## Background
FIELD
Embodiments of the present disclosure relate generally to seating design. More particularly, embodiments of the present disclosure relate to aircraft seating design.
BACKGROUND
Due to aerodynamic and weight limits, commercial aircraft generally have a limited interior volume. The limited interior volume generally further limits an available floor space and space for seating. Commercial aircraft are generally configured in a linear configuration of rows and columns of seats.
SUMMARY
A forward concave trapezoidal seating system and methods are presented. Trapezoidal seats comprise a front side smaller than a rear side. The trapezoidal seats are aligned in a forward arc from a straight seat to a most-angled seat from among the trapezoidal seats. A straight side of the straight seat is configured to substantially align with a center line of an aircraft fuselage. A most-angled side of the most-angled seat is angled inboard relative to the straight side, and the most-angled seat is outboard of the straight seat. A side unit is coupled to the most-angled side and supports the trapezoidal seats.
Current seating generally assumes a floor area taken by a passenger is a rectangle. Embodiments of the disclosure provide a curved seating arrangement using trapezoidal wedges allowing greater seat width without decreasing a quantity of seats which can be fit into an airplane cabin zone. Embodiments of the disclosure also provide triangular side stowage units without decreasing seat width. Furthermore, embodiments of the disclosure increase a number of seats that may be fit in a seating area. A triangular shaped passenger sidewall floor storage bin is enabled via using trapezoid shaped seat cushions on passenger seats placed in a curved seating row.
In an embodiment, a forward concave trapezoidal seating system comprises trapezoidal seats. The trapezoidal seats comprise a front side smaller than a rear side, and the trapezoidal seats are aligned in a forward arc from a straight seat to a most-angled seat.

FIG. 3 is an illustration of an isometric view of an interior such as the interior 222 of a passenger area 300 of an aircraft such as the aircraft 200 showing an exemplary curved seating arrangement according to an embodiment of the disclosure. FIG. 4A is an illustration of a plan view of the interior 222 of the passenger area 300 of the aircraft 200 showing an exemplary curved seating arrangement according to an embodiment of the disclosure.
The passenger area 300 comprises a floor 302, a ceiling 304 and sidewalls 310 fitted inside a fuselage between a front end 312 and a rear 314. The passenger area 300 comprises passenger chair seating such as the seats 316, each of which have a trapezoidal base 318, a back 320 and arm rests 322. The seats 316 are arranged in a row wherein the seats 316 are adjacent to each other, and which are spaced along two aisles 324/326 in a transverse direction thereto. Each of the seats 316 (trapezoidal seats 316) may be wider at a rear side 422 of each of the trapezoidal seats 316 than a front side 424 of the trapezoidal seats 316. Furthermore, the trapezoidal base 318 at the back 320 of the trapezoidal seats 316, where a passenger 340 torso rests, is wider than the front side 424 of the trapezoidal seats 316 where legs of the passenger 340 are positioned.
As used wherein, a row may comprise a group of adjacent seats that need not be in a strict straight line linear arrangement, and a row may mean a curved row. Row, curved row, seating row and curved seating row may be used interchangeably in this document.
A line 416 from the outboard aisle seat 330 to one of sidewall seats 334 is at a non-perpendicular angle 418 to the adjacent sidewall 310 and the aisle 324/326, providing an open area 420 next to the adjacent sidewall 310. The non-perpendicular angle 418 may comprise, for example but without limitation, greater than about 99 and less than about 100 degrees such as about 99.75 degrees. The open area 420 allows locating a triangular shaped passenger floor storage bin 342 (floor storage unit 342) coupled to each of the sidewalls 310. A size of the open area 420 and the floor storage unit 342 may depend on a spacing between seat rows (row pitch, see 902 in FIG. 9). For example, a front row or an exit row may have a larger row pitch and thus comprise more room for the floor storage unit 342.
In an embodiment, the trapezoidal seats 316 are aligned in a forward arc 426 from a straight seat from among the trapezoidal seats 316 to a most-angled seat from among the trapezoidal seats 316. The most-angled seat is located outboard of the straight seat. The straight seat may be the outboard aisle seat 330 and the most-angled seat may be the sidewall seat 334. Alternatively, the straight seat may comprise a row center seat 352 and the most-angled seat may be a center section aisle seat 350.
A straight side 430 of the straight seat is configured to substantially align (in parallel with) with a center line 428 of a fuselage of the aircraft 200 (FIG. 2). A most-angled side 432 of the most-angled seat is angled inboard relative to the straight side 430, where the most-angled seat is located outboard of the straight seat.
