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 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： When disassembling after a gas being supplied into a tube member, the gas in the tube member is discharged before the tube member and a moving member become separable. In a webbing take-up device, a cover plate cannot be removed from a frame and thereafter a cylinder and a piston inside the cylinder cannot be separated before covering of a fixing screw with a covering section of a plate being released by removing a screw from an exhaust port of the cylinder and by removing the plate from the cylinder. Thus, after a high-pressure gas being supplied into the cylinder, the high-pressure gas inside the cylinder can surely be discharged by removing the plate from the cylinder and the exhaust port is opened by the screw before the cylinder and the piston being separated.

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.
摘要翻译：在卷绕卷收器中，电线通过卷轴的通孔插入，在该卷轴的通孔上卷绕有织带，并且织带被拉出。在吸收车辆乘员惯性能的过程的初始阶段，通过将通孔的周边部分的线的摩擦力与扭杆的扭转载荷相加来产生大的限制力载荷。使能量吸收量大，并且将织带的拉出量保持为低。在吸收了预定量的能量之后，当线从通孔完全拉出时，线的摩擦力被消除，力限制器负载减小，并且经由织带施加到车辆乘员的力降低了。

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.
摘要翻译：本发明的目的是获得一种加速度传感器，其能够在倾斜构件的倾斜在固定范围内时可靠地检测加速度，并且能够减少倾斜构件的倾斜度在该范围之外的有关构件的不必要的移动，使得内部的空间效率高。在本发明中，固定在座垫上的固定齿轮的齿轮仅在圆周方向上形成，而没有形成齿轮的部分是滑动面。旋转齿轮的小齿轮的多个齿中的一个齿较短，以形成切口齿部。在座椅靠前的倒塌角度超过预定角度的状态下，切口齿部分面向滑动面并且旋转齿轮体不再旋转。此时，由于安装传感器球的支架也不旋转，所以支架相对于框架板保持在固定位置。因此，考虑到支架的旋转而形成在框架板中的空间不需要很大，空间效率高。
