PCT No. PCT/EP91/02264 Sec. 371 Date Jun. 15, 1993 Sec. 102(e) Date Jun. 15, 1993 PCT Filed Nov. 29, 1991 PCT Pub. No. WO92/11158 PCT Pub. Date Jul. 9, 1992.The invention relates to a conical central pillar assembly for the bodywork of a passenger car, especially a bodywork having a space-frame bearing structure constructed from extruded light metal section bearers and cast light metal joining elements. According to the invention, the central pillar assembly includes a substantially plate-like base section wall having a multi-layer, multi-chamber extruded section disposed thereon. The section chambers in the outermost layers are selectively cut at various heights in step wise fashion in order to produce a desired conical cross section with a wide base portion and narrow top portion. Additional cuts are made in the outermost section chambers to form recesses for accommodating door locks, hinge assemblies and the like. An additional piece, preferably in the form of a light metal casting or a sheet metal stamping, is provided and forms an outer cover for at least a bottom portion of the central pillar.
