Patent Description:
A typical seat assembly within an internal cabin of an aircraft includes a tray table on a rear portion. The tray table is configured to be selectively stowed and deployed by a passenger seated on another seat assembly behind the seat assembly. Certain seat assemblies also include a monitor above the tray table, as well as a literature pocket below the tray table.

Reading lights for passengers are typically located above a seat assembly. For example, a reading light is often disposed within a passenger service unit (PSU) above the seat assembly. Due to the location of the reading light above the seat assembly and proximate to a stowage bin, a passenger generally extends a full length of an arm to reach and engage a switch for the reading light. However, certain smaller individuals may have difficulty reaching the switch, particularly when seated.

Additionally, because the reading light is located above the seat assembly, the light element typically requires a voltage and brightness sufficient to illuminate an area that allows an individual to comfortably and easily read. As can be appreciated, the farther away the reading light, the higher the voltage and brightness that are typically required.

Also, the elevated location of the reading light away from the passenger increases the amount of wiring, such as within the PSU, thereby increasing weight, cost, and complexity.

<CIT>, in accordance with its abstract, states a system for sanitizing a tray table including a sanitation assembly operatively coupled to the tray table. The sanitation assembly includes an ultraviolet (UV) light source configured to emit UV light, and a sanitation control unit operatively coupled to the UV light source. The sanitation control unit operates the UV light source to emit the UV light onto the tray table when the tray table is secured in an upright position, and prevents the UV light source from emitting the UV light when the tray table is not secured in the upright position.

<CIT>, in accordance with its abstract, states a seat back illumination module having a housing defined by an interior and a partially open front face. A switch member with a first position and a second position at least partially protrudes from the front face of the housing and is engaged thereto. An illumination assembly is defined by an output end and has an illumination source. At least a part of the illumination assembly is mounted to the switch member, and the output end is proximal to a section of the switch member that protrudes from the front face of the housing. An electrical switch is connected to the illumination source and operated by movement of the switch member between the first position and the second position to selectively power the illumination source.

A need exists for an efficient and effective system and method for illuminating a volume of space within an internal cabin. Further, a need exists for a lighting system within an internal cabin that is easily reachable by passengers. Additionally, a need exists for a lighting system within an internal cabin that draws a reduced amount of power.

A seat assembly for an internal cabin of a vehicle is provided, as defined in claim <NUM>. In at least one example, the lighting system may be secured to an aft portion of the backrest. The seat assembly can also include a tray table configured to move between a stowed position and a deployed position.

The lighting system includes a housing. In at least one example, the lighting system may include one or more lamps within the housing, and a cover secured to the housing. The one or more lamps may be behind the cover. As a further example, the one or more lamps may include a reading lamp configured to emit reading light. As a further example, the one or more lamps may also include an ultraviolet (UV) lamp configured to emit UV light.

In at least one example, the seat assembly may also include a control switch coupled to the backrest. The control switch may be configured to be engaged to selectively activate and deactivate at least a portion of the lighting system.

A method of forming a seat assembly for an internal cabin of a vehicle is provided, as defined in claim <NUM>. In at least one example, said coupling may include securing the lighting system to an aft portion of the backrest. In at least one example, the method may also include coupling a control switch to the backrest, wherein the control switch may be configured to be engaged to selectively activate and deactivate at least a portion of the lighting system.

A vehicle including an internal cabin, and a seat assembly within the internal cabin is provided, as defined in claim <NUM>.

Examples of the present disclosure provide a lighting system for an internal cabin of a vehicle, such as a commercial aircraft. The lighting system is disposed within a backrest of a seat assembly in the front of a passenger, which provides an improved quality reading light experience for the passenger, and places the accessibility of the light controls easily within reach of an arm of an individual. In comparison, the control switch for the lighting system can be placed within a short distance from the passenger (such as inches away on the seat backrest). In at least one example, the lighting system also includes an ultraviolet (UV) light element (such as one or more UV light bulbs) that are configured to provide a germicidal lamp, which can be used to sanitize a surface of a tray table.

As described herein, examples of the present disclosure dispose a reading light and switch configured to control the reading light within easy reach of a passenger (in contrast to known reading lights that are above a seat assembly and a relatively far distance away from the passenger). Accordingly, the passenger has immediate and full control of the reading lighting within a personal space. Also, the passenger benefits from direct lighting directed onto personal space, which provides higher quality and more direct lighting to the passenger.

As noted, the lighting system can also include a UV light element that is configured to sanitize one or more surfaces, such as of a tray table, armrests of a seat assembly, and/or the like. The UV light element can be in communication with a control unit that is configured to control operation thereof. The UV light element can be activated by attendants or other crew after passengers have left the internal cabin.

There is provided a seat assembly having a seatback and a lighting system coupled to the seatback. In at least one example, the lighting system includes a removable housing supporting a reading lamp including one or more light elements (such as one or more bulbs, light emitting diodes, and/or the like configured to emit white light), and a UV lamp including one or more light elements (such as one or more UV light bulbs, light emitting diodes, and/or the like). The reading lamp is operable by a passenger to direct light toward the passenger and/or a tray table. The UV lamp is operable by the crew for disinfection of the air and surface around the passenger seating area. Disposing the UV lamp closer to the passenger seating area can reduce the power supply requirements (as compared to the UV lamp being overhead or somewhere else). In at least one example, the removable housing can include apertures formed to direct the reading light and UV light to desired areas, such as the tray table or arm rests when deployed. In at least one example, either or both lights can turn on automatically when the tray table is deployed.
