Summary: | To reduce a component necessary for each vehicle type and specification of a seat position.SOLUTION: A webbing winding device 10 includes: a spool 20 on which a webbing can be wound; a V-gear 38 which can rotate with rotation of the spool 20; a lock pawl 26 which restricts rotation of the spool 20 in a drawing direction by being operated; a W-pawl 44 which operates the lock pawl 26 by restricting the rotation of the V-gear 38; and a rotation angle sensor which detects a rotation angle of the spool 20. When the detected rotation angle reaches a threshold, the control device displaces the W-pawl 44 and restricts the rotation of the V-gear 38.SELECTED DRAWING: Figure 3
【課題】車種及び座席位置の仕様毎に必要な部品を低減する。【解決手段】ウェビング巻取装置10は、ウェビングが巻取り可能とされるスプール20と、スプール20の回転に伴い回転可能とされたVギヤ38と、作動されることでスプール20の引出方向への回転を規制するロックパウル26と、Vギヤ38の回転を規制することでロックパウル26を作動させるWパウル44と、スプール20の回転角を検出する回転角センサと、を備えている。そして、制御装置は検知された回転角が閾値に達した場合に、Wパウル44を変位させてVギヤ38の回転を規制させる。【選択図】図3 |
