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. but,
When such a removable seat is incorporated into the main seat, what is required is a simple configuration that allows for easy attachment and removal operations, and that the presence of the removable seat does not impair the seating comfort of the main seat. It is necessary to make sure that there is no such thing.

In other words, this type of take-out sheet generally has
Consists of a seat cushion and a seat back that are embedded in the recesses provided in the seat cushion and seat back on the main seat side from the respective surfaces, and can be easily pulled out and used by the user when necessary. It is considered to be configured as follows.

By the way, since the above-mentioned take-out seat requires legs when in use, it is common practice to integrally incorporate foldable legs made of a pipe body under the seat cushion.
These legs touch the buttocks of the person sitting on the main seat, causing problems such as uncomfortable seating. 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 system with a simpler structure that can meet all of the requirements.

The present invention has been made in view of the above circumstances, and has a simple structure in which the legs are folded and held on the back side of the take-out seat cushion, and the legs are incorporated and held on the seat back side of the main seat. To provide a seat device that allows a removable seat to be incorporated into the main seat side without impairing the comfort of sitting on the main seat side, and which can also function as a removable seat during ejection.See the drawings below. It will become clearer as we explain in detail below.

1 to 3 show one embodiment of the seat device according to the present invention, and in these figures, reference numeral 1 is a main seat used as a vehicle seat, and a seat cushion 2 and a seat back are shown in FIGS. Although not shown, a reclining mechanism and a front-rear sliding structure may be added as additional functions as a seat.
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, recesses 4 and 5 for storing the take-out sheet 10 in a buried state are formed in a part of the main seat 1 in the seat cushion 2 and the seat back 3, respectively. A take-out sheet 10, which characterizes the present invention, is removably accommodated in these recesses 4 and 5 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 take-out sheet 10 is assembled on the seat bag 3 side of the main sheet 1, and the seat bag 12 is assembled on the seat cushion 2 side of the main sheet 1, and the legs 13, 14 are assembled. is configured to be foldably assembled to the seat frame 15 of the seat cushion 11 and accommodated on the main seat 1 side.

To explain this in detail, the legs 13 and 14 of the take-out seat 10 are entirely formed of pipe bodies bent into a substantially U-shape, and both ends thereof are on the front end side with respect to the seat frame 15 of the seat cushion 11. and the rear end side thereof, respectively, via screws or the like so as to be rotatable. And these both leg parts 13,1
When the sheets 4 are folded, they are held in a juxtaposed state on the back side of the seat cushion 11, as shown in FIG.

Further, in the seat frame 15 and leg portions 13, 14 of these seat cushions 11, horizontal pipe portions 15a, 15 that are horizontally suspended in the width direction of the seat are provided.
b; 13a; 14a are respectively curved and formed on the back side of the seat cushion 11, that is, on the seat back 3 of the main sheet 1, so as to protrude from the back side thereof;
Care has been taken to ensure that the back of the person seated on the main seat 1 does not come into contact with these pipe sections and cause discomfort.

In the figure, 16 is a seat frame on the side of the seat bag 12 of the take-out seat 10, and 17 is a connecting bracket that connects this seat frame 16 and the seat frame 15, which can be freely configured as a reclining mechanism. Furthermore, 18 in the figure is a seat spring.

Further, since the legs 13 and 14 mentioned above protrude to the back side of the seat cushion 11, the legs 13 and 14 are accommodated and held at the bottom of the recess 5 formed in the seat back 3 of the main seat 1. Groove 6
are provided at predetermined locations so that there will be no problem during installation.

Therefore, according to such a configuration, in the take-out seat 10, 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 seat cushion 11 is not seated as in the conventional case. The problem of the legs touching the person's buttocks and the feeling of sitting comfort is no longer caused, and the seat frame 15 of the seat cushion 11 and the legs 13, 14 of the seat cushion 11 in the take-out seat 10 are removed in the seat bag 3 of the main seat 1. Since the horizontal pipe portions of the main seat 1 are curved toward the back side, there is no problem of the seated person's back hitting these pipe bodies, and the seat performance as the main seat 1 can be maintained appropriately.

Further, according to the take-out sheet 10 having the above-described configuration, when the take-out sheet 10 is taken out from the main sheet 1, as shown in FIG.
After rotating the seat cushion 11 and seat back 12 to an appropriate state as shown in FIG. It is easy to complete and is not only excellent in terms of operability, but also has no problem in terms of strength. Here, when the legs 13 and 14 are opened, the stopper 19
It is obvious that if these are formed at both ends of the leg parts 13 and 14 as shown in FIG. 5, the function of the leg parts 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, the seat cushion 11 and the seat back 12 of the take-out sheet 10 may be assembled separately into the main sheet 1 and connected as appropriate during use. But it goes without saying that it's a good thing.

As explained above, according to the present invention, the seat cushion and foldable legs of the take-out sheet are removably incorporated into the seat back side of the main sheet, so despite the simple and inexpensive structure, Therefore, it is possible to obtain a seat device that can perform the necessary functions as a take-out seat and that has no risk of impairing seating comfort on the main seat side.
