Abstract
An aircraft passenger seating arrangement comprises a seat 3 having a seat pan 3b and a seat back 3a, the seat being able to adopt a first, substantially upright sitting position (Fig. 5a) and a second, sleeping position (Fig. 5d) in which the seat back and seat pan are substantially horizontal, the arrangement further including a side surface 5 arranged to form part of a substantially flat, horizontal sleeping surface alongside the seat, and an end surface 7 moveable between a first position to form part of the substantially flat, horizontal sleeping surface forward of the seat and a second position to serve as a footstool. The seat may comprise an auxiliary surface (3c, Fig. 5d) positionable between the seat pan and the end surface in the sleeping position. Also disclosed is a seat comprising a headrest moveable by an inflatable actuator (Fig. 6), and a cabin sidewall comprising an internal window panel (Figs 9-11).
Description
Aircraft Passenger Seat The present invention relates to an aircraft passenger seat, particularly but not exclusively to an aircraft sleeper seat convertible into a substantially flat bed, and to a cabin sidewall suitable for use with such a seat.
Background to the Invention
Examples of prior art aircraft sleeper seats are disclosed in the applicant's patent publications WO-A-96/ 18537, WO-A-00/2 1831 and WO-A-07/072045, embodiments of which include the British Airways First and/or Club World seats. These seats can be converted into a flat, horizontal bed, and have enjoyed great commercial success.
However, there is intense competition to provide ever-greater comfort and space for aircraft passengers.
Passenger seats for aircraft are subject to stringent design constraints, many of which are not applicable to seats for other vehicle types. One problem is the need to meet the relevant safety standards for aircraft passenger seats, such as the I 6g test that requires seats to survive deceleration of 1 6g in a takeoff/landing position. Another problem is the need to minimize the weight of the seat, since carrying extra weight on an aircraft increases fuel consumption and therefore monetary and environmental cost. Hence, the seat must be both strong and light.
Another problem relates to the use of space. Any given aircraft has a maximum area for passenger seating, which must be used in the most space-efficient manner possible so as to maximize the seating area and legroom available to each passenger, while allowing unimpeded exit from the seat. It is also important for cost reasons to fit as many passenger seats as possible in the available area.
Another problem relates to the level of comfort of the seat. Aircraft passenger seats may be used for day flights, in which the passenger will want to work, eat and/or relax, and night flights during which the passenger will want to sleep. Preferably, an aircraft passenger seat should be able to adopt comfortable positions for all of these activities, yet also be able to meet the relevant safety standards in a takeoff/landing position.
Another problem relates to the psychological and/or social needs of aircraft passengers, who may desire privacy while working, eating or sleeping, or may wish to interact with a travelling companion.
Patent publication EP-A-1 116654 (BE Aerospace) discloses an aircraft passenger sleeper seat that can adopt fully upright, semi-reclined or lounge and fully reclined or sleep positions. The seat includes an ottoman that functions as a foot or leg support, and has a top cushion and a pivoting legrest cushion.
The applicant's earlier unpublished application PCT/GBO7/001 796 discloses an aircraft passenger seating arrangement comprising a seat having a seat pan and a seat back, the seat being able to adopt a first, substantially upright sitting position and a second, sleeping position in which the seat back and seat pan are substantially horizontal, the arrangement further including a side surface arranged to form part of a substantially flat, horizontal sleeping surface alongside the seat. An end surface is arranged to form part of a substantially fiat, horizontal sleeping surface forward of the seat. The end surface may be substantially continuous with the side surface and may be integrated therewith. The end surface may comprise a secondary seat and may be stowable. There may be provided a movable footstool stowable under the end surface.
Statement of the Invention
According to one aspect of the present invention, there is provided an aircraft passenger seating arrangement comprising a seat having a seat pan and a seat back, the seat being able to adopt a first, substantially upright sitting position and a second, sleeping position in which the seat back and seat pan are substantially horizontal, the arrangement further including a side surface arranged to form part of a substantially flat, horizontal sleeping surface substantially alongside the seat in the sleeping position, and an end surface moveable between a first position to form part of the substantially flat, horizontal sleeping surface forward of the seat and a second position to serve as a footstool when the seat is in the sitting position.
According to another aspect of the present invention, there is provided an aircraft passenger seat having a seat back including a substantially rigid adjustable headrest portion for supporting the head of a passenger and an inflatable actuator arranged to move the headrest portion relative to the seat back.
According to another aspect of the present invention, there is provided a cabin sidewall for a commercial passenger aircraft, comprising an internal window panel arranged to cover two external windows, and means for blocking an external window adjacent the two external windows.

Detailed Description of the Embodiments
Terminology In describing the embodiments, horizontal' and vertical' are defined with reference to the floor of the passenger seating area of the aircraft. As in well known in the art, the angle of the floor relative to the gravitational horizontal is determined by the pitch of the aircraft, which is about 150 during takeoff and landing, and about 30 in level flight.
