Claims

[Scope of utility model registration request]

(1) A take-up shaft that winds up the occupant restraint webbing, a frame that pivotally supports the take-up shaft, an internally toothed ratchet foil fixed to the outside of this frame, and a pawl that corresponds to this internally toothed ratchet. a lock plate provided, a guide means for attaching the lock plate to the winding shaft, rotating it together with the winding shaft, and guiding the lock plate so as to be movable in only one direction within a plane perpendicular to the axis of the winding shaft; a rotating wheel that is coaxially supported with the winding shaft and causes a rotation delay with respect to the winding shaft in the event of a vehicle emergency;
A webbing take-up device comprising: a cam means provided between the rotary ring and the lock plate for moving the lock plate to engage the internally toothed ratchet wheel when the rotation of the rotary ring is delayed.

(2) The guide means includes a guide protrusion formed in an elongated shape when viewed in the axial direction toward the winding shaft, and a lock plate formed on the lock plate so that when this guide protrusion is inserted, the lock plate only moves in the longitudinal direction of the guide protrusion. 2. The webbing retractor according to claim 1, further comprising: an elongated guide hole that allows movement of the webbing retractor.

(3) The rotating wheel is characterized in that when the take-up shaft rapidly rotates in the webbing unwinding direction, a rotation delay occurs with respect to the take-up shaft due to inertia force.
The webbing take-up device according to item 1 or 2.

(4) The rotation of the rotating wheel is stopped by the operation of an acceleration sensor in the event of a vehicle emergency, resulting in a rotation delay with respect to the winding shaft. The webbing take-up device according to any one of the above.
