Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a seat structure in which a take-out sheet is removably incorporated into a part of a main seat, and the take-out sheet can be removed and taken out as necessary for use.

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 at the same time ensuring that the seating comfort of the main seat is not compromised 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 touch the buttocks of the person sitting on the main seat, making the seat uncomfortable.

The purpose of the present 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 tools, and to be able to easily and quickly take out the take-out sheet from the main sheet, and to be able to easily attach the legs without using tools. This provides a seat structure that does not deteriorate the seating comfort of the seat, which 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 take-out sheet 1 is attached to a part of the seat cushion 2 of the main seat 1.
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.

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, a leg portion 16 is attached to the bottom of the holder at approximately the center position. This leg portion 16 is formed by a column 17 extending downward in a substantially vertical direction.
and a base 18 which is detachably attached to the lower end of the column 17, and the upper end of the column 17 is attached to a flat seat cushion frame 14. When the take-out sheet 11 is removed, the base 1
8 can be attached and used.

In this embodiment, the support 17 and the base 18 can be attached and detached using a male thread 19 formed on the outer periphery of the lower end of the support 17 and a female thread 2 formed approximately in the center of the base 18.
Although this is done by screwing with the locking mechanism 0, the locking mechanism is not limited to this, and an appropriate locking mechanism may be provided. Further, although the base plate 18 is shown as having a circular shape, it can also be formed in a rectangular shape.

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 13 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 when the take-out sheet 11 is taken out from the main seat 1, a lock mechanism 21 that can maintain an appropriate inclination angle locks the seat cushion 12 of the take-out sheet 11 and the seat back 1.
3.

A through hole 6 is formed in the concave portion 4 of the seat cushion 2 of the main sheet 1, through which the leg portion 16 of the takeout sheet 11 can be inserted.

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, and then taken out and connected by a connecting member (not shown).

When the take-out sheet 11 is incorporated into the main sheet 1, that is, when the take-out sheet 11 is not in use,
As shown in FIG. 2, after the male screw 19 formed on the outer periphery of the lower end of the support column 17 and the female screw 20 formed in the center of the base plate 18 are released, the base plate is pulled out from the lower end of the support column 17. The seat cushion 2 of the main seat 1 is moved again from the lower end of the support 17 toward the upper end of the support 17 with the bottom 18a of the support 18 facing up, and is screwed onto the male thread 22 formed at the upper end of the support 17. By inserting the support 17 into the through hole 6 formed in
This can prevent the take-out sheet 11 from moving or shifting in the front-back and left-right directions.

In addition, in the above embodiment, the bottom part 18 of the base 18
It is configured so that the take-out sheet 11 can be stored facing the lower part of the sheet cushion frame 14 with a facing upward, and the bottom 18a of the base 18 of the take-out sheet 11 does not stain the concave portion 4 of the main sheet 11. In addition, when the take-out sheet 11 is taken out from the main sheet 1, the support 17 is
Although the structure is configured to be screwed into the male thread 22 formed at the upper end, the main point is that the base 18 can be detachably attached to the lower end of the support column 17, and the base 18 can be attached to the recessed part 4.
It suffices if it is configured so that it can be stored in.

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 back 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 taking out the seat cushion 12, since the struts 17 of the legs 16 at the bottom of the seat cushion 12 are inserted into the through holes 6 of the recessed portions 4 of the seat cushion 2 of the main seat 1, the seat cushion 12 is pulled up in approximately the same direction. Take it out like this.

After taking out the take-out sheet 11 outdoors etc., if the female thread 20 of the base 18 of the leg part 16 and the male screw 19 at the lower end of the support column 17 are screwed together, the take-out sheet 11 can be removed.
can be put into use. Note that the seat bag 13 of the take-out sheet 11 is the seat cushion 1.
If they are not integrated with 2, they can be assembled together.

Next, when returning the takeout sheet 11 to the main sheet 1, the base 18 of the leg portion 16 of the sheet cushion 12 is placed in a state where it can be stored in the recess 4 or 5,
The support column 17 is inserted into the through hole 6 of the seat cushion 2 of the main sheet 1, and the concave portion 4 of the seat cushion 2 is inserted.
The seat bag 13 is stored in the concave portion 5 of the seat bag 3 of the main seat 1.

According to the present invention, the takeout sheet can be easily and quickly taken out from the main seat and used outdoors outside the vehicle.In this case, the legs of the takeout sheet only need to be attached to the base on the support, and The forming work is easy, and since the main seat is supported using the support of the mounting seat, it can be done reliably and strongly, and the legs of the take-out seat do not worsen the sitting comfort of the main seat, improving the seating comfort. It is possible to obtain a seat structure that allows for flexible seating.
