An orientation assembly includes a platform and a locking assembly engageable with the platform and positionable in a first state in which the platform is permitted to rotate about a lateral axis and inhibited from rotating about a longitudinal axis perpendicular to the lateral axis, and a second state in which the platform is permitted to rotate about the longitudinal axis and inhibited from rotating about the lateral axis.

A latch assembly may comprise a keeper and a lever. The keeper may include a keeper channel defined at least partially by a first channel surface and a second channel surface. The lever may be configured to rotate relative to the keeper and between an engaged state and a released state. The lever may comprise a shaft and a lever protrusion extending from the shaft. The lever protrusion may be defined at least partially by a proximal surface and a distal surface. The keeper channel may be configured to receive the lever protrusion. In the engaged state, the proximal surface of the lever may contact the second channel surface of the keeper and the first channel surface of the keeper may be spaced apart from the lever protrusion.

Described are tray tables having a shroud and a core assembly. The shroud may form an outer surface of the tray table. The core assembly may be within the shroud and may include a top sheet, a bottom sheet, and a honeycomb core. The honeycomb core may be between the top sheet and the bottom sheet. The honeycomb core may define a plurality of cells.

A movable close-out shroud suitably configured to substantially cover, partially block, or otherwise close out an articulating opening to a cavity, void, etc., of a first part, such as a passenger seat section. The close-out shroud is configured to move between a stored position and a close-out position.

Passenger seating positioned proximate to an aircraft interior structure includes at least one seat base assembly and at least one seatback assembly. The at least one seat base assembly includes a seat pan, and is attached to a floor of an aircraft cabin. The at least one seatback assembly includes a support structure and a seatback couplable to the support structure. The seatback includes a surface contoured to a passenger profile. The support structure is couplable to the aircraft interior structure attached to the floor of the aircraft cabin via at least one quick-release mounting assembly, with components of the at least one quick-release mounting assembly being coupled to the support structure and the aircraft interior structure. The at least one seatback assembly is not directly coupled to the at least one seat base assembly.

In a passenger seating arrangement in an aircraft cabin, the passenger seating arrangement has exactly two rows of seat units and exactly one aisle. A first row of seat units and a second row of seat units are separated by the aisle. The rows of seat units and the aisle all extend in a longitudinal direction parallel to a longitudinal axis of the aircraft cabin. Each seat unit includes a seat, an upper shell and a lower shell, the lower shell forming a footwell. The seats are arranged in parallel to each other in a seating direction. An upper shell of a first seat unit and a lower shell of a second seat unit, which, viewed in the longitudinal direction, is arranged behind the first seat unit, partially overlap in a vertical direction.

An orientation assembly includes a platform and a locking assembly engageable with the platform and positionable in a first state in which the platform is permitted to rotate about a lateral axis and inhibited from rotating about a longitudinal axis perpendicular to the lateral axis, and a second state in which the platform is permitted to rotate about the longitudinal axis and inhibited from rotating about the lateral axis.

An adjustable swiveling passenger seat assembly is disclosed. The adjustable swiveling passenger seat assembly includes a set of base rails coupled to a floor. The adjustable swiveling passenger seat assembly further includes a plurality of pitch clevises coupled on a top surface of each of the set of base rails. The adjustable swiveling passenger seat assembly includes a swivel outer plate aligned in parallel relative to the floor. The swivel outer plate of the adjustable swiveling passenger seat assembly further includes a plurality of slots located on corners of the swivel outer plate and a plurality of spacers disposed within the plurality of slots.

An airplane seat device includes at least one functional unit that is configured at least for a locking, a controlling and/or a movement of at least one airplane seat element, wherein the functional unit includes at least one actuatable shape-memory element.
