In a three-way wall-avoiding recliner chair including a base, a seat mounted relative to the base for movement between a normal position and a plurality of reclining positions located forwardly along the base from the normal position of the seat, a backrest mounted relative to the seat for movement with the seat relative to the base between a normal generally upright position when the seat is in its normal position and a plurality of reclining positions located forwardly along the base from the normal position, said backrest also being pivotable relative to the seat for placing the chair into advanced reclining positions, armrests mounted to the seat for movement relative to the seat between a normal position when the seat is in its normal position, and an advanced position forwardly of its normal position, and a footrest mechanism mounted to the seat for movement between a retracted position adjacent the seat when the seat is in its normal position and an extended position projected forwardly from the seat when the seat is in a reclined position; an improved linkage system comprising a carrier link (42), a seat link (40) fixed relative to the seat, a pair of front and rear spaced seat mounting links (43, 44) each pivotally connected to the carrier link (42) and the seat link (40) for mounting the seat link and in turn the seat relative to the carrier link with the seat link suspended from the carrier link, a front carrier mounting link (50) pivotally connected to the base (10) and pivotally connected to a forward portion of the carrier link, a rear carrier mounting link (52) pivotally connected at a lower end portion thereof to the base, an armrest link (60) fixed relative to an armrest, a rear armrest link (59) pivotally connected to the armrest link (60) and pivotally connected to an upper portion of the rear carrier mounting link (52), a drive transmission link (65) interconnecting the front armrest mounting link (64) and the front carrier mounting link (50) to drive the front carrier mounting link when the armrest is moved from its normal position forwardly relative to the base, sequencing linkage means (59a, 68, 79, 70) connected to the rear seat mounting link (44) and the rear armrest mounting link (59) for preventing relative movement between the carrier link (42) and the seat link (40) when the footrest is moved from retracted position to extended position but thereafter permitting movement of the seat link relative to the carrier link for placing the seat into advanced reclining positions, a backrest linkage including a backrest link (100) fixed relative to the backrest and pivotally connected to a rear portion of the seat link (40), an other backrest link (103) pivotally connected to the first backrest link (100) and pivotally connected to the rear seat mounting link (44) for swinging the seat mounting links and in turn the seat link and the seat relative to the carrier link for placing the seat in advanced reclining positions after the footrest has been moved to extended position, said sequencing linkage means preventing pivoting movement of said other backrest link (103) and in turn the backrest relative to the seat until the footrest has been moved to extended position, a footrest linkage pivotally connected to the seat for moving the footrest between retracted and extended positions, a footrest actuating link (90) pivotally interconnected between the front carrier mounting link (50a) and the footrest linkage to drive the footrest linkage forwardly from the seat when the armrest is moved forwardly from its normal position relative to the base.
Claim 3
Dependent Claim
49 words
The improved linkage system defined in claim 1 wherein said sequencing linkage means includes a sequencing link (70) pivotally connected to the rear seat mounting link (44) and having a slot (69), and a portion of said rear armrest mounting link (59a) having a pin received in said slot.
Claim 4
Dependent Claim
