Date Nov. 15, 1990.A structure for forming hollow beams within a car body. The beams are stiffened in their transverse direction by means of cross frames. The cross frames may have a tubular member arranged transversely to the axial length. At one end there may be provided at least partially formed side flanges which are firmly attached to the beam. The length of the tubular member is preferably at least slightly shorter than the distance between the opposite longitudinal sides forming a free space between the other end of the tubular member and one of the longitudinal sides of the beam. |
