Abstract

The invention discloses a linkage mechanism and a reclining chair having the same. The linkage mechanism has a forward mounting pivot for attaching the actuator to the footrest linkage and a rearward mounting unit for attaching the actuator to the lever link. The lever link is pivotally connected to the base mounting plate at the fulcrum pivot point. The fulcrum pivot attachment point is operably non-movable when the linkage mechanism is driven from one position to another position of the reclining chair, thereby, improving the operation stability of the reclining chair.
