Description

[0001] The present invention concerns aircraft cabins. More particularly, but not exclusively, this invention concerns an aircraft cabin comprising a seat unit having a foot well that is positioned beneath an item of furniture belonging to another seat unit. The invention also concerns a kit of parts for forming the aforementioned aircraft cabin.

[0002] Business class seating generally aims to provide aircraft passengers with maximum comfort and privacy. However, the design of aircraft passenger seat units for business class seating is constrained by the limited availability of space within an aircraft cabin. Increasing the packing density of seat units is highly desirable for airlines due to increased revenues that can result from the increased number of paying business class passengers that can be contained within a given aircraft cabin space.

[0003] WO2014049362A1 and WO2011 / 141134A1 both disclose examples of aircraft cabin arrangements in which seat units which are situated away from the cabin aisles are provided with aisle access paths that do not pass through any neighbouring seat units. A particular benefit of this type of configuration is that a passenger of a non-aisle seat unit is able to access the aisle without disturbing a passenger of the aisle seat unit.

[0004] Business class seats that are configurable to a lie-flat bed-mode configuration are desirable for medium range and long range missions. Wide-bodied aircraft have traditionally been used for such missions. However, narrow-bodied aircraft requiring a single-aisle cabin layout are now being used for medium range missions of up to approximately 5 hours as well. As such, high density business class cabin arrangements for narrow-bodied aircraft are desirable.

[0005] The present invention seeks to mitigate the above-mentioned problems. Alternatively or additionally, the present invention seeks to provide an improved aircraft cabin. SUMMARY OF THE INVENTION

[0006] The present invention provides, according to a first aspect, an aircraft cabin according to claim 1.

[0008] The aircraft cabin of the first aspect invention enables the packing density of seat units within the aircraft cabin to be increased by arranging the non-aisle seat units 19 03 26 and aisle seat units of a given pair of seat units to have overlapping footprints. Such an arrangement reduces unused dead space within the aircraft cabin. The footprints of the seat units overlap in an overlapping area which contains a foot well of one of the seat units and an item of furniture belonging to the another of the seat units.

[0009] Each seat unit of the first plurality may be situated directly adjacent to the aisle on an aisle-side of the seat units and directly adjacent to the first cabin wall on an opposite non-aisle-side of the seat units.

[0010] Each seat unit of the second plurality may be situated directly adjacent to the aisle on an aisle-side of the seat units and directly adjacent to the second cabin wall on an opposite non-aisle-side of the seat units.

[0011] The walls of the cabin may be substantially parallel with the longitudinal axis of the cabin. The non-aisle seat unit of each pair of seat units may be situated in front of the aisle seat unit of the pair. Alternatively, the aisle seat unit of each pair of seat units may be situated in front of the non-aisle seat unit of the pair. Each seat unit may comprise a seat configurable between an upright sitting position and a lie-flat bed mode configuration. Each seat may comprise a seat pan, back rest, a leg rest, and a head rest. Each seat unit may comprise only a single seat. Each seat unit may comprise a foot well. Each seat unit may be configured such that the leg rest of the seat extends into the foot well when in the seat is in the lie-flat configuration. Alternatively or additionally, a foot support surface may be contained within the foot well. A foot well of an aisle seat unit may be positioned between the seat of each non-aisle seat unit and the aisle. A foot well of a non-aisle seat unit may be positioned between the seat of each aisle seat unit and the first cabin wall.

[0012] The item of furniture may be one of an arm rest, a table surface, a cupboard, a storage area, a shelf or any other surface or item of furniture that can be used by a passenger of the seat unit in which the item of furniture is located. The aisle-side and non-aisle seat units of each pair of seat units may be at least partly formed by a shell. The shell may at least partially form the foot well of one or more of the seat units. The shell may at least partially provide the item of furniture of one or more of the seat units.

[0013] The aisle-side and non-aisle seat units of each pair of seat units may be at least partly formed by a shell. The shell may at least partially form the foot well of one or more of the seat units. The shell may at least partially provide the item of furniture of one or more of the seat units. 19 03 26

[0017] Preferably, for the first plurality of seat units, the aisle and non-aisle seat units are spaced apart with respect to one another along the length of the aircraft cabin such that the non-aisle seat unit of a given pair is provided with an aisle access path between the aisle seat unit of the pair and the aisle seat unit of an immediately adjacent pair. The immediately adjacent pair may be the pair immediately in front of the given pair or the pair immediately behind the given pair. The aisle access path of a given pair may be positioned between the aisle seat unit of the pair and the aisle seat unit of the pair located directly in front. The aisle access path of a given pair may be positioned between the aisle seat unit of the pair and the aisle seat unit of the pair located directly behind. An arrangement in which the non-aisle seat unit is provided with an aisle access path that does not pass through the neighbouring aisle seat unit is particularly beneficial because the non-aisle passenger can access aisle without disturbing a passenger of the neighbouring non-aisle seat units who may, for example, be asleep with their seat in the lie-flat bed mode configuration.

