Abstract
(EN)
[Problem] To implement, with high mass efficiency, absorption of energy 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 resin members which are disposed on both sides, in the longitudinal direction, of the bending induction part so as to be in close contact with the metal member, and which are disposed within at least a portion of the range of less than five sixths of the cross sectional height of the metal member so as to each extend from an end of the bending induction part toward the outside in the longitudinal direction, wherein the amount of the resin members on the outer side of the bending induction part is larger, per longitudinal length, than that of the resin members on the inner side of the bending induction part.

Le problème décrit par la présente invention est de mettre en œuvre, avec une efficacité de masse élevée, une 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 des éléments de résine qui sont disposés sur les deux côtés, dans la direction longitudinale, de la partie d'induction de flexion de façon à être en contact étroit avec l'élément métallique, et qui sont disposés à l'intérieur d'au moins une partie de la plage inférieure à cinq sixièmes de la hauteur de section transversale de l'élément métallique de façon à s'étendre chacun à partir d'une extrémité de la partie d'induction de flexion vers l'extérieur dans la direction longitudinale, la quantité des éléments de résine sur le côté externe de la partie d'induction de flexion étant plus grande, par longueur longitudinale, que celle des éléments de résine sur le côté interne de la partie d'induction de flexion.
