Multi-layered Sleeping Compartment

Abstract

A multi-layered sleeping compartment for an aircraft is provided to allow passengers to recline and sleep more comfortably. The multi-layered compartment accommodates multiple sleeping pods positioned on either side of an entrance, with the sleeping compartments generally aligned with the longitudinal axis of the aircraft. Furthermore, the pods may be reserved for session times during the aircraft's normal flight.

Description

[Technical field]

[0001] The present invention relates to a multi-layer sleep compartment, and more particularly to a multi-layer sleep compartment for vehicles such as aircraft. [Background technology]

[0002] Passenger aircraft usually have different passenger classes, such as first class, business class, premium economy and economy class. Airlines offer different services to cater to different passenger needs and paying abilities. Generally, first class and business class are more expensive and have more comfortable and spacious accommodations (including lie-flat sleeping options) since each seat can occupy a larger footprint in the cabin.

[0003] However, passenger density in economy class is generally higher (more passengers seated in each area). Economy passengers generally struggle to rest and / or get continuous, uninterrupted deep sleep (without sleeping pills or aids) during the flight. After a long flight, this can leave passengers exhausted at their destination.

[0004] To improve comfort, economy seats on aircraft may recline slightly. However, these seats typically cannot recline to a flat or near horizontal position because this would encroach on the space of passengers in the row behind. In the economy section of an aircraft, passengers are generally required to sit or sleep upright for long periods of time and may not have enough space to stretch out (especially for taller passengers), which can create a high barrier to comfort and sleep.

[0005] It may be desirable to provide accommodations for economy and / or premium economy passengers on an aircraft that provide increased comfort and / or reduced barriers to rest or sleep compared to "standard" economy seats. Accommodations for economy passengers may be desirable to accommodate a high density of passengers in an area of ​​the cabin in order to keep the cost for each passenger relatively low and / or to maintain or increase airline profits.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0057] According to various aspects of the present invention illustrated in Figures 1-10, there is provided a multi-layered sleep compartment 1. The multi-layered sleep compartment 1 is configured for use in passenger vehicles, and in particular in aircraft (civilian aircraft as well as private or corporate aircraft).

[0058] It will be understood that these diagrams illustrate general principles of construction, layout and configuration, and the invention is not limited to the precise configurations shown.

[0059] 1, in a preferred configuration, the multi-layered sleeping compartment 1 comprises a housing 10 and an entrance 11 to the sleeping compartment 3. As shown in FIG. 7, the housing 10 of the sleeping compartment 1 at least partially isolates or separates the sleeping compartment from the open cabin area 3 of the aircraft 2.

[0060] The housing 10 of the sleeping compartment 1 preferably has at least side walls 17 and a rear (or front) wall 18. In a preferred configuration, the compartment also has a top cover 16 and / or a floor. When assembled, the housing 10 isolates the sleeping pod 20 from the open cabin area 3, but in order to install the sleeping compartment 1 on an aircraft, the housing 10 (and other components of the compartment) are split into multiple pieces to fit through the aircraft doors 15 and then installed on the aircraft.

[0061] For example, the sleeping compartment 1 may be divided into six or more parts to fit through an aircraft door 15, as shown in Figure 10. Preferably, the compartment is designed for easy installation and assembly.

[0062] In a preferred configuration, the entrance 11 to the sleep compartment 1 is located at an end 12 of the sleep compartment. Most preferably, the entrance 11 is located at only one end 12 of the sleep compartment to reduce noise, odors, or other disturbances from the passenger cabin area 3 from entering the compartment. In other configurations, the entrance 11 may be located at both ends 12, 13 of the sleep compartment 1, for example for ease of access.

[0063] In a preferred configuration, the entrance 11 is not located at a side 14 of the sleeping compartment (see FIG. 3). An entrance 11 located at an end of the sleeping compartment 1 can be isolated from the longitudinal aisle 7 of the aircraft and can provide advantages, as will be explained in more detail below.

[0064] Optionally, curtains, sliding doors, or other screening may be installed at the entrance 11 to improve privacy and / or separation of the sleeping pod passengers from other passengers and crew on the aircraft.

[0065] Preferably, the multi-layered sleeping compartment 1 is an independent monument that can be installed in an aircraft (or other passenger vehicle). In a preferred configuration, the sleeping compartment 1 is provided with attachment points for connecting the compartment to the ceiling of the aircraft.

[0066] Sleeping Pod Layout The multi-layered sleeping compartment 1 comprises a number of sleeping pods 20. The sleeping pods 20 are positioned within the housing 10. The sleeping pods 20 are designed for passengers to rest during flights, especially during long flights, some of which can be up to 18 hours. The sleeping compartment 1 can be used for short, medium, long or extra long distance travel.

