[0042] The middle airbag includes an upper airbag 1 and a lower airbag 2, and the upper airbag 1 and the lower airbag 2 are distributed up and down on the airbag plate 3. The side airbag includes a left airbag 4 and a right airbag 5, and the left airbag 4 and the right airbag 5 are arranged on the airbag plate 3. At both sides of the middle airbag, the two sides of the airbag plate 3 are bent, which can better fit with the side airbags and play a certain supporting role on the side airbags. The airbag plate 3 is a felt board, which is approximately rectangular. The physical properties of the felt board are stable, the sound insulation effect is good, and it is elastic, tough, wear-resistant, impact-resistant, tear-resistant, and not easy to be scratched. The setting of the felt board can support each airbag and prevent the airbag from contacting the grid of the car seat back to avoid the risk of being punctured.

[0043] The upper airbag 1, the lower airbag 2, the left airbag 4 and the right airbag 5 are all welded to the felt board by high-frequency welding. High-frequency welding equipment can be used for welding. High-frequency welding uses a high-frequency electromagnetic field to cause the molecules inside the material to collide violently with each other to generate high temperature to achieve the purpose of welding and melting. High-frequency welding has the advantages of high welding efficiency, high welding point quality and low production cost.

[0044] The air pump 6 is wrapped with a protective bag, which wraps the air pump 6 and has a certain protective effect. It can also reduce the noise of the air pump 6 and isolate the vibration of the air pump 6.

The two ends of the main trachea are respectively connected to the air pump 6 and the air valve group 8, the two ends of the upper trachea are respectively connected to the air valve group 8 and the upper air bag 1, the two ends of the lower trachea are respectively connected to the air valve group 8 and the lower air bag 2, and the two ends of the side trachea are respectively connected to the air valve group 8 and the side air bag.

[0046] The air valve group 8 includes multiple groups of inflation valves and deflation valves. The air pump 6 is connected to the air valve group 8 through the main air pipe. Each air bag is connected to the corresponding inflation valve and deflation valve in the air valve group 8 through the corresponding air pipe 7 to inflate or deflate the upper air bag 1, the lower air bag 2, and the side air bag. The high-pressure gas provided by the air pump 6 is controlled and divided through the air valve group 8, and is connected to the corresponding air bag through the upper air pipe, the lower air pipe, and the side air pipe, which is conducive to realizing independent control of multiple air bags.

[0047] By installing the upper air bag 1, the lower air bag 2, and the side air bags, and adjusting the inflation or contraction of each air bag through the air pump 6 and the air valve group 8, the user's demand for support is met. It is easy to operate, lighter, and more comfortable.

[0048] Reference Figures 1 to 4 A two-airbag car seat lumbar support and a car seat, including the two-airbag car seat lumbar support described above, and also including a car seat. By setting an airbag plate 3 on the car seat backrest, the two-airbag car seat lumbar support is combined with the car seat, so that the car seat has a two-airbag car seat lumbar support.

[0049] The airbag plate 3 is connected to the car seat back grid by rivets 9. The rivets 9 are Christmas tree buckles. The Christmas tree buckles are connected to the openings on the felt board. When the felt board is suspended and connected to the car seat back grid, the Christmas tree buckles are further installed on the mounting holes of the car seat back grid. By passing the Christmas tree buckles through the felt board and then installing them on the car seat back grid, the felt board can be quickly installed. The Christmas tree buckles are low in cost, quick to install, cause little damage to the felt board and the car seat back grid, and can achieve lossless installation and disassembly.

[0050] The two sides of the airbag plate 3 are bent so as to better fit with the side airbag and the car seat, thus providing a certain support to the side airbag.

[0051] The air pump 6 is installed and fixed to the car seat frame through a cable tie, which plays a role in fixing the air pump 6. The air pump 6 is connected to the car seat frame through the cable tie to achieve effective fixation. The cable tie connection is convenient, the connection stability is good, and the reliability is high.

[0052] An ECU housing 10 is fixed on the other side of the airbag plate 3, and the air valve group 8 is assembled in the ECU housing 10. At the same time, a circuit board is assembled in the ECU housing 10, and a control program is burned on the circuit board.
