[0002] Posture cushions belong to the field of ergonomic support equipment. They appear in the form of legless chairs and their function is to improve sitting comfort. In recent years, the structure of this type of product has continued to evolve, and composite designs integrating back support and lumbar support have gradually emerged. Some products use shape and mechanical structure to achieve auxiliary correction of sitting posture.

[0003] However, most existing seat cushions use traditional materials such as flexible foam and memory foam, whose inherent heat insulation properties result in poor heat dissipation. When users sit for extended periods, localized heat buildup and sweat retention can easily occur, severely impacting comfort and health.

[0047] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0048] A suspended lumbar support cushion includes a backrest portion 1 and a seat cushion portion 2. The backrest portion 1 includes a backrest support frame 11 and a backrest mesh surface 12, with the backrest mesh surface 12 connected to the backrest support frame 11 via its edge. The seat cushion portion 2 includes a seat cushion support frame 21 and a seat cushion mesh surface 22, with the seat cushion mesh surface 22 connected to the seat cushion support frame 21 via its edge. The backrest support frame 11 is rotatably connected to the seat cushion support frame 21, thereby allowing the lumbar support cushion to have a usage state where the backrest portion 1 and the seat cushion portion 2 form an angle, and a storage state where the backrest portion 1 and the seat cushion portion 2 are close together. By providing breathable mesh surfaces for the seat cushion portion 2 and the backrest portion 1 respectively, the heat dissipation and air circulation effect are significantly improved. At the same time, the backrest portion 1 and the seat cushion portion 2 are rotatably connected, allowing the lumbar support cushion to flexibly switch between the usage state and the folded storage state, greatly improving the convenience of use and storage.

[0049] Specifically, the backrest mesh 12 and the seat mesh 22 can be fully tensioned and laid on the backrest support 11 and the seat support 21 respectively; or they can be laid with less tension, or even simply hung on the support. In actual production, they can be adapted to different usage positions without affecting the breathability and heat dissipation properties of this lumbar support seat cushion.

[0050] The lower end of the backrest 1 is rotatably connected to the upper rear end of the seat cushion 2; alternatively, the lower end of the backrest 1 can be connected to the rear end of the seat cushion 2, or the lower end of the backrest 1 can be connected to the middle and rear part of the seat cushion 2, or the rear end of the seat cushion 2 can be connected to the lower middle part of the backrest 1; these can be adjusted according to the actual style and appearance.

[0051] In the following first embodiment, an example is given where both mesh surfaces are taut and covered, and the lower end of the cushion part 1 is rotatably connected to the upper rear side of the seat cushion part 2.

[0052] Example 1

[0053] like Figures 1-13 The image shows a preferred embodiment of a suspended lumbar support cushion provided by the present invention.

[0054] The seat cushion 1 also includes a heat dissipation chamber 23.

[0055] The seat support 21 includes a base plate 211 and a lift frame 212. The lift frame 212 is distributed circumferentially along the edge of the base plate 211 and is located on the side close to the backrest part 1. The seat mesh surface 22 is connected to the upper end of the lift frame 212, and the base plate 211 is connected to the lower end of the lift frame 212.

[0056] The base plate 211, the raised frame 212, and the seat cushion mesh 22 together form a heat dissipation chamber 23.

[0057] The seat cushion mesh 22 is suspended by the cantilever frame 212, and a heat dissipation chamber 23 is formed below the mesh, which significantly improves the heat dissipation and air circulation of the seat cushion 2.

[0058] In use, the lower end face of the base plate 211 contacts the seat surface or the ground, etc.; the lift frame 212 is located on one side of the upper end face of the base plate 211. The lift frame 212 is preferably a ring-shaped protrusion structure formed by continuous protrusions, and forms an upward-opening container shape with the base plate 211; in some other embodiments, the lift frame 212 may also be a ring-shaped protrusion strip structure formed by discontinuous but ring-shaped protrusions distributed on the edge of the base plate 211.

[0059] Preferably, the seat cushion mesh 22 is tautly laid on the upper end of the raised frame 212, and the heat dissipation chamber 23 is located below the seat cushion mesh 22, thereby improving the breathability and heat dissipation effect of this lumbar support seat cushion and reducing the unpleasant experience caused by stuffiness due to the seat cushion.

[0060] The way the seat cushion mesh 22 is connected to the seat cushion bracket 21 and the way the backrest mesh 12 is connected to the backrest bracket 11 can be by nail gun, adhesive, or sewing. Any of the methods used to fix leather surfaces in the basic furniture industry can be adopted.

[0061] It should be noted that the "floating" in this article mainly refers to a unique experience obtained by the user when sitting on this cushion, which is achieved by the following structure: First, both the seat cushion mesh 22 and the backrest mesh 11 are made of highly elastic materials and are tensioned and fixed around the perimeter, forming a support surface that can elastically sink in the central area. When the user sits down, the mesh surface will sink appropriately to conform to the curve of the human body, while providing a uniform upward lifting force. This soft support is different from the sinking feeling of hard seats or soft foam, giving people a floating feeling of the buttocks and waist being gently "lifted"; furthermore, the heat dissipation chamber 23 set in the seat cushion 2 forms a cavity structure with an open bottom. When viewed from the side and rear, there is a clear gap between the seat cushion mesh 22 and the placement surface, such as the chair surface, as if the seat surface is "floating" on the base, creating a unique visual floating feeling.

[0062] Furthermore, the base plate 211 includes a supporting portion 2111 and a curved portion 2112; the curved portion 2112 extends backward and then upward from the rear end of the supporting portion 2111; the cushion bracket 11 connects to the curved portion 2112. In this embodiment, the two extensions of the curved portion 2112 preferably form a smoothly transitioning arc surface, so that the arc surface forms a rear-convex arc surface, thereby enhancing the structural strength of the curved portion 2112.