[0067] The sleep pods 20 provide a space on the aircraft 2 for passengers 4 to lie down, sleep, rest, or simply escape their seats during flight to a more private space to lie down, thus improving the flight experience.

[0068] In a preferred configuration, each sleeping pod 20 comprises a permanently flat bed surface. Preferably, the sleeping pods 20 are flat with a horizontal surface in a horizontal or nearly horizontal position on the aircraft. In some configurations, the bed surface may have a slight angle (e.g., 3 degrees from horizontal) to accommodate the flight angle of the aircraft during flight, so that the bed surface is nearly horizontal / flat. Because the bed surface has a slight angle, passengers should feel completely flat when the aircraft is flying. People usually sleep better on a flat surface, which provides more space for passengers to stretch their legs. Preferably, the sleeping pods are permanently fixed in a flat configuration, i.e., the beds do not fold or unfold. A permanent bed structure is easier and cheaper to manufacture, more stable, and may not require time to set up (move into place) for each passenger.

[0069] Preferably, a mattress or other soft surface is provided for each sleep pod 20 on the flat bed surface. The mattress may comprise a comfortable resilient material such as foam and be backed with a more durable material such as cloth or leather.

[0070] The multi-layer sleeping compartment 1 may be particularly suitable for wide-body aircraft, which typically have two aisles 7. Wide-body aircraft are typically over five metres wide and have between seven and ten seats abreast.

[0071] The sleep compartment 1 may be installed in a range of aircraft, including, but not limited to, a 787, 777, 747, 767, A340, A350, A380, etc. It is to be understood that the sleep compartment 1 may be installed in other existing and future aircraft models, or other vehicles for transporting passengers.

[0072] In a preferred configuration, the rows of seats 9 extending from the sides of the aircraft adjacent to the sleeping compartment do not need to be removed in a wide-body aircraft. Preferably, the width of the sleeping compartment 1 is limited so that only the seats in the central section between the longitudinal aisles 7 need to be removed.

[0073] It is anticipated that the multi-layered sleeping compartment 1 may be installed in narrow-body aircraft with no or minor modifications to the present invention. For example, the sleeping compartment 1 may be installed in a 737 or A320, which have a cabin height similar to that of wide-body aircraft. The multi-layered sleeping compartment 1 may also be installed in customized narrow-body private / corporate or charter aircraft. In some configurations, one or more side seats may be removed to create space for the sleeping compartment 1.

[0074] Aircraft generally have limited cabin space for passengers. The multi-layered sleep compartment 1 of the present invention may be particularly beneficial in the economy class of an aircraft. Since passenger density in the economy class of an aircraft is generally high (more passengers seated in each area), the cost for each passenger may be lower than other seats on the aircraft. The sleep compartment 1 of the present invention may provide a sleep pod 20 in a limited footprint.

[0075] In order to accommodate the sleep pods 20 in a limited footprint within an aircraft, the layout, orientation and location of the sleep compartments 1 are important considerations.

[0076] Preferably, the sleeping pods 20 are located on a pod first side 21 and a pod second side 22. Both pod sides 21, 22 can efficiently fit into the center area of ​​a conventional wide-body aircraft. Utilities, services, and / or entrances 11 can be located between the two pod sides 21, 22, as described below.

[0077] It should be appreciated that having two sides 21, 22 of the pod (rather than one side) may provide certain advantages. The two sides 21, 22 of the pod efficiently use space within the aircraft cabin to provide more sleeping pods 20 for a given compartment footprint. Providing more sleeping pods 20 for passengers can help cover the costs of manufacturing and / or installing the sleeping compartments 1. Having two sides 21, 22 of the pod also provides a central lobby area 30 (discussed in more detail below) that efficiently uses space within the cabin to provide access to the sleeping pods 20 away from the aisle 7.

[0078] In a preferred configuration, the first and second sides 21, 22 of the pod are mirror symmetric (ie, they are symmetric along the longitudinal axis).

[0079] Preferably, each side 21, 22 of the sleeping pod has at least a top pod 23 and a bottom pod 25. The sleeping compartment 1 has a multi-layer compartment layout with two or more layers or bunks on each side. It should be appreciated that the multi-layer sleeping compartment 1 can accommodate more sleeping pods 20 for passengers to rest in for a given compartment footprint. The multi-layer structure uses vertical space within the aircraft cabin.

