The invention relates to a seat ( ) for an aircraft comprising a squab ( ), a backrest ( ), a leg rest ( ), a support structure ( ) for the squab ( ) and the backrest ( ), and a fixed rear separation shell ( ). The support structure ( ) or the squab ( ) moveable in translation in a direction substantially perpendicular to the backrest ( ) in the vertical position. The seat ( ) is situated in a space lying between a fixed front separation shell ( ) and a fixed rear separation shell ( ). The movements of each of the components ( ) of the seat are independent of each other and the fixed separation shells ( ).

Multiple position seat for plane

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. The transmission element is coupled to the tray to urge the tray to rotate with respect to the seat back.

Dismountable articulation device, seat structure, seat and vehicle equipped with this device

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. The linkages support the seat proper and couple movement of the back and of the seat proper in such a manner that when the back passes from its sitting position to its sleeping position it causes at least an upward movement of the seat proper and that, conversely, when the back moves from its sleeping position to its upright sitting position, it causes at least an opposite downward movement of the seat proper.

Device for adapting the position of the seat proper for a seat having a

The device concerns a driving gear for Convertible public transportation seats with variable spacing (2a, 2b, 2c) along a dimensional axis (3), the seats (2a, 2b, 2c) being mounted on a structure (4) with several adjacent seats (2a, 2b, 2c), with each of them separated from the next by a space between frames (5) and sliding on the structure (4) along the dimensional axis (3). A driving gear comprises a worm (6) whose axis (7) is parallel to the dimensional axis (3) and which is coupled with at least one nut (8) attached to the seat (2a, 2b, 2c) to be driven, in such a way that when the worm (6) is forced to rotate in one direction the seat (2a, 2b, 2c) is driven from one extreme position to another and when the worm (6) is forced to rotate in the other direction the seat (2a, 2b, 2c) is driven to move in the opposite direction.

A convertible seat with variable dimensions for public transportation, comprises back lengthening elements, association and positioning device to fit the lengthening elements on either side of the back opposite to the side-edges, and to position the lengthening elements between a retracted position corresponding to a position of minimum seat dimensions along a dimensional axis and a stretched position corresponding to a position of maximum seat dimensions along the dimensional axis.

Convertible seats with variable dimensions for means of public

A structure comprising a plurality of adjacent seats for a public passenger vehicle, in particular an airliner, the structure being convertible and of variable size along a sliding axis (100), and comprising:

The invention relates to a passenger seat for a public transport vehicle, in particular an aircraft, the seat including at least one armrest 1 and at least one individual video display 2 associated with the armrest 1, said seat being characterized in that the video display 2 is retractably mounted via a slot 3 provided in a top wall 4 of the front portion 5 of the armrest 1.

Passenger seat for a public transport vehicle, the seat including a

A hinge device for seats of public transport vehicles--especially airliners--adapted to allow the seat squab frame (2) to tilt relative to the seat cushion frame (3) about a tilt axis (4). The seat squab frame (2) is generally U-shaped with the web forming the top of the seat squab frame (2) and the sides forming the lateral edges (6) of the seat squab frame (2). The seat cushion frame (3) has a rear part (7) including two rear free ends (8). The tilt axis is horizontal and passes through the rear free ends (8) of the seat cushion frame (3) and the free ends (9) of the lateral edges (6) of the seat squab frame (2). The hinge device includes at least one free end (9) of the seat squab frame (2) a journal member (10) rigidly coupled with and fastened to the seat squab frame (2), projecting out of the seat squab frame (2) and aligned with the tilt axis; at the rear free end (8) facing the journal member (10) a journal support (11) rigidly coupled with and fastened to the rear part (7) of the seat cushion frame (3), projecting into the seat cushion frame (3) and aligned with the tilt axis; the journal member (10) and the journal support (11) having respective coupling structure (12, 13) providing a removable and secure coupling and enabling rotation of the journal member (10) about the tilt axis, the journal member (10) extending axially over a substantial part of the tilt axis segment between the free end (9) of the seat squab frame (2) and the rear free end (8) of the seat cushion frame (3).

Hinge device for public transport vehicle seats and seat structure

The invention relates to an underframe for a passenger aircraft seat, the underframe including a triangular base defining a front anchor point and a rear anchor point, and a raised intermediate vertex; and a leg associated via its top end with the structure of the seat and via its bottom end with the triangular base. In accordance with the invention, the leg is associated rigidly with the base by rigid association means which, during normal use of the seat, hold the leg positively relative to the base, in particular so as to prevent any forward or backward pivoting of the leg.

Underframe for a passenger aircraft seat, and a seat including such an

An underframe for a passenger aircraft seat, the underframe including at least one element forming a front leg and at least one element forming a rear leg, and energy absorption structure that is active when a moving element of the seat moves relative to another element of the seat or of the floor of the aircraft cabin, under the effect of the seat being subjected to deceleration above a predetermined value. The energy absorption structure includes an energy absorption device including a male part that penetrates by force and with plastic deformation into an aperture in a female part. Either the female part or the male part is attached on and directly associated with the moving element, and the other part, i.e. the male part or the female part, is attached on and directly associated with the other element.

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.

Control devices for use with a sheathed wire or cable

A device for actuating a sheathed control cable comprises a push button wh is movable to apply a tension to the cable. An inclined surface rigid with the push button engages, via a ball, a traction member anchored to the cable. When the button is depressed the inclined surface displaces the traction member via the ball whereby the cable is tensioned. The ball rolls along the inclined surface during this movement whereby such movement occurs substantially without friction.
