The member 3 is fixed, and one end of a gas cylinder 4 installed in the support frame 2 is rotatably supported on the front part of the seat receiving member 3 and rocking is supported on the rear part of the bearing member 3. A support piece 8 is axially mounted on one end of the member 6,
The support piece 8 holds the tip end of the gas cylinder 4 and presses the pin 4'of the gas cylinder 4 to operate the gas cylinder.
The gist of the present invention is that the back support column 10 is attached to the inside of the locking member 6 and to the rear portion of the locking member 6.

ンダー４が作動するようになる。EXAMPLE Hereinafter, an example of the present invention will be described in detail with reference to the drawings. 1 is a pedestal, 2 is a support frame fixed on the pedestal, 3 is a seat support fixed on the support frame 2 by means such as welding. The members 4 are installed in the support frame 2, and one end of which is a gas cylinder rotatably supported by a shaft 5 at the front part of the seat receiving member 3,
Reference numeral 6 is a rocking member whose middle portion is rotatably supported by a shaft 7 at the rear portion of the seat receiving member 3, and a supporting piece 8 is axially mounted on a tip end of the supporting piece 8 by the shaft 9. The gas cylinder 4 is fixedly held on 8, and the rear portion of the locking member 6 is exposed rearward from the seat receiving member 3, and the back support column 10 is attached to this exposed portion. Reference numeral 11 denotes a pin pressing metal fitting provided in the support piece 8, which is connected to a lever 12 provided on the side surface of the chair by a wire cable. By operating the lever 12, the pin pressing metal fitting 11 is connected to the pin 4 of the gas cylinder 4. 'And the gas cylinder 4 is activated.
考案の作用、効果 本案はガスシリンダー４が伸長した状態の時は背当は前
方に位置し、縮んだ状態の時は後方に位置するようにな
る。Action and effect of the invention In the present invention, the backrest is located in the front when the gas cylinder 4 is in the extended state, and is located in the rear when the gas cylinder 4 is in the contracted state.
而してレバー12の操作によつてピン押金具11がガスシリ
ンダー４のピン４′を押すとガスシリンダー４が伸長
し、これによつて軸９が下降し、ロッキング部材６が軸
７を支点として回動し、背当は前傾状態となる。When the pin pressing member 11 pushes the pin 4'of the gas cylinder 4 by operating the lever 12, the gas cylinder 4 extends, whereby the shaft 9 descends and the locking member 6 fulcrums the shaft 7 as a fulcrum. As a result, the backrest is tilted forward.
又この前傾状態において背当に体重をかけた状態でレバ
ー12を操作してピン４′に対するピン押金具11の押圧を
解除すればガスシリンダー４が縮む方向に作動して該ガ
スシリンダー４の索引によりロッキング部材６が軸７を
支点として上方回動して背当が後傾状態となるものであ
る。Further, in this forward leaning state, when the lever 12 is operated with the weight on the backrest to release the pressing force of the pin pressing member 11 against the pin 4 ', the gas cylinder 4 operates in a contracting direction and the gas cylinder 4 moves. The indexing causes the locking member 6 to pivot upward about the shaft 7 as a fulcrum and the backrest to be tilted backward.
本案は以上のようにガスシリンダー４の動きによつて無
段階的に任意の角度に背当の角度を円滑に調整し得る非
常に有益な背当の角度調節装置を提供し得るものであ
る。As described above, the present invention can provide a very useful backrest angle adjusting device that can smoothly adjust the backrest angle to any angle by the movement of the gas cylinder 4.