[0080] In some configurations, one or both sides 21, 22 of the sleeping pod have one or two middle sleeping pods 24 between an upper sleeping pod 23 and a lower sleeping pod 25 (i.e., a three or four layer sleeping pod). In the most preferred illustrated configuration of Figure 2, the sleeping compartment 1 has three layers of sleeping pods 20 on each side 21, 22 (an upper sleeping pod 23, a middle sleeping pod 24, and a lower sleeping pod 25). Note that the right side wall of the compartment is hidden in Figure 2 to show the interior features of the compartment.

[0081] In a preferred configuration, the sleeping compartment 1 has two to three layers of sleeping pods, balancing the desire to accommodate more passengers in the sleeping compartment 1 at the limited height of the aircraft with the comfort of each passenger.

[0082] Preferably, the sleeping pods 20 on each side 21, 22 are aligned in a plan view (ie, not arranged in a staggered configuration).

[0083] In some configurations, the vertical spacing between the sleeping pods 20 is uniform.

[0084] In a preferred configuration, the vertical spacing between the sleeping pods 20 is non-uniform to improve access and / or to accommodate different passengers. For example, the lower sleeping pods 25 have a greater vertical spacing compared to the upper pods to improve access to the lower sleeping pods.

[0085] The number of layers of sleeping pods 20 in a sleeping compartment 1 is limited by the vertical height of the aircraft. It is expected that the sleeping compartment 1 could have more layers of sleeping pods 20 if the aircraft could accommodate the height of the sleeping compartment.

[0086] Central Lobby Area In a preferred configuration, the multi-layered sleeping compartment 1 comprises a central lobby area 30. The entrance 11 of the sleeping compartment 1 provides access to the central lobby area 30. Preferably, the central lobby area 30 is located between the pod first side 21 and the pod second side 22.

[0087] The central lobby area 30 provides a space for passengers to prepare and enter the sleep pod 20. This area may also be used by flight attendants to perform safety checks on passengers and provide necessary assistance during the passenger's session in the sleep pod. The central lobby area 30 is located within the multi-layered sleep compartment 1 and is isolated from the aisle 7 of the aircraft. Having a central lobby area 30 separated from the sleep compartments may be beneficial as it allows sleep pod passengers time to enter their sleep pod. In contrast, if a passenger needs to enter a sleep pod 20 that is in the aisle 7 of the aircraft, this may impact other passengers, flight attendants or galley carts trying to pass and / or the passenger may feel rushed as they board the pod in close proximity to passengers seated on the side of the aircraft. The central lobby area 30 may reduce embarrassment and confusion and allow for a more dignified and comfortable entry into the sleep pod 20.

[0088] The central lobby area 30 is preferably wide enough to accommodate an aircraft aisle chair (which is narrower than a standard wheelchair) so that passengers with reduced mobility can use the sleep pods 20. The aircraft aisle chair may have a special "booster" to lift the passenger to the same height as the mid-level pods 24. This allows the passenger to slide into the sleep pods 20 with dignity, requiring limited strength.

[0089] Preferably, the central lobby area 30 provides side access to the sleeping pods 30 inside the sleeping compartments 1 as indicated by the side access arrows (S) in FIG.

[0090] Most preferably, sleeping pod passengers enter / walk into the sleeping compartment 1 at the entrance 11 at the end of the sleeping pod and enter / climb through the side of the individual sleeping pod 20, as shown by arrow (S) in FIG. 3.

[0091] Side access to the sleeping pods 20 is more natural and comfortable for passengers compared to end access to the sleeping pods. Preferably, side access to the sleeping pods (S) provides an entrance experience similar to a conventional bed or berth to allow passengers to access each pod from the side.

[0092] Additionally, side sleeping allows passengers to escape from the sleep pod 20 more easily and quickly, which is particularly important in the event of an emergency.

[0093] In contrast, end access to sleeping pods can be an undesirable experience, as it can be uncomfortable or difficult to get in and out of the ends of a long, narrow sleeping pod (especially for passengers with limited mobility).

[0094] In a preferred configuration, the length of the side rests (S) is at least 70 cm (i.e. the space open for the side rests is at least 80 cm long). More preferably, the length of the side rests is at least 100 cm.

[0095] Optionally, curtains, sliding doors, or other screening 47 may be installed along the sides of the sleeping pod 20, as shown in FIG. 2, to improve privacy and / or separation of the sleeping pod's passengers from one another.

[0096] A central lobby area 30 extends longitudinally into the sleeping compartment 1. In a preferred configuration, the central lobby area 30 extends from the entrance 11 to approximately halfway into the sleeping compartment 1. It is envisioned that in the sleeping compartment 1, the central lobby 30 can be any size, but can also balance the desire to provide sufficient space for passengers and crew to stand in the sleeping compartment and / or for passengers to enter the sleeping pod 20 along the sides of the sleeping pod 20, while maintaining a limited compartment footprint within the cabin.

