Abstract:
Anti-vibration mount intended to be interposed between two rigid elements to damp vibrations between said two elements, essentially along a central axis, said mount comprising:an elastomer body substantially centred on the central axis; a rigid base which is fixed to the elastomer body and which comprises an outer annular periphery surrounding said elastomer body, said periphery extending substantially in a plane perpendicular to the central axis, said annular periphery surrounding the central axis and including at least a first portion which is oriented racially outwardly relative to said central axis; a rigid head fixed to the elastomer body and offset from the base along the central axis; a first mount part extending on a section of the mount height, axially from the head to said periphery; a second mount part opposite said head relative to said periphery; and at least a first non-extensible cable forming a loop which is fixed to the base and to the head to limit the distance between said base and said head, the first cable surrounding the anti-vibration mount on only the first mount part so that the second mount part can be left completely free, said first cable comprising: a first part which is held to the head by winding around said head and which extends towards the base, starting from the said head; and a second part which runs along at least said first portion of the periphery of the base, said second part of the cable bearing radially inwardly on said first portion of the periphery of the base, said second part complementing the first part of the first cable to form said loop formed by the first able, the second part of the first cable winding around at leas a first return element forming part of the periphery of the base, level with two joints between said second part and the first part of the cable, the first cable being so restrained by the first return element that said first return element prevents any displacement of the second part of the first cable towards the head.