[0018] Preferably the aisle access path has a width of no more than 50 centimetres. The aisle access path may have a width of at least 20 centimetres. Preferably the aisle access path has a width of at least 25 centimetres. Advantageously the aisle access path of each pair is oriented at an access path angle of between 0 and 90 degrees with respect to a longitudinal axis of the aircraft cabin. Preferably the access path angle is between 10 and 80 degrees, more preferably between 50 and 65 degrees. The aisle access path may define an access path axis. The angle between the aisle path axis and longitudinal axis of the aircraft cabin may define the access path angle.

[0019] Each aisle seat of the first plurality of seat units faces towards the aisle and each non-aisle seat of the first plurality of seat units faces towards the first cabin wall. One of the factors determining the pitch of an aircraft seat unit is the length of the aircraft seat when in its longest configuration. This may be, for example, a lie flat configuration. Thus, when designing a seat unit, the pitch of a seat unit may be at a maximum where the seat faces in the direction of travel, substantially parallel to the longitudinal axis of the aircraft cabin. Where there is space available across the width of the cabin it can be beneficial to orient the seats at an angle with respect to a longitudinal axis of the aircraft cabin in order to reduce the pitch of the seat unit. As such, a cabin arrangement in which the seats are oriented at an angle to a longitudinal axis of the aircraft cabin can ensure 19 03 26 both the space available both along the length of the cabin and along the width of the cabin is efficiently used to improve seat unit packing density.

[0020] The aisle seat angle is greater than the non-aisle seat angle. Increasing the aisle seat angle allows for a wider aisle access path to be provided. The aisle seat angle can therefore be greater than the non-aisle seat angle in order to provide more space for an aisle access path. Preferably the aisle seat angle is at least 10 degrees.

[0023] One of the factors determining the pitch of an aircraft seat unit is the length of the aircraft seat when in its longest configuration. This may be, for example, when the seat is in a lie flat configuration. Thus, when designing a seat unit, the pitch of a seat unit may be at a maximum where the seat faces in the direction of travel, substantially parallel to the longitudinal axis of the aircraft cabin. It is well known to angle seats with respect to the longitudinal axis of an aircraft to reduce the overall pitch of a seat unit. However, angling the seats in this way increases the space used across the width of the cabin. This advantageous arrangement recognises that where there the cabin is arranged with a plurality of aisle and non-aisle seat units interposed, and where those seat units comprise seats that are angled to face away from one another in a herringbone-type manner, potentially unused space available across the width of the cabin can be used by arranging the seat units across the width of the cabin such that space directly behind a given seat unit along a seat unit axis is used by the seat unit that is positioned directly behind the given seat unit. Arranged as such, a seat unit axis, which is essentially a straight line drawn parallel to the longitudinal axis of the cabin, passes through each of the aisle and non-aisle seat units of each of the plurality of pairs of seat units. This optional feature therefore increases the packing efficiency of seat units within a cabin by improving use of space across the width of the cabin.

[0024] For each seat unit, the seat unit axis may intercept or pass through one or more of an item of furniture, and / or through a space behind the seat into which the seat reclines when in the lie-flat configuration.

[0025] Preferably each seat is configurable to a lie-flat configuration in which a back rest of the seat is reclined to form a substantially planar surface with a seat pan of the seat and the seat unit axis passes through the said seats when the seats are in the lie-flat configuration.

[0026] The aircraft cabin may comprise a 2-1 arrangement of seats across the width of the cabin wherein the second plurality of seat units comprises a column of single seat units located directly behind one another along the length of the aircraft cabin, the single seat units being situated directly adjacent the aisle on a first side of the seat unit and directly adjacent a cabin wall on a second, opposite side of the seat unit. Alternatively, the aircraft cabin may comprise a 2-2 arrangement of seats units across the width of the cabin wherein the second plurality of seat units is a plurality of pairs of seat units, each pair of seat units comprising a non-aisle seat unit that is situated directly adjacent the second cabin wall and an aisle seat unit that is situated directly adjacent the aisle.

