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 configured to be removable, the removed seat can be taken outdoors and used as an auxiliary seat, which is highly useful. However, when incorporating such a take-out sheet into the main seat, what is required is that its configuration and attachment/detachment operations are simple, and that the presence of the take-out sheet does not impair the sitting comfort of the main seat. It is necessary to configure it as follows.

In other words, this type of take-out sheet generally has
It 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 is configured so that the user can easily pull it out and use it when necessary. There is. By the way, in the case of such a take-out seat, since legs are required when using the seat, it is preferable to configure the seat cushion so that foldable legs made of a pipe body are integrated into the lower side of the seat cushion. However, with this structure, the lower legs of the seat cushion hit the buttocks of the person sitting on the main seat, causing problems such as making the seat uncomfortable. There is. 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 that some kind of countermeasure be taken to satisfy all the conditions.

The present invention has been made in view of the above circumstances, and consists of holding legs in an expanded state on both sides of the seat cushion of a take-out sheet, which is incorporated into a part of the seat cushion of the main sheet. With a simple configuration in which the parts are housed in storage parts provided on both sides of the seating part of the seat cushion of the main seat, it is possible to incorporate the removable seat without impairing the feeling of sitting comfort on the main seat side, and it also provides side support. The purpose is to provide a seat device that can improve the functionality and perform the necessary functions as a take-out seat during take-out, as will become clear from the detailed description below with reference to the drawings. .

FIGS. 1 and 2 show an embodiment of the 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 that is generally used as a rear seat.

In these figures, reference numeral 1 is a main seat, comprising a seat cushion 2 and a seat back 3,
It is installed on the floor surface of the vehicle body (not shown) with a pair of legs 4a and 4b. 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 sheet 1, on both the left and right sides of the seat cushion 2 and seat back 3, there are seat cushions 11 and seat backs 12 that constitute the take-out sheet 10 shown in FIG.
Concave portions 5, 5; 6, 6 are formed into which the components are embedded from the surface side, respectively. What should be noted here is that the takeout sheet 10 incorporated into each of these parts 5 and 6 is assembled so as to correspond to the seating position of a person sitting on the main seat 1.

In addition, in the seat cushion 2 of the main sheet 1, both side parts and the center part other than the recessed parts 5, 5 are respectively connected to the seat cushion 2, as shown in FIG.
It is formed by left and right lids 7, 8 and a center lid 9 that can be rotated to the left and right outside and to the front of the seat 1, and these lids 7, 8; 9 have the recesses 5, 5. Accommodation spaces 7a, 8a; 9a are formed which are open to the sides.

On the other hand, the take-out sheet 10 has a sheet cushion 11 as shown in FIGS. 2 to 4.
The left and right legs 13 and 14 are made of substantially U-shaped pipe bodies that can rotate in the left and right directions on the lower side, and the legs 13 and 13 intersect at the front and rear of these legs 13 and 14. , 14 for reinforcement.
5a, 15b; 16a, 16b. These leg portions 13, 14 and lock levers 15a, 15b; 16a, 16b are attached to both side portions of the sheet as shown in FIGS. The seat cushion 11 is unfolded and positioned below the seat cushion 11 in the same plane. In addition, each of the lock levers 15
a, 15b; 16a, 16b is a pin 14a, 13a whose one end is pivotally supported under the legs 13, 14, and whose other end projects above the opposite leg 14 or 13. It is formed as a hook part that is locked to the
7a, and a notch 17b that is locked on the other side.
is formed.

According to such a configuration, the legs 13 and 14 of the above-mentioned takeout sheet 10, and further the lock levers 15a and 15b; 16a and 16b.
As is clear from FIG. 1, when assembled into the main seat 1, the left and right lids 7, 8 and the center lid 9, which constitute the seat cushion 2, are housed in the housing spaces 7a, 8a; 9a. It is held and incorporated into the seat cushion 2, and its position is in a part where the seated person does not normally sit.
There is no risk that the feeling of sitting comfort will be impaired. Furthermore, the left and right lids 7, 8 and the center lid 9 can function as side supports.

In addition, the left and right lids 7 and 8 and the center lid 9 of the seat cushion 2 of the main seat 1 described above are
As shown in the figure, it is preferable to open the sheet to the outside and take out the take-out sheet 10, and this operation can be easily performed. Then, in the takeout sheet 10 taken out from the main sheet 1 in this way, its legs 13, 14 and lock levers 15a, 1
5b; 16a and 16b can be assembled by sequentially moving them as shown in FIG. 2 and FIG. It will be easily understood that the usage condition is excellent in terms of strength as shown in FIG. 4.

It should be noted that the structure of the embodiment described above 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, in the embodiment described above, the seat cushion 11 and the seat bag 12 are integrally constructed as the take-out sheet 10, but the seat bag 12 may be incorporated into the main sheet 1 as a separate body. Of course, it is also possible to use one without this seat back.

Further, the configuration of the leg portions of the take-out sheet 10 is not limited to the structure of the embodiment, and various modifications are possible, and one of the main sheet-side accommodating portions that accommodates the leg portions may have a lid structure. It will be easily understood that it is possible to take out the sheet at least.

As explained above, according to the present invention, the legs of the take-out sheet are expanded to both side portions and incorporated into both sides of the seating portion of the seat cushion of the main sheet. Regardless, it is possible to obtain a seat device equipped with a removable seat that does not impair the sitting comfort of the main seat, allows the legs of the removable seat to be used as side support for the main seat, and can be easily attached and detached. can.
