摘要： A reel of a seat belt retractor equipped in a automobile for reeling a seat belt is integral with a shaft of an ultrasonic motor. The ultrasonic motor is rotated either one direction or the other so as to retract or draw out the seat belt. A control device for controlling the rotation of the ultrasonic motor by supplying a control signal based on the signals sensed by a buckle sensor which senses a buckle is locked, a tension sensor which senses tension of a seat belt, a speed sensor which senses speed of the automobile, a rotation sensor which senses the rotation degree and a child seat sensor which senses whether child seat is set on a passenger seat.

摘要： A tongue cover is attached to a grip of a seatbelt tongue such that the tongue cover covers edges of the grip except for an edge to which a plate is attached. The tongue cover may be formed of synthetic resin or rubber that is softer than a resin mold of the grip. The tongue cover, which acts as a cushion, prevents the grip from directly impacting the trim on the inner side wall of a vehicle, thereby substantially reducing the likelihood that the trim will be scratched and/or dented. Moreover, the tongue cover also substantially reduces and/or eliminates noise that is typically caused when a tongue directly impacts trim on the inner side of a vehicle, in the absence of such a tongue cover.
摘要翻译：舌盖附接到安全带的把手，使得舌盖覆盖除了附接到板的边缘之外的把手的边缘。舌盖可以由比手柄的树脂模具更软的合成树脂或橡胶形成。充当垫子的舌盖防止手柄直接撞击车辆内侧壁上的装饰物，从而大大降低了装饰物将被划伤和/或凹陷的可能性。此外，在没有这样的舌盖的情况下，舌盖还基本上减少和/或消除了当舌头直接冲击车辆内侧上的装饰物时通常引起的噪音。

摘要： A seat belt retractor absorbs impact by deforming a roll made of steel just like reversely rolling up. When acceleration exceeds a threshold for example in the event of vehicle collision, a lock gear is locked by a lock activating mechanism and pawls engage some of internal teeth of a lock base. A webbing is loaded with significantly large tension by the occupant being moved forward due to the acceleration so that extremely large torque is applied to the lock base from the reel through the pawls. Because of this torque, the steel roll plastically deforms just like being reversely rolled up from the inner end so that the webbing is gradually unwound, thereby softening impact acting on the occupant by the webbing.
摘要翻译：安全带卷收器通过使由钢制成的辊变形而像反向卷起一样吸收冲击。当加速度超过例如在车辆碰撞的情况下的阈值时，锁定齿轮被锁定启动机构锁定，并且棘爪接合锁定基座的一些内部齿。由于加速度，乘员由于加速而被向前移动而承受很大的张力，从而通过棘爪将极大的扭矩从卷轴施加到锁定基座。由于这种扭矩，钢辊就像从内端反向卷起而塑性地变形，使得织带逐渐展开，从而软化通过织带作用在乘员身上的冲击。
