Single hung self aligning door hinge

A hinge assembly pivotably mounting a vehicle door member to a body structure member about a door swing axis, the hinge assembly comprising:

• a first hinge strap mounted to one of the members and having a vertical opening;
• a second hinge strap mounted to the other member having a spherical concave surface and a hole opening onto the spherical concave surface;
• a hinge pin interposed between the hinge straps and having a spherical convex surface engaging the spherical concave surface of the second hinge strap for allowing a variance in position of the hinge pin to the second hinge strap and the hinge pin having a portion projecting from the spherical convex surface and extending through the hole in the second hinge strap and received in said vertical opening in the first hinge strap and with the hinge pin having a pivot center through which the door swing axis extends;
• a retention means for retaining the spherical convex surface of the hinge pin in engagement with the spherical concave surface of the second hinge strap and allowing relative rotation between the hinge pin and the second hinge strap about the pivot center of the hinge pin;
• said second hinge strap having a cylindrical bore and a plastic bearing carried in the cylindrical bore, said plastic bearing defining said spherical concave surface for said second hinge strap and engaging the spherical convex surface of the hinge pin, said retention means including a bellville washer carried in the cylindrical bore for retaining the spherical convex surface of the hinge pin in engagement with the spherical concave surface of said plastic bearing of the second hinge strap;
• and
• a removable retention bolt for retaining the hinge pin to said first hinge strap whereby the retention bolt allows removable retention of the door member to the body structure member and the concave and convex surfaces allows for variance in relative orientation of the second hinge strap to the door swing axis.
