Each of the seats 1A and 1B includes a seat bottom 2, an armrest 3, a seat back 4, a footrest 5, and a tilt device (not shown) for tilting the seat back 4 in the front-rear direction. In the case of aircraft seats, the seat pitch differs between a first class seat and a business class seat and an economy class seat. First class seats and business class seats have a wider seat pitch than the economy class seats in order to increase the distance between adjacent seats, and a central armrest that separates the two seats 1A and 1B. The width of 3a is set larger than the width of the two outer armrests 3b.

[0003]

As described above, in such a conventional double-seat type seat, in the case of a first-class seat or a business-class seat used in a cabin of an aircraft, a seat of an adjacent occupant is required. The seat pitch is widened to increase the gap, and the width of the armrest between the seats is set large.However, when sitting in an economy class seat with a narrow seat pitch, the shoulders and elbows of adjacent occupants may touch when sitting. If you turn your face to the next seat side, the face of the next occupant can be seen close up, so if strangers are sitting together, it is uncomfortable to sit , care and nervous, sit for a long time Being at home can be painful.

Accordingly, the present invention has been made in view of the above-mentioned conventional problems, and has as its object the following:
Shoulders and elbows do not touch without widening the seat pitch
It is an object of the present invention to provide a double-seat type seat that can improve sitting comfort and withstand long-time sitting.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings. FIG. 1 is a front view showing an embodiment in which the double seat type seat according to the present invention is applied to a three-seat seat, FIG. 2 is a side view of the seat, and FIG. 3 is a plan view of the seat. This embodiment is parallel to each other as is apparent from FIG.
The three seats 20 are configured by horizontally arranging three seats 1A, 1B, and 1C facing forward . Each of the seats 1A, 1B, and 1C is a tilting device (not shown) that tilts the seat bottom 2, the armrest 3, the seatback 4, the leg base 5, and the seatback 4 in the front-rear direction in the same manner as the above-described conventional two-seat seat. And so on. The seat bottom 2 and the seat back 4 include a frame member having rigidity similar to a general type of this type of seat, and cover this with a cushion material such as urethane or foam rubber with a fabric, a synthetic resin cover, leather or the like. It is formed by. The armrests 3 all have the same width. The backrest surfaces 11 of the seatbacks 4 of the seats 1A and 1C located at both ends are inclined at an angle α with respect to a surface 12 parallel to the direction in which the seats are arranged so as to face the outside of the three-seat seat 20. Is formed. For this reason, in FIG. 3, the backrest surface 11 of the right end seat 1A is shown.
Is inclined rightward with respect to the front by + α, and the backrest surface 11 of the left end seat 1C is inclined leftward with respect to the front by −α, so that the occupant sits slightly outward. Will be. The inclination angle α of the backrest surface 11 can be easily obtained by forming the cushioning material such that the thickness of the cushioning material is thicker on the inside and thinner on the outside when the cushioning material incorporated in the seat back 4 is formed. be able to. The inclination angle α is about 5 ° to 30 °, and is determined by the seat pitch. On the other hand, the backrest surface 11 of the central seat 1B correctly faces the front as in the case of the above-described conventional seat, so that the inclination angle in the left-right direction is 0, and the occupant sits facing the front. Reference numeral 13 denotes a foldable rear seating table attached to the back side of the seat back 4.

In such a three-seater seat 20, the backrest surfaces 11 of the seats 1A and 1C located at both ends are provided.
Are tilted by + α and −α, respectively, so as to face the outside, so that the body of the person sitting on these seats 1A and 1C can be naturally turned outward. on the other hand,
Since the person sitting on the central seat 1B faces the front, the adjacent shoulders of the seated persons are shifted back and forth even if the seat pitch is the same as before. Therefore, the shoulders and elbows of the occupants do not touch each other, and the faces of the occupants do not come close to the next occupant.

FIG. 4 is a plan view showing an example in which the present invention is applied to a seat for two persons. This embodiment is as shown in the figure.
Two seats 1A and 1B, which are parallel to each other and face forward, are arranged side by side to form a two-seat seat 30. The backrest surface 11 of each of the seats 1A and 1B is inclined by an angle α with respect to a plane parallel to the direction in which the seats 1A and 1B are arranged so as to face the outside of the two-seat seat 30, respectively.

In the two-seat seat 30 having such a structure, the backrest surface 11 of each of the seats 1A and 1B is also provided.
Is tilted so as to face outward, so that the body of the occupant can be naturally directed outward. Therefore, even if the seat pitch is the same as the conventional one, the shoulders and elbows of the adjacent seated people do not touch, and the seats of the adjacent seated people do not enter the field of view because they sit slightly away from each other. .

