Abstract
A passenger seating arrangement for an aircraft cabin is disclosed. A plurality of seat units 10 each comprise at least a first reclining seat 12 and a second reclining seat 14. The seat units are located in a column adjacent to a longitudinal aisle 20 of the aircraft cabin. The first reclining seat and the second reclining seat of the seat units are configured to have substantially similar plan view contour and side-by-side alignment when similarly reclined. The seat units are angled to the aisle to provide a direct access from the aisle to the first and second reclining seats of the seat units. The seat units in the column are arranged in a staggered herringbone configuration relative to the aisle. The seats may be able to convert into a double bed configuration. Two successive seat units can be normal relative to each other. Four seat units can be formed in an X shaped configuration to provide a group seating area.
Description
Seating system for an aircraft This disclosure generally relates to aircraft seating systems. More particularly, passenger specifically arranged passenger seat units for an aircraft and method for operating the seat units are disclosed.
Seats in a passenger aircraft are typically arranged in longitudinal columns along an aisle. An aircraft can comprise one or two aisles. The number of aisles typically but not necessarily depends on the width of the aircraft body. A passenger aircraft can be divided into cabins, and include different cabin types, commonly called "classes". Passenger aircrafts can be divided into economy and business class seating areas, or cabins. Other classes such as first class and premium economy may also be provided. The cabin types can be named differently by different aircraft operators. For clarity, in the following the cabins are divided between economy and premium class cabins, unless considered necessary to use more specific categorization of the classes.
An important difference between the cabin types is the level of passenger comfort. The cabin designs and features providing the differentiation can be significantly different in different classes. For example, in the economy class seats are commonly arranged in straight longitudinal columns of adjacent seats in rows with shared armrests, small if any tray like tables, relatively shallow backrest reclines Of any) and short pitch between the seat in the rows. In the higher, i.e., premium classes comfort is a much more important design factor. Typically, a premium class cabin has wider seats with deeper recline, even what is commonly called the lie flat capability and overall feeling of more space and comfort. Additional comfort increasing features can also be provided, such as footrests, fixed and/or bigger tables, storage space, monitors and so on.
Deeper recline, greater pitch between the seats and wider seats takes more space. This limits the number of seats. Auxiliary comfort increasing equipment such as fixed tables, TV monitors and personal storage space further eats into the limited space within the aircraft. Various seating designs have therefore been proposed to optimise the use of the limited space. A common solution is to angle, e.g., the business class and premium economy seats relative to next seats and the aisle and stagger the seats in the column so that more deep reclining seats can be provided in the available space compared to seats that are lined in straight rows normal to the aisle.
Further improved use of the space while still offering premium class comfort may be desirable. This can be especially desirable on single aisle aircraft cabins. The herein described examples aim to address one or more of issues relating to premium class type seating systems.
According to an aspect there is provided a passenger seating arrangement for an aircraft cabin, comprising: a plurality of seat units each comprising at least a first reclining seat and a second reclining seat and located in a column adjacent to a longitudinal aisle of the aircraft cabin, wherein the first reclining seat and the second reclining seat of the seat units are configured to have substantially similar plan view contour and side-by-side alignment when similarly reclined, the seat units are angled to the aisle to provide a direct access from the aisle to the first and second reclining seats of the seat units, and the seat units in the column are arranged in a staggered herringbone configuration relative to the aisle.
According to an aspect there is provided a passenger seating arrangement for an aircraft cabin, comprising a plurality of seat units each comprising at least a first reclining seat and a second reclining seat and located adjacent to a longitudinal aisle of the aircraft cabin, wherein the first reclining seat and the second reclining seat of the seat units are configured to have substantially similar plan view contour and side-by-side alignment when similarly reclined, the seat units are angled to the aisle to provide a access from the aisle to the first and second reclining seats of the seat units, and the seat units are in a configuration where two successive seat units in a column are about normal relative to each other.
According to an aspect there is provided a passenger seating arrangement for an aircraft cabin, comprising four seat units located adjacent to a longitudinal aisle of the aircraft cabin, wherein two seat units are in a first column and two seat unit are in a second column, each seat unit comprises at least one reclining seat, the seat units are angled to the aisle to provide access from the aisle to the at least one reclining seat of the seat units, and the four seat units are arranged in about a X-shaped configuration to provide a group seating area.
