Abstract: A vehicle door module including window glass is presented which includes a box section belt having an angled bolt attachment and a double overlap attachment to maintain strength and rigidity of the door assembly. The incorporation of the box section belt to the vehicle door module permits the inclusion of the window glass and various parts of the lift system. The angled bolt attachment provides for efficient load transfer between the belt and the door frame through load sharing face contact and a bolt. The double overlap attachment provides for efficient load transfer through a lap joint and clamping forces provided by a bolt. The double overlap attachment further includes features which facilitate assembly while compensating for manufacturing tolerances and build variability. An embodiment of the double overlap joining includes interlocking ridges which engage to further enhance load transfer capability.
