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 notebook.

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 to compose.

In other words, this type of retrieval device is generally composed of a seat cushion and a seat back, and is embedded in the main seat side and seat back from the surface side, and can be removed when necessary. It is configured so that the user can easily pull it out and use it. By the way, since such a take-out sheet requires legs when it is used, it is possible to configure it so that foldable legs made of a pipe body are integrally incorporated into the lower side of the notebook cushion. This is a common practice, but with this type of structure, the lower legs of the seat cushion just hit the buttocks of the person sitting on the main seat, which can cause problems if the seating comfort deteriorates. 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 was made in view of these circumstances, and
A simple method is to hold the legs on both sides of the seat cushion, which is incorporated into a part of the seat cushion of the main sort, in an expanded state, and to store these legs in the storage section provided on the main seat side. Depending on the configuration, it is possible to incorporate a take-out seat without impairing the seating comfort on the main seat side, and to provide a seat device that can temporarily perform the necessary function as a take-out seat. It will become clear from the detailed description.

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 denotes a main seat, which includes a seat cushion 2 and a notebook bag 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 ring mechanism or may be of a fixed type.

In the above-mentioned main seat 1, the left and right sides of the seat cushion 2 and notebook bag 3 are equipped with the 7-tokutunyeon 11 and the notebook bag 12 that constitute the ejector:/-1-10 shown in FIG. Recesses 5° 5; 6, 6 are formed into the recesses 5° 5; 6, respectively, into which the recesses are embedded from the surface side. What should be noted here is that each of these four parts 5,
The removable seat 10 incorporated into the main seat 6 is assembled so as to correspond to the seating position of a person sitting on the main seat 1.

In fact, in the seat 2 of the master/to 1,
As shown in FIG. 1, both side parts and the center part other than the recessed parts 5, 5 are left and right lid bodies 7, which can be rotated to the left and right outer sides of the seat 1 and to the front of the seat 1, respectively. 8 and central lid body 9
The lids 7, 8; 9 are formed with accommodation spaces 7a, 8a; 9a that open toward the four parts 5, 5.

On the other hand, as shown in FIGS. 2 to 4, the take-out sheet is made of a substantially U-shaped pipe body that can be rotated to the left and right under the cushion 11. ,
Right leg portions 13, 14, and reinforcing lock levers 15a, 15b; 16a that intersect at the front and rear of these leg portions 13, 14 to connect both leg portions 13, 14.

1.6 b. And these leg parts 13,
14 and lock levers 15a, 15b; 16
a, 16b are the main parts 1 of this take-out sheet 10;
When assembled into the seat, as shown in FIGS. 1 and 2, it is unfolded toward both side portions of the seat, and
It is configured to be located on the same plane below the sheet 1. In addition, each of the lock levers 15a
, L5b; 16a and 16b each have one end pivotally supported under the legs 13 and 14, and the other end a pin 14a protruding from the opposite leg 14 or above the leg 13; 13a, a pin 17a is formed in the center of one side, and a notch 17b is formed in the other side to be locked to the pin 17a.

According to such a configuration, the legs 13, 14 of the above-mentioned takeout sheet IO, and furthermore, the lock L/bar 15a, 15b; 16a + 16b,
As is clear from FIG. 1, when assembled into the main seat 1, the storage spaces 7a, 8a; 9a for the left and right lids 7.8 and the center lid 9 that make up the /-tokseongyeon 2 are
Since the seat is housed and held within the seat and is incorporated into the accommodation 2, and its position is in a part where a seated person would not normally sit, there is no risk of the feeling of sitting comfort being impaired.

Open the left and right lids 7, 8 and center lid 9 of the notebook cushion 2 (as described above) to the outside of the sort as shown in FIG. 1, and take out the notebook 10. It's good and the work is easy. Then, the take-out/-t 1 taken out from the main sheet 1 in this way
0, its legs 13, 14 and lock lever
15a, 15b + 16a.

16b in Figures 2 and 3 (a) (b) (C)
As shown in the figure, all you have to do is move it sequentially and assemble it.
It is easy to understand that not only can the assembly work be easily performed, but also that it can be used in a state where it can be used 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 the shape, structure, etc. of each part may be modified or changed as appropriate without departing from the spirit of the present invention. It should be obvious. For example, in the above-mentioned embodiment, the take-out notebook 1
0 shows a case in which the seat cushion 11 and the notebook back 12 are integrally configured.1 to 1. However, the sorting back 12 may be incorporated into the main notebook 1 as a separate body, or a case without this seat back may be used. But of course it's a good thing.

Furthermore, the configuration of the leg portion of the extractor/tower 10 is not limited to the structure of the embodiment, and various modifications are possible.
It will be easily understood that it is possible to take out the notebook even if one of the main sort side storage sections that accommodates the legs does not have a lid structure.

As explained above, according to the present invention, the legs of the take-out sheet are expanded to both side portions and incorporated into the main sorting side, so that despite the simple configuration, the seat comfort of the main sheet is improved. It is possible to obtain a seat device equipped with a removable seat that can be easily attached and detached without causing any harm to people's senses.
