A skeletal load-bearing structure for a motor vehicle includes a plurality of tubular girders joined together by connectors. Each girder and each connector is composed of at least two shell elements of thin sheet metal provided with longitudinal flanges by means of which the shell elements are joined together. Each connector shell element has a plurality of smoothly merging arm portions which together with corresponding portions of the other shell elements of the same connector form a plurality of tubular connection stubs to which respective ones of said girders are connected. |
