[0016] The preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely for explaining the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0017] See Figures 1 to 4This utility model discloses an inflatable lumbar support for a car seat, including a mounting bracket mounted on a back spring support. The mounting bracket includes an upper frame 601 and a lower frame 603. The upper frame 601 is connected to the upper part of the back spring support, and the lower frame 603 is connected to the lower part of the back spring support. A support structure is provided between the mounting bracket and the back spring support. Multiple airbags 6 for adjusting the support state are provided between the upper frame 601 and the lower frame 603. The airbags 6 are connected by a middle plate 601 to ensure stability during use. An air pipe 604 is provided on the side of the airbag 6 to communicate with an air supply device. The air supply device includes an air supply device located on the back of the support plate. The air distribution device 303 is located on the back of the support plate 3. The inlet of the air distribution device 303 is connected to an air tank 4. A fixing rod 401 is located on the side of the air tank 4. The fixing rod 401 is fixed to the connecting rod 1 by a connecting buckle. Multiple connecting pipes 402 are located at the bottom of the air distribution device 303 for supplying air. The air pipe 604 is connected to the airbags 6 on the seat and inflates multiple airbags 6 respectively, controlling the overall structure of the airbags 6. When in use, the air distribution device 303 adjusts the inflation volume of the airbags 6 in different positions according to the body shape of different drivers and passengers, so that the airbags 6 can fit the back of the human body more closely and provide a more comfortable driving experience.

[0018] The supporting structure mainly includes key components such as connecting rods 1 (connected to the back spring bracket), reinforcing rods 2, support seats 5, support plates 3, and connecting blocks 301. It provides effective support and shock absorption for the human body while meeting the needs of intelligent seat adjustment. Connecting rods 1, as the main supporting framework of the seat back mesh, are arranged horizontally in multiple sections, with reinforcing rods 2 on both sides to enhance the overall structural stability. The middle section of each connecting rod 1 features a downward bend, which not only increases the fit of the seat back but also improves seating comfort. A central rod 101 runs through the middle of each connecting rod 1, making the entire connecting rod 1 mesh-like, increasing the overall load-bearing capacity and further enhancing the structural stability. A connecting ring is provided at the connection point between the connecting rod 1 and the reinforcing rod 2 for easy installation and to enhance the strength of the connection. Furthermore, the connecting rod 1 deforms under stress during use, allowing for a certain amount of deformation when the entire structure moves backward, reducing the impact of rigidity and ensuring safe use.

[0019] The bottom of the support seat 5 is fixed to the side panel of the seat back, and its two ends are set along the bottom of the connecting rod 1. It is connected to the connecting rod 1 by a fixing buckle 501. The end of the support seat 5 and the tail of the connecting rod 1 are not on the same plane to ensure the stability of the connection. The support seat 5 is bent backward to provide a connection point and to provide support for the overall structure, preventing the overall structure from falling and ensuring safety in use. The support seat 5 not only provides additional support for the connecting rod 1, but also enhances the stability of the entire seat back mesh structure.

[0020] The support plate 3 is located below the connecting rod 1 and the reinforcing plate, providing the main support surface for the lower part of the seat back. The upper part of the support plate 3 is provided with a connecting plate 302 for engaging the connecting rod 1, ensuring a stable connection between the connecting rod 1 and the support plate 3. The connecting block 301 is located on the side of the connecting plate 302, with its tail tilted towards the back. The connecting block 301 increases the connection point, ensuring the stability of the stressed part and increasing the stability of the support plate 3. This helps to distribute the pressure on the seat back and improves the durability of the seat, further enhancing the comfort of the seat.

[0021] The outer side of the connecting pipe 402 is equipped with a fixing member that connects to the support plate 3. Gas is supplied to the air distribution device 303 through the air tank 4, and then evenly distributed to the airbags in various parts of the seat back through the connecting pipe 402. This enables the seat back to be intelligently adjusted and comfortably supported according to different driving postures. It solves the problems of limited spring life and easy abnormal noise in the existing technology. Through innovative designs such as increasing the stability of the connecting rod 1 and the reinforcing rod 2, setting the support plate 3 and the connecting block 301, and introducing the air distribution device 303 and the air tank 4, the intelligent adjustment and comfort support of the seat back are realized. This not only improves the comfort and safety of the seat, but also meets consumers' needs for intelligent and personalized car seats.
