Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cross seat with a spare seat applied to a railway vehicle. The present invention relates to a cross seat with a spare seat capable of sufficiently increasing the seat capacity of the seat.

[0002]

2. Description of the Related Art Considering a case where a spare seat conventionally found in buses and the like is applied to a railroad car, when it is folded next to a cross seat, the floor area projected by the folded thickness stands up. There is a rule that rail cars do not include the area for passengers. That is, if the spare seats found in buses and the like are directly applied to railway vehicles, it will not be possible to secure an increase in the number of seats and the number of seats will decrease.

In most conventional spare seats for buses and railroads, armrests are installed on the aisle side, and people often come and go through the aisle, especially in railway cars.
It is desirable to equip the spare seat with an armrest so that the seated person and the passerby do not disturb each other. Further, the backrest of the spare seat, which is usually installed on the passage side of the cross seat, has a low height.

[0004]

Therefore, in the conventional spare seat, there is a problem that the seating capacity cannot be increased and the seating capacity cannot be sufficiently increased in the off-peak time. Also, with conventional spare seats, the height of the backrest is low, so many of them cannot support their heads when accelerating or decelerating the vehicle, which is very uncomfortable for a sleeping person. There is also a problem that even in a normal seated state, the person is supported by the neck and becomes very tired.

The present invention has been made in view of the above circumstances, and it is possible to secure a sufficient increase in the number of seats for a standing seat, a sufficient increase in the number of seats for a seat during a quiet time, and to prevent a seated person from getting tired. An object of the present invention is to provide a cross seat with a spare seat that can be made comfortable.

[0006]

In order to achieve the above object, according to the present invention, a cushion portion and a backrest portion are folded and stored in a frame of a cross seat on the main body side when not in use, In use, a spare that is provided to move the cross sheet on the main body side to the aisle side by a mechanism such as a slide system or a link system and put it out on the aisle side, and then set the cushion and backrest part to the used state. It is characterized in that it is provided with a seat, and when the spare seat is used, it becomes a seat for two persons.

[0007]

With the above structure, when the spare seat is not used, the normal cross seat is used alone, and the spare seat is stored so as not to disturb the standing passengers. Can be achieved. Further, when the spare seat is used, it becomes a seat for two persons, so that it is possible to sufficiently increase the number of seats in a quiet time. Further, not only the cross seat on the main body side but also the spare seat can have a high height of the backrest, so that a spare seat occupant as in the conventional case is not tired.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 are a front view and a side view of a first embodiment according to the present invention. In FIG. 1, the cross sheet 1 on the main body side is in a state of being moved to the aisle side by a slide system,
The slide mechanism is composed of a slide 2 including a lock device (not shown) that slides on a total of four slide rails, a total of two air cylinders 3, and the like. The cross seat 1 includes an armrest 4.

When the spare sheet 5 is not used, the cushion portion 6 and the backrest portion 7 are stored in the frame 8 on the main body side, and in the state of FIG. 1, the cushion sheet portion 6 is folded and stored.
The backrest portion 7 is in a state of being set in use by the link mechanism 9 (see FIG. 5).

3 and 4 are a front view and a side view of a second embodiment according to the present invention. In FIG. 3, the cross sheet 11 on the main body side is in a state of being moved to the passage side by a link method, and the link mechanism is composed of a total of four operation links 12 and an air cylinder 13 and the like. And cross sheet 1
1 includes an armrest 14. When the spare sheet 15 is not used, the cushion portion 16 and the backrest portion 17 are stored in the frame (box) 18 on the main body side, and in the state of FIG. 3, the cushion sheet portion 16 and the backrest portion are folded and stored. 1
7 is pulled out from the frame (box) 18 and is set in a used state.

FIG. 5 is a spare sheet 5 in the first embodiment.
FIG. 4 is a side view of the cushion cushion section 6 and the backrest section 7, showing an operation change between a stored state (shown by a chain double-dashed line) and a use state (shown by a solid line).

6 and 7 are a front view and a side view showing a modification of the first embodiment. Therefore, the same components as those of the first embodiment shown in FIGS. 1 and 2 are designated by the same reference numerals, and the duplicated description will be omitted. In this embodiment, the cross seat 1 that emerges on the aisle side has leg portions 21, and two casters 22 are attached to the leg portions 21. That is, as compared with the first embodiment shown in FIGS. 1 and 2, the legs 21 are provided, so that the strength is excellent, and the casters 22 are provided, so that the cross sheet 1 can be taken in and out very smoothly. You can do it.

In the above embodiment, the spare seat does not occupy a space when it is stored and does not become an obstacle, so that the number of standing passengers can be increased. Further, when the spare seat is used, it becomes a seat for two persons, so that it is possible to sufficiently increase the number of seats in a quiet time. Further, even in the spare seat, since the height of the backrest can be set high, it is possible to reliably prevent the seated person from getting tired. Further, since the cross seat on the main body side has an armrest, it is possible to prevent the seated person and the passerby in the passage from bothering each other. Further, the sheet according to the present invention can be conveniently used as a combined sheet with an attendant for dealing with people with disabilities. The cross seat moving mechanism on the main body side is not limited to pneumatic pressure, and various types such as hydraulic pressure, electric power, or manual operation can be selected.

[0014]

As described above, according to the present invention, when the spare seat is not used, the normal cross seat is used alone and the spare seat is stored so as not to disturb the standing passengers. It is possible to increase the number of seats and passengers. Further, when the spare seat is used, it becomes a seat for two persons, so that it is possible to sufficiently increase the number of seats in a quiet time. Further, not only the cross seat on the main body side but also the spare seat can have a high height of the backrest, so that it is possible to surely prevent the conventional seat occupant from getting tired.
