Title:
COLLISION ENERGY ABSORBING STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2011/126146
Kind Code:
A1
Abstract:
Provided is a collision energy absorbing structure which has a simple structure, and can be formed by pressing, wherein a stable deformed shape can be obtained; a resistance for load in a deformation process is stable at a high level; and the energy absorbing efficiency is high. The collision energy absorbing structure is cylindrical, and changes shape in the axial direction to absorb collision energy. The shape of a section perpendicular to the axial direction is a polygonal shape which is symmetrical with respect to the center of the section, and is not symmetrical with respect to the center line of the section. When the outline of the section has a rectangular shape, the aspect ratio is less than 1.5, and the ratio of the lengths of the adjacent sides among the sides of the polygonal shape constituting the section is 2.3 or less.
