Description

The present invention relates to a seat unit and a seat arrangement.

In general, aircraft used for medium-to-long-haul flights have relatively large bodies, so they have multiple aisles and can also be equipped with business seats called full-flat seats, which allow passengers to lie flat even on long flights. You can relax and relax.

On the other hand, aircraft used for relatively short flights of about 3 to 6 hours often use smaller bodies, and a single aisle is located in the center of the fuselage along the longitudinal axis of the aircraft. The seats are often arranged in double rows on both sides, facing forward across the aisle.

Business seats on small aircraft like this have more space in the front and rear directions than economy seats, and the seats are wider, but it is difficult to say that there is enough space to stretch out your legs. Additionally, if a passenger sitting in a window seat attempts to access the aisle, he or she must pass in front of the passenger sitting in the aisle seat, which may unintentionally wake up the passenger sitting in the aisle seat, for example, if the passenger is sleeping. This can lead to awkward feelings for both parties. However, for short flights, passenger dissatisfaction with aisle access is relatively rare.

However, due to recent improvements in fuel efficiency technology, the cruising distance of aircraft has increased, and as flight times become longer, there is a risk that passenger dissatisfaction will become more apparent. For this reason, there is an urgent need to develop a seat unit that is as comfortable for aircraft used for short-distance flights as it is for aircraft used for medium- to long-distance flights.

On the other hand, according to the passenger suite disclosed in Patent Document 1, a seat facing the longitudinal direction of the aircraft and a seat facing the window are provided in one seat unit. All seats have good access to the aisle.

Special Publication No. 2015-512823

However, the passenger suite disclosed in Patent Document 1 is used in the first class of aircraft for medium and long-haul flights, and when applied to aircraft for short-haul flights, it consumes a lot of space inside the cabin. The problem is that the number of passengers will decrease significantly. In addition, it is not assumed that other people will sit on the seats facing the front and rear of the aircraft and the seats facing the window, and if other people use the passenger suite disclosed in Patent Document 1, There is a problem that private space cannot be maintained.

SUMMARY OF THE INVENTION An object of the present invention is to provide a seat unit and a seat arrangement that allow passengers to enjoy a comfortable flight even though the installation space is small.

In order to achieve the above object, the seat unit according to the present invention is a seat unit disposed between an aircraft window and an aisle.
In a seat unit placed between an aircraft window and an aisle,
a first seat, a second seat, and a third seat arranged along the longitudinal direction of the aircraft, each including a seat arranged on the aisle side and a backrest arranged on the window side;

Embodiments of the present invention will be described below with reference to the drawings. Note that in this specification, "forward" and "rear" refer to the direction of travel of the aircraft and the direction opposite to the direction of travel, respectively. The seat unit 10 of this embodiment can be used, for example, as a business class seat unit.

FIG. 1 is a top view (viewed in a direction perpendicular to the floor of the aircraft) showing a cabin of an aircraft 1 equipped with an aircraft seat unit according to the present embodiment. In FIG. 1, the left side of the drawing is the leading side of the aircraft 1, the right side is the rear side of the aircraft 1, and the longitudinal axis of the aircraft 1 is L. In the aircraft 1, a passage 3 is provided on a floor surface 2 along a longitudinal axis L. Further, two sets of seat units 10 and 15 are arranged along the passage 3 on both sides of the passage 3, thereby forming a seating arrangement. Curtains 5 are placed at both ends of the passageway 3 to separate it from adjacent compartments.

The seat unit 10 includes a seat 11a disposed on the aisle 3 side of the aircraft 1, a seat 11 including a backrest 11b disposed on the window 4 side, and a seat 11 provided side by side with the seat 11 and disposed on the aisle 3 side. It has a seat 12 including a seat 12a and a backrest 12b arranged on the window 4 side, a partition plate unit 13, and a cabinet (boundary part) 14 arranged between the seats 11, 12 and the aisle 3. . However, the boundary part is not limited to the cabinet 14 that stores articles, but may be a simple wall, for example.

The cabinet 14 is arranged on the side of the passage 3, facing the seats 11 and 12. Moreover, a passage 3 is formed between the cabinets 14 arranged in the width direction of the aircraft 1. The seat unit 10 is fixed to the floor surface 2.

The seat unit 15 is arranged on both sides of the aircraft 1 in the longitudinal direction with respect to the seat unit 10 installed side by side. The seat unit 15 includes a seat 16a arranged on the aisle 3 side of the aircraft 1, a seat 16 including a backrest 16b arranged on the window 4 side, a partition plate unit 17, and a space between the seat 16 and the aisle 3. It has a cabinet (boundary part) 18 arranged in the area. The seat unit 15 is also fixed to the floor surface 2. The partition plate unit 17 on one side of the passage 3 may be formed integrally with the partition plate unit 13 on the same side.

