Title
(EN) WEBBING WINDING DEVICE
(FR) DISPOSITIF D'ENROULEMENT DE SANGLE
(JA) ウェビング巻取装置
Abstract
(EN)
The present invention minimizes any increase in complexity in the structure of a webbing winding device provided with a force limiter load switching mechanism and a pretensioner mechanism. The webbing winding device is provided with: a spool around which a webbing is wound; a pretensioner mechanism for winding the webbing up onto the spool by causing the spool to rotate in a windup direction when a vehicle has an emergency; and a locking mechanism for regulating rotation of the spool in a pull-out direction when the vehicle has an emergency. The webbing winding device is also provided with a force limiter mechanism for allowing the spool to rotate in the pull-out direction by a force limiter load or more when the locking mechanism regulates the rotation of the spool 2 in the pull-out direction, and a force limiter load switching mechanism for switching a force limiter load value by receiving the input of part of an actuating force for actuating the pretensioner mechanism.

La présente invention réduit à un minimum toute augmentation de la complexité de la structure d'un dispositif d'enroulement de sangle pourvu d'un mécanisme de commutation de charge de limiteur d'effort et d'un mécanisme pré-tendeur. Le dispositif d'enroulement de sangle est pourvu : d'une bobine autour de laquelle une sangle est enroulée ; d'un mécanisme pré-tendeur permettant d'enrouler la sangle sur la bobine en amenant la bobine à tourner dans une direction d'enroulement lorsqu'un véhicule est dans une situation d'urgence ; d'un mécanisme de verrouillage permettant de réguler la rotation de la bobine dans une direction d'extraction lorsque le véhicule est dans une situation d'urgence. Le dispositif d'enroulement de sangle est également pourvu d'un mécanisme limiteur d'effort pour permettre à la bobine de tourner dans la direction d'extraction par une charge de limiteur d'effort ou plus lorsque le mécanisme de verrouillage régule la rotation de la bobine (2) dans la direction d'extraction, et d'un mécanisme de commutation de charge de limiteur d'effort permettant de commuter une valeur de charge de limiteur d'effort par la réception de l'entrée d'une partie d'un effort d'actionnement pour actionner le mécanisme pré-tendeur.

 フォースリミッタ荷重切替機構及びプリテンショナ機構を備えたウェビング巻取装置の構造が複雑化することを抑制する。ウェビング巻取装置は、ウェビングが巻取られるスプールと、車両の緊急時にスプールを巻取方向へ回転させることでウェビングをスプールに巻取らせるプリテンショナ機構と、車両の緊急時にスプールの引出方向への回転を規制するロック機構と、を備えている。また、ウェビング巻取装置は、ロック機構がスプール2の引出方向への回転を規制した際に、スプールのフォースリミッタ荷重以上での引出方向への回転を許容するフォースリミッタ機構と、プリテンショナ機構を作動させる作動力の一部が入力されることでフォースリミッタ荷重値の切替えを行うフォースリミッタ荷重切替機構と、を備えている。
