摘要： A method of forming a vehicle component, particularly an elongated impact beam, having an open section structure, in a manner to provide predetermined strategically strengthened portions, comprising the steps of cold forming unhardened steel into a workpiece having mounting surfaces, selectively fixturing the mounting surfaces, static induction heating the workpiece with lengthwise surface eddy currents on selected portions, followed by quenching of the fixtured heated workpiece to form strengthened portions, and unfixturing the resulting component. Also disclosed is apparatus to accomplish this, and the resulting novel vehicle component.

摘要： A vehicle door impact beam having an elongated tubular body with a central axis, the end portions of the beam being taper cut to form inner and outer termini and opposite taper surfaces for each end, the included angle at the inner termini being greater than 180 degrees and the outer termini being less than 180 degrees, and the first and second taper surfaces each spiraling from the inner terminus to the outer terminus through an angle of about 90 degrees. The inner termini of both ends are on opposite sides of the beam, and the outer termini of both ends are on the same side of the beam.

摘要： A channeled energy absorption unit for a vehicle bumper impact system to absorb impact energy and forestall or minimize damage to vehicle frame rails under impact. The basic embodiment is a tube with one end flared and welded at a hole in one end plate or directly to the vehicle frame rail. When loaded axially, the tube splits, peels and is inverted to absorb impact in a generally square wave energy absorption. Preferred channels in the tube stabilize the failure mode during this process to assure a predetermined energy absorption characteristic.
