Wall-avoiding recliner chair
First Claim
1. A reclining chair comprising in combination:
- a base, a seat, seat linkage means mounting the seat relative to the base for movement forwardly or rearwardly relative to the base as well as for movement into different reclining positions extending at an angle to the horizontal relative to the base, said linkage means including a carrier link, a seat link fixed to the seat, suspension linkage suspending the seat link from the carrier link for pivotal movement relative to the carrier link, and a mounting linkage pivotally mounting said carrier link relative to the base;
a backrest, backrest linkage means pivotally mounting the backrest relative to the seat for movement between a substantially upright position and a number of reclining positions;
a footrest, footrest linkage means mounting the footrest relative to the seat for movement between a retracted position adjacent the seat and an extended position projected forwardly from the seat, footrest actuating linkage means independent of the backrest for moving the footrest linkage means to position the footrest in said retracted or extended positions; and
an actuating and control linkage interconnecting the footrest actuating linkage means and the mounting linkage for moving the mounting linkage forwardly relative to the base when the footrest is moved to said extended position.

Abstract
A recliner chair with wall-avoiding action which permits the chair to be placed adjacent a wall without striking the wall when the chair is moved to reclining positions. The wall-avoiding action is achieved through a linkage which suspends the seat and its rigidly incorporated armrests, relative to a fixed base for swinging movement between a normal or generally upright position, and a number of reclining positions where the backrest extends rearwardly at an incline and the seat also extends at an incline. A handle-operated footrest is provided and an actuating and control link is connected between linkage which actuates the footrest and the linkage which mounts the seat to the base so as to move the latter forwardly relative to the base when the footrest is moved to extended position to provide a certain amount of wall-avoiding action. This actuating and control link prevents movement of the backrest relative to the seat when the chair is in normal position or is operated to extend the footrest. However, once the footrest is in extended to "TV" position, the backrest may be pivoted rearwardly relative to the seat to provide advanced reclining positions by the occupant exerting back pressure on the backrest. This also operates to swing the seat forwardly and upwardly relative to the base to provide further wall-avoiding action and also to position the seat in a comfortable reclining position. The chair is maintained in any of its positions by virtue of the balance of the linkage system, and no spring assists are needed to help to maintain position or move the chain into any new position.

22. A linkage mechanism for a recliner chair of the type including a base, a seat mounted on the base for movement relative to the base between upright and reclining positions, a backrest mounted to the seat for movement with the seat relative to the base and also for movement relative to the seat between upright and reclining positions, and a footrest mounted to the seat for movement between a retracted position at the front of the seat and an extended position projected forwardly from the chair;
- the linkage mechanism comprising in combination, a seat link adapted to be fixed to the seat of an associated chair, a carrier link positioned above the seat link, front and rear suspension links each pivotally connected to the carrier link at locations spaced along the carrier link and also pivotally connected to the seat link at locations spaced along the longitudinal direction of the seat link for suspending the seat link from the carrier link for pivotal movement relative thereto, front and rear mounting links each pivotally connected to the carrier link at locations spaced along the carrier link and adapted to be pivotally connected to the base of an associated chair for mounting the seat of the chair relative to the base through the carrier link, a backrest link adapted to be fixed to the backrest of an associated chair and being pivotally connected to a rear portion of the seat link, an actuator link pivotally connected to the backrest link and also pivotally connected to the rear suspension link for swinging the suspension links and the seat link relative to the carrier link upon actuation of the backrest link, a footrest actuating linkage adapted to be connected to the footrest of an associated chair for actuating the footrest between extended and retracted positions relative to the chair, and an actuating and control link pivotally connected to the rear mounting link and also pivotally connected to the footrest actuating linkage for driving the rear mounting link when the associated footrest is moved to extended position, said carrier link, suspension links and seat link forming a closed four-bar linkage adapted to be moved forwardly and rearwardly of the base of an associated chair by means of the mounting links.

30. A recliner chair comprising in combination:
- a base, a seat, a carrier link, a pair of front and rear suspension links pivotally connected at their lower portions to the seat at locations spaced longitudinally along the seat in the forward-rearward direction of the chair, said suspension links having upper portions pivotally connected to the carrier link at locations spaced longitudinally along the carrier link in the forward-rearward direction of the chair to pivotally suspend the seat from the carrier link, a pair of front and rear mounting links having upper portions pivotally connected to the carrier link at locations spaced longitudinally of the carrier link and having lower portions pivotally connected to the base at locations spaced longitudinally along the base in the forward-rearward direction of the chair, a backrest pivotally connected to the seat, said carrier link, suspension links and seat forming a first closed four-bar linkage, said carrier link, mounting links and base forming a second closed four-bar linkage, a first actuator link pivotally connected to the backrest and pivotally connected to the rear suspension link for driving the first four-bar link relative to the carrier link, a footrest, footrest actuating linkage connected to the footrest for moving the footrest, a retracted position adjacent the front of the chair and an extended position projected forwardly of the chair, and an actuating and control link connected to the footrest actuating linkage and pivotally connected to one of the mounting links for moving the second four-bar linkage forwardly relative to the base when the footrest is moved to extended position.
