Description

FIELD OF THE INVENTION

The field of this disclosure relates to passenger seats having improved comfort layouts and comfort features. Specific embodiments find particular use on-board passenger transportation vehicles, where a balance between comfort, space, and weight are desirably optimized.

BACKGROUND

Many vehicles such as passenger aircraft, buses, trains, ships, automobiles, and the like include seats for bearing passengers en route to a destination. The seats are designed with frames for supporting cushions, pads, and other seating components. A number of factors affect suitability of such passenger seats. For example, vehicle passenger seats are subject to safety requirements established by governments or other standard-setting organizations. Passenger comfort is also an important consideration in seat design. It is also desirable to reduce the seat's weight (e.g., which may directly affect an amount of fuel and corresponding cost to bear the seat between destinations) and general costs associated with a seat (e.g., cost of production, cost of installation, or cost of maintenance) in order to reduce overall operating costs. Airlines or other passenger aircraft operators may specify that seats for a particular aircraft or particular class level be of a particular size (e.g., have a specific maximum width or other dimension or fit within a specific footprint or area).

In many instances, passenger seats may be provided with various personal electronic and entertainment options to encourage passengers to remain seated as much as possible. This can help ensure passenger safety during transport, crew mobility, and to efficient cabin service. Some passenger seats provide video and audio entertainment, including television, video games, internet access, and other in-flight entertainment (“IFE”) components. Typically, these entertainment devices are mounted in the seat backs and/or arm rests of the passenger seats.

Passenger seats also may allow for recline or other relaxing positions. For example, most aircraft seats are provided with an upright position (often referred to as a taxi, take-off and landing (“TTL”) position), but that allow at least some amount of recline during travel. Some seats that are designed for extended flights have bed positions that allow the seats to fully recline or otherwise be extended to a flat (or close to flat) bed-like configuration. For these versions, the seat actuator components that provide the recline can be prone to mechanical difficulties, requiring various types of maintenance or repairs during the life of the seat in use. The seat actuator components that provide recline can also be heavy, adding additional weight to the seat system. The seat actuator components that provide recline can also be expensive to manufacture. Improvements are thus desirable.

SUMMARY

Accordingly, the present inventors have designed a passenger seat having improved comfort features, while eliminating the use of many of the typically-provided seat actuator components for recline. The passenger seat disclosed herein is designed to provide a comfortable sofa-like sitting position for a passenger, while also offering a comfortable lying position. The sitting position allows the passenger to face the forward direction of the vehicle (in line with many safety regulations). The lounging or lying down position allows the passenger to move around to achieve various comfort positions. In some examples, the seat back cushion portion can be divided into two separate sections in order to offer a passenger armrest. Further features are described herein.

DETAILED DESCRIPTION

The described embodiments provide improved comfort features and layouts for passenger seats. While the improved comfort features and layouts are described in connection with aircraft seats, they are by no means so limited. Rather, the embodiments disclosed may be used in passenger seats or other seats of any type or otherwise as desired.

According to certain embodiments illustrated by FIGS. 1-10, the disclosed passenger seat 10 has a seat portion 12 and a backrest portion 14, both of which are defined within or by a seat shell 16. Referring now to FIG. 1, it is shown that the angle α at which the seat portion 12 and the backrest portion 14 meet is generally greater than 90°, such that the seat occupant is allowed to have a natural recline when seated. This has been found to be a more comfortable position than providing a strictly upright seated position. One benefit of the disclosed passenger seat 10 is that there is not a seat actuator that allows movement of the backrest portion 14 with respect to the seat portion 12. The angle α between the seat portion 12 and the backrest portion 14 is static and fixed. Non-limiting exemplary angles α may be in the range of 100°-180°, which includes any angle between the seat pan and the backrest that ranges between the TTL position and the bed position. In a specific example, the range may be from about 110° to about 160°. In an even more specific example, the range may be from about 125° to about 145°. Providing a passenger seat 10 without use of the seat actuator helps reduce seat weight, seat expense, and seat complexity, without sacrificing passenger comfort due the other seat features disclosed herein. The passenger seat support (or skeleton or “bones”) may be defined directly by the seat shell 16 itself.

The backrest portion 14 is generally provided as being fairly wide, as compared to other passenger seat backs. The backrest portion 14 is also provided as having a rounded or curved-like configuration that encloses the passenger for privacy, as well as comfort. In one example, the backrest portion 14 is actually defined by the seat shell 16 itself. The passenger is sitting on the seat shell 16 (albeit upon intervening cushions), rather than providing a seat unit that requires a completely separate seat shell. This can help reduce weight and complexity of the seat further.

