It is supported by the seat back 3 of the main seat 1 by a support structure fitted to the stay 10 of 9.

The seat apparatus of this first embodiment is used as follows.

When using the take-out sheet 11 as an independent sheet from the usage state in which the take-out sheet 11 is incorporated into the main sheet 1, the seat cushion 12 of the take-out sheet 11 is changed from the seat cushion 2 and the seat back 3 of the main sheet 1. Remove the seat bag 13 and take it outdoors, and then open the legs 16 and 17 of the front and rear devices provided at the bottom of the seat cushion 12 of the take-out seat 11 as shown in FIGS. 6 and 7, respectively. The support holes 20 formed at the lower end of the seat bag 13 are fitted into the protrusions 17c of the legs 17 of the rear device at the bottom of the seat cushion 12, and the backrest is fixed as shown in FIGS. 3 and 4. Use by assembling into a molded sheet.

In this manner, when assembling the takeout sheet 11 into an independent sheet, the legs 16 and 17 are opened as described above, and the support formed on the seat back 13 is attached to the protrusion 17c of the leg 17 of the rear device. The seat cushion 12 and the seat bag 13 can be extremely easily and strongly connected by simply fitting the holes 20 together.

Then, if necessary, the head rest 9 is removed from the seat bag 3 of the main sheet 1 and inserted into the support hole 21 formed at the upper end of the seat bag 13 of the take-out sheet 11, thereby using the take-out sheet 11 as a sheet with a head rest. can do.

Next, when returning the take-out sheet 11 to the main sheet 1, the sheet back 1 of the take-out sheet 11 is
3, remove the seat back 13 from the legs 17 of the rear device of the seat cushion 12 of the take-out seat 11, and
Fold the legs 16 and 17 and take out the sheet 11
A seat cushion 12 and a seat back 13 are placed in recesses 4 and 5 formed in the seat cushion 2 and seat back 3 of the main seat 1, respectively. Then, the seat cushion 12 of the take-out sheet 11 is fitted into the fitting parts 6 and 7 formed in the recessed part 4 with the protrusions 16b of the legs 16 and 17 folded at the bottom of the seat cushion 12.
7c, fix the device, and install it. Also,
The seat back 13 of the take-out sheet 11 is formed by fitting the support hole 21 formed at the lower end of the seat back 13 into the protrusion 8 provided at the lower end of the seat back 3 of the main sheet 1. Insert the stay 10 of No. 9 and take out the end of this stay 10 and remove the sheet 11.
The main seat 1 is assembled into the seat back 3 of the main seat 1 by fitting into the support hole 21 formed at the upper end of the seat back 13 of the main seat 1.

In this way, the seat cushion 2 of the main seat 1
Through the fitting between the fitting parts 6 and 7 formed in the recessed part 4 and the protrusions 16b and 17c of the legs 16 and 17 folded at the bottom of the sheet cushion 12 of the take-out sheet 11, Take-out sheet 11
The seat cushion 12 of the main sheet 1 can be easily and strongly connected to the protrusion 8 provided at the lower end of the seat back 3 of the main sheet 1, and the support hole 20 of the lower end of the seat back 13 of the take-out sheet 11. The support structure in which the main seat 1 is fitted, and the support hole 21 at the upper end of the seat back 13
The seat back 13 of the take-out sheet 11 can be easily and strongly connected to the support structure in which the stay 10 of the head rest 9 attached to the seat back 3 of the sheet is fitted.

In a state of use in which the take-out sheet 11 is integrated into the main sheet 1, the seat cushion 2 and the seat bag 3 of the main sheet 1 are combined with the seat cushion 12 of the take-out sheet 11 and the seat bag 1.
3 are incorporated separately, the reclining function of the seat back 3 of the main seat 1 is not impaired at all.

Next, FIGS. 9 and 10 show the second embodiment of the present invention.
An example is shown below.

This embodiment differs from the first embodiment in that the legs 22 and 23 attached to the front and rear devices at the bottom of the seat cushion 12 of the take-out sheet 11 are different from those of the first embodiment.
have different shapes.

That is, the legs 22 of the front device are connected to the main body 22a.
and a protrusion 22b provided approximately at the midpoint in the length direction, and the leg portion 23 of the rear device
It has a crank shape having a main body 23a, a connecting piece 23b, and a protrusion 23c. As shown in FIG. 10, the protrusion 23c of the leg portion 23 has:
The support hole 20 formed at the lower end of the seat bag 13 of the take-out sheet 11 can be fitted into the take-out sheet 11 when the legs are opened.

The concave portion 4 of the seat cushion 2 of the main seat 1 has a fitting portion 24 into which the protrusion 22b of the leg portion 22 is fitted, and a fitting portion 25 into which the protrusion 23c of the other leg portion 23 is fitted. are formed, and as shown in FIG.
The seat cushion 12 of the take-out sheet 11 is assembled into the seat cushion 2 of the main sheet 1 by fitting them into each other.

Note that the other configurations and functions of this second embodiment are the same as those of the first embodiment.

In the present invention, the support structure for the upper end of the seat bag 13 of the takeout sheet 11 with respect to the seat bag 3 of the main sheet 1 is such that the stay 10 of the head rest 9 attached to the main seat bag 3 is inserted into the support hole 21 formed in the seat bag 13. It is not limited to those that fit together.

Further, the support structure for fitting the protrusions on the legs of the take-out sheet 11 with the support holes at the lower end of the seat back 13 is not limited to two locations in the lateral direction of the take-out sheet 11, but may be provided at three or more locations. Good too.

The above is the configuration of one embodiment of the seat device according to the present invention. According to this configuration, the seat cushion and seat back of the seat taken out from the main seat can be removed and taken outdoors, etc., and the bottom part of the seat cushion can be removed. It can be assembled by simply opening the legs attached to the front and rear devices and fitting the protrusions provided on the legs of the rear device into the support holes formed in the lower end of the seat bag. It has the advantage that it can be easily assembled and used without using any.

Further, according to the present invention, the seat cushion of the take-out sheet is inserted into the seat cushion of the take-out sheet through a support structure that fits into the protrusion of the leg of the rear device at the bottom of the seat cushion of the take-out sheet. The seat back of the main sheet and the seat back of the take-out sheet can be strongly connected to each other. The upper end of the seat back of the main sheet is connected to the support structure that supports the upper end of the seat back of the take-out sheet, so these members can be strongly connected with a simple structure. be.

Moreover, according to the present invention, the seat cushion and seat bag of the main sheet are separately assembled into the seat cushion and seat bag of the take-out sheet, so that when the take-out sheet is incorporated, the main sheet cannot be used. It has the effect that it can be used without impairing the reclining function at all.

It should be noted that the above description merely shows one embodiment of the present invention, and it will be obvious that various modifications and changes can be made without departing from the spirit of the present invention.