The cabinet 18 is arranged to face the seat 16, and the length of the cabinet 18 in the longitudinal direction of the aircraft 1 is approximately half the length of the cabinet 14.

Here, attention will be paid to the seat unit 10 on the front side of the aircraft 1. As shown in FIG. 1, when viewed along the direction perpendicular to the floor surface 2 of the aircraft 1, the central axis X1 of the seat (first seat) 11 and the central axis X2 of the seat (second seat) 12 is angled on the opposite side (front side and rear side) with respect to the orthogonal line (first orthogonal line) O1 orthogonal to the longitudinal direction axis L, and is oriented toward the central axis X1 of the seat 11 and the center axis X1 of the seat 12. It intersects with the central axis X2 at a point P1 on the passage 3 side (front side of the seat). Furthermore, if the midpoint between the part of the seat 11 closest to the passage 3 and the part of the seat 12 closest to the passage 3 (referred to as the proximate midpoint) is Q1, the orthogonal line O1 passes through the proximate midpoint Q1. .

Furthermore, the central axis X2 of the seat (second seat) 12 of the front seat unit 10 and the central axis X3 of the seat (third seat) 11 of the rear seat unit 10 adjacent thereto are The central axis X2 of the seat 12 and the central axis X3 of the seat 11 are angled to the opposite side (front side and rearward side) with respect to the orthogonal line (second orthogonal line) O2 orthogonal to the axis L. Intersect at point P2 on the window 4 side. Further, if the proximity intermediate point between the portion of the seat 12 closest to the passage 3 and the portion of the seat 11 closest to the passage 3 is defined as Q2, the orthogonal line O2 passes through the proximity intermediate point Q2.

When a plurality of seat units 10 are arranged in the longitudinal direction of the aircraft 1, the above-described relationship between the center axes can occur between any of the seat units 10, or between the seat units 10 and 15.

Here, the central axis of the seat refers to a straight line that passes through the center point (center of gravity) of the seat and the center point (center of gravity) of the backrest and goes from the backrest side to the seat side, as seen in FIG. The intersection angle between the central axes is preferably 90 degrees or less, more preferably 60 degrees or less, and even more preferably 30 degrees ± 10 degrees.

According to this embodiment, the central axis X2 of the seat 12 and the central axis X3 of the seat 11, which are adjacent to each other across the boundary between the two seat units 10, are angled so as to be separated from each other as they move toward the aisle side. Therefore, a passenger sitting on the seat 11 and a passenger sitting on the seat 12 can access the passage 3 through the space (entrance/exit) 7 between adjacent cabinets 14 without interfering with each other. Note that the space between the space 7 and the boundary between adjacent seat units 10 is defined as an access area.

2 and 3 are perspective views of the seat unit 10 viewed from the aisle side, and FIGS. 4 and 5 are perspective views of the seat unit 10 viewed from the window side.

The partition plate unit 13 includes a rear wall 13a arranged behind the seats 11 and 12, an intermediate partition plate 13b arranged between the seats 11 and 12, and a first side wall 13a arranged adjacent to the seats 11. A partition plate 13c and a second side partition plate 13d arranged adjacent to the seat 12 are integrally arranged in series. That is, the rear wall 13a, the intermediate partition plate 13b, the first side partition plate 13c, and the second side partition plate 13d form a substantially E-shaped partition plate unit 13 when viewed in the direction of FIG. ing. Further, the length of the intermediate partition plate 13b along the orthogonal lines O1 and O2 is shorter than the length of the side partition plates 13c and 13d.

As shown in FIG. 1, in the longitudinal direction of the aircraft 1, the orthogonal line O1 passing through the nearby intermediate point Q1 and the intermediate partition plate 13b overlap with the cabinet 14; The partition plates 13c, 13d and the cabinet 14 do not overlap. Preferably, the orthogonal line O2 passes through a midpoint between cabinets 14 that are adjacent to each other in the longitudinal direction of the aircraft 1. Further, when viewed along the longitudinal direction axis L, the intermediate partition plate 13b and the side partition plates 13c, 13d and the cabinet 14 are spaced apart from each other so that passengers can pass between them. An armrest 13g or the like can be arranged between the seats 11, 12 and the side partition plates 13c, 13d. The height of the partition plate unit 13 from the floor surface 2 is preferably higher than the line of sight of passengers sitting on the seats 11 and 12. However, as shown in a modification described later, instead of providing the partition plate unit, a structure that blocks the line of sight of passengers may be provided.

When strangers sit on the seats 11 and 12 of the same seat unit 10, their private space is secured by the intermediate partition plate 13b. Furthermore, when strangers sit on adjacent seats 12 and 11 of adjacent seat units 10, a private space for each other is secured by the side partition plates 13c or 13d.

Note that, referring to FIG. 1, the partition plate unit 17 includes a rear wall 17a and side partition plates 17b arranged on both sides of the seat 16. The configuration of the partition plate unit 17 is almost the same as the partition plate unit 13 except that it does not have an intermediate partition plate.