The seat portion 12 has a sitting area 40 and a side ottoman feature 42. The side ottoman feature 42 provides a seat occupant with an area to raise his/her legs for a lounging rest position. As illustrated by the overhead view of FIG. 2, the side ottoman feature 42 may extend from one side of the sitting area 40 and alongside a seat shell 16 of a forward seat F. The side ottoman 42 may be integrated with the sitting area 40/seat pan to provide a one-piece cushioned bed/lounging experience. This design can provide a space saving benefit. It allows passengers to prop up their legs, without requiring a full leg space in front of the seat. The general concept and feel of the passenger seat 10 is to provide a couch-like experience for the passenger. The passenger can move to various positions within the seat. An open space 44 is provided immediately forward of the sitting area 40. This open space 44 allows a passenger to sit upright, with his/her legs positioned in the open space 44. In one example, the portion at which the side ottoman feature 42 projects from the sitting area 40 creates an L-shaped area 46 that helps define the open space 44. The combined sitting area 40 and the side ottoman 42 offer a cushioned lounging space. Although not shown, it is possible to provide a one piece cushion covering the entire lounging space defined by sitting area 40 and side ottoman 42. In another example, it is possible to provide multi-piece cushions that are separately removable from the passenger seat 10.

In order to convert the passenger seat 10 into a bed, which would allow the seat occupant to lie flat back, there is provided a bed extension 50. Bed extension 50 is generally illustrated as a square-shaped insert that fits into the open space 44. However, it should be understood that bed extension 50 may take any appropriate shape that is necessary to at least partially or at least fully cover the open space 44. In one example, the bed extension 50 may be a separate insert that sits upon a ledged area for positioning. In another example, the bed extension 50 may be a sliding insert that may retract into (and underneath) a forward seat F/seat shell 16 and be moved in an aft direction (e.g., in these examples, backwards) into the open space 44 once bed conversion is desired. In another example, the bed extension 50 may be a sliding insert that may retract back into (and underneath) the sitting area 40 of the passenger seat 10 and be moved forward into the open space 44 once bed conversion is desired. In another example, the bed extension 50 may be a hinged extension that extends up and out from a seat base front portion 52. In a further example, the bed extension may be a hinged extension that extend up and out from a lower portion 54 of a forward seat shell 16. Other mechanical options for deploying and stowing the bed extension 50 are possible and considered within the scope of this disclosure. Once the bed extension 50 is in place, a seat occupant may use the passenger seat 10 much like a flat bed. The seat occupant's legs may extend onto the side ottoman 42 and the sitting area 40 may be used as a headrest. An optional pillow may be provided for comfort. The pillow may be an inflatable pillow that extends up from the sitting area 40. The pillow may be a separate pillow that is provided in one or more storage areas on the passenger seat 10.

FIG. 3 illustrates one example of a storage area 60 location, which is positioned near a lower portion 54 of a forward “F” seat shell 16. Additional or alternate storage areas 62 may be positioned underneath the side ottoman 42 and/or under the sitting area 40. In one example, it is possible to provide an access port 64 to a storage area contained within the side ottoman 42. The access port(s) 64 may be a hinged lid, a removable lid, a slidable lid, or any other appropriate means for accessing a storage area contained therebelow. An upper storage area 66 may be provided adjacent to the backrest portion. This upper storage area 66 may hinge open and be used to hold smaller passenger items such as phones or other electronic devices, books, reading glasses, work papers, or any other passenger items to be stowed but easily accessible. The upper storage area 66 may be enclosed by a swing open door 70, allowing a seat occupant to access the interior of the storage area 66 during travel. The storage area 66 may also define an upper surface 72 that may be used for additional storage or stowage. It is also possible to provide a side console 68. The side console 68 may serve as a drink rest, a hand rest, or as a small resting area for passenger items. The side console 68 may be provided as having a storage feature/area as well (accessible by raising or lowering a panel defining the side console 68).

An additional optional feature of the passenger seat 10 described herein is providing a cushioned resting area. The cushioned resting area may be defined by a traditional padded seat cushion. In another example, the cushioned resting area may be provided by one or more inflatable portions 74, illustrated by FIG. 4. If provided, the one or more inflatable portions 74 may be variably inflatable in order to allow a passenger to have different levels of lumbar or neck support. For example, it is possible to change the architecture of the seat using the one or more inflatable portions 74, which function as cushioning support. A user may wish to sit more upright or may otherwise wish to change the angle α between the sitting area and the backrest by inflating or deflating an inflatable portions 74. The one or more inflatable portion 74 may function similar to a lumbar support in an automobile. An additional option that may be added is providing a heated or cooled seat via use of the portion 74. The passenger may be able to achieve different combinations of firmness via use of the one or more inflatable portion 74.

As shown by FIG. 5, in an additional or alternate embodiment, the one or more inflatable portions 74 may be positioned along a side corner 76 of the backrest portion 14. It is believed that this embodiment may help provide additional back support for a seat occupant (specifically, along his/her spine) who is leaning against the side corner 76 with legs raised on the side ottoman 42. It may also be possible to increase the living space provided by the passenger seat for the lying down position when the one or more inflatable portions 74 are deflated. Controls for the one or more inflatable portions 74 may be positioned on an armrest, on the side console 68, on the forward video screen, on an overhead panel, or anywhere else that may be appropriate.

