Claims

[Scope of utility model registration request]

(1) The winding shaft on which the occupant restraint webbing is wound is biased in the webbing winding direction by the biasing force of a small elastic body, and the actuating ring is rotated in the webbing winding direction on which the biasing force of the large elastic body acts. In the webbing tensioning device that transmits the biasing force of a large elastic body to the take-up shaft by preventing the rotation during normal operation and allowing rotation in a vehicle emergency, a rotating bowl is engaged with the operating ring, and a latch member is connected to the rotating bowl. The latch member maintains the engaged state of the rotary bowl and the actuating ring by engaging with each other, and in the event of a vehicle emergency, this latch member escapes from the rotary trajectory of the rotary bowl by the driving force from the drive source, thereby engaging the rotary bowl and the actuating ring. A webbing tensioning device characterized by being able to disengage from a ring.

(2) The webbing tensioning device according to claim 1, wherein the forward latch member is a plunger that is driven in the axial direction by the excitation force of a solenoid that is a driving source.

(3) Claim 2 of the above utility model registration, characterized in that the axis of the rotating bowl is parallel to the operating ring, and the plunger is movable on an axis parallel to the axis of the operating ring. Webbing tensioning device described in.