[0097] Preferably, the sleeping pod 20 has a head region 27 at the end of the sleeping compartment away from the entrance. Preferably, the sleeping pod 20 has a foot region 28 towards the entrance 11.

[0098] It is anticipated that keeping head region 27 away from the entrance will reduce disruption to passengers resting in their pods while other passengers enter the pods where they are sleeping.

[0099] Preferably, the widest portion of the sleeping pod 20 is at the sleeping pod's head region 27. Having a wider head region 27 may improve passenger comfort and reduce the likelihood of feeling claustrophobic.

[0100] Optionally, the sleeping pod 20 is provided with soft or cushioned walls 31 (as shown in FIG. 2) to improve the safety and / or comfort of passengers within the sleeping pod. Preferably, the soft walls 31 are located at least at the head end 27 of the sleeping pod.

[0101] In a preferred configuration, the central lobby area 30 is approximately trapezoidal or triangular in plan view, such that the width of the central lobby area increases toward the entrance, as shown in Figure 3. The wider area toward the entrance may allow passengers some space to get ready before climbing into their sleeping pods 30.

[0102] Preferably, the width of the entrance 11 is 50 to 100 cm.

[0103] More preferably, the width of the entrance 11 is 60 to 85 cm.

[0104] Preferably, the sleeping pod 20 narrows towards the entrance end 28 of the sleeping pod 20, and the width of the sleeping pod narrows towards the entrance 11 to allow for a wider central lobby area. As the sleeping pod 20 narrows towards the entrance, more space is provided for the central lobby area 30 towards the entrance 11 of the sleeping compartment 1. Preferably, the narrowing of the sleeping pod 20 is in the less critical foot area 28 of the sleeping pod (the foot area is located towards the entrance end of the sleeping pod). The less critical foot area 28 is reduced so that there is more space for the central lobby area 30. Preferably, both sides of the sleeping pod 20 narrow towards the entrance 11, forming an approximately V-shape in plan view, providing an approximately trapezoidal or triangular central lobby area 30.

[0105] Preferably, the shorter side of the trapezoidal central lobby area 30 is adjacent to the central vertical console.

[0106] Preferably, the front face of the central vertical console 40 is adjacent to a short side of the trapezoidal central lobby area.

[0107] In a preferred configuration, the sleeping pod 20 is generally rectangular in plan, except that it narrows towards the entrance 11, as shown in FIG.

[0108] In some configurations, the side of the sleeping pod 20 adjacent the central lobby area 30 in plan view is generally angled, with the side of the sleeping pod adjacent the central lobby area tapering to allow for a larger central lobby area. Preferably, the angled side of the sleeping pod 20 is not parallel to the longitudinal axis of the pod. Preferably, the side of the sleeping pod 20 adjacent the central lobby area is tapered to reduce the sleeping pod width, with the sleeping pod having a generally rectangular envelope and a chamfered / notched side adjacent the central lobby area 30, preferably in the region where the passenger's feet rest.

[0109] Preferably, the sleeping pod 20 narrows such that the angled side walls are at an angle of 10° to 20° from the longitudinal axis of the sleeping compartment (the angle referenced as 29 in FIG. 3).

[0110] Orientation and location of sleeping compartments in aircraft In the preferred configurations, the sleeping compartment 1 is generally aligned with the aircraft longitudinal axis 6 of the aircraft 2. The sleeping compartment 1 is considered to be generally aligned when the sleeping compartment is fore-aft such that the sleeping compartment is oriented longitudinally along the aircraft 2. In these configurations, passengers in the sleeping pods lie generally in line with the longitudinal axis 6 of the aircraft 2, taking into account that the passenger may choose to lie "across" the bed surface at an angle.

[0111] Preferably, the outer side walls of the sleeping compartment 1 are parallel or nearly parallel to an aisle 7 running longitudinally along the aircraft.

[0112] Preferably, the front and rear outer side walls of the sleeping compartment 1 are approximately perpendicular to the aisle 7 running longitudinally along the aircraft.

[0113] In preferred configurations, each sleeping pod 20 is elongated. Preferably, the sleeping pods 20 are longitudinally arranged such that each sleeping pod has a pod longitudinal axis 26 that is substantially parallel to the aircraft longitudinal axis 6 of the aircraft 2, as shown in the passenger accommodation layout (LOPA) of Figure 7. In these configurations, the length L (see Figure 3) of the sleeping compartment 1 is oriented along the aircraft longitudinal direction, which has a longer dimension than the aircraft transverse direction.

[0114] The longitudinal axis 26 of the sleeping pod 20 preferably extends perpendicular to the front and rear ends 27, 28 of the sleeping pod. Typically, the longitudinal axis 26 of the sleeping pod 20 is aligned with the outer sidewalls of the sides of the sleeping compartment 1.

