Problems solved by technology

Therefore, in the case where tension is concentrated on the connecting portion between the lower cross member and the rear side frame due to torsional bending moment, the connecting portion may break
Furthermore, according to DE10200404835A1, since the seatback frame is formed as a unit, the loads applied to it are distributed
However, the portion corresponding to the lower cross member forms a substantially flat surface shape, and therefore, the seat back frame for the vehicle may be suddenly crushed and deformed even if it is slightly deformed.
