Abstract

A SEATING SUITE FOR A PREMIUM AIRCRAFT CABIN A seating suite for a passenger aircraft.The suite comprises two end walls, spaced apart in a longitudinal direction to define opposing ends of the suite; a chaise-longue having a back rest and a base portion; and a seat spaced apart from the chaise-longue.The chaise-longue is convertiblebetween a lounging configuration in which the back rest and the base portion are arranged with respect to each other such that a passenger can sit in the chaise-longue, and a bed configuration in which the chaise-longue forms a lie-flat bed on which the passenger may sleep.

Description

A SEATING SUITE FOR A PREMIUM AIRCRAFT CABIN Technical Field The present invention relates to aircraft seating, and more specifically to a seating suite for a passenger aircraft, and a cabin comprising a plurality of those seating suites.
The seating suites of the present invention are
especially, but not necessarily exclusively, suitable for use in a premium (first class) aircraft cabin.
Background of the Invention
There is an increasing desire for innovative seating arrangements in premium aircraft cabins, which seek to offer exceptional comfort and space for passengers, yet are also space-efficient within the aircraft.
The idea of providing a seating suite, comprising one or more sidewalls and a separate bed and seating surfaces is known. For example, WO2014/155354 (Etihad Airways) describes an arrangement comprising a suite having a pair of end walls enclosing a seat assembly and an ottoman. The ottoman extends transversely, across the width of the suite. The ottoman is useable as a footrest for the passenger in the seat, or as a temporary seat for an additional passenger during flight. The ottoman is also convertible into a lie-flat configuration by sliding the ottoman seat cushion forward and rotating the ottoman seat back until it forms a horizontal surface with the seat cushion. This lie-flat bed extends transversely across the width of the suite.
US 9,187,178 (B/E Aerospace) discloses a suite comprising spaced-apart end walls enclosing a first seating assembly and a second seating assembly. The first seating assembly is configured as the main seat for reclining and relaxing, whereas the second seat is a fixed chair facing a table, and is upright for use during dining. The first seating assembly folds away to enable a bed (in the form of a flexible
membrane) to be deployed. The bed is supported over the seat pan of the dining chair.
Other arrangements such as some of Lufthansa' s First Class products, provide a permanently deployed bed, alongside a passenger seat.
The present invention seeks to provide an improved seating suite.
Summary of the Invention According to a first aspect of the invention, there is provided a seating suite for a passenger aircraft, the suite comprising: two end walls, spaced apart in a longitudinal direction to define opposing ends of the suite; a lounging seat having a back rest proximal to one of the end walls, and a base portion extending towards the other end wall; and a seat spaced apart from the lounging seat; wherein the lounging seat is convertible between (i) a lounging
configuration in which the back rest and the base portion are arranged with respect to each other such that a passenger can sit in the lounging seat, and (ii) a bed configuration in which the lounging seat forms a lie-flat bed on which the passenger may sleep.
By providing a lounging seat (convertible into a flat¬ bed) in combination with a separate seat, the suite of the present invention provides numerous different seating/resting possibilities for the passenger. In the lounging configuration, the back rest and the base portion may be arranged with respect to each other such that a passenger can sit in the lounging seat in a semi-recumbent position. In the bed configuration, the lie-flat bed is preferably arranged to allow the passenger to sleep in a fully recumbent position.
In the lounging configuration, the base portion is preferably arranged to support a passenger sitting on said base portion. The base portion preferably comprises a
cushioned surface for receiving the passenger. The base portion may be arranged to support a passenger' s thighs and buttocks. The lounging seat may comprise a base portion that is longer than a typical seat pan. For example the base portion may be more than 20 inches long. The length of the base portion may be such that when the lounging seat is in the lounging configuration, it is configured to receive the passenger resting on the lounging seat, with their back against the back rest, with both the upper and lower parts of their leg supported on the supporting portion (for example when outstretched) . The upper part of the passenger's leg may be above the knee (for example the upper part is the thigh) . The lower part of the passenger's leg may be below the knee.
