Description

[Detailed Description of the Invention] The present invention relates to a seat structure in which a take-out sheet is detachably incorporated into a part of the main seat, and the take-out sheet can be removed and taken out for use as needed.

2. Description of the Related Art There is a desire for a seat for a vehicle that can be partially removed and taken outdoors and used as a simple seat outdoors. What is required when incorporating this ejectable seat into the main seat is that its configuration and attachment/detachment operations are simple, while the structure is such that the comfort of the main seat is not impaired when the legs of the ejectable seat are stored. . The legs of the conventional take-out seat are made of foldable pipe bodies, and the legs in the folded state hit against the buttocks of the person sitting on the main seat, making the seat uncomfortable.

The purpose of this invention is to be able to easily and quickly take out the take-out sheet from the main sheet, to easily attach the legs without using any tools, and to be able to easily and quickly take out the take-out sheet from the main sheet. To provide a seat structure that does not deteriorate the seating comfort of the seat, can improve the cushioning properties of the main seat while being incorporated into the main seat, and can also be used as an air lifter. This will become clear from the detailed description below with reference to the drawings.

1 and 2 schematically show an embodiment of the seat structure according to the present invention, in which a part of the seat cushion 2 of the main seat 1 has a takeout seat
A seat cushion 12 of the main seat 1 is detachably assembled, and a seat bag 13 of the take-out seat 11 is detachably assembled into a part of the seat bag 3 of the main seat 1. Note that the height of this seat bag 13 is formed low.

The seat cushion 2 of the main sheet 1 is formed with a recessed part 4 for taking out the sheet, and the main sheet 1
The seat back 3 has a concave portion 5 for taking out the sheet.
The seat bag 3 can be provided with appropriate holding means for supporting the seat bag 13 of the take-out sheet 11. In this embodiment, the main seat 1 is shown as a bench-type seat, and a pair of take-out sheets 11 can be taken out from the main seat 1, but it is also possible to take out one take-out sheet 11 from a single main sheet. You may also do so.

Seat cushion 12 of the take-out sheet 11
As shown in FIG. 1, air support mats 16 as legs are attached to the bottom of the holder. This air support mat 16 is provided with an air injection valve 18 and an exhaust valve 19, which are connected to an air pump 17, respectively. The sheet cushion 12 of the take-out sheet 11 is a substrate 1 made of palm board or the like.
2a and a pad material 12b placed on the substrate 12a, and the substrate 12a is attached to a seat cushion frame 15. The air support mat 16 is attached to substantially the entire bottom surface of the seat cushion frame 15. Also, although not shown, air support mat 1
Substrates may be attached to the upper and lower surfaces of 6, respectively. Furthermore, an air injection valve 18 formed on the air support mat 16
In place of the injection valve 19 and the exhaust valve 19, an injection port and an exhaust port are integrally formed, and an air pump 17 is connected to the injection port and the exhaust port.
may be detachably connected.

As shown in FIG. 2, a housing portion 6 for an air pump 17 is formed on the side of the concave portion 4 of the seat cushion 2 of the main seat 1.
7 is housed, the seat cushion 12 of the take-out sheet 11 and the air support mat 16 as the legs are housed in the recessed part 4. When storing the air support mat 16, the exhaust valve 19 is opened to discharge the air inside the air support mat 16, and the upper surface of the seat cushion 12 of the take-out sheet 11 and the upper surface of the seat cushion 2 of the main sheet 1 are approximately the same. It is stored at the same height. When the air support mat 16 is housed in the recess 4 with the exhaust valve 19 closed with some air injected into the air support mat 16, the air support mat 16 can be used as a cushion body. It can also be used as an air lifter to adjust the height of the seating portion of the main seat 1 by adjusting the amount of air injected into the air support mat 16.

Further, the seat back 13 of the take-out seat 11 is attached to the seat cushion 12 so as to be tiltable back and forth, and when it is incorporated in the main seat 1, the seat back of the take-out seat 11 is tilted back and forth in response to the back and forth tilting of the seat back 3 of the main seat 1. 13 is also configured to be able to tilt back and forth, and a lock mechanism 21 that can maintain an appropriate inclination angle when the take-out sheet 11 is taken out from the main sheet 1 locks the seat cushion 12 of the take-out sheet 11 and the seat back 1.
3.

In this embodiment, the seat cushion 12 of the take-out sheet 11 and the seat bag 13 are attached as one body, but the seat cushion 12 and the seat bag 13 of the take-out sheet 11 may be separate bodies. They may be stored separately in the recesses 4 and 5 of the main sheet 1, taken out, and connected by a connecting member (not shown).

The above is the configuration of one embodiment of the seat structure according to the present invention.
1 as an independent simple seat, take it out from the concave part 5 of the seat cushion 3 of the main seat 1, tilt the seat back 13 of the sheet 11 forward, and then take it out from the concave part 4 of the seat cushion 2 of the main seat 1. Seat cushion 1 of take-out sheet 11
Take out 2. When the seat cushion 12 is taken out, the air support mat 16 serving as the bottom leg of the seat cushion 12 is taken out as a whole, and the air pump 17 is also taken out from the storage section 6.

After taking out the take-out sheet 11 outdoors, etc., operate the air pump 17 to inject air into the air support mat 16 with the exhaust valve 19 of the air support mat 16 as a leg closed, and the take-out sheet 11 is put into use. It can be done. Incidentally, if the seat bag 13 of the take-out sheet 11 is not integrated with the seat cushion 12, it is sufficient to assemble them together, and it is also possible to use the seat bag 13 without the seat cushion 12.

According to the present invention, it is possible to easily and quickly take out the takeout sheet from the main seat and use it outdoors, etc., outside the vehicle, by simply injecting air into the air support mats that serve as the legs of the takeout seat. It can be set to the desired height, making it easy to form the legs, and when it is assembled into the main seat, the air support mats that serve as the legs of the take-out seat have cushioning properties, so they do not worsen the sitting comfort of the main seat. Moreover, by adjusting the amount of air in the air support mat, it can be used as an air lifter, and a seat structure that can significantly improve seating comfort can be obtained.
