A combination lumbar bolster system for attachment to a vehicle seat frame comprises a lumbar support having a flat position and a deployed position, wherein the deployed position is forward of the flat position; a pair of lateral bolsters each having a resting position and an extended position, wherein the extended position is further from the seat frame than the resting position; at least one traction cable operably attached to at least one of the lumbar support and the lateral bolsters; and at least one spring. The traction cable moves the lumbar support between the flat position and the deployed position and the lateral bolsters between the resting positions and the extended positions such that the movements of the lumbar support and the bolsters is coordinated, and the spring opposes the movement of the traction cable. |
