摘要： A lightweight car body energy absorber made of Al alloy which provides a high energy absorption performance. The car body energy absorber comprises a hollow shape with a rectangular sectional profile and a reinforcing shape attached to the front face of the collision plane of the hollow shape, where the hollow shape and the reinforcing shape are aluminum alloy extruded shapes. The reinforcing shape has a hat-shaped open sectional profile, which is composed of a collision wall almost parallel to the collision plane of the hollow shape, plural mutually parallel horizontal ribs which support the collision wall, and vertical flanges provided at the tips of these ribs. The reinforcing shape is joined to the collision plane of the hollow shape through the vertical flanges.