[0027] Preferably the second plurality of seat units is arranged in substantially the same way as the first plurality of seat units. Advantageously, the first and second pluralities of seat units are symmetrically arranged about a longitudinal axis of the cabin. The second plurality of seat units may be a mirror image of the first plurality of seat units. The second plurality of seat units may be arranged in substantially the same way are the first plurality of seat units but the second plurality of seat units may be offset along the length of the aircraft cabin with respect to the first plurality of seat units. CXI 19 03 26

[0028] The present invention provides, according to a second aspect, a kit of parts suitable for forming an aircraft cabin according to any preceding claim.

[0029] It will of course be appreciated that features described in relation to one aspect of the present invention may be incorporated into other aspects of the present invention. For example, the kit of parts of the invention may incorporate any of the features described with reference to the aircraft cabin of the invention and vice versa. DESCRIPTION OF THE DRAWINGS

[0030] Embodiments of the present invention will now be described by way of example only with reference to the accompanying schematic drawings of which: Figure lisa plan view of an example aircraft cabin; Figure 2 is a plan view of a single pair of seat units of the aircraft cabin in isolation with the seats in an upright sitting configuration; Figure 3 is a plan view of the single pair of seat units in isolation with the seats in a lie-flat bed mode configuration; Figure 4 an enlarged view of the portion of Figure 1 that is contained within the box labelled D; Figure 5 is a plan view of an aircraft cabin according to an embodiment of the invention; and Figure 6 is a plan view of a single pair of seat units of the aircraft cabin of Figure 5 in isolation with the seats in an upright sitting configuration. DETAILED DESCRIPTION

[0031] A plan view of an example aircraft cabin 100 which is not an embodiment of the invention is shown in Figure 1. The aircraft cabin 100 is that of a narrow-body aircraft and therefore comprises a single aisle 101 that runs along the length of the cabin 100, substantially parallel to a longitudinal axis X of the aircraft cabin 100. A first plurality seat units 120 is positioned on a first side of the aisle 101 and a second plurality of seat units 140 is positioned on a second, opposite side of the aisle 101. As can be seen in Figure 1, the first plurality of seat units 120 and second plurality of seat units 140 are arranged symmetrically about the longitudinal axis X and are therefore substantially identical mirror images of one another. 19 03 26

[0032] The first plurality of seat units 120 comprises a plurality of pairs of seat units 121A, 121B, 121C situated behind one another along a seat unit axis SI that runs the length of the aircraft cabin 100, substantially parallel to the longitudinal axis X of the aircraft cabin 100. Similarly, the second plurality of seat units 140 comprises a plurality of pairs of seat units 141A, 141B, 141C situated behind one another along a seat unit axis S2 that runs the length of the aircraft cabin 100, substantially parallel to the longitudinal axis X of the aircraft cabin 100. Because each of the pairs of seat units 121 A, 121B, 121C, 141 A, 141B, 141C are arranged in substantially the same way, the arrangement of the pairs of seat units 121 A, 121B, 121C, 141 A, 141B, 141C will now be described with reference only to the single pair of seat units 121A that is depicted in isolation in Figure 2 and in Figure 3.

[0033] The pair of seat units 121A consists of an aisle seat unit 122A comprising an aisle seat 125A situated immediately adjacent the aisle 101 with direct access to the aisle 101, and a non-aisle seat unit 123A comprising a non-aisle seat 126A situated immediately adjacent the starboard wall 102 of the aircraft cabin 100 and spaced apart from the aisle 101. The aisle seat unit 122A and non-aisle seat unit 123 A of the pair 121A are spaced apart along the aircraft cabin 100 such that the non-aisle seat unit 123 A of the pair 121A is situated forwards of the aisle seat unit 122A. The aisle seat units 122A of adjacent pairs 121A are spaced apart along the cabin 100 to allow for an aisle access path 124A for each non-aisle seat unit 123 A to be provided in the space between the aisle seat unit 122A of the pair 121A and the aisle seat unit 122B of the pair of seat units 121B situated immediately in front of the seat units 121A. The aisle access path 124A has a width V of 25 centimetres and defines an access path axis W that is oriented at an angle 5 of 55 degrees to the longitudinal axis X of the aircraft cabin. A passenger of the non-aisle seat unit 123A can thereby access the aisle 101 via the aisle access path 124A without having to disturb passengers who might be situated in a neighbouring aisle seat unit 122A, 122B.

