[0030] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0031] like Figures 1 to 4 As shown, the lumbar support cushion described in the present invention includes a lumbar support cushion body 100, which is characterized in that it includes: a cushion portion 10, a connecting portion 20 and a backrest portion 30 connected in sequence, the cushion portion 10, the connecting portion 20 and the backrest portion 30 are an integral structure formed by integral injection molding, and the cushion portion 10 has an upwardly raised protrusion 11 at one end away from the connecting portion 20, and the protrusion 11 extends in an arc shape to both sides, and both sides of the cushion portion 10 are upwardly tilted, and recessed portions 12 are respectively formed between the protrusion 11 and the two sides of the cushion portion 10; the left and right sides of the backrest portion 30 extend forward in an arc shape to form a covering structure 32; wherein, a plurality of soft pads 40 are provided on the cushion portion 10 and the backrest portion 30.

[0032] It is understandable that the seat cushion part 10 is located at the lower part of the lumbar support seat cushion main body 100 and contacts the human buttocks. One end of the seat cushion part 10 far from the connecting part 20 has a raised part 11 that bulges upward. The raised part 11 extends in an arc shape to both sides to fit the human legs. Both sides of the seat cushion part 10翘向上, forming a recessed part 12 between the raised part 11, which helps to fix the sitting posture and prevent sliding. The connecting part 20 connects the seat cushion part 10 and the backrest part 30 and plays a transitional role. The shape of the connecting part 20 can be designed according to ergonomics to provide better comfort. The backrest part 30 is located at the upper part of the lumbar support seat cushion main body 100 and contacts the human back. The left and right sides of the backrest part 30 extend forward in an arc shape to form a covering structure 32, which can better fit the curve of the human back and provide comprehensive support. The soft pad 40 is arranged on the seat cushion part 10 and the backrest part 30. By increasing the softness of the contact surface, it improves comfort, reduces the fatigue caused by sitting for a long time, and can effectively support the waist and evenly disperse the pressure on the buttocks. The material of the soft pad 40 can be sponge, memory foam, etc.

[0033] Specific embodiments are as follows Figure 4 As shown, preferably, the connecting part 20 is bent in an arc shape, and the two sides of the connecting part 20 are arranged in a wavy shape to enhance the structural strength of the lumbar support seat cushion main body 100.

[0034] The connecting part 20 is not a simple planar structure but is bent in an arc shape so that it can better fit the curve of the human waist and provide a more ergonomic design. The two sides of the connecting part 20 are arranged in a wavy shape, which is equivalent to a reinforcing rib and can enhance the strength and stability of the connecting part. At the same time, it can also play a certain supporting role and further improve the comfort of the seat cushion.

[0035] Compared with the reinforcing rib, the wavy structure of the connecting part 20 is easier to injection mold.

[0036] Preferably, several crescent-shaped through holes 13 are provided in the seat cushion part 10.

[0037] Specifically, its shape cooperates with the soft pad 40 to form the "field" character structure of the "rich" character.

[0038] Preferably, a circular opening 31 is provided in the middle of the backrest part 30.

[0039] A circular opening 31 is provided in the middle of the backrest part 30. This opening 31 and the through hole 13 can play a role in ventilation and air permeability, increasing the comfort of the seat cushion. Especially in the hot summer, it can effectively reduce the stuffy feeling.

[0040] More specifically, the circular opening 31 cooperates with the shape of the soft pad 40 to form the "mouth" shape of the "rich" character. The circular opening 31 can also play a certain decorative role and make the appearance of the seat cushion more beautiful.

[0041] For example Figure 1 As shown, preferably, the soft pads 40 are arranged in a specific segmented pattern on the lumbar support cushion,

[0042] Among them, the soft pads 40 located in the backrest part 30 form a rectangle with a wider upper part and a narrower lower part, covering the lumbar region of the back; the soft pads 40 located in the seat part 10 form a square, covering the buttocks region.

[0043] More specifically, the soft pads 40 are arranged in the shape of the Chinese character "Fu" on the lumbar support cushion. Among them, the upper part, the horizontal stroke, and the lower part of the character "Fu" are arranged in the backrest part 30, and the "field" part of the character "Fu" is arranged in the seat part 10.

[0044] The soft pads 40 are no longer randomly distributed, but arranged in the shape of the character "Fu". This unique arrangement not only has an aesthetic effect, but also can more effectively support the waist and back, providing better comfort.

[0045] The zoning of the soft pads 40 corresponds each part of the character "Fu" to the seat part and the backrest part respectively, enabling the soft pads to better adapt to the support requirements of different parts of the human body. The "Fu" - shaped design is unique and aesthetic, with high recognition.

[0046] Preferably, the shape of the soft pad 40 is adapted to the shape of the lumbar support cushion main body 100.

[0047] The shape of the soft pad 40 is customized according to the shape of the lumbar support cushion main body 100, improving the adaptability of the product.

