Description

[Technical Field]

[0001] The present invention is a seat unit. tt Regarding. [Background technology]

[0002] Generally, aircraft used for medium- to long-distance flights are relatively large, so they have multiple aisles and can be equipped with business seats called full-flat seats, which allow passengers to lie down and rest even on long flights.

[0003] In contrast, aircraft used for relatively short flights of around three to six hours tend to be smaller, with a single aisle located in the center of the aircraft along the longitudinal axis, and forward-facing seats arranged in double rows on either side of the aisle.

[0004] While business seats on smaller aircraft offer more front-to-back space and are wider than economy seats, they still lack sufficient legroom. Furthermore, if a passenger sitting in a window seat wants to access the aisle, they must pass in front of the aisle seat passenger, which can unintentionally wake the aisle passenger, creating an awkward experience for both parties. However, on short flights, passenger complaints about aisle access are relatively rare.

[0005] However, as the range of aircraft has increased in recent years due to improvements in fuel efficiency and other factors, passenger dissatisfaction may become more apparent as flight times become longer. For this reason, there is an urgent need to develop seat units for aircraft used for short-distance flights that are just as comfortable as those used for medium- to long-distance flights.

[0006] In contrast, the passenger suite disclosed in Patent Document 1 has a single seat unit containing both a seat facing the front and rear of the aircraft and a seat facing the window, ensuring good aisle access from both seats. [Prior art documents] [Patent documents]

[0008] However, the passenger suite disclosed in Patent Document 1 is used in first class on aircraft for medium- to long-haul flights, and if it were applied to an aircraft for short-haul flights, it would consume a lot of interior space, resulting in a significant reduction in the number of passengers.In addition, the seats facing the front and rear of the aircraft and the seats facing the window are not designed to be occupied by other passengers, so if two people were to use the passenger suite disclosed in Patent Document 1, it would be difficult to maintain private space.

[0009] Therefore, the object of the present invention is to provide a seat unit that requires only a small installation space and allows passengers to enjoy a comfortable flight. tt The purpose is to provide [Means for solving the problem]

[0014] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In this specification, "forward" and "rear" refer to the direction in which the aircraft is traveling and the direction opposite to the direction of travel, respectively. The seat unit 10 of this embodiment can be used, for example, as a seat unit for business class.

[0015] FIG. 1 is a top view (viewed vertically from the floor of the aircraft) showing a cabin of an aircraft 1 equipped with an aircraft seat unit according to this embodiment. In FIG. 1, the left side of the figure is the front of the aircraft 1 and the right side is the rear of the aircraft 1, with the longitudinal axis of the aircraft 1 designated as L. In the aircraft 1, an aisle 3 is arranged on the floor 2 along the longitudinal axis L. Two sets of seat units 10, 15 are arranged along the aisle 3 on either side of the aisle 3, forming a seating arrangement. Curtains 5 are arranged on both ends of the aisle 3 to separate it from adjacent sections.

[0016] The seat unit 10 includes a seat 11 having a seat 11a arranged on the aisle 3 side of the aircraft 1 and a seat back 11b arranged on the window 4 side, a seat 12 having a seat 12a arranged adjacent to the seat 11 on the aisle 3 side and a seat back 12b arranged on the window 4 side, a partition unit 13, and a cabinet (boundary portion) 14 arranged between the seats 11, 12 and the aisle 3. However, the boundary portion is not limited to the cabinet 14 for storing items and may be, for example, a simple wall.

[0017] The cabinets 14 are arranged beside the aisle 3, facing the seats 11 and 12. The aisle 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.

[0018] The seat units 15 are arranged on both sides of the adjacent seat units 10 in the longitudinal direction of the aircraft 1. The seat unit 15 has a seat 16 equipped with a seat 16a arranged on the aisle 3 side of the aircraft 1 and a backrest 16b arranged on the window 4 side, a partition unit 17, and a cabinet (boundary portion) 18 arranged between the seat 16 and the aisle 3. The seat unit 15 is also fixed to the floor surface 2. The partition unit 17 on one side across the aisle 3 may be formed integrally with the partition unit 13 on the same side.

[0019] The cabinet 18 is disposed opposite 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.

