Description
- A variety of passenger seating systems for aircrafts have been proposed, including GB2326824 and EP1417113. These show “herringbone” arrangements of seat units. Due to the space limitations on an aircraft, there is a desire for each seat unit to take up a minimum amount of space, such that a higher number of seat units can be installed in a given floor area of an aircraft.
- The seat units can be configured in a bed mode and a seat mode. The bed mode enables the passenger to lie in a recumbent position on a bed, while the seat mode enables the passenger to sit in a seated position on a seat. Some components that form the seat may also form the bed, and vice versa. There is also a desire to ensure that the bed is of a sufficient length to accommodate even a relatively tall person.
- It has been appreciated by the inventors that there are disadvantages with the above arrangements and that improvements can be made.
- One embodiment of the present invention includes an aircraft seating system including a plurality of personal units, with each personal unit including a seat having a top portion and bottom portion, a central partition extending along one side of the seat from a rear surface of the seat to an area in front of the seat, a surface between the central partition and the seat, with the surface affixed to the central partition at a predetermined height, where the personal units are arranged in a first column and a second column along a central axis such that each personal unit includes a side aligned with the central axis, and the predetermined height of the surface is configured such that a passenger in a first personal unit may insert their legs and feed into the space below the surface of a second personal unit in front of the first personal unit.
- In another embodiment, the central partition includes a first extension portion having one side substantially perpendicular to a side of the seat, a second extension portion extending substantially perpendicularly from an edge of the first extension portion on a side of the first partition furthest from the seat, and a third extension portion extending substantially perpendicularly from an edge of the second extension portion furthest from the first extension portion such that a surface of the third extension portion faces a front surface of the seat.
- In another embodiment, the first extension portion connects to the second connection portion via a curved surface.

- In another embodiment, the surface is positioned above an arm of the seat.
- In another embodiment, the surface is positioned below an arm of the seat.
- In another embodiment, the second partition in each personal unit is aligned such that they form a central axis with the central axis being substantially parallel with a first column axis of the first column of personal units and second column axis of a second column of personal units.
- In another embodiment, the seat of each personal unit is aligned with the space created by the surface of another personal unit along a longitudinal axis.
- In another embodiment, the longitudinal axis is angled from the central axis by a predetermined angle.
- In another embodiment, the central partition has a substantially wave shaped form.

Thesecond partition 310 in eachpersonal unit 100 acts as a common partition such that thesecond partition 110 forms a portion of at least twopersonal units 100. Thepersonal units 100 are arranged along acentral axis 316 with a first row of personal units being angled along alongitudinal axis 304 at a first angle from the central axis and a second row of partitions being angled along alongitudinal axis 304 at a second angle such that the seat portion of onepersonal unit 300 in the first or second column is adjacent to the surface area portion in an adjacentpersonal unit 100. -
FIG. 4 depicts another embodiment of apersonal unit 400. Eachpersonal unit 400 includes aseat 402 having apartition 404 extending along the side and back surfaces of theseat 402. In one embodiment, thepartition 404 is configured such that the peripheral vision of a person seated in the seat is obscured. Eachpartition 400 is arranged along acentral partition 406. In one embodiment, thecentral partition 406 is substantially wave shaped. Afirst surface unit 408 is position between thecentral partition 406 and theseat 402 and asecond surface unit 410 extends from an end of thefirst surface unit 408 furthest from theseat 402 such that an edge of thesecond surface unit 410 is parallel with the front surface of theseat 402. -
FIG. 5 depicts a top view of the personal units ofFIG. 4 . Thepersonal units 400 are in afirst column 502 along afirst column axis 504 and asecond column 506 along asecond column axis 508 on either side of acentral axis 510 extending down the length of thecentral partition 406. Thelongitudinal axis 512 of each seat is angled from the first column axis or second column axis by an angle β. In one embodiment, the angle β is substantially equal for eachpersonal unit 400. In another embodiment, the angle β is different for eachpersonal unit 400 -
FIG. 6 depicts a side view of thepersonal units 400 ofFIG. 4 . Eachpersonal unit 400 is separated into three layers with each layer being substantially parallel to the floor. The layers are stacked one on top of another, with the floor at the bottom. The lowest layer is thefloor space layer 600, then the foot space layer is next upwards (i.e. in a direction perpendicular to the floor), then the side space layer is at the top. The boundary between the first column and the second column is differently structured in at least two of the respective layers. This results in a situation in which a personal space in one layer of one personal unit is partially stacked with respect to a personal space in another layer of one personal unit in the other column. Thus portions of each personal space cross a notional central plane normal to the floor and between the column axes, resulting in a stacked arrangement of portions of personal space in the region of the notional central plane, as described above. - The boundary between the first and second columns in a respective layer is formed at least partially by a partition between the columns. Different partitions in at least two different layers are structured differently. Each partition may be, for example, substantially straight (e.g. running parallel to the column axes), or may be, for example, corrugated. The corrugation may be curved, like a sine wave when viewed from above, or may be zig-zagged, like a triangular wave when viewed from above.
