  • Patent number: 6688691
    Abstract: The invention relates to a seat (1) for an aircraft comprising a squab (2), a backrest (3), a leg rest (4), a support structure (5) for the squab (2) and the backrest (3), and a fixed rear separation shell (13). The support structure (5) or the squab (2) moveable in translation in a direction substantially perpendicular to the backrest (3) in the vertical position. The seat (1) is situated in a space lying between a fixed front separation shell (12) and a fixed rear separation shell (13). The movements of each of the components (2, 3, 4) of the seat are independent of each other and the fixed separation shells (12, 13).

  • Patent number: 6260917
    Abstract: Apparatus for a swiveling a tray mounted in the back of an aircraft seat. The apparatus has a tube oriented transverse to the seat back around which the tray swivels. A tray is pivotably attached to the tube. A pair of bushes protrude outward from each end os the tube. Each bush ends in a generally mushroom shaped protrusion which is set off by an adjacent undercut defining a stressing and guiding zone. An elastic spring contained within a housing is mounted on the aircraft. The mounted spring has upward directed Y-shaped openings sized to receive and engage the protrusion at the backlash elimination zone and engage the protrusions and the tube. This spring grips and hold the protrusions which secures the tube. This arrangement permits the tube and its attached tray to be quickly and easily attached or removed from the seat. A transmission element in the form of an extending arm is also pivotably attached to the tube.

  • Patent number: 5788183
    Abstract: A device for a seat, in particular an aircraft seat, the seat having a back that pivots between an upright sitting position and a folded-down sleeping position, the device serving to cause the seat proper of the seat to take up an appropriate position that matches that of the back. The device includes two support-and-drive assemblies designed to be disposed laterally on either side of the seat, each assembly having first and second hinged and deformable mechanical linkages designed to be associated mechanically firstly with the back to pivot relative thereto, and secondly with the seat proper in portions thereof that are respectively proximal and distal relative to the back.

  • Patent number: 4297912
    Abstract: A control device comprises an actuating push button slidable in a housing. A traction element, also slidable in the housing, is secured to the head of a flexible sheathed wire or cable. The traction element has an inclined surface which is engaged by a ball displaced by actuation of the push button whereby to cause displacement of the traction element and of the wire or cable connected thereto.
