Abstract
This invention is related to a recliner chair having a footrest mechanism and a recliner mechanism. The recliner chair includes a footrest, a seat, back, and a pair of spaced apart armrests. The recliner mechanism, in one aspect, broadly includes a base plate, a seat mount plate, a recline link, a seat lift link, a control linkage, and a back linkage. The carrier link couples the base plate to the back linkage while the full recline link couples the carrier link to the base plate. The control linkage is coupled to the base plate, the back linkage, and the footrest extension linkage and cooperates therewith to move the footrest mechanism between the open and closed positions. Further, the control linkage cooperates with the back linkage to move the backrest between the upright position and the fully reclined position.
Claims6
A linkage mechanism for a recliner chair having a footrest, a seat, back, a base, and a pair of spaced apart armrests, the linkage mechanism comprising:
- a recliner mechanism comprising:
- a base plate first and second ends, the base plate being fixedly coupled to the base that supports the recliner mechanism above an underlying surface;
- a carrier link having first and second ends, the first end of the carrier link being coupled with the first end of the base plate;
- a recline link having first and second ends, the first end being coupled with the carrier link at a position intermediate the first and second ends of the carrier link;
- a seat mount plate having a forward portion and a rear portion;
- the second end of the recline link being coupled with the seat mount plate at a position intermediate the forward and rear portions;
- the back linkage comprising:
- a back bracket pivotably coupled with the rear portion of the seat mount plate and to an upper portion of an intermediate link;
- the intermediate link having the upper portion and a lower portion;
- a lower link having a front, rear, and upper portion, the front portion pivotably coupled to the rear portion of the seat mount plate, the rear portion being pivotably coupled to lower portion of the intermediate link, and the upper portion being pivotably coupled to the second end of the carrier link;
- and
- a footrest mechanism coupled with the front portion of the seat mount plate;
- wherein the recliner mechanism operates to move the chair between a first position and a second position, and the second position and a third position;
- and
- wherein the interconnection of the recline between the carrier link and the seat mount plate causes the rear portion of the seat mount plate to rise at a greater rate than the forward portion of the seat mount plate when adjusting the recliner mechanism from the second position to the third position.