According to yet another aspect there is provided a method for a passenger seating arrangement in an aircraft cabin wherein a plurality of seat units is located in a column adjacent to a longitudinal aisle of the aircraft cabin and comprise seat units arranged into the aircraft cabin as described herein, the method comprising moving a first reclining passenger seat and an adjacent second reclining passenger seat relative to each other between an upright position and a reclined position while maintaining a side-by-side alignment between the first and second seats when similarly reclined.
In accordance with a more detailed aspect the reclined position of the first and second reclining seats provides a lie flat configuration. The first and second reclining seats may be arranged to provide a double bed style configuration in the lie flat position.
The first reclining seat and the second reclining seat of the seat units can be independently moveable relative to each other between an upright position and a fully reclined position. The plan view of the second reclining seat in the fully reclined position may be arranged to be a mirror image of the first reclining seat in the fully reclined position.
The second reclining seat of the seat units can be located closer to the aisle than the first reclining seat, the difference in the distance to the aisle being defined by the angle of the seat unit to the aisle.
The first and second reclining seats can be arranged in a substantially parallel configuration in the seat unit. Alternatively, the first and second passenger seats may be modestly angled relative to each other in the seat unit. The angle between the seats can be up to 25 degrees.
The angle between the seat units and the aisle measured as an angle between the centre line between the two reclining seats and the centre line of the longitudinal aisle can be within the range of 30-50 degrees.
Seat units in a column of staggered seat units comprising the first and second reclining seats may be nestled.
A separate egress may be provided for each of the first and second seats of the angled seat units for the direct access to the aisle. The seat units may comprise doors in the separate egresses for to the first and second reclining seats.
A shared egress for the first and second reclining seats of the seat units may be provided for access to the aisle.
Shape of at least one of corner of the seats may be formed in dependence of the positioning of the seat units relative to the cabin walls and/or the aisle. Two successive seat units in a column can be arranged into about normal relative to each other. The seat units can form a group seating area. Moveable 10 divider may be provided between the two successive seat units. Direct access may be provided between the two successive seat units without need to enter the aisle.
The invention will become more fully understood from the detailed description of certain examples and the accompanying drawings, in which: FIGURE 1 is a top plan view of an example of a single aisle cabin with double seat units arranged according to the herein disclosed principles; FIGURES 2A, 2B and 20 show views of an exemplifying seats in different positions; FIGURE 3 is a top plan view of an example for a seating system of a two aisle cabin; FIGURES 4 and 5 are schematic presentations of further examples; FIGURES 6 to 10 are schematic presentations of examples of group seating arrangements; FIGURES 11A, 11B, 12A, 12B, and 120 are schematic presentations of further examples of double seat units; FIGURES 13A and 13B are schematic presentations of door mechanisms for double seat units; FIGURES 14A and 14B are schematic presentations of possible angular relations of the seats of a seat unit; and FIGURE 15 is a flow chart of a method according to an example.
The following description gives an exemplifying description of some possibilities to practise the invention. Although the specification may refer to "an", "one", or "some" examples or embodiment(s) in several locations of the text, this does not necessarily mean that each reference is made to the same example of embodiment(s), or that a particular feature only applies to a single example or embodiment. Single features of different examples and embodiments may also be combined to provide other embodiments.
The following describes with reference to the appended drawings certain detailed examples for specific arrangements of seat units that can be assembled into an aircraft cabin. A seat unit comprising at least two aligned passenger seats is also described. The herein described principles and features can optimise use of floor space on an aircraft. Certain embodiments can increase passenger comport, especially for passengers travelling together or in groups.
Figure 1 shows a schematic plan view of a passenger seating system for a cabin 1 of a single aisle 20 aircraft in accordance with an example. The seating system comprises a plurality of seat units 10 located in right hand column 22 and left column 21 on either side of the single longitudinal aisle 20 extending through the cabin 1. In this example the cabin 1 has six double seat units 10 providing twelve passenger seats. The seat units 10 each comprise a first reclining seat 12 and an adjacent second reclining seat 14. The two reclining seats 12, 14 are moveable between an upright position and a reclined position. In the Figure 1 example all seats in column 21 to the left of the aisle 20 are in upright position. The seats of the last or back seat unit 10' in column 22 to the right of the aisle 20 are in a fully reclined position.
A stowable privacy divider 11 can be provided between the first and second seats 12, 14 of a seat unit. The divider can be fully stowable, e.g., can be fully lowered between the seats, or partially stowable. Some of the auxiliary furniture such as table 23 and ottoman 28 may be provided in association with the privacy divider 11.
