Abstract
A chair height control mechanism has a gas cylinder with a valve control finger extending from an upper end overlain by a tilting actuator. A resilient pad is adhered to the upper end of the gas cylinder surrounding the valve control finger and maintains a spacing between the valve control finger and actuator when the actuator is not in use to avoid rattle.
Claims8
A chair control mechanism, comprising:
- a gas cylinder with a valve control finger extending from one end;
- a gas cylinder actuator disposed over said valve control finger;
- an annular disk fabricated of a resilient material mounted on said one end of said cylinder surrounding said valve control finger and perpetually deformed into a compressed state by said gas cylinder actuator so that said disk perpetually urges said actuator away from said valve control finger.
Dependencies are inferred from the claim text.
