Description

BACKGROUND

The present invention relates generally to aircraft interiors, and more particularly relates to a fully integrated commercial aircraft interior module including sidewall linings, decompression ventilation provisions, overhead stowage compartments, cabin air distribution ducting, personal service units (PSU) and ceilings, all configured to attach as an integrated interior module suitable for installation to existing aircraft structural supports, and suitable for retrofitting of commercial aircraft interiors.

Overhead stowage bins are currently generally shelf or fixed overhead stowage bins, pivot overhead stowage bins, or translating bins overhead stowage bins. The shelf or fixed bin is currently the most common design, having a door that typically opens outward and upward. Pivot and translating bin designs typically have a door that typically opens outward and downward at a controlled rate of opening, and provides good visibility during opening and closing.

Commercial aircraft interior sidewall linings, decompression ventilation provisions, overhead stowage compartments, cabin air distribution ducting, personal service units (PSU) and ceilings have traditionally been designed as individual components, with other functional components, such as air conditioning ducting components and lighting components secured to them by additional mounting brackets that, taken together for the entire aircraft, can contribute significant undesirable weight to the overall weight of the aircraft.

It would be desirable to provide a fully integrated commercial aircraft interior module that can be connected to existing aircraft structures to reduce the weight of such a fully integrated commercial aircraft interior module so as to contribute to overall aircraft weight reduction by elimination of secondary brackets, and to reduce installation time for retrofitting commercial aircraft interiors.

It would also be desirable to provide a fully integrated commercial aircraft interior module that can be retrofitted to existing aircraft support structures to provide increased structural capability of the commercial aircraft interior installation. The present invention meets these and other needs.

The overhead stowage bins or compartments may be pivot type overhead stowage bins or compartments, as is illustrated in FIGS. 11-15.

In a presently preferred aspect, one or more personal service units (PSU) 146 are preferably mounted beneath one or both of the right and left overhead stowage bins or compartments. The integrated aircraft interior module also preferably includes covered washlights 148, which may be mounted to an upper portion of the sidewall lining portions and on the overhead stowage bins or compartments near the ceiling portion.

All of these components are designed, fabricated, and fully pre-assembled to reduce the labor hours and parts required during the installation process into the aircraft, and attach to existing aircraft structural provisions. The sidewall linings with the integrated items also attach and interface with existing aircraft structural provisions. As is illustrated in FIG. 13, the “Pivot Bin” overhead stowage compartments (OHSC) also includes integrated electrical wiring 152 that connects to electrically powered components.

Both of these overhead stowage compartment solutions described above utilize the same design integration principles described above, and also utilize many of the same parts. The individual components that comprise the overall aircraft interior are provided as a complete product kit. This results in a reduction of labor hours required during installation by providing pre-assembled elements that require fewer procedures and parts required to complete the installation of the aircraft interior. The overhead stowage compartments (OHSC) come pre-installed with integrated lighting, electrical connection interfaces, PSU panels and integrated air distribution. This alleviates the need to install separate lighting, air distribution ducts/plenums/provisions and PSU panels. Sidewall linings come with integrated air distribution and integrated decompression panels. This alleviates the need to install air distribution ducts/plenums/attachment hardware and also alleviates the need to separately install the decompression (Dado) panels.

The integrated aircraft interior of the present invention provides for increased OHSC volume and capacity, overhead lighting that shines on open OHSC doors when the doors are in an open position, and pre-installed integrated lighting, Personal service units, air distribution and electrical wiring. The integrated aircraft interior of the present invention will reduce the labor hours and parts required for installation of aircraft interior products; and since air distribution riser ducts and related attachment parts no longer need to be installed and attached to the frames of the aircraft during the installation process, and PSU panels no longer need to be installed into the OHSC during the installation process, the time and parts required for installation will be further reduced.

It will be apparent from the foregoing that while particular forms of the invention have been illustrated and described, various modifications can be made without departing from the spirit and scope of the invention.
