BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle seat installed in a spring or a train, and more particularly to a vehicle seat having a simplified structure and excellent versatility.

[0002]

2. Description of the Related Art In a bus or a train where an unspecified number of people can ride, not only is it necessary to arrange as many seats for passengers as possible in a narrow space, but also the weight of the entire seat is sufficient. It must be as light as possible while maintaining high rigidity. Also, since this kind of vehicle seat must be installed with dozens of legs in one passenger compartment, it must have a structure that can sufficiently mass-produce, and furthermore, as in a bus, for example, And must be installed while avoiding the driver's seat. further,
This kind of vehicle seat should be able to cope with the vehicle to be installed, for example, the above-mentioned steps, the driver's seat, or the change of the inside of the vehicle, so that it must be easily The structure must be able to change the specifications.

One of the simplest seats and chairs that can meet the above-mentioned needs is a synthetic resin material such as a seat or chair installed in a park or the like as a seat body. There is a seat or a chair in which the seat body is integrally formed with a leg portion which stands on the ground or the like using bolts or the like. Such a conventional seat or chair can be freely configured from a single seat to a few seaters simply by changing the length of the legs if the seat body is placed as a single seat. Although convenient, it cannot be directly applied to a vehicle seat for the following reasons.

First, a seat in which the seat portion is formed integrally with the backrest naturally has poor cushioning properties, and swings like a vehicle in a place such as a park where there is no swing at all. It is not suitable for things that are normal. Also, in the case of a vehicle seat, for those who stand around without sitting on it, they must also be a “grab” when the vehicle shakes, but a seat or chair with a simple structure as described above Then, such processing must be renewed. In particular, when it is necessary to install in a narrow space while unifying the design, such as vehicle seats, make changes according to the installation space conditions for each seat and secure `` grasping places '' There is a considerable problem because it must be done while doing so. Further, it is naturally necessary for a seat to be applied to a vehicle in which swinging is a normal condition, and it is necessary that the seat has sufficient rigidity as a whole, and an armrest (armrest) is absolutely necessary. The above-mentioned seat or chair in which the seat portion and the backrest are integrated with each other is simply completed, so that the armrest cannot be easily attached.

Accordingly, the present inventor has constructed a seat for a vehicle by fully utilizing the advantages of a seat body integrated with a seat and a backrest (hereinafter referred to as a seat shell). The inventors of the present invention have conducted various studies on how to achieve this, and have completed the present invention.
