ABSTRACT:
A movable bumper used on a load carrying vehicle such as an eighteen wheeler truck-trailer. The three bumpers sections are connected together with the upper section having a one-way hinged connection and biasing springs with pulley/cable connectors. When the bumper's lower section is struck by an obstruction with sufficient impact, that section and a connected vertical support section pivot upwardly and outwardly out of the way on the hinged connection against the biasing action of the upper section's springs and connected pulleys/cables. After the obstruction is removed, the bumpers two lower sections return to their normally vertical disposed positions. Support struts with internal springs may be used as additional bumper support and protection between the bumper and the vehicle's or trailer's undercarriage.