The seat units 10 are separated by walls 25. These can be of relatively fixed construction. Auxiliary furniture such as tables and storage places can be provided in association with the separating walls 25. For example, passengers on the "window seats" 12 can be provided with personal space / table 13. Passengers on the "aisle seats" 14 can use personal space / table 15. Passengers on both seats can have additional storage places 16 and 17 at the head ends of their seats.
Ottomans 29 for the "window seat" passengers can also be provided in connection with the separating structure 25. Further furniture such as monitors 26 and tray tables 27 that can be moved away can be provided as a part of the structure defining the seat unit.
The reclining of seat can be arranged to provide a lie flat configuration, as shown by seat unit 10' in Figure 1. The two seats of the seating unit can be reclined independently from each other over a reclining range between the extreme reclining positions of upright and lie flat. The concept of reclining passenger seat and different possibilities for the mechanisms enabling the movement are well known and therefore are not explained in detail here.
Figure 1 shows that the first passenger seat 12 and the second passenger seat 14 of the double seat units 10 are configured to have substantially similar plan view contour in the reclined and upright positions. This can apply to the seats over the entire reclining range. Examples for different detail of the contour such that the available space can be efficiently and/or flexibly used will be explained later in this
description.
The first passenger seat 12 and the second passenger seat 14 are arranged into a side-by-side alignment with each other in all positions, i.e., when similarly reclined or upright. Examples of the seats in different positions are shown by the side and top plan views of a double seat unit 10 in Figures 2A -2C. Figure 2A shows both seats 12, 14 in upright position. Figure 2B shows both seats in an intermediate or "lazy Z" position. Figure 20 shows both seats 12, 14 in full flat position. In the example of Fig. 2C flight compensation has been applied to the seats and thus the seats are not full horizontal. The compensation can be, e.g., 1 to 4 degrees. As illustrated by the top plan and side views, the seats 12, 14 of the seat unit 10 are in complete alignment when similarly reclined.
The aligned first and second seats 12, 14 of the seat units 10 can also be arranged to provide double bed style configuration when reclined into the lie flat position. This may be desired by couples or family members flying together. The divider between the seats can be removed, for example lowered down between the seats entirely or partially. In the latter alternative a feet end part of the divider may be fixed. A head end part may be arranged to slide or otherwise be stowed away next to the feet end part.
The alignment of the seats is facilitated by staggering the seat units 10 instead of staggering the individual seats 12, 14 in the columns. The staggering of the seat units 10 provides a herringbone configuration of the seat units 10 relative to the aisle 20 whereas the seats of the seat units are not in herringbone formation.
The first passenger seat 12 of the seat unit 10 is located further from the aisle than the second passenger seat 14. The difference in the distance from the aisle to the set depends on the angle of the seat unit. The angling of the staggered seat units 10 to the aisle 20 is indicate by the dashed line 24, the first seat 12 and the second seat 14 being correspondingly angled to the aisle 20.
Passenger seats 12, 14 are provided with direct access to the aisle via respective egresses 18 and 19. The term direct access refers herein to an access arrangement where inconvenience of so called stepover on next passenger can be avoided. The egresses can be provided per individual seat of a seat unit. Examples of individual egresses are shown in, e.g., Figures 1, 2 and 3.
A shared egress can also be provided in certain types of seat units. An example of this is shown in Figure 12C. A mix of individual and shared egresses can be provided in a column and/or cabin.
The angle is designed such that it enables direct access paths 18, 19 to the aisle from both seats. According to an example, measured between the centre line 24 of the seats and the centre line 30 of the aisle, the angle can be in the range of to 50 degrees. According to a specific example the angle is 38 degrees.
The alignment of the seats 12, 14 within the staggered seat units 10 enables more efficient use of the space. A reason for this is that the last seat unit 10' in the column 22 can be positioned closer to the back end of the cabin 1 than would be the case if the seats would be arranged in a herringbone as that would need to be taken further back. The alignment of the seats can also be desirable by passengers travelling together.
Figure 1 plan view also illustrates an example how the contours of the feet rests at the at the feet ends and of the back rests at the head ends of the seats 12, 14 can be shaped to efficiently use the available space in the cabin 1. In this regard a refence can also be made to the arrangement of the seat units 10 and contours of the seats in Figures 6 and 7. At Is some corners of the seat element can be shaped based on the angle on which the element faces cabin structures such as the side and middle wall, the aisle, and the dividers.
