Abstract
A contoured frame member or other car body parts for car bodies of motor vehicles, particularly convertibles, for which the contoured frame member or the car body part bounds a cavity reinforced with a foamed metallic foam material, is formed in such a manner that a structural component is disposed in the interior of the cavity extending in the longitudinal direction of the latter, and in that the foamed metallic foam material occupies the space between the inner wall of the contoured frame member and the structural component lying therein. The internal cavity in the longitudinal direction, has partial regions filled with reinforcing parts of a metallic foam material and, between individual, reinforced regions, remaining hollow regions, the reinforcing parts being connected with the inner walls of the chassis part by way of metallic bonding. A method is also provided for reinforcing regions of car body parts, particularly of components of the type named above.
