Abstract
Abstract A bumper assembly for a motor vehicle includes a pair of movable side bumpers adapted to be received by the sides of the automobile. A movable rear and forward bumper are joined in tandem to each other. A pair of first bumper rods welded to the forward bumper extend rearwardly into a pair of channel bar members affixed onto the frame of the motor vehicle. A pair of second bumper rods welded to the rear bumper extend forwardly into the channel bar member. A shock absorbing mechanism communicates between each set of first and second rod within each said channel bar member.
