Referring now to the drawings (the presentation here is for the purpose of illustrating the invention and not for the purpose of limiting it), FIGS. 1 shows an aircraft lavatory monument assembly 10 that provides a generally V-shaped passenger footprint 14 and door 40.
In a preferred embodiment, the lavatory monument assembly includes a first wall 28, a second wall 30, a third wall 31, and a fourth wall 26 (and an optional ceiling 33).

As shown in FIGS. 1-3, in a preferred embodiment, the fourth wall 26 includes a first portion 26a and a curved second portion 26b.
In other words, in this embodiment, lavatory monument assembly 10 does not have a rectangular footprint.
As can be seen from FIG. 2, the toilet defines a vertical plane P1 that divides the toilet, and the toilet is positioned such that the vertical plane P1 is not parallel to the third wall 31 (FIG. 2). And angle θ).
The orientation of the angled toilet 12 and the generally V-shaped passenger footprint can increase comfort in a lavatory with a relatively small footprint. This means that the width of the lavatory at the back of the toilet is minimal (see first wall 28), as shown in FIG. 2 and in another preferred embodiment depicted in FIG. And the wider front dimension of the toilet (see second wall 30).
Conventional lavatory monuments generally have a rectangular footprint.
An increase in passenger area can also be achieved by providing a toilet 12 that is positioned at an angle, as best seen in FIG.
In other words, the toilet 12 is shaped such that the vertical planes that divide the toilet 12 are not parallel (when positioned as shown in FIG. 1) and form an angle with the front wall of the lavatory monument assembly. Is angled by.
Thus, a passenger sitting in the toilet 12 can use the additional space created by the curved fourth wall 26.
However, this is not a limitation on the present invention, and the toilet can also be arranged in such a way as to face straight in the in-flight direction.
FIG. 2 shows a potential layout of the aforementioned lavatory monument assembly 10 in an aircraft cabin.

  FIG. 3 shows a comparison between the lavatory monument assembly 10 of the present invention and a conventional lavatory monument 200, where the exit door 34 has sufficient space for possible space savings and entry and exit according to applicable FAA regulations. It shows the possibility that airlines can add more than one row while offering before.

As shown in FIG. 3, with the arrangement of the lavatory monument assembly 10 of the present invention, there is a gap between the rear wall of the lavatory monument assembly 10 and the wall behind it (or a seat row or other object). A suitable amount of exit space is provided.
According to the area occupied by the lavatory monument assembly 10, the entire lavatory monument assembly 10 can be positioned behind the location where the conventional lavatory monument was located.
As shown in FIG. 3, the second portion 26b allows the fourth wall 26 to curve around the exit door.
Adding additional seat rows by positioning the lavatory monument assembly 10 behind the location where prior art monuments are located and reducing exit space (but still allowing full compliance with the rules) can do.

FIG. 2 illustrates a possible arrangement of the lavatory monument assembly in the aircraft, including the lavatory monument assembly in relation to the aircraft exit 34, and illustrates the intended space saving results that can be achieved by the present invention. ing.
As a result of space savings, the aircraft may be able to accommodate additional seats, thus increasing revenues and increasing seat pitch, or adding monuments in front of the lavatory.

4-5 show a lavatory behind the toilet rather than having a wider front dimension (see second wall 30) (as shown in FIG. 3 and also seen in FIG. 4). Another preferred embodiment for achieving additional space by narrowing the width (see first wall 28) is shown.
As shown in FIG. 4, the additional space achieved can be used to create a compartment or alcove 38 that can include a fixture or component therein.
In a preferred embodiment, the sink 32 is positioned within the alcove 38.
However, this is not a limitation on the present invention.
Installing the sink 32 in this position may be desirable in some embodiments of the present invention because it can provide additional room for passengers in the lavatory in the area immediately before the toilet 12.
As described above, the sink 32 can be installed at this position because the overall size of the second wall 30 is wider than that of the first wall 28.
In another embodiment, it will be appreciated that the first wall 28 may have a wider / longer dimension than the second wall 30 or they may have equal lengths.
Furthermore, by positioning the sink 32 within the alcove 38, a shoulder room is maintained in the area close to the periphery of the toilet 12.

It is contemplated that the preferred embodiment depicted in FIG. 4 includes a door positioned on one of the walls of the lavatory monument assembly similar or identical to the door 40 depicted in FIGS. Is and is intended.
As shown in FIG. 4, in a preferred embodiment, the fourth wall 26 includes a first portion 26a, a second portion 26b, and a third portion 26c.
The first portion 26a, the second portion 26b, and a portion of the second wall 30 cooperate to define an alcove 38.
In a preferred embodiment, the sink 32 is positioned within the alcove 38 such that any components associated with the sink (eg, drains, cabinets, mirrors, etc.) are all positioned within the alcove 38.

FIGS. 4-5 also illustrate the flight attendant assist space 36 required for most aircraft.
FIG. 4 shows that the assist space 36 is maintained by positioning the alcove 38 in the inboard direction of the first wall 28 and outlet 34.
