Abstract
A motor vehicle chassis is disclosed wherein a conventionally hinged door is integrated with and becomes a structural part of the main chassis when the door is closed. Wedge-shaped structural keys located on the forward and rearward edges of the door engage mating receptacles on the door jamb to transmit compressive, tensile, and torsional forces across the door opening when the door is closed. Preferably, the door hinges are separated when the door is closed so that all forces are transmitted through the keys and receptacles without interference from the hinges. The inventive technology can also be used with other vehicle door panels such as sliding side van doors, hoods, trunks, liftgates and tailgates to form a stronger, stiffer vehicle chassis that is less susceptible to deformation during impact.