The base portion may be more than 30 inches long. The base portion may be more than 40 inches long. The base portion may be over 44 inches long. The base portion may be less than 50 inches long. The base portion may have a width of over 22 inches. The base portion may have a width of over 25 inches. The base portion may have a width of 28 inches or more. The base portion may have a width of 30 inches or more.
In preferred embodiments of the invention, the lounging seat is a chaise-longue. A chaise-longue has been found to be an especially effective way of providing a seat with lounging functionality. In the description below, features are described with reference to the chaise longue but it will be appreciated that those features may be equally applicable to a lounging seat more generally.
The default configuration of the chaise-longue may be the lounging configuration. The chaise-longue may be certified for taxi, take-off and landing (TTOL) when in the lounging configuration. The chaise-longue is preferably not
convertible into a more upright configuration, such as a seating configuration. The base portion is preferably a single element; it is preferably not foldable into a smaller seat pan or alike.
The chaise-longue is preferably orientated along the longitudinal direction of the suite. It will be appreciated that the chaise-longue need only extend generally in a
direction along the length of the suite. It need not
necessarily be perpendicular to the end walls. It need not necessarily be parallel to the longitudinal direction of the suite .
The back rest is proximal to one of the end walls. The back rest need not, however, necessarily be in contact with the end wall.
When the chaise-longue is in the lounging configuration, the back rest may be at an angle to the base portion. The back rest may be orientated at a sufficient angle to support a passenger's back when the passenger's legs are on the base portion. The back rest may be at an obtuse angle to the base portion. The base portion may be substantially horizontal.
In the bed configuration the chaise-longue forms a flat¬ bed. The flat-bed may form a substantially flat surface for a bed. The length of the flat-bed may be 75 inches or more.
The length of the flat-bed may be 80 inches or more. In some embodiments of the invention, the chaise-longue may be
convertible into the bed configuration by the back rest and the base portion being moved (for example folded with respect to each other) to create a bed surface. In the bed
configuration the back rest and the base portion may be co- planar .
The suite comprises a seat. In some embodiments of the invention, the seat is not convertible to a flat-bed. The seat may comprise a seat pan and a seat back. The seat pan and seat back of the seat may be fixed relative to each other.
The seat may recline. For example, the seat may be
rotatable (preferably by only a moderate amount, such as less than 45 degrees) about a recline axis.
The seat may be rotatable about a swivel axis. The swivel axis may be an upright axis. The seat may be rotatable about a swivel axis such that the seat can swivel between a taxi, take-off and landing (TTOL) orientation, and a swivelled orientation. The seat may be lockable in the TTOL
orientation. The seat is preferably certified for take-off, taxi and landing in the TTOL position. The seat may be rotatable to a multiplicity of swivelled orientations. For example, the seat may be freely rotatable about the swivel axis (unless locked in the TTOL position) .
The location of the seat is preferably fixed. Thus, whilst the seat may be rotatable about recline and/or swivel axes, the location of the seat preferably remains the same. The swivel axis is preferably fixed.
The seat may be positioned relative to the chaise-longue such that, when the chaise-longue is in the lounging
configuration, part of the base portion is accessible to act as a foot-rest for a passenger in the seat. Such an
arrangement has been found to be beneficial because it enables the chaise-longue to have dual-functionality, enabling an increase in the number of seating/resting positions for the passenger without increasing the number of pieces of furniture .
The base portion of the chaise-longue may be generally rectangular shaped (in planform view) . However, the corner of the base portion proximal to the seat may be chamfered. The chamfer may be such that it facilitates egress between the seat and the chaise-longue, for example by widening the gap between the seat and the base portion. Embodiments of the present invention recognise that chamfering the corner is especially beneficial as it facilitates egress without unduly impacting on the useable area of the base portion.
