Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a seat structure in a vehicle.

[0002]

[Prior Art]

 Conventionally, for example, one form of a route bus operating in the city is shown in FIG.

That is, such a bus a has a large number of seats c for two persons arranged on the left and right sides of the floor b in the front-rear direction with a certain space in the front-rear direction. A passage d is formed between c 1 and c 2.

[0004]

[Problems to be solved by the device]

 However, since the seat c is for two passengers in the bus a as described above, when the passenger seated on the window side passes through the front of the passenger seated on the aisle d side to the aisle d side, Since the feet of the seated passenger and the seat c immediately in front of the passenger are close to each other, there is a problem that it is difficult to pass through the space between them to the side of the passage d.

Further, in such a bus a, since the left-right width e of the vehicle is limited, the left-right width g of the passage d is determined by the left-right width f of each of the left and right seats c, c. If the right and left width f of the passenger car is increased, the passengers can sit comfortably, while the left and right width g of the passage d becomes narrower, and other passengers stand up in the same passage d when getting on and off through the passage d. There is a problem that getting on and off is difficult.

On the bus a for city routes, it is often the case that the right and left width g of the passage d is formed as wide as possible because a large number of passengers must be operated during rush hour. Although the passengers can be transported while standing up and the transportation efficiency is good, the seating space becomes smaller because the lateral width f of the seat c needs to be reduced correspondingly, and the passenger seated in the seat c feels cramped. There was a problem of giving.

[0007]

[Means for Solving the Problems]

 Therefore, in the present invention, a plurality of single-seat seats with a backrest standing upright at the rear of the seat are arranged adjacent to each other in the left-right width direction, and are displaced from each other by a certain width in the front-rear direction. It is intended to provide a seat structure in a vehicle, which is characterized in that

Further, in the present invention, a plurality of seats for one person are integrally formed, and the upper surface of the seat portion and the front surface of the backrest portion are each formed by curving in a concave shape.

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a partial plan view of a city route bus A having a seat structure according to the present invention.

In this city route bus A, seats B for two passengers are arranged on the left and right sides of the floor 1 at regular intervals in the front-rear direction, and a passage 1a communicating in the front-rear direction is formed in the center. Is formed. W1 is the left and right width inside the vehicle, W2 is the left and right seat width, and W3 is the passage width W3.

As shown in FIGS. 1 to 4, the seat B is configured as a pair of two-seat seats for inside and outside (left and right sides), and the seat support machine is erected on the floor 1. Inner and outer seats 3 and 4 are mounted on the frame 2, inner and outer backrests 5 and 6 are respectively erected at the rear of the seats 3 and 4, and the end of the inner seat 3 on the side of the passage 1a. The armrest part 7 is attached to the structure. Here, the inside means the side located on the passage 1a side, and the outside means the side located on the window side.

Moreover, the inner and outer seat portions 3 and 4 are displaced rearward by a predetermined width W4 (for example, 5 to 10 cm) from the inner seat portion 3 located on the side of the passage 1a than the outer seat 4 located on the window side. I am doing it.

Further, the upper surfaces of the seat portions 3 and 4 and the front surfaces of the backrest portions 5 and 6 are concavely curved to form a so-called bucket seat shape.

Further, in this embodiment, the inner seat portion 3 and the inner backrest portion 5, and the outer seat portion 4 and the outer backrest portion 6 are integrally formed, but they may be formed separately.

Although it is intended for two-seater, three or more seats can be used if necessary, and at this time, the seat and the backrest for at least one seat are positioned at a certain width W4 in the front-rear direction. You can leave it off.

The embodiment of the present invention is configured as described above, and according to this embodiment, the following operational effects are produced.

That is, when the city route bus A is operated, the passengers should be seated on the left and right sides of the floor 1 at seats B arranged at regular intervals in the front-rear direction. Two seats can be seated in each seat B, one inside the passage 1a and one outside the window.

At this time, the inner seat portion 3 and the inner backrest portion 5 are seated on the inner seat portion 3 because the inner seat portion 3 and the inner backrest portion 5 are displaced rearward by a predetermined width W4 from the outer seat portion 4 and the outer backrest portion 6. The front and rear widths of the passenger's feet are wide.

