  "abstract": "A resilient suspension device for the exhaust pipe of any vehicle having an internal combustion engine, the device comprising a resilient body provided with fastener means for fastening both to the structure of the vehicle and to said exhaust pipe. The device is characterized in that it includes at least one transverse bar 8 carrying a counter-oscillating mass M, the end 9 of said bar remote from said mass M being included in a zone 16 of said body which is subject to vibration, and said bar 8 being held in a location situated between said zone 16 and said mass M by a relatively fixed portion 10 of said body, forming a pivot.",
  "claims": [
    "1. A resilient suspension device for the exhaust pipe of a vehicle having an internal combustion engine, the device comprising a resilient body provided with fastener means for fastening both to the structure of the vehicle and to said exhaust pipe, the device being characterized in that it includes at least two transverse rigid bars (8) each carrying a counter-oscillating mass (M), the ends (9) of said bars remote from said mass (M) being included in zones (16) of said body which are subject to vibration, and said bars (8) being held in a location situated between said respective zones (16) and said masses (M) by portions (10) of said body, forming pivots.",
    "2. A device according to claim 1, characterized in that said resilient body (11) has two portions (10), each of which constitutes said portion forming a pivot for said respective transverse rigid bars (8) passing therethrough, wherein each bar includes a free end carrying a counter-oscillating mass (M) and wherein each bar includes an end (9) opposite to said free end received in a middle zone (16) of the body (11) that is subject to the vibration.",
    "3. A device according to claim 1, characterized in that said resilient body (11') is generally ring-shaped, having two reentrant arms (15), each incorporating a rigid bar (8) carrying a counter-oscillating mass (M) at its inside end, with the opposite end (9) of the corresponding bar being included in a zone that is subject to the vibration.",
    "4. A device according to claim 1, characterized in that said bar (8) and said mass (M) are coated in rubber."
