  • Patent number: 12240412
    Abstract: A webbing winding device includes a spool, a sensor lever, a solenoid, and a controller. In a state where the sensor lever is disposed at the first position, the rotation in the drawing-out direction of the spool is enabled, and in a state where the sensor lever is disposed at the second position, the rotation in the drawing-out direction of the spool is locked. When the solenoid is actuated, a part of the sensor lever is attracted and the sensor lever is displaced from the first position to the second position. The controller adjusts the attracting force by which the solenoid attracts a part of the sensor lever. The controller adjusts the attracting force after completion of displacement to the second position of the sensor lever to an attracting force weaker than the attracting force F at the time of completion of displacement to the second position.

  • Patent number: 12221170
    Abstract: In a deflector device, when an external force acts on an deflector body while at a deployed position such that the deflector body is rotated in a stowing direction, even if further rotation of the deflector body in the stowing direction is restricted, the deflector body is rotated to the deployed position by an urging force of a torsion coil spring when the external force acting on the deflector body is released. This enables the deflector body to be rotated to the deployed position from anywhere over an entire rotatable range in the stowing direction by the urging force of the torsion coil spring. Thus, the torsion coil spring is able to rotate the deflector body to the deployed position in a suitable manner.
