Problems solved by technology

In such a structure, when the seat back frame receives a forward load from the rear at the lower portion, the load acts on the central portion frame in the axial direction of the central portion frame, and therefore, the central portion frame can The above-mentioned load is effectively supported, but when the seat back frame receives a forward load on the upper part (a position above the reclining mechanism), a large torque acts on the rear frame from the seat back frame via the reclining mechanism , in order to strengthen the torsional rigidity of the rear frame with a central frame, it is necessary to make a central frame with a large diameter, and it is difficult to reduce the weight
