Description

[Technical field]

[0001] The present invention relates to a seat unit and a table unit. [Background technology]

[0002] Conventional aircraft used for relatively short-distance flights of around three to six hours tend to be small, with a single aisle located in the center of the aircraft along the aircraft's longitudinal axis, and two rows of forward-facing seats arranged on either side of the aisle.

[0003] In such aircraft, for example, movable tables are often used as dining tables, such as a type that is swayably installed on the backrest of the front seat and can be swayed into a horizontal position, or a type that is folded and stored within the armrest of the seat and can be pulled out for use, thereby making effective use of space.

[0004] In the case of such movable tables, the table is often supported at one end by links or the like, but in order to ensure stable support, it is necessary to increase the size and rigidity of the movable mechanisms such as the links and connecting parts, which may result in an increase in installation space and an increase in the weight of the entire table. Therefore, it is difficult to adopt a table with such a large movable mechanism, especially in an aircraft with a small body.

[0005] In addition, if a passenger sitting in an aisle seat uses a movable table, a passenger sitting in a window seat must temporarily move the table when trying to access the aisle, which is inconvenient. For short flights, passenger complaints are relatively rare, but in recent years, the range of aircraft has improved due to improvements in fuel efficiency technology. For this reason, as flight times become longer, passenger complaints that have been suppressed up until now may become more apparent.

[0006] In contrast, the passenger suite disclosed in Patent Document 1 has a single seat unit equipped with a seat facing the fore-and-aft direction of the aircraft, a seat facing the window, and a pull-out table, so that even when the table is pulled out, there is good access to the aisle from all seats.

[0007] [Patent Document 1] Special Publication No. 2015-512823 Summary of the Invention [Problem to be solved by the invention]

[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 is applied to aircraft for short-haul flights, it will occupy a lot of space, resulting in a problem of a significant reduction in the number of passengers that can board. In addition, the seats facing the front and rear of the aircraft and the seats facing the windows are not designed for other people to sit in, so if two people were to use the passenger suite disclosed in Patent Document 1, they would be unable to ensure private space.

[0014] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In this specification, the terms "forward" and "rearward" 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 as a seat unit for business class, for example.

[0015] (First embodiment) FIG. 1 is a top view (seen vertically to a floor surface 2 of the aircraft 1) showing an overhead view of a cabin of an aircraft 1 equipped with an aircraft seat unit according to a first embodiment. In FIG. 1, the left side is the front 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, an aisle 3 is arranged on the floor surface 2 along the longitudinal axis L. Furthermore, five sets of seat units 10 (a total of ten sets) are arranged along the aisle 3 on both sides of the aisle 3. The seat units 10 are arranged and shaped symmetrically with respect to the longitudinal axis L. 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 window 4 side of the aircraft 1 and a backrest 11b arranged on the aisle 3 side, a table 12 arranged between the window 4 and the seat 11a, and a partition board 13 arranged on the side of the seat 11. The seat 11 and the partition board 13 are fixed to the floor surface 2.

[0017] The seat unit 10 is set with a partition board 13 on the left hand side of a passenger sitting in the seat 11, but since five seats 11 are arranged in a row along the longitudinal direction of the aircraft 1, each seat 11 is sandwiched between its own partition board 13 (which constitutes a set of the seat 11 and the seat unit 10) and the partition board 13 of the adjacent seat unit 10. However, the seat 11 located at the frontmost side of the aircraft 1 is sandwiched between its own partition board 13 and the front wall 6. Without being limited to the above, the seat unit 10 may be set with a partition board 13 on the right hand side of a passenger sitting in the seat 11.

[0018] The width of the seat 11 is smaller than the distance between the partitions 13 that sandwich it, and the center of the seat 11 is shifted toward the rear (or front) of the aircraft 1 with respect to the intermediate position of the partitions 13 that sandwich it, or is located in the center between the partitions 13. Therefore, the seat 11 and its own partition 13 are in contact, and a space 7 that allows passengers to access the aisle 3 is formed between the seat 11 and the partition 13 adjacent to it on the front (or rear) side of the aircraft 1.

