[Effect of device]

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

(1) In the present invention, one end of the seat is attached to the inner wall of the vehicle body, while the upper end of the backrest provided at the rear end of the seat is attached to the ceiling wall of the vehicle through the support member. Since the seat is installed by mounting it, the seat can be reliably supported between the inner wall and the ceiling wall, and a seat column must be provided between the seat and the floor of the vehicle body. Therefore, it is possible to form a wide foot insertion space and to secure a large degree of freedom of the inserted foot.

Therefore, the occupant seated in the seat immediately after can extend his / her foot into the foot insertion space formed below the seat portion of the seat immediately before, and in this case, the empty space for foot insertion. Due to the large degree of freedom of the legs within the space, the seated person can take a comfortable sitting posture.

(2) Since there is no seat pillar, when a seated person sits on or leaves the seat pillar, no troubles such as catching a foot on the seat pillar occur, and cleaning of the floor surface is performed reliably and easily. be able to.

(3) Since it does not have a seat column, it can also be used as a luggage storage area.

(4) The support member can also function as a grip portion.

(5) Since the seat is supported by the inner wall and the ceiling wall of the vehicle body in a both-supported state, the rigidity of the inner wall can be reduced and the seat portion can be attached to the inner wall. The members can also be simplified and reduced in weight.

(6) In the configuration of (1) above, when the seat portion and the backrest portion are integrally formed, the strength of the seat mounted in a erected state between the inner side wall and the ceiling wall is ensured satisfactorily. be able to.

(7) Even when one end of each of the seat and the backrest is attached to the inner side wall of the vehicle body and cantilevered, the foot insertion space is wide between the seat portion and the floor surface of the vehicle body. Since it can be formed and the flexibility of the inserted foot can be secured, the seated person can take a comfortable sitting posture in this case as well.

(8) In the configuration of (7) above, when the seat portion and the backrest portion are integrally formed, the strength of the seat cantilevered on the inner wall can be ensured favorably.

(9) When one side portion of the seat portion is supported by a gantry arranged on the floor surface of the vehicle body and one side end portion of the backrest portion is attached to the inner wall of the vehicle body, While the seat can be reliably supported by the upper mount, one end of the backrest can be supported by the inner wall, so that sufficient strength can be secured even for a seat for two people, for example. it can.

(10) In the configuration of (9) above, when the seat portion and the backrest portion are integrally molded, the strength of the seat can be further improved, and therefore, it is also applied to a seat for multiple people. Can be made.

(11) When the mount supporting the seat is arranged with a certain distance from the inner wall of the vehicle body, it is possible to secure a piping space such as a duct between the mount and the inner wall. In addition, it is possible to secure a wide space directly below the seat.
