Description

[Detailed Description of the Invention] This invention relates to a seat device having a storage box directly below the seat plate that can be tilted forward.

Conventionally, among passenger-cargo vehicles, especially the second-row rear seats of van-type vehicles, the seat backs can be folded onto the seating surface and are pivoted to the rear floor of the vehicle via a pair of hinges. Usually, the seats were constructed so that they could be folded forward using the lower ends of the front legs as a fulcrum. In addition, the rear legs of the rear seats are generally made of bent steel pipes, and are designed to be foldable toward the bottom of the seat plate that supports the seating surface.

On the other hand, inside the vehicle, there were storage compartments for small items on both walls, but there were not many large storage compartments. These large storage compartments are placed under the seats, especially in van-type vehicles.
A small box-shaped object is installed using the space between the front and rear legs of the rear seat mentioned above and the space under the seat board, and the rear legs themselves are fixed to the rear floor as legs and side walls. It had become a storage container.

Therefore, like the back seat of a van type vehicle,
If you want to fold it to use more floor space,
Storage compartments with side walls that also serve as legs that are fixed to the floor in the rear compartment are not suitable for the rear seats of passenger/cargo vehicles such as van-type vehicles, especially for folding seat systems, because the storage compartment remains on the floor. .

The purpose of this invention was made in view of the above-mentioned conventional problems.
When the seat is combined with a relatively large storage box under the seating surface and used as a normal seating device, the space directly under the seat plate, which is an extra space, is utilized.
Moreover, the storage box itself is together with the seat cushion.
It is an object of the present invention to provide a seat device that has a storage box that can be tilted forward directly below the seat plate.

In order to achieve the above-mentioned purpose, this invention is based on a foldable seat, whose front legs are pivoted to the vehicle floor surface with a pair of hinges so that they can tilt forward freely, and the seat plate of the seat is used as a lid body, and the front legs of the foldable seat are pivoted to the vehicle floor surface using a pair of hinges. A storage box with a bottom plate having a side wall of a desired size is arranged so as to be freely tiltable forward, and the lower side wall of the storage box and the floor are removably connected by a locking device, and the upper end of the side wall and the floor surface are removably connected. It is configured to be connected to the plate by a locking device that can be freely engaged and detached.

Furthermore, the front legs of the seat are pivotally connected to the vehicle floor by a pair of hinges so that they can be tilted forward, and between the front legs, the front wall end of the storage box with a bottom plate is rotatably attached to the vehicle floor coaxially with the hinges. It is configured so that it can be pivoted.

Hereinafter, embodiments of this invention will be described in detail based on the drawings.

FIG. 1 shows a seat device 1 of this invention having a storage box 7 that can be tilted forward directly below the seat plate 3.
The backrest 2 of this seat device 1 is pivotally mounted on both sides of the rear end of the seat plate 3 by a hinge device 4 so as to be able to rise and fall freely. Further, two left and right front legs 5, which are vertically provided on the front lower surface of the seat plate 3, are pivotally connected to the floor surface F by a pair of hinges 6 so as to be rotatable back and forth.

Therefore, the seat device 1 of this invention can be folded with the backrest 2 folded down onto the seating surface as shown in FIG. 2, and then folded forward as a whole as shown in FIG. It is configured so that it can be folded.

In the folding seat device 1 as described above, the opening 8 at the upper end has a width almost equal to the width of the long back plate 3 and is located directly below the long back plate 3. A horizontally long storage box 7 is formed with an opening just below the storage box 7. At this time, the rear end surface of the seat plate is placed on the bent edge of the storage box 7.
As can be understood from FIG. 2, a storage box 7 is constructed with an opening 8 directly below the seat plate 3 of the seat device 1 of this invention, and is a bottomed box made of thin steel plate or synthetic resin. However, in the case of a thin steel plate, a band-shaped edge stopper 9 having a U-shaped cross section is attached to the above-mentioned bent edge as necessary.

As shown in the figure, the storage box 7 has a hinge (not shown) separate from the hinge 6 of the front leg 5 from both outer sides of the lower front corner, or two consecutive hinges 6' on the left and right that also serve as the hinge of the front leg 5. , 6', and is pivotally connected to the floor F so that it can be tilted forward, and on the rear lower surface of the bottom of the box, there are two left and right seats that contact the floor F when used as a seat. A short column-shaped shock absorber 14 made of rubber or the like is attached.

As shown in the exploded perspective view of Fig. 4, the continuous hinge 6'
consists of a front leg 5 located on both outer sides of the seat plate 3 and having a horizontal hole 51 at its lower end, and a shaft bored on both outer sides of the lower front corner of a storage box 7 located between the left and right front legs 5, 5. hole 71 and a hinge piece 16 that is fastened to the floor surface F.
It consists of a rotating shaft 17 that penetrates three parts of the horizontal hole 51 from the outside, and the rotating shaft 17 is screwed into the inside corner of the storage box 7.

Furthermore, a downward hook-shaped locking piece 11 is fixed to the center of the rear end surface of the seat plate 3, and at a position corresponding to the locking piece 11, on the rear side wall 72 of the storage box 7,
Locking devices 12 and 13, which are removable in the vertical direction, are fixed in respective directions, and the locking device 12 facing upward is engaged with the locking piece 11. On the other hand, the downward lock device 13 is engaged with and disengaged from a catch 18 fixed to the rear floor F of the storage box 7. Therefore, when the storage box 7 and the seat device 1 are all pulled up together to tilt them forward, the stopper 18 is left behind on the rear floor F as shown in FIG. It is placed in a recessed groove or the like where walking on this floor surface is not a hindrance.

The folding seat device configured as described above is
For example, as shown in FIGS. 5a, b, and c, the rear seats of the second row of the van-type vehicle 10 are installed on the floor F in the cargo compartment. The seat device 1 assembled as shown in FIG. and furthermore,
An upward locking device 12 is engaged between the storage box 7 and a locking piece 11 at the center of the rear end of the seat plate 3. At this time, the storage box 7 is used as a storage container for long and large items. Moreover, when folding the seat device 1,
As shown in Fig. 3, the seat backrest 2, seat plate 3, and storage box 7 are rotated forward in a three-layered state. The box 7 can be used as a storage space for long and large items in the same way as when used as a seat, and the stored items will not be scattered.

As described above, in this invention, the seat plate serves as the lid of the storage box, and the pivot point of the front legs of the seat and the pivot point of the front corner of the storage box are aligned concentrically or around the same axis. , are individually pivoted so as to be swingable back and forth, and the seat board and its lower surface, which corresponds to the lid body, and the edge stopper on the edge of the storage box are interposed as cushioning bodies, and the storage box is Since the locking device on the rear side wall is elastically engaged in the upper and lower directions, it does not come off involuntarily and has a reliable structure.

In addition, when folding the rear seats of a van-type vehicle to use a large floor area, the loading floor area can be expanded and extended by the area equivalent to the floor area of this storage box. This is a great idea with practical value.

Also, when opening the storage box as shown in Figure 2 and taking out and putting in the stored items, it is easy to remove the elastic engagement of the upward locking device and use the seatback as a handle. It can be opened and closed quickly, and only the seat can be reclined forward, exposing a storage box with a wide opening on the floor. Thus, the extra space directly below the seat plate of the seat device is made more useful. Furthermore, since the storage box itself is integrated with the seat cushion and can be tilted forward, the storage box will not move due to vibrations while the vehicle is running, making it safer. It has a huge effect.
