IMPACT ABSORPTION MEMBER
Document Type and Number:
Japanese Patent JP2023167947
Kind Code:
A
Abstract:
To provide an impact absorption member which can suppress the reduction of an absorbable impact energy.SOLUTION: An impact absorption member comprises a cylinder body 11 whose cross section is formed into a polygonal shape. The cylinder body 11 has a closed space therein by welding edges by folding a metal plate 13 at a plurality of points. A reinforcing part 14 extending along a plurality of ridge lines of the cylinder body 11 is arranged on the ridge lines. When an impact is imposed in a direction in which a center line of the cylinder body 11 extends, the impact absorption member absorbs the impact energy through the buckling of the cylinder body 11. On the ridge lines located adjacent to a point in which the edges of the metal plates 13 in the cylinder body 11 are joined, the reinforcing parts 14 are not present, and these areas serve as unreinforced parts 15.SELECTED DRAWING: Figure 1
