ABSTRACT:
A pair of pawls engageable with a ratchet wheel by the actuation of an acceleration detector are adapted to oscillate a lock bar through a working plate, so that said lock bar can prevent the rotation of a take-up shaft solidly secured to said ratchet wheel, to thereby stop the wind-out of a webbing for restraining an occupant which has been wound up by said take-up shaft. Particularly, since said pair of pawls are mounted on said acceleration detector through a balancer, either one of the pawls can reliably engage the ratchet wheel. Furthermore, since those pawls are guided by a guide member or members, the balancer and pawls are improved in stability.
