<p>A resilient return articulation system (1) interposed between two elements, particularly between a spectacle arm (3) constituting a movable element (2) and a post constituting a fixed element (4), from a frame of its optical or solar surface (5) or attached directly to said surface, characterised in that said articulation (1) is composed of at least one flexible blade (6), initially bent, and which can be deformed elastically. Said flexible blade is an extension of the mobile element (2) and is housed in a casing (7) rigidly attached to the other fixed element (4), said casing (7) defining a parallelepipedic internal volume (8), the cross-section thereof being suitable for enabling the rotation of said blade by exerting an action on the extension element (2), crossing a central side opening (9) of the casing (7), allowing for at least two angular 90° positions.</p> |
