An adjustable lumbar support for chairs and vehicle seats, which provides an adjustable contour to the seat back for varying degrees of lumbar support to the seat occupant is disclosed. The lumbar support includes a mounting base, a lumbar plate, and a pair of articulated linkage arms. Each of the linkage arms includes an upper and lower segment, which are pivotally connected by an elbow joint. The lower segments of each linkage arm are pivotally connected to the mounting base and the upper segments of each linkage arm are pivotally connected to the lumbar plate. A Bowden cable is connected to the linkage arms at the elbow joints, such that extending or retracting the cable pulls or pushes the elbow joints together or apart to actuate the lumbar support. The linkage mechanism composed of the linkage arms and the six pivotal joints allows the lumbar plate a limited degree of pivotal movement between its fully extended and fully retracted positions.
