A seatbelt retractor that includes a locking mechanism to prevent rotation of a spool in an extracting direction, a ratchet gearand a locking gearthat integrally rotate with the spool, a clutchthat moves a pawlfrom a rest position to an engaging position with respect to the ratchet gear, a clutch biasing member that biases the clutchin a retracting direction and in a extracting direction, and a connecting mechanism to connect the clutchto the locking gear. When extraction of the webbing is locked, a direction of biasing to rotate of the clutchis maintained in the extracting direction so that the amount of retraction of the webbing required to release the lock is reduced to achieve quick release of the lock.

Seat belt retractor

When end lock has occurred in a seat belt retractor due to winding-up of a webbing, the end lock is easily and surely released. A stop part (G) engages with a lock arm () displaced in a locking operation direction and stops the lock arm (). A lock mechanism (), in a state where the lock arm () stands still on the stop part (G), starts operation with rotation in a pull-out direction (P) of a winding drum and stops rotation of the winding drum. A transmission mechanism () transmits rotation of the winding drum to the lock arm () and displaces the lock arm () in a release direction to release the engagement with the stop part (G) is released between the time when operation of the lock mechanism () is started and the time when rotation of the winding drum is stopped. Release means () releases the engagement between the lock arm () and the stop part (G) by the transmission mechanism ().

A seat belt retractor instantly switchable between only winding of a webbing to winding and drawing-out of the webbing. Operation membermoves from a non-operation position Eto an operation position E, and locking mechanismstops rotation of a winding drum in a drawing-out direction 'P'. Movement membermoves an arrangement memberto a first position For a second position F, and arrangement memberarranges the operation member at the non-operation position Eor the operation position E. Urging meansurges the arrangement membertoward the first position F. While winding a webbing, a second maintaining portionof the movement membermaintains the arrangement memberat the second position F. Release portionof memberreleases the arrangement membertoward a first portion, where the memberis kept at the first position F
