Abstract

A lowback reclining chair with a concealed headrest positionable in close adjacency to a room wall when in 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 envisioning a combination of kinematically related components comprising a base, a chassis movable relative to the base, and a body-support movable between sitting and reclining positions relative to the chassis with concurrent movements of a legrest and a headrest each between retracted and extended positions respectively, a main drive link connecting between the body-support and base for propelling the chassis relative to the base forwardly and progressively away from the wall as the body-support is moved from upright sitting position to progressive positions of reclination while the body support is concurrently moved rearwardly relative to the chassis but yet away from the room wall, and for propelling the chassis relative to the base rearwardly and progressively toward the wall as the body-support is moved from progressive positions of reclination to upright sitting position while the body support is concurrently moved forwardly relative to the chassis but yet toward the room wall.

Claims

1. A reclining chair characterized by being positionable in close adjacency to and free of attachment to a room wall or article of furniture when disposed in upright sitting mode and to be shiftable into any reclining mode free of any physical contact with that room wall or article of furniture the reclining chair kinematically constituting a single mechanism consisting of:

a base, a chassis supported relative to the base,

a body-support including a seat and a back separable from the seat,

a headrest, a legrest, means for mounting the body-support relative to the chassis for movements between upright sitting and reclining modes,

means for mounting the chassis relative to the base in a linear movement relative to the base as the body-support is concurrently moved,

means for mounting the headrest and legrest relative to the body-support for movement between retracted and extended positions as the body-support is concurrently moved,

and means operatively-connecting the body-support and base for moving the chassis forwardly and progressively away from the wall and the body-support relative to the chassis and the wall as transition is made from upright sitting position toward a reclining position and for moving the chassis rearwardly and progressively toward the wall and the body-support relative to the chassis and the wall as transition is made from a reclining position toward upright sitting position.

2. An occupant-operated living room type reclining chair positionable anywhere on a floor of a room free of attachment to the floor and in close adjacency to and forwardly of an object when in upright sitting position and yet so constructed as to allow ready assumption of any reclined position free of physical contact with the same object and comprising:

a base resting on the floor, free of permanent attachment to the floor, a chassis supported relative to the base, a body-supporting subassembly including a seat and backrest, a leg-supporting subassembly, a headrest subassembly, and linkage means operatively-interconnecting the body-supporting subassembly and leg-supporting subassembly and headrest and chassis and base for, first, concurrently moving;

a. the body-supporting subassembly rearwardly relative to the chassis,

b. the leg-supporting subassembly and headrest subassembly between retracted and extended positions, and

c. the chassis relative to the base and progressively forwardly away from the object,

as transition is made from upright sitting position to a position of reclination by the occupant leaning backwardly against the backrest and exerting a forwardly-pushing force against the chassis, and for, second, concurrently moving;

a. the body-supporting subassembly forwardly relative to the chassis,

b. the leg-supporting subassembly and headrest subassembly between extended and retracted positions, and

c. the chassis relative to the base and progressively rearwardly toward the object, as transition is made from a position of reclination to upright sitting position by the occupant leaning forwardly away from the backrest and exerting a downwardly-pushing force against the leg-supporting subassembly, with any linear movement of the body-supporting subassembly relative to the base being in substantially inverse ratio to any linear movement of the chassis relative to the base.

3. A reclining chair movable by the occupant between upright sitting and intermediate-television and fully-reclined positions and positionable anywhere on a floor of a room and free of attachment to the floor and in close adjacency to a wall when in upright sitting position and yet so structured as to allow ready assumption of intermediate-television and fully-reclined positions free of contact with the wall comprising:

a base, a chassis, a body-supporting subassembly including a seat and backrest, a leg-supporting subassembly, a headrest subassembly, linkage means for effecting movement of the body-supporting subassembly between upright and intermediate and reclined positions concurrently with movement of the leg-supporting subassembly and headrest sub-assembly between retracted and extended positions respectively and for effecting movement of both the chassis and body-supporting subassembly relative to the base in one direction responsively to and simultaneously with movement of the body-supporting subassembly relative to the chassis in counter direction.

4. A reclining chair adapted to be movable on a floor of a room and into close adjacency to and forwardly of an object when in upright sitting position and yet so structured as to allow ready assumption of a reclining position free of physical contact with the same object, the reclining chair comprising:

a base, a chassis supported relative to the base, a body-support including a seat and back and legrest and headrest having pivotal relationships as to each other, control means for controlling the pivotal movements of the back relative to the seat of the body-support, and linkage means operatively-interconnecting the body-support and chassis and base and legrest and headrest for concurrently moving the chassis relative to the base and forwardly and progressively away from the object and the body-support rearwardly relative to the chassis and the legrest and headrest from retracted to an extended position as transition is made from upright sitting to reclination positions and for concurrently moving the chassis relative to the base rearwardly and progressively toward the object and the body-support forwardly relative to the chassis and the legrest and headrest from an extended to retracted position as transition is made from reclination to upright sitting positions.

5. A reclining chair adapted to be positioned on a floor more particularly in close adjacency to and forwardly of an object when in upright sitting position and yet so structured as to allow ready assumption of a reclining position without physical contact with the same object, the reclining chair comprising:

a base, a chassis supported relative to the base,

a seat and a back having a pivotal relationship as to each other, a legrest, a headrest, roller means disposed between and fixed to one of the chassis and base, control means for controlling the pivotal movements of the back relative to the seat, and linkage means operatively-interconnecting the seat and back and legrest and headrest and chassis and base for concurrently propelling the chassis relative to the base and forwardly and progressively away from the object and the seat rearwardly relative to the chassis and the legrest and headrest from retracted to an extended position as transition is made from upright sitting position to a position of reclination responsively to an impelling force generated by the occupant upon the chassis in one direction with a resultant reaction of the seat relative to the chassis in a counter direction.
