Patent ID: 7472864

Claim:
A device for filtering vibration between two parts ( 2 and 3 ), the device being characterized in that it comprises: at least a first resilient plate ( 4 ) connected to said parts ( 2 and 3 ) at two respective fastening points ( 2 A and 3 A) defining an axis YY, said first plate ( 4 ) being locally deformable under the action of vibration transmitted by one of said two parts to the other part; and at least a first resonator ( 7 ) fitted with two laminated elastomer bearings ( 8 , 9 ) which firstly define an axis XX that is substantially perpendicular to the axis YY, these axes XX and YY intersecting at a point ( 10 ), and secondly receive respective fastener means ( 80 , 90 ) for fastening to said first resilient plate ( 4 ) in such a manner as to put said resonator ( 7 ) into oscillating pivoting motion during said local deformation of said first resilient plate ( 4 ) such that said resonator ( 7 ) generates an anti-vibratory inertia torsor that opposes said vibration and filters transmission thereof from one part to the other.
