Abstract
Abstract A chair having a seat and a back support pivoted to the seat on a fixed hinge axis adjacent the rear edge of the seat. A chair back is slidable along the back support toward and from the hinge axis. A link is pivoted at one end to the seat at a point forwardly of and above the hinge axis and is pivoted at its other end to the slidable chair back above the hinge axis so that rearward tilting of the back support and seat back causes the seat back to slide toward the hinge axis.
