DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle seat structure in which a storage container is provided in a lower space portion of a cushion body.

[0002]

2. Description of the Related Art In vehicles such as automobiles, since the indoor space is limited, storage of luggage is naturally limited. Therefore, for example, there is an automobile that uses a space under a seat.

FIG. 15 shows a seat structure in which a storage portion is provided by utilizing a space under the seat. In this seat structure, rails 101 facing each other in the front-rear direction are provided in a space under the seat cushion 100. Is provided with an under tray 102 that can slide along. According to this conventional technique, not only can the undertray 102 not be easily removed, but also cannot be removed from the rear seat.

Therefore, a prior art (Japanese Utility Model Laid-Open No. 2-61746) is known in which the cushion body of the seat on the passenger seat side of the automobile is rotated so as to rise forward to utilize the lower space of the cushion body. Have been. In this prior art, as shown in FIG.
3 has a front end rotatably mounted on a frame 104 and a box-like body 105 disposed inside the frame 104.

[0005] In this prior art, the inside of the box-shaped body 105 is used for storage, and the cushion body 103 is raised forward to open the upper surface of the box-shaped body 105.

[0006]

However, according to the above-mentioned prior art, it is difficult to take out the box-shaped body 105, and the box-shaped body 105 cannot be carried in place of a basket.
Further, there is a possibility that the box-shaped body 105 may rattle in the frame 104. Further, it was difficult to put the hand in the gap of the cushion body 103 to raise the cushion body 103.
Further, instead of the box-like body 105, as shown in FIG.
If the storage container 106 is increased in capacity and the heavy object 107 is put therein, the hanging portion 108 of the storage container 106 may bend and the storage container 106 may be damaged.

An object of the present invention is to solve the above-mentioned problems and to provide a vehicle seat structure capable of improving the rigidity of a flange portion of a storage container.

[0008]

According to the present invention, there is provided a seat cushion comprising a cushion frame and a cushion body, and a seat back attached to a rear end of the seat cushion. Wherein the cushion body is mounted on the cushion frame so as to be rotatable forward about the front end portion, and a storage container is detachably attached to a lower space portion of the cushion body. At least at the upper ends of both sides of the container, a flange portion is provided which is engaged with the upper end pipe portion on both sides of the cushion frame. That is, a plurality of portions are formed at predetermined intervals along the longitudinal direction of the portion.

[0009]

When the storage container is used, when the band of the cushion body is pulled, the latch body is pulled and the engagement with the striker is released. Then pull the band further to raise the cushion body. Thus, the cushion body is pivoted about the hinge and is raised forward. When the cushion main body is raised, the upper surface of the storage container is opened, so that shopping or other luggage can be stored in the storage container. The storage container can be removed from the fastening portion and pulled up, so that the storage container can be removed from the upper end frame portion of the side frame and carried around. The storage container is provided with a flange portion at least at the upper end of both side portions, which is engaged with the upper end pipe portion at both side portions of the cushion frame. A plurality at predetermined intervals along the longitudinal direction of the part,
Since it is formed, the rigidity of the flange portion of the storage container can be improved.