- The
foot space layer 602 includes a foot space, in which the person inserts his feet when in the recumbent position. The foot space is at the forward end of the personal unit. By stacking the foot space with portions of personal space of adjacent personal units, in particular crossing the notional central place, a wider, longer foot space may be achieved. - The
side space layer 604 includes a side space, which the person can use and access (at least) when in the seated position. The side space is located to one side of the person when in this position. - The
floor space layer 600 includes a floor space. The floor space comprises a space in which the person will put his feet when in the seated position. In some embodiments, the floor space also comprises a space at least partially underneath the foot space, which may be used for storage. In some embodiments, the floor space comprises a space at least partially underneath the side space, which may be used for storage. The gap between these spaces may include part of the foot space of an adjacent personal unit in the same column and/or the foot space of a personal unit in the other respective column. - In the
foot space layer 600 and thefloor space layer 602, the central partition between the two columns is zigzagged. The zigzagging parts cross either side of the central partition in the side space layer. The foot space and the floor space of each personal unit therefore extends underneath the central partition in the side space layer. The floor space and the foot space of a respective personal unit extend in the forward direction until it reaches a partition defining a side of a respective personal unit in the other column. Each straight part of the zigzag therefore defines a forward end of the foot space and the floor space, respectively. The personal units are therefore arranged in these layers in an “interlocking herringbone” formation. The zigzag formed between the two columns has internal angles that are obtuse (e.g. 100°-170° or 120°-150°, which results in the forward end of the foot space and the floor space not being perpendicular to the sides of the personal unit. One side of the personal unit is therefore longer than the other, which results in a longer maximum length of the personal unit. In thefoot space layer 600, this creates a longer maximum length of the part of the personal space that is occupied by the person when in the recumbent position. (In other embodiments, the zigzag is formed of right-angles.) - In another embodiment, the side space layer, the central partition between the two columns is corrugated, such that the side space side partition extends substantially more parallel to the longitudinal axis of the personal unit than in the first embodiment. The shelf is therefore of a substantially uniform width, rather than being substantially triangular. The foot space layer and the floor space layer are structured similarly to the first embodiment, but with a more corrugated central partition.
- Each personal unit has the foot space, the floor space and the side space. All of these spaces form part of the personal space for that personal unit.
- As will be apparent, the
personal units 400 are arranged in an array of individualpersonal units 400, specifically including two columns of units in the described embodiments. The array is formed by a corresponding array of unit cells or personal space defining units in some embodiments. -
FIG. 7 depicts a perspective view of thepersonal unit 400 ofFIG. 4 . Thepersonal unit 400 includes theseat 402, thepartition 404, thecentral partition 406, thefirst surface 408 and thesecond surface 410. -
FIG. 8 depicts a rear view of thepersonal unit 400 ofFIG. 4 . Thecentral partition 406 curves away from thepartition 404 of thepersonal unit 400 to form afootrest portion 800 for an adjacentpersonal unit 402. Afootrest partition 802 extends from thecentral partition 406 to form theenclosed footrest portion 802. The footrest portion includes a footrest surface 804 connected to thefootrest partition 802. The edge of the footrest surface 804 is curved downward towards theaircraft floor 1. The footrest surface 804 is positioned at above the aircraft floor such that a space is formed between theaircraft floor 1 and the footrest surface 804. In one embodiment, the height of the footrest surface 804 above the floor is adjustable. In another embodiment, the height of the footrest surface 804 above the floor is fixed. - The
footrest partition 806 includes afront partition 812 formed by thefootrest partition 806, aside partition 814 formed by the portion of thepartition 404 adjacent to thefootrest partition 806, anupper footrest partition 816 formed by the portion of thecentral partition 406. The width of thecentral partition 406 may be increased to form theupper footrest partition 816. -
FIG. 9 depicts a top view of thepersonal units 400 ofFIG. 4 with aperson 900 seated in a seat of thepersonal unit 400.FIG. 10 depicts a top view of thepersonal units 400 ofFIG. 4 with a reclinedperson 1000 in theseat 402 of thepersonal unit 400.FIG. 11 depicts a top view of thepersonal unit 400 depicting thefloor space 1100 exposed in eachpersonal unit 400.FIG. 12 depicts a top view of thepersonal units 400 installed in an aircraft. - The floor space of each personal unit is, in some embodiments, partially defined by a unit cell, in particular where the unit cell provides storage space underneath the foot well, with the remainder being defined by the cabin floor. In other embodiments, the floor space may be defined entirely by a unit cell, or a combination of unit cells. In yet other embodiments, the floor space is defined entirely by the cabin floor.
- The personal units are attached to tracks that run under or along the floor, parallel to the respective column axis. The footrest defining a lower boundary of a foot space has an extendable part extendable towards the backward end of the personal unit, which may assist in forming the bed. The extension may take the form of a flip-up extension or a drawer that slides from under the footrest. A seat pan extension may also be analogously formed to extend forward from the seat pan.
- The seats may convert into beds according to EP1417113, which is incorporated by reference herein, in which a backrest of the seat is folded forward, with the opposite side of the backrest used to form part of the bed.
- The angle between the longitudinal axis and the respective column axis is about approximately 30 degrees. In some embodiments, the angle is between approximately 20 to approximately 55 degrees.
- The personal units in the first column are offset from the respective personal units in the second column, in a direction parallel to the column axes, by an amount which is between approximately 0 and approximately 1 times the distance between adjacent personal units in the same direction, for example about approximately 0.5 times or between approximately 0.2 to approximately 0.8 times.
- The preceding detailed description is merely some examples and embodiments of the present disclosure and that numerous changes to the disclose embodiments can be made in accordance with the disclosure herein without departing from its spirit or scope. The preceding description, therefore, is not meant to limit the scope of the disclosure but to provide sufficient disclosure to one of ordinary skill in the art to practice the invention with undue burden.
