Load path-optimized hybrid support structure

A hybrid support structure for a backrest part of a vehicle seat or a back bench seat, which is formed from a metal structure and a plastic structure, the metal structure including at least one connecting profile disposed between two side rail profiles of the hybrid support structure. It is provided that the connecting profile, together with a central rib of a web structure designed as a plastic structure follows a load path-optimized main load line, which runs between two connecting points of the connecting profile on the side rail profiles, taking into account a force acting upon the hybrid support structure in at least one assumed load case.
