Abstract

To provide an impact absorbing member that can be arranged flexibly in accordance with the shape of the space where the impact absorbing member is to be arranged. An impact absorbing member according to an exemplary aspect has a plurality of structural members each having hollow tetrahedron structures arranged continuously at prescribed intervals on an axis. Further, an impact absorbing member according to another exemplary aspect has a plurality of structural members woven by a connecting member that is disposed in a direction orthogonal to an axial direction of the structural members.

Claims (6)

1. An impact absorbing member comprising a plurality of structural members each having hollow tetrahedron structures arranged continuously at prescribed intervals on an axis, wherein

the plurality of structural members are arranged in parallel and woven by a connecting member that is disposed in a direction orthogonal to an axial direction of the structural members.

2. A method for manufacturing an impact absorbing member comprising:

forming hollow tetrahedron structures continuously at prescribed intervals by alternately crushing a hollow tube vertically and laterally in a tube radial direction; and

arranging, in parallel, a plurality of structural members in which the hollow tetrahedron structures are formed continuously at the prescribed intervals, and weaving the structural members with a connecting member.

3. The method for manufacturing the impact absorbing member according to claim 2 , wherein the hollow tube is made of stainless steel.
