ABSTRACT:
The hinge comprises an elastic return mechanism (8, 12, 13) for the side (5) towards its normal open position, said mechanism being positioned concentrically in the side (5).
The elastic return mechanism comprises an envelope (8) which abuts against a spring (12) positioned inside an external casing (13) which is able to slide on the envelope (8).
Beyond the normal open position, this casing moves back while sliding around the envelope (8) and causes compression of the spring (12).
The envelope (8) which is integrated with the side (5) directly abuts against the spring (12), or a stopping member (16) is interposed between the envelope (8) and the spring (12), this member (16) being integrated with the side (5).
