A tracking base assembly for an aircraft seat includes base rails mounted to floor tracks in an aircraft cabin by floor track fittings in fixed positions, the base rails connected by a tracking member for providing longitudinal tracking while minimizing added height. The base rails include tracking slots extending longitudinally, and the tracking member includes tracking elements translatable forward and backward along the tracking slots, allowing an aircraft seat mounted to the tracking member to translate forward from a retracted configuration into an extended or berthing configuration (and backward to the retracted configuration). The tracking member includes a locking mechanism for locking the tracking member and seat in intermediate positions within the tracking slots. The tracking slots may be oriented slightly downward from the horizontal to allow for gravity-assisted tracking or to counteract the nose-up flight angles associated with cruising altitude, providing for easier seat tracking.

A device for securing passenger seat frame structures (e.g., seat spreaders, legs) to a lateral crossbeam includes a wedged clamping device insertable into a pocket directly adjacent to a passage allowing the crossbeam to pass through the seat frame structure. The wedged clamping device has an upper face providing a locking taper angle and a lower arcuate face opposite the upper face and in contact with the crossbeam. When inserted into the pocket, the wedged clamping device provides a clamping force securing the seat frame structure to the crossbeam without driving a bolt through, deforming, or otherwise compromising the integrity of the crossbeam. The wedged clamping device accepts a tuning bolt through a lateral face; tightening the tuning bolt can more precisely control the amount of clamping force provided on the crossbeam.

The invention relates to a seat unit, in particular for an aircraft cabin, comprising: a seat provided with seat cushion and backrest kinematics, and a seat-base structure on which the seat is mounted, the seat-base structure comprising a frame with a tubular structure comprising: a first lower tube and a second lower tube, the first lower tube and the second lower tube each carrying at least one bolt intended to be fastened to rails, and two fastening feet for fastening the seat cushion and backrest kinematics, a fastening foot being formed by a tube connected by one of its ends to the first lower tube of the frame and by its other end to the second lower tube of the frame.

An object of the present invention is to provide a seat unit structure, a seat unit, and an attachment method thereof in which component reinstallation does not arise when the seat unit is attached in an aircraft. One representative seat unit structure according to the present invention relates to a seat unit structure configured to support a seat, wherein the structure has a lower structure having a monocoque structure and defines an outermost shell in at least one direction of the seat unit. That is, the member mounted in the one direction of the seat unit can be stored inside the outermost shell of the structure. In addition, the one direction is the width direction of the airframe.

Described are passenger seat bottom assemblies that include a layered seat bottom assembly formed of a first face sheet, a lightweight core layer, and a second face sheet bonded together, preferably in a flat or substantially flat arrangement. The core layer can be a honeycomb structure, e.g. a metal or aluminum honeycomb, or a foam, that confers a high strength and stiffness to the seat bottom assembly with minimal forming and minimal weight.

The invention relates to an aircraft passenger seat comprising a support framework, the support framework being designed to be fastened to a floor in an aircraft passenger cabin, wherein the support framework has a seat divider and bars running transversely to the seating direction, the seat divider being supported by the bars. A housing comprises a structural component and the housing at least partly surrounds a backrest. According to the invention, the seat divider is connected to the structural component via a connecting device, the connecting device being designed as a plug-in connection.

A seat unit for an aircraft that can be directly fixed at three points to a seat track provided on the floor of the aircraft. One representative seat unit and attachment method thereof relates to a seat unit comprising a lower structure of the seat unit and three fixtures configured to attach the lower structure directly to a pair of seat tracks of a mobile body, wherein the three fixtures include a lateral position adjustment member configured to laterally adjust a fitting position with the pair of seat tracks, a first fixture is fixed to one of the pair of seat tracks, a second fixture is fixed to one of the pair of seat tracks at a point separated from the first fixture, and a third fixture is fixed to another one of the pair of seat tracks at a corresponding portion between the first fixture and the second fixture.

A seat assembly is configured to be positioned within an interior cabin of a vehicle. The seat assembly includes a seat support structure that is configured to connect to a floor structure within the interior cabin of the vehicle. The seat support structure includes a seat base and a front end opposite from a rear end. Arm rests are pivotally coupled to the seat support structure. A seat back is pivotally coupled to the seat support structure proximate to pivotal coupling of the arm rests to the seat support structure. In at least one other embodiment, a seat back coupling upwardly and rearwardly extends from a middle portion of the rear cross beam. A seat back includes a narrowed mounting portion that pivotally couples to the seat back coupling without interfering with knee space formed in a back side of the seat back.

A passenger seat having a frame is proposed, wherein the frame is intended for securing to a floor of a passenger cabin, wherein the frame comprises a seat divider and beams that run transverse to the seat direction, wherein the seat divider is held by the beams, wherein a housing is disposed on the seat divider, wherein the housing at least partly surrounds a backrest. According to the invention, a structure component is disposed on the seat divider, with an attachment unit for a safety belt for a passenger disposed on the structure component.

An interior layout of an aircraft cabin extends along a longitudinal axis on a floor and comprises a table having at least one leg, at least one base for each leg and at least one flat tabletop. Each base is intended to be fixed to the floor, each leg is mounted on a base, and each flat tabletop is mounted on at least one leg. The table defines at least one main aisle accessible to a passenger of the aircraft. The main aisle extends in the longitudinal axis along a longitudinal edge of the flat tabletop. The interior layout comprises at least one seat arranged opposite the table. The seat has a seating direction oriented transversely to the longitudinal axis.
