[0002] Seats are one of the key interior parts of automobiles, and integrated seats are currently the mainstream design trend of seats. In order to improve the grade of the entire vehicle and the overall sportiness of the seat, it is necessary to develop a new integrated seat headrest frame structure to achieve excellent functions and avant-garde appearance of the entire backrest frame. The existing integrated seat headrest frame solution is to eliminate the headrest plastic guide tube and directly weld the headrest metal tube to the backrest frame.

[0003] Publication number "CN214647763U" provides a car seat back frame, which strengthens the support strength of the back frame by arranging multiple support rods between the main pipe frames, thereby improving the service life and comfort of the seat.

[0004] However, the above technical solutions and the prior art have the following defects:

[0005] Although the car seat back frame has strengthened its supporting strength by setting up multiple support rods, no corresponding auxiliary reinforcement structure is set at the connection between the main frame and the reinforcing rod and the reinforcing plate. As a result, the car seat back frame is prone to cracking and deformation at the connection between the main frame and the reinforcing rod and the reinforcing plate during stress use. In addition, the car seat back frame and the headrest frame are set separately, which makes the headrest frame not strong and stable enough during use, and its stability in use needs to be improved.
