Abstract
This invention is related to a mechanism for use in a rocker recliner chair that reduces the complexity and links of typical linkage mechanisms. The rocker recliner chair includes a base, a rocker cam assembly mounted on the base, a seat, a footrest, a backrest and a pair of linkage mechanisms mounted on opposite sides of the chair. Each of the linkage mechanisms includes a recliner mechanism, a drive mechanism, and a footrest mechanism. The recliner mechanism is coupled to the base. The drive mechanism includes an ottoman drive bell crank and an ottoman drive link. The ottoman drive bell crank is coupled to a rear portion of the recliner mechanism. The ottoman drive link couples the ottoman drive bell crank to the footrest mechanism. The footrest mechanism is connected to the recliner mechanism by a footrest extension linkage. The footrest extension linkage serves to unlock the footrest mechanism thereby allowing the weight of the user, along with the drive mechanism, to move the chair from the chair position to the recliner position.
