<p>Latch system comprising two elements (10, 11) connected mechanically to one another so as to be incapable of moving apart, and a cam (1) mounted rotatably on the first of said elements and having a contact surface (3) pressing against a bearing face (5) carried by the second of said elements. <??>According to the invention, said contact surface (3) of said cam has at least approximately a profile in the form of a logarithmic spiral, whilst said bearing face (5) is plane and said cam can rotate about a hub (22), on the axis of which is located the origin of said logarithmic spiral, said hub being mounted rotatably on said first element about an eccentric axis of rotation (20') opposite said contact surface of said cam in relation to the axis of said hub. Elastic means are provided for rotating said cam in a first direction (f1) such that said contact surface shifts toward said bearing face. <IMAGE> </p> |
