Abstract

A rear roof frame of a motor vehicle has a tailgate which is fastened to the roof frame and includes an upper shell and a lower shell which is fitted to the latter. For the design of a rear roof frame, which, in spite of the shell-type construction, provides, in a simple manner and lightweight construction, sufficient torsional and flexural stiffness in order to withstand high mechanical stresses, it is proposed to arrange within the shell structure a hollow profile which leads in each case from the transition region to the lateral roof frame and parallel to the longitudinal extent of the structure, and emerges, at least at the end facing away from the lateral roof frame, in a knee which kinks in the front-end direction of the vehicle. The end of the rear roof frame forms a tubular hollow profile of the lateral roof frame, which is connected to the hollow profile of the rear roof frame.
