Abstract
An acceleration responsive automatic braking safety belt retractor includes a mounting bracket having opposing side plates between which is journalled a shaft carrying a belt retraction wheel between the side plates and a ratchet wheel along the outside face of a first plate. A guide plate is affixed to the first plate outside face and has a circular opening registering with the ratchet wheel periphery and a linear guide slot vertically tangent to the opening and terminating at its top in a transverse stop shoulder and communicates along its upper inner side with the opening, the lower part of the communication being delineated by an outwardly downwardly inclined second stop shoulder. A stop member is longitudinally slidably engaged and depends from the slot and is provided with an inwardly directed projection having an arcuate upper edge and a bottom edge parallel to the second shoulder. A lever engages the stop member bottom edge and is swung upwardly by an acceleration actuated pendulum to raise the stop member and bring the projection into engagement with the ratchet wheel to brake it and the reel. In a modification, a second opposing slot and stop member are provided and the stop members being lever intercoupled to operate simultaneously.
