MODE FOR CARRYING OUT THE INVENTION

[0027] Hereafter, embodiments of the present embodiment will be illustrated with reference to the drawings. In the present specification, frontward and rearward respectively refer to a travelling direction of the aircraft and a direction opposite to the travelling direction. A seat unit 10 according to the present embodiment may be utilized as a seat unit for a business class cabin, for example.

First Embodiment

[0028] FIG. 1 is a top view overlooking a cabin of an aircraft 1 (viewed in a direction perpendicular to a floor surface 2 of the aircraft 1) in which seat units for an aircraft according to a first embodiment are installed. In FIG. 1, a left side is a head side of the aircraft 1, a right side is a rear side of the aircraft 1, and a front-rear direction axis of the aircraft 1 is denoted by L. An aisle 3 is disposed on the floor surface 2 of the aircraft 1 along the front-rear direction axis L. Further, five sets of seat units 10 are arranged on either side of and interposing the aisle 3 (10 sets in total) disposed along the aisle 3. The seat unit 10 has a symmetric arrangement and shape interposing the front-rear direction axis L. A curtain 5 is arranged on either end of the aisle 3 in order to partition the section from adjacent sections.

[0029] The seat unit 10 includes a seat 11 equipped with a seat section 11a disposed on a window 4 side of the aircraft 1 and a backrest 11b disposed on the aisle 3 side, a table 12 arranged between the window 4 and the seat section 11a, and a partition panel 13 disposed on a side portion of the seat 11. The seat 11 and the partition panel 13 are fixed to the floor surface 2.

[0030] The seat unit 10 forms a set with the partition panel 13 on the left hand side of a passenger seated on the seat 11, and since five seats 11 are arranged in a row along the front-rear direction of the aircraft 1, the seat 11 is arranged in a manner sandwiched between its own partition panel 13 (that constitutes a set of the seat unit 10 with the seat 11) and a partition panel 13 of the adjacent seat unit 10. However, the seat 11 disposed on the most frontward side of the aircraft 1 is arranged in a manner sandwiched between its own partition panel 13 and a front side wall 6. Nevertheless, the seat unit 10 may form a set with the partition panel 13 on a right hand side of the passenger seated on the seat 11.

[0031] A width of the seat 11 is made smaller than a distance between partition panels 13 interposing the seat 11, and a center of the seat 11 is either arranged in a shifted manner toward a rearward (or frontward) side of the aircraft 1 from an intermediate position of the partition panels 13 interposing the same or arranged at a center between the partition panels 13. Therefore, the seat 11 and its own partition panel 13 are in contact with each other, and a space 7 through which the passenger may access the aisle 3 is formed between the seat 11 and the partition panel 13 disposed adjacent thereto on the frontward side (or rearward side) of the aircraft 1.

[0032] As illustrated in FIG. 1, when viewed along a direction orthogonal to the floor surface 2 of the aircraft 1, a center axis X of the respective seats 11 is approximately orthogonal to the front-rear direction axis L, and the partition panel 13 extends in parallel to the center axis X. Here, the center axis X of the seat 11 refers to a straight line passing through a center point (center of gravity point) of the seat section 11a and the center point (center of gravity point) of the backrest 11b as illustrated in FIG. 1. Further, approximately orthogonal refers to a state in which it intersects the axis in the front-rear direction of the aircraft at an angle of 90 degrees5 degrees.

[0033] According to the present embodiment, the number of seats 11 being interposed between the partition panels 13 is one, such that a large number of seat units 10 may be arranged efficiently within the aircraft even though a private space of each passenger seated on the seat 11 may be ensured. Further, the passenger seated on the seat 11 may access the aisle 3 freely through the space 7 without interfering other passengers. Furthermore, since the line of sight of the passenger seated on the seat 11 is directed toward the window 4, there is an advantage in that the passenger seated on the seat 11 will not be disturbed by passengers and crew members walking on the aisle 3 arranged behind the seat 11.

[0034] FIGS. 2 and 3 are views illustrating the seat unit 10 from the aisle side over the seat 11. FIG. 4 is a perspective view illustrating the seat unit 10, indicating a state where a passenger is seated. FIG. 5 is a view in which the partition panel 13 disposed adjacent to the seat unit 10 of FIG. 4 is viewed from the side of the seat 11 of FIG. 4.

