The door hinge is composed of two parts (1,2) pivoting on an axis (X-X). Each part is constituted from a plate stack. The parts consist of plates (3) forming pivots and plates (4) forming tenons (8) which pivot in a drilling (7) in a pivot plate. Plates (5,6) forming struts are located between the tenons and pivots. The thickness of each strut is equal to the thickness of a plate forming a tenon. A piece (13) holds apart the tenon and pivot plates at the top of the hinge axis. All the tenon plates are assembled with the strut plates (6) to constitute one part of the hinge when all the pivot plates s are assembled with the strut plates (5) to constitute the other hinge part.
