Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a seat device in which a takeout sheet is detachably incorporated into a part of a main seat.

For example, if a part of a vehicle seat is made removable, the removed seat can be taken outdoors and used as an auxiliary seat, which is highly useful. However, when incorporating a removable seat such as No. 9 into the main seat, what is required is a simple configuration, easy attachment and removal operations, and the presence of the removable seat to improve the seating comfort of the main seat. It is necessary to ensure that it does not harm the

That is, this type of removable seat generally consists of a seat cushion and a seat back that are embedded in recesses provided in the seat cushion and seat back on the main seat side from the surface side, respectively, and It is considered to be constructed so that the user can easily pull it out and use it when necessary.

By the way, since the above-mentioned removable seat requires legs when in use, it is common practice to incorporate foldable legs made of a pipe body into one body under the seat cushion. Since these legs contact the buttocks of the person sitting on the main seat, problems arise when the seat feels uncomfortable. However, such legs are important for maintaining the stability of the above-mentioned take-out sheet during use, and their strength is also required, so they require a somewhat robust structure. There is a desire for a seat device with a simpler structure that can meet all of the requirements.

The present invention was made in view of these circumstances, and
Retrieval 1 - A simple configuration in which the legs are folded and held on the back of the seat cushion of the seat, and the legs are assembled and held on the seatback side of the main seat, does not impair the comfort of the seat on the main seat side. The purpose of this invention is to provide a seat device in which a take-out notebook can be incorporated into the main seat side and which can function as a take-out sheet when taking out notebooks.This will become clear from the detailed description below with reference to the drawings. .

1 to 3 show one embodiment of the seat device according to the present invention, and in these figures, reference numeral 1 denotes a main seat used as a vehicle seat, and seat cushions 2 and 3 are shown in FIG. It consists of a seat back 3, etc., and may also be provided with a reclining mechanism and a back-and-forth sliding structure as an accessory function as a notebook (not shown).

Here, although a bench-type main seat 1 is shown in this embodiment, it is clear that the main seat 1 is not limited to this.

As shown in FIG. 1, in a part of the main seat 1, there are recesses 4 and 5 for storing the take-out sheet 1O in a buried state between the seat back 2 and the seat back 3. In the recesses 4 and 5, a takeout 10, which characterizes the present invention, is removably accommodated in the recesses 4 and 5, respectively, in the state shown in FIG.

What should be noted here is that according to the present invention, contrary to the conventional device, the seat cushion 11 of the takeout seat 10 is placed on the seat back 3 side of the main seat 1, and the seat cushion 11 is placed on the side of the seat back 3 of the main seat 1.
2 is assembled on the seat cushion 2 side of the main seat 1, and its legs 1.3 and 14 are assembled to the seat frame I5 of the seat shoe 11 so that they can be folded freely. be configured to accommodate.

To explain this in detail, the legs 13 of this takeout sheet 10
, 14 consists of a pipe body bent into a generally U-shape, and both ends of the pipe body are connected to the seat frame 15 of the seat cushion 11 on the front end side and the rear end side of the seat frame 15 through screws or the like. It is movably mounted. When the legs 13 and 14 are folded, they are held in parallel on the back side of the seat cushion 11, as shown in FIG.

Also, seat frame 1 of Torera Note Kutsuyeon 11
5 and leg portions 13, 14, horizontal pipe portions 15a, 15b; 13a;
a is curved so as to protrude from the back side of the sorting cushion 11, that is, the main seat 10 and the sorting bag 3, and the back of a person seated on the main seat 1 hits each of these pipe parts, causing a strange feeling. Care has been taken to ensure that this does not happen.

In addition, 16 in the figure is the seat back 12 of the notebook 10 to be taken out.
1111117) Seat frame 17C is a connection bracket that connects the seat frame 16 and the sorting frame 15, and it is free to configure this with a reclining mechanism. Furthermore, 18 in the figure is a seat spring.

In addition, the legs 13 and 14 mentioned above are
1, the leg portion 13 is located at the bottom of the recessed portion 5 formed in the sorting back 3 of the main tray 1.
, 1.4 is provided at a predetermined lock point, and the groove portion 6 is configured such that it does not cause any trouble during installation.

Therefore, according to such a configuration, the take-out sheet 1
0, the seat cushion 11 to which the legs 13 and 14 are attached is incorporated into the seat back 3 side of the main seat 1, so that the legs do not come into contact with the seated person's buttocks as in the past.
There is no longer a problem that the seating comfort is impaired, and furthermore, the main seat 107 - the seat 10 can be removed from the
Since the seat frame 15 and the horizontal pipes of the legs 13 and 14 of the seat cushion 11 are curved toward the back side, there is no problem of the seated person's back hitting these pipes, and the seat cushion 11 can be used as the main seat 1. It becomes possible to maintain sheet performance appropriately.

In addition, according to the take-out seat (10) having the above-mentioned configuration, the main seat 1 is taken out and the seat cushion 11 and seat back 12 are rotated to an appropriate state as shown in FIG. 4(a). After that, as shown in FIG. 2(b), just rotate both legs 13 and 14 in the opening direction.

Easy to assemble, but also photon. A. It is not a stupid thing that has excellent operability, and there is no problem in terms of strength. Here, these legs 13.

It will be obvious that if the stoppers 19 when the legs 14 are opened are formed at both ends of the legs 13 and 14 as shown in FIG. 5, the function as the legs can be obtained. Of course, various modifications can be considered as such a locking means, and it is not limited to the embodiment.

It should be noted that the structure of the above-described embodiment merely shows one embodiment of the present invention, and it is obvious that the shape, structure, etc. of each part can be modified and changed as appropriate without departing from the spirit of the present invention. For example, a seat cushion 11 and a seat back 12 (10 seat cushions 11 and 12) may be installed separately in the main seat 1 and connected as appropriate during use. Needless to say, a type sheet may also be used.

As explained above, according to the present invention, the seat back side K of the main seat, the seat cushion of the take-out seat, and the foldable legs are detachably assembled.
Despite having a simple and inexpensive configuration, it is possible to obtain a seat device that can perform the necessary functions as a take-out seat and has no risk of impairing seating comfort on the main seat side.
