Abstract
Enclosed and described is a bumper comprising an arched member having an outer wall, an inner wall, a hollow interior between the outer wall and the inner wall, and at least one dividing wall or protrusion dividing at least part of the hollow interior into at least two chambers. The arched member has different cross sections along its length. These cross sections include a first cross section on each side of a central portion of the arched member, which first cross section corresponds to the cross section of a blank from which the beam or bumper is produced. A second cross section is provided at the central portion of the arched member, wherein the second cross section exhibits a region that extends outwardly relative to the first cross section. And, a third cross section is provided adjacent to each terminal end of the arched member, wherein the third cross section is generally the same as the first cross section, or is different from the first cross section such that the first cross section exhibits a region that extends outwardly relative to the third cross section.
