摘要： A car trim including a plurality of ribs formed integrally and arranged vertically at a predetermined interval on a predetermined site of the rear face 1a of trim main body 1 for absorbing energy of collision, each rib being formed in a rectangular tube, each rib side wall 4a being tapared with thinning toward its distal end, and a rigidity changing portion P being disposed by integrally forming an auxiliary rib piece 5 on the rib side wall 4a for introducing buckling transformation of the rib 4 at a predetemined position in the rib side wall 4a. The rib also includes a first energy absorbing portion 5 and a second energy absorbing portion 6 formed in such a multi-stepped manner that the number of rib walls in the former step is different from that number in the latter step. Further, the rib also includes a first auxiliary rib piece 5 extending outside from each corner along one side wall 3, 4 of the rib and a second auxiliary rib piece 6 extending from the distal end of the first auxiliary rib piece 5 onto the other side wall 4, 3 vertically intersecting that first auxiliary rib piece.

摘要翻译： 一种轿厢装饰件，其包括一体形成并且以预定间隔竖直布置的装配主体1的后表面1a的预定位置，用于吸收碰撞能量，每个肋形成为矩形管，每个肋侧壁 4a朝向其前端变薄化，并且刚性改变部P通过在肋侧壁4a上一体地形成辅助肋片5而设置，以将肋4引导到肋侧壁4a中的预定位置处的弯曲变形 。 该肋还包括第一能量吸收部分5和第二能量吸收部分6，该第一能量吸收部分6以这样的多步骤形式形成，使得前一步骤中的肋壁的数量与后一步骤中的数量不同。 此外，肋还包括第一辅助肋片5，该第一辅助肋片5从肋部的一个侧壁3,4从每个角部延伸到外侧，以及从第一辅助肋片5的远端延伸到另一侧的第二辅助肋片6 壁4,3垂直相交于第一辅助肋片。
