摘要： In a pretensioner device, engaging teeth of a pinion (rotating body) have first projections which project-out toward the other side in the peripheral direction of a cam portion. Meshing claws of a clutch plate have second projections which project-out toward a one side in the peripheral direction of the cam portion, and whose gear portion side end surfaces face the first projections. In a state before operation of the pretensioner device, movement of the clutch plate toward one side in the axial direction with respect to the pinion is restricted due to the second projections engaging with the first projections. Accordingly, in the pretensioner device, in the state before operation, even if some type of external force is applied to the clutch plate, positional offset of the clutch plate toward the one side in the axial direction with respect to the pinion can be prevented.
摘要翻译：在预紧器装置中，小齿轮（旋转体）的啮合齿具有在凸轮部的圆周方向上朝向另一侧突出的第一突出部。离合器片的啮合爪具有朝向凸轮部的圆周方向的一侧突出的第二突起，并且其齿轮部侧端面面对第一突起。在预紧器装置操作之前的状态下，由于第二突起与第一突起接合，限制了离合器板相对于小齿轮在轴向方向上的一侧的移动。因此，在预紧器装置中，在操作前的状态下，即使对离合器片施加了某种类型的外力，也可以防止离合器板相对于小齿轮朝轴向一侧的位置偏移。

摘要： A webbing take-up device comprising: a take-up shaft that takes up a webbing belt; a metal frame that axially supports the take-up shaft; and a lock mechanism comprising a lock plate that blocks rotation in the pullout direction of the webbing of the take-up shaft by engaging the take-up shaft directly or indirectly. The lock plate is formed by performing press-punch and press-bend processing on a metal plate and has a connecting portion formed so that one end side thereof is continuous with a lock, which engages the take-up shaft. The connecting portion spans between one side and the other side of the frame.

摘要： A webbing retractor is disclosed. One end portion of a plate is fixed to a hollow cylindrical portion of a spool. An intermediate portion of the plate is entrained around an engaging pin and the like of a gear which can rotate relatively to the spool. A pawl provided at the gear abuts the plate, and is held at a position of non-engagement with stopper teeth against urging force of a coil spring. When the spool and the gear rotate relatively, the plate, whose widthwise dimension decreases toward a final end portion thereof, is taken-up onto the hollow cylindrical portion while being rubbed by the engaging pin and the like. A force limiter load in an energy absorbing process is decreased. The pawl, whose engagement with the plate is released, meshes with the stopper teeth such that rotation of the spool is impeded.

摘要： The present invention discloses a cover mounting structure for a webbing retractor. This structure relates to a mounting structure of a cover mount and a cover which hold a power spring used for taking up a webbing. By inserting a claw of the cover into an engagement hole portion of the cover mount, a claw on a folded member in which the engagement hole portion is formed enters into a hole portion of the engagement portion, so that the engagement portion is anchored by the claw. That is, the cover can easily be fixed onto the cover mount. Moreover, the engagement portion has elasticity and is constantly urged in the direction of withdrawal by the restoring force, so that the cover does not generate strange sounds.

摘要： A pretensioner for a webbing retractor is provided with a cylinder into which gas is supplied thereby moving a piston. A rack thus causes a pinion to rotate which causes a webbing to be wound onto a winding shaft. During the assembly process for the pretensioner, an O ring is fitted onto a seal holding portion of a piston and the O ring and piston are inserted together into a cylinder. Therefore, the conventional cutting process for forming a seal holding groove is unnecessary. In a normal state, the piston does not come into direct contact with the bottom portion of the cylinder, as in a conventional apparatus, instead the O ring abuts the bottom portion of the cylinder. Therefore, noise generated by the bottom of the cylinder coming into contact with the piston due to vibration and the like can be prevented.
