In other embodiments, the outer support plate 120 may also be an annular wall formed by multiple spaced-apart plates. The inner support plates 121 are preferably a pair, with their two ends connected to the inner sides of the front and rear ends of the annular outer support plate 120, respectively, to increase the structural strength of the suspended support 12.

[0046] Furthermore, the suspended bracket 12 is slidably connected to the base plate 13, and the two can be detached and assembled.

[0047] A plurality of latches 122 are provided on the lower side of the suspended bracket 12. The latches 122 form a sliding groove that can engage with the edge of the substrate 13. One purpose is to allow the pad surface 11 and the suspended bracket 12 as a whole to be detached from the substrate 13 for easy cleaning and replacement.

[0048] In this embodiment, a latch 122 is provided on the left side, the right side, and the side away from the backrest 2 of the suspended bracket 12.

[0049] The latch 122 extends downward from the lower end of the suspended bracket 12 and then towards the center of the seat cushion, forming an L-shaped shape. Therefore, the latch 122 includes a base plate and a side plate. The upper end of the side plate is connected to the suspended bracket 12, and the lower end is connected to the base plate. A groove is formed between the lower end of the suspended bracket 12 and the base plate of the three latches 122. By sliding the base plate 13 into or out of the groove, the suspended bracket 12 can be installed on or removed from the base plate 13.

[0050] In some other embodiments, as a simple alternative, the latch 122 can be provided on the base plate 13, and a sliding groove corresponding to the shape of the base plate is preset on the outer side wall of the suspended bracket 12, so that the base plate acts as a guide slider to realize the sliding connection between the base plate 13 and the suspended bracket 12.

[0051] To further secure the suspended bracket 12, a plurality of mounting holes 131 are provided on the base plate 13; a plurality of mounting posts 124 are provided on the suspended bracket 12, the shape of which is adapted to the mounting holes 131; and an assembly 16 is also included, wherein the mounting posts 124 pass through the mounting holes 131 and are fixedly connected to the assembly 16.

[0052] In this embodiment, an elliptical mounting hole 131 is provided on both sides of the substrate 13; correspondingly, the mounting post 124 is elliptical cylindrical and is provided at the lower end of the inner support plate 121; the mounting part 16 is fixed to the mounting post 124 by screws, and the shape of the mounting part 16 is larger than the mounting hole 131, so that it can cooperate with the mounting post 124 to better fix the suspended bracket 12 to the substrate 13.

[0053] In this embodiment, preferably, the upper end of the substrate 13 has a downwardly recessed arc-shaped surface, and an annular recessed ladder is provided on the arc-shaped surface. Its shape is adapted to the bottom end of the suspended bracket 12, providing a limit for the suspended bracket 12 and providing convenient positioning between the fixed assembly column 124 and the assembly hole 131 during installation.

[0054] The cushion surface 11 includes a pressing frame 112 and a flexible fabric or flexible mesh surface 111; the flexible fabric or flexible mesh surface 111 is stretched and covered by the pressing frame 112 to form an elastic support surface, which improves the comfort of using the sitting cushion.

[0055] In this embodiment, a flexible mesh surface 111 is preferably used, and the aforementioned first ventilation hole 114 is a mesh distributed on the flexible mesh surface 111. When a flexible fabric surface is selected, the first ventilation hole 114 is a fabric hole distributed on the flexible fabric surface.

[0056] Furthermore, the side of the cushion 11 away from the backrest 2 has a downwardly curved slope 113, preferably a curved surface with an arc; it also includes a cushioning block 15, connected to the end of the suspension bracket 12 away from the backrest 2, located below the slope 113, and the cushioning block 15 is preferably made of a soft material. One purpose is to form a soft cushioning area under the user's legs to reduce discomfort caused by pressure on the thighs.

[0057] Furthermore, it also includes a limiting strip 123, with both ends of the limiting strip 123 connected to the suspended bracket 12 respectively; the limiting strip 123 and the side of the suspended bracket 12 away from the backrest 2 are enclosed with the inner side of the outer support plate 120 of the suspended bracket 12 to form an assembly groove 125 suitable for installing the buffer block 15.

[0058] A second vent hole 132 is provided on the substrate 13 and communicates with the cavity 14. In this embodiment, it is preferable to set the second vent hole 132 at the center of the substrate 13, and its shape is the same as that of the mounting hole 131, so as to improve the efficiency of research and development and production. Example

[0059] As a variation of the above embodiment, the suspended bracket 12 is integrally formed with the substrate 13, the suspended bracket 12 extends from the substrate 13 toward the pad surface 11, and at least a portion of the cavity 14 is provided in the suspended bracket 12.

[0060] Specifically, a suspended support 12 extends from the substrate 13 toward the pad surface 11; the pad surface 11 is connected to the top of the suspended support 12 via a clamping frame 112; on the substrate 13, the part surrounded by the suspended support 12 is hollowed out, and the cavity 14 is formed by the pad surface 11 and the suspended support 12. The cavity 14 extends from the bottom surface of the pad surface 11, through the suspended support 12, to the bottom surface of the substrate 13, and is an inverted semi-open chamber.

[0061] This invention relates to a suspended lumbar support cushion. A cavity is created in the cushion's seat area, and a first ventilation hole is provided on the cushion surface, communicating with the cavity. This creates a ventilation chamber beneath the cushion surface, accelerating heat dissipation and ventilation. Furthermore, by resting their back against the backrest of this cushion, users can reduce the probability of developing hunchback and nearsightedness due to forward-leaning posture.

[0062] The above embodiments only illustrate a portion of the implementation methods of the present invention. Any modifications, substitutions, and improvements made by those skilled in the art without departing from the inventive concept of the present invention, without creative effort, are all within the protection scope of the present invention.
