Abstract: A displacement mechanism of a tray table mounted on an armrest of a seat, said mechanism allowing to correct the lie angle of said tray table keeping it substantially horizontal, said seat being provided with a displacement mechanism, said displacement mechanism of a tray table providing a lever, hinged in the front-upper zone of the armrest where said tray table is arranged, said lever allowing said tray table to rotate in a longitudinal vertical plane, a hinge, arranged at the end of said lever opposite to the one hinged to the armrest, allowing said tray table to rotate according to an arc of a circle lying in a substantially vertical transversal plane, coupling means, provided under said tray table, and downward facing, when said tray table is in a use position, in proximity of said hinge, said lever being hinged on the armrest.

Abstract: The present invention relates to a displacement system of at least a side of a seat, in particular airplane seat, said seat comprising at least a support structure and a structure movable with respect to said support structure and that can pass from a seating configuration to an extended or bed configuration or to a straddle configuration, and vice versa, said displacement system having pushing mans connected with said movable structure of said seat and in that it is realised in such a way that, when said movable structure of said seat is in the straddle configuration, said pushing means pass from an engaged position, wherein they are engaged with said side acting on the same so as to follow the configuration and/or the movement of said seat.
