PURPOSE: A lumbar support for adjusting the position of a vehicle is provided to improve comfortableness for a passenger by adjusting the position of the lumbar support according to the body shape of the passenger, and to support the lumbar of the passenger by injecting cold or hot blast from an air conditioner to the lumbar support. CONSTITUTION: A position adjustable lumbar support is composed of a position detecting sensor(11) installed in a seat track of a seat(100) to measure the position of the seat; an ECU(Electronic Control Unit,13) memorizing the position from the position detecting sensor and controlling rotation of a motor(12); a rack(14a) and a pinion gear(14b) driven by rotating the motor; an air tube(15) attached to the rack gear and linearly moved up and down with the rack gear to adjust the position and support the lumbar of the passenger; control valves(18a,18b) installed to an inlet(16) and an outlet(17) to regulate air flow by a control switch(19); and an air conditioner(20) connected to the inlet to inject hot or cold blast to the air tube. Comfortableness is improved by varying the position of the lumbar support.
