Rocker-recliner chair

A rocker recliner chair comprising a base, a rocker cam assembly mounted on the base for rocking movement relative thereto, a seat, linkage means mounting a seat relative to the rocker cam assembly, said linkage means including a seat link extending generally in a forward-rearward direction of the chair while being fixed to the seat and being mounted for rotation relative to the rocker cam assembly about an axis located at a front portion of the chair and which is fixed relative to the seat link and the rocker cam assembly, a backrest, backrest linkage mounting the backrest relative to the seat, linkage means mounting a portion of the backrest linkage relative to the rocker cam assembly at a rear portion of the seat thereby mounting the rear portion of the seat relative to the rocker cam assembly, footrest linkage means mounting the footrest to the seat for movement between a retracted position extending below the front of the seat and an extended position projected forwardly from the front of the seat, means for driving the footrest between said retracted and extended positions thereof, a rock-blocking means preventing forward-rearward rocking movement of the rocking cam assembly relative to the base when the footrest is in said extended position, and linkage means interconnecting the rock-blocking means and said linkage which mounts part of said backrest linkage to the rocker cam assembly whereby said rock-blocking means is actuated to prevent forward-rearward rocking movement of the rocker cam assembly relative to the base when the footrest is extended.

A linkage system for a rocker-recliner chair of the type including a base, a rocker cam assembly mounted on the base, a seat mounted on the rocker cam assembly for movement with the rocker cam assembly during forward-rearward rocking movement relative to the base and also being movable relative to the rocker cam assembly placing the seat into reclining positions, a backrest mounted relative to the seat and the rocker cam assembly for movement with the seat and also for movement relative to the seat, 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 front of the seat;

• the linkage system comprising a seat link adapted to be fixed to an associated seat to extend generally in the forward-rearward direction of the associated chair, a cam link adapted to be mounted to an associated rocking cam, a seat link being mounted at a front end portion thereof relative to the cam link for rotation about an axis which is fixed relative to the seat and cam links, a backrest linkage adapted to mount the associated backrest relative to the seat link, the backrest linkage including a backrest link pivotally mounted to the seat link, and linkage mounting the backrest link relative to the cam link, a footrest linkage adapted to mount the associated footrest to the seat, the footrest linkage including a footrest mounting link pivotally mounted to the seat link, a draw bar link interconnecting the footrest mounting link and the linkage which mounts the backrest mounting link to the cam link, a rock-blocking linkage including a keeper link pivotally mounted to the cam link and having a slot therein, a constraining link pivotally connected to one end portion of said keeper link and adapted to be pivotally mounted to the associated base, a pin link having one end portion including a pin adapted to be received in said slot of said keeper link when the footrest linkage is extended, said pin link having an opposite end portion pivotally connected to said draw bar to be movable thereby, and an actuating and control link for the keeper link, said actuating and control link being pivoted at one end portion thereof to said pin link and being pivoted to an opposite end portion thereof to said keeper link.
