A seat-frame of an extrusion molding type is provided to increase thermal stability and durability by cutting off the heat through an air layer formed in hollow bars composed of an aluminum molding material, to easily manufacture and install, and to reduce the weight of a vehicle, such as a train or a subway, by minimizing additional cushions. In a seat-frame installed in a vehicle, the seat-frame is shaped like a board to sit on and extrusion-molded with aluminum. The extrusion molding type seat-frame comprises a hollow board frame(20) composed of insulating spaces(22) and reinforcing ribs(21); a hollow back rest frame(30) combined with the inner and upper end of the board frame and extrusion-molded with aluminum; an insulating pad installed on bottom surface of the board frame to cut off the heat out of a heating means installed under the board frame; and a backside supporting frame(40) composed of a back rest combining unit installed on the inner panel of the vehicle to fix the back rest frame connected on back end of the board frame and combining protruded pieces(41) for fixing the board frame. |
