Abstract
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.
Claims16
A hybrid support structure for a backrest part of a vehicle seat or a vehicle back bench seat, the hybrid support structure comprising:
- a metal structure including a connecting profile disposed between a first side rail profile and a second side rail profile, the connecting profile connected to the first side rail profile at a first connecting point and connected to the second side rail profile at a second connecting point;
- and
- a plastic structure, the plastic structure including a web structure having a central rib,
- wherein the first side rail profile is parallel to the second side rail profile and the connecting profile extends diagonally between the first side rail profile and the second side rail profile,
- wherein the connecting profile and the central rib extend along a same line, the same line being a load path-optimized main load line which runs between the first and second connecting points.
