A snap-acting hinge (1) with damped closure and opening angle of more than 90°, comprising a first articulated quadrilateral (2) and a second articulated quadrilateral (3), which have a first lever and a second lever (4, 5) in common and are provided with respective base elements constituted by a plate (6) for coupling to a fixed element (100) and by a plate (8) for fixing to a movable element (101), the hinge (1) being movable between an open configuration and a closed configuration, in which the fixing plate (8) has different arrangements with respect to the coupling plate (6) which are angularly spaced apart by an angle of more than 90°.
The hinge further comprises first elastic means (12) for holding the open configuration which are associated with the first quadrilateral (2), second elastic means (13) for holding the closed configuration which are associated with the second quadrilateral (3) and damping means (14) that act in the transition from the open configuration to the closed configuration and which are interposed between the first lever (4) and the fixing plate (8).
