ABSTRACT:
The hinge device according to the present invention is constituted by a first element provided with a guiding surface for the rotation about a predetermined axis of a second element which is provided with a surface movable about the axis and thus suitable for cooperating with the guiding surface.
According to an essential feature of the invention, at least the second element is further provided with a series of interconnected grooves which form respective housings for a resilient element which is positioned in the grooves; the resilient element, which is generally constituted by a leaf spring, and a portion of which is clamped on the first element or is integral therewith, forms the connecting member between the first and second elements, allowing to the latter a movement along the guiding surface, and imparting to both elements a resilient restoring force towards predetermined positions.
