2. Description of the Related Art Conventionally, as a floor structure of a vehicle such as an automobile, it is generally well known that a floor panel is provided with a step having a lower front side at an intermediate portion in a vehicle body front-rear direction. For example, so-called RV for outdoor leisure
For (recreation vehicle) type vehicles and 1-box type vehicles that carry many passengers or luggage,
A rear floor, the height of which is determined by the upper end position of the rear tire house, is provided with a floor structure in which a floor portion in front of the rear tire house is lowered, and the first row is placed on the lowered front floor. It is known that a seat (front seat) and a second-row seat (intermediate seat) are sequentially arranged, and a third-row seat (rear seat) is arranged on the rear floor.

In a vehicle of this type, in order to store and load a larger amount of luggage, the rear seat is removed or folded, and the intermediate seat is slid toward the front of the vehicle body and then folded and stowed. It may be required to make the entire rear space of the seat available as a luggage space. Incidentally, as a seat that can be removed from the floor in such a case, for example, Japanese Utility Model Laid-Open No. Sho 63-91947 discloses a removable seat for a vehicle that is a slide type and can be removed.

[0004]

By the way, as described above, when the entire rear space of the front seat is used as the luggage space, the intermediate seat is slid to an appropriate front and rear position and then folded up. The intermediate seat is stored so that it leans against the back of the front seat, but the front and rear positions of the front seat differ depending on the physique of the seated occupant each time, so the position where the intermediate seat is folded (that is, the slide position) is also the front seat. It is necessary to adjust each time according to the front and rear position of. However, since the conventional slide type seat has a structure that cannot be slid after being folded once, if the folded and stored front and rear positions are not appropriate for the front seat, the seat is returned to the used state again. It is necessary to slide it up and readjust its front-rear position, and there is a problem that setting and adjusting the front-rear position for folding and storing is cumbersome and inconvenient.

Further, as described above, even if a large luggage compartment space is secured behind the front seat, if there is a step on the floor, it is not convenient as a luggage storage space and a sufficiently effective space can be used. There will be some disadvantage in trying to achieve. Therefore, after the intermediate seat is folded and stored, a floor board (flat plate) is disposed above the lowered front floor so as to be substantially flush with the rear floor surface, and a flat flat surface substantially continuous with the rear floor is provided. It is possible to form a floor surface. However, how to support the floor board above the front floor, or how to store the floor board during normal times when the floor board is not located on the front floor, etc. There was a problem that it was very difficult to deal with within.

The present invention has been made in view of the above problems, and it is easy to adjust the folding storage position, and it is relatively easy to support the floor board used when expanding the luggage space and store it in the normal state. An object of the present invention is to provide a vehicle seat structure that can be performed.
