Abstract
The present invention provides a chair tilting control assembly which comprises a fixed frame mounted on a chair leg post, a tiltable member supported by the fixed frame to tilt downward about a lateral support shaft, and a chair seat movable downward under the weight of a sitter. The tilting control assembly comprises at least one tilting control spring for elastically supporting the tiltable member at a certain support position relative thereto, and a motion converting mechanism which converts downward movement of the seat into displacement of the support position rearwardly away from the lateral support shaft.
