Document Type and Number:
WIPO Patent Application WO/2019/054279
Kind Code:
A1
Abstract:
In this webbing winding device, when the pull-out acceleration of a webbing from a spool, based on the rotation angle acceleration in the pull-out direction of the spool and the winding radius of the webbing around the spool detected by a rotational angle sensor, is equal to or higher than a predetermined acceleration, a locking mechanism locks rotation of the spool in the pull-out direction. Therefore, rotation of the spool can be locked on the basis of the pull-out acceleration of the webbing from the spool.
