    • A seat belt winding apparatus with a rotation detection unit, for detecting a rotation of a belt winder shaft, and a driving unit, controlled by a detection signal from the rotation detection unit so as to apply a winding force to the belt winder shaft.When the seat belt is pulled by a passenger and a buckle is coupled with a tongue, the driving unit is controlled so that a rotational position of the belt winder shaft in a winding termination state is stored in a storage unit as a reference rotational position, thus establishing a correspondence between a reference rotational position and a count in the storage unit.In the belt fastened state, when the rotational position of the belt winder shaft is shifted from the reference rotational position, the shifted rotational position of the belt winder shaft is compared with the reference rotational position. The belt winder shaft is driven by the driving unit in accordance with the comparison result so as to return the belt winder shaft to the reference rotational position in the belt fastening state. Meanwhile, when the rotational position of the belt winder shaft is shifted from the reference rotational position by the pull-out operation of the seat belt in the condition that the seat belt is not worn by the passenger and the tongue and buckle are not coupled, the winder shaft is driven only in a winding direction so as to return to a reference rotational position in the retracted state.
    • 一种安全带卷绕装置,具有用于检测带卷绕轴的旋转的旋转检测单元和由来自旋转检测单元的检测信号控制的驱动单元,以便向卷绕机轴施加卷绕力。 当安全带被乘客拉动并且带扣与舌头联接时,控制驱动单元,使得绕线终止状态下的带卷绕轴的旋转位置被存储在作为参考旋转位置的存储单元中, 从而建立存储单元中的参考旋转位置和计数之间的对应关系。 在带紧固状态下,当带卷绕轴的旋转位置从基准旋转位置偏移时,将带卷绕轴的移位旋转位置与基准旋转位置进行比较。 根据比较结果,带式卷取机轴由驱动单元驱动,以便在带紧固状态下将带卷绕机轴返回到基准旋转位置。 同时,当安全带未被乘客佩戴并且舌扣没有连接的情况下,通过安全带的拉出操作,当带卷绕器轴的旋转位置从基准旋转位置偏移时, 卷绕轴仅在卷绕方向上被驱动,以便在缩回状态下返回到基准旋转位置。

    • A retractable safety belt system for restraining a vehicle occupant in a seat comprising a seat belt secured at one end to a reel of an electric-motor driven retractor. The retractor motor is controlled by control means (9) having a drive circuit (92G) and a reverse rotation or protraction rotation detection circuit (94A) which senses the reverse rotation of the motor as the seat belt is protracted and energizes the motor to retract the seat belt, thereby removing any slack in the seat belt. Preferably, the control means includes an increasing voltage circuit (94C) for gradually increasing the voltage applied to the motor, thereby reducing the motor torque at the initial stage of retraction. Also, the control means preferably includes a load sensing circuit (94B) which de-energizes the motor as the load on the motor and, hence, the tension in the seat belt reaches a predetermined level.

    • A safety seatbelt retractor for use in a vehicle including a frame adapted to be fixed to the vehicle and a winding shaft rotatably mounted on the frame. The seatbelt is normally wound around the winding shaft. The winding shaft has associated therewith a spring member. When the seatbelt is unwound out of the winding shaft, the spring member applies no or weak biasing force to the winding shaft in such direction as to cause the seatbelt to be wound therearound. During the normal fastening of the seatbelt on a passenger taking his seat of the vehicle, the spring member continuously applies a weak biasing force to the winding shaft in the direction mentioned above. The winding shaft has also associated therewith a drive unit which, when operated, drives the winding shaft to rotate the same so as to cause the seatbelt to be wound around the winding shaft. The drive unit is operated when the seatbelt is unfastened or the passenger gets off the vehicle with the seatbelt unwound out of the winding shaft.
    • 一种用于车辆的安全安全带卷收器,包括适于固定在车辆上的框架和可旋转地安装在框架上的卷绕轴。 安全带通常缠绕在卷轴上。 卷绕轴具有弹簧构件。 当安全带从缠绕轴上展开时,弹簧构件沿着使安全带缠绕在其周围的方向向卷绕轴施加无或弱的偏压力。 在安全带正常地紧固在乘坐车辆座位的乘客上时,弹簧构件沿着上述方向连续地向卷绕轴施加弱的偏压力。 卷绕轴还具有驱动单元,驱动单元在操作时驱动卷绕轴旋转,以使安全带卷绕在卷绕轴上。 当安全带松开时,驱动单元被操作,或者乘客在将安全带从绕轴上展开的情况下离开车辆。

    • A seat belt tensioning device for a vehicle comprises a cylinder, a piston which is slidably inserted within the cylinder and a piston operating means.The piston is composed of a first and a second cylindrical piston members which are adjacent to each other.The seat belt tensioning device further comprises a rod which is connected to a seat belt and is contacted with the second piston member by passing a deformable member, which is plastically deformed by a predetermined tension force through the first piston member. The deformable member is disposed adjacent to the second piston member and connected to the rod by passing through the first and second members.The rod and the second piston member form a conical continuously inclined surface of which diameter is enlarged in the piston moving direction near the contact portion thereof. Stopper pieces having a sharp end portion are radially supported by the conical continuously inclined surface.When the tension force of the seat belt exceeds the plastically deforming load of the deformable member at an urgent time, such as upon a vehicle impact, the deformable member is plastically deformed by the second piston member and elongated and the stopper pieces are lifted up by the taper portion of the second piston member to cut into the cylinder.As a result, the piston is locked in the cylinder and the kinetic energy of the passenger can be absorbed.Therefore, the passenger is prevented from the secondary impact and the injury due to the tensioned seat belt.
