PURPOSE: A crash energy absorbing apparatus of a vehicle including plural crash energy absorbing steps is provided to absorb the collision energy which is suitable for the low speed and high speed collision. CONSTITUTION: An impact of a vehicle energy absorption apparatus(100) having a plurality of collision energy absorption steps comprises a first and a second deformable units(120,110) and a pipe expanding unit(130). The first transformation is firstly plastic-deformed by an expansion of a pipe in order to absorb the collision energy. The second deformable unit is arranged in an end part and the extension line of the first transformation part. The second deformable unit is secondly plastic-deformed after first deforming of the fist deformable unit, in order to successively absorb the collision energy. |
