Claims

[Claims for Utility Model Registration] A take-up shaft for winding occupant restraint webbing in layers, and a winding shaft arranged to be rotatable relative to the winding shaft, and a rotation lag relative to the winding shaft due to sudden withdrawal of the webbing. A webbing take-up device comprising a lock wheel in which the webbing occurs, and a take-up shaft rotation stop means for stopping the rotation of the take-up shaft due to a rotation delay of the lock wheel, the webbing retractor comprising: a lock wheel that causes a rotation delay of the lock wheel; an engaging means that disables the rotational delay of the locking wheel by engaging the shaft with the webbing shaft; A webbing retractor comprising: a mass body for actuating the engaging means.
