摘要： There is provided a webbing take-up device in which a load required to rotate a spool in a webbing drawing direction with reference to a shaft is stabilized in the process of rotating the spool, a stable load can be achieved with small deformation, and miniaturization can be achieved. In an ordinary state, an EA plate keeps its original shape, and the shaft and spool are rotated together with each other. When the shaft is prevented from being rotated in the webbing drawing direction in vehicle sudden deceleration, the EA plate is plastically deformed by a webbing drawing force, and the EA plate is pushed in an internal-angle portion of the spool with rotation of the spool in the webbing drawing direction with reference to the shaft. The EA plate is bent by a U-shaped portion and then wound around the outer periphery of the shaft. The other end portion of the EA plate is pushed into the internal-angle portion at a winding start end portion of the EA plate around the shaft to prevent the subsequential rotation of the spool in the webbing drawing direction with reference to the shaft. Thus, when the webbing is prevented from being drawn, the webbing is drawn by a predetermined length, and energy absorption can be achieved.

摘要： A lever is provided for switching from a state in which a preloader for rapidly rotating a webbing take-up shaft in a webbing winding direction in an emergency of a vehicle is non-operated to a state in which the preloader is operated. Before a retractor is mounted to the vehicle, the preloader is made non-operative so that an undesired operation may be avoided. The lever interlocks with a lock device for preventing the webbing take-up shaft from being rotated in a webbing pulling-out direction during acceleration of the vehicle. When the preloader is in a non-operative state, the lock device provides a locked state in which a webbing cannot be pulled out from the webbing take-up shaft. Therefore, in order to fasten the webbing to an occupant, the lever must be actuated to enable the pulling out of the webbing, i.e., to enable the lock device to operate and to enable the preloader to operate. After the retractor has been mounted to the vehicle, the preloader is released from the non-operating state.

摘要翻译： 提供了一种杠杆，用于从在车辆的紧急情况下使织带卷绕方向上快速旋转的预紧装载机不操作到预加载器运行的状态的状态切换。 在将牵开器安装到车辆之前，预加载器被制造成非操作的，使得可以避免不期望的操作。 杠杆与锁定装置互锁，用于防止织带卷取轴在车辆加速期间沿织带拉出方向旋转。 当预加载器处于非操作状态时，锁定装置提供锁定状态，其中织带不能从织带卷取轴中拉出。 因此，为了将织带固定在乘员身上，杠杆必须被致动以使得能够拉出织带，即使得锁定装置能够操作并使得预加载器能够操作。 在牵开器已经安装到车辆之后，预加载器从非操作状态释放。
