ABSTRACT:
A blow formed, one-piece, hollow bumper includes a bumper body member, and a reinforcing frame member for connection with the vehicle frame. The frame member projects into the hollow inside of the body member from the backside of the body member. The frame member is formed in one piece with the body member attached to a vehicle frame attachment portion of the body member. In one embodiment, the frame member is closed off with a metallic plate member so as to form a box cross section. A method of making the bumper is also disclosed and includes the steps of setting the frame member in a mold and blow forming a bumper member integral with the frame.
