Abstract
A mechanism for use in motion furniture that reduces the complexity and links of typical linkage mechanisms. The mechanism has a base plate and a footrest mechanism. The mechanism also includes a seat support link coupled to the footrest mechanism and front and rear pivot links rotatably coupled to the seat support link and slidably and rotatably coupled to the base plate. An ottoman drive link is slidably and rotatably coupled to an intermediate portion of the front pivot link and rotatably coupled to an intermediate portion rear pivot link. A primary ottoman link couples the ottoman drive link and the footrest mechanism. The primary ottoman link is rotatably coupled to the seat support link at an intermediate portion, so that the primary ottoman link and the ottoman drive link cooperate to move footrest mechanism between a closed chair position and an open recliner position. A backrest linkage couples the seat support link to the base plate, so that the backrest linkage cooperates to move the recliner mechanism between the open recliner position and the fully-reclined position.
