Abstract

A rocker-recliner chair utilizing but two mounting links for mounting the seat and backrest to the rocker cams and which mounting links are also utilized to position the chair in advanced reclining positions beyond the TV position. The chair is biased to the TV position wherein the footrest is extended, by the weight of the chair occupant acting through the rear mounting link. However, the chair is retained in upright position against the gravity basis by a spring-loaded lock mechanism which is actuated by a handle to release the lock mechanism to allow the occupant's weight to drive the chair to TV position. When moving to TV position, the seat undergoes a certain amount of rearward displacement relative to the rocking cams to position the weight of the occupant to the rear while a "landing gear" stop descends to engage the base to thus prevent rearward rocking of the chair. In the preferred embodiment where the backrest is pivoted for movement relative to the seat to obtain advanced reclining positions, a sequencer link prevents movement of the backrest relative to the seat until the chair reaches TV position. This sequencer link also serves the important purpose of reinforcing the linkage system.

Dependent claims

In a three-way recliner chair including a base, and a seat and backrest assembly including a seat and backrest, a linkage system for mounting the seat relative to base and the backrest relative to the seat for movement between a generally upright position and a reclined position, the linkage system including a backrest link fixed to the backrest and pivotally connected to the seat, a front mounting link pivoted intermediate its ends to the seat at a first location while also being pivoted directly to the backrest link at a second location spaced from said first location, means pivotally interconnecting the front mounting link and the base at a third location spaced from said first location on one side of said first location opposite said second location while permitting translation of the front mounting link relative to the base, and a rear mounting link located rearwardly of the front mounting link and pivotally connected to the backrest link and the base.

In a three-way reclining chair including a base, and a seat and backrest, a linkage system for mounting the seat and backrest relative to the base for movement between a generally upright position and a reclined position, the linkage system including a footrest linkage connected to the seat and movable between extended and retracted positions, a backrest link fixed to the backrest and pivotally connected to the seat, a front mounting link pivotally connected to the seat at a first location intermediate the ends of the front mounting link while also being pivotally connected to the backrest link at a second location spaced from said first location, means pivotally interconnecting the front mounting link and the base at a third location spaced from said first location on one side of said first location opposite said second location while permitting translation of the front mounting link relative to the base, a rear mounting link pivotally connected to the backrest link and the base, and a drive link having a rear end pivotally connected to the rear mounting link to be driven thereby and having a front end pivotally connected to the footrest linkage to drive the same, and a sequencing link pivotally interconnecting said backrest and drive links to prevent movement of the backrest relative to the seat until the footrest linkage is moved towards extended position, said sequencing link also serving to reinforce the linkage system.

For use in a three-way reclining chair including a base, and a seat and backrest;

a linkage system for mounting the seat and backrest relative to the base for movement between a generally upright position and a reclined position, the linkage system including a seat link adapted to be connected to a seat, a footrest linkage connected to the seat link and movable between extended and retracted positions, a backrest link adapted to be fixed to the backrest and pivotally connected to the seat link, a front mounting link pivoted intermediate its ends to said seat link at a first location while being pivoted to the backrest link at a second location spaced from said first location, a base link adapted to be mounted to a base, means pivotally interconnecting the front mounting link and the base link at a third location spaced from said first location on one side of said first location opposite said second location while permitting translation of the front mounting link relative to the base link, a rear mounting link pivotally connected to the backrest link and pivotally connected to the base link, a drive link having a rear end pivotally connected to the rear mounting link to be driven thereby and having a front end pivotally connected to the footrest linkage to drive the same, and a sequencing link pivotally interconnecting said backrest and drive links to prevent movement of the backrest link relative to the seat link until the footrest linkage is moved towards extended position, said sequencing link also serving to reinforce the linkage system.
