Abstract
A door structure for a vehicle has a door seated in a door jam frame at the rear end of the vehicle. The door jam fame has a first upright with an opening therein disposed nearby one side of the vehicle to provide a space between this side and the first upright. A second upright is nearby the other side of the vehicle. A hinge member is attached to the door which includes a first connecting member attached to the door member near the one side of the vehicle, a second connecting member pivotally attached to the first upright and disposed in the space between the one side of the vehicle and the first upright, and an intermediate arcuate member connected between the first and second connecting members which extends through the opening in the first upright.
