ABSTRACT:
A tubular bumper beam includes mounts for mounting to a vehicle frame and a crush cone in front of each mount. Each crush cone includes a flange engaging a front wall of the beam and includes a tube section extending through the front wall into engagement with a rear wall of the beam. A thermoformed energy absorber includes ridges engaging horizontal channels in the face and recesses receiving the flanges of the crush cones. The energy absorber is thermoformed to include crush boxes. At least two crush boxes include adjacent side walls having root sections bonded together near their base walls for increased strength. This is accomplished by scriving and cutting back a leading edge of one of the blade-shaped protrusions, such that the scrived leading edge leaves the root regions exposed so that the root regions bond together while the plastic material is hot.
