Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a long seat for a vehicle, which is installed horizontally along the inner wall of a vehicle such as a commuter train or a bus so that a plurality of people can sit side by side.

[0002]

2. Description of the Related Art A vehicle long seat of this kind is provided, for example, as disclosed in Japanese Utility Model Publication No. 57-51136, with a plurality of brackets fixed to the inner wall of the vehicle body by bolts and the like, and horizontally mounted on these brackets. A seat cushion is provided on a seat frame having a required length, which is formed of a penetrating member or a shell fixed in this way.
In such a long vehicle long seat, even if the inside of the vehicle is crowded with passengers, only a small number of seats can be seated. This is due to the poor manners of the occupants, but the main reason is that the division of each seat unit is not clear.

Therefore, for example, in a long seat with a capacity of 7 people, the first passenger often sits on both ends, the next passenger sits in the middle, and the latter passenger sits in the middle, so that the seat of the person sitting in the middle. The position (position) is made different from that of the skin (cloth) of the other seats to make it clear, and it is devised to surely seat seven people. Alternatively, pattern seating or quilting is applied to the center of each seat portion of the skin of the long seat so that the seated position can be known to the seated person.

Further, by cutting and sewing the outer skin of a cushion seat of a long seat for each individual seat, the joints of the outer skin allow the seated person to know the width of each seat, or Suspending the joints of the outer skin with a pulling cloth etc. to the inside of the pad and making it concave in a groove shape so that the seated person can know the width of each seat,
We are devised so that the seating capacity is as large as possible.

[0005]

However, in the above-mentioned conventional long seats for vehicles, a part of the outer skin is colored differently, a pattern weave or quilting is applied, and a seam or a seam is attached to the outer skin for each seat. Even if grooves are provided, they can be visually recognized before the passenger sits, but they cannot be seen after sitting down, and they can hardly be felt by the body such as the buttocks and back. . That is,
Since the entire seat cushion is a bench seat type that is substantially flat in the longitudinal direction, even if the seated person sits in a halfway position, the sitting comfort does not change and the passengers do not feel discomfort, so the passengers inadvertently shift from the seat position. I often sit down, and many people don't notice it. Due to these reasons, the fact is that even today, it is rare for people to sit down to the full capacity.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to allow a seated person to clearly recognize the position (compartment) of each seat unit, visually or with a feeling of sitting. If the seated person shifts halfway to the position of the seat unit, the waist will be slanted and the seat will be uncomfortable and you will naturally sit back in the correct position, and by sitting in that correct position you will be very comfortable to sit. It is desirable to provide a long seat for a vehicle, which inevitably ensures that the number of seated persons can sit down, is easy to manufacture, can reduce the cost, and has an excellent design.

[0007]

In order to achieve the above-mentioned object, a vehicle long seat of the present invention is provided with a seat frame of a required length which is attached and fixed to an inner wall of a vehicle body of a vehicle such as a commuter train or a bus. By integrally molding the skin and the pad, the seat cushions are arranged in a row in a three-dimensional shape with concavities and convexities that hold a seated person for each seat.

[0008]

In the long vehicle seat having the above-mentioned structure, the seat cushions arranged on the seat frame have a three-dimensional shape with projections and depressions for holding seated persons in each seat. The position (section) of each seat unit of the seat cushion becomes visually clear to the passenger before sitting. Further, even when the passenger is seated, the three-dimensional shape of the seat unit with unevenness can be recognized by the feel of the body such as the hips, and the position (section) of each seat unit can be clearly recognized for each person. Ignoring this, if the seated person shifts halfway to the position of the seat unit, the convex part on one side makes the waist slanted, which makes it uncomfortable to sit and naturally sit in the correct position in the center of each seat unit. It will be fixed. When sitting in that correct position, the center is concave and both sides are convex, so that the body of the seated person is held appropriately from the left and right, and the sitting comfort becomes very good. This inevitably ensures that the seating capacity will be seated.

Further, since the seat cushion is manufactured by integrally molding the skin and the pad, as described above, the seat cushion can be easily and surely manufactured in a three-dimensional shape with unevenness that holds each seated person. The cost can be reduced, and the three-dimensional shape has no wrinkles or slack in the skin, and is excellent in design.

Can be firmly attached to a proper height without legs.

A seat cushion 11 is installed on the surface of the shell 5 of the seat frame 1. The seat cushion 11 is manufactured by integrally molding a skin 12, a pad 13 (see FIG. 3), and a backing plate 14. That is, although not shown, a mold equipped with a heating device and a vacuuming device is used, a skin material is set in the mold to evacuate, and a pad material (foaming material) such as urethane foam from above is used. Is injected, the backing plate 14 such as a hard board is placed on the backing plate, and the pad material is foamed to integrally form the outer skin 12, the pad 13, and the backing plate 14. The seat cushion 11 is manufactured by the above-described integral molding independently for each seat unit. The seat cushions 11 that are independent for each seat unit are in a state of having a three-dimensional shape with projections and depressions so as to hold one seated person, as shown in FIG. That is, in each seat cushion 11, the central portion 11a of the upper surface is rounded so as to wrap around the hips of the seated person, and the left and right side portions 11b are smoothly raised to hold the hips from the left and right, and the bank extending in the front-rear direction. It has a convex shape like this. The front end portion 11c has a corrugated shape in which the left and right thighs of the seated person hit a little, and is rounded downward and folded back, and the front side penetration member is provided on the back surface thereof. It has a U-shaped portion 11d into which 3 is fitted. Further, like the shell 5, the rear portion 11e is erected in an arc shape to a considerably high position.