[0034] Each of the seat units 122A, 123 A comprises a privacy wall 127A positioned in front of and to the rear of its respective seat 125 A, 126A to enclose its respective seat 125A, 126A at its front and at its rear. The privacy walls 127A are each formed by a shell and separate each seat unit 122A, 123 A from the seat units situated immediately in front and immediately behind. Arranged as such, the front privacy wall 127A of a given seat unit forms the rear privacy wall 127A of the seat unit situated immediately 19 03 26 in front and vice versa. Each seat 125A, 126A comprises a seat pan 1251 A, 1261 A, a back rest 1252A, 1262A, and a leg rest 1253A, 1263A and is configurable between an upright sitting configuration, as depicted in Figure 2 and a lie-flat bed mode configuration, as depicted in Figure 3, in which the back rest is reclined to be substantially level with the seat pan and in which the leg rest is moved upwardly into a position in which it is substantially level with the seat pan.

[0035] As can be seen in Figure 2, the aisle seat unit 122A comprises a table surface 131A positioned at a side of the aisle seat 125A, between the aisle seat 125A and the first cabin wall 102 and the non-aisle seat unit 123A comprises a table surface 132A positioned at a side of the non-aisle seat 126A, between the non-aisle seat 126A and the aisle 101. The table surfaces 131 A, 132A are configured for use by the passengers of the respective seat units 122A, 123 A. Furthermore, each of the seat units 122A, 123A comprises a foot well 129A, 130A that is positioned in front of its respective seat 125A, 126A. As can be seen in Figure 3, when the seats 125A and 126A are configured to the lie-flat bed mode configuration, the leg rest 1253A, 1263A of each seat 125A, 126A extends into its respective foot well 129A, 130A. The foot well 130A, table surface 132A, and privacy wall 127A that separates the aisle seat unit 122A of a given pair and non-aisle seat unit 123A of that pair are formed by a single shell 135A and the foot well 131 A, table surface 132B, and privacy wall 127A that separates the non-aisle seat unit 123 A of the pair of seat units 121A from and aisle seat unit 122B of the pair of seat units 121B situated immediately in front of the pair 121A are formed by a single shell 136A.

[0036] The pitch P of a seat unit is the distance along the longitudinal axis X of the aircraft cabin 100 between a given point on a seat unit and the corresponding point the immediately adjacent seat unit situated to the front or to the rear. As an example, the pitch P of the seat units is illustrated in Figure 4 between the aisle seat unit 122A of the pair 121A and the aisle seat unit 122C of the pair of seat units 122C that is situated immediately behind the pair 122A. For a business class seating arrangement such as that described here, the pitch of a seat unit is dictated at least in part by the length of the seat when the seat is in the lie-flat bed mode configuration. Both the aisle seats 125A and the non-aisle seats 126A are oriented at an angle to the longitudinal axis X of the cabin 100 in order to reduce the pitch of their respective seat units 122A, 123A and to make efficient use of the space available across the width of the cabin 100. The 19 03 26 non-aisle seats 126A face towards the immediately adjacent cabin wall 102 in a direction defining a non-aisle seat axis Y which is at an angle of a = 10 degrees to the longitudinal axis X of the aircraft cabin 100. The aisle seats 125 A face towards the aisle 101 in a direction defining an aisle seat axis Z which is at an angle of P = 12.5 degrees to the longitudinal axis X of the aircraft cabin 100. The angle between the non-aisle seat axis Y and the aisle seat axis Z is therefore 22.5 degrees. Such an arrangement results in a seat unit pitch P of 201 centimetres (79 inches). The aisle seat angle P is greater than the non-aisle seat angle a in this case in order to provide adequate width V for the aisle access path 124A.

[0037] With the aisle and non-aisle seats 125A, 126A angled to face away from one another, the aisle and non-aisle seat units 122A, 123 A can be arranged across the width of the cabin 100 such that they both overlap the seat unit axis SI. As can be seen in Figures 2 and 3, for both the aisle and non-aisle seat units 122A, 123A, the seat unit axis SI passes through the seat 125A, 126A, table surface 131 A, 132A, and through the space 137A, 138A behind the seat 125A, 126A into which the seat 125A, 126A reclines when in the lie-flat configuration. Arranged as such, potentially dead space behind an aisle or non-aisle seat unit 122A, 123 A is utilised by the respective neighbouring non-aisle or aisle seat 123A, 122A. Such a configuration therefore increases the packing efficiency of seat units within the cabin 100.

