ABSTRACT:
An automobile body reinforcement including a hollow aluminum alloy extrusion having an approximately rectangular cross-section is structured as follows: (a) a front wall, a rear wall, an upper horizontal wall, a lower horizontal wall, and an intermediate horizontal wall are provided; (b) the front and rear walls are each at least 3 mm thick; (c) the upper and lower horizontal walls divide each of the front and rear walls thereby defining upper and lower end portions of each of the front and rear walls as flange portions; and (d) the front wall has a concave portion formed in a middle portion thereof and the concave portion is connected to a front end of the intermediate wall. The aluminum alloy automobile body reinforcement structured as described above that may be, for example, a bumper reinforcement or a door guard bar has high bending crush characteristics, for example, high bending strength and high energy absorbability against the bending load generated at a time of a vehicle collision and can provide high collision safety without requiring an additional reinforcement.
