Abstract:
1. A control assembly for a chair, comprising: a base structure including a stationary first pivot point and a stationary second pivot point spaced from the stationary first pivot point, wherein the base structure is adapted to be attached to a ground-abutting base support structure; a seat support structure directly pivotably coupled to the base structure for rotation about the stationary first pivot point, wherein the seat support structure is adapted to support a seated user thereon; a back support structure directly pivotably coupled to the base structure for rotation about the stationary second pivot point, wherein the back support structure is adapted to move between a first position and a second position; a control link having a first end operably coupled to the seat support structure, and a second end operably coupled to the back support structure; and at least one biasing assembly exerting a biasing torque about the stationary second pivot point and exerting a biasing force on the back support structure that biases the back support structure from the second position towards the first position, wherein the biasing torque is adjustable between first and second magnitudes when the back support structure is in the first position, and wherein the second magnitude is greater than the first magnitude.