FIG. 5 is a plan view showing an example in which the present invention is applied to a seat for four. In the present embodiment, the back surface 11
A seat 1A inclined outward by an angle α with respect to a plane parallel to the direction in which the seats are arranged, and a normal seat 1B having a backrest surface 11 facing the front. The four seats 41 are configured by arranging the seats in parallel. The four sheets are alternated as shown in the figure.
Parallel and facing forward. When the two-seat seats 40 are arranged side by side, the seat 1A in which the backrest surface 11 is inclined outward by angles + α and −α is the outside, in other words, the normal seat 1B in which the backrest surface 11 faces the front.
Are arranged side by side so as to be adjacent to each other. The distance D between the two two-seat seats 40 is twice as large as the normal distance since the two armrests 3 are adjacent to each other.

In the four-seat seat 41 having such a structure, the left end and the right end of the seat 41 face left and right by + α and −α with respect to the front, respectively, and the inside person faces the front. As in the above-described embodiment, the shoulders and elbows do not touch each other, and the face of the next occupant does not enter the field of view. In this case, with respect to the two inner seats 1B, the backrest surfaces 11 are both facing the front, but the seat interval D is set to be twice as large as that of the normal by the two armrests 3, so it is not so bothersome. There is no touching of shoulders and elbows.

FIG. 6 is a plan view showing an example in which the present invention is applied to a double seat type seat for five persons. In this embodiment, a five-seat seat 50 is configured by arranging the three-seat seat 20 shown in FIGS. 1 to 3 and the two-seat seat 30 shown in FIG. 4 side by side. is there. In this case, the distance D between the three-seat sheet 20 and the two-seat sheet 30 is twice as large as the normal distance because the two armrests 3 are adjacent to each other.

In the five-seat seat 50 having such a structure, the two occupants seated on the two-seat seat 30 are shown in FIG.
Shoulders and elbows do not touch each other as when sitting on
Also, the face of the next occupant does not enter the field of view. FIGS. 1 to 3 also show three occupants sitting on the three-seat seat 20.
The shoulders and elbows do not touch each other as in the case of sitting on the three-seater seat 20 shown in FIG. In this case, since the backrest surface 11 of the second seat 1A from the left is inclined rightward and the backrest surface 11 of the third seat 1C is oriented leftward in FIG. The two seated occupants sit obliquely and face each other, but their seat spacing is set to twice the normal size by the two armrests 3 so that they do not care much about their shoulders and elbows. There is no touch.

Although the present invention is applied to a two-seat, three-seater, four-seater and five-seater double-seat type seat, the present invention is not limited thereto. No, two-seat sheets 30, 40 and three-seat sheets 2
By appropriately combining 0, the present invention can be applied to a double seat type seat for six persons or more. Alternatively, two two-seat sheets 30 may be arranged in parallel to form a four-seat sheet.

[0016]

As described above, in the double seat type seat according to the present invention, the backrest surface of each seat in the two-seat seat is inclined outward with respect to a plane parallel to the direction in which the seats are arranged. Therefore, when the seated person is seated, the body can be naturally turned outward. Therefore, without increasing the seat pitch, the shoulders and elbows of the occupants do not touch,
In addition, the face of the next seated person does not enter the field of view, so that the sitting comfort is comfortable and the seated person can endure sitting for a long time.

Further, according to the present invention, in the three-seat seat, the backrest surfaces of the seats at both ends are inclined outwardly with respect to a plane parallel to the direction in which the seats are arranged, so that a person sitting on the seats at both ends can be seated. The body can naturally turn outward. Therefore, without having to increase the seat pitch, without touching the adjacent seat occupant between the shoulder and elbow, also without entering the seated person's face is the field of view of the next door, withstand a long time of sitting comfort is a comfortable obtain.

Further, according to the present invention, in the four-seat seat, the backrest surfaces of the seats at both ends are inclined outward with respect to a plane parallel to the direction in which the seats are arranged. The body can be naturally directed outward. Therefore, without increasing the seat pitch, the shoulders and elbows of adjacent occupants do not touch each other, and the faces of the adjacent occupants do not enter the field of view, making it comfortable to sit and withstand long hours of sitting. obtain.

Further, in the double seat type seat according to the present invention, it is only necessary to incline only the backrest surface, and other parts can be used as they are, so that the cost is very high.