The description will now refer to the configuration of a plurality of passenger seats 10 described herein positioned on board a vehicle, such as an aircraft. FIG. 6 shows a seat shell 16A of a forward seat F, and a seat shell 16B of a rear seat R. Seat shell 16A may be designed to support a video monitor 18 and/or a tray table 20 and/or any other comfort component that is intended to be accessible by the seat occupant of the rear seat R (the seat located directly aft of the forward seat F). The video monitor 18 and/or tray table 20 may be mounted to the forward seat shell 16A using any appropriate installment methods. They may be hingedly secured, slidably secured, or securely mounted. It is also possible for the forward seat shell 16A to contain other accessory features, such as a headphone storage area 34, a storage drawer, one or more storage ledges, or any other optional features (not all shown). The seat shell 16B of the rear seat R functions similarly for a third seat that is positioned directly aft of the rear seat R, and so forth, along a vehicle.

As illustrated by FIG. 7, it should be understood that a number of passenger seats 10 enclosed by seat shells 16 may be provided along a plurality of rows 22. FIG. 7 provides only one example of a possible configuration. It should be understood that number of alternate passenger seat layouts are possible and considered within the scope of this disclosure. In this example, four rows 22 are provided along a longitudinal length 24 of the vehicle 26. A first row, 22A, is shown as positioned along a first vehicle sidewall 28A. Second and third rows 22B and 22C are shown as positioned along a central axis 30 of the vehicle 26. A first aisle 32A is created between rows 22A and 22B. A fourth row 20D, is shown as positioned along a second vehicle sidewall 28B. A second aisle 32B is created between rows 22C and 22D. The seat portions 12/sitting area 40 of each of the passenger seats 10 is generally positioned so that a seat occupant in a seated position is facing forward, in a direction along the central axis 30 of the vehicle. When and if a seat occupant chooses to lie down, his/her body would be angled with respect to the central axis 30. According to most safety regulations, this is an acceptable passenger position as long as the aircraft is not in taxi, takeoff, or landing (TTL). FIG. 7 also illustrates that the side ottomans of some of the passenger seats face in a first direction, whereas the side ottomans of other passenger seats face in a second direction. For example, side ottomans in row 22A face toward the first vehicle sidewall 28A, and side ottomans in row 22D face toward the second vehicle sidewall 28B. As illustrated, a forward/side portion of each ottoman may extend alongside a rear seat shell of the seat immediately forward. In the middle rows, 22B and 22C, the side ottomans face inwardly toward one another. A privacy wall may be present between these rows. For each passenger seat, the sitting area 40 is accessible by one of aisles for ease of entry and exit of the seats.

Although it is possible for the backrest portion 14 to be a continuous surface, FIGS. 8-9 show an alternate options for the backrest portion 14. In the version illustrated by FIG. 8, the backrest portion is provided with and upper portion 80 and a lower portion 82, defining a space 84 therebetween. In use, the upper portion 80 provides a head rest for the seat occupant. The lower portion 82 provides a lumbar support for the seat occupant. An upper surface 86 of the lower portion 82 may be used as an arm rest or an elbow rest. The space 84 formed between the upper portion 80 and the lower portion 82 provides an area for the passenger's arm and/or elbow to be received between the portions 80, 82. FIG. 9 illustrates a further embodiment, in which a space is not provided, but instead the lower portion 82 is superimposed upon one or more continuous backrest cushions 88. This version still provides an upper surface 86 that can serve as an arm and/or elbow rest, as illustrated. In an alternate embodiment, it is possible to provide a separate armrest component that tracks alongside portions of the backrest portion 14.

FIG. 10 illustrates a comparison between current aircraft seat designs 90 and the described passenger seat 10. FIG. 10A shows a current aircraft seat design 90, generally including a plurality of seat actuators for seat recline and/or for raising and lowering of a leg rest. The seat 90 provide a three-piece design, with a seat pan 92, a separate backrest 94, and a separate leg rest 96, all of which cooperate with respect to one another via actuators. When the seat 90 is moved to a flat bed position, there is typically not a seamless bed area provided due to the connection areas between the three components not being perfectly aligned in use.

By contrast, FIG. 10B shows one embodiment of a passenger seat 10 described herein. As shown, the seat 10 may be provided without any actuators required. The seat 10 provides a sitting area 40, a side ottoman 42, an open space 44 that may be enclosed via use of a bed extension 50, and a backrest 14. The back rest 14 may be divided into an upper portion 80 and a lower portion 82. The seat 10 is also shown as having a side console 68. As described above, other options may be incorporated into the passenger seat 10 that is shown. In one example, it is possible for the support portion of the backrest 14 (the back area) to be defined by the seat shell 16.

The passenger seat 10 may be formed of materials including but not limited to aluminum, stainless steel, carbon fiber, plastics or other polymers, injection molded or vacuum formed plastics, polycarbonate, polypropylene, honeycomb sandwich composite panels, other similar materials, or any other metallic or composite materials, or combinations thereof. The overlay cushions of the passenger seat may be any type of cloth, textile, leather, faux leather, plastic or rubber, polyvinyl fluoride, other vinyls, suede, any other appropriate material, or combinations thereof. In a specific example, interior support panels of the seat shell may be honeycomb sandwich composite panels, manufactured of Nomex.® The lower structure may be carbon fiber. Mechanisms on the passenger seat may be aluminum and/or stainless steel. Shrouds and stowage features may be injection molded and/or vacuum formed plastics.
