Abstract:
A power lift lumbar support system for a furniture member includes a lumbar pad. A scissoring portion is rotatably connected to the lumbar pad and moves the lumbar pad between a fully retracted and a fully extended position. A lumbar actuation portion is connected to the scissoring portion and drives the scissoring portion using a powered actuator to displace the lumbar pad. A carrier support rod has first and second carriers slidably disposed on the carrier support rod. The scissoring portion is connected to each of the first and second carriers. Displacement of the first and second carriers toward each other operates through the scissoring portion to displace the lumbar pad away from the carrier support rod and toward the fully extended position.
