A toilet that comprises a bowl, a lid, and a seat, wherein the seat is attached to the bowl by a first hinge, while the lid is attached to the seat by a second hinge, this second hinge presenting the possibility of turning with respect to the first hinge. The possibility of automatically tilting the seat towards the lid when the lid is raised and the seat separated from the lid is achieved by arranging the second hinge in a position that is set back with respect to the first hinge, and with the lid producing a torque with respect to the first hinge, that is greater than the opposing torque of the seat with respect to the first hinge, causing the seat to tilt towards the lid automatically.

The invention therefore relates to a cushioned coupling hinge 1 suitable to rotatably couple the seat-ring 71 and the lid 72 of a toilet seat to a toilet 70. The hinge 1 comprises a cushioning mechanism suitable to cushion the falling movement of the mobile component during rotation around the axis of rotation X; a mobile portion 20 integrally constrainable to the seat-ring or lid in rotation; a fixed portion 30 integrally constrainable with the toilet 70. Advantageously, both the maintenance in position of the hinge along the axis of rotation and the actuation of the cushioning mechanism is obtained by means of a single engagement element 4 inserted at right angles to the axis of rotation simultaneously through the seat-ring/lid to be cushioned and the mobile portion 20.
