[0029] Example:

[0030] Reference Figures 1-4 The system includes a lumbar support base 1, which serves as the mounting base for connecting the lumbar support assembly to the office chair, fixing the lumbar support assembly to the rear of the office chair. A guide rail 2 provides a moving track for the electric slider 3, allowing the electric slider 3 to slide smoothly on it, thereby adjusting the vertical position of the lumbar support. The electric slider 3 drives the lumbar support assembly to move within the limited range of the guide rail 2, ensuring the lumbar support assembly is precisely aligned with the user's waist. A connecting plate 4 connects the electric slider 3 and the electric telescopic rod 5, serving to transmit force and fix components, ensuring a secure connection between all parts. The electric telescopic rod 5 adjusts the forward and backward movement of the lumbar support assembly through its telescopic motion. The position of the lumbar support changes the distance and fit between the lumbar support and the user's waist to adapt to different sitting postures and forward or backward leaning positions. This allows the lumbar support components to fit snugly and effectively distribute lumbar pressure. The electric rotating shaft 6 can drive the lumbar support components to rotate around the shaft, adjusting the angle of the lumbar support components to better adapt to the physiological curve of the human waist and different sitting angles. The lumbar support frame 7 serves as the skeleton structure of the lumbar support, providing the overall shape and stability of the lumbar support. By installing components on this device to adjust the position of the lumbar support components, the lumbar support airbag can be precisely aligned with the user's waist, providing snug support and effectively distributing lumbar pressure, reducing the risk of lumbar injury.

[0031] Reference Figure 3and Figure 4 The airbag lumbar support body 8 adjusts its shape and firmness by inflating and deflating air, providing close support for the waist, reducing the burden on the waist muscles, and maintaining the physiological curvature of the lumbar spine. The carbon nanotube flexible heating pad 9 generates heat when powered on, providing warmth to the airbag lumbar support body 8, promoting blood circulation in the waist, relieving waist muscle tension, and the carbon nanotube flexible heating pad 9 is made of flexible material, which can change its shape with the inflation and deflation of the airbag lumbar support body 8.

[0032] Reference Figure 4 The air pump 10 inflates the airbag lumbar support body 8 with gas. By compressing air and delivering it to the airbag lumbar support body 8, the airbag can inflate to a suitable size and firmness, thereby providing support for the user's waist. The electromagnetic exhaust valve 11 is used to control the release of gas from the airbag lumbar support body 8. When it is necessary to reduce the firmness of the airbag lumbar support body 8, the electromagnetic exhaust valve 11 will open, allowing the gas in the airbag lumbar support body 8 to be released slowly or quickly, thereby adjusting the pressure and shape of the airbag lumbar support body 8.

[0033] Reference Figure 1 and Figure 2 The backrest frame 12 serves as the support structure for the backrest, providing a stable frame for the entire backrest and bearing the pressure of the human back. The backrest fabric 13 is made of mesh material, which comes into direct contact with the human back, providing a soft and comfortable touch.

[0034] Reference Figure 1 and Figure 2 The chair base 14 provides a stable support point for the chair, bearing the weight of the chair and its user, ensuring the stability and safety of the chair. The chair base 14 contains a PLC controller and a battery, and is electrically connected to relevant electrical components through cables, thereby ensuring the normal operation of the device. The headrest 15 is used to support the user's head and neck, reduce pressure on the head and neck, maintain the natural curve of the cervical spine, and relieve cervical fatigue caused by prolonged sitting.

[0037] Reference Figure 1 and Figure 2 The five-pointed star claw 20 is part of the chair and is shaped like a five-pointed star. It provides a stable support point to ensure the stability of the chair during use. The casters 21 can rotate freely within 360 degrees, allowing the chair to change direction without changing the overall orientation of the chair.

[0038] The implementation principle of an embodiment of an airbag-supported comfort lumbar support office chair according to this application is as follows: The lumbar support base 1 serves as the mounting base for connecting the lumbar support assembly to the office chair, and is used to fix the lumbar support assembly to the rear side of the office chair. The guide rail 2 provides a moving track for the electric slider 3, allowing the electric slider 3 to slide smoothly on it, thereby realizing the vertical position adjustment of the lumbar support. The electric slider 3 is used to drive the lumbar support assembly to move within the limited range of the guide rail 2, so that the lumbar support assembly can be accurately aligned with the user's waist. The connecting plate 4 connects the electric slider 3 and the electric telescopic rod 5, and plays the role of transmitting force and fixing components, ensuring that the connection between the various components is firm. The electric telescopic rod 5 moves through extension and retraction. Adjusting the front and back position of the lumbar support component changes the distance and fit between the lumbar support and the user's waist to adapt to different sitting postures and forward or backward leaning positions. This allows the lumbar support component to provide close-fitting support, effectively dispersing lumbar pressure. The electric rotating shaft 6 can drive the lumbar support component to rotate around the shaft, adjusting the angle of the lumbar support component to better adapt to the physiological curve of the human waist and different sitting angles. The lumbar support frame 7 serves as the skeleton structure of the lumbar support, providing overall shape and stability. By installing components for adjusting the position of the lumbar support component in this device, the lumbar support airbag can be precisely aligned with the user's waist, providing close-fitting support and effectively dispersing lumbar pressure, reducing the risk of lumbar injury.