A side unit such as the triangular shaped passenger floor storage bin 342 comprising a storage space, or a side support unit 344 may be coupled to the most-angled side 432 to support the trapezoidal seats 316.
The most-angled seat is aligned at an angle that reduces an effect of a centrifugal force, a yaw force, and/or a roll force on the passenger 340. The most-angled seat may be the sidewall seat 334 and/or a center section aisle seat 350 (also shown in FIG. 4B).
FIG. 4B is an illustration of an expanded plan view of a portion of the interior 222 (FIG. 2) of the passenger area 300 of the aircraft 200 (FIG. 2) shown in FIG. 4A showing an exemplary curved seating arrangement in more detail according to an embodiment of the disclosure. FIG. 4B is described herein in conjunction with FIG. 3.
The aisles 324/326 comprise parallel longitudinal planes of symmetry 402 parallel with the center line 428. The center section aisle seats 350 are adjacent to one of the aisles 324/326 and comprise a respective plane of reference 464 of the center section aisle seat 350. The outboard aisle seats 330 are adjacent to one of the aisles 324/326 and comprise a respective plane of reference 404 of the outboard aisle seat 330. The sidewall seats 334 are adjacent to one of the sidewalls 310 and comprise a respective plane of reference 406 of the sidewall seat 334. Row center seats 328 are not adjacent to one of the aisles 324/326 or one of the sidewalls 310 and comprise a respective plane of reference 408 thereof. Depending on a cabin configuration of the passenger area 300, various numbers of the row center seats 328 may be between the center section aisle seat 350 and the sidewall seat 334.
The plane of reference 404 of each outboard aisle seat 330 is inclined with respect to the parallel longitudinal planes of symmetry 402 of the aisles 324/326 and the center line 428. The plane of reference 404 of each outboard aisle seat 330 forms an acute angle 410 relative to the parallel longitudinal planes of symmetry 402 and the center line 428 of, for example, more than about 4 degrees and less than about 5 degrees such as about 4.5 degrees opening towards the back 320 of the trapezoidal seats 316. The sidewall seats 334 are arranged differently. When a row has three seats, as shown in FIGS. 4A and 4B, the plane of reference 406 forms an acute angle 412 with the parallel longitudinal planes of symmetry 402 and the center line 428, opening towards the back 320 of the trapezoidal seats 316.
The acute angle 412 may comprise, for example, less than about 23 degrees, more than about 22 degrees and about 22.5 degrees opening towards the back 320 of the trapezoidal seats 316. The row center seats 328 which are not adjacent to an aisle nor to one of the sidewalls 310 each have a plane of reference 408 which forms an acute angle 414 with the parallel longitudinal planes of symmetry 402 and the center line 428. The acute angle 414 may comprise, for example, less than about 14 degrees, more than about 13 degrees and about 13.5 degrees opening towards the back 320 of the trapezoidal seats 316.
Each of the outboard aisle seats 330 (e.g., for multiple rows) in the outboard section 436 forms an angle 446 between a plane of reference 438 and a plane of reference 440. The plane of reference 438 of the outboard aisle seat 330 may be substantially parallel with the parallel longitudinal planes of symmetry 402 and the center line 428. The row center seats 328 in the outboard section 436 which are not adjacent to an aisle nor to one of the sidewalls 310 each forms an angle 448 between the plane of reference 438 and a plane of reference 442. Each of the sidewall seats 334 forms an angle 450 between the plane of reference 438 and a plane of reference 444.
Each of the center section aisle seats 350 in a center section 434 forms an angle 460 between a plane of reference 452 and a plane of reference 456. The plane of reference 452 may be substantially parallel with the parallel longitudinal planes of symmetry 402 and the center line 428. Center section straight seats 352 in the center section 434 are not adjacent to an aisle 324/326 nor to one of the sidewalls 310, and each forms an angle 458 between the plane of reference 452 and plane of reference 454.
Each angle is additive, so in one embodiment for example, the approximate angles 446, 448, and 450 may comprise about 9°, 18° and 27° respectively on the outboard section 436 (e.g., for three seats in a row), and angles 458 and 460 may comprise about 9° and 18° for the center section 434 respectively.
There is substantially not a single plane of symmetry through a middle of each of the trapezoidal seats 316. Thus, seats on a right hand side of an airplane may use an interchangeable seat cushion, and seats on a left hand side of the airplane may be a mirror dimensionally, but may not be interchangeable with the interchangeable seat cushion for the right hand side of the airplane. A configuration of seat angles can be used to create adequate clearance between seats without needing to increase a seat pitch. Seat cushion angles and relative angles between seats may be configured according to aircraft type.