The corner may be chamfered such that it creates a foot- rest surface facing the seat. The foot-rest surface may be configured to receive the soles of the feet of the passenger in the seat. The foot-rest surface may form an oblique surface extending through the depth of the base portion. The foot-rest surface may extend at an angle to the upper surface of the base portion.
The suite may comprise a table. The table may be located in a default location in the corner of the suite. The default location may be a stowed location. The table may be moveable (for example extendable) towards the seat such that the table, when moved, is accessible from the seat. The seat may be rotatable about a swivel axis, to a dining orientation, such that a passenger in the seat can access the table for dining.
The table may be moveable (for example slideable) , from the default location, along the length of the suite. The table may be moveable such that a passenger in the chaise-longue can access the table (for example, for dining) when the chaise- longue is in the lounging configuration.
The suite of the first aspect of the invention is for use in a passenger aircraft. The suite may be for use in a premium class cabin of a passenger aircraft. The suite may be located adjacent an aisle of the aircraft. The aisle may run alongside the suite, along the longitudinal direction of the suite. The suite may be for use with a plurality of other, preferably substantially identical suites, in the aircraft. The suites may be separated across the width of the aircraft by one or more aisles.
The end walls of the suite preferably define a partially enclosed space for use by the passenger. The end walls are preferably solid, but need not necessarily be so (for example they may be any structure (such as a perforated or slotted structure) that creates the feeling of an enclosed space for the passenger) . The end walls may be substantially parallel. One of the end walls may extend wider than the other, such that the footprint of the suite is generally trapezoidal with one end wider than the other. The seat may be located in the wider end of the suite. The back rest of the chaise-longue may be located in the narrower end of the suite.
In some embodiments, an end wall may be a stand-alone structure. In some embodiments, an end wall may be defined by internal structure (such as a bulkhead) in the cabin.
According to another aspect of the invention, there is provided an aircraft cabin comprising a plurality, and
preferably a multiplicity, of the seating suites described herein, the suites being spaced apart across the width of the cabin. The suites may be spaced apart along a row. The suites may be staggered along the row. The suites may be in¬ line across the row.
The multiplicity of suites may comprise two outer suites each located against an opposing the sidewall of the cabin. The cabin may comprise one or more suites located between the outer suites (spread in a direction across the width of the cabin) . The one or more suites may comprise at least one central suite located between the outer suites. In embodiments in which each suite is generally trapezoidal with one end wider than the other, the side wall of the aircraft may form one side of the trapezoid, for the outer suites .
The orientation of the suites may alternate across the width of the cabin from the sidewall to the centreline of the cabin .
The outer suites may be orientated in the same, first, direction. The suite (s) inward of, but adjacent to, each the outer suite may be orientated in a second, opposite,
direction. The suites may be arranged in a 1-X-l layout.
Thus, the suite (s) inward of, but adjacent to, each the outer suite may be one or more central suites. The central suite (s) may be orientated in the second, opposite, direction. In embodiments having a 1-1-1 layout, there is only a single central suite. In embodiments having a 1-2-1 layout, there are two central suites. In such an embodiment having 2 central suites, the central suites may face the same
direction. The central suites may be located either side of the centre line of the aircraft. The two central suites may be substantially symmetrical across the longitudinal axis of the cabin. The outer suites may be substantially symmetrical across the longitudinal axis of the cabin.
The outer suites may be separated from the other seats in the row (for example from the at least one central suite) by respective aisles. The aisles may be angled in opposing directions away from the longitudinal axis of the cabin. Such an arrangement tends to occur when the outer and central suites are generally trapezoidal and orientated in opposing directions. Such an arrangement is beneficial because it enables an efficient use of the cabin width because the widest parts of the outer suites are adjacent the narrowest parts of the central suite (s) and vice versa. It will be appreciated that any features described with reference to one aspect of the invention are equally
applicable to any other aspect of the invention, and vice versa. For example, features described with reference to the suite of the first aspect, may be present in any of the suites in the cabin of the second aspect (and vice versa) .