[0035] An engagement long hole 13a that extends in parallel to the floor surface 2 and a slit groove 13b arranged adjacent thereto are formed on a wall (or a front side wall 6) on one side (left side in the drawing) of the partition panel 13 (refer to FIG. 5). Further, a frame 13g fixed to the seat 11 extends from a side portion of the seat 11 toward the window side at a position adjacent to the other wall (right side in the drawing) of the partition panel 13. An engagement long hole 13c that extends in parallel to the floor surface 2 and a slit groove 13d (refer to FIG. 4) arranged adjacent thereto are formed on the frame 13g. The slit grooves 13b and 13d are formed longer than the engagement long holes 13a and 13c. The heights from the floor surface 2 and the lengths of engagement long holes 13a and 13c and the slit grooves 13b and 13d arranged facing each other mutually correspond. The frame 13g may be fixed independently on the floor surface 2 without being fixed to the seat 11.

[0036] In FIG. 4, the table (also referred to as table unit) 12 includes a fixed portion 12a having a rectangular plate shape, and a movable portion 12b having a rectangular plate shape, which are formed somewhat longer than a distance between the partition panel 13 and the frame 13g. Both ends in the longitudinal direction of the fixed portion 12a (both ends in the center axis X direction: two points that are spaced apart in the width direction) are engaged to the engagement long holes 13a and 13c, by which both ends of the fixed portion 12a are fixed to the partition panel 13. Thereby, the table 12 which is simple and light-weight yet having a high rigidity may be realized. The fixed portion 12a may also be fixed to the partition panel 13 via a bracket.

[0037] Further, both ends in the longitudinal direction of the movable portion 12b are engaged slidably to the slit grooves 13b and 13d. Therefore, the movable portion 12b may slide arbitrarily between a stored position illustrated in FIG. 4(a) and a drawn-out position illustrated in FIG. 4(b). For example, when a passenger PA being seated on the seat 11 eats or drinks, the passenger PA draws out the movable portion 12b to the drawn-out position illustrated in FIG. 4(b) to place drinks and foods on the fixed portion 12a and the movable portion 12b which ensure a large area. Meanwhile, when the passenger PA finishes his/her meal, the passenger PA returns the movable portion 12b to the stored position illustrated in FIG. 4(a), such that the passenger PA may take a relaxed posture, and will not be obstructed when heading toward the aisle 3 through the space 7.

[0038] As illustrated in FIGS. 2 and 3, a screen unit 15 is disposed above the table 12 in a manner connecting top portions of the partition panels 13. A screen 15a (refer to FIG. 3) is disposed within the screen unit 15, and normally, the screen is stored in a manner wound up in the screen unit 15, as illustrated in FIG. 2. Therefore, the passenger seated on the seat 11 may enjoy the outside view of the aircraft through the window 4.

[0039] In contrast, as illustrated in FIG. 3, the screen 15a may be drawn out of the screen unit 15, as illustrated in FIG. 3, and a hook (not shown) disposed at a center or at both ends of a lower end of the screen 15a may be hooked onto the table 12 and retained thereon (refer to FIG. 3). Thereby, the screen 15a is perpendicularly disposed in a stretched manner on the table 12, such that the passenger seated on the seat 11 may view from the front side images and videos projected on the screen 15a from a portable projector that the passenger carries or a projector installed within the fuselage (not shown). However, the method for disposing the screen 15a in a stretched manner is not limited to the above.

[0040] FIGS. 6 and 7 are perspective views illustrating a lower side of the table 12. With reference to FIGS. 4 and 6, an intermediate panel 12c is joined to an edge of the window 4 side of the fixed portion 12a of the table 12 excluding both ends thereof. A lower end of the intermediate panel 12c is connected to an edge on the window 4 side of a footrest panel 12d formed in a rectangular plate shape. That is, the fixed portion 12a, the intermediate panel 12c, and the footrest panel 12d are formed in an approximately C-shape when viewed in the direction of the front-rear direction axis L. When engaging the fixed portion 12a to the engagement long holes 13a and 13c of the partition panel 13, by abutting the end portion of the intermediate panel 12c against the partition panel 13, the partition panel 13 may function as a stopper indicating the appropriate assembling position. Further, the footrest panel 12d may be fixed to the partition panel 13 by engaging the longitudinal ends thereof to engagement long holes provided on the partition panel 13.

