Description

Technical Field

[0001] This utility model relates to a lumbar support seat cushion with adjustable angle that slides left and right. It belongs to the technical field of lumbar support seat cushions. Background Technology

[0002] Seat cushions are an indispensable part of our daily lives. With the widespread use of computers, office workers spend long hours in front of them. Prolonged sitting not only causes fatigue but can also damage the spine, lumbar vertebrae, and sciatic nerve, potentially leading to hemorrhoids, prostate problems, and other ailments. Ordinary seat cushions have a simple structure and lack lumbar support, failing to effectively alleviate these symptoms. Furthermore, using separate seat and lumbar cushions can lead to misalignment and slippage. Additionally, most seat cushions on the market are one-piece structures with no ventilation or breathability between the backrest and seat. Prolonged sitting prevents the evaporation of sweat, causing discomfort, especially in summer. Utility Model Content

[0003] This invention proposes a lumbar support seat cushion that allows for adjustment of the seat and backrest angles by moving left and right together, thereby supporting the lower back and providing precise support to the lower back at the most suitable angle. This effectively reduces lower back pressure and alleviates lower back fatigue, solving the problems existing in the prior art.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0005] A lumbar support seat cushion with adjustable angle by sliding left and right includes a seat cushion and a lumbar support backrest hinged to the seat cushion and movable relative to the seat cushion. Two backrest mounting blocks are installed on the back of the seat cushion, and the lumbar support backrest is equipped with an adjustment component that matches the backrest mounting blocks and is installed between the two backrest mounting blocks.

[0006] The backrest mounting block has multiple adjustment holes; the number of adjustment holes is set to two or more.

[0007] The adjustment component includes an adjustment component body, a left and right sliding button that passes through the adjustment component body and can move inward, a button mounting block connected to the left and right sliding button and located inside the adjustment component body, and an adjustment rod connected to the button mounting block and passing through the adjustment component body and matching the adjustment hole. A spring for easy reset is provided between the two button mounting blocks.

[0008] During use, users simply slide the left and right sliding buttons inwards, causing the button mounting block to move inwards and the adjustment rod to move out of the adjustment hole. This allows the adjustment rod to be inserted into another adjustment hole to adjust the angle of the seat cushion and lumbar support backrest.

[0009] Two support rods extend from the lower part of the adjustment component body. The support rods are L-shaped, including a vertical end and a horizontal end. The horizontal end of the support rod extends into a protruding limiting block to provide support and installation. The protruding limiting block is installed on the seat cushion. During installation, only the support rods and adjustment buttons need to be installed to install the adjustment component into the seat cushion and lumbar support backrest.

[0010] The lumbar support backrest has a rotating support foot extending below it. The rotating support foot extends into the rotating rod through a limiting tube to facilitate the limited rotation of the seat cushion and the lumbar support backrest. The rotating rod is installed on the seat cushion.

[0011] The backrest mounting block has a first inner limiting step installed on its inner side, and the adjustment component body has a second inner limiting step installed on its outer side that matches the first inner limiting step, so as to facilitate the precise and smooth installation of the adjustment component and the backrest mounting block.

[0012] An inner step matching the adjusting rod is installed on the outside of the adjusting hole to facilitate the insertion and support of the adjusting rod.

[0013] A spring mounting groove is provided on one side of the button mounting block, and the spring is installed in the spring mounting groove.

[0014] The lumbar support backrest and seat cushion are respectively connected to the backrest sponge and seat cushion sponge for easy use by fasteners.

[0015] This utility model has the following advantages and beneficial effects:

[0016] This utility model relates to a sliding, adjustable lumbar support cushion. By pressing, the angle between the cushion and backrest is adjusted to suit the physiological needs of different individuals. Based on individual needs and physical condition, it can be adjusted to the most suitable angle, providing precise lumbar support, effectively reducing lumbar pressure and relieving lumbar fatigue. It is especially suitable for people who sit for long periods or have lumbar problems. It also helps users maintain correct posture, avoiding lumbar pain and spinal deformities caused by poor posture. By adjusting the angle, the lumbar region is positioned in its natural physiological curve, reducing damage to the lumbar spine. The adjustable angle design better conforms to the human lumbar curve, providing comfortable support whether working, studying, or resting, improving physical comfort and contributing to increased work efficiency and quality of life. It is not only suitable for office chairs and car seats, but also for sofas, beds, and other scenarios, meeting people's needs for lumbar support in various environments. Attached Figure Description
