Claims

[Scope of utility model registration request]

A take-up shaft that winds up the occupant restraint webbing with a biasing force, a cam that receives the rotational force of the take-up shaft via a deceleration means, and a latch plate that is rotated by being pressed by the contact means when the cam rotates in the webbing winding direction. and,
a ratchet capable of engaging and separating from a latch plate;
A latch plate is provided between the latch plate and the cam, and rotates the latch plate to follow the rotation of the cam, and when the latch plate is engaged with the latch plate and rotation of the latch plate is prevented, the rotation of the cam in the webbing pulling direction is prevented. a connecting means that releases the follow-up rotation of the latch plate according to the rotation of the cam and stops the webbing when the same amount of webbing as the pulled-out amount has been taken up when the cam rotates in the webbing winding direction; and the rotational force of the winding shaft is transmitted through the friction means. a control plate provided between the control plate and the latch, a first guide means that allows the latch to engage with the latch plate by winding up the webbing a little after the webbing is attached with the door closed; and a take-up shaft. The rotational force is transmitted through the friction means to keep the latch in a state where it can be engaged with the latch plate, and then the webbing is pulled out slightly to engage them and prevent the take-up shaft from rotating in the webbing take-up direction. The middle part of the webbing is wrapped around the friction plate and a part of the webbing is held in a bent state against the webbing winding force applied to the winding shaft, and when the tension of the webbing increases, the latch is released from the latch plate. A webbing take-up device having a release means.
