Abstract
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.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
375 words
A three-way rocker-recliner chair having a base, a rocker frame (6) mounted on the base for rocking movement in the forward-rearward direction of the chair, a carrier link (4), front and rear carrier mounting links (7, 5A) mounting the carrier link to the rocker frame for movement generally forwardly and rearwardly of the rocker frame, a seat including a seat link (5), armrests fixed to the seat for movement with the seat as a unitary structure, a seat mounting link (3) pivotally interconnected and mounting the seat link to the carrier link, a backrest including a backrest link (1) pivotally mounted to the carrier link and pivotally connected to the seat link for movement relative thereto, said backrest link (1) and seat mounting link (3) serving to mount the seat link relative to the carrier link, a seat support link (2) pivotally connected to the seat link and the carrier link to provide support for the seat link when the chair is in advanced reclining positions wherein the backrest has moved relative to the seat, a footrest including a footrest linkage mounting the footrest to the seat for movement between extended and retracted positions, a manual control handle connected to the footrest linkage to actuate the same between extended and retracted positions, a transmission link (8) interconnecting the footrest linkage and one of the carrier mounting links (5A, 7) for driving the carrier link forwardly relative to the rocker frame when the footrest is moved to extended positions, and sequencing linkage (12, 12A, 12B) preventing relative movement between the backrest link (1) and seat link (5) and the carrier link (4) during an initial phase of movement of the footrest from retracted to extended position and subsequently allowing such relative movement to phace the chair in advanced reclining positions when pressure is exerted on the backrest by the occupant of the chair, and wherein the seat link (5) has a generally V-shape including a bight portion and extends upwardly at its rear end and wherein said seat support link (2) is connected to said seat link in the area of said bight portion, and wherein when moving to advance reclining positions the backrest link (1) fulcrums about a rear end portion of the carrier link.
Claim 2
Dependent Claim
375 words
A three-way rocker-recliner chair having a base, a rocker frame (6) mounted on the base for rocking movement in the forward-rearward direction of the chair, a carrier link (4), front and rear carrier mounting links (7, 5A) mounting the carrier link to the rocker frame for movement generally forwardly and rearwardly of the rocker frame, a seat including a seat link (5), armrests fixed to the seat for movement with the seat as a unitary structure, a seat mounting link (3) pivotally interconnected and mounting the seat link to the carrier link, a backrest including a backrest link (1) pivotally mounted to the carrier link and pivotally connected to the seat link for movement relative thereto, said backrest link (1) and seat mounting link (3) serving to mount the seat link relative to the carrier link, a seat support link (2) pivotally connected to the seat link and the carrier link to provide support for the seat link when the chair is in advanced reclining positions wherein the backrest has moved relative to the seat, a footrest including a footrest linkage mounting the footrest to the seat for movement between extended and retracted positions, a manual control handle connected to the footrest linkage to actuate the same between extended and retracted positions, a transmission link (8) interconnecting the footrest linkage and one of the carrier mounting links (5A, 7) for driving the carrier link forwardly relative to the rocker frame when the footrest is moved to extended positions, and sequencing linkage (12, 12A, 12B) preventing relative movement between the backrest link (1) and seat link (5) and the carrier link (4) during an initial phase of movement of the footrest from retracted to extended position and subsequently allowing such relative movement to phace the chair in advanced reclining positions when pressure is exerted on the backrest by the occupant of the chair, and wherein the seat link (5) has a generally V-shape including a bight portion and extends upwardly at its rear end and wherein said seat support link (2) is connected to said seat link in the area of said bight portion, and wherein when moving to advance reclining positions the backrest link (1) fulcrums about a rear end portion of the carrier link.
Claim 3
Dependent Claim
140 words
The chair defined in claim 1 wherein there is further included a locking member extending below the seat in the forward-rearward direction of the chair, a keeper fixed to the base at a front portion thereof and adopted to receive the locking member to prevent rocking movement of the rocker frame, the locking member having a rear end portion pivotally connected to the rear carrier link (5A) to be actuated thereby in the forward direction of the chair and into the keeper when the footrest is moved to extended position to thereby prevent rocking of the chair, said locking member being removable from the keeper by said rear carrier mounting link (5A) to permit rocking movement of the chair when the footrest is moved to retracted position causing the carrier link to move in the rearward direction of the chair.