Detailed Description
Figure 1 is a plan view of a premium class cabin 1 according to a first embodiment of the invention. The premium class cabin 1 is located at the front of a large passenger aircraft (not shown) . The cabin 1 comprises three suites 3a-c arranged in a row across the width of the cabin, with two outer suites 3a/3b and one central suite 3c (i.e. a 1-1-1 layout) . In the cabin of Figure 1, there is only one row of suites, but in other embodiments of the invention (not shown) , a cabin may comprise a plurality of such rows.
The cabin 1 of Figure 1 also includes a rest-room area 5 positioned fore of the suites 3a-c. However, the content and layout of the area 5 is not directly related to the invention and will not be discussed further herein.
Each of the suites 3a-c in Figure 1 has essentially the same key features, namely: two end walls 7 spaced-apart along the length of the suite, a chaise-longue 9 extending along the suite and a swivel seat 11 fixed at the opposite end of the suite to the chaise-longue 9. These features will now be described with reference to Figures 2a and 2b which show one of the outer suites 3b in close up.
Referring first to Figure 2a, the suite 3b comprises substantially straight end walls 7, 7', extending parallel to each other and away from the aircraft side wall 13. The fore- most wall 7 is shorter in length than the rear-most wall 7' such that the suite 3b forms a generally trapezoidal shape.
At the narrower end of the suite 3b, and orientated along the length of the suite (parallel to the aircraft sidewall 13) is the chaise-longue 9. The chaise-longue 9 comprises a back rest 15 proximal the end wall 7, and a base portion 17
extending towards the other end wall 7' . The chaise-longue 9 is shown in Figure 2a in a lounging configuration in which the back rest 15 forms an obtuse angle to a horizontal base portion 17 (most clearly seen in Figure 3) . The base portion 17 is relatively long (43.5 inches) enabling a passenger to lounge on the chaise-longue with the upper and lower parts of their legs supported.
The chaise-longue 9 is certified for TTOL in this
configuration.
The base portion 17 is rectangular in planform except that the corner 17' nearest the seat (that seat being
discussed in more detail below) is chamfered. The chamfer is in an oblique plane into the depth of the base portion such that it creates a flat, foot support surface 19, angled to face the seat 11. This surface 19 is best shown in Figure 3, which is a perspective view of the suite from behind the seat 11.
The suite 3b also comprises a seat 11 positioned at the opposite end to the chaise-longue 9, but located in sufficient proximity to the chaise-longue 9 such that a passenger in the seat 11 is able to place their heels on the corner 17' of the chaise-longue when seated in the seat 11. The seat is located within the trapezoidal footprint of the suite.
The seat 11 is fixed in location but can swivel about a vertical swivel axis (not labelled in the Figures but
extending out of the page in Figures 2a-b) . The seat 11 is lockable to fix it in the TTOL orientation (shown in Figure 2a) , but releasable from that orientation to swivel either outwardly towards the aisle 21, or inwardly towards the dining table 23 (discussed in more detail below) . In the TTOL position, the seat 11 faces the foot surface 19 created by the chamfered corner 17' of the base portion 17. This enables the passenger to not only extend their legs onto the upper surface of the corner of the base portion 17' of the chaise-longue 9, but it also means that the passenger can rest their feet on the chamfered foot support surface 19 in an intermediate, xtucked' position with their legs bent and knees upwards.
The seat 11 is arranged to swivel to face a 31 inch-wide table 23 (as shown in the upper suite of Figure 1, and in Figure 2a) . The table 23 is arranged to extend towards the seat 11 such that the passenger can use this as a desk, or dining table, when sat in the seat 11.
As well as being extendable towards the seat 11, the table 23 is also slideably mounted on a rail 25 to move along the length of the suite 3b, towards the chaise-longue 9. The table 23 can thus be brought towards the passenger such that they can access the table 23 whilst on the chaise-longue 9 in either the lounging configuration or the bed configuration.
