Abstract
A chair having a backrest with a Y-shaped member. The member being affixed to the center of the top rail of the backrest frame at one end. The other end of the Y-shaped member connects to backrest fabric, pulls it rearward, and holds the backrest fabric in tension using a pair of retractors. The backrest fabric is secured to the retractors by a welt cord contained within a chamber formed in each retractor. The welt cord is sewn into a fabric sheath that is, in turn, stitched to the backrest fabric. The member is biased to flex rearward when the backrest fabric moves rearward from an at-rest position.