When describing an individual seat, forward' and rearward' are defined with reference to the direction in which the passenger faces when seated. Outboard' refers to a position adjacent a cabin wall of the aircraft cabin, while inboard' refers to a position away from the cabin wall.
Seating Arrangement As shown in Figures 1 to 4b, an aircraft passenger seating arrangement in an embodiment of the present invention comprises the following main components: a seat 3 comprising seat back 3a and seat pan 3b, a housing or shell 4 partially surrounding the seat 3, a side surface 5 extending forward and alongside of the seat 3, a footstool 7 positioned forward of the seat and a credenza' or cabinet 6. The main components may be constructed as separate components and installed together in an aircraft to form the seating arrangement. Not all of the main components are essential to all aspects of the present invention.
An armrest 8 is provided at either side of the seat pan 3b. One or both of the armrests 8 may be lowered or retracted so that they are substantially level with, and preferably continuous with the side surface 5. The side surface 5 is preferably fixed with respect to the floor, and its height is not adjustable by the passenger. A headrest portion of the seat back 3a comprises a moveable headrest 9, as described in detail below.
The cabinet 6 is positioned to one side of the seat 3, adjacent the side surface 5. The cabinet 6 may house one or more passenger facilities, such as a stowable table, a light, controls for reclining the seat 3 and/or operating an in-flight entertainment (WE) system. The cabinet 6 has a top surface for use as an occasional table or cocktail tray.
The shell 4 extends behind and to at least one side, and preferably to both sides of the seat 3. For inboard seats, the shell 4 includes a privacy screen; for example, it may conceal the seated passenger, at least partially, from surrounding seated passengers.
Preferably, the seat back 3a remains substantially within the shell 4 as it reclines; for example, the seat back 3a does not project significantly, or at all, above the shell.
Preferably, the shell 4 conceals and/or hinders passenger access to a reclining mechanism for the seat 3. The shell 4 may also provide passenger storage and/or facilities, such as an IFE screen stowable flush with the shell 4.
Seat Reclining Positions The seating arrangement includes a seat reclining mechanism which allows the seat 3 to be positioned in at least a sitting and a sleeping position, and preferably in each of the following four positions, as shown in Figures 5a to Sd: a) upright sitting position: the seat back 3a is fully upright, at 10200 to the vertical (13° in this example), and the seat pan is tilted rearwardly by 2-10° (4° in this example) to provide a comfortable position for working or eating.
b) taxi, takeoff and landing (TTOL) position: the seat back 3a is slightly reclined, at 20-30° to the vertical (28° in this example), and the seat pan 3b is tilted rearward by 10200 (15° in this example), to provide a secure and comfortable position. Preferably, the seat 3 meets the I 6g test criteria in this position.
c) reclined position: the seat back 3a is reclined, at 30-70° to the vertical (56° in this example), and the seat pan 3b is tilted rearward by 10-20° (17° in this example), to provide a comfortable position for resting and using IFE.
d) Bed position: the seat back 3a and seat pan 3b are substantially horizontal, at 0- 10° to the horizontal (3° in this example so as to be gravitationally horizontal in level flight), and form a substantially continuous and/or flat surface suitable for sleeping on.
An auxiliary surface 3c is pivotally attached to the forward end of the seat pan 3b. In positions a) and b), the auxiliary surface 3c is stowed under the seat pan 3b, and is preferably substantially vertical. In position c), the auxiliary surface 3c is driven by the seat reclining mechanism to an intermediate position at an angle of approximately 30° to the vertical. In position d), the auxiliary surface 3c is driven by the seat reclining mechanism to a substantially horizontal position, so that the seat back 3a, seat pan 3b, auxiliary surface 3c and footstool 7 form a substantially flat, horizontal and continuous sleeping surface. In position d), the side surface 5 is substantially coplanar and/or continuous with the seat pan 3b and auxiliary surface 3c so as to form a sleeping surface that is wider than the seat pan 3b. One or both of the armrests 8 may be driven by the scat mechanism to retract in position d), so as to form a flat continuous surface with the seat back 3a and/or the side surface 5.
Hence, the seat arrangement may provide a sleeping surface that is considerably wider than the seat pan along the majority of the length of the sleeping surface. Moreover, the major axis of the sleeping surface is in the longitudinal direction of the seat 3, so the passenger need not greatly adjust his or her orientation when moving to the sleeping position d) from another position. The side surface is elongate, with a major axis substantially parallel to the longitudinal direction of the seat 3, so that it does not greatly increase the overall width of the seating arrangement.
Preferably, the seat reclining mechanism and/or controls enable the seat 3 to be reclined continuously between the positions a) to d) and maintained in any of those positions or 1 5 in intermediate positions therebetween. Alternatively, the seat reclining mechanism and/or controls may restrict the positions in which the seat 3 may be maintained.
