ABSTRACT:
This energy absorber yieldably couples a bumper to support structure on a vehicle and comprises a spring bracket assembly which includes a pair of diverging spring arms which carry pins on the ends thereof. A preloaded yieldable energy absorbing band of resilient plastic material is stretched across the arms, by attachment to the spaced pins. On impact of the bumper, the pins are displaced outwardly from one another as the spring arms are deflected to stretch the energy absorbing band. The deflection of the spring arms and the stretching of the energy absorber absorbs impact energy.
