摘要： This invention is an impact energy absorption device, in which a long part (1) made of a high strength material is disposed with its lengthwise direction kept different from an impact direction, and both terminals of the long part (1) are connected with columns (2) through upper platens (3) covering the upper faces of the columns (2) kept standing apart from each other with a predetermined distance (L), comprising a structural system, in which a deformation of the long part (1) caused by the impact force applied to it, causes the upper platens (3) to move for compressing or deflecting the columns (2), thereby absorbing the impact energy.
The conventional column type energy absorption member is weak against an impact applied in a direction within a wide angle (θ) such as an impact applied in an oblique direction. However, the energy absorption device of this invention can exhibit an impact energy absorption capability even against an impact applied in the direction within such a wide angle, equivalent or superior to that in the case where it fails in the axial direction. Furthermore, even if the parts used are damaged, they can be easily exchanged to allow restoration as an energy absorption device.摘要翻译： 本发明是一种冲击能量吸收装置，其中由高强度材料制成的长部分（1）的长度方向保持不同于冲击方向，并且长部分（1）的两个端子与柱 （2）通过覆盖柱（2）的上表面的上压板（3）以预定距离（L）保持彼此分离，包括结构系统，其中引起长部件（1）的变形 通过施加到其上的冲击力，使上压板（3）移动以压缩或偏转柱（2），从而吸收冲击能量。 传统的列式能量吸收构件对于在倾斜方向上施加的冲击方向上施加的广角（...）方向上的冲击较弱。 然而，本发明的能量吸收装置即使在如此广角度的方向上也能够表现出冲击能量吸收能力，等同于或优于其在轴向方向上失效的情况下的冲击能量吸收能力。 此外，即使所使用的部件被损坏，它们可以容易地更换以允许作为能量吸收装置的恢复。