FIGS. 4C-4D are illustration of expanded top views of seats on the the center section 434 and the outboard section 436 respectively according to embodiments of the disclosure.
FIG. 5 is an illustration of a large-scale plan view 500 of an exemplary row of three seats comprising the trapezoidal base 318 of a curved seating arrangement according to an embodiment of the disclosure compared to a row of three seats comprising a rectangular base 502 of an existing seating arrangement. The curved seating arrangement using the trapezoidal base 318 occupies a trapezoidal area 504 which is less than a rectangular area 506 occupied by the existing seating arrangement that uses the rectangular base 502. The smaller space occupied by the trapezoidal area 504 allows the floor storage unit 342 to be placed alongside the sidewall seat 334. In some embodiments, the trapezoidal seats 316 may be supported only by the floor storage unit 342. As shown in FIG. 5, the trapezoidal seats 316 comprising the sidewall seats 334, the row center seat 328 and the aisle seat 330, are suspended in a cantilever manner.
FIG. 6 is an illustration of various views 600 of an exemplary curved seating arrangement according to an embodiment of the disclosure. A first row seat 602 in a first row 604 can be adjusted back to fit between two seats in a second row 606 behind the first row 604. The first row seat 602 may comprise, for example, the outboard aisle seat 330 or a center seat such as the row center seats 328.
FIG. 7 is an illustration of a plan view 700 of an exemplary curved seating arrangement according to an embodiment of the disclosure.
FIG. 8 is an illustration of a perspective view 800 of an exemplary curved seating arrangement according to an embodiment of the disclosure.

FIG. 10 is an illustration of an exemplary curved seating arrangement 1000 showing a curved seating row 1002 according to an embodiment of the disclosure. The curved seating row 1002 may be located at the center section 434 comprising two of the center section straight seats 352 between the center section aisle seats 350. The curved seating row 1002 may further comprise two of the side support units 344 coupled to the center section aisle seats 350. In some embodiments, the curved seating row 1002 (e.g., trapezoidal seats 316 of the center section 434) may be supported only by the side support unit 344. As shown in FIG. 10, the curved seating row 1002 (trapezoidal seats 316) are suspended in a cantilever manner between the side support units 344.
FIG. 11 is an illustration of various views 1100 of an exemplary curved seating arrangement according to an embodiment of the disclosure. A first row seat in a first row can be adjusted back in an adjusted position 1102 to fit between two seats in the second row 606 behind the first row 604 as shown in FIG. 6 above. The straight seat may be the outboard aisle seat 330 or a center seat such as the row center seats 328.
In one embodiment, the trapezoidal seats 316 are supported only by a side unit such as the floor storage unit 342 or the side support unit 344. Also, trapezoidal seats 1104 comprise a first most-angled seat 1106 on a first side 1108 and a second most-angled seat 1110 on a second side 1112. A first side unit 1114 is coupled to the first most-angled seat 1106, and a second side unit 1116 is coupled to the second most-angled seat 1110. The trapezoidal seats 1104 are supported only by the first side unit 1114 and the second side unit 1116.
FIG. 12 is an illustration of an exemplary passenger floor storage bin 342 according to an embodiment of the disclosure.
FIG. 13 is an illustration of an exemplary side support unit 344 of a curved seating arrangement according to an embodiment of the disclosure.
FIG. 14 is an illustration of an exemplary curved seating arrangement showing an added space such as the open area 420 and an open exit space 1402 according to an embodiment of the disclosure.
FIG. 15 is an illustration of a plan view of an interior of a passenger area of an aircraft showing an exemplary curved seating arrangement 1502 according to an embodiment of the disclosure compared to an existing seating arrangement 1504. Current seating layouts assume a floor area taken by a passenger is a rectangle such as the rectangular base 502 shown in FIG. 5. Embodiments of the disclosure provide a curved seating arrangement using trapezoidal wedges such as the trapezoidal base 318 allowing greater seat width without decreasing a quantity of seats which can be fit into an airplane cabin zone. Embodiments of the disclosure also provide the triangular shaped passenger floor storage bin 342 without decreasing seat width. The triangular shaped passenger floor storage bin 342 is enabled via using trapezoid shaped seat cushions on the trapezoidal seats 316 placed in a curved seating row such as the curved seating row 1002 shown in FIG. 10.
FIG. 16 is an illustration of a plan view of an interior of a passenger area of an aircraft showing an exemplary curved seating arrangement 1502 according to an embodiment of the disclosure compared to the existing seating arrangement 1504. Thus, in contrast to the curved seating arrangement 1502, no added space such as the open area 420 is available in the existing seating arrangement 1504.