[0115] In a preferred configuration, the sleeping compartment 1 is located on or towards the centre line 5 of the aircraft body 2. In a most preferred configuration, the sleeping compartment 1 is located along the centre line 5 of the aircraft body 2, as shown in FIG.

[0116] In a configuration in which the sleeping compartments 1 are located at or toward the centerline 5 of the aircraft body, each sleeping pod 20 may have more space than in other configurations. In contrast, if the beds are located at the sides of the aircraft, the aircraft side walls may limit the space of one or more of the sleeping pods because the aircraft side walls are generally curved. The space of at least the top pod 23 may need to be reduced and / or may not match the lower pods 24, 25.

[0117] Additionally, the vertical height of the aircraft is generally greatest toward or towards the center 5 of the aircraft. In configurations where the sleeping compartments 1 are located at or towards the centerline 5, more layers of sleeping pods may be installed and / or each passenger may have more vertical space in each sleeping pod. For example, a sleeping compartment 1 with two, three or four layers of sleeping pods 20 may be installed in this central location.

[0118] In a configuration in which the sleeping compartment 1 is positioned at or towards the centerline 5 of the aircraft body, fewer rows of seats may need to be removed to achieve the same density of sleeping pods compared to a sleeping compartment positioned against a side wall of the aircraft.

[0119] In a preferred configuration, the sleeping compartment 1 is located between two aisles 7 of the aircraft, as shown in Figure 3. Preferably, the sleeping compartment 1 fills the entire space of the central section of the entire aircraft (i.e. it is directly between the aisles and there are no seats in the space between the compartment and the aisle).

[0120] The sleeping compartments 1 are located between the aisles 7 that run longitudinally along the aircraft and are generally used for the passage of passengers, crew, baggage, etc. Preferably, the sleeping compartments have a width W that allows space and comfort for passengers within the sleeping pods, while balancing the need to ensure sufficient aisle space for passengers, baggage, crew, and catering equipment to pass through the aisle. In these configurations, passengers can access the entrances 11 of the sleeping compartments 1 from either aisle 7, thereby improving access to the sleeping pods 20.

[0121] In some configurations, the sleeping compartments 1 are positioned such that their entrances 11 are at a cross aisle 8 of the aircraft. The cross aisle 8 is an open space for passengers to pass from one side of the aircraft to the other. Generally, the width of the cross aisle 8 is wider than the space between the rows of seats 9, and generally wider than the aisles 7 running longitudinally through the aircraft. Additionally, some cross aisles are aligned with one (or a pair) of the aircraft doors 15.

[0122] A sleep compartment 1 positioned at a cross aisle 8 may provide advantages such as easier access to the sleep compartment 1 since there is generally more space at the cross aisle. Additionally, a sleep compartment 1 positioned at a cross aisle 8 may reduce the number of seats 9 that may need to be removed from the center area of ​​the aircraft (more rows of seats can be longitudinally aligned with the sleep compartment).

[0123] In a preferred configuration, the sleeping compartment 1 is located longitudinally adjacent to the monument. The sleeping compartment 1 is "adjacent" to the monument, and there is no row of seats between the sleeping compartment 1 and the monument. In some configurations, the monument is a lavatory 50, as shown in FIG. 7.

[0124] In these configurations, the location of the sleeping compartment 1 (adjacent to the monument) may provide certain advantages in an aircraft or other passenger vehicle. As shown in FIG. 7, the entrance 11 of the sleeping compartment 1 faces the side wall of the lavatory 50. Passengers can enter the sleeping compartment 1 without disturbing passengers seated at the rear of the compartment. The introduction of the sleeping compartment 1 in an aircraft may potentially increase the number of pedestrians in the area leading to the entrance 11 of the compartment. In general, the extra traffic through the monument is preferable to the extra traffic through (especially in front of) the passengers in the seats 9. Typically, it would be desirable to minimize pedestrian traffic in front of the row of seats 9 in order to minimize disturbance to passengers seated in these seats.

[0125] Furthermore, in these configurations where the sleeping compartment 1 is adjacent to a monument, it may be necessary to remove fewer rows of seats along the aircraft to provide space for the sleeping compartment 1, thereby making efficient use of the space in the aircraft cabin 3.

[0126] It is envisaged that the sleeping compartment 1 may be oriented either towards the front or the rear of the aircraft depending on the desired cabin configuration.

[0127] Positioning the sleeping pods 20 longitudinally along the centerline of the aircraft 2 and / or located between the two aisles 7 can provide particular advantages compared to aircraft having conventional passenger accommodation arrangements.

