Abstract
A hinged glider mechanism includes a hinge device for pivoted mounting in a chair between a stationary base frame and a seat frame, for supporting the seat frame for oscillatory gliding motion generally longitudinally relative to the base frame. The hinge device is configured for repeated substantially silent pivotal oscillating cycles over an extended life. The hinge device includes a hinge panel consisting essentially of a polymeric material, such as acetal copolymer, that is characterized by a sufficient strength and durability to support the seat frame and a seat occupant during repeated and extended pivotal oscillating cycles without failure and a sufficient lubricity not to generate noise during the repeated and extended pivotal oscillating cycles.
