Headrest pop-up linkage for a chair mechanism

A linkage mechanism for a rocker-recliner chair having a base, a rocker cam assembly mounted on the base, a seat, a footrest, a backrest and a headrest, said linkage mechanism comprising:

• a seat mounting linkage coupling the seat to the rocker cam assembly;
• a footrest extension linkage coupled with the seat mounting linkage and adapted to have 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 adapted to have the backrest mounted thereto;
• a headrest mounting linkage coupled with said back support linkage and adapted to have the headrest coupled thereto;
• and
• a pop-up linkage including a headrest drive link having upper and lower portions, a headrest bell crank having first and second end portions, and a toggle link, said lower portion of said headrest drive link being coupled with said drive linkage and said upper portion being coupled with said first end portion of said headrest bell crank, said toggle link being coupled with said second end portion of said headrest bell crank and said headrest mounting linkage, and an intermediate portion of said headrest bell crank being pivotally coupled with said back support linkage,
• wherein said headrest drive link rotates said headrest bell crank in a counterclockwise direction relative to said back support linkage as said drive linkage drives said footrest extension linkage to the extended position thereby rotating said headrest mounting linkage in a counterclockwise direction relative to said back support linkage to place said headrest mounting linkage in a support position, and wherein said headrest drive link rotates said headrest bell crank in a clockwise direction relative to said back support linkage when said footrest extension mechanism is moved to a retracted position thereby rotating said headrest mounting linkage in a clockwise direction relative to said back support linkage to place said headrest mounting linkage in a closed position.

A linkage mechanism for a rocker-recliner chair having a base, a rocker cam assembly mounted on the base, a seat, a footrest, a backrest and a headrest, said linkage mechanism comprising:

• 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;
• and
• a pop-up linkage including a headrest drive link having upper and lower portions, a headrest bell crank having first and second end portions, and a toggle link, said lower portion of said headrest drive link is coupled with said drive linkage and said upper portion is coupled with said first end portion of said headrest bell crank, said toggle link is coupled with said second end portion of said headrest bell crank and said headrest mounting linkage, and an intermediate portion of said headrest bell crank is pivotally coupled with said back support linkage at a point located rearwardly and below the connection between said upper portion of said headrest drive link and said first end portion of said headrest bell crank when said footrest extension linkage is in the extended position,
• wherein said lower portion of said headrest drive link moves forwardly as said drive linkage drives said footrest extension linkage to the extended position whereby said upper portion of said headrest drive link rotates said headrest bell crank in a counterclockwise direction relative to said back support linkage to place said headrest mounting linkage in a support position, and wherein said lower portion of said headrest drive link moves rearwardly as said footrest extension linkage is moved to a retracted position whereby said upper portion of said headrest drive link rotates said headrest bell crank in a clockwise direction relative to said back support linkage to place said headrest mounting linkage in a closed position.

A rocker recliner chair having a base, a seat, a backrest, a headrest and a pair of linkage mechanisms for supporting the seat and backrest for movement between upright, intermediate and fully reclined positions, each of said linkage mechanisms comprising:

• 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, said backrest support linkage capable of moving relative to said seat mounting linkage to place the chair in the fully reclined position after said footrest extension linkage is placed in the extended position;
• a headrest mounting linkage coupled with said back support linkage and having the headrest coupled thereto;
• and
• a pop-up linkage including a headrest drive link having upper and lower portions, a headrest bell crank having first and second end portions, and a toggle link, said lower portion of said headrest drive link is coupled with said drive linkage and said upper portion is coupled with said first end portion of said headrest bell crank, said toggle link is coupled with said second end portion of said headrest bell crank and said headrest mounting linkage, and an intermediate portion of said headrest bell crank is pivotally coupled with said back support linkage,
• wherein said headrest drive link rotates said headrest bell crank in a counterclockwise direction relative to said back support linkage as said drive linkage drives said footrest extension linkage to the extended position thereby placing said headrest mounting linkage in a support position, wherein said pop-up linkage operates to maintain the position of said headrest mounting linkage relative to said back support linkage as the chair moves to the fully reclined position, and wherein said headrest drive link rotates said headrest bell crank in a clockwise direction relative to said back support linkage when said footrest extension mechanism is moved to a retracted position thereby placing said headrest mounting linkage in a closed position.

• a footrest extension linkage coupled with the seat mounting linkage and having the footrest mounted thereon;
• a drive linkage coupling said seat mounting linkage with said footrest extension linkage, said drive linkage adapted to drive said footrest extension linkage from an retracted position to an extended position;
• a back support linkage coupled with said seat mounting linkage and having the backrest mounted thereto, said backrest support linkage capable of moving relative to said seat mounting linkage to place the chair in the fully reclined position after said footrest extension linkage is placed in the intermediate position;
• a headrest mounting linkage coupled with said back support linkage and having the headrest coupled thereto;
• means for rotating said headrest drive link in a counterclockwise direction relative to said back support linkage as said drive linkage drives said footrest extension linkage to the extended position to place said headrest mounting linkage in a support position;
• means for maintaining the position of said headrest mounting linkage relative to said back support linkage as the chair moves to the fully reclined position;
• and
• means for rotating said headrest bell crank in a clockwise direction relative to said back support linkage when said footrest extension mechanism is moved to a retracted position to place said headrest mounting linkage in a closed position.
