[0002] Lumbar support cushions, as a common support and care device, are widely used in daily life and work, especially for prolonged sitting. They effectively relieve lumbar pressure and prevent and reduce lumbar fatigue. The main function of a lumbar support cushion is to provide lumbar support, helping to maintain the natural curve of the spine through reasonable support distribution, and preventing lumbar injuries caused by prolonged sitting or poor posture. Many lumbar support cushions adopt ergonomic designs, providing personalized support according to the user's lumbar curve. These cushions can be adjusted in different ways, such as adjusting firmness, angle, or height, to adapt to different needs. For office workers who sit at desks for long periods, drivers, or those who need to stand for long periods, lumbar support cushions can play a significant role. They not only improve posture and maintain the natural curve of the spine, but also reduce lumbar muscle fatigue, preventing lumbar discomfort or strain.

[0018] Example 1 Different users have different lumbar positions, requiring adaptive adjustments to the lumbar support cushion to accommodate different lumbar curves and support needs in different areas. Therefore, this embodiment proposes an adjustable lumbar support cushion, such as... Figures 1-4 As shown, in order not to affect the display of the internal structure, Figure 4 Spring 13 has been removed. The overall structure is as follows: Figure 1 and Figure 2 As shown, Figure 1 This is a front view. Figure 2 This is a rear view. Specifically, it includes a mounting plate 1, a back support pad 2, a lumbar support pad 4, a sacral support pad 5, and multiple telescopic adjustment components. The lumbar support pad 4 has a curved front.

[0019] like Figure 3 and Figure 4 As shown, multiple telescopic adjustment components are arranged along the central axis of the mounting plate 1 in the height direction, and one end of each component is independently driven to extend or retract. The backs of the back support pad 2 and the waist support pad 4 are engaged with ball joints at one end of the multiple telescopic adjustment components, and the curve state is changed by the extension and retraction of the multiple telescopic adjustment components. The two sides of the backs of the back support pad 2 and the waist support pad 4 are connected to the mounting plate 1 by springs 13. In this embodiment, a screw is used as the adjustment component, but other telescopic components, such as electric telescopic rods, can also be used. This utility model is not limited to this. Figure 3As shown, the telescopic adjustment assembly includes a support plate 11, an adjusting screw 7, and an adjusting nut 6. One end of the support plate 11 is fixedly mounted on the back of the back support pad 2 or the lumbar support pad 4. The adjusting screw 7 passes through the support plate 11 and is threadedly engaged with it. One end of the adjusting screw 7 is fixed with a ball joint 12, which engages with the support plate 11. The adjusting nut 6 is fixedly connected to the other end of the adjusting screw 7. During adjustment, rotating the adjusting nut 6 causes the adjusting screw 7 to rotate and move. Due to the ball joint 12, there is no resistance to rotation, and the added spring limit ensures that the back support pad 2 and the lumbar support pad 4 are in a stable support state. The movement of the adjusting screw 7 pushes the support plate 111, causing the side curve of the back support pad 2 or the lumbar support pad 4 to change. This allows for fine-tuning according to the user's actual curve, achieving a perfect curve fit and support. Furthermore, in order to make the mounting plate 1 a complete plate surface without protrusions, this utility model provides an elongated groove on the back of the mounting plate 1, and the ends of the adjusting nut 6 and the adjusting screw 7 both fall into the elongated groove.

[0020] like Figure 3 and Figure 4 As shown, the sacral support pad 5 is rotatably mounted on the mounting plate 1 via a rotation drive, and is located below the lumbar support pad 4. The support angle is adjusted by the rotation drive. Specifically, the rotation drive includes a rotating shaft 8, a rotating plate 9, and two support plates 10; the mounting plate 1 has a groove; one end of each of the two support plates 10 is detachably and fixedly connected to both sides of one end of the rotating plate 9 via snap fasteners, and the other end is fixedly connected to the back of the sacral support pad 5; the rotating shaft 8 passes through the other end of the rotating plate 9 and is fixedly connected to the rotating plate 9; a second motor is fixedly mounted at one end of the groove; both ends of the rotating shaft 8 are fixedly connected to the other end of the groove and are drively connected to the output shaft of the second motor. This embodiment uses a motor drive; however, the specific implementation can also use a ratchet, screw, or other manually adjustable structure, which is not limited here.

[0021] For individuals with weaker muscles on both sides of the lower back, this invention also includes symmetrically arranged side support components on both sides of the lower back support pad 4, such as... Figure 3 As shown, the lumbar support assembly includes a first motor and a lumbar support pad 3. The first motor is embedded in the bottom of the back support pad 2 and located on one side of the lumbar support pad 4. The top of the lumbar support pad 3 is connected to the output shaft of the first motor. This embodiment uses a motor drive to drive the lumbar support pad 3 to swing, achieving effective support. Of course, the specific implementation can also be a manually adjustable structure such as a ratchet or screw, which is not limited here.

[0022] In addition, the back support pad 2, the side lumbar support pad 3, the lumbar support pad 4, and the sacral support pad 5 are all fabric memory foam frames with zippers, filled with memory foam, making them easy to clean, disassemble, and replace.

[0023] In this embodiment, the backrest cushion comprehensively considers the support needs of the back, waist, and sacrum, and is meticulously designed and integrated with multiple telescopic adjustment components and a spring-loaded cushioning support system. Through the combination of these technologies, the backrest cushion allows for multi-curve free adjustment of the back support pad 2 and the waist support pad 4. Users can adjust the shape and angle of the cushion according to different usage scenarios and personal needs, especially adapting to the different lumbar conditions of various users. For example, for users who sit for long periods or experience lower back discomfort, the cushion can provide a customized support solution, ensuring that users maintain a comfortable and healthy lumbar curve in different postures, thereby greatly reducing pressure and fatigue in the lower back.

[0024] In addition, the cushion features a specially designed sacral support pad 5. This component can be disassembled and connected via a rotating drive mechanism, and flexibly installed on the cushion's mounting plate 1. This design allows users to adjust the strength and position of the sacral support according to their needs, ensuring that the sacrum receives adequate support. Whether a user requires enhanced sacral support or has lower requirements for sacral support, adjusting this component can achieve the best support effect, further enhancing comfort and adaptability.

[0025] The entire cushion's shape is designed strictly according to ergonomic principles, with a particular focus on the precise curves of the human lumbar region. From the upper back extension area to the middle lumbar support area and the lower sacral support area, each section has been meticulously fine-tuned to ensure a perfect fit to the human waist. Regardless of the user's body type, the cushion provides perfect back, lumbar, and sacral support through precise adjustments, achieving a comprehensive comfort and precise support experience.

[0026] To further enhance user comfort and support, this cushion also features two lumbar support components. These components provide customized support based on the specific needs of the user's lower back, effectively reducing pressure on the sides of the lower back and lowering the risk of strain and discomfort, especially for users with weaker lower back muscles or those frequently experiencing strain. Through these innovative designs, this cushion provides comprehensive, three-dimensional support, greatly improving user health and reducing the occurrence of lower back strain.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
