Abstract
A collision energy-absorbing device includes a body member connected between the frame assembly of a motor vehicle and a bumper beam. The body member collapses as the bumper beam and the frame assembly are moved relatively toward one another during a vehicle collision. The body member has a first telescoping portion and a second telescoping portion that are connected by a connecting portion. The telescoping portions have different cross-sectional dimensions to enable the telescoping portions to move one within the other into collapsing telescoping relation as the body member collapses with the connecting portion being deformed and received between the telescoping portions. One or more protrusions extending from one of the telescoping portions interfere with relative movement of the other of the telescoping portions to retard movement of the telescoping portions into telescoping relation.
