Abstract
Abstract A vehicle bumper impact assembly includes a guide cylinder carried by the vehicle frame, and an impact cylinder slidable within the guide cylinder and securable to the bumper at its outer end. A coil compression spring and a fluid type shock absorber unit are disposed between the guide cylinder and the impact cylinder to resist inward movement of the impact cylinder. An abutment is positioned on the frame to limit inward travel of the impact cylinder and to provide means for mounting the coil spring and the shock absorber unit.
