Abstract
A tilt control mechanism that is mounted to the underside of a chair bottom, and permits the user or sitter to selectively control the chair height, as well as the degree of chair tilt. A tension adjustment mechanism is provided to permit the user to change the amount of spring tension exerted against the chair bottom when the chair is tilted back. Finally, a structural support is provided which interconnects the seat bottom with the tilt mechanism, and transmits downwardly-exerted weight to the mechanism. Each of these four mechanisms comprises a number of parts seated within a die cast enclosure or housing.