However, it is preferable that a continuous transition between at least positions b) and c) is possible.
As can be seen from Figures 5a to 5d, the seat mechanism is operable to lift the seat pan 3b to a substantially horizontal position level with the side surface 5 as the seat approaches the sleeping position d). Specific mechanisms for achieving combined pivoting and lifting of seat pans are known per se in the art.
The seat mechanism further acts to drive the auxiliary surface 3c from its stowed position in seat positions a) to c) to its substantially horizontal position in seat position d). Mechanisms for driving legrests pivotally attached to seat pans are known per se in the art and may be used to drive the auxiliary surface 3c, with suitable modifications.
Headrest As shown in Figure 6, the headrest 9 is pivotable forward relative to the seat back 3a so as to give additional support to the passenger's head. The angle of pivot is adjustable by the passenger, up to a maximum angle which may be 30° or more. The pivoting of the headrest 9 is driven by an inflatable chamber 11 located between the pivotable headrest 9 and a headrest support 10, the latter being fixed relative to the seat back 3a. The inflatable chamber 11 is inflated by an air pump controlled by the passenger. As the air chamber inflates, it applies pressure between the headrest support 10 and the headrest, thus pivoting the headrest 9 forwards. This provides a convenient mechanism for controlling to angle of the headrest 9, since the pump may be concealed in the space under the seat 3, and may be connected to the inflatable chamber 11 by a tube. Also, the headrest 9 provides firmer support than would be provided if the passenger's head were to rest directly against the inflatable chamber 11 or the inflatable chamber I I were to be covered with flexible material.
Footstool As shown in Figures 8a and 8b, the footstool 7 is moveable between a footstool position, which is low and positioned towards the seat 3, and a bed-end position which is high, positioned away from the seat 3 and substantially flush with the side surface S as shown particularly in Figure 7. The mechanism for moving the footstool 7 between the footstool position and the bed-end position may comprise a parallelogram linkage, as indicated by dotted lines in Figure 8b. Preferably, the footstool 7 may be locked in at least the bed-end position, from which it is releasable by a passenger-actuated latch.
In the bed-end position, the footstool 7 may be used as a buddy seat' i.e. a secondary seat facing the seat 3, allowing a companion to sit opposite the occupant of the seat 3 when in position a) or b). When the seat 3 is in position d), the footstool 7 forms an end portion of the bed, thus extending the length of the bed provided by the seat 3, while the side surface 5 extends the width of the end of the bed. Hence, a substantially flat and continuous horizontal bed surface is provided by the seat back 3a, seat pan 3b, armrests 8, side surface 5, auxiliary surface 3c and footstool 7.
In the footstool position, the footstool 7 is positioned so as to conveniently provide a rest for the passenger's feet.
Cabin Sidewall As shown in Figures 9 to 11, the cabin sidewall comprises, for each individual seating arrangement, a window fascia panel 12 which frames and encapsulates two window apertures for each passenger. The cabin sidewall comprises a sidewall surface 13 which projects inwardly from the original sidewall 23 as provided by the aircraft manufacturer. A rectangular recess 14 is provided in the sidewall surface 13, within which the following components are housed: a window reveal 17, which provides a frame around the cabin windows 24a, 24b; a shade assembly 18, which provides a single vertically retractable shade 21 across both windows 24a, 24b; a shade mechanism 20 for driving the retraction and deployment of the shade 21; a strip light 22, for example comprising an array of LEDs, for illuminating the recess 14, and an internal window panel 25 which forms the internal surface of the window fascia panel 12. At its lower end, the sidewall surface 13 curves outwardly to join an unmodified cabin sidewall surface 15 and dado panel 16 and thereby forms a recess under the window fascia panel 12; this ensures that the sidewall surface 13 does not impinge on the passenger's lateral legroom.
The internal window panel 25 is preferably made from polycarbonate or PPSU (polyphenylsuiphone); the latter material is preferred, since it is heat resistant and meets the burning toxicity test requirements for commercial passenger aircraft, even when present in the quantities required for the size of the window panel 25. The window panel 25 may comprise a non-reflective and/or scratch-resistant coating. The window panel 25 may include an opaque border that obscures internal constructional features of the window fascia panel 12.
As shown in Figure 11, those windows 24c which are not aligned with the seating arrangement so as to provide two windows 24a, 24b per passenger, are blanked out by the sidewall surface 13; there may also be provided a light-tight plug between the sidewall surface 13 and the window 24c. Although this reduces the amount of natural light available to the cabin, it enhances the feeling of ownership that a passenger feels over the space occupied by his or her seating arrangement; the passenger does not need to share any part of that arrangement with another passenger.
Alternative Embodiments Alternative embodiments of the invention may be apparent from reading the above description. Such alternative embodiments may nevertheless fall within the scope of the present invention.