The space can be used even more efficient if the seat units are arranged in a nestled configuration, an example of which is shown in Figure11.
The seat can be configured to have pitch (the distance between similar point on adjacent seat units) in the range 40 to 70 Inches / 101 to 178 cm. In accordance with a specific example the pitch is about 60 inches / 152 cm per the two seats of a seat unit. Width w of each passenger seat, can be in the range of seat pan widths from 17 to 40 inches / 43 to 101 cm.
Figures 1 and 2C illustrate how the plan view of the second passenger seat 14 in the reclined position can be a mirror image of the first passenger seat 12. This can be advantageous in optimising the use of space in the corner areas of the seat unit 10. The contours of the seats can be designed to further optimise and/or facilitate more flexible use of the available space in the cabin, for example as shown in the Figs. 1, 4, 6 and 7. The mirroring provides further advantage in allowing manufacture of one design, even if in a mirror image, for all the seats. Figure 3 shows an example of a twin aisle cabin comprising three columns of staggered seats units 10. In general, the seat units can be arranged in each column as described with reference to the single aisle cabin.
Figure 3 shows further the possibility to have different seat units, in the example single seat units 30, in a column. This can be advantageous, e.g., at the end of a column.
Figures 4 and 5 shows other examples where at least one of the seat units in a column is different from the two seat units 10. In these examples the first rows are occupied by first class seats 40.
Figures 6 to 10 shows examples where a group or family section is provided by an arrangement of seat units into about normal angles to each other. It is noted that the about normal is not intended to be limited to exactly 90 degree but rather refers to angles like the X-shaped configurations shown in the figures.
Figure 6 shows a plan view of the seats of the seat units 10 in upright position. Figure 7 shows a plan view of the seat units in double bed configuration. In Figure 6 and 7 four double seat units 10 are arranged in a four-point star shaped, i.e., X-shaped configuration over two of the columns to provide a group section 60 at the front end of the cabin on a single aisle aircraft. The furniture in the middle can be arranged to be on a relatively low level so that the members of the group have a good visibility of each other. In the bed configuration seats 72, 73 reclined in lie flat position may share the egress 74. Need for this depends on the furniture and the way the dividers 75 and 76 are designed. An additional divider 77 can be provided between the double bed seat units 10. All dividers 75, 76 and 77 can be stowable. For example, in X-shaped configuration of four flat beds in a family zone the centre screen or divider 77 between two double beds can fold away, and there can be a flexible arrangement of three dividers that can be folded away. Moveable divider 77 between the double seat units in a column makes it possible to move from one double bed unit to the another without accessing the main aisle in a family or group zone.
The group section can be separated from the rest of the cabin by a curtain 62. The remainder of the cabin can comprise seats units 10 in the herringbone configuration as described above. The location of the X-shaped group of four seat units can be anywhere in the cabin. Also, more than one such group can be provided. It is also possible to have just two double seat units angled about normal to each other in one column.
Figure 8 shows an example where four double seat units are grouped into about star shaped relation to each other on a twin aisle aircraft. Figures 9 and 10 show examples where first-class seat units are grouped into about X-shaped relation to each other on a single aisle aircraft and a two aisle aircraft, respectively. Communications between members of a group can be improved by a system of headsets connected to each other to a form a network of communication 25 devices for group communications. The communications may be provided through the wired audio system of the aircraft. The network may also be provided wirelessly based on appropriate wireless standards and/or close range radio protocols. For example, BluetoothTM or some WiFi based short range radio system may be used for the group communications. This can provide enhanced comfort and experience for a family or another group in the group zone. Other group interaction features are also possible. For example, the furniture can be arranged to enable member to dine together.

Instead of fully reclining seats, i.e., lie flat seats it is possible to use staggered seat units in herringbone configuration comprising only partially reclining seats. Such configuration can be used for example for what is commonly called as Premium Economy class. Figure 11A shows a plan view of an example of a basic arrangement of such double seat units 80 in a single aisle cabin where the partially reclining seats 82 and 84 are in the upright position. Figure 11 B shows the seats of two seats units 80 in the right column in reclined position. The staggering facilitates direct access for both seats 82 and 84 to the aisle 86.
