[0036] like Figures 1-7 As shown, a preferred embodiment of the lumbar support cushion provided by the present invention includes a seat cushion portion 2, suitable for supporting the buttocks; a backrest base plate 3, connected to the seat cushion portion 2; and a suspended backrest assembly 1, which includes a bracket 12 and a cushion 11 connected to the bracket 12; a fixing assembly 4, one end connected to the bracket 12 and the other end connected to the backrest base plate 3, suitable for fixing the suspended backrest assembly 1 at different positions on the backrest base plate 3; a first guide slide portion 31 is provided on the backrest base plate 3, and a second guide slide portion 121 is provided on the bracket 12, which cooperates with the first guide slide portion 31 to allow the bracket 12 to slide connected to the backrest base plate 3. This embodiment is described using the example of the fixing assembly fixing the adjustable cushion 11 at different positions in the height direction.

[0037] Specifically, the seat cushion 2 includes a base plate, and preferably also includes a soft seat cushion disposed on the base plate, the surface of which has a curved surface that conforms to the curves of the human body.

[0038] The backrest base plate 3 is connected to the rear end of the seat cushion and is set at an angle to the seat cushion part 2, preferably 90 degrees.

[0039] The suspension backrest assembly 1 is preferably provided with a plurality of back cushions 11, which are sequentially arranged on the support 12 and connected to the backrest base plate 3 on the side opposite to the backrest base plate 3, so that the plurality of back cushions 11 are suspended on the backrest base plate 3. Further, the plurality of back cushions 11 are arranged on the support 12 in the horizontal direction, and the height position of the support 12 is adjusted, so that the plurality of back cushions 11 are adjusted in linkage, and the positions of all the back cushions 11 can be quickly adjusted without adjusting the positions of the back cushions 11 one by one, thereby simplifying the adjustment operation, improving the operation efficiency, and optimizing the use experience of the product.

[0040] The fixing assembly 4 includes a fixing piece 41 connected to the support 12, which is provided with a limiting portion 411 and an operating portion 412; and a locking portion 42 provided with a plurality of positioning grooves or positioning teeth and arranged on the backrest base plate 3 in the sliding direction of the suspension backrest assembly 1; and the operating portion 412 can drive the limiting portion 411 to be clamped into or separated from the locking portion 42.

[0041] The fixing piece 41 is connected to the support 12 by penetrating the locking portion 42; the fixing piece 41 is threadedly connected to the backrest base plate 3, and the limiting portion 411 can be clamped into or separated from the locking portion 42 by screwing the fixing piece 41, or the fixing piece 41 is hingedly connected to the support 12, and the limiting portion 411 can be clamped into or separated from the locking portion 42 by turning the fixing piece 41.

[0042] In the embodiment, the fixing piece 41 is threadedly connected to the backrest base plate 3, and the locking portion 42 is provided with five positioning grooves arranged in the vertical direction on the backrest base plate 3, which are sequentially communicated, so that the fixing piece 41 can slide in the locking portion 42, and the sliding direction of the fixing piece 41 is consistent with the sliding direction of the first guide sliding portion 31 on the second guide sliding portion 121. The operating portion 412 is arranged at the end of the fixing piece 41 away from the backrest base plate 3, and is preferably a knob handle; and the limiting portion 411 is arranged on the fixing piece 41 and located on the inner side of the operating portion 412. When the limiting portion 411 is separated from the positioning grooves by screwing the operating portion 412, the back cushion 11, the support 12 and the fixing piece 41 are moved up and down together to adjust the position, and after being adjusted to the desired position, the operating portion 412 is screwed to drive the limiting portion 411 to be clamped into the positioning grooves of the locking portion 42, so as to fix the height position of the back cushion 11.

[0043] As a simple alternative, in some embodiments, the cooperation between the limiting portion 411 and the locking portion 42 can be replaced by the tooth engagement instead of the groove block clamping cooperation.

[0044] In some embodiments, the bracket 12 extends with a protrusion that passes through the locking part 42. The fixing member 41 is hinged to the protrusion, and the limiting part 411 is on the fixing member 41 at the end away from the protrusion. The locking part 42 consists of positioning teeth distributed vertically on the backrest base plate 3. By flipping the fixing member 41, the limiting part 411 is driven into or out of the positioning teeth. Furthermore, a ball head can be provided at the hinge end of the fixing member 41 to further lock and position the bracket 12.

[0045] Furthermore, a first guide slide 31 is provided on the backrest base plate 3, and a second guide slide 121 is provided on the bracket 12. In conjunction with the first guide slide 31, the bracket 12 is slidably connected to the backrest base plate 3. One of the purposes of this arrangement is to make the lifting and lowering adjustment of the suspended backrest assembly 1 smoother and more stable.

[0046] Furthermore, a third guide slide 122 is provided on the bracket 12, located on the side close to the backrest base plate 3; a fourth guide slide 33 is provided on the backrest base plate 3, located on the locking part 42; the third guide slide 122 is slidably connected to the fourth guide slide 33, and the sliding direction is consistent with the sliding direction of the bracket 12 along the second guide slide 121.

[0047] In this embodiment, a first guide slide 31 is provided on each of the two sides of the backrest base plate 3. It is a slide groove or slide rail distributed in the vertical direction, thereby adjusting the height position of the suspended backrest assembly 1. A second guide slide 121 extends from both ends of the bracket 12 toward the backrest base plate 3, so that the bracket 12 is generally n-shaped. The second guide slide 121 is accommodated in the first guide slide 31 and can slide in the first guide slide 31. A third guide slide 122 protrudes from the middle of the bracket 12 toward the backrest base plate 3.

[0048] Furthermore, the backrest 11 is connected to the bracket 12 via the connecting seat 13. An elastic element and a mounting sleeve 14 are provided between the backrest 11 and the connecting seat 13. The mounting sleeve 14 is fitted on the outside of the elastic element. One of the purposes is to increase the dimension of the backrest 11's movable direction, so that it fits the curve of the human back better, and optimizes the comfort and product effect.

[0049] Furthermore, a handle 32 is provided on the backrest base plate 3, which is suitable for holding the lumbar support cushion and provides convenience for moving or carrying. Preferably, the handle 32 is a through hole provided on the top of the backrest base plate 3.

[0050] This utility model discloses a lumbar support cushion that features a suspended backrest assembly. The backrest assembly is fixed to different positions on the backrest base plate by a fixing assembly, and is guided by a second guide slide on the bracket and a first guide slide on the backrest base plate, thereby making the position adjustment of the suspended backrest assembly smoother and more stable.

[0051] The above embodiments only illustrate a portion of the implementation methods of the present invention.
