A hinge for automobile doors so as to provide for gull-wing operation comprising fastening elements provided with fixed pivot pins and with sliding guides, which can be housed respectively in the thickness of the door and in a corresponding roof header; linkages for connecting the fastening elements with their first extremity, hinged on the fixed pivot pin of one of the fastening elements and with a second extremity including a shoe engaged in the sliding guide of the other fastening element; and a joint interposed at the extremities of the linkages which pivotally connects the linkages to each other allowing their relative angular mobility. The fastening elements further comprise a control means in cooperative engagement with the sliding guide and shoe for adjustably controlling the maximum range of rotation of the hinge.
