摘要： A webbing take-up device and a vehicle are provided in which different force limiter loads can be selected at arbitrary times with a simple structure. A wire is inserted into a spool. One end portion of the wire is fixed to a lock base. Thus, when rotation of the lock base is impeded, a twisting load of a torsion bar and a drawing-through load of the wire are applied to a webbing as force limiter load. Further, a cutting gear is disposed between the spool and the lock base. When the cutting gear is rotated at an arbitrary time, the wire is cut. In this way, the force limiter load is reduced to only the twisting load of the torsion bar. As a result, different force limiter loads can be selected at arbitrary times with a simple structure.

摘要： A guide pin is provided erect at a lock plate of a webbing retractor. A guide hole is formed in a V gear in correspondence with the guide pin. The guide hole is formed from a first hole portion, a second hole portion and a third hold portion. A state in which the guide pin is positioned in the first hole portion is an initial state. When relative rotation between the V gear and a spool arises, the guide pin moves from the first hole portion and reaches the second hole portion. In this process, the guide pin pushes the V gear so as to rotate reversely, and locking is cancelled. When a pushing force causing a V gear reverse rotation angle to exceed a set value is applied from the guide pin, the guide pin escapes into the third hole portion such that excessive pushing force is cancelled.

摘要： A webbing retractor includes a take-up shaft, an inertia plate provided integrally and coaxially with the take-up shaft, and an inertial force imparting mechanism. When a webbing for restraining a vehicle occupant is suddenly pulled-out, the take-up shaft takes-up the webbing, and the inertia plate causes a rotational delay with respect to the take-up shaft, and rotation of the take-up shaft in a webbing pull-out direction is thereby locked. Further, the inertial force imparting mechanism that suppresses and deters rotation of the inertia plate in a webbing take-up rotation direction by the inertial force imparting mechanism applying inertial force in a webbing pull-out rotation direction to the inertia plate which attempts to rotate in a webbing take-up direction even after rotation of the take-up shaft in the webbing take-up rotation direction has stopped when a vehicle occupant cancels an applied state of the webbing and the entire webbing is taken-up.

摘要： An inexpensive webbing retractor is obtained by making a pretensioner and a lock device small and reducing the number of parts. A plurality of protrusions are formed on an inner peripheral portion of the bearing body, which pivotally supports a clutch portion. These protrusions are brought into linear contact with an outer peripheral portion of the clutch portion, whereby the bearing body pivotally supports the clutch portion indirectly via the protrusions. Since the protrusions are brought into linear contact with the clutch portion, the contact area becomes quite small. Hence, the protrusions are easily plastically deformed due to friction resistance with the clutch portion. Therefore, resistance that obstructs the rotation of the clutch portion becomes small, and gas pressure can be efficiently supplied for the rotation of a take-up shaft. Also disclosed is a locking device comprising a lock base attached to the winding spool, a lock plate for engagement with ratchet teeth of a frame, and a lock cover which comprises a hook portion with which the lock base is engaged, and an outer peripheral flange portion overlapping the frame.
摘要翻译：通过使预紧器和锁定装置小型化并减少零件数量，可以获得廉价的卷绕卷收器。在轴承体的内周部形成有多个突起，该突起枢转地支撑离合器部。这些突起与离合器部分的外周部分线性接触，由此轴承体经由突起间接地枢转地支撑离合器部分。由于突起与离合器部分线性接触，所以接触面积变得非常小。因此，由于与离合器部分的摩擦阻力，突起容易塑性变形。因此，妨碍离合器部的旋转的阻力变小，能够有效地供给气体压力来进行卷取轴的旋转。还公开了一种锁定装置，其包括附接到卷轴的锁定基座，用于与框架的棘轮齿接合的锁定板，以及锁定盖，其包括锁定基部与其接合的钩部，部分与框架重叠。

摘要： A gear mechanism and webbing retractor having a compact size in which a pinion is prevented from being damaged when a large initial driving force is applied from a gear. When a sensor detects an emergent deceleration of a vehicle, a piston driving device is actuated so as to move a rack at its standby position in a direction to a pinion. When the rack is located at the standby position, a tooth face on a side near a front end, of a front end tooth thereof is in contact with a pressure receiving surface of the initially driving member. The rack is moved along a pitch line in the direction to the pinion so that the front end tooth presses the pressure receiving surface. As a result, the initially driving member converts the initial driving force from the rack to a rotation force thereby rotating the pinion in the taking-up direction.

摘要： A webbing take-up device that can prevent unintended and unnecessary switching from an ELR mode to an ALR mode. In a webbing take-up device, a cam protrusion and a tongue portion are provided at a cam member that interlocks with a take-up shaft, and a breaking operational portion and an intermediate holding surface are provided at a disc control member. When a switch is made from the ELR mode to the ALR mode, unwinding and taking-up operations of the webbing are each preformed twice in succession so that the webbing take-up device is switched to the ALR mode, in which an ALR pawl engages with an outer-tooth ratchet wheel of a locking wheel. Accordingly, unless the aformentioned switching is carried out by conscious volition of a vehicle occupant, unintended and unnecessary switching from the ELR mode to the ALR mode does not occur.

摘要： A webbing take-up device is provided capable of preventing or suppressing a frame from deforming such that one of leg-plates or a back-plate displaces towards the other. A face on the center of curvature side of a curved portion of a front back plate section configuring the frame and a one width direction edge namely an upper edge of a bar support face each other along the up-low direction. When the front edge sides of leg-plates are displaced to rise due to a webbing being pulled, the one width direction edge of the bar support interferes with a front end of the front back plate section to prevent or suppress the front edge sides of the leg-plates from rising further. Deformation of the frame caused by the front edge sides of the leg-plates to rise can accordingly be prevented or suppressed.

摘要： By adjusting phases of a webbing sensor and a locking mechanism when a spool locking section operates, special precision and rigidity are not required of respective members, and operation is stabilized. In a webbing retractor, at a time when a lock pawl meshes with a ratchet tooth of a ratchet member, if the lock pawl meshes with an Nth ratchet tooth and a sensor pawl meshes with an (N−1)st internal tooth, a release pawl is moved from a restraining position to a restraint cancelled position against urging force of a torsion coil spring and due to torque in a clockwise direction which teeth surfaces generate. When a gear ring rotates to a position at which a phase difference with the ratchet member substantially disappears, the release pawl is returned to the restraining position by the urging force of the torsion coil spring.