[0041] The passenger PA seated on the seat 11 may place the feet of his/her legs LG on the footrest panel 12d disposed on the lower side of the table 12, as illustrated in FIG. 7, and thereby, the passenger PA may enjoy a pleasant flight which may take a long time.

First Modified Example

[0042] FIG. 8 is a perspective view illustrating a lower side of the table 12 according to a first modified example. In the present modified example, an intermediate panel and a footrest panel are not disposed, and instead, an ottoman 16 is disposed. The ottoman 16 has a long plate shape which extends along the front-rear direction axis L, and on an upper surface thereof is disposed an artificial leather and a cushion member. The ottoman 16 is fixed to the partition panel 13 by having its longitudinal ends engaged to engagement long holes 13f (only one of which is illustrated) disposed on the partition panels 13. However, the ottoman 16 may also be fixed by connecting the same to the fixed portion 12a of the table 12.

[0043] The passenger PA seated on the seat 11 may place his/her calves and thigh portions of his/her leg portions LG on the ottoman 16 disposed on the lower side of the table 12, such that the passenger PA may enjoy a pleasant flight which may take a long time.

[0044] Further, a rack on which a bag may be placed may be formed in a manner fixed to the fixed portion 12a of the table 12 or the partition wall 13 on the lower side of the table 12.

Second Modified Example

[0045] FIG. 9 is a perspective view illustrating a periphery of a table 12 according to a second modified example. In the present modified example, a bassinet unit 17 having a bottomed rectangular tubular shape is fixed to a left side partition panel 13 in FIG. 9. A bassinet 17a on which an infant may be laid is formed on an upper portion of the bassinet unit 17. A gap through which a passenger walking toward the aisle 3 may easily pass is formed between the bassinet unit 17 and the seat 11. The bassinet unit 17 constitutes a member that supports one end portion in the width direction of the table 12.

[0046] A left end of the fixed portion 12a of the table 12 is fixed to the bassinet unit 17, and a right end of the fixed portion 12a is engaged to the engagement long hole 13c of the partition panel 13 disposed on the right side, by which both ends of the fixed portion 12a are fixed. Further, a left end of the movable portion 12b is engaged slidably to a slit groove 17b of the bassinet unit 17, and a right end of the movable portion 12b is engaged to the slit groove 13d of the partition panel 13 disposed on the right side, by which both ends of the movable portion 12b are retained in a slidable manner.

Second Embodiment

[0047] FIG. 10 is a view of a seat unit 10A according to a second embodiment taken from an aisle side over the seat, with the windows not shown. Compared to the embodiment illustrated in FIG. 2, the seat unit 10A according to the present embodiment is not equipped with a frame. Instead, an engagement long hole 13Ac and a slit groove 13Ad adjacent thereto are formed on a partition wall 13A disposed on a right side in the drawing. The heights from the floor surface 2 and the lengths of the engagement long holes 13a an 13Ac and the slit grooves 13b and 13Ad arranged facing each other mutually correspond. That is, in a case where the table 12 is arranged on both sides interposing the partition wall 13A, the engagement long holes 13a and 13Ac and the slit grooves 13b and 13Ad are formed facing both side surfaces of the partition wall 13A. Configurations other than those described above will not be described, since they are similar to the above-described embodiments.

[0048] Even according to the present embodiment, longitudinal end portions of the fixed portion 12a of the table 12 are engaged to the engagement long holes 13a and 13Ac, by which both ends of the fixed portion 12a are fixed to the partition panels 13 and 13A. Further, both ends of the movable portion 12b in the longitudinal direction are engaged slidably to the slit grooves 13b and 13Ad. Thereby, the movable portion 12b is enabled to move relatively with respect to the fixed portion 12a.

[0049] Various modifications of the above embodiments are enabled within the range not deviating from the scope of the present invention.
