Abstract: A hinge is made of two elements articulated to one another. One element constitutes at least one fork, supporting the hinge pin, and the other element constitutes at least one hub fitted on the hinge pin supported by the fork. Each bearing of the fork and each hub is connected by a tenon to a leaf of the hinge. The hubs and bearings of the two elements are accommodated in a housing of elastic material such as a metal or other appropriate material, such as a plastic or the like. The housing is rotationally connected with the bearings of each fork, with a longitudinal slot being provided in the housing, arranged parallel to the hinge pin. The slot is designed to allow tenons of both elements of the hinge to pass. The width of the slot is determined, at least by correspondence of the tenon of each hub, as a function of the maximum desired opening angle.
