Webbing retractor, webbing retracting method, and vehicle

Abstract

A webbing retractor is provided that reduces the amount of webbing that is pulled-out after operation of a pretensioner mechanism. In a webbing retractor, a lock pawlis set in a non-meshable state in which it cannot mesh with a lock gear. At a time when a pretensioner mechanismoperates and a clutch platerotates in a take-up direction, a lock stopperrotates together with the clutch plateand releases engagement with the lock pawl. Therefore, the lock pawlis rotated by a compression coil springand changed to a meshable state. In this way, immediately after rotational force in a pull-out direction is applied to the lock geardue to load from a vehicle occupant after operation of the pretensioner mechanism, the lock pawlmeshes with the lock gear, and pulling-out of a webbingis impeded. Therefore, an amount of the webbingwhich is pulled-out can be reduced.