[0020] Here, attention is focused on the seat unit 10 at the front of the aircraft 1. When viewed along a direction perpendicular to the floor surface 2 of the aircraft 1 as shown in Fig. 1, the central axis X1 of the seat (first seat) 11 and the central axis X2 of the seat (second seat) 12 are angled on opposite sides (forward and rearward) of an orthogonal line (first orthogonal line) O1 that is perpendicular to the longitudinal axis L, and the central axis X1 of the seat 11 and the central axis X2 of the seat 12 intersect at point P1 on the aisle 3 side (forward of the seats). Furthermore, if the midpoint (referred to as the proximity midpoint) between the portion of the seat 11 closest to the aisle 3 and the portion of the seat 12 closest to the aisle 3 is designated as Q1, then the orthogonal line O1 passes through the proximity midpoint Q1.

[0021] 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 adjacent rear seat unit 10 are angled on opposite sides (front and rear) of an orthogonal line (second orthogonal line) O2 that is perpendicular to the longitudinal axis L, and the central axis X2 of the seat 12 and the central axis X3 of the seat 11 intersect at point P2 on the window 4 side. Furthermore, if the proximity midpoint between the portion of the seat 12 closest to the aisle 3 and the portion of the seat 11 closest to the aisle 3 is defined as Q2, the orthogonal line O2 passes through the proximity midpoint Q2.

[0022] The above-mentioned central axis relationship can occur between any of the seat units 10 when multiple seat units 10 are lined up in the fore-and-aft direction of the aircraft 1, and can also occur between seat unit 10 and seat unit 15.

[0023] 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 extends from the backrest to the seat, as seen in Figure 1. The intersecting 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.

[0024] 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 two seat units 10, are angled so that they move farther apart toward the aisle, allowing passengers sitting in seats 11 and 12 to access the aisle 3 through the space (doorway) 7 between the adjacent cabinets 14 without interfering with each other. The area between the space 7 and the boundary between the adjacent seat units 10 is defined as an access area.

[0025] 2 and 3 are perspective views of the seat unit 10 as seen from the aisle side, and FIGS. 4 and 5 are perspective views of the seat unit 10 as seen from the window side.

[0026] Partition plate unit 13 is formed by integrally connecting rear wall 13a disposed behind seats 11 and 12, intermediate partition plate 13b disposed between seats 11 and 12, first side partition plate 13c disposed adjacent to seat 11, and second side partition plate 13d disposed adjacent to seat 12. That is, rear wall 13a, intermediate partition plate 13b, first side partition plate 13c, and second side partition plate 13d form partition plate unit 13 that is substantially E-shaped when viewed in the direction of FIG. 1. The length of intermediate partition plate 13b along orthogonal lines O1 and O2 is shorter than the lengths of side partition plates 13c and 13d.

[0027] As shown in FIG. 1 , in the longitudinal direction of the aircraft 1, the orthogonal line O1 passing through the proximity midpoint Q1 and the middle partition 13b overlap with the cabinet 14, but the orthogonal line O2 passing through the proximity midpoint Q2 and the side partitions 13c and 13d do not overlap with the cabinets 14. Preferably, the orthogonal line O2 passes through the midpoint between adjacent cabinets 14 in the longitudinal direction of the aircraft 1. Furthermore, when viewed along the longitudinal axis L, the middle partition 13b, the side partitions 13c and 13d, and the cabinets 14 are spaced apart to allow passengers to pass between them. Armrests 13g and other devices can be placed between the seats 11 and 12 and the side partitions 13c and 13d. The height of the partition unit 13 from the floor 2 is preferably higher than the eye level of passengers sitting in the seats 11 and 12. However, as shown in a modified example described below, instead of providing a partition unit, a structure that blocks the passenger's line of sight may be provided.

[0028] When two different people are seated in seats 11 and 12 of the same seat unit 10, the middle partition 13b ensures a mutual private space. When two different people are seated in adjacent seats 12 and 11 of adjacent seat units 10, the side partitions 13c and 13d ensure a mutual private space.

[0029] 1, the partition plate unit 17 is formed by connecting 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 that of the partition plate unit 13, except that it does not have an intermediate partition plate.

[0030] The cabinets 14, arranged in a row along the aisle 3, each have legs 14a fixed to the floor 2, a housing 14b supported by the legs 14a, and an upper cover 14c and a lower cover 14d pivotably arranged relative to the housing 14b. As shown in FIG. 3, by opening the upper cover 14c and the lower cover 14d, luggage and the like can be stored inside the housing 14b. On the other hand, by closing the upper cover 14c and the lower cover 14d as shown in FIG. 2, luggage can be prevented from accidentally falling. Note that a single cover may be provided, or the cover may be configured to be openable not only on the aisle side but also on the seat side or on the longitudinal side of the aircraft.