[0019] When viewed along a direction perpendicular to the floor 2 of the aircraft 1 as shown in Fig. 1, the central axis X of each seat 11 is substantially perpendicular to the longitudinal axis L, and the partition plate 13 extends parallel to the central axis X. Here, the central axis X of the seat 11 refers to a straight line passing through the center point (center of gravity) of the seat 11a and the center point (center of gravity) of the backrest 11b as viewed in Fig. 1. Moreover, "substantially perpendicular" means that it intersects with the longitudinal axis of the aircraft at an angle of 90 degrees ±5 degrees.

[0020] According to this embodiment, since there is only one seat 11 sandwiched between the partitions 13, many seat units 10 can be efficiently arranged inside the aircraft while ensuring private space for passengers sitting in each seat 11. In addition, passengers sitting in the seats 11 can freely access the aisle 3 through the space 7 without interfering with other passengers. Furthermore, since the line of sight of the passengers sitting in the seats 11 faces the window 4, there is also the advantage that the passengers sitting in the seats 11 are not bothered by passengers or crew members passing through the aisle 3 behind them.

[0021] 2 and 3 are views of the seat unit 10 seen from the aisle side through the seat 11. Fig. 4 is a perspective view of the seat unit 10 with a passenger seated. Fig. 5 is a view of the partition plate 13 adjacent to the seat unit 10 in Fig. 4 seen from the seat 11 side in Fig. 4.

[0022] An engagement slot 13a and an adjacent slit groove 13b are formed in one wall (left side in the figure) of the partition plate 13 (or the front wall 6) extending parallel to the floor surface 2 (see FIG. 5). A frame 13g fixed to the sheet 11 is adjacent to the other wall (right side in the figure) of the partition plate 13 and extends from the side of the sheet 11 toward the window side. An engagement slot 13c and an adjacent slit groove 13d (see FIG. 4) are formed in the frame 13g extending parallel to the floor surface 2. The slit grooves 13b and 13d are formed longer than the engagement slots 13a and 13c. The heights and lengths from the floor surface 2 of the engagement slots 13a and 13c and the slit grooves 13b and 13d arranged opposite to each other are the same. The frame 13g may be fixed independently to the floor surface 2 without being fixed to the sheet 11.

[0023] In Fig. 4, the table (also called a table unit) 12 has a rectangular plate-shaped fixed part 12a and a rectangular plate-shaped movable part 12b, which are formed slightly longer than the distance between the partition plate 13 and the frame 13g. Both ends in the longitudinal direction of the fixed part 12a (both ends in the direction of the central axis X: two points spaced apart in the width direction) are engaged with the engagement slots 13a and 13c, whereby both ends of the fixed part 12a are fixed to the partition plate 13. This makes it possible to realize a simple, lightweight, yet highly rigid table 12. The fixed part 12a can also be fixed to the partition plate 13 by a bracket or the like.

[0024] In addition, both ends of the movable part 12b in the longitudinal direction are slidably engaged with the slit grooves 13b and 13d. Therefore, the movable part 12b can be slid between the stored position shown in FIG. 4(a) and the drawn-out position shown in FIG. 4(b). For example, when the passenger PA sitting on the seat 11 eats or drinks, the passenger PA can draw out the movable part 12b to the drawn-out position shown in FIG. 4(b) and place drinks or food on the fixed part 12a and the movable part 12b, which have a large area. On the other hand, when the passenger PA finishes eating, the passenger PA can take a relaxed posture by returning the movable part 12b to the stored position shown in FIG. 4(a), and is not prevented from moving toward the aisle 3 through the space 7.

[0025] As shown in Figures 2 and 3, a screen unit 15 is disposed above the table 12 so as to connect the upper part of the partition plate 13. A screen 15a (see Figure 3) is disposed within the screen unit 15, and is usually stored in a rolled-up state within the screen unit 15 as shown in Figure 2. This allows passengers seated in the seats 11 to view the outside of the aircraft through the windows 4.

[0026] 3, the screen 15a can be pulled out from the screen unit 15 and held by hooking hooks (not shown) provided at the center of the bottom end or at both ends onto the table 12 (see FIG. 3). This allows the screen 15a to be stretched vertically above the table 12, and passengers sitting in the seats 11 can view images and videos projected onto the screen 15a from a portable projector brought by the passenger or a projector (not shown) installed in the cabin from the front. However, the method of stretching the screen 15a is not limited to the above.

