SEAT FRAME OF VEHICLE

摘要

Introduced is a seat back frame of a vehicle comprising first channel parts and second channel parts. The first channel parts are arranged on the top and bottom of a seat back panel in a horizontal direction, have a cross section at the seat back panel, and protrude frontwards to form a channel shape. The second channel parts are arranged on both sides of the seat back panel and are installed between the first channel parts formed on the top and bottom of the seat back frame in a longitudinal direction to be integrated with the first channel parts. The flanges of the second channel parts are extended frontwards in the seat back panel, and the ends of the flanges are bent to the center of the seat back panel to be extended to the center. Thereby, the second channel parts form a channel shape having one open surface.