Therefore, when the passenger seated on the outer seat 4 on the window side exits the passage 1a by passing in front of the passenger seated on the inner seat 3 in order to get off, etc., the inner seat 3 In order to make it easier for passengers seated on the floor by increasing the front and rear width of the space around their feet, they do not have to change their postures or take up the trouble of standing up and moving to the aisle 1a. Can easily get out of the aisle 1a and get off smoothly, but when other passengers are seated in the vacant outer seat part 4 as well, in front of the passenger seated in the inner seat part 3 as well. It is possible to smoothly seat on the outer seat portion 4 through

Moreover, since each seat B is in the shape of a bucket seat, it is possible to secure a good seating center for the seat B and to make the seat lateral width W2 of the seat B as small as possible. Therefore, the passage width W3 can be increased accordingly.

Therefore, the passengers can smoothly get on and off through the aisle 1a, and the wide aisle 1a can be utilized as a passenger's boarding space, so that the transportation efficiency is particularly high during rush hour. Can be improved.

Since the inner seat portion 3 and the inner back portion 5 and the outer seat portion 4 and the outer back portion 6 of each seat B are respectively in the shape of a bucket seat, shoulders of passengers seated next to each other, etc. Since passengers can be prevented from touching each other, each passenger can enjoy the bus movement comfortably.

5 and 6 show a seat B as a second embodiment, in which the rear tilt angle θ1 of the inner back portion 5 is, for example, 20 degrees, and the rear back portion 6 is rearward. The backward tilt angle θ1 is set to be larger than the backward tilt angle θ2, for example, with the tilt angle θ2 set to 15 degrees. θ3 is an inclination angle of the headrest portion 5a of the inner backrest portion 5, for example, 5 °, and θ4 is an inclination angle of the headrest portion 6a of the outer backrest portion 6, for example, 8 °.

In this way, when a passenger is seated on the inner seat portion 3 and another passenger is seated on the outer left seat portion 4, the passenger seated on the inner seat 3 is By leaning against the backrest 5, the space immediately in front of the passenger can be widely opened, so that other passengers can easily pass through the space and the seating can be performed smoothly. I have to.

FIG. 7 shows a seat B as a third embodiment, in which the cushion of the inner seat portion 3 is formed softer than the cushion of the outer seat portion 5.

In this way, for example, when passengers of the same weight are seated on the inner seat portion 3 and the outer seat portion 5, the surface portion of the inner seat portion 3 is larger (for example, 15 mm to 20mm) It is possible to open the space immediately in front of the passenger seated on the seat 3 by compaction, and other passengers can easily pass through the space, allowing for smooth seating. I am able to do it. H1 is the height of the central portion of the seat after the settlement of the inner seat portion 3, and H2 is the height of the central portion of the seat portion after the settlement of the outer seat portion 4.

[Effect of the device]

 According to the present invention, the following effects can be obtained.

For example, when arranging seats in the city route bus, if two seats for one person are arranged adjacent to each other on the left and right sides of the floor, and a passage is formed in the center of the floor. Of the two adjacent seats, the seat on the aisle side is shifted rearward by a certain width from the seat on the window side so that passengers seated on the seat on the window side are seated on the aisle side. Passengers seated in can be allowed to easily enter the aisle.

Therefore, the passengers on the aisle side do not need to change the seating posture so that the passengers on the window side can easily enter the aisle, and do not have to perform the complicated actions that have been conventionally performed such that they stand up and move to the aisle. ..

By integrally forming the plurality of seats arranged as described above, the work of arranging the seats can be simplified.

The upper surface of the seat portion and the front surface of the backrest portion of each seat are respectively curved in a concave shape to form a so-called bucket seat shape, so that a comfortable sitting comfort can be ensured. Since the left and right width of the seat can be made as small as possible, for example, in the case of city buses, the aisle width can be widened accordingly, and passengers can get on and off smoothly through the aisle. In addition, since this wide passage can be used as a passenger space for passengers, it is possible to improve transport efficiency especially during rush hour.

By forming the seat in a so-called bucket seat shape as described above, it is possible to prevent the shoulders and the like of passengers sitting next to each other from touching each other. The feeling of tightness and discomfort is eliminated, and comfortable vehicle movement is possible.

Since the back tilt angle of the backrest portion of the seat displaced rearward is made larger than the back tilt angle of the backrest portion of the seat displaced frontward, The passenger sitting on the seat of the seat on the side of the seat leans on the backrest of the passenger, and thus the space immediately in front of the passenger can be widely opened, allowing other passengers to pass through the same space. You can make it easier.

Since the cushion of the seat portion of the seat displaced to the rear side is formed softer than the cushion of the seat portion displaced to the front side, the seat displaced to the rear side The seat part of the seat of the seat collapses greatly, and the space in front of the passenger seated in the seat can be widely opened, which facilitates the separation and sitting of other passengers passing through the space. be able to.
