Description

Technical Field

[0001] This utility model relates to a lumbar support seat cushion with an adjustable angle that can be pressed. 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 cushion that supports the lower back by pressing to adjust the angle of the seat cushion and backrest, corrects sitting posture, provides precise support for the lower back, effectively reduces lower back pressure and relieves lower back fatigue, and provides support from three aspects: back, waist and buttocks to ensure stable sitting posture. This invention solves 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 pressing 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 assembly includes an adjustment assembly body, an adjustment button passing through the adjustment assembly body, a button mounting block connected to the adjustment button and located within the adjustment assembly body, a movable block located within the adjustment assembly body, and an adjustment rod connected to the movable block, passing through the adjustment assembly body and matching the adjustment hole. The button mounting block has a sliding groove, and the movable block is connected to a sliding inclined block that matches the sliding groove and moves with the adjustment button, causing the movable block to retract.

[0008] During use, users simply need to press the adjustment button inward, the button mounting block moves inward, the movable block moves outward along the sliding groove, and the adjustment rod retracts and disengages from the adjustment hole, allowing 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. A spring is installed in the spring mounting groove to facilitate the adjustment of the button reset. One side of the spring abuts against the body of the adjustment component.

[0014] The adjustment component body has a button limiting plate on its outer side to limit the adjustment button, so that the adjustment button can only move up and down.

[0015] The lumbar support backrest and seat cushion are respectively connected to the backrest sponge and seat cushion sponge for easy use by fasteners.

[0016] This utility model has the following advantages and beneficial effects:

[0017] This utility model relates to a press-adjustable lumbar support cushion. By pressing, the angle between the cushion and the backrest can be adjusted to suit the physiological angles of different people. Based on individual needs and physical conditions, it can be adjusted to the most suitable angle, providing precise support for the lumbar region, 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 improved work efficiency and quality of life. It is not only suitable for office chairs and car seats, but also for sofas, beds, and other different scenarios, meeting people's needs for lumbar support in various environments.
