DETAILED DESCRIPTION

(2) Note that, in the Figures, structural and/or functional elements common to the different embodiments can bear the same reference numerals. Thus, unless stated otherwise, such elements have identical structural, dimensional and physical properties.

(3) In the rest of the description, the terms forward facing and aft facing define an orientation of the seats inside the aircraft cabin, meaning that a forward facing element faces the aircraft cockpit and an aft facing element faces in the opposite direction. The aircraft's direction of travel corresponds to direction D in the Figures. The forward part of the cabin is located at the cockpit end while the aft part of the cabin is located at the opposite end. Furthermore, the terms starboard and port are understood to have the common meaning that would be given to these terms by a person located inside the cabin and looking towards the front of the cabin in direction D.

(4) FIGS. 2a, 3a, 4a, 4b, 4c, 5a and 5b show an arrangement of an aircraft cabin 10 comprising at least one cabin attendant seat, called a high-comfort seat 11. As shown in FIGS. 1a, 1b and 1c, this high-comfort seat 11 preferably comprises an extendable seat bottom 12, a back 13 and a leg-rest 14, which can be provided with a foot-rest 15 that can be extended relative to the leg-rest 14.

(5) The seat 11 has kinematics that allow it to move between a stowed position in which the seat bottom 12 is folded against the seat back 13 to leave the area around the seat clear, as shown in FIG. 1a, a sitting position complying with safety regulations during aircraft taxiing, take-off and landing phases (known as the Taxi, Take-Off, Landing or TTL position), as shown in FIG. 1b, and at least one rest position in which the back 13 is inclined relative to the vertical and the leg-rest 14 supports the user's legs.

(6) The seat 11 can for example assume eight separate rest positions in which the relative angles of inclination of the different elements are different. The back 13 can be inclined by up to 45 degrees relative to the vertical. The seat 11 can be maneuvered by means of a handle to pass from one position to the other. Advantageously, the seat returns to the stowed position in an assisted manner.

(7) According to the invention, the high-comfort seat 11 is connected to a furniture unit 18. The seat 11 can fit into in a space 21 provided within the furniture unit 18 when the seat is in the rest position. The furniture unit is chosen from one of the following units: a galley module 24, a sanitary module 25, a storage module, or any other module suited to the application.

(8) Note that a galley module 24 is a furniture unit chiefly comprising trolleys 28, storage spaces and equipment to enable food to be cooked or heated up. One important characteristic of the galley module 24 is the number of storage trolleys 28 or half-trollies 28 that it can contain, because the airline companies need to have a certain number of trolleys that depends on the capacity of the aircraft.

(9) The sanitary module 25 specifically comprises toilets, a washbasin and a bin. Advantageously, the high-comfort seat 11 is physically separated from the passenger-dedicated area so as to be located in an area of the cabin 10 in which noise and light intensity are limited.

(10) There now follows a description, with reference to FIGS. 2 to 5, of the incorporation of the high-comfort seat 11 inside a single-aisle aircraft cabin, in other words with a single aisle bearing reference numeral 31. Clearly, the invention can also be implemented for twin-aisle cabins. In the Figures, the X axis corresponds to the longitudinal axis of elongation of the aircraft.

(11) As shown in FIG. 2a, in the case of an installation at the forward end of the cabin 10, the high-comfort seat 11 is fixed to a wall of a sanitary module 25.

(12) The furniture unit 18 incorporates two foot-rests 32 on its rear face for the adjacent passenger seats 33. Furthermore, a standard cabin attendant seat 36 is located between two storage compartments 37. Such a standard seat 36 is capable of assuming a stowed position and a sitting position, but does not have a rest position, as does the high-comfort seat 11. The standard seat 36 is positioned opposite the high-comfort seat 11. As a variation, the seats 11 and 36 can be offset relative to one another in a transverse direction perpendicular to the X axis.

(13) As can be seen in FIG. 2b, the high-comfort seat 11 extends at least partially into the space 21 of the furniture unit 18 delimited by the two walls facing the storage compartments 37 when the high-comfort seat 11 is in the rest position and the standard seat 36 is in the stowed position. The two cabin attendant seats 11 and 36 that face each other can be used simultaneously in the sitting position.

(14) The furniture unit 18 also comprises a retractable partition 40 extending along the aisle to ensure that the person occupying the high-comfort seat 11 has a direct view, in other words an unobstructed view of the aisles and cabin 10 when seated. According to regulations, the cabin attendant's direct view of the passengers allows him/her to check that the latter are safe. This direct view must cover at least 50% of each passenger class.

(15) Furthermore, a curtain 41, represented by a dotted line in FIG. 2a, can be drawn between the sanitary module 25 and the furniture unit 18 on the aisle side 31. This curtain 41 allows the high-comfort seat 11 to be isolated during rest phases.

(16) Such a configuration allows the number of passenger seats to remain unchanged while keeping a sufficient number of cabin attendant seats that can be used in the seated position.

