Abstract:
A linkage mechanism for a rocker-recliner chair having a base, a seat, a footrest, a backrest and a headrest, said linkage mechanism comprising:a rocker cam assembly mounted on the base; a seat mounting linkage coupling the seat to the rocker cam assembly; a footrest extension linkage coupled with the seat mounting linkage and having the footrest mounted thereto; a drive linkage coupling said seat mounting linkage with said footrest extension linkage, said drive linkage adapted to drive said footrest extension linkage from a retracted position to an extended position; a back support linkage coupled with said seat mounting linkage and having the backrest mounted thereto; a headrest mounting linkage coupled with said back support linkage and having the headrest coupled thereto; a pop-up linkage including a headrest drive link, a headrest bell crank and a toggle link, said headrest bell crank coupling said headrest drive link to said toggle link and being pivotally coupled with said back support linkage, said headrest drive link being coupled with said drive linkage, and said toggle link being coupled with said headrest mounting linkage; and a rock blocker linkage coupled with said seat mounting linkage and the base, wherein a portion of said rock blocker linkage is selectively coupled with said base to prevent the chair from rocking relative to the base when said footrest extension linkage is in the extended position, wherein said headrest drive linkage, said headrest bell crank and said toggle link cooperate to move said headrest mounting linkage to a support position when said drive linkage moves said footrest extension linkage to the extended position, and wherein said headrest drive linkage, said headrest bell crank and said toggle link cooperate to move said headrest mounting linkage to a closed position when said footrest extension linkage is moved to the retracted position.
