The invention provides a reinforced structure of a seat backrest frame, wherein the bending resistance of the seat backrest frame connected with the support column part of a seat cushion frame via a tilt mechanism is improved. The reinforced structure of the seat backrest frame comprises a tubular support column part (12a) arranged on one side of the left and right sides of a seat backrest frame (12) supported on a seat backrest (5), and a lateral frame (71) combined with the support column part (12a). The lateral frame (71) is used for supporting a tilt mechanism (4) through inclined brackets (13, 13'). In the reinforced structure of the seat backrest frame, the lateral frame (71) with a U-shaped cross section is internally provided with the support column part (12a). Meanwhile, the rear sidewall of the lateral frame (71) is welded with the support column part (12a). A reinforced member (72) is welded onto the support column part (12a) and the lateral frame (71).
