Webbing retractor |
摘要 |
A webbing retractor which, when a webbing is drawn out instantaneously, prevents the drawing out of the webbing by operating a lock mechanism. In addition, when a vehicle is decelerated suddenly, the drawing out of the webbing is also instantaneously prevented by causing a pawl to engage with a lock wheel preventing the lock wheel from rotating. The webbing retractor includes a lever which is swung in such a manner as to be movable between a first position in which the pawl is made unengageable with the lock wheel and a second position in which the pawl is made engageable with the lock wheel. The webbing retraction also includes a lever swing member which causes the lever to be located in the first position as the take-up shaft rotates in a webbing taking-up direction and to be situated in the second position as the take-up shaft rotates in a webbing draw-out direction. Accordingly, the pawl is prevented from engaging with the lock wheel at a take-up limit of the webbing.
