Abstract
An energy absorbing apparatus is provided and includes an outer shell having opposed ends, left and right side walls and a hollow core. The shell further includes a plurality of longitudinally spaced apart fold points positioned on the left and right side walls at a height which substantially corresponds to a center of gravity of a road vehicle where the fold points facilitate a controlled folding of the side walls and at least part of the shell, at or around, the fold points, during an end on impact.
