Abstract
In a light-metal vehicle body, a girder assembly joins a first longitudinal girder member located in a forecarriage region of the vehicle body to a second, laterally offset, and generally longitudinally oriented side sill member. The girder assembly includes a pair of open shell-shaped, light-metal castings which form a single, hollow section enclosure when brought together along their mutual open face regions. The concave interior surfaces of the shell-shaped casting are provided with a plurality of spaced integrally formed stiffening rib members. The stiffening ribs are oriented transverse to the curving longitudinal center axis of the girder assembly which curves in conformance with the Z-shape configuration. The stiffening ribs of each shell-shaped castings are arranged in coordinate pairs such that they formed a series of substantially continuous webs along an interior cross section of said girder assembly. The invention functions to resist plastic deformation of the girder assembly and collapse of said hollow section enclosure in the event of an impact to the vehicle.
