Abstract
A hollow columnar shock absorbing member (1) has an axis (O), a plurality of rectangular walls (1a, 1b, 1c, 1d) extending parallel to axis (O), and a polygonal cross-section perpendicular to axis (O), the shock absorbing member extending in the direction of axis (O) and absorbing externally-applied impact energy while buckling in the direction of axis (O). Shock absorbing member (1) is provided with at least two flanges (2a, 2b, 2c, 2d) protruding from at least two edges (1e, 1f, 1g, 1h) formed by at least two sets of neighboring walls among a plurality of walls, and the at least two flanges are arranged so that the directions of protrusion of the flanges from the edges are directed to the same direction with respect to a circumferential direction.
Claims10
A hollow columnar shock absorbing member having an axis, a plurality of rectangular walls extending parallel to the axis, and a polygonal cross-section perpendicular to the axis, the shock absorbing member extending in the direction of the axis and absorbing externally-applied impact energy while buckling in a direction of the axis,
- wherein the shock absorbing member is provided with at least two flanges protruding from at least two edges formed by at least two sets of neighboring walls among a plurality of walls, and the at least two flanges are arranged so that directions of protrusion of the flanges from the edges are directed to the same direction with respect to a circumferential direction.
A hollow columnar shock absorbing member having an axis and a polygonal cross-section, the shock absorbing member absorbing externally-applied impact energy while buckling in a direction of the axis,
- wherein a buckling inducing portion for determining a direction of inclination is formed on a wall and/or an edge of the shock absorbing member, so that a ridge of each edge is inclined in the same direction with respect to a circumferential direction of the shock absorbing member at the beginning of the buckling, when the shock absorbing member is buckled in the direction of the axis.
