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, when incorporating such a take-out sheet into the main seat, it is required that the take-out sheet be configured so that it can be easily attached and removed, but that the presence of the take-out sheet impairs the comfort of sitting on the main seat. We must make sure that this does not happen.

That is, this type of take-out sheet 1 is
As shown in the figure, it consists of a seat cushion 5 and a seat back 6, etc., which are embedded in the seat cushion 3 and seat back 4 of the main seat 2 from the front side, respectively, and can be easily pulled out by the user when necessary. The idea is to make it available for use. In such a take-out sheet 1, the seat cushion 5 and the seat bag 6 may be assembled in a connected state in advance, or they may be connected with a simple connector (not shown) after each is taken out. It's also good.

By the way, since the above-mentioned take-out sheet 1 requires legs when in use, it is configured such that foldable legs 7a and 7b made of pipe bodies are integrally incorporated into the lower side of the seat cushion 5. This is generally done, but these legs 7
Since the points a and 7b touch the buttocks of the person sitting on the main seat 2, there is a problem in that the sitting comfort is worsened. However, such leg portions 7a,
7b is an important part of the above-mentioned take-out sheet 1 in order to maintain stability during use,
Since strength is also required, a somewhat robust structure is required, and it is desired to take some measures that can satisfy all of these requirements.

The present invention has been made in view of the above circumstances, and provides a seat cushion for a take-out sheet that is incorporated into a part of the seat cushion of the main seat, with an assembly leg section folded and stored at the lower front end of the seat cushion. To provide a seat device in which a take-out sheet can be incorporated without impairing the feeling of sitting comfort on the main seat side through a simple structure of holding the main seat, and which can also function as a take-out sheet when taking out the seat. , will become clearer from the detailed description below with reference to the drawings.

FIGS. 2 and 3 show an embodiment of the seat device according to the present invention, and only show the take-out seat 1, which is the main part, and the same or corresponding parts as in FIG. 1 are shown. Reference numerals are given and detailed explanation thereof will be omitted.

Now, according to the present invention, the seat cushion 5 of the take-out sheet 1 is characterized in that an assembly type leg section, generally designated by the reference numeral 10, is folded and stored and held at the lower part of the front end side of the seat cushion 5. There is.

In detail, this assembly type leg part 10 includes a support bracket that is screwed to the left and right lower portions of the front end of the seat frame (not shown) in the seat cushion 5 of the takeout sheet 1. Left and right pipe bodies 12 and 13 each having a substantially L-shape, one end of which is rotatably supported by 11a and 11b.
and a substantially U-shaped connecting pipe body 14 that is assembled to the other ends of these left and right pipe bodies 12 and 13. This connecting pipe body 14 has protruding pins 15a protruding from both ends thereof.
15b are fitted into the pin holes 16a, 16b on the left and right pipe bodies 12, 13, so that assembly can be easily performed, as is clear from FIG. 3. It will be easily understood that the pins and pin holes of the connecting portions between the left and right pipe bodies 12, 13 and the connecting pipe body 14 may be reversed from those in the above embodiment. Furthermore, 1 in Figure 3
Reference numeral 7 denotes a connector that connects the seat cushion 5 and the seat bag 6.

Furthermore, when the take-out sheet 1 is not in use, the connecting pipe body 14 is removed from the left and right pipe bodies 12, 13, and is oriented in the opposite direction, as is clear from FIG. It is configured to be elastically held by a holding bracket 18 provided at the lower center of the front end of the seat cushion 5.

Therefore, according to the take-out sheet 1 having such a structure, when it is assembled into the main seat 2 as shown in FIG. The assembly leg part 10 is located at the lower part of the front end side of the seat cushion 3 of the main seat 2, and the assembly leg part 10 assembled to the seat cushion 5 hits the buttocks of the seated person 20, providing a feeling of sitting comfort. The problem of damage to the material is eliminated, and there is no problem in assembling or strength during use.

It should be noted that the structure of the above-described embodiment 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 take-out sheet 1, the seat cushion 5 and the seat bag 6 are separately separated and assembled into the main sheet 2, and in particular, the seat cushion 5 with the sectional legs 10 is attached to the seat of the main sheet 2. Cushion 3
If it is assembled into the front end of
The configuration and division structure of 0 can also be changed as appropriate. The point is that the assembly type legs 10, which can stably support the take-out sheet 1, are collected and held at the front end side of the seat cushion 5 when assembled to the main seat 2, so that the sitting comfort of the main seat 2 is not impaired. Of course, a type of take-out sheet without the seat bag 6 may also be used.

As explained above, according to the present invention, in the take-out seat that is incorporated into a part of the seating portion of the seat cushion of the main seat, the legs are assembled and folded under the front end of the seat cushion for storage and storage. In addition, the legs of the take-out sheet are positioned at the bottom of the front end side of the seat cushion of the main sheet, so that the function required as a take-out sheet can be achieved despite the simple and inexpensive configuration. At the same time, there is no risk of impairing the sitting comfort of the main seat, and the legs of the take-out seat stored in the lower part of the front end of the seat cushion of the main seat function as thigh support for the seated person. It is possible to obtain a seat device that can improve seating comfort.
