ABSTRACT:
A three-way, handle-operated, rocker-recliner chair includes a base, a rocker frame mounted on the base, a carrier link pivotally mounted on the rocker frame, a seat and armrest unit pivotally mounted on the carrier link through a linkage which includes a backrest link fixed to the backrest, a footrest linkage mounted to the seat and armrest unit and actuated by a manual control handle. When moving from upright to TV position where the footrest is extended, a sequencing linkage prevents relative movement between the seat and backrest and the carrier link during an initial phase of such movement but later permits the seat and backrest to be moved into various advanced reclining positions when the occupant exerts pressure on the backrest which fulcrums about the carrier link. Because of chair styling and leverage requirements, the seat has a seat link with an upwardly projecting V-shaped rear portion which is pivotally connected to the backrest link. A support link is pivotally interconnected between the carrier link and the seat link at the V-shaped portion to help resist stress imparted to the V-shaped portion when the occupant moves into advance reclining positions. A positive lock mechanism is provided to prevent rocking movement of the rocking frame when the seat moves into the TV position.
