Door hinge for a motor vehicle door with a braking and retaining function

A door hinge for a motor vehicle door and provided with a braking and retaining function, the door hinge comprising:

• a first hinge half attachable to one of a door and a door pillar;
• a second hinge attachable to another of the door and the door pillar;
• and
• a hinge pin extending through gudgeons of the first and second hinge halves for pivotally connecting the first and second hinge halves together, the hinge pin having generally a regular cylindrical circumferential surface,
• wherein the hinge pin is secured in a gudgeon of one of the first and second hinge halves against rotation and extends through a bore of a gudgeon of another of the first and second hinge halves with a clearance, and
• wherein the hinge pin and the bore of the gudgeon of another of the first and second hinge halves both have, at least along a portion of a common axial extent thereof, complementary, circumferential axially extending regions the circularity of which deviates from a regular circular cross-section of complementary cylindrical surfaces of the hinge pin and the gudgeon bore and which form continuous arcuate surfaces with adjacent associated sections of the complementary cylindrical surfaces of the hinge pin and the gudgeon bore, thereby to insure a smooth continuous increase in resistance in the hinge against further opening movement of the door in a predetermined angle of the door opening.
