DETAILED DESCRIPTION

[0027] The subject matter of embodiments of the present invention is described here with specificity to meet statutory requirements, but this description is not necessarily intended to limit the scope of the claims. The claimed subject matter may be embodied in other ways, may include different elements or steps, and may be used in conjunction with other existing or future technologies. This description should not be interpreted as implying any particular order or arrangement among or between various steps or elements except when the order of individual steps or arrangement of elements is explicitly described.

[0028] While the embodiments of seat units may be described with reference to an aircraft cabin, they are by no means so limited. In fact, the seat units may be used in conjunction with any type of vehicle cabin or otherwise as desired.

[0029] According to certain embodiments of the present invention, as illustrated in FIGS. 2-7, a cabin 10 comprises an aircraft cabin arrangement 12 formed by at least one lavatory unit 14, at least one first class seat unit 16, and at least one business class seat unit 18.

[0030] In these embodiments, the lavatory unit 14 comprises a first side wall 1402 and a second side wall 1404. In certain embodiments, the first side wall 1402 comprises a monument 1406, which includes a sink 1408 and a counter 1410. Thus, a person inside the lavatory unit 14 may make use of the area above the counter 1410 and sink 1408. The first side wall 1402 may have an irregular shape, as shown in FIGS. 2, 6-7, with a protruding portion 1412 and a recessed portion 1414. The protruding portion 1412 is shaped to contour the portion of the monument 1406 requiring greater depth for the sink 1408, and the recessed portion 1414 is shaped to contour the portion of the monument 1406 that requires less depth.

[0031] In some embodiments, the first class seat unit 16 comprises a seat back 1602, a seat pan 1604, and a secondary seat or foot rest 1606. The seat back 1602 and the seat pan 1604 are partially surrounded by a shell 1608. A recessed area 1610 may be located within the shell 1608 to one side of the seat back 1602 and the seat pan 1604. The shell 1608 may be configured to also at least partially surround the foot rest 1606.

[0032] In certain embodiments, as illustrated in FIG. 2, 6-7, the first class seat unit 16 may be positioned adjacent the first side wall 1402 of the lavatory unit 14. In this arrangement, the foot rest 1606 may be positioned within and coupled to the recessed portion 1414 of the first side wall 1402 of the lavatory unit 14. The shell 1608 may also couple to an end of the recessed portion 1414 of the first side wall 1402 to provide continuity to the enclosure for to the first class seat unit 16.

[0033] As a result, the recessed portion 1414 of the lavatory unit 14 is fully utilized for the foot rest 1606 and a separate wall between the lavatory unit 14 and the first class seat unit 16 is eliminated. In certain embodiments, the first side wall 1402 may further include some or all of the foot rest 1606, a monitor, sockets, stowage, and/or any other first class amenity typically provided within the front wall of a first class seat unit 16.

[0034] The business class seat unit 18 comprises a seat back 1802, a seat pan 1804, and a foot well 1806. The seat back 1802 and the seat pan 1804 are partially surrounded by a shell 1808. A recessed area 1810 may be located within the shell 1808 to one side of the seat back 1802 and the seat pan 1804.

[0035] In certain embodiments, as illustrated in FIGS. 2-7, the business class seat unit 18 may be positioned adjacent the shell 1608 of the first class seat unit 16. In this arrangement, the foot well 1806 may be positioned within and coupled to the recessed area 1610 in the shell 1608 of the first class seat unit 16. As a result, the recessed area 1610 is fully utilized for the foot well 1806 and a separate wall between the first class seat unit 16 and the business class seat unit 18 is eliminated.

[0036] In other words, the shell 1608 of the first class seat unit 16 has taken on the function of a business class seat unit 18 front row monument. In certain embodiments, the shell 1608 may further include some or all of the foot well 1806, a monitor, sockets, stowage, and/or any other business class amenity typically provided within a front row monument of a business class seat unit 18.

[0037] In further embodiments, an economy class seat unit (not shown) may be positioned adjacent the shell 1808 of the business class seat unit 18 or adjacent the shell 1608 of the first class seat unit 16. As a result, a separate wall between the economy class seat unit and either the business class seat unit 18 or the first class seat unit 16 is eliminated.

[0038] In this arrangement, the shell 1808 of the business class seat unit 18 or the shell of the first class seat unit 16 may function as an economy class seat unit front row monument. In certain embodiments, the shell 1808 or the shell 1608 may further include some or all of a monitor, sockets, stowage, tray table, and/or any other economy class amenity typically provided within a front row monument of an economy seat unit.

[0039] In further embodiments, the business class seat unit 18 may be positioned adjacent the first side wall 1402 of the lavatory unit 14. In this arrangement, the foot well 1806 may be positioned within and coupled to the recessed portion 1414 of the first side wall 1402 of the lavatory unit 14. As a result, the recessed portion 1414 of the lavatory unit 14 is fully utilized for the foot well 1806 and a separate wall between the lavatory unit 14 and the business class seat unit 18 is eliminated. As a result, the first side wall 1402 may further include some or all of the foot well 1806, a monitor, sockets, stowage, and/or any other business class amenity typically provided within a front row monument of a business class seat unit 18.

[0040] In further embodiments, an economy class seat unit (not shown) may be positioned adjacent the first side wall 1402 of the lavatory unit 14. As a result, a separate wall between the lavatory unit 14 and the economy class seat unit is eliminated. In this arrangement, the first side wall 1402 of the lavatory unit 14 may function as an economy class seat unit front row monument. As a result, the first side wall 1402 may further include some or all of a monitor, sockets, stowage, tray table, and/or any other economy class amenity typically provided within a front row monument of an economy seat unit.

[0041] In the embodiments where the shell of one seat unit is used to also function as a divider between two classes of seat units, the shell may be modified to include a vertical panel 22. The vertical panel 22 is shaped to extend upward toward the ceiling of the cabin to a greater height than the remainder of seat unit. In some embodiments, an upper surface 2202 and at least one side surface 2204 of the vertical panel 22 may be shaped to contour to the surface of the cabin. The vertical panel 22 may further include a substantially straight surface 2206, which may border an aisle 20. Thus, from the perspective of a passenger seated in the seat unit located behind the shell, the vertical panel 22 provides the appearance of a separate divider wall positioned between the classes.

[0042] Any suitable arrangement of seat units may be used with the arrangement 12. For example, the seat units 16, 18 may be angled, staggered, forward facing, aft facing, or any combination thereof. Furthermore, arrangement 12 may be used with both central seats (seats positioned between aisles) and lateral seats (seats positioned between an aisle and a wall of the cabin), as well as seats facing longitudinally or traversely.

[0043] By eliminating the monuments, dividers, etc. between classes in the cabin, the arrangement 12 gains additional longitudinal space within the cabin 10 in the range of about 1 inch to about 40 inches, further in the range of 15 inches to about 25 inches, and even further in the range of about 20 inches.

[0044] Different arrangements of the components depicted in the drawings or described above, as well as components and steps not shown or described are possible. Similarly, some features and sub-combinations are useful and may be employed without reference to other features and sub-combinations. Embodiments of the invention have been described for illustrative and not restrictive purposes, and alternative embodiments will become apparent to readers of this patent. Accordingly, the present invention is not limited to the embodiments described above or depicted in the drawings, and various embodiments and modifications may be made without departing from the scope of the claims below.
