Abstract
A seatback frame for a vehicle is capable of preventing a passenger seated on a seat from being injured by a sharp edge of a side frame in the event of a collision of the vehicle. The seatback frame includes side frames installed to extend longitudinally in a vertical direction at opposite sides of the seatback frame, respectively, an upper frame joined to the side frames, and a lower frame joined to the side frames. Protrusions are formed at a surface of the upper frame while being spaced apart, by a predetermined distance, from edges present at edge portions of the side frames, respectively, to prevent the passenger from being injured by the edges.