A total of seven independent seat cushions 11 (half omitted in the drawing) for each seat unit shell 5
They are installed side by side on the top. As these fixing means, a plurality of either female or male hooks (also called snaps) 15a are provided at the upper edge of the rear portion 11e of each seat cushion 11 and the edge of the U-shaped portion 11d at the lower front end. A plurality of hooks 15b opposite to each other, which are fitted and engaged with each other, are provided on the rising upper end portion of the shell 5 and the lower surface portion of the front penetrating member 3 respectively, and the opposing ones are mutually opposed. A plurality of female or male surface fasteners 16a are attached to the lower surface of the backing plate 14 of each seat cushion 11 by gluing or the like, and are engaged with them. Are attached to the upper surface of the shell 5 so that their opposing members are connected to each other. Thus, the seat cushions 11 are attached so that they do not move unintentionally.

The integral molding of the seat cushion 11 is performed by vacuum molding, heat press molding, slush molding, high frequency molding or the like to form the outer skin 12 into a desired shape in advance, and the outer skin 12 is mounted in a foam mold. It is also possible to use a method in which a pad material (foam material) such as urethane home is injected and foamed in the molded skin.

A seat back cushion 21 manufactured separately from the seat cushion 11 is a seat frame 1.
It is attached to the front of the rear rising part. This seat back cushion 21 is also the seat cushion 1 described above.
As in the case of 1, the outer skin 22, the pad 23, and the backing plate 24 are integrally molded separately for each seat unit, and are manufactured in a three-dimensional shape.

Each of these seat back cushions 21 is
The upper and lower end portions 21a and 21b are rounded back to the back side. In addition, a pair of upper and lower hook springs (leaf springs) 25a and 25a are provided at the left and right portions of the rear surface of the backing plate 24, respectively.
b is attached. The pair of upper and lower hook springs 25a and 25b are elastically pushed into the hooking portion 4a of the rear upper through-hole member 4 of the seat frame 1 and are hooked in a state in which the seat back cushion 21 is clamped from above and below. The upper end portion 21a is joined to the vehicle body inner wall T below the window frame S, and the lower end portion 21b is joined to the upper end bent edge portion 5a of the shell 5 and the upper end edge portion of the seat cushion 11 so as to cover them from the front side. To be

However, in the case of the vehicle long seat having such a structure, the seat cushions 11 arranged in a row on the seat frame 1 are different from the conventional bench seat type.
So to speak, like the bucket seat type, each seat is individually molded individually and has a three-dimensional shape with unevenness that holds the seated person one by one, so that the position of each seat unit of the seat cushion 11 is Passengers before the (compartment) will be able to see clearly visually.

Further, even when the passenger is seated, the three-dimensional shape with unevenness of the seat unit can be recognized by the feel of the body such as the hips, so that the position (section) of each seat unit can be clearly recognized. Become. Ignoring this, if the seated person shifts halfway to the position of the seat unit, the convex part on one side makes the waist slanted, which makes it uncomfortable to sit and naturally sit in the correct position in the center of each seat unit. It will be fixed. When sitting in that correct position, the center is concave and both sides are convex, so that the body of the seated person is held appropriately from the left and right, and the sitting comfort becomes very good. This inevitably ensures that the seating capacity will be seated.

Further, since the seat cushion 11 is manufactured by integrally molding the outer skin 12, the pad 13, and the backing plate 14, as described above, the seat cushion 11 has a three-dimensional shape with irregularities for holding a seated person for each seat. Can be manufactured easily and surely in a state of exhibiting a cost, and the cost can be reduced, and even if it has a three-dimensional shape, the skin 12 does not have wrinkles or slack and is excellent in design. Furthermore, since the seat cushions 11 are individually molded for each seat, even if the outer skin 12 is torn or damaged, the individual seat cushions 11 can be replaced and repaired easily and inexpensively. Like Further, also in the seat back cushion 21, substantially the same operational effects as the seat cushion 11 described above can be obtained.

The seat back cushion 21
As described above, the seat cushion is manufactured separately from the seat cushion 11, but the seat cushion 11 may be integrally connected and molded.

In addition, in the above-mentioned embodiment, the seat cushions 11 are individually manufactured by integral molding for each seat unit, and the seat cushions 11 are arranged on the seat frame 1 by the number of seats required. It is also possible to use a seat cushion that is made by molding two or more seat units, three seat units, or more seat units in a series by integral molding, and have these seat units connected together. A combination of seat cushions is arranged on the seat frame 1 to secure a seat for the seat. Even in this case, each seat unit of the seat cushion has a three-dimensional shape with projections and depressions to hold one seated person.

[0025]

Since the vehicle long seat of the present invention is configured as described above, it is possible for the seated person to clearly recognize the position (compartment) of each seat unit visually and with a feeling of sitting. If the seated person shifts halfway to the position of the seat unit, the seat becomes uncomfortable because the waist becomes slanted and the seat naturally sits in the correct position. It is comfortable and inevitably allows a large number of people to sit on it, and it is easy to manufacture, the cost can be reduced, and the design is excellent.
