An aircraft projection device includes a projector that displays an image by projecting the image onto a floor surface of a passage in an interior of an aircraft; and a controller that controls the projector to display the image onto the floor surface of the passage in the interior of the aircraft.

Certain aspects of the present disclosure provide a method that includes: collecting seat sensor data associated with a plurality of seats in a vehicle; selecting a first subset of data from the collected seat sensor data; providing the first subset of data to a fault detection model; receiving, from the fault detection model, one or more detected seat component faults; and generating, based on the one or more detected seat component faults, a seat condition map associated with the vehicle.

An adapter plate for an aircraft seat may include a body configured to be positioned exterior of an armrest of the aircraft seat within a space proximate to the aircraft seat. The body may include at least one coupler configured to attach to the aircraft seat. The body may include at least one mount point. The at least one mount point of the body may be configured to attach to at least one mount bracket of the removable auxiliary aircraft accessory. The auxiliary aircraft accessory may be positioned within the space proximate to the aircraft seat when coupled to the at least one mount point of the body via the at least one mount bracket.

A retention system for an aircraft seat dress cover defines a cable channel sewn around the periphery of a back portion. A cable in the cable channel is tightened to tighten the aircraft seat dress cover around an aircraft seat back. Adjustable buckles at terminals of the cable interlock and allow the cable to be tightened. A midpoint strap is disposed on opposing sides of the periphery to allow the aircraft seat dress cover to more fully conform to the structure of the aircraft seat.

A seat assembly within an internal cabin of a vehicle includes an electrical interface housing that contains a first portion of a cable that is configured to provide one or both of electrical power or electrical signals to one or more electrical components. A cable reel rotatably coupled to a body of the electrical interface housing. The cable reel is configured to rotate about an axis. The first portion of the cable includes an adjustable coil that is coiled around the cable reel. The cable reel is rotatable in a first direction to deploy the first portion of the cable outwardly from the electrical interface housing and a second direction to retract the first portion of the cable inwardly into the electrical interface housing.

A device having at least one communication unit arranged in a wall of the aircraft and at least one communication unit arranged in a seat of the aircraft, which are able to cooperate with one another in order to communicate data by means of visible light. The device also includes at least one inductive transmitter arranged in the wall and at least one inductive receiver arranged in the seat, which are able to cooperate with one another in order to transmit electric power by induction. Also a system with such a device and an aircraft with such a device or such a system.

A passenger service unit, a passenger seating area, and a vehicle having a passenger service unit are provided, wherein the passenger service unit comprises a carrier element that can be extended in a longitudinal direction and a covering. The covering covers at least a section of the carrier element. At least one electrical and/or electronic element is integrated in the covering.

A seat usage prevention device is disclosed. The seat usage prevention deice includes at least one device component being configured to interact with one or more seat components of a first seat. The device component is configured to prevent usage of at least one of a seat pan or seatback of the first seat. The device component further separates a second seat from at least a third seat, wherein the third seat is proximate to at least one of the first seat or the second seat. The seat usage prevention device may include a device component that further includes a cushion, a base, an amenity console, or a vertical separator, or combination thereof.

A method of assessing performance of a seat is provided. The method comprises identifying a number of critical seats for testing from a layout of passenger accommodation and building a computer simulation model, following a building block approach, for each identified critical seat. A number of loads are tested on each simulation model. Critical seats are selected for physical testing from simulation model test results according to a specified criteria assessment matrix.

An aircraft interior structure may include a primary monument, an auxiliary monument, and a passenger seating section. The primary monument may include one or more storage compartments and a primary panel configured to actuate between a primary panel stowed position and a primary panel deployed position. The auxiliary monument may be spaced a select distance from the primary monument across a floor area of an aircraft cabin, and may include an auxiliary panel configured to actuate between an auxiliary panel stowed position and an auxiliary panel deployed position. The passenger seating section may include a footwell at least partially within the primary monument and proximate to the one or more storage compartments. The footwell may correspond to an aircraft seat. The aircraft seat may be configured to form a bed surface with at least a portion being within the footwell when the aircraft seat is in a lie-flat position.
