20140041166 | WEBBING TAKE-UP DEVICE - An extension rib extends from a pressing portion in the take-up direction of an ALR cam and is formed to be able to abut with an ALR pawl. Accordingly, when the ALR cam excessively rotates in the pull-out direction with respect to a set position in a maximal pulled-out state, the ALR pawl abuts the extension rib. Accordingly, it is possible to suppress a state in which the ALR pawl climbs over the pressing portion and engages with a V-gear. Namely, even if a rotation variation of the ALR cam becomes large by setting a speed reduction ratio of speed reduction mechanism to a small value, it is possible to absorb such variation by the extension rib. Thus, it is possible to absorb rotation variation of the ALR cam while improving accuracy of switching timing from the ELR(or ALR) state to the ALR(or ELR) state. | 02-13-2014 |

20160046260 | WEBBING TAKE-UP DEVICE - A webbing take-up device is obtained in which the number of rotations of a spool from the start of deformation of a first energy absorption member until the start of deformation of a second energy absorption member can exceed one rotation. In a webbing take-up device, a restricting tab is provided at an open side of the engagement recess portion. Although the leading end of the stopper pawl and the engagement recess portion face each other in the first rotation of the lock ring, a leading end of a stopper pawl is thereby unable to enter inside the engagement recess portion. The restricting tab is restricted from rotating when the leading end of the stopper pawl abuts an abutting portion of the restricting tab. When the lock ring accordingly rotates in a pull-out direction, the restricting tab moves relative to the open side of the engagement recess portion. When the leading end of the stopper pawl and the engagement recess portion face each other in this state, the leading end of the stopper pawl is thereby able to enter the engagement recess portion. | 02-18-2016 |
