    • In a structure for absorbing energy in an upper portion of a motor vehicle body, an energy absorbing body is disposed between a roof side rail and a roof lining. The energy absorbing body is a resin-made rib member having three longitudinal ribs and transverse ribs that are more in number than the longitudinal ribs. The three longitudinal ribs are formed so as to compensate for a reduced amount of displacement that is allowed for a longitudinal rib for a purpose of energy absorption in a section of the energy absorbing body taken on an imaginary plane extending along at least one of the transverse ribs, by varying at least one of a pitch between two longitudinal ribs provided adjacent to each other in the section, an angle formed by each longitudinal rib with respect to an imaginary horizontal plane in the section, and a thickness of each longitudinal rib.
    • 在机动车身的上部吸收能量的结构中,能量吸收体设置在屋顶侧轨道与车顶衬里之间。 能量吸收体是具有三个纵向肋和横向肋的树脂制肋构件,其数量多于纵向肋。 三个纵向肋形成为补偿减少的位移量,其允许纵向肋用于吸收能量的部分中的能量吸收体的部分,该能量吸收体沿着假想平面延伸,该假想平面沿着至少一个横向 通过改变在该部分中彼此相邻设置的两个纵向肋之间的间距中的至少一个,每个纵向肋相对于该截面中的假想水平面形成的角度以及每个纵向肋的厚度中的至少一个。
