A unitized back plate and lumbar support device for a seat including a back plate, a housing with a channel, which housing is fixedly attached to the back plate, and an extending paddle. The extending paddle has a free end with a pressure surface, the surface being a load bearing element proximal to a seat occupant, and the extending paddle has an encapsulated end in extendible communication with the channel in the housing. An actuator mediates travel of the extending paddle between a substantially retracted position and an extended position.
