Abstract
A chair adjustment mechanism for adjusting a position of a chair component. The mechanism comprises a first adjustment shaft, a second support shaft, as well as a set of friction plates, each friction plate comprising an elongated slot and the friction plates being fixedly mounted on the second support shaft while being slideably mounted on the first adjustment shaft. A guiding structure directs movement of the second support shaft along a direction of travel of the chair component. An adjustment handle is provided to reversibly compress the friction plates together in a locked position for fixing position of the component of the chair through braking displacement of the second support shaft along the guiding structure. The plurality of friction plates provides greater braking pressure for locking the mechanism.
