Abstract:
(EN) [Problem] To improve, with high mass efficiency, an energy absorbing amount at the time of a load input. [Solution] This hollow member is provided with: a hollow metal member which has a bending induction part in a portion thereof in the longitudinal direction; and a resin member which is made from a resin having a Young's modulus of at least 20 MPa and which is disposed at the bending induction part so as to be in close contact with the metal member.
(FR) Le problème décrit par la présente invention est d'améliorer, avec une efficacité de masse élevée, une quantité d'absorption d'énergie au moment d'une entrée de charge. La solution selon l'invention porte sur un élément creux qui est pourvu : d'un élément métallique creux qui a une partie d'induction de flexion dans une partie de celui-ci dans la direction longitudinale ; et un élément en résine constitué d'une résine ayant un module de Young supérieur ou égal à 20 MPa et qui est disposé au niveau de la partie d'induction de flexion de sorte à être en contact étroit avec l'élément métallique.
(JA) 【課題】荷重入力時のエネルギ吸収量を高い質量効率で向上させる。 【解決手段】長手方向の一部に曲げ誘起部を有する、中空の金属部材と、ヤング率20MPa以上の樹脂からなり、前記金属部材に密着して前記曲げ誘起部に配置された樹脂材と、を備える中空の部材。
