Abstract
A vibration filter mechanism between a fuselage and a piece of equipment of the aircraft. The filter mechanism comprises a pair of filter members, each secured with a first structure that is to be connected to the fuselage and with a second structure of the piece of equipment. Each filter member is secured with the first structure via a first pivot type connection having one degree of freedom to move in rotation and with the second structure via a second pivot type connection having one degree of freedom to move in rotation. The filter mechanism includes resilient return means for deforming during relative movement in rotation between at least one of the filter members and the first structure. The resilient return means presents a predetermined stiffness suitable for generating a return force opposing the relative movement in rotation between at least one of the filter members and the first structure.
