Abstract
A bumper bar construction, as for use with automobiles to absorb collision impact energies, has a closed trapezoidal cross-sectional shape. The bumper bar construction includes a broad flange on one broad side of the trapezium and a narrow flange on the opposite, narrow side of the trapezium. The broad and narrow flanges extend generally in mutually parallel planes. The bumper bar construction further includes two mutually convergent webs which join the two flanges together.
