Abstract
Abstract A reclining chair adapted to be positioned in close adjacency to a room wall when in the upright sitting position and yet so structured as to allow ready assumption of any of a variety of reclined positions of occupancy without physical contact of any element thereof with the same room wall, the chair concept envisioning a fixed platform, a chassis movable linearly relative to the platform, and a body-supporting unit movable between the sitting and reclining positions relative to the chassis with a concomitant movement of a leg supporting unit between the retracted and extended positions respectively, a propeller link or other means connecting between the body-supporting unit and platform for propelling the body-supporting unit relative to the platform, with the chassis moving forwardly and progressively away from the wall as transition is made from upright sitting position to progressive positions of reclination, wherefore the body supporting unit is concomitantly moved forwardly away from the room wall, and with the chassis moving rearwardly and progressively toward the wall as transition is made from positions of reclination to upright sitting position, wherefore the body-supporting unit is concomitantly moved rearwardly and toward the room wall.

Claim 1
Independent Claim
188 words
A reclining chair adapted to be positioned in close adjacency to and forwardly of a room wall when in the upright sitting position and yet so structured as to allow ready assumption of a reclined position without physical contact with the same room wall, the reclining chair comprising, a base a chassis, a bodysupporting unit and a leg-supporting unit, means mounting the body-supporting unit on the chassis for movement between upright and reclining positions, means mounting the chassis on the base for linear movements relative to the base as the body-supporting unit is moved, means mounting the leg-supporting unit on the body-supporting unit for movements between retracted and extended positions concomitant with movements of the body-supporting unit, and means operatively-connecting the body-supporting unit and base for moving the chassis forwardly and progressively away from the wall and the body-supporting unit relative to the wall as transition is made from upright sitting position to position of reclination, and for moving the chassis rearwardly and progressively toward the wall and the body supporting unit relative to the wall as transition is made from position of reclination to upright sitting position.
