Abstract: A rocker-recliner-style seating unit (rocker recliner) that includes a linkage mechanism adapted to move the rocker recliner between closed, extended, and reclined positions is provided. The rocker recliner is powered by a linear actuator that facilitates automated adjustment of the linkage mechanism. This adjustment of the linear actuator is sequenced into a first phase and a second phase.

A stroke in the second phase acts to adjust the 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 the linkage mechanism commences adjustment within the second phase only once the first-phase adjustment is substantially complete.