[0027] 6 and 7 are perspective views showing the lower part of the table 12. Referring to FIGS. 4 and 6, the intermediate plate 12c is joined to the edge of the fixed part 12a of the table 12 on the window 4 side except for both ends. The lower end of the intermediate plate 12c is connected to the edge of the footrest plate 12d, which is a rectangular plate, on the window 4 side. That is, the fixed part 12a, the intermediate plate 12c, and the footrest plate 12d are substantially C-shaped when viewed in the direction of the front-rear axis L. Here, when the fixed part 12a is engaged with the engagement elongated holes 13a and 13c of the partition plate 13, the ends of the intermediate plate 12c can be abutted against the partition plate 13 to function as a stopper indicating an appropriate assembly position. The footrest plate 12d may be fixed to the partition plate 13 by engaging both longitudinal ends of the footrest plate 12d with the engagement elongated holes provided in the partition plate 13.

[0028] As shown in FIG. 7, a passenger PA sitting in the seat 11 can place the soles of his / her feet LG on the footrest board 12d located below the table 12, thereby enabling the passenger PA to enjoy a comfortable flight even for long periods of time.

[0029] (First Modification) 8 is a perspective view showing the lower part of the table 12 according to the first modified example. In this modified example, an intermediate plate and a footrest plate are not provided, and instead an ottoman 16 is provided. The ottoman 16 is a long and narrow plate in the direction of the front-rear axis L, and artificial leather and a cushioning material are provided on the upper surface of the ottoman 16. The ottoman 16 is fixed to the partition plate 13 by engaging both ends in the longitudinal direction with elongated engagement holes 13f (only one side is shown) provided in the partition plate 13. However, the ottoman 16 may be fixed by connecting it to the fixed part 12a of the table 12.

[0030] The ottoman 16 arranged below the table 12 allows the passenger PA sitting in the seat 11 to rest the calves and thighs of the legs LG, thereby enabling the passenger PA to enjoy a comfortable flight even during long flights.

[0031] A shelf on which bags or the like can be placed may be formed below table 12 and fixed to fixed portion 12a of table 12 or partition plate 13.

[0032] (Second Modification) Fig. 9 is a perspective view showing the periphery of a table 12' according to a second modified example. In this modified example, a bassinet unit 17 in the shape of a rectangular cylinder with a bottom is fixed to the partition plate 13' on the left side in Fig. 9. A bassinet 17a on which an infant or the like can be laid is formed on the upper part of the bassinet unit 17. Between the bassinet unit 17 and the seat 11, there is a gap through which passengers heading towards the aisle 3 can easily pass. The bassinet unit 17 constitutes a member supporting one widthwise end of the table 12'.

[0033] The left end of the fixed part 12a' of the table 12' is fixed to the bassinet unit 17, and the right end of the fixed part 12a' engages with the engagement slot 13c of the right-side partition plate 13, thereby fixing both ends of the fixed part 12a'. The left end of the movable part 12b' slidably engages with the slit groove 17b of the bassinet unit 17, and the right end of the movable part 12b' engages with the slit groove 13d of the right-side partition plate 13, thereby holding both ends of the movable part 12b' slidably.

[0034] Second embodiment FIG. 10 is a view of the seat unit 10A according to the second embodiment seen from the aisle side through the seat, with windows and the like omitted. Unlike the embodiment shown in FIG. 2, the seat unit 10A of this embodiment does not have a frame. Instead, an engagement slot 13Ac and an adjacent slit groove 13Ad are formed in the partition wall 13A on the right side in the figure. The heights and lengths from the floor surface 2 of the engagement slots 13a, 13Ac and the slit grooves 13b, 13Ad arranged opposite each other are the same. In other words, when the tables 12 are arranged on both sides of the partition wall 13A, the engagement slots 13a, 13Ac and the slit grooves 13b, 13Ad are formed opposite both side surfaces of the partition wall 13A. The other configurations are the same as those of the above-mentioned embodiment, so repeated explanations will be omitted.

[0035] In this embodiment, both ends of the fixed part 12a of the table 12 in the longitudinal direction are engaged with the engagement slots 13a and 13Ac, and thus both ends of the fixed part 12a are fixed to the partition plates 13 and 13A. Also, both ends of the movable part 12b in the longitudinal direction are slidably engaged with the slit grooves 13b and 13Ad. This allows the movable part 12b to move relative to the fixed part 12a.

[0036] In addition, various modifications can be made to the above-described embodiment without departing from the spirit and scope of the present invention. [Explanation of symbols]
