The invention discloses an automobile back row seat back framework which is integrally in a frame shape. The automobile back row seat back framework comprises a first beam, the right end of the first beam is connected with the upper end of a first longitudinal beam into a whole, the left end of the first beam is connected with the upper end of a fourth longitudinal beam into a whole, the lower end of the fourth longitudinal beam is provided with a bending part bending rightwards, a second longitudinal beam and a third longitudinal beam are respectively arranged between the first longitudinal beam and the fourth longitudinal beam, the upper end of the second longitudinal beam is welded to the middle of the first beam, the upper end of the third longitudinal beam is welded to the position close to the left end of the first beam, the bending part of the fourth longitudinal beam is welded with the left side of the third longitudinal beam, a second beam is welded between the middle of the first longitudinal beam and the middle of the second longitudinal beam, the lower end of the first longitudinal beam is welded to the right end of a third beam, the lower end of the second longitudinal beam is welded to the middle of the third beam, and the lower end of the third longitudinal beam or the lower end of the bending part of the fourth longitudinal beam is welded to the left end of the third beam. The back row seat back framework is simple in structure, low in manufacturing cost and high in performance.
