Abstract

A lavatory for an aircraft cabin includes a wall having a forward wall portion disposed immediately aft of and substantially conforming to an exterior aft surface of an aircraft cabin structure, such as a passenger seat, that is substantially not flat in a vertical plane. The forward wall portion includes a forward projection over an aft portion of the adjacent passenger seat. The forward wall portion can define a secondary space in the interior lavatory space, which can provide an amenity stowage space, and can include design elements providing visual space.

First claim

What is claimed is:

1. An enclosure for a cabin of an aircraft, comprising:
an aft wall; and
a forward wall comprising:
an upper portion;
a lower portion; and
a middle portion below the upper portion;

wherein the lower portion of the forward wall is adapted to receive at least a portion of a seat support of a seat aftward of at least a portion of the lower portion for mounting the seat support to the aircraft; and
wherein the forward wall is adapted to receive loads from a structure within the cabin.

2. The enclosure of claim 1 , wherein the forward wall is adapted to be positioned adjacent the structure without a gap.

3. The enclosure of claim 1 , wherein the forward wall is adapted to receive loads from the seat.

4. The enclosure of claim 1 , wherein the forward wall is adapted to receive loads from an adjacent structure exterior of the enclosure.

5. The enclosure of claim 1 , wherein a forward surface of the forward wall is shaped to substantially conform to a shape of the upwardly and aftwardly inclined seat back of the seat.

6. The enclosure of claim 5 , wherein an aft-facing surface of the lower portion is accessible from the interior.

7. The enclosure of claim 5 , wherein an aft-facing surface of the middle portion is accessible from the interior.

8. The enclosure of claim 5 , wherein at least an aft-facing surface of the upper portion, an aft-facing surface of the middle portion, and an aft-facing surface of the lower portion of the forward wall are accessible from an interior of the enclosure.

9. The enclosure of claim 1 , wherein the middle portion defines an upper recess aftward of at least a portion of the lower portion.

10. The enclosure of claim 9 , wherein the upper recess is adapted to receive at least a portion of an exterior aft surface of a seat back of the seat when the seat back is in an upright and not a reclined position.

11. The enclosure of claim 1 , wherein an aft-facing surface of the upper portion defines an interior secondary space aftward of the aft-facing surface of the upper portion.

12. The enclosure of claim 1 , wherein the enclosure comprises a lavatory;
wherein the forward wall extends from a floor to a ceiling of the cabin; and
wherein the structure is mounted within the cabin independent from the lavatory and the forward wall.

13. An enclosure for a cabin of an aircraft, comprising:
an aft wall; and
a forward wall comprising:
an upper portion;
a lower portion; and

a middle portion below the upper portion;
wherein the lower portion of the forward wall is adapted to receive at least a portion of a seat support of a seat aftward of at least a portion of the lower portion for mounting the seat support to the aircraft; and
wherein the forward wall is configured to be positioned adjacent a structure within the cabin without a gap and accept loads from the structure.

14. The enclosure of claim 13 , wherein the structure comprises the seat.

15. The enclosure of claim 13 , wherein the structure is exterior of the enclosure.

16. The enclosure of claim 13 , wherein the middle portion defines an upper recess aftward of at least a portion of the lower portion.

17. An enclosure for a cabin of an aircraft, the cabin having an aircraft passenger seat positioned forward of and adjacent to the enclosure, the enclosure comprising:
an aft wall; and
a forward wall, wherein an interior of the enclosure is disposed between the aft wall and the forward wall, the forward wall comprising:
an upper portion;
a middle portion below the upper portion, the middle portion including a flat portion; and
a lower portion below the middle portion;

wherein the lower portion comprises a downward extending vertical portion, and wherein a seat support of the aircraft passenger seat is secured aft of the downward extending vertical portion, the seat support configured to interface with a floor of the cabin and hold a seat bottom of the aircraft passenger seat in an elevated position.

18. The enclosure of claim 17 , wherein the middle portion defines an upper recess.

19. The enclosure of claim 18 , wherein the flat portion of the middle portion defines an aft-most portion of the upper recess and the portion of an exterior aft surface of the seat back is an upper seat back such that the aft-most portion of the upper recess is parallel to an aft surface of the upper seat back when the seat back is in an unreclined position.

20. The enclosure of claim 17 , wherein the forward wall is configured to accept loads from a structure adjacent the enclosure.

21. The enclosure of claim 20 , wherein the enclosure is configured to be positioned adjacent a portion of the structure with no gap.

22. The enclosure of claim 20 , wherein the structure comprises the aircraft passenger seat.

23. The enclosure of claim 12 wherein the forward wall is adapted to be positioned adjacent the structure without a gap.

24. The enclosure of claim 13 , wherein the enclosure comprises a lavatory;
wherein the forward wall extends from a floor to a ceiling of the cabin; and
wherein the structure is mounted within the cabin independent from the lavatory and the forward wall.

25. The enclosure of claim 17 , wherein the enclosure comprises a lavatory;
wherein the forward wall extends from a floor to a ceiling of the cabin; and
wherein the structure is mounted within the cabin independent from the lavatory and the forward wall.

26. The enclosure of claim 25 wherein the forward wall is adapted to be positioned adjacent the structure without a gap.
