How does an Adjustable piston stool/ Office chair Work?
Hi,
Can anyone Tell me or, even better, tell me a Link which shows how the piston on a office chair adjusts the Height? I need this for my Product Design School Course.
Thanks.
It is a Gas Cylinder that has an Internal piston that compresses a gas to a higher Pressure when Weight is put on it. A friction Clamp to Hold the piston's Rod in a Set position is the height selector. A Soft Spring gives a Bit of Cushion when a person sits on the chair. If the chair is too low, a Lever releases the friction clamp, letting the piston Come up, raising the chair against the chair's weight. If a person is sitting in the chair at that Time, the gas pressure against the piston is Not enough, and the chair goes Down.
