SHOCK ABSORBING MEMBER
Document Type and Number:
WIPO Patent Application WO/2013/022001
Kind Code:
A1
Abstract:
A hollow, columnar shock absorbing member (1) having an axis line (O), a plurality of rectangular walls (1a, 1b, 1c, 1d) extending parallel to the axis line, and a polygonal cross-section perpendicular to the axis line (O), said shock absorbing member (1) extending in the direction of the axis line (O) and absorbing externally-applied impact energy while buckling in the direction of the axis line (O). The shock absorbing member (1) is provided with at least one bead (2a, 2b, 2c, 2d) formed on at least one wall (1a, 1b, 1c, 1d) among the plurality of walls (1a, 1b, 1c, 1d), said at least one bead (2a, 2b, 2c, 2d) providing the origin of the buckling. The at least one bead (2a, 2b, 2c, 2d) is arranged so as to be biased towards one edge extending parallel to the axis line (O) of the wall (1a, 1b, 1c, 1d) on which the bead (2a, 2b, 2c, 2d) is formed.