[0038] The packing efficiency of the seat units within the cabin 100 is also increased by the aisle and non-aisle seat units 122A, 123A being arranged with overlapping footprints that overlap in overlapping areas in which space is used by both an aisle seat unit 122A and a non-aisle seat unit 123 A. Each pair of seat units 121A is arranged such that the foot well 129A of the aisle seat unit 122A of a given pair of seat units 121A is situated directly below the table surface 132A of the non-aisle seat unit 123A of the given pair 121A. The foot well 129A of the aisle seat unit 122A and table surface 132A of the non-aisle seat unit 123A of a given pair are therefore positioned together in an overlapping area 133A. Similarly, the foot well 130A of the non-aisle seat unit 123A of a given pair of seat units 121A is situated directly below the table surface 13 IB of the aisle seat unit 122B of the pair of seat units 121B situated immediately in front of the given pair 121 A. The foot well 130A of the non-aisle seat unit 123A of a given pair of seat units 121A and the table surface 13 IB of the pair of seat units 121B situated 19 03 26 immediately in front of the given pair 121A are therefore positioned together in an overlapping area 134A.

[0039] An aircraft cabin 200 according to an embodiment of the invention is shown in Figure 5 and Figure 6 with seat unit axes SI’ and S2’. Many features of the aircraft cabin 200 are similar to those of the example aircraft cabin 100 described above and, where present, features in common with the example aircraft cabin 100 have been numbered with corresponding reference numerals but having the prefix “2” instead of “1”. For example, the example aircraft cabin 100 has a plurality of pairs of seat units 121 whereas the aircraft cabin 200 which is an embodiment of the invention has a plurality of pairs of seat units 221. As with the description of the example aircraft cabin 100, the cabin arrangement will be described with reference to a single pair of seat units 221A only.

[0040] In the aircraft cabin 200 of the presently described embodiment of the invention the non-aisle seat axis Y’ is at an angle of a’ = 2 degrees to the longitudinal axis X’ of the aircraft cabin and the aisle seat axis Z’ which is at an angle of P’ = 18 degrees to the longitudinal axis X’ of the aircraft cabin 200, while the pitch P’ of 201 centimetres has been maintained. In this arrangement there is an overlapping area 234A between the foot well 230A of the non-aisle seat unit 226A and a storage cupboard 239A of the aisle seat unit 225A situated in front of the non-aisle seat unit 226A. However, the foot well 229A of the aisle seat unit 225A does not form part of an overlapping area with the non-aisle seat unit 226B situated immediately in front. The increased aisle seat angle P’ has moved the foot well 229A of the aisle seat unit 225A into a position in which it is too far away from the non-aisle seat to be positioned beneath an item of furniture that is easily accessible from the non-aisle seat. As with the example cabin 100 described above, the non-aisle overlapping area 234A contains the foot well 230A of the non-aisle seat unit 226A. However, in this embodiment of the invention a storage cupboard 239A is located in the aisle seat unit 225A above the foot well 230A of the non-aisle seat unit 226A in place of a table surface 131 A.

[0041] Whilst the present invention has been described and illustrated with reference to a particular embodiment, it will be appreciated by those of ordinary skill in the art that the invention lends itself to many different variations not specifically illustrated herein. By way of example only, certain possible variations will now be described.

[0042] While the above-described embodiment of the invention corresponds to a 2-2 cabin arrangement having pairs of seat units arranged symmetrically either side of the cabin aisle, another embodiment of the invention corresponds to a 2-1 (or 1-2) arrangement in which a plurality of pairs of seat units are arranged along a first side of an aisle and a plurality of single seat units are arranged along a second, opposite side of the aisle.

[0043] Where in the foregoing description, integers or elements are mentioned which have known, obvious or foreseeable equivalents, then such equivalents are herein incorporated as if individually set forth. Reference should be made to the claims for determining the true scope of the present invention, which should be construed so as to encompass any such equivalents. It will also be appreciated by the reader that integers or features of the invention that are described as preferable, advantageous, convenient or the like are optional and do not limit the scope of the independent claims. Moreover, it is to be understood that such optional integers or features, whilst of possible benefit in some embodiments of the invention, may not be desirable, and may therefore be absent, in other embodiments. 19 03 26
