A vehicular door hinge mechanism imparting a two dimensional motion to the door as it opens or closes, the present mechanism provides for a motion in two different directions at two different portions of the door's motion cycle. The present invention provides a hinge which allows the door of the vehicle to move outwards in a substantially horizontal plane for a predetermined arc, then move vertically upwards on another predetermined arc thereafter. The invention comprises a hinge mechanism having a chassis mounting plate and a swingarm. Between them is either a pivotal bearing or a hinge designed to allow the staged two dimensional motion of the invention. A spring or cylinder is connected at its ends to the chassis mounting plate and the swingarm. A horizontal pressure bearing surface and a cam adjuster cooperate to provide strength and precise fit of the door with the vehicle. The invention provides a method of opening a vehicle door in a doorway of a vehicle body, the method comprising: rotating such vehicle door in a horizontal plane of motion until such vehicle door substantially clears such vehicle body; and then rotating such vehicle door in a vertical plane of motion until such vehicle door substantially clears such door way. The invention may be easily retrofitted to existing vehicles or factory installed.
