[0029] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0030] See Figure 1-3 As shown, an adaptive adjustable lumbar support includes a mounting plate 1 and a lumbar support assembly 2. A mounting frame 3 is fixedly connected to the surface of the mounting plate 1. Adjustment plates 4 are fixedly connected to both sides of the lumbar support assembly 2. Adjustment sleeves 5 are sleeved on the outer ends of the adjustment plates 4. A connecting bushing 6 is fixedly connected to the surface of the adjustment sleeves 5. The lumbar support assembly 2 includes a lumbar support body 7 and a spring cylinder 10 on its surface. A support part 8 and a pressure-bearing part 9 are provided on the surface of the lumbar support body 7.

[0031] In this embodiment of the utility model, the surface of the mounting plate 1 is curved and raised, and its top end is also set with an arc-shaped angle. The mounting frame 3 is set with a rectangular frame raised along the surface of the mounting plate 1, and the edges of the mounting frame 3 are all set with arcs. Through slots are opened on both sides of the surface of the mounting plate 1 corresponding to the adjustment plate 4. The mounting plate 1 and the raised mounting frame 3 are used to facilitate the installation and support of the lumbar support component 2. The through slots opened on both sides of the surface of the mounting plate 1 facilitate the limiting and fixing of the adjustment plate 4.

[0032] The lumbar support body 7 is rectangular in shape and consists of two sets of curved rectangular plates. The adjustment plate 4 is trapezoidal and connected to the back of the lumbar support body 7 at both sides. It is also embedded in the through slots on both sides of the mounting plate 1. The adjustment plate 4 and the adjustment sleeve 5 are movably connected. The adjustment sleeve 5 is trapezoidal and is longitudinally connected to the adjustment plate 4. The movably connected adjustment plate 4 and adjustment sleeve 5 achieve the effect of longitudinal adaptive connection according to the force of the lumbar support body 7.

[0033] The support part 8 is rectangular and concave, with multiple sets of through holes on its surface, and rubber support cylinders protruding at the corners. The pressure-bearing part 9 is located in the center of the front of the lumbar support body 7, and it is arc-shaped and protruding. The pressure-bearing part 9 is filled with inflatable sponge and silicone particles, and a circular sponge pad is protruding on the surface of the pressure-bearing part 9. Through the support part 8 and the pressure-bearing part 9, and in conjunction with the rubber support cylinders on the surface of the support part 8, the effect of conforming and supporting the lumbar curve of the user is achieved.

[0034] Four sets of spring cylinders 10 are provided, located at the four corner positions of the lumbar support body 7. Their bottom ends are connected to the corner positions of the mounting plate 1. The spring cylinder 10 includes a sleeved plastic cylinder and its built-in compression spring.

[0035] The entire device is connected to the external support by the connecting bushing 6 on the surface of the adjusting sleeve 5. When the device is in use, when the lumbar support body 7 comes into contact with the user's waist, the raised pressure-bearing part 9 is first subjected to force, supporting the user's waist. At the same time, the force on the pressure-bearing part 9 causes the outer ends of the two separate lumbar support body 7 to be raised, which can then more effectively fit the area around the user's lumbar spine and provide close support. The spring cylinder 10 adjusts adaptively according to the force on the lumbar support body 7, and the adjusting plate 4 slides adaptively in the adjusting sleeve 5 according to the force on the lumbar support body 7, ensuring the stability of the position adjustment at both ends of the lumbar support body 7.
