<p>The invention concerns an elastic hinge for specticles frame comprising two fixed (5) and mobile (7) hinge elements, articulated about an axis of rotation (R) by a pivoting head (7A) of one (7) of the elements inserted in a pivoting head (5A) of the other element (5) and by a link (9) housed in succession in an inner passage (5D, 7D) of the two elements emerging into the pivoting heads. The invention is characterized in that each pivoting head (5A, 7A) has at the opening of the passage (5D, 7D) a stop member (B1, B2) on the outer side of the frame forming by the matching shape of one (B1) with the other (B2) a pivoting interface about a second axis of rotation (R'), the link (9) being arranged between the two axes of rotation (R, R') when the bow is in a normal opening position. The hinge has two stable closing and opening positions as well as an additional unstable opening position.</p> |
