In the figure, 3b shows the airbag at the time of reduction.
As shown in the drawing, the inflated airbag 3a is reduced like an airbag 3b which is reduced when exhausted by an exhaust opening / closing solenoid valve (described later), and the cover 19 is recessed backward.
At this time, since the airbag 3a is bonded to the cover 19 by the upper bonding portion 20 and to the back plate 16 of the support bag by the bottom bonding portion 20 as described above, the cover 19 follows the recess of the airbag 3. .

図4及び図5に示したように、エアバック3は各々を操作によって膨張または縮小できるので、その組み合わせによって所要の凹凸を生成することができる。
例えば、上部の左右2ケを膨張させ、他を縮小させれば前記幼児のバックレストにすることができ、あるいは各個所を特殊体型の患者の背部に合わせて調節することによりフィットさせることができる。
As shown in FIGS. 4 and 5, each airbag 3 can be inflated or contracted by operation, so that necessary unevenness can be generated by the combination thereof.
For example, if the upper left and right two are inflated and the others are reduced, they can be used as the backrest of the infant, or can be fitted by adjusting each part according to the back of a special patient. .

FIG. 8 is a block diagram of a dental treatment chair with the support bag attached thereto.
In the figure, 34, 37, 40, 43, 46, 49 are open / close solenoid valves for air introduction adjustment, 36, 39, 42, 45, 48, 51 are exhaust open / close solenoid valves, 35, 38, 41, 44, 47 and 50 are check valves, 52 is an open / close solenoid valve for an air main line, 53 is an overpressure air discharger, and 54 is a power line.

サポートバック2内に配設された6ケのエアバック3には、エアチューブ7経由エア出入口7’からエアが出し入れされ膨張または縮小する。
上記エアの操作制御は、次のようにして行われる。
まず、幹線エアチューブ5を操作ボックス6の操作スイッチであるエア幹線用ON、OFFスイッチ32によりエア幹線用の開閉電磁弁52を開きエアを導入する。
次ぎに所要のエアバック3に対応する操作スイッチの2極型ON、OFFスイッチを操作する。
The six airbags 3 disposed in the support bag 2 are inflated or reduced by air being taken in and out from the air inlet / outlet 7 ′ via the air tube 7.
The air operation control is performed as follows.
First, the air main line open / close solenoid valve 52 is opened by the main air tube 5 by the air main line ON / OFF switch 32 which is an operation switch of the operation box 6 to introduce air.
Next, the bipolar switch ON / OFF switch of the operation switch corresponding to the required airbag 3 is operated.

例えば、左上方のエアバックであれば、2極型ON、OFFスイッチ26の1極をONにし、エア導入調整用の開閉電磁弁40を開くと、逆止弁41を経由し、エアが導入され前記エアバックが膨張する。
限度を超えると、各エアバック3に配設されている例えばバネと弁からなる過剰圧エア排出器53がリミッターとして作動する。
従って、エアの導入の調節は前記2極型ON、OFFスイッチ26の作動時間に比例する。
また、エアを抜きたい時は、同様に前記2極型ON、OFFスイッチの他の1極をONにし、排気用開閉電磁弁42を開いて外部に排気して調整する。
なお、2極型ON、OFFスイッチの中点はOFFで、ボタンから指を放すと自動復帰する。
For example, in the case of an air bag on the upper left, when one pole of the two-pole type ON / OFF switch 26 is turned on and the open / close solenoid valve 40 for air introduction adjustment is opened, air is introduced via the check valve 41. The airbag is inflated.
When the limit is exceeded, the overpressure air discharger 53 composed of, for example, a spring and a valve disposed in each airbag 3 operates as a limiter.
Therefore, the adjustment of air introduction is proportional to the operation time of the bipolar type ON / OFF switch 26.
Further, when it is desired to release air, similarly, the other one pole of the two-pole ON / OFF switch is turned ON, and the exhaust opening / closing solenoid valve 42 is opened and exhausted to the outside.
The middle point of the two-pole type ON / OFF switch is OFF, and automatically returns when the finger is released from the button.

上記は1ケのエアバック3の系統の作動について述べたが、他のエアバック3も同様にして、任意に膨張または縮小することができる。
幹線エアチューブ5からのエアの供給を停止する時には、幹線用ON、OFFスイッチ33を押してOFFにし前記開閉電磁弁52を閉にする。
なお、幹線用ON、OFFスイッチ32、33は直列とし、32をON用、33をOFF用とすれば操作が簡単である。
Although the above has described the operation of the system of one airbag 3, other airbags 3 can be expanded or contracted arbitrarily in the same manner.
When the supply of air from the main line air tube 5 is stopped, the main line ON / OFF switch 33 is pressed to turn it OFF to close the open / close solenoid valve 52.
It should be noted that the operation is simple if the main line ON / OFF switches 32 and 33 are connected in series, with 32 for ON and 33 for OFF.

また、本器のサポートバック内のエアバックを調節する動力源のエアは、歯科用治療椅子においてはエアタービン、スリーウェイシリンジ等のハンドピースに使用されるエアが常設されているため、分岐して容易にエアバックに接続することができる。   Also, the power source air that adjusts the air bag in the support bag of this device is branched because the air used for handpieces such as air turbines and three-way syringes is permanently installed in dental treatment chairs. And can be easily connected to the airbag.
