Abstract
A retractor including emergency locking mechanism including a ratchet plate mounted on a winding shaft onto and from which a webbing is wound and unwound, an inertia member which is turned in response to the rotation of the shaft, a latch member which is turned together with the shaft in a webbing pull-out direction so as to engage a pawl with the ratchet plate to lock the shaft to prevent it from being rotated in such a direction as to allow the webbing to be pulled out of the retractor, and a locking mechanism for coupling the latch member to the shaft when the turning of the inertia member lags behind that of the shaft; and a clamping mechanism for pinching the webbing between a swingable clamping engagement member and the inner surface of the base of the retractor so as to prevent the webbing from being pulled out of the retractor, wherein a control mechanism for either swinging the clamping engagement member in a webbing pinch direction so as to put the engagement member in a first position for preventing the webbing from being pulled out of the retractor, or putting the engagement member in a second position for allowing the webbing to be pulled out of the retractor includes a control plate turnable about the same axis as the ratchet plate and supporting the pawl in a swingable member, and a lever for putting the engagement member in the first or second position in response to the turning of the control plate.
