Abstract
A chair includes a base, a seat, a back, and a control operably supporting the seat and back on the base for movement between upright and recline positions. The seat and back include a stiff perimeter frame with opposing perimeter sections, and a plurality of rods each independently bendable in vertical and angled directions. End bearings on the rods are captured in pockets in the perimeter frame, which limits their inward and outward sliding movement. The control includes front and rear leaf springs and a pivot arm operably supporting the seat and the back for synchronous movement, with the direction of movement being such that energy is stored during recline. The energy stored during recline assists in providing a heavier person with added counterbalancing force during recline. A booster mechanism is also selectively engageable for added support upon recline.
