Abstract
This invention is an impact energy absorption device, in which a long part () 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 () are connected with columns () through upper platens () covering the upper faces of the columns () kept standing apart from each other with a predetermined distance (L), comprising a structural system, in which a deformation of the long part () caused by the impact force applied to it, causes the upper platens () to move for compressing or deflecting the columns (), 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.