Referring back now to the chaise-longue 9 more generally, the chaise-longue 9 is convertible between the lounging configuration shown in Figure 2a, to the flat-bed
configuration in Figure 2b. To convert the chaise-longue to the flat-bed configuration, the back rest 15 is moved down, and the leg support portion 17 slides forwards. An ancillary support surface 29 behind the back rest 15 is exposed, by virtue of the back rest 15 having moved down, and all three elements combine to provide an 80 inch long flat bed. As shown in Figure 2b, the chamfered corner 17', enables this long bed to be accommodated in the suite without fouling the seat 11. As will be appreciated from the above-description of the first embodiment of the invention, the combination, and the layout, of the chaise-longue 9 and the seat 11 enables a passenger in each suite 3a-c to adopt numerous resting
positions, all within the tight space constraint of an
aircraft seating suite.
Referring back to Figure 1, each of the suites in the first embodiment are generally trapezoidal. The outer suites 3a, 3b are orientated with the chaise-longue 9 facing
rearwardly, but the central suite 3c is orientated in the opposite direction with the chaise-longue 9 facing forwardly. As a result, the aisles 21 extending either side of the central suite 3c (and adjacent the respective outer suites 3a, 3b) are angled outwardly from the centre-line 31 of the cabin. Having this alternating orientation of suites, is an
especially efficient use of the width of the aircraft cabin because the wide part of the central suite 3c is adjacent the narrow parts of the outer suites 3a, 3b, and vice versa.
Figure 4 shows a cabin of a second embodiment of the invention. Features in the second embodiment of the invention that correspond to similar features in the first embodiment of the invention, are shown with the same reference numerals as in the first embodiment, but with the addition of the prefix λ1' (or λ10' where appropriate) .
Each suite 103a-d has a similar content and layout to that in the first embodiment except that each suite is of slightly different proportions (especially a narrower width) to enable a 1-2-1 layout of suites in which there are two central suites located side-by side.
The outer suites 103a, 103b comprise a chaise-longue 109 having slightly reduced width (28 inches) but it still
provides an 80 inch flat-bed in the bed configuration (see Figure 5c) . Figures 5a to 5c show a plan view of the upper outer suite 103a. Figures 5a and 5b show the chaise-longue 109 in the lounging configuration, and Figure 5c shows the chaise-longue in the bed configuration. As most clearly shown in Figure 5c, the chamfered corner 117' enables the long, 80 inch, bed length to be provided despite the inclusion of the swivel chair 111 in the suite 103a. The table 123 is also of bi-fold construction such that it can more easily be stowed in the available space, yet folded out when required.
The unfolding of the table 123 is shown when comparing Figures 5a and 5b. In Figure 5a, the table is showed in a folded configuration having a depth of 9.5 inches. It is folded outward to a depth of 18 inches, and the seat 111 can be swivelled around to face the table 123 to facilitate dining .
The primary difference between the first and second embodiment is the central pair of suites 103c, 103d, to which reference is now made with reference to Figures 7a and 7b. The central pair 103c, 103d both face rearwardly and are symmetrical about the centre line 131 of the cabin. The suites 103c, 103d share a mutual divider 133 that is in the form of a collapsible wall. If the passengers in the central suites 103c, 103d are travelling together (or otherwise become amorous) and wish to share a bed, the divider may be lowered (see Figure 7a) . If the passengers prefer some privacy, the divider 133 may be fully or partially raised, as is shown in Figure 7b.
Finally, referring back to Figure 4, it can be seen that the orientation of the suites alternates from the outer suites 103a, 103b, towards the centre line 131 of the aircraft. The orientations are the opposite of those in the first
embodiment, so the aisles are directed inwardly (when looking forward) , but the principle of using the width of the cabin efficiently still applies. Whilst the present invention has been described and illustrated with reference to particular embodiments, 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. 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.