(17) According to a variation, the furniture unit 18 has no standard cabin attendant seat 36 and incorporates a foot-rest independent of the high-comfort seat 11. It will also be possible to fill the spaces located around the foot-rest located in the furniture unit 18 with additional storage areas.

(18) FIG. 3a shows a second possible arrangement in the case of an installation of the seat 11 at the forward end of the cabin 10. According to this arrangement 10, a standard cabin attendant seat 36 is fixed to a sanitary module 25. This standard seat 36 can be single or double, in other words can comprise one or two seat bottoms 12 to accommodate two people.

(19) Moreover, the furniture unit 18 comprises two foot-rests 32 for the adjacent passenger seats, and one high-comfort seat 11 facing forward. As can be seen in FIG. 3b, two storage compartments 37 are provided on either side of the high-comfort seat 11. In other words, the high-comfort seat 11 is located in the space 21 between the two storage compartments 37, which limits the overall dimensions of the unit.

(20) The high-comfort seat 11 is positioned opposite the standard cabin attendant seat 36. The high-comfort seat can thus assume a rest position when the standard seat 36 is in the stowed position. As a variation, the seats 11 and 36 can be offset relative to one another in a transverse direction perpendicular to the X axis.

(21) The furniture unit 18 also comprises a retractable partition 40 extending along the aisle 31 to ensure that a person occupying the standard seat has a direct view of the aisles and cabin in the sitting position. Furthermore, a curtain 41, represented by a dotted line in FIG. 3a, can be drawn between the sanitary module 25 and the furniture unit 18 on the aisle side 31. This curtain 41 allows the high-comfort seat 11 to be isolated during rest phases.

(22) As shown in FIG. 4a, in the case of an installation in the middle of the cabin, a rest module 44 provides a separation between business class 45 and economy class 46. This module 44 comprises a forward partition 49 and an aft partition 50 to ensure the isolation of the module 44 relative to the sound and light environment of the cabin.

(23) Moreover, two high-comfort seats 11 are positioned side by side in the space 21 delimited by the partitions 49 and 50. These seats 11 are represented as facing aft but, as a variation, can face forward.

(24) Also, preferably a curtain or a movable partition 53 is provided, ensuring separation from the aisle 31 of the cabin 10, as well as a curtain or movable partition 54 ensuring separation between the two high-comfort seats 11.

(25) This configuration dictates, however, that 12 passenger seats must be eliminated from the middle of the cabin and six must be recovered at the end of the cabin by relocating two sanitary modules 25 opposite the rest module 44. This configuration is particularly suitable when two or more high-comfort seats 11 are required since no modification of the aft galley module 24 is necessary.

(26) In the embodiment shown in FIG. 4b, a rest module 44 ensures the separation between business class 45 and economy class 46. This rest module 44 comprises a forward partition 49 and an aft partition 50 to ensure isolation of the module 44 relative to the sound and light environment of the cabin 10.

(27) Inside the space 21 delimited by the partitions 49, 50, a high-comfort seat 11 is mounted facing aft on the fuselage side 57, and a sanitary module 25 is mounted on the aisle side 31. In this case, two rest modules 44 are used, positioned inside the cabin 10 symmetrically to the X axis.

(28) Such a configuration requires that six passenger seats are eliminated per module in the middle of the cabin and, if necessary three are recovered at the end of the cabin.

(29) In the embodiment shown in FIG. 4c, the starboard sanitary module 25 is replaced by a galley module 24. As a variation, the high-comfort seat 11 can be associated with a storage compartment or a dispenser of drinks and food products.

(30) As shown in FIG. 5a, in the case of an installation at the aft end of the cabin 10, a high-comfort seat 11 facing aft and located near an aft door 60 can extend at least partially into a space 21 arranged in a part of a galley module 24.

(31) For this purpose, the space 21 can be obtained by placing, for example, two half-trolleys 28 in spaces adapted to receive full trolleys 28, the difference between the volume occupied by the half-trolleys 28 and the space available defining a free volume enabling at least part of the high-comfort seat 11 to be received when the latter is in the rest position. The galley module 24 can for example comprise five trolleys 28 and two half-trolleys 28.

(32) In the embodiment shown in FIG. 5b, a hybrid module located at the aft end of the cabin 10 comprises a starboard part 61 incorporating a galley module 24 and a port part 62 incorporating two high-comfort seats 11 separated from one another by a partition 63. As a variation, the partition 63 can be replaced by a curtain.

(33) Such a configuration requires two sanitary modules 25 eliminated at the aft end of the cabin to be relocated in the middle of the cabin 10, for example to ensure the separation between two areas of the cabin, for example between business class 45 and economy class 46.

(34) Clearly, the invention is not limited by the embodiments previously described and provided purely by way of example. It encompasses different modifications, alternative forms and other variations that a person skilled in the art of the present invention can envisage and, in particular, all of the combinations of the different operating modes described above, can be taken separately or in combination.
