摘要： A moving member that causes a take-up shaft to rotate is prevented from passing through a limit position. In a webbing take-up device, a piston rises when a vehicle disposed with the webbing-take device experiences an emergency situation, whereby a pinion, a clutch plate, a lock gear, a torsion shaft and a spool are rotated, and a webbing is taken up. Thus, a flange of the piston abuts against a piston stopper fixed to a frame, and the rising energy of the piston is absorbed. Moreover, an upper end of the piston abuts against an inhibitor portion of a cover plate disposed at a limit position, and the rising of the piston is inhibited. Thus, the upper end of the piston causing the pinion to rotate can be reliably prevented from passing through the limit position.

摘要： In a webbing retractor having a pretensioner mechanism and a force limiter mechanism, when a drive member is rotated in one direction by the pretensioner mechanism, a cam plate is disposed at a sleeve side by an inner peripheral surface of a clutch ring. Thus, a roller engages with a sleeve, the sleeve is rotated integrally with the drive member, and a webbing is taken-up. When the sleeve is rotated in another direction by the force limiter mechanism, the cam plate is inserted into a recess portion of the clutch ring, and the cam plate is disposed at a side opposite to a sleeve side. Thus, rotation of the sleeve with respect to the drive member is permitted, and impeding of the pulling-out of the webbing can be prevented. Accordingly, a force limiter load can be determined by only a load required for deforming an energy absorbing member.

摘要： Provided is a webbing winding device capable of mounting a holding member for holding a pretensioner on a frame easily. The webbing winding device has a holder which is mounted on a leg plate only by applying loads to tip ends (upper ends) of load receiving pieces and pushing the tip end (bent portion) sides of engagement claws into hole portions. With this structure, the operation of mounting the holder on the leg plate is easy and does not need any component such as screw. As no fastening component such as screw for mounting the holder on the leg plate is required, the cost for components is reduced and as no fastening step of screw is required, such cost is also reduced.

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 is disclosed which includes a take-up shaft onto which a webbing is mound, and a mounting member nondetachably mounted to the take-up shaft by screw tightening. The take-up shaft and the mounting member are engaged with each other at a portion other than a portion where the screw tightening is carried out, thereby preventing relative rotation of the take-up shaft and the mounting member.

摘要： An amount of webbing that is pulled-out after operation of a pretensioner mechanism is reduced. In a webbing retractor 10, a lock pawl 78 is set in a non-meshable state in which it cannot mesh with a lock gear 26. At a time when a pretensioner mechanism 34 operates and a clutch plate 42 rotates in a take-up direction, a lock stopper 86 rotates together with the clutch plate 42 and releases engagement with the lock pawl 78. Therefore, the lock pawl 78 is rotated by a compression coil spring 70 and changed to a meshable state. In this way, immediately after rotational force in a pull-out direction is applied to the lock gear 26 due to load from a vehicle occupant after operation of the pretensioner mechanism 34, the lock pawl 78 meshes with the lock gear 26, and pulling-out of a webbing 20 is impeded. Therefore, an amount of the webbing 20 which is pulled-out can be reduced.

摘要： A webbing retractor which can prevent gas, which is for rotating a take-up shaft in a take-up direction, from affecting other structural parts. In the webbing retractor, when a pretensioner mechanism operates, gas for operation within a cylinder is exhausted toward a pinion via a gas venting hole formed in a flange portion of a piston. Because a blocking wall is provided between the pinion and an acceleration sensor, exhausted gas passes between the pinion and the blocking wall, and is exhausted to an outer side of the webbing retractor from an upper end side of a cover plate or the like. In this way, blowing-out of the exhausted gas onto the acceleration sensor is blocked, and the exhausted gas can be prevented from affecting the acceleration sensor.

摘要： In a webbing retractor, when a vehicle is in an emergency, a pretensioner mechanism supplies gas in a cylinder. A slider substantially closes a gas passing portion, and a piston thereby starts to move upward. A fitting portion pushes the slider upward so as to maintain the closure of the gas passing portion, and a webbing is taken up. When an energy absorbing member in a force limiter mechanism is deformed such that the webbing is pulled out, the piston is moved downward, the gas passing portion is opened by the slider so as to discharge the gas in the cylinder from the gas passing portion.

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.
