Abstract:
A powered actuator system for moving a lumbar support bar of a furniture piece, which comprises a single dual-directional powered actuator (106) mounted upon a foundation base (102) with respect to which the lumbar support bar (104) is to be moved between fully extended and fully retracted positions, as well as a multiplicity of intermediate positions. The single dual-directional powered actuator (106) is operatively connected to a first end portion of the lumbar support bar (104) by means of a first main lifting link (126), while a synchronization bar (124) operatively interconnects the first main lifting link (126) with a second main lifting link (138) operatively connected to a second end portion of the lumbar support bar (104).
