ABSTRACT:
A reclining chair positionable in close adjacency to a room wall in an upright sitting position and allowing ready assumption of any of a variety of reclining positions without physical contact of any chair component with that room wall. The chair envisions a fixed base, a chassis movable linearly relative to the base, and a body-support movable between the sitting/retracted and reclining/extended positions relative to the chassis, a first system of links operatively connecting between the base and chassis and body-support for effecting linear movement of the chassis relative to the base, and a second system of links connecting between the first system of links and the base and chassis and body-support unit for effecting reclining movement of the body-supporting unit relative to the chassis, said base, chassis, body-support and systems of links constituting kinematically speaking, but a single mechanism. The movements of the link systems are so coordinated that the chassis moves progressively forwardly away from the room wall as transition is made from upright sitting position to progressive reclining positions to the end that the body supporting unit is concurrently moved forwardly away from the room wall. Reversely, with the chassis moving rearwardly and progressively toward the room wall as transition is made from progressive reclining positions to upright sitting position, the body-supporting unit is concurrently moved rearwardly and toward the room wall.