[0031] 4 and 5, the leg portion 14a is open on the side facing the seats 11 and 12, and an intermediate support portion 14e is disposed in the center of the opening to support the bottom wall of the housing portion 14b against the floor surface. On both sides of the intermediate support portion 14e, shelves 14f are disposed parallel to the floor surface 2, and both ends of the shelves 14f are fixed to the leg portion 14a and the intermediate support portion 14e, allowing passengers to place their bags and the like on the shelves 14f.

[0032] Passengers sitting in seats 11 and 12 can insert their legs into the opening in leg section 14a below shelf 14f, allowing them to stretch their legs and enjoy a comfortable flight even during long flights. Note that an ottoman may be provided in leg section 14a instead of shelf 14f.

[0033] A display 19 is disposed on mounting surfaces 14h, 14h of housing 14b on the side of seats 11, 12. Mounting surfaces 14h, 14h of housing 14b on which display 19 is mounted are tilted with respect to longitudinal axis L (see FIG. 1) in accordance with seats 11, 12 whose central axes are tilted, thereby allowing passengers sitting in seats 11, 12 to view the image displayed on display 19 from substantially the front.

[0034] In addition, a table 20 that can be stored in the housing part 14b is arranged below the display 19. As shown in Fig. 5, by pulling out the table 20 from the housing part 14b, passengers sitting in the seats 11 and 12 can place drinks and food on the table 20 and eat and drink. Even when the table 20 is pulled out, passengers can easily access the aisle 3 through the space 7. Furthermore, the space 7 can be shared by the passengers sitting in the seats 11 and 12 that are sandwiched between them, which allows for effective use of the space.

[0035] Furthermore, as shown in FIG. 4, by pushing the table 20 into the housing portion 14b and storing it therein, passengers sitting in the seats 11 and 12 can take a relaxed posture.

[0036] The configuration of the cabinet 18 is almost the same as that of the cabinet 14, except that the cabinet 18 does not have an intermediate support portion and has a single shelf 14f.

[0037] (First Modification) FIG. 6 is a perspective view of a seat unit 10A according to a first modified example, viewed from the window side. In this modified example, only the configuration of the housing portion 14Ab of the cabinet 14A is different from the embodiment described above. Specifically, the housing portion 14Ab is a rectangular cylinder with a closed bottom and an open top, and a bassinet 14Ag is formed inside in which a baby or the like can be laid. The housing portion 14Ab does not have an openable lid. The other configurations (leg portions 14a, etc.) are the same as those in the embodiment described above, so repeated explanations will be omitted.

[0038] (Second Modification) FIG. 7 is a perspective view of a seat unit 10B according to a second modified example, seen from the aisle side, with the cabinet omitted. In this modified example, the shape of the partition unit 13B is different from that of the embodiment shown in FIG. 2. More specifically, the partition unit 13B does not have a rear wall or side partitions, but only has an intermediate partition 13Bb disposed between the seats 11 and 12. Other configurations are the same as those in the above-described embodiment, and therefore, repeated explanations will be omitted.

[0039] (Third Modification) Fig. 8 is a perspective view of a seat unit 10C according to a third modified example, seen from the aisle side, with the cabinet omitted. Unlike the embodiment shown in Fig. 2, this modified example does not include a partition unit, but instead provides a blind unit 13C for each seat. Specifically, the blind unit 13C is configured by connecting a back panel 13Ca and side panels 13Cb and 13Cc extending parallel to each other from both ends of the back panel 13Ca in a C-shape.

[0040] When back panel 13Ca is attached to the backs of headrests 11c and 12c, which are disposed at the upper ends of backrests 11b and 12b of seats 11 and 12, respectively, side panels 13Cb and 13Cc protrude forward from both sides of headrests 11c and 12c. Passengers seated in seats 11 and 12 can maintain their privacy because their line of sight is blocked by side panels 13Cb and 13Cc. Speakers connected to onboard AV equipment, for example, may be disposed on side panels 13Cb and 13Cc.

[0041] In addition, various modifications can be made to the above-described embodiment without departing from the spirit of the present invention. [Explanation of symbols]
