The invention discloses an automobile rear backrest seat framework welding assembly and a welding method thereof, and relates to the field of automobile seat frameworks, the automobile rear backrest seat framework welding assembly comprises a chair back framework assembly, the bottom end of the chair back framework assembly is movably connected with a seat cushion framework assembly, and the top end of the chair back framework assembly is fixedly connected with a headrest; a back plate is fixedly connected to the inner wall of the chair back framework assembly, and a movable groove is formed in the outer wall of the back plate in a penetrating mode. The two back supporting plates are used for supporting the upper portion of the chair back framework assembly, so that the back of a passenger is effectively supported, rotation of the waist supporting plate and the connecting shaft is matched with elastic contraction of the compression spring between the waist supporting plate and the back plate, the waist of the passenger is supported by the waist supporting plate, and the back of the passenger is supported by the back supporting plate. And the elastic deformation of the compression spring can adapt to the waist leaning strength of the passenger to realize self-adaptive angle strength feedback, so that the seat can provide excellent waist and back support, and the comfort of the passenger is improved.
