Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 to FIG. 3 are views showing a first embodiment of the present invention. This will be described with reference to FIGS. FIG.
In the middle, the direction A indicates right and the direction B indicates left. This embodiment relates to a second seat 1 of a three-row seat in a wagon vehicle. This second seat 1
Is for one person, consisting of the seat cushion 2 and the seat back 3, and is arranged side by side on the left and right.
Each second seat 1 is mounted on a storage box 5 fixed to the floor 4. The storage box 5 may be fixed to the floor 4 or may be movable back and forth with respect to the floor 4.

The storage box 5 has a shape having an opening at an upper part, and the opening is closed by the seat cushion 2. The seat cushion 2 has a front end lower surface connected to a front hinge FH provided at the opening front edge of the storage box 5, and pivots forward about the front hinge FH as shown by a two-dot chain line in FIG. Thus, the opening of the storage box 5 can be opened. A rotary hook 6 is provided at the rear of the seat cushion 2 and engages with a pin 7 formed on the side surface of the storage box 5 so that the seat cushion 2
The rear is fixed. The seat back 3 is foldable by the reclining device 15 on the seat cushion 2.

An auxiliary sheet 8 is stored in a storage box 5 below the second sheet 1 on the left side. The auxiliary seat 8 has a structure including an auxiliary seat cushion 9 and an auxiliary seat back 10. In the storage state, the auxiliary seat back 10 is
Is folded forward and turned upside down. On the lower surface of the auxiliary seat cushion 9, a leg member 11 is provided in a folded state. The auxiliary seat cushion 9 is connected to a side hinge SH provided on the left edge of the opening of the storage box 5.

Therefore, after the seat back 3 of the second seat 1 is folded on the seat cushion 2, the second seat 1 is turned forward around the front hinge FH so that the upper opening of the storage box 5 is opened. After doing
Auxiliary seat cushion 9 inside storage box 5
Is rotated around the side hinge SH,
The entire auxiliary seat back 10 can be pulled out of the storage box 5. After the auxiliary seat 8 is pulled out of the storage box 5, the leg member 11 on the lower surface of the auxiliary seat cushion 9 is rotated to be in a vertical state, and the locking means L is attached to a striker (not shown) fixed to the floor 4 in advance. When the lock is made, the auxiliary seat cushion 9 is held horizontally, and the occupant can sit down by raising the auxiliary seat back 10.

After supporting the auxiliary seat 8, the seat cushion 2 of the second seat 1 is returned to the original position so as to close the upper opening of the storage box 5, and the folded seat back 3 is erected and held by the reclining device 15. In this case, the occupant can be seated.

Next, when the auxiliary seat 8 is stored in the storage box 5, the seat back 3 of the second seat 1 is used.
On the seat cushion 2, the reclining device 15 is controlled to rotate frontward to be folded, and then the whole folded second seat 1 is rotated forward about the front hinge FH to open the upper opening of the storage box 5. After opening, after folding the auxiliary seat back 10 to the front side,
The leg member 11 is folded upward, and the entire auxiliary sheet 8 is stored around the side hinge SH.
I just need to put it back

According to this embodiment, when the auxiliary sheet 8 is not used, the folded auxiliary sheet 8 is stored in the storage box 5.
Since the auxiliary sheet 8 is completely stored in the second sheet 1, the auxiliary sheet 8 does not exist at all on the side of the second sheet 1.
Side space S can be secured widely, and the getting on / off property and the walk-through property can be improved.

Since the storage box 5 of the second seat 1 on the right side is empty, it may be used for storing an air conditioner unit, a refrigerator, a refrigerator, a small container, a simple toilet, and the like.

FIG. 4 is a diagram showing a second embodiment of the present invention. The difference between the second embodiment and the first embodiment is the position where the second seat 1 supports the seat back 3. That is, the seat back 3 is
It is independently fixed to the rear surface. In such a case, when opening the upper opening of the storage box 5, only the seat cushion 2 needs to be rotated to the front side, so that much work is not required and workability is good.

Next, FIGS. 5 to 10 are views showing a third embodiment of the present invention. The third embodiment shows the second embodiment more specifically. The figure shows only the second sheet 16 on the left side. In the storage box 17 of the second seat 16 according to this embodiment, a frame 18 called a riser is integrally fixed around the storage box 17. The left and right sides of the frame 18 are the floor 4
, Via a slide rail 19 (see FIG. 10).
The storage box 17 is slidably supported back and forth. Since the rigidity of the storage box 17 is maintained by the frame 18, by supporting the slide rail 19 on the frame 18, the storage box 17 is not deformed even if the storage box 17 is slid back and forth.

Then, the seat cushion 20 of the second seat 16 can be turned forward around the pair of left and right front hinges FH provided at the front end of the frame 18 to open the opening of the storage box 17. Frame 1
A lower end of the seat back 21 is supported at the rear end of the seat 8 such that it can recline freely.

The upper edge of the left side of the frame 18 is provided with two notches 22 at the front and rear, and the auxiliary seat cushion 24 of the auxiliary seat 23 is turned through two side hinges SH attached thereto. It is movably supported.
Thus, the front hinge FH and the side hinge SH
Also, the support strength of the seat cushion 20 and the auxiliary seat cushion 24 is improved because the seat cushion 20 is attached to the frame 18.

At the rear end of the auxiliary seat cushion 24, similarly to the previous embodiment, an auxiliary seat back 25 is supported so as to be able to descend, and a lower leg of the seat cushion 24 is similarly provided with a leg member 26 which can be folded. Have been. Further, a table surface 27 is formed on the back surface of the auxiliary seat back 25 of this embodiment.
If the auxiliary seat back 25 is taken out from the storage box 17 and the auxiliary seat back 25 is kept face down, it can be used as a table. Further, since a concave portion 28 for a cup holder is also formed on the table surface 27,
You can also put drinks in cans and cups. When the auxiliary sheet 23 is used, appropriate small items can be stored in the storage box 17. Further, the storage box 17 may be made removable.

In the above description of each embodiment, the example in which the auxiliary sheets 8 and 23 are provided on the second sheets 1 and 16 has been described. However, the auxiliary sheets 8 and 23 may be provided on a third sheet or other sheets.

[0032]

According to the first aspect of the present invention, when not in use, the folded auxiliary sheet is stored in the storage box in an inverted state, so that the auxiliary sheet does not exist at all on the side of the main sheet. A wide side space of the main seat can be secured to improve the getting on / off and walk-through properties.

According to the second aspect of the present invention, when the seat back is turned forward around the front hinge with the seat back folded on the seat cushion, there is no obstacle around the storage box, and the auxiliary seat is stored. The work is easy, both when stored in a box and when removed.

According to the third aspect of the present invention, since the seat cushion is fixed to the rear portion of the storage box,
When the storage box is opened, only the seat cushion needs to be turned to the front side, and workability is good.

According to the fourth aspect of the present invention, since the slide rail is supported by the frame, the rigidity of the storage box is maintained by the frame, and the storage box is not deformed even when the storage box is slid. Further, since the front hinge and the side hinge are also attached to the frame, the supporting strength of the seat cushion and the auxiliary seat cushion is improved.
