PROBLEM TO BE SOLVED: To provide an impact absorbing structure in which a peaky bottoming load is not generated at a later stage of a collision, and can obtain a stable impact absorbing characteristic even if loads are applied to a plurality of protrusions from an oblique direction.SOLUTION: An impact absorbing structure S for use in impact absorption in a vehicle comprises: a first impact absorbing material 1 in which a plurality of protrusions 12 having rib-shaped forms which are erected in a prescribed direction are aligned at intervals; and a second impact absorbing material 2 which has a bar shape or a long-length shape extending along a plurality of recesses 13a, 13b between a plurality of the protrusions 12, and is fit into a plurality of the recesses 13a, 13b so as to be capable of suppressing falls of a plurality of the protrusions 12.
【課題】衝突後期にピーキーな底付き荷重が発生することなく、かつ複数の突起部に斜め方向から荷重が作用したような場合であっても安定した衝撃吸収特性が得られる衝撃吸収構造を提供する。【解決手段】車両における衝撃吸収に用いられる衝撃吸収構造Sであって、所定方向に起立したリブ状の形態をもつ複数の突起部12が間隔を隔てて並んだ状態に設けられた第1の衝撃吸収部材1と、複数の突起部12の相互間の複数の凹部13a,13bに沿って延びたバー状または長尺状の形態を有し、かつ複数の突起部12の倒れを抑制することが可能に複数の凹部13a,13bに嵌入されている第2の衝撃吸収部材2と、を備えている。【選択図】 図1