[0128] In configurations in which the sleep compartment 1 has one or more of these features, these functions act synergistically to provide an efficient compartment footprint within the passenger compartment and / or other benefits.

[0129] These features of the sleep compartment 1 may provide for more sleep pods 20 within an efficient footprint. Because of the efficient footprint of the sleep compartment, more seats or more sleep compartments may be installed on an aircraft.

[0130] In contrast, if the sleeping pods 20 are arranged horizontally across the width of the aircraft body extending from the side walls of the aircraft, the number of tiers of sleeping pods may be limited. In a typical wide-body aircraft, only two tiers of sleeping pods 20 may be provided. If three tiers of sleeping pods are installed, the sleeping compartment 1 must extend to the aisle 7, thus requiring the removal of an additional centerline seat.

[0131] Alternatively, if the sleeping pod 20 were positioned horizontally across the centerline of the aircraft, the sleeping compartment 1 might extend too far into the aisle 7, necessitating the removal of additional exterior seats in addition to removing the centerline seats.

[0132] Additionally, these features may improve access to the sleeping pod: the location, orientation, and layout of the sleeping compartment 1 may allow for side-lying into the sleeping pod (shown as arrow S in FIG. 3).

[0133] It is envisioned that one or more sleeping compartments 1 may be installed on an aircraft. In some configurations, an aircraft may have multiple sleeping compartments 1 positioned along the aircraft.

[0134] In a preferred configuration, the height (H) of the sleeping compartment is 210-260 cm (external dimensions), as referenced in FIG.

[0135] In a preferred configuration, the width (W) of the sleeping compartment is 120-160 cm (external dimensions), as seen in FIG.

[0136] In a preferred configuration, the length (L) of the sleeping compartment is 180-230 cm (external dimensions), as referenced in FIG.

[0137] Central vertical console and steps In a preferred configuration, the multi-layered sleep compartment 1 has a central vertical console 40 located between the pod first side 21 and the pod second side 22 .

[0138] The central vertical console 40 houses services including one or more combinations of air conditioners / air gas pars, smoke detectors, electrical wiring, ducting, charging ports, lighting, illuminated signs, crew call buttons, oxygen mask modules, safety belts (e.g., the belt connection points are located in the console), life jackets, other passenger utilities, or emergency and safety systems. In some configurations, the central vertical console 40 includes a PSU panel 41 (passenger service unit) with electronic interfaces such as lighting, crew call buttons, etc., as shown in FIG. 9. Preferably, the PSU is located toward the passenger's head when the passenger is lying on the sleep pod 20. The central vertical console 40 may also have an IFE screen (in-flight entertainment), headphone jack, Bluetooth or other wireless audio connection, storage, or speakers.

[0139] It is anticipated that other services or utilities known to those skilled in the art may be included in the central vertical console 40 .

[0140] The central vertical console 40 provides a structure for efficient use of space within the sleeping compartment 1 to store and / or provide the services described above. By housing the wire and / or piping runs and electrical systems in the central vertical column rather than running the runs within the exterior wall or ceiling panels of the pod, passenger space in each sleeping pod 20 can be maximized.

[0141] Preferably, the central vertical column 40 is hollow to accommodate utilities and services.

[0142] In a preferred configuration, the central vertical post 40 is generally rectangular in plan view. In some configurations, a PSU (Passenger Service Unit) protrudes from the central vertical post 40 such that the unit is above or near the passenger's head area.

[0143] Preferably, a central vertical post 40 extends from the ceiling 19 to the floor of the sleeping compartment.

[0144] The central vertical pillar 40 minimizes the complexity of manufacturing and installing the different utilities and services. Preferably, the central vertical pillar 40 can accommodate the utilities and services for both the first side 21 and the second side 22 of the pods, as well as the different layers of those pods.

[0145] Additionally, the central vertical post 40 has a structure that allows it to be easily assembled with other components of the sleep compartment 1, as shown in FIG.

[0146] In some configurations, the central vertical console 40 is located at or toward the end 13 of the sleeping compartment opposite the entrance 11 (i.e., the rear end 13). In other configurations, the central vertical console 40 is positioned toward the center of the sleeping compartment.

[0147] In some configurations, the central vertical console extends approximately halfway along the compartment from the rear end 13 of the sleeping compartment towards the entrance 11.

[0148] In a preferred configuration, the central vertical console 40 at least partially forms a barrier or screen between the first side 21 and the second side 22 of the pod. Preferably, the central vertical console 40 forms a physical barrier or screen at least between the head region 27 of the first side 21 and the second side 22 of the pod. The central vertical console 40 may act as a sound and visual barrier between passengers within the sleeping pod 20. A physical barrier may also improve the safety of the sleeping pod 20 as it may reduce the risk of a passenger getting too close to the end of the pod and rolling off.

