SEAT FRAME FOR VEHICLE

Right and left brackets coupling a seat back frame and seat cushion frame together are configured to adjust an amount of deformation upon impact absorption. A vehicle seat frame includes a seat cushion frame, seat back frame, coupling bracket configured to couple a cushion side frame as a side frame of the seat cushion frame on one side of the vehicle seat frame and a seat back side frame as a side frame of the seat back frame on the one side, and coupling bracket configured to couple a cushion side frame as a side frame of the seat cushion frame on the other side and a seat back side frame as a side frame of the seat back frame on the other side. Deformability upon impact absorption is different between a weak portion provided at the coupling bracket and a weak portion provided at the coupling bracket.
