Patent ID: 6857674

Claim:
Articulated device ( 10 ) that will form part of a system ( 100 ) for filtering vibrational movements from a vehicle floor ( 12 ) and transmitted to a passenger support ( 19 ), characterised in that it is installed between said floor ( 12 ) and said support ( 19 ) in that it comprises the following five elements: two mounts ( 20 ) fixed to the vehicle floor ( 12 ), one mobile central part ( 22 ) articulated to the support ( 19 ), two connecting rods ( 24 ), each articulated to one of the mounts ( 20 ) and to the central part ( 22 ), and in that these five elements ( 20 , 22 , 24 ) are articulated to each other and to the support ( 19 ) by rotation joints, the rotations operating about five rotation axes ( 34 , 36 , 32 ) parallel to each other, such that the rotation axis ( 32 ) between the mobile central part ( 22 ) and the support ( 19 ) moves in translation along a curved trajectory ( 160 ) contained in a (Y, Z) plane perpendicular to the plane of the floor ( 12 ).
