Device and system for filtering vibrational movements of a passenger support, and passenger support equipped with such a system

Abstract

The articulated device (10) that is intended for filtering vibrational movements from a vehicle floor (12) and transmitted to a passenger support (19), is installed between said floor (12) and said support (19), and comprises 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 the central part (22). 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 (32, 34, 36) that are parallel to each other. The system (100) for filtering vibrational movements transmitted to a passenger support (19) comprises at least three filtering devices (10), such that the support (19) moves in translation along a plane curved trajectory. To be used for an aircraft seat.
