Detailed Description
For a further understanding of the present invention, reference will be made to the following detailed description of the invention, taken in conjunction with the accompanying drawings 1-2.
With reference to fig. 1-2, the seat cushion with a lumbar support of the present embodiment includes a seat cushion 4 and a backrest 1, and the seat cushion 4 is hinged to the backrest 1. The seat cushion 4 is provided with a first hinge part, the backrest 1 is provided with a second hinge part, and the first hinge part and the second hinge part are rotatably connected through a pin shaft. The backrest 1 is provided with a waist rest 2, and the waist rest 2 is detachably connected with the backrest 1. A gear structure for adjusting the height of the lumbar support 2 is arranged between the lumbar support 2 and the backrest 1. The gear structure comprises a screw, a limiting part 11 arranged on the backrest 1 and a connecting part 2 arranged on the waist rest 2. The limiting part 11 is provided with a connecting hole 12, and the head of the screw is limited to the limiting part 11 when the screw passes through the connecting hole 12 and is in threaded connection with the connecting part 21. When the waist support is used specifically, the limiting part 11 is a limiting concave part, the screw head can be arranged in the limiting concave part, and the limiting screw cannot move up and down so as to fix the height of the waist support 2. In another embodiment, the limiting portion 11 is a limiting block protrusion, and a plurality of limiting block protrusions surround the screw head so that the screw head cannot move up and down to fix the height of the lumbar support 2. The connecting holes 12 are longitudinally arranged long holes, and the limiting concave parts are provided with a plurality of limiting concave parts which are distributed on the left side and the right side of the long holes. The limiting concave parts are linearly and uniformly distributed on the side parts of the strip holes, and the distances between the upper limiting concave part and the lower limiting concave part are consistent, so that the waist rest 2 can adjust different height gears.
