Claim 5

Support. according to CLAIM 3, characterized by the fact of comprising an actuator, constituted by an electric motor (22) that controls the rotation of the said rotatable disc.

Claim 6

Support, according to CLAIM 1 or 2, characterized by the fact of comprising a first and a second chamber (16, 17) filled with said liquid, and made between said elastically deformable element and a first bell-shaped element (9) fixed to said frame and between the bell-shaped element and a deformable membrane (13), a second bell-shaped element (11) rotatable with respect to the first, on the bottom walls of said bell-shaped elements, there being made a first and a second groove (12) and a first and a second hole (14) apt for originating a conduit (13) that puts the said chambers into communication and, on the lateral walls of said bell-­shaped elements there being made a first and a second series of perforations (15), said second bell-shaped element being rotatable with respect to the first element from a first angular configuration wherein the perforations of the two series are not overlapped and hence, said chambers are in communication solely through said conduit, and a second configuration wherein said perforations are overlapped and hence, said chambers are in communication with one another through the perforations themselves.

Claim 7

Claim 8

Support, according to CLAIM 1, characterized by the fact of comprising a chamber (32) filled with said liquid and defined between said elastically deformable element (7) and said frame (6), inside of said chamber there being disposed a disc (34) connected to said deformable element through coupling means that comprise a connecting-rod (35) mobile in the direction of its axis, and provided with a head (36) apt for blocking said disc (34), said disc being axially mobile on said connecting-rod between said head and an abutment made on said elastically deformable element, the axial position of said connecting-rod, with respect to said abutment, being controlled through the means of a special actuator.

Claim 9

Support, according to CLAIM 7, characterized by the fact that said connecting-rod (35) is provided with an anchor (37), and that said actuator is comprised by an element (38) apt for attracting said anchor.

Claim 10

Support, according to CLAIM 7, characterized by the fact that said connecting-rod is rotatable around its own axis and that it presents a helicoidal groove (39) coupled with a plug (4) made solidal with said deformable element, said actuator being constituted by an electric motor apt for controlling the rotation of said connecting-rod in such a way as to cause its axial shifting.
