Abstract: The present disclosure presents a webbing take-up device, which comprises: a spool; a lock section that is restricted from rotating at a time of a vehicle emergency so as to limit rotation of the spool in the pull-out direction; a force limiter mechanism that permits rotation of the spool in the pull-out direction at a force limiter load or greater when rotation of the spool in the pull-out direction with respect to the lock section is being limited; a switching member that switches a load value of the force limiter load by switching between a rotation-restricted state and a rotation-enabled state; and a mounting member that includes a switching member mounting section at which the switching member is disposed, and a restriction section that is engaged with the switching member so as to restrict displacement of the switching member disposed at the switching member mounting section.

Abstract: A webbing retractor is provided that can improve balance of load that a torsion shaft receives from a spool. Fit-together projections are formed at a spool side engaging portion of a main torsion member. Further, a load receiving portion is formed at a webbing insert-through hole side at the spool side engaging portion. Rotation radius direction components of rotational forces, that respective inclined surfaces of the fit-together projections receive from respective inclined surfaces of rotation restricting holes, are nullified by a rotation radius direction component of rotational force that the load receiving portion receives from a load imparting portion. Due thereto, balance of load that the main torsion member receives from a spool can be improved.

Abstract: A restriction rotating body is provided at a carrier plate, on the opposite side of a sun gear to a planet gear. When an internal-toothed gear is displaced together with a sensor gear in the rotation radial direction thereof, the internal-toothed gear presses a shaft portion of the restriction rotating body, and further, a gear portion of the restriction rotating body presses the sun gear. Due thereto, the amount of relative displacement of the internal-toothed gear with respect to the sun gear can accordingly be reduced. Moreover, since the restriction rotating body does not mesh with the internal-toothed gear, the restriction rotating body can be easily assembled after assembly of the planet gear. The planet gear can accordingly be easily assembled prior to assembly of the restriction rotating body.

Abstract translation: 限位旋转体设置在承载板上，在太阳齿轮对行星齿轮的相对侧。 当内齿齿轮与传感器齿轮一起沿其旋转径向位移时，内齿轮按压限制旋转体的轴部，并且限制旋转体的齿轮部按压太阳齿轮 。 由此，可以减少内齿轮相对于太阳齿轮的相对位移量。 此外，由于限制旋转体不与内齿轮啮合，因此在行星齿轮组装之后可以容易地组装限位旋转体。 因此，行星齿轮可以在组装限制旋转体之前容易地组装。

Abstract: A webbing take-up device is obtained in which the number of rotations of a spool from the start of deformation of a first energy absorption member until the start of deformation of a second energy absorption member can exceed one rotation. In a webbing take-up device, a restricting tab is provided at an open side of the engagement recess portion. Although the leading end of the stopper pawl and the engagement recess portion face each other in the first rotation of the lock ring, a leading end of a stopper pawl is thereby unable to enter inside the engagement recess portion. The restricting tab is restricted from rotating when the leading end of the stopper pawl abuts an abutting portion of the restricting tab. When the lock ring accordingly rotates in a pull-out direction, the restricting tab moves relative to the open side of the engagement recess portion. When the leading end of the stopper pawl and the engagement recess portion face each other in this state, the leading end of the stopper pawl is thereby able to enter the engagement recess portion.

Abstract: In a webbing take-up device, a structure for interlocking a second lock pawl with a first lock pawl is only a shaft. It also suffices for switching between restricting of rotation of a lock ring and cancelling of the restricting to be carried out merely by moving a piston by gas pressure generated at a gas generator. In this way, by a simple structure, it is possible to switch between a mode, in which torsional deformation is brought about at a sub torsion main body of a sub torsion shaft, and a mode, in which torsional deformation is not brought about at the sub torsion main body of the sub torsion shaft.

Abstract: A webbing pull-in device has a take-up shaft at which a webbing can be pulled in due to the take-up shaft being operated, a first pulley that is rotated at a time of an emergency of a vehicle, and a second pulley that, by being rotated, operates the take-up shaft. Further, the webbing pull-in device has a connecting wire that connects the first pulley and the second pulley, and that, by being taken up onto the first pulley at a time when the first pulley is rotated, transmits rotational force of the first pulley to the second pulley.

Abstract: In a webbing take-up device, configuration is made such that in a state in which a restriction wall of a cam gear is positioned at a lateral the side of a pin of a link configuring a switching section, the restriction wall abuts the pin when the link attempts to move. The restriction wall does not actively move the link regardless of the number of revolutions made by the cam gear. Operation noise of the link, a stopper pawl and a slide stopper accordingly does not occur during pull-out and take-up of webbing during normal usage, and a desirable user sensation is achieved in pull-out and take-up of the webbing during normal usage.

Abstract: In a pretensioner mechanism, movement of a piston is anchored by an anchoring pin. The anchoring pin is crushed and the piston is allowed to move. Hence, a pinion is turned by a rack of the piston. A facilitating cavity is formed in the anchoring pin. Crushing and deformation of the anchoring pin in a diametric direction thereof due to a movement of the rack is facilitated by the facilitating cavity. Therefore, the anchoring pin may be easily crushed and deformed in the diametric direction by the movement of the rack, and the action of the anchoring pin caused by the movement of the rack may be effectively made consistent.
