Abstract
The specification describes a webbing-locking mechanism suitable for use in vehicle seat belt. The mechanism includes a guide roller, a ratchet gear rotatable integrally with the guide roller, a ratchet lever capable of assuming either engagement position where the ratchet lever is in complete engagement with the ratchet gear or non-engagement position where the ratchet gear is allowed to undergo free rotation, and a pawl capable of assuming either a first position where the pawl is in engagement with the guide roller or a second position where the pawl is out of engagement with the guide roller. When a tensile force of a predetermined value or greater is applied to the webbing, the ratchet lever is brought into engagement with the ratchet gear. When the guide roller has been turned further and the ratchet lever has been moved to the engagement position, the pawl is caused to move to the first position. The above structure is effective to shorten the time required until the guide roller has been fully stopped, in other words, to minimize the length of the webbing which may be pulled out of a retractor in the event of emergency.
