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, 1-1 When incorporating such a take-out sheet into the main sheet, what is required is that its structure and attachment/detachment operations are simple, but the existence of legs etc. of this take-out sheet makes it difficult to use the Senshu sheet. The structure should be such that it does not make the seat uncomfortable.

That is, this type of removable seat generally consists of a seat cushion and a seat back, and is embedded in the seat cushion and seat back on the main seat side from the surface side, respectively, and can be used when necessary. It is structured so that a person can easily use the drawer i-. By the way, since such a retrieval sheet requires legs when in use, it is possible to construct the sorting cushion so that foldable legs made of a pipe body are integrated into the lower side of the sorting cushion. This is commonly done, but with this structure, the lower part of the legs folded under the seat cushion hits the buttocks of the person sitting on the main seat, making the main seat uncomfortable. It's causing problems. 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 strong structure. It is desired to take some measures that can satisfy all of these conditions.

The present invention was made in view of these circumstances, and
The right leg is held in an inverted state on the left side of the seat cushion of the takeout notebook that is incorporated into a part of the seat cushion of the main seat 1, and the left leg is held on the right side in an inverted state. To provide a seat device in which a take-out sheet can be incorporated without impairing the comfort of sitting on the main seat side by having a simple configuration in which the seat is housed in a storage section, and which can perform the necessary function as a take-out sheet when taking out the seat. This will become clear from the detailed description below with reference to the drawings.

FIGS. 1 to 3 each schematically show an embodiment of a seat device according to the present invention, and this embodiment shows a case where the seat device is applied to a bench-type vehicle seat generally used as a rear seat. ing.

In these figures, reference numeral 1 denotes a main notebook, comprising a seat cushion 2 and a seat back 3, and a pair of legs 4a.
, 4b are installed on the vehicle body floor (not shown). It goes without saying that the main seat 1 may have a reclining mechanism in which the seat back 3 can be tilted back and forth, or it may be of a fixed type.

In the above-mentioned main seat I, seat cushions 11 constituting the take-out seat 10 shown in FIG.
and the seat back 12, '& (-) are formed with recesses 5, 5; 6, 6, which are to be embedded in from the surface side of the recesses 5, 6.6. The removable seat 10 that can be assembled and folded is assembled so as to correspond to the seating position of a person sitting on the main seat 1.

FIG. 2 shows a usage state in which the take-out seat 10 is taken out from the main seat 1, and a pair of legs 13 and 14 are provided on both sides of the seat cushion 11 of the take-out seat 10 on the front and rear sides of the seat cushion 11. It is rotatably supported by a bracket 15 provided at a substantially central position. The pair of legs 13 and 14 are formed in a U-shape when viewed from the side, and have a trapezoidal overall shape when viewed from the front. The ends of the horizontal rod portions 13a, 14a formed at both ends of the pair of legs 13, 14 are connected to the bracket 15.
is pivotally supported by a pivot pin 16.

The pair of legs 13 and 14 are arranged so that the horizontal rods 1.3a and 114 hold the notes 11 and 11. Also, one horizontal rod portion 13a
Its length is longer than the length of the other horizontal rod portion 14a, and is formed so that the other leg portion 14 can pass through the inside of one leg portion 13.

Therefore, this pair of legs 1.3, 14 is housed as shown in FIG. That is, by rotating the pair of legs 13 and 14 by approximately 180 degrees, the right leg 14 can be placed on the left side of the seat cushion 11, and the left leg 13 can be placed on the right side. Note that cutouts 11a are formed on both sides of the seat cushion 110 in which the lower portions of the pair of legs 13 and 14 are accommodated. With the pair of legs 13 and 14 stored in the notch 11a of the seat cushion 11, the extraction sheet 10-7-Tokutsunoyon 11
When the main seat 1 is housed in the recess 5 of the main seat 1, the pair of legs 13 and 14 can improve side support for the seated person.

Incidentally, in the embodiment described above, the pair of leg portions 13° and 14
is shown as having a trapezoidal shape when viewed from the front,
The shape is not limited to this, for example, it can be formed into a circular arc shape, and various other modifications can be made. Also, a bracket 15 may be provided for each leg 13, 1.4. Furthermore, although the seat cushion 11 and the seat back I2 are integrally constructed as the removable seat 10, the seat back 12 can also be incorporated into the main seat 1 as a separate part, and the seat back 12 may not be provided. But that's fine.

The above is the configuration of one embodiment of the seat device according to the present invention. According to such a configuration, the takeout sheet 10 is assembled into the main seat 1, that is, the state shown in FIG. 3
As shown in the figure, if the take-out sheet 10 is taken out from the main sheet 1 and the pair of legs 13 and 14 are rotated approximately 180 degrees to open the legs, the take-out sheets 1 to 10 can be used immediately as shown in Fig. 2. It is possible to make it possible.

According to the present invention, the right leg is held in an inverted state on the left side of the seat cushion of the take-out seat which is incorporated into a part of the seat cushion of the main seat, and the left leg is held on the right side in an inverted state. With the simple structure of storing the seat in the storage section provided on the side, the removable seat can be incorporated without impairing the seating comfort window on the main seat side, and the lower part of the pair of legs can improve side support. Furthermore, it is possible to obtain a seat device that can fully perform the necessary functions as a take-out sheet during take-out.
