20120318903 | WEBBING WINDING DEVICE - In a webbing winding device, a sub-torsion shaft is inserted from one side in the axial direction of a spool into the spool when assembling the sub-torsion shaft to the spool. Subsequently, by the sub-torsion shaft rotating in the winding direction, movement of the sub-torsion shaft with respect to the spool in the winding direction and in one side in the axial direction is inhibited. Subsequently, by a stopper being fitted from one side in the axial direction into insertion groove portions, movement of the sub-torsion shaft with respect to the spool in the pull out direction is inhibited. Accordingly, since the direction in which the sub-torsion shaft is assembled to the spool becomes only a direction parallel to the axial direction of the spool, the assembility of the sub-torsion shaft with respect to the spool may be improved. | 12-20-2012 |
20120318904 | WEBBING WINDING DEVICE - In a webbing winding device, even when a piston moves toward the other side in a movement direction due to a reaction when the piston moves to a maximum movement position, an engagement surface of a hook portion comes into contact with a subject engagement surface of a subject engagement portion, so that the movement of the piston toward the other side in the movement direction is restricted. Accordingly, the piston is prevented from returning to a standby position, and a pawl is prevented from returning to a lock position. For this reason, a state where a rotation of a locking ring in the pull-out direction is maintained. Accordingly, after the piston moves from the standby position to the maximum movement position, the piston is prevented from returning to the standby position, and the force limiter load is prevented from being changed. | 12-20-2012 |
20130126656 | WEBBING RETRACTOR - 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. | 05-23-2013 |
20130233958 | WEBBING RETRACTOR - In a webbing retractor, in a state where a second anchored portion of a sub torsion shaft is connected to a frame via a rotation impeding mechanism, when a spool is pulled by excessive tension that is applied to a webbing, there is a tendency for the spool to tilt with respect to a sleeve that is supported at the frame via the rotation impeding mechanism. In this case, a distance between a second energy absorbing portion of the sub torsion shaft and an inner peripheral surface of an insert-through hole changes. A change in the distance becomes large at an opening side of the insert-through hole, but an inner diameter of the insert-through hole is enlarged at the opening side. Due thereto, it can be made such that the second energy absorbing portion does not interfere with the inner peripheral surface of the insert-through hole. | 09-12-2013 |
20130240655 | WEBBING RETRACTOR - In a webbing retractor, a press insertion portion of a sleeve provided to a webbing take-up shaft is press-inserted into a press insertion hole of a clutch base.

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. | 10-03-2013 |
20130264408 | WEBBING TAKE-UP DEVICE - A webbing take-up device is obtained capable of suppressing generating of extraordinary noise caused by vibration accompanying vehicle travelling. A switching mechanism of a webbing take-up device is equipped with a lock ring and a body that is formed with a recessed portion that houses the lock ring. The switching mechanism is also equipped with a sheet that is attached to the body so as to cover the recessed portion housing the lock ring. Protruding portions are formed at the sheet. The protruding portions make contact with the lock ring housed in the recessed portion of the body. As a result the lock ring is restricted from vibrating inside the recessed portion. | 10-10-2013 |
20140145021 | PRETENSIONER MECHANISM - 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. | 05-29-2014 |
20140239108 | WEBBING TAKE-UP DEVICE - 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. | 08-28-2014 |
20140263798 | WEBBING TAKE-UP DEVICE - 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. | 09-18-2014 |
