  • Patent number: 5128191
    Abstract: The component comprises an elongate structure (1) with an open cross-section and edge stiffening elements (2); to increase the shear stiffness or bulge resistance of the structure (1), its flanges (3) are stiffened in the deformation-critical areas with plates or shells (4) attached to the flanges by means of spacer elements (7-9).
