Bulkhead assembly for vehicles

A bulkhead assembly for a vehicle such as, for example, a van or truck comprises a first panel adjacent and substantially perpendicular to a street-side wall of the vehicle, a second panel adjacent and substantially perpendicular to a curb-side wall of the vehicle, and a door panel disposed between the first and second panels, the door being hingedly attached to one of the first and second panels, wherein the panels are formed from a polymer material. In one embodiment, the panel adjacent the street-side wall of the vehicle (i.e., the driver-side panel) defines a cavity extending rearwardly into the cargo area, the cavity being sized (in terms of the cavity's width) to accommodate the seat-back of the driver's seat.
