The spectacle frame hinge (30), comprising first (10) and second (20) components and a pivot pin (13), has at least one positioning stud (14) on one of the two components, interacting with an elastic arm (26) on the other that has at least one positioning zone (C1, C2). The stud is designed to co-operate with the positioning zones when the hinge is in certain predetermined positions to give stability while requiring only a small effort to move it from one position to another. The elastic arm has a free end and recesses or projections to form the positioning zones. |
