    摘要: The invention provides a vibration filter mechanism for aircraft equipment. A weighted lever arm (5) is hinged via bearings (22, 23) associated respectively with a first structure connected to a fuselage and with a second structure connected to the equipment (12). Deformable means (7) oppose pivoting movement of the lever arm. The lever arm (5) is arranged as a one-piece fork that comprises a pair of branches (19, 20) that are interconnected by a crossbar (21) and that are hinged to the bearings (22, 23) about spaced-apart parallel pivot axes (A1, A2). The fork carries a torsion shaft (24) that extends between the branches (19, 20) at their free ends (9), the torsion shaft (24) constituting the weight weighting the lever arm (5) and the deformable means (7) of the mechanism.