[0048] Preferably, the lumbar support cushion main body 100 is made of a hybrid material of ABS and PP materials.

[0049] Specifically, the ABS material has good toughness and impact strength, while the PP material has relatively high rigidity. The combination of the two can improve the overall strength and durability of the lumbar support cushion. The PP material has a relatively low density, which can effectively reduce the weight of the lumbar support cushion and improve its portability. Both the ABS and PP materials have good heat resistance, which can ensure the stability of the lumbar support cushion during long - term use. The processing performance of the ABS and PP materials is good, and various molding processes such as injection molding and extrusion can be used, facilitating mass production. Compared with other high - performance materials, the cost of the ABS and PP materials is relatively low, which is beneficial to reducing the production cost of the product.

[0050] In this embodiment, by using the hybrid material of ABS and PP materials, the performance and quality of the lumbar support cushion are effectively improved, providing a more comfortable and durable product for users.

[0051] Preferably, the soft pad 40 is made of memory foam.

[0052] Specifically, memory foam is a viscoelastic polymer material that can slowly deform and form a depression according to the temperature and pressure of the human body, thereby providing personalized support. Memory foam has the following advantages: Memory foam can slowly deform according to the shape of the human body, and return to its original shape after the pressure is released, providing good support and a sense of wrapping. Memory foam has good breathability and can effectively dissipate heat to keep the cushion dry and comfortable. Memory foam has antibacterial and anti-mite properties, which can effectively inhibit the growth of bacteria and ensure hygienic use. Memory foam is an environmentally friendly material that is non-toxic and odorless and harmless to human health. The memory foam is cut into shapes corresponding to the various parts of the lumbar support cushion body 100. Optionally, the memory foam is fixed to the lumbar support cushion body 100 by hot pressing or bonding. Memory foam of different densities can be selected according to different usage requirements to achieve the best support effect.

[0053] Preferably, the anti-slip portion 50 is provided on the bottom surface of the cushion portion 10 .

[0054] Specifically, the anti-slip portion 50 is a convex block. The anti-slip portion 50 is provided to increase the friction between the waist support cushion and the seat, prevent the cushion from sliding during use, and improve safety and comfort of use.

[0055] Optional implementation methods: anti-slip strips, anti-slip particles, etc.

[0056] Preferably, the waist support cushion body 100 adopts an arc transition, and the waist support cushion is "L"-shaped as a whole.

[0057] The various parts of the lumbar support cushion 100 are designed with smooth arc transitions to avoid sharp edges, improve the comfort of the cushion, and reduce friction and irritation to the human body. The arc transition design can better fit the waist and back curves of the human body and provide more comfortable support. The arc transition design makes the appearance of the lumbar support cushion smoother and rounder, and improves the overall aesthetics of the product. The lumbar support cushion is "L"-shaped as a whole, that is, the seat cushion part 10 and the backrest part 30 are connected at right angles. The "L"-shaped design can provide more stable support for the waist and effectively relieve waist fatigue. The "L"-shaped design can be used as a lumbar support cushion or as a seat cushion, and is highly practical. The radius of the arc can be adjusted according to ergonomic principles to achieve optimal comfort.

[0058] In summary, the utility model provides an innovative lumbar support cushion, which effectively solves the shortcomings of traditional lumbar support products through its integrated design, multi-position support, comfortable materials and other features. Its integrated structure improves the stability of the product, the multi-position support design is ergonomic, and the comfortable cushion material enhances the user experience. The arc-shaped connecting part and the wavy reinforcement ribs enhance the structural strength of the product, and the crescent-shaped through-holes and circular windows improve the ventilation and air permeability. The partition design of the cushion and its adaptation to the shape of the main body enhance the comfort and support of the product, and the "rich"-shaped design makes it more recognizable. The mixed use of ABS and PP materials and the application of memory foam further enhance the performance and quality of the product. The present invention not only has good practicality, but also has a unique appearance design and high market competitiveness.

[0059] The working principle of this utility model is that the seat cushion, connecting portion, and backrest are integrally formed to form a single support structure, which improves the seat cushion's stability and effectively prevents excessive displacement or deformation during use. The curved connecting portion and wavy reinforcement ribs further enhance the seat cushion's structural strength, enabling it to better withstand external pressure. The raised and recessed portions of the seat cushion, as well as the enveloping structure of the backrest, together form a support surface that conforms to the curves of the human waist and back. This multi-point support design effectively distributes pressure on the waist and reduces the burden on the lumbar spine. The soft padding on the seat cushion and backrest enhances comfort by increasing the softness of the contact surface. The use of memory foam slowly deforms according to the body's weight and provides support, further enhancing comfort. The crescent-shaped through-holes in the seat cushion and the circular openings in the backrest facilitate air circulation, reducing stuffiness and keeping the seat cushion dry. The anti-slip treatment on the bottom of the seat cushion increases friction between the seat and the seat, preventing slippage and improving safety.

[0060] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Therefore, any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