[0149] In a preferred configuration, the central vertical console 40 has a width (between the first and second sides) of 15-40cm.

[0150] Preferably, the sleeping compartment 1 has a ramp 48 located between the pod first side 21 and the pod second side 22 for accessing the upper sleeping pods 23. A centralized ramp for the upper sleeping pods 23 on both sides 21, 22 (rather than separate ramps on each side) may increase the space efficiency of the sleeping compartment 1.

[0151] In some configurations, the steps 48 are located at or towards the end 13 of the sleeping compartment opposite the entrance 11. In other configurations, the steps 48 are located towards the center of the sleeping compartment.

[0152] In some configurations, the lifting stage 48 is integral with the central vertical console 40. The lifting stage 48 may be permanently or removably secured to the central vertical console 40.

[0153] In a preferred configuration, the steps 48 are provided as stairs or the like (i.e., not rungs like a ladder) as shown in FIG. 6. Stairs or similar structures can provide touch points that are familiar, intuitive, and safer to use, especially for passengers using a sleep pod for the first time. Stairs or similar structures can also be beneficial for passengers with limited mobility, who are sleepy and / or awakened from sleep, or who have had the cabin lights dimmed.

[0154] A centralized staircase space may be provided in a configuration where there is a central lobby area 30 between the sleeping pods 20.

[0155] In some configurations, the steps 48 provide an additional barrier or screen between at least the passengers in the bottom level of the sleeping pods 25, as shown in FIG.

[0156] In other configurations, it is anticipated that a ladder, a recessed access step in the central vertical console, or other access steps may be incorporated into the sleeping compartment 1 as would be known to one of ordinary skill in the art.

[0157] Preferably, the sleeping compartment 1 has one or more handles 49. The handles can assist the passenger when climbing the steps 48 and for entering and staying in the sleeping pod 20.

[0158] Preferably, the handle 49 is integral with the central vertical console 40. In some configurations the handle 49 is recessed into the central vertical console 40, as shown in Figure 5. In other configurations the handle 49 may be attached to an exterior surface of the central vertical console.

[0159] In other configurations, the handle 49 is integrated with the sleep pod 20. For example, in some configurations, the handle 49 is integrated into the underside of the pod. In some configurations, the handle 49 is extended during use and retracted into a recess (preferably flush with a surface) when not in use to reduce the risk of a head strike.

[0160] It is envisaged that the handle 49 may be integrated into other areas of the sleeping compartment 1, such as the steps 48, the ceiling, etc.

[0161] ceiling In a preferred configuration, the sleeping compartment 1 has an elevated ceiling area 19 that is elevated to the ceiling of the aircraft (i.e. elevated relative to the ceiling of other parts of the aircraft) to provide additional head space, as best shown in Figure 8. The elevated ceiling area 19 is preferably in at least the area above the stairs 48.

[0162] The high ceiling area 19 provides more headroom and enables passengers to reach the top step 48 and safely and comfortably enter the upper sleeping pod 23. Preferably, the high ceiling area 19 has a dome shape that is recessed into the otherwise flat ceiling of the sleeping compartment 1.

[0163] The high ceiling area 19 can improve access and the ergonomic experience for passengers (especially taller passengers) who may need to be able to stretch their head (and upper body) while on the top rung so that they can safely and more easily slide into the upper pod. This feature can be particularly useful for sleeping compartments 1 with three (or more) layers of sleeping pods, where each sleeping pod is low in height and the upper sleeping pods 23 are closer to the ceiling.

[0164] In contrast, the flat ceiling of a typical aircraft cabin may not provide enough space for a passenger on the topmost tier to comfortably enter an upper sleeping pod, and may require them to simultaneously sit on the tier and contort their body to slide into the upper sleeping pod.

[0165] Preferably, the high ceiling area 19 is recessed into the aircraft ceiling by 10-35 cm. The high ceiling area 19 is preferably recessed above a typical monumental height, e.g. a galley or lavatory.

[0166] More preferably, the high ceiling area 19 is recessed into the aircraft ceiling by 23 to 28 cm.

[0167] Reservation Sessions It is anticipated that the sleep pods 20 may be utilized in a number of ways. For example, the sleep pods 20 may be reserved by a passenger for an entire flight or for a portion of a flight.

[0168] In a preferred booking model, passengers can book a sleep pod 20 for a session time that is much shorter than the total flight time.

[0169] Passengers preferably remain in their seats (and not in their sleep pods) for taxiing, takeoff and landing (TTL). Passengers are moved to the sleep pods 20 only after it is safe to do so. This booking model takes into account current regulations related to TTL. For example, the cruise flight time (excluding TTL) could be divided into multiple sessions where passengers can book to occupy a sleep pod.

