Rocker-recliner-style and glider-recliner-style seating units that include linkage mechanisms for adjusting the respective seating units between closed, extended, and reclined positions are provided. The seating units are each powered by a linear actuator that facilitates automated adjustment of the respective linkage mechanisms. This adjustment of the linear actuator is sequenced into a first phase and a second phase. A stroke of the linear actuator in the first phase acts to adjust a linkage mechanism between the closed and extended positions by extending or retracting ottoman(s) attached to a footrest assembly. A stroke in the second phase acts to adjust a linkage mechanism between the extended and reclined positions by translating a seat-mounting plate forward or rearward at a consistent inclination angle while, concurrently, tilting a back-mounting link. Accordingly, the phase sequencing ensures that each linkage mechanism commences adjustment within the second phase only once the first-phase adjustment is substantially complete. |
