摘要： There is provided a pretensioner which can as a whole be made smaller. A rack and pinion type pretensioner is disposed outside a second leg plate of a webbing take-up device. A driving mechanism of the pretensioner includes, as principal components, a piston formed as a rack bar, and a pinion. The pinion includes a toothed portion and a clutch portion, and is directly connected to a winding shaft. Accordingly, as compared with a conventional system in which intermediate gears are disposed between the pinion and the rack bar, the pretensioner can as a whole be made smaller both in radial and axial directions thereof.

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： In a webbing retractor, a wire is inserted through a through-hole of a spool on which a webbing is taken-up and from which the webbing is pulled-out. At an initial stage of a process of absorbing inertial energy of a vehicle occupant, a large force limiter load is generated by adding a rubbing force of the wire at a peripheral portion of the through-hole, to a twisting load of a torsion bar. An energy absorption amount is made large, and an amount of pulling-out of the webbing is kept low. After a predetermined amount of energy has been absorbed, when the wire is completely pulled-out from the through-hole, the rubbing force of the wire is cancelled, the force limiter load is reduced, and force applied to the vehicle occupant via the webbing is reduced.

摘要： An object of the present invention is to obtain an acceleration sensor that can reliably detect acceleration when inclination of an inclining member is within a fixed range, and that can reduce unnecessary movement of relevant members when inclination of the inclining member is outside of the range, so that space efficiency in an inner portion is high. In the present invention, a gear of a fixed gear fixed at a seat cushion is formed in only a portion in the circumferential direction, and a portion at which the gear is not formed is a sliding surface. One of teeth among a plurality of teeth of a pinion of a revolving gear is short, to form a notched tooth portion. In a state in which the forward-collapsed angle of a seatback exceeds a predetermined angle, the notched tooth portion faces the sliding surface and the revolving gear body no longer rotates. At this time, since a bracket at which a sensor ball is mounted also does not rotate, the bracket is held at a fixed position relative to a frame plate. Accordingly, a space formed in frame plates in consideration of rotation of the bracket does not need to be large, and space efficiency is high.

摘要： In a normal state, a roller is engaged with an engaging projection of a rotor constituting a pretensioner and is not nipped between the rotor and a shaft. Accordingly, the shaft is freely rotated and a spool is also freely rotated so that a webbing can be pulled out and wound up. When a vehicle suddenly decelerates, the rotor is rotated and the engaging projection is separated from the roller. Accordingly, the roller is pushed by a taper of the rotor and is nipped between an outer circumferential face of the shaft and the taper. Since the rotor and the shaft are connected to each other through the roller, the rotation force of the rotor is transmitted to the shaft and the spool is rotated and the webbing is wound. Accordingly, it is possible to provide a webbing winding device in which the rotation force of the pretensioner can be transmitted to the spool without causing resistance in the rotation of the pretensioner at its operating time or wasting the rotation force for rotating the spool.
摘要翻译：在正常状态下，辊与构成预张紧器的转子的接合突起接合，并且不夹在转子和轴之间。因此，轴自由旋转，并且线轴也自由旋转，从而可以拉出并卷绕织带。当车辆突然减速时，转子旋转并且接合突起与辊分离。因此，滚子被转子的锥形推动并被夹在轴的外圆周面与锥形之间。由于转子和轴通过辊彼此连接，转子的旋转力传递到轴，并且卷轴旋转并且织带被卷绕。因此，可以提供一种织带卷绕装置，其中预紧器的旋转力可以传递到卷轴，而不会在预紧器在其运行时间的旋转中产生阻力或浪费用于旋转卷轴的旋转力。

摘要： A plurality of protrusions are formed on an inner peripheral portion of a bearing main body that supports a large diameter shaft portion of a take-up shaft. These protrusions are in line contact with an outer peripheral portion of the large diameter shaft portion, which allows the bearing main body to support the large diameter shaft portion indirectly via the protrusions. As the protrusions are in line contact with the large diameter shaft portion, the contact area is very small and the frictional resistance between the protrusions and the large diameter shaft portion causes the protrusions to undergo plastic deformation easily. Thus, the resistance that hinders the rotation of the large diameter shaft portion is decreased and a share that is served for the rotation of the take-up shaft by the pressure of gas is increased, thereby providing a webbing retractor that can serve efficiently for taking up a webbing belt.

摘要： In the present pretensioner, press contact portions are formed further to a side of an open end of a packing housing section than central portions of opposing faces along a depth direction of the packing housing section. Accordingly, when a packing is being fitted into the packing housing section, no great resistance is imparted to a curved face side of the packing from a press contact wall of a housing section body and the opposing face, and the packing is fitted comparatively smoothly therein. Consequently, even when fitting the packing into the packing housing section, a packing main body is largely resilient-deformed, such that a large collapse in a through hole can be prevented, and the sealing ability of the seal due to deformation of the packing main body can be effectively enhanced.
摘要翻译：在本发明的预张紧器中，沿着包装容纳部的深度方向，与接合面的中央部分相比，在接合部的开口端的另一侧形成有压接部。因此，当将填料装配到填料容纳部中时，不会从容纳部主体的压力接触壁和相对面向衬垫的曲面侧施加大的阻力，并且衬垫相对平滑地配合。因此，即使将密封件装配到包装容纳部中，包装主体大部分弹性变形，能够防止通孔中的大的塌陷，并且密封件由于包装主体的变形而产生的密封性身体可以有效地增强。

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.
