Headrest pop-up linkage for a chair mechanism
Abstract:
A rocker recliner linkage mechanism having a headrest pop-up linkage is provided. The pop-up linkage includes a headrest drive link, a headrest bell crank and a toggle link. The headrest bell crank couples the headrest drive link to the toggle link and is pivotally coupled with a back support linkage. The headrest drive link is coupled with the drive linkage, and the toggle link is coupled with the headrest mounting linkage. The pop-up linkage utilizes the movement of drive linkage to move the headrest mounting linkage between the closed position to the support position as the chair moves between upright and intermediate positions. The pop-up linkage is also adapted to maintain the position of the headrest relative to the backrest as the chair is moved between intermediate and fully reclined positions.
