    • An impact energy absorbing mechanism for a steering device of a motor vehicle includes guides each having a generally U-shaped guide surface. Each guide is mounted to a steering column which is movable in the axial direction when the operator's body is thrown out onto a steering wheel due a collision of the vehicle. A retaining portion is provided integrally with the guide and at a predetermined distance from the guide surface. An absorbing plate is fixed at one end to the vehicle body and left free at the other end. The free end of the absorbing plate is inserted and retained in a gap defined between the guide surface and retaining portion of the guide, so that the absorbing plate is held in a generally U-shaped bent position along the guide surface. When the guide is moved together with the steering column, the bent portion of the absorbing plate is sequentially shifted while maintaining the shape which is defined by the guide, thereby absorbing impact energy.
    • 用于机动车辆的转向装置的冲击能量吸收机构包括各自具有大致U形的引导表面的引导件。 每个引导件安装到转向柱上,当转向柱由于车辆的碰撞而将操作者的身体甩出方向盘时,可以沿轴向移动。 保持部分与引导件一体地设置并且与引导表面预定距离。 吸收板一端固定在车体上,另一端固定。 吸收板的自由端被插入并保持在限定在引导件的引导表面和保持部分之间的间隙中,使得吸收板沿着引导表面保持在大致U形的弯曲位置。 当引导件与转向柱一起移动时,吸收板的弯曲部分依次移动,同时保持由引导件限定的形状,从而吸收冲击能量。
