- 衝突荷重が入力される荷重入力部と衝突荷重が伝達される荷重伝達部との間に介在されて軸方向に圧縮変形することにより衝突時のエネルギーを吸収する車両の衝撃吸収部材であって、
前記衝撃吸収部材は、全体として複数の筒状部が軸直角方向に並列的に配置された筒状部の複合体として構成されており、更に軸方向の一端部は閉止されて荷重入力部へ結合される底部とされかつ軸方向の他端部は開放されて荷重伝達部へ結合されるフランジ部が周囲に形成されており、
さらに、前記衝撃吸収部材の底部における筒状部を構成する壁が集まる部位の厚さを、当該底部の他の部位の厚さよりも薄く設定した、
ことを特徴とする車両の衝撃吸収部材。 - 前記底部の他の部位と前記底部における筒状部を構成する壁が集まる部位との段差は、衝突初期のピーク荷重が発生するストロークに対応する高さに設定されている、
ことを特徴とする請求項1記載の車両の衝撃吸収部材。 - 前記底部の他の部位に、荷重入力部への取付部が設定されている、
ことを特徴とする請求項1又は請求項2記載の車両の衝撃吸収部材。