[0170] It is anticipated that in other booking models, the sleep pod 20 may be booked only as an accommodation (and not as an addition to a seat). Minor modifications to the sleep compartment 1 may be included to meet safety and / or other airline regulations.

[0171] Modeling a preferred reservation may depend on many considerations, such as flight duration, scheduled meal times, announcement times, takeoff and landing procedures, etc.

[0172] Preferably, the sleep pods 20 can be reserved for a block of time, for example 1 hour, 1.5 hours, 2 hours, 4 hours, 6 hours, 8 hours, 10 hours, 12 hours, 14 hours, etc., or for the entire flight.

[0173] Since passengers may not want to lie down for the entire flight, it may be beneficial to have multiple sessions available for the sleep pod 20 (especially for ultra-long haul flights). Multiple sessions allow more passengers on the flight to benefit from the sleep pod. Additionally, a limited session time may reduce the cost of each session for the passenger (as the cost of booking an entire flight may be prohibitively high) and / or increase profits for the airline. Optionally, passengers may not be able to book multiple sessions on the same flight.

[0174] At the end of the session, passengers can be woken up by the flight attendant, mood lighting, sound, personal devices, or a combination of these, and asked to return to their seats and / or prepare for landing.

[0175] For example, a booking model for a flight from 13 to 17 hours could have approximately the following timetable: a) Boarding, takeoff, ascent, b) 3 x 4 hour sleep pod sessions, c) Descent and landing.

[0176] It is anticipated that the session lengths may be the same or different depending on how one wishes to divide up the cruise flight time.

[0177] Preferably, a safety briefing is delivered (e.g., by the crew or by video) to passengers using the sleep pod 20 prior to or at the start of a sleep pod session. Safety checks may be performed periodically by the crew to check on sleeping pod passengers (e.g., every 30 minutes or hour).

[0178] In a preferred booking model, sleep pod passengers are scheduled to enter and exit sleep compartment 1 within designated intervals to minimize disruption to other resting or sleeping passengers in the compartment. For example, the schedule for most or all sleep pod passengers in a compartment to enter and exit a sleep pod may be within approximately a 20-minute, 30-minute, or 40-minute window.

[0179] In a preferred booking model, the schedules of sleep pod passengers entering / exiting sleep pods 20 are staggered. This can provide the advantage of allowing each passenger to have the space and privacy to enter / exit their sleep pod 20 without other sleep pod passengers trying to do the same. For example, each sleep pod passenger is scheduled to enter / exit sleep compartment 1 every 5-10 minutes within a particular time period (e.g., passengers enter / exit every 5-10 minutes within a 30 minute period).

[0180] It is anticipated that other booking model schedules may be used for the sleep pods depending on the airline's wishes. Considerations may include, but are not limited to, flight duration, flight regulations, and passenger and / or airline preferences.

[0181] In some booking models, passengers can pre-book a sleep pod 20 via an airline's website, a mobile app, an airline's check-in counter, a travel agent, etc. Preferably, the passenger can select a desired session time and desired booking pod location.

[0182] In some booking models, passengers may be able to reserve sleep pods 20 during the flight as desired or needed.

[0183] Different pricing may be applied to different sleep pods 20 (e.g., for sleep pod location, session time, type of equipment, and services provided within the pod). Airlines may choose to sell sleep pod 20 session times to premium economy and economy passengers, who typically have more compact seats during the flight. (overview)

[0184] The multi-layered sleeping compartment 1 can provide sleeping pods 20 for passengers who would otherwise typically be in a more compact economy seat, where passengers typically cannot stretch their legs or lie down. These sleeping pods provide passengers with a more comfortable and private area and can be particularly beneficial on long-haul or overnight flights. Offering these services can improve the passenger experience and therefore can make an airline more competitive than its competitors.

[0185] The features of the multi-layered sleep compartment 1 in a preferred configuration may act synergistically to provide one or more of the following advantages: a) the compartment has a housing 10 and an entrance 11 at the end (not the side) of the sleeping compartment, thus improving comfort and privacy; b) the entrance to the Sleeping Pod 20 is inside the compartment, not through a hallway, improving accessibility; c) safer and more natural side-lying into individual sleeping pods, as they can be accessed from the central lobby area 30; d) High passenger density as the sleeping compartments use the vertical space within the cabin to efficiently provide multiple sleeping pods due to the small area, the specific location of the compartments within the cabin, and the layout of the compartments; e) By providing a booking system that allows for multiple session times during the flight, the number of passengers able to use the sleep pods could be increased.