Figures 11A and B also shows an example of the nestled arrangement of the seat units. The amount of nestling is indicated in Figure 11A by the distance N between the dashed lines. A passenger occupying seat 82 can use the space underneath the slightly partially overlapping reclined seat 84. As shown in Figure 11B, even when reclined there is not that much overlap and seat 84 in the front does not extend too much into the space of the passenger on the seat 82 behind.
The restricted recline prevents the seat back of seat 84 from landing too close to the seat pan of seat 82. Accepting some nestling also allows for more flexibility in designing the cabin layout and placing of auxiliary equipment.
Figure 11 B also shows, in dashed lines in front and back of the last seat unit in the right column, how the seat pan can move forward, for example about 3 inches / 8 cm and as the back seat reclines.
Figures 12A -120 show examples for additional features of the seat units of Figure 11. In the Fig. 11A plan view of one column of seats units 80 comprising furniture such as side tables 83 and 85. As shown, there is sufficient space for reasonably sized side tables for both seats of the seat unit without blocking the direct access from the window seat 82 to the aisle 90.
Figure 12B shows a plan view of seat units 80 in a column where privacy dividers 92 are provided between seats 82 and 84 and separation dividers 94 are provided between the seat units. Each seat 82 and 84 has its own egress 93 and 95 for direct access to the aisle 90. The dividers 92 between the seats are at least in part moveable so that at least a part thereof can be stowed away to enable interaction and privacy as desired. Ottomans 86 and 87 are also provided for seats 82 and 84, respectively. Ottomans 86 are provided in connection with the privacy Ii divider elements 92. Ottomans 87 are provided in connection with the separation divider elements 92.
Figure 12C shows a variation of the divider arrangement where the seats of the seat units are separated by dividers 96 and the seat units are separated by more substantial separation dividers 97 than in Figure 11B. A common egress 98 is provided for the passengers in a seat unit with separation divider 97 between the seat units for the direct access to the aisle. Ottomans 88 and 89 are also provided for the seats 82 and 84, respectively. In this example both ottomans 88 and 89 are provided in connection with the separation divider elements 97.
Figures 13A and B illustrate in plan views examples of door mechanisms than can be provided in an access path to a passenger seat.
Figure 13A shows stages of closing the doors from left to right. On the left is a seat unit 10 where parts of a door mechanism 130 are stowed away. On the right hand seat unit the doors are fully deployed and the seats 12 and 14 enclosed into their own compartments. The door mechanism 130 comprises two door units 132 and 134. Part 132 is stowed in connection with the divider between the seats. Door part 134 is stowed in connection with the partition between the seat units. Part 132 swivels out of the divider to close egress 18. Part 134 slides from the side of the partition to close egress 19.
Figure 13B shows an example of a door mechanisms 135 where doors 136 and 138 for both egresses are stowed in connection with the divider 11 between the seats of the seat unit 10. The left seat unit has both doors 136 and 138 in stowed position. The right seat unit has both doors 136 and 138 slid into their deployed position. The sliding movement is indicated by the respective arrows.
In the above explained Figures the first and second passenger seats of a double seat unit are arranged substantially parallel to each other. It is also possible to have a double seat unit with seats that are slightly angled relative to each other. Figure 14A shows a schematic example of a modestly angled arrangement of seats 12 and 14 of seat units 10 separated by dividers 25. In this example the head ends are slightly separated from each other. Figure 14B shows an example where seats 12 and 14 of seat units 10 separated by dividers 25 are angled such that there is a gap at the foot rest ends. Stowable privacy divider 11 can extend about in the middle of the widening divisions. The angle between the centre lines of seats (denoted by the dashed lines) can be, for example up to 25 degrees in both examples.
Figure 15 is a flowchart for operating a seat unit as described herein. In the method a first reclining seat and an adjacent second reclining seat are moved at 100 relative to each other between an upright position and a reclined position while maintaining a side-by-side alignment between the first and second seats when similarly reclined. As explained above, the seat units and not the seats are in herringbone configuration. In 102 a double bed configuration can be provided when the first and the second seats are fully reclined.
The foregoing description provides by way of exemplary and non-limiting examples a full and informative description of exemplary embodiments of the invention. While certain aspects of the invention may be illustrated and described as schematic pictorial representation and flow charts, it is well understood that these blocks, systems, techniques and methods described herein may be implemented in various manners. Therefore various modifications and adaptations may become apparent to those skilled in the relevant arts in view of the foregoing description, when read in conjunction with the accompanying drawings and the appended claims. All such and similar modifications of the teachings of this invention will still fall within the spirit and scope of this invention.
