A chair seat adjustment mechanism has a support, a back bracket for attachment to a chair back and a seat plate for attachment to a chair seat. The back bracket is pivotally mounted to the support at a first pivot. The seat plate, which extends above the support, is pivotally mounted to the back bracket at a second pivot and slidably hinged to the support at a third pivot. The second pivot is positioned above and rearwardly of the first pivot. The third pivot is positioned forwardly of the second pivot such that rearward titling of the back bracket draws the seat plate rearwardly and tilts a rear of the seat plate downwardly. The third pivot may be a pivot pin on the support slidably received in an elongate slot on the seat plate, which may be slightly declined towards the back. A chair having such a chair seat adjustment mechanism is more comfortable for some users. |