A plurality of cabinets 14 arranged side by side along the passageway 3 have legs 14a fixed to the floor 2, a casing 14b supported by the legs 14a, and are pivotable with respect to the casing 14b. It has an upper lid part 14c and a lower lid part 14d arranged. As shown in FIG. 3, by opening the upper lid part 14c and the lower lid part 14d, luggage and the like can be stored in the housing part 14b. On the other hand, by closing the upper lid part 14c and the lower lid part 14d as shown in FIG. 2, it is possible to prevent the cargo from accidentally falling. Note that the lid may be a single lid, or the lid may be opened and closed not only on the aisle side but also on the seat side or on the longitudinal side of the aircraft.

As shown in FIGS. 4 and 5, the leg portion 14a has an opening on the seat 11 and 12 sides, and an intermediate support portion 14e that supports the bottom wall of the housing portion 14b against the floor is located at the center of the opening. is located. Shelves 14f are arranged parallel to the floor 2 on both sides of the intermediate support part 14e, and both ends of the shelves are fixed to the legs 14a and the intermediate support part 14e, so that passengers can place bags and the like on the shelves 14f. I am making it possible to place it.

Passengers sitting on the seats 11 and 12 can insert their legs into the opening of the leg section 14a below the shelf 14f, and by stretching their legs, they can enjoy a comfortable flight even for a long time. Note that an ottoman may be provided on the leg portion 14a instead of the shelf 14f.

A display 19 is arranged on mounting surfaces 14h, 14h of the housing portion 14b on the seats 11, 12 side. The mounting surfaces 14h and 14h of the casing portion 14b to which the display 19 is attached are inclined with respect to the longitudinal axis L (see FIG. 1) in accordance with the seats 11 and 12 whose central axes are inclined, respectively. This allows passengers sitting on the seats 11 and 12 to view the image displayed on the display 19 from approximately the front.

Further, below the display 19, a table 20 that can be accommodated within the housing portion 14b is arranged. As shown in FIG. 5, by pulling out the table 20 from the housing portion 14b, passengers sitting on the seats 11 and 12 can eat and drink with drinks and food placed on the table 20. Even when the table 20 is pulled out, passengers can easily access the aisle 3 through the space 7. Further, since the space 7 can be commonly used by passengers sitting on the seats 11 and 12 sandwiching it, the space can be used effectively.

Further, as shown in FIG. 4, by pushing the table 20 into the housing portion 14b and storing it, the passengers sitting on the seats 11 and 12 can take a relaxed posture.

Note that the configuration of the cabinet 18 is substantially the same as that of the cabinet 14, except that it does not have an intermediate support portion and has a single shelf 14f.

(First modification)
FIG. 6 is a perspective view of the seat unit 10A according to the first modification as viewed from the window side. This modification differs from the embodiment described above only in the configuration of the housing portion 14Ab of the cabinet 14A. Specifically, the housing portion 14Ab has a bottomed rectangular tube shape with an open top, and a bassinet 14Ag in which an infant or the like can be placed is formed inside. The housing portion 14Ab does not have an openable/closeable lid. The other configurations (leg portions 14a, etc.) are the same as those in the above-described embodiment, and therefore redundant explanation will be omitted.

(Second modification)
FIG. 7 is a perspective view of a seat unit 10B according to a second modification as viewed from the aisle side, with the cabinet omitted. In this modification, the shape of the partition plate unit 13B is different from the embodiment shown in FIG. 2. More specifically, the partition plate unit 13B does not have a rear wall or a side partition plate, but only has an intermediate partition plate 13Bb arranged between the sheets 11 and 12. The other configurations are the same as those in the embodiment described above, and therefore redundant explanation will be omitted.

(Third modification)
FIG. 8 is a perspective view of a seat unit 10C according to a third modification as viewed from the aisle side, with the cabinet omitted. In contrast to the embodiment shown in FIG. 2, in this modification, no partition plate unit is provided, and instead, a blind unit 13C is provided for each sheet. Specifically, the blind unit 13C is formed by connecting a back panel 13Ca and side panels 13Cb and 13Cc extending in parallel from both ends of the back panel 13Ca in a C-shape.

When the back panels 13Ca are attached to the backs of the headrests 11c and 12c arranged at the upper ends of the backrests 11b and 12b of the seats 11 and 12, respectively, the side panels 13Cb and 13Cc are attached to the front sides of the headrests 11c and 12c from both sides. protrude to. Since the line of sight of the passengers seated on the seat 11 or the seat 12 is blocked by the side panels 13Cb and 13Cc, privacy can be ensured. For example, speakers connected to AV equipment mounted on the aircraft may be provided on the side panels 13Cb and 13Cc.

In addition, various modifications can be made to the above embodiments without departing from the gist of the present invention.
