[0018] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings.

[0019] Example:

[0020] The attached drawings show a specific implementation of an ergonomic flexible lumbar support of the utility model, which mainly includes a lumbar support body 1. The lumbar support body 1 adopts a three-area support planning. Figure 2 , Figure 3 As shown, the middle part of the front of the lumbar support body 1 is concave to form a spinal force line support area 11, and the two sides of the spinal force line support area 11 extend to form lumbar muscle lateral inclusion areas 12 respectively, and the height of the lumbar muscle lateral inclusion areas 12 is higher than the height of the spinal force line support area 11.

[0021] In this embodiment, combined with Figures 1 to 3 The lateral lumbar muscle inclusion areas 12 on both sides are inclined to the middle spinal force line support area 11 to form an inclusion structure. The upper parts of the spinal force line support area 11 and the lateral lumbar muscle inclusion areas 12 are gradually inclined close to the back of the lumbar support body 1, and the back of the lumbar support body 1 is convex. The overall shape of the lumbar support body 1 can achieve full inclusion and support of the back chest, waist and sacrum, so that the thoracic, lumbar and sacral vertebrae are always in the best ergonomic position.

[0022] The lumbar support body 1 includes an internal filling body 2 and an external wrapping body 3 for wrapping and shaping. The external wrapping body 3 is made of a flexible material, and includes an external surface 31 and a plurality of hollow portions 32 formed on the external surface 31. The thickness of the material used for wrapping and shaping the surface of the external surface 31 is 1 mm.

[0023] The filling body 2 and the outer wrapping body 3 are connected to each other, and the filling body 2 is also made of flexible material. Figure 4 The figure shows a partial structural schematic diagram of the filling body, which mainly includes a plurality of interconnected flexible support modules 21, and two adjacent flexible support modules 21 are staggered up and down. In this embodiment, each flexible support module 21 includes one or two rows of wavy elastic bodies 21a, and the wavy directions of the wavy elastic bodies 21a in the same row of the same module are the same and are spaced up and down, and the wavy directions of the wavy elastic bodies 21a in two adjacent rows of the same module are opposite and interconnected. The wavy directions of the wavy elastic bodies 21a interconnected between two adjacent flexible support modules 21 are opposite.

[0024] In this embodiment, whether it is the connection between the wavy elastic bodies 21 a in the same flexible support module 21 or the connection between the wavy elastic bodies 21 a of two flexible support modules 21 , both adopt a partially interlocking connection method.

[0025] When the lumbar support of the utility model is used, it is placed on an office chair, gaming chair or other usage scenarios. The middle spinal force line support area 11 can provide reasonable physiological curvatures of the chest, waist and sacrum, and the lateral lumbar muscle inclusion areas 12 on both sides can expand the overall back force area, while providing physiological curve support, reducing the discomfort caused by single-point pressure. The internal filling of the lumbar support adopts a self-created wavy space support structure, which makes full use of physical properties such as material elasticity, spatial physical support type, and physical mechanical space yield characteristics to achieve different purposes of deformation amounts in different pressure directions, while providing natural and soft support force, helping to open the joint gap and relax the muscles and ligaments on both sides of the chest, waist and sacrum. The lumbar support of the utility model has good overall comfort and is ergonomically designed for fit.

[0026] Of course, the above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any modifications made according to the spirit of the main technical solution of the utility model should be included in the protection scope of the utility model.
