Abstract
A bumper beam construction including an elongated tubular beam of high strength but characteristically flexible to absorb substantial energy on impact having a mounting bracket attached at each end of the center section and at least one stiffening bracket attached to each mounting bracket. The mounting brackets extend from the rear wall of the tubular beam and facilitate attachment to a vehicle frame. The stiffening brackets are attached to the mounting brackets and the end sections of the tubular beam outboard of the center section. The stiffening brackets improve the comer impact strength of the tubular beam without adversely affecting the flexibility of the center section. This comer construction arrangement provides for optimal distribution of stress during corner impacts.
