Claim:
A structural door module for a motor vehicle door body, comprising, a carrier plate forming a first and second surface; a plurality of door hardware components mounted to at least one of the first and second surface in a pre-configured orientation; an arm rest support integrally formed from the first and second surface and extending out from the first surface of the carrier plate and forming a hollow in the second surface, said arm rest support including an array of crumple zones formed in the first and second surface and spaced apart around the arm rest support so that the arm rest support collapses into the hollow when subjected to compression forces greater than a predefined force; and an energy absorption block integrally formed from the first and second surfaces of the carrier plate, said energy absorption block including a plurality of terraced portions spaced apart by wall portions between the first and second surfaces and arranged so that the plurality of terraced portions connected by the wall portions form a hollow on the first surface of the carrier plate, and at least one of the terraced portions collapse into the hollow in an opposite direction from that of the arm rest support when subjected to compression forces greater than a predefined force.
