## Background
CROSS-REFERENCES TO RELATED APPLICATIONS
This application is based upon and claims priority from U.S. Application No. 61/821,895, filed May 10, 2013, incorporated by reference in its entirety.


BACKGROUND OF THE INVENTION
This invention relates to aircraft enclosures, and more particularly relates to an aircraft stowage unit, and more particularly relates to an aircraft cabin stowage compartment that is attached to a wall of an aircraft cabin interior commodity or monument, such as a lavatory, galley, or closet.
In a conventional prior art installation of an interior monument such as a lavatory immediately aft of and adjacent to an aircraft passenger seat, a seat track mounted stowage box, such as for emergency equipment, miscellaneous items or the like, is commonly located in an area between the last or aft most seat-row of aircraft passenger seating and the interior monument. However, in some cases, the aft most seat is placed in such close proximity to the interior monument that insufficient space is available for a seat track attachment for the installation of such a stowage box.
The last or aft most seat-row of an aircraft passenger cabin typically does not allow the stowage of passenger carry-on items under the seat-row, and typically overlaps or projects beyond a side wall of the interior monument in a manner that allows access to an area under the seating from an aft portion of the seating. However, such space is typically unused on many aircraft. In addition, the current introduction of contoured walls on aircraft interior commodities or monuments adjacent to such passenger seating also increases the likelihood that the last or aft most seats will be placed sufficiently close to the adjacent commodities or monuments to essentially eliminate space for stowage between the last or aft most row of seating and the adjacent commodities or monuments.
It would be desirable to provide a wall mounted stowage compartment that makes use of the otherwise unused space available under a last or aft most row of passenger seats adjacent to or in close proximity to a forwardly facing wall of an aircraft cabin monument. It also would be desirable to provide such a wall mounted stowage compartment that attaches to an aft, forwardly facing interior monument wall, to recover the capability to stow items in this location, such as emergency equipment, other miscellaneous items and the like. The present invention meets these and other needs.
SUMMARY OF THE INVENTION
Briefly, and in general terms, the invention provides for a wall mounted stowage compartment for a passenger cabin of an aircraft, having a forwardly facing interior monument wall and a last or aft most passenger seat in a last row or aft most row of passenger seats.
The present invention accordingly provides for a wall mounted stowage compartment that includes a housing having a rearwardly facing wall that is mounted to the forwardly facing interior monument wall. The stowage compartment is located under and extends under the last or aft most passenger seat in the last row or aft most row of passenger seats, which are preferably adjacent to or in close proximity to the forwardly facing interior monument wall.
In a presently preferred aspect, the aircraft cabin monument comprises a lavatory. In another presently preferred aspect, the aircraft cabin monument also includes a side wall and a monument or lavatory door in the side wall. In another presently preferred aspect, the passenger seat includes a seat back having an aft portion with a rearwardly facing aft most exterior surface that is substantially not flat in a vertical plane and generally conforming to a shape of a forwardly facing recess formed in the forwardly facing interior monument wall that is also substantially not flat in the vertical plane. In another presently preferred aspect, the seat back has an upright position and a reclined position such that rearwardly facing aft most exterior surface of the seat back extends within the forwardly facing recess.
In another presently preferred aspect, the stowage compartment includes a stowage compartment drawer. In another presently preferred aspect, a protective breathing equipment compartment or emergency medical kit is mounted to the side wall of the aircraft cabin monument, which includes a forwardly facing edge that generally follows a contour of the forwardly facing wall of the aircraft cabin monument extending from the forwardly facing recess to the floor of the cabin.
Other features and advantages of the present invention will become apparent from the following detailed description of the preferred embodiments in conjunction with the accompanying drawings, which illustrate, by way of example, the operation of the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to the drawings, which are provided for purposes of illustration and by way of example, the present invention provides for stowage compartment 10 for a passenger cabin 12 of an aircraft (not shown). The stowage compartment includes a housing 14 having a rearwardly facing wall 16, and preferably includes a drawer 18 that is slidably contained within the housing. The passenger cabin includes an aircraft cabin monument 20 such as a lavatory, having a forwardly facing interior monument wall 22, and typically having a side wall 24 and a monument or lavatory door 26, although the aircraft cabin monument may also be an aircraft closet, or an aircraft galley, or another similar enclosed or structurally defined space, for example.
The stowage compartment preferably is mounted to the forwardly facing interior monument wall under a last or aft most passenger seat 28 such as in a last row or aft most row of passenger seats 30 located adjacent to or in close proximity to the forwardly facing interior monument wall. The housing of the stowage compartment preferably is located under and extends under the aft most passenger seat in the last row or aft most row of passenger seats adjacent to the forwardly facing interior monument wall. The last or aft most passenger seat includes a seat back 32, having an aft portion 34 with a rearwardly facing aft most exterior surface 36 that is substantially not flat in a vertical plane, and that generally conforms to a shape of a forwardly facing recess 38 formed in the forwardly facing interior monument wall, that is also substantially not flat in the vertical plane. As is illustrated in FIG. 1, the seat back has an upright position 40 and a reclined position 42 such that the rearwardly facing aft most exterior surface of the seat back extends within the forwardly facing recess. The passenger seat also preferably includes a seat cushion 44 and an arm rest 46. As is illustrated in FIG. 5, the seat back typically overlaps and extends beyond the side wall of the aircraft cabin monument, and the arm rest typically overlaps and extends beyond a protective breathing equipment (PBE) compartment 50 that is mounted to the side wall of the aircraft cabin monument, although the protective breathing equipment compartment may alternatively house an emergency medical kit or other equipment, for example. The protective breathing equipment compartment may optionally be formed as a part of the stowage compartment or may be connected to or mounted to the stowage compartment. Referring to FIG. 4, the protective breathing equipment compartment typically includes a protective breathing equipment door 52 providing access to oxygen bottles 54 and a protective breathing equipment hood or mask (not shown). The protective breathing equipment compartment typically includes a forwardly facing edge 56 that generally follows the contour of the forwardly facing wall of the aircraft cabin monument extending from the forwardly facing recess to the floor 58 of the cabin. Referring to FIG. 3, a seat track 60 is also provided adjacent to the stowage compartment under the last row or aft most row of passenger seats for mounting of the last row or aft most row of passenger seats to the floor of the cabin.
As should be readily apparent, it would also be possible to make the stowage compartment drawer longer, or to add a smaller stowage compartment door above the stowage compartment drawer. The oxygen bottles may also be accommodated in the stowage compartment drawer, which can be large enough for protective breathing equipment or emergency medical kit or other equipment, or other miscellaneous items of a similar size. The stowage can also be taller in areas where the aisle clearance permits, and the door of the monument or lavatory may be a bi-fold, articulating or translating type of door to avoid interference of opening of the door with the protective breathing equipment compartment or stowage compartment.
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. Accordingly, it is not intended that the invention be limited, except as by the appended claims.
