  • Patent number: 10814757
    Abstract: A seatback frame for vehicles is disclosed. The seatback frame for vehicles has a simple structure without bracket structures used to install a conventional seatback frame and thus achieves cost reduction and weight reduction. In particular, the seatback frame is segmented into several parts having different rigidities so that only a part, on which load is concentrated, is set to have high strength and thus avoids overdesign for excessively high strength of an unnecessary part.
