Adjustable seating comprises a frame having a seat-supporting portion and a back-supporting portion, a seat bottom mounted on the seat-supporting portion for movement between rearward and forward positions and a seat back mounted on the back-supporting portion by at least one resilient articulating linkage for tilting movement independently of the position of the seat bottom. The seat back is connected to the seat bottom by a flexible but non-extensible coupling member and is slidable up and down on an upper linkage member of the articulating mechanism so that when the seat bottom moves forwardly or backwardly, the seat back moves downwardly or upwardly, respectively, in correspondence with the movements of the seat bottom. A configuration control spring biases the seat back/bottom to an upward/rearward configuration. |
