[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example

[0025] See Figures 1 to 3 As shown, a buffer type foam waist pad includes a foam waist pad body 1 and a covering sleeve 2 covering the outside of the foam waist pad body. In this embodiment, the covering sleeve is a layout sleeve or a leather sleeve. At the same time, in the actual application process, a cavity 3 is arranged in the foam waist pad body, and a rubber layer 4 is fixed on the inner wall of the cavity; a first arch plate 5 and a second arch plate 6 are arranged in the cavity; when processed and used, the two ends of the first arch plate and the second arch plate are fixedly connected, and the arched parts of the first arch plate and the second arch plate are arranged in reverse; the rubber layer on the symmetrical inner wall of the cavity is respectively fixed on the arched outer surface of the first arch plate and the second arch plate. The rubber layer can prevent the first arch plate and the second arch plate from damaging the foam waist pad body. In order to facilitate processing and use, the foam waist pad body is first processed into two halves. After the first arch plate and the second arch plate are assembled, the connection between the two halves of the foam waist pad body is foamed and connected into a whole.

[0026] In actual application, a mounting support 7 is provided on the back of the foam lumbar pad body, and the mounting support is a plastic plate or a wooden plate. The foam lumbar pad body is fixed on the mounting support; two limiting convex strips 8 are provided on the mounting support. In this embodiment, the height of the limiting convex strips is relatively small, so when in use, due to the existence of the first arch plate, the second arch pole and the foam lumbar pad body, they will not directly contact the waist, thereby not affecting the comfort of use. The limiting convex strips extend into the cavity and are located on both sides of the cavity; when installing, the mounting support can be fixed to the backrest by screws or other means, which improves the convenience of installation and use, and facilitates disassembly and maintenance operations. At the same time, the first arch plate and the second arch plate are located between the two limiting convex strips, and when the first arch plate and the second arch plate are compressed, the two ends abut against the side of the limiting convex strips to limit. The limiting convex strip is mainly used for compressing the first and second arched plates and stretching the two ends when the human waist is leaning forward. The two ends can be limited by the limiting convex strip, thereby preventing the two ends of the first and second arched plates from excessively stretching and damaging the foam lumbar pad body, thereby improving the stability of use.

[0027] In actual application, the first arch plate and the second arch plate are both metal plates with a thickness of 0.1-0.3 mm. The width of the first arch plate and the second arch plate matches the width of the cavity. The arching curvature of the first arch plate and the second arch plate matches the shape of the human waist. Through the above structure, when in use, the human waist is pressed against the foam waist pad body and on the arching curvature of the first arch plate or the second arch plate, and no local bulge will occur to affect the comfort of use. At the same time, it is also conducive to making the force uniform everywhere, which is conducive to improving the comfort of use.

[0028] The utility model has positive effects: the structure of the utility model is reasonably arranged, a cavity is arranged in the foam waist pad body, and a first arch plate and a second arch plate are arranged in the cavity. When in use, the first arch plate and the second arch plate will be squeezed and stretched to both sides. After resetting, the first arch plate and the second arch plate are reset under the action of their own elastic force, thereby effectively preventing the foam waist pad body from collapsing, which is beneficial to improving the stability and reliability of use, and has strong applicability and good practicality.

[0029] Moreover, in actual application, it also has an installation support, and the two ends of the installation support are provided with limiting convex strips. The first arch plate and the second arch plate are limited by the limiting convex strips when the two ends are compressed and extended, which can prevent the first arch plate and the second arch plate from squeezing and damaging the foam lumbar pad body at both ends, which is beneficial to improving the effectiveness of use. In addition, by arranging a rubber layer on the inner wall of the cavity and matching the width of the first arch plate and the second arch plate with the width of the cavity, there will be no local bulge, which is also beneficial to improving the comfort of use, strong applicability and good practicality.

[0030] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification can also be directly processed according to existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0031] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. However, these obvious changes or modifications derived from the essential spirit of the present invention still fall within the scope of protection of the present invention.
