Shock absorbing member and bumper
First Claim
1. A shock absorbing member for a vehicle which absorbs impact energy in a plastic deformation manner to absorb an axial compressive load, comprising a hollow structure having a constant cross section and an axis adapted to extend forward and rearward of the vehicle, the hollow structure having an interior divided into a plurality of separate square-shaped hollow portions, the hollow structure of the shock absorbing member being provided with a flange having a tapered portion so that the axial compressive load is increased gradually in response to advance of the plastic deformation.

Abstract
A shock absorbing member for a vehicle is designed to absorb the impact energy in a plastic deformation manner to absorb the axial compressive load. The shock absorbing member includes a hollow member whose cross-section is roughly constant and whose axis is adapted to extend forward and rearward of the vehicle. A flange is formed on the hollow member roughly along the axis of the hollow member and projects by an amount increasing gradually from one side toward the other side of the axis.

13. A bumper for a vehicle comprising:
-
a bumper reinforcing member;
a body;
a pair of hollow crash boxes each of which is adapted to extend forward and rearward of the vehicle and each of which has a constant cross section, each of the crash boxes having one end fixed to the bumper reinforcing member and an opposite end fixed to the body, the hollow crash boxes each having one end side and an opposite end side, each of the hollow crash boxes being provided with a flange projecting by an amount that gradually increases from the one end side of the hollow crash box toward the opposite end side of the hollow crash box. - View Dependent Claims (14, 15, 16, 17, 18)
