本考案はエヤ袋内蔵シート、特にエヤ袋に空気
を供給する機構に関するものである。[Detailed Description of the Invention] The present invention relates to a sheet with a built-in air bag, and particularly to a mechanism for supplying air to the air bag.
従来、第１図に示すようにシート１はそのフレ
ーム２側とこのフレーム２の上部側を被う緩衝材
３との間にエヤ袋４を内蔵したものが提案されて
いる。 Conventionally, as shown in FIG. 1, a seat 1 has been proposed in which an air bag 4 is built in between the frame 2 side of the seat 1 and a cushioning material 3 covering the upper side of the frame 2.
上記空気袋４は、ほぼ身体５の全体を保持する
ことができる程度の大きさに設定されている。し

場合には、身体５に傾きが生じた場合この傾きが
生じた側Ａの空気が反対方向に逃げてしまい、こ
の部分Ａ側の保持力が増々小さくなるので、身体
５がさらにＡ方向に傾いてしまい保持機能を発揮
することができなくなるという欠点を有してい

ブにおいて身体に常時傾が生じるのであるが、こ
の傾きがさらに助長されてしまい運転に支障をき
たすことになる。 The air bladder 4 is set to a size that can hold almost the entire body 5. However, when constructed from one air bag in this way, if the body 5 is tilted, the air on the side A where this tilt occurs will escape in the opposite direction, and the holding force on this side A will become smaller and smaller. As a result, the body 5 is further tilted in the direction A, resulting in a disadvantage that the holding function cannot be exerted. Therefore, such a seat 1 is not suitable for a vehicle seat, etc., which requires the user to firmly hold the body. That is, when applied to a vehicle seat, the body is always tilted when the vehicle is driving around a curve, and this tilt is further exacerbated, causing trouble in driving.
従つて、第２図に示すように身体５の全体を保
持するエヤ袋を複数のエヤ袋１０，，１１から形

る場合、空気が押圧力が与えられないエヤ袋１０
側に多量に供給され空気が平等に供給されないこ
とになり、エヤ袋１１の保持力が低下してしまう
という欠点を有する。 Therefore, as shown in FIG. 2, it has been proposed that an air bag for holding the entire body 5 is formed from a plurality of air bags 10, 11, so that the body is held by both air bags. However, according to this, when air is fed into both air bags 10 and 11 from an air supply mechanism (not shown), the body 5 is tilted, and one of the air bags 11 is strongly pressed by this tilt. , Air bag 10 to which no pressure is applied to the air
This has the disadvantage that a large amount of air is supplied to the sides and the air is not evenly supplied, resulting in a decrease in the holding power of the air bag 11.
本考案の目的は複数個に分割したエヤ袋に、仮
に身体からの圧力が加わつていても平等に空気が
送り込まれるようにして上記欠点を除去するもの
であり、以下実施例を用いて詳細に説明する。 The purpose of the present invention is to eliminate the above-mentioned drawbacks by allowing air to be fed equally even if pressure from the body is applied to the air bag divided into multiple parts. Explain.

Components that are the same as in FIG. 2 are designated by the same reference numerals. In the figure, 10 and 11 are air bags located on the left and right sides of the seat, and these air bags have hoses 12 and 13.
Pumps 14, 15 for supplying air via
The pumps 14 and 15 are arranged on a substrate 16 and are pressed by a pressing plate 17 that can move up and down against the substrate 16. The pressing plate 17 is guided by a guide member 18 so as to move only in the vertical direction, and the pressing plate 17 is moved by a pressing mechanism (not shown).
When a pressing force is applied to the substrate 16, the pressing plate 17 is kept in a horizontal state and is pressed in the direction of the substrate 16, and the pump 14,
15 will be compressed to the same amount. Due to this compression, the air bags 10 and 1 are
Air is pumped into the first side. In addition, air bag 10.1
Hoses 19 and 20 extend from 1, and both hoses 1
An air exhaust mechanism 21 is connected to the common part of the air bags 10, 20, and by operating this air exhaust mechanism 21, the air inside the air bags 10, 11 can be extracted. The amount of air inside 11 can be adjusted. In addition, the above hose 1
Check valves 22 and 23 are connected to 2 and 13 and 19 and 20 to prevent backflow of air.

題を解消することができる。 Therefore, according to the above configuration, the pressing plate 17
Pump 1 by applying vertical pressure to
4 and 15 are repeatedly compressed and expanded, and the air flows into hose 1.
It is fed into the air bags 10 and 11 via air bags 2 and 13. In this case, even if compressive force is applied to the air bag 11 by applying pressure from the body in advance to the air bag 11, the pumps 14 and 15 repeat compression and expansion by the same amount, so the air bags 10 and 11 are An equal amount of air will be pumped in. Therefore, even if compressive force is applied to the air bag 11 side, the same amount of air bag 1
0,11 can be inflated, it is possible to maintain the surface shape or surface hardness of the sheet uniformly, which solves the problem of conventional methods where only a part of the sheet swells abnormally or becomes abnormally hard. can be resolved.

等しくするとが可能となる。 In addition, in the present invention, an independent pump is provided for each of the two air bags, and the pump is pressed by the same pressing member to send air, but the present invention is not limited to this. As shown in Fig. 4, a plurality of air bags 3 are built into the seat cushion part 1 side and the seat back part 30 side.
Regarding air bags 1 and 32, these air bags 31 and 32 are also divided into left and right sides, and each of these divided air bags is connected to two pumps P 1 and P 2 that handle the left and right air bags, and both pumps P 1 , Air may be pumped into the left and right air bladders by P 2 . In this way, it becomes possible to equalize the amount of air supplied to the left and right air bags in the air bags 31 and 32.

て好ましい効果を発揮する。 As explained above, according to the seat with a built-in air bag according to the present invention, a plurality of air bags built into the seat are divided, a pump for supplying air is connected to each of the divided air bags, and a pump is connected to the air bag. By applying the same pressing force, it is possible to send the same amount of air into the air bags that are divided into multiple parts, and even when the body is tilted and the compressive force of the body is applied to some of the air bags. Since air can be fed uniformly even when the air is injected, the surface shape or surface hardness of the sheet can always be set to a uniform state, and this is a desirable effect when applied to a vehicle seat, for example.
