(EN) A hollow member implements, with high mass efficiency,the absorption of energy at the time of a load input. 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 withthe 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.
(ZH) 一种中空的部件,以高的质量效率实现载荷输入时的能量吸收。该中空的部件具备:中空的金属部件,在长度方向的一部分具有弯曲引起部;以及树脂件,与上述金属部件密接,被配置在上述弯曲引起部的上述长度方向的两侧,且配置在上述长度方向上从上述弯曲引起部的端部朝向外侧而不到上述金属部件的截面高度的6分之5的范围的至少一部分;关于上述长度方向的每单位长度的上述树脂件的量,上述弯曲引起部的外侧比上述弯曲引起部的内侧大。
