用ガススプリングの操作装置。 A backrest support disposed at the rear of a support frame supported by the legs of a chair and a rear end of a gas spring for adjusting the forward and backward tilting angle of the backrest support are rotatably connected, A bracket attached to the front end of the gas spring is pivotally supported by a pin on the front part of the support frame, and the bracket is rotatably provided with a pressing body that comes into contact with the push rod of the control valve in the gas spring. The middle part of the link, which is rotatably connected to the operating rod for pushing and pulling in the lateral direction from the outside, is rotatably supported on the support frame, and the point of contact between the tip of the link and the pressing body is the point at which the link rotates. The link is configured so that it moves beyond the dead center as it moves, and when the operating rod is pulled out, the tip of the link presses the pressing body and holds the pressing body in a state close to the push rod. Features a gas spring operating device for chair tilting.
