The cross member (1) comprises a base body (2) and reinforcement (3) with at least one wall (22) running transversely to the cross member. The wall is preferably made from sheet metal such as steel, aluminium or magnesium and has an aperture between the wall and base member to provide an air duct e.g. for climate control systems or for wiring systems. The reinforcement has ribs and/or tensile elements. |
