same number of teeth. A first spring retracted pawl is movable into engagement with the first ratchet wheel and a tooth carrying actuating member is slidable along a path tangent to the second ratchet wheel between a retracted first position with the tooth disengaged from the second ratchet wheel, a second position with the tooth engaging the second ratchet wheel, and a ratchet wheel advanced third position. A bracket mounted acceleration sensing pendulum upon actuation shifts the actuating member to its ratchet wheel engaging second position, the belt extraction rotation of the second ratchet wheel advances the actuating member which is coupled to the first pawl to advance the first pawl into engagement with the first ratchet wheel. The ratchet wheels are so angularly related and the actuating member and first pawl member are so related that the first pawl always advances into engagement with the first ratchet wheel deeply between successive teeth.
