Claim 3

Device as in claim 1, characterized by the fact that the cavities of said body have a substantially flat shape.

Claim 4

Device as in claim 1, characterized by the fact that said body is constituted by a plurality of cushioning pads (5) of elastomeric material comprising cavities, said pads being overlapped among them, and each pad being delimited between two armours s (6), (7).

Claim 5

Device as in claim 1, characterized by the fact of comprising in combination with said body of elastomeric material an elastic element (9), said element being arranged in compression state between a suitable support (10) and an oscillating system (M), said body (1) of elastomeric material being associated at one extremity to said support (10) and having the opposite extremity at a distance from said oscillating system.

Claim 6

Device as in claim 4, characterized by the fact that said elastic element is a low hysteresis elastomeric material.

Claim 7

Device as in claim 4, characterized by the fact that said elastic element is natural rubber.

Claim 8