[0063] It should be noted that the rear end of the support part 2111 here refers to the end furthest from the user's legs, with the user sitting on the cushion and the direction of the user's own orientation as the standard for front, back, left and right.

[0064] Furthermore, such as Figure 12 , 13 As shown, the cross-section along the horizontal plane at the height position of the middle section of the curved surface 2112 has a backward-convex arc shape; the cross-section along the vertical plane at the width position of the middle section of the curved surface 2112 has a backward-convex smooth arc shape.

[0065] It should be noted that the mid-section height position refers to a small vertical displacement of the curved surface 2112 along its height direction; similarly, the mid-section width position refers to a small horizontal displacement of the curved surface 2112 along its width direction. In this embodiment, Figure 12 It is a cross-sectional view along the horizontal plane at the midpoint of the curved surface in the height direction of 2112. Figure 13 It is a cross-sectional view along the vertical plane at the midpoint of the width direction of the curved surface 2112.

[0066] This can be understood as follows: the arcs on the same horizontal plane of the curved surface 2112 are located on the same circle or nearly on the same circle; while the smooth arcs on the vertical surface are formed by the smooth transition between the two smooth arcs as the curved surface 2112 extends backward and then upward. The purpose of setting the curved surface 2112 in this shape is to strengthen the structural strength while improving the appearance.

[0067] Furthermore, such as Figure 13 As shown, the smooth arc of the vertical section includes a first arc and a second arc. The first arc is located on the side near the support part 2111, and the second arc is located on the side near the backrest part 1. The curvature of the first arc is less than the curvature of the second arc, so that the end of the curved surface 2112 near the backrest part 1 is more curved than the end near the seat cushion part 2, thereby further strengthening the structural strength of the product.

[0068] Furthermore, the cantilever frame 212 is at least partially connected to the curved surface 2112. One purpose of this is to increase structural strength and reduce the possibility of fracture or material fatigue of the base plate 211 at the rear end of the cantilever frame 212, especially when the connection between the cantilever frame 212 and the base plate 211 is made using an integral molding process.

[0069] The cantilever frame 212 includes a main frame 2121 and a sub-frame 2122. The main frame 2121 is distributed circumferentially at the edge of the base plate 211. An assembly groove 2123 is provided at the rear end of the main frame 2121. The sub-frame 2122 is connected to the assembly groove 2123, thereby forming a complete cantilever frame 212.

[0070] In this embodiment, the main frame portion 2121 of the cantilever frame 212 is integrally formed with the base plate 211. The separate sub-frame portion 2122, comprising a small portion of the cantilever frame 212, is designed for ease of demolding during production. In other embodiments, the cantilever frame 212 may not be divided into the main frame portion 2121 and the sub-frame portion 2122; instead, it may be a single, integral unit, fixed to the base plate 211 via bonding, ultrasonic welding, screw connections, or other methods.

[0071] Furthermore, a limiting groove 21231 is provided on the bottom surface of the assembly groove 2123, and a limiting strip 21221 that can be engaged with the limiting groove 21231 is provided at the lower end of the sub-frame 2122, which facilitates positioning and installation and reduces the occurrence of shaking of the sub-frame 2122. As a simple technical alternative, the positions of the limiting groove 21231 and the limiting block can be interchanged, that is, the limiting strip 21221 is provided at the bottom of the assembly groove 2123, and the limiting groove 21231 is provided at the lower end of the sub-frame 2122.

[0072] It also includes a first pressing frame 3; an annular first assembly groove is provided on the outer side wall of the cantilever frame 212, and the seat cushion mesh 22 is fixed to the first assembly groove through the first pressing frame 3, so that the seat cushion mesh 22 is tightly covered to the seat cushion bracket 21, forming an elastic support surface and improving the comfort of using the seat cushion.

[0073] Furthermore, the seat cushion mesh 22 after tensioning and assembly has a downward-curving slope on the side away from the backrest part 1. Preferably, the slope is a curved surface with an arc, thereby forming a soft cushioning part to reduce the discomfort caused by squeezing the thighs.

[0074] The cushion support 11 includes an assembly frame 110 and a connecting plate 111 connected to one end of the assembly frame 110; the cushion mesh 12 is laid on the assembly frame 110; the connecting plate 111 is rotatably connected to the seat cushion 2.

[0075] In this embodiment, a hollow 112 is provided in the middle of the assembly frame 110, preferably a complete elliptical or circular hollow 112; the cushion mesh 12 is stretched and laid on the edge of the assembly frame 110.

[0076] Furthermore, such as Figure 7 , 8 As shown, the backrest mesh 12, which is tensioned and installed to the assembly frame 110, has a smooth arc shape that bulges forward along the horizontal plane at the middle height position, and a circular arc shape that bulges forward along the vertical plane at the middle width position, thereby providing better support for the user's lower back.

[0077] It should be noted that the mid-height position here is the same as explained above; it refers to a small vertical displacement of the cushion mesh 12 in its height direction. Similarly, the mid-width position refers to a small horizontal displacement of the cushion mesh 12 in its width direction. In this embodiment, Figure 8 This is a cross-sectional view along the horizontal plane at the midpoint of the height of the cushion mesh 12. Figure 7 This is a cross-sectional view along the vertical plane at the midpoint of the width of the cushion mesh 12.

[0078] Furthermore, the assembly frame 110 includes an annular base plate 116, a first reinforcing ring 113, a second reinforcing ring 114, and a clamping plate 115; the first reinforcing ring 113 and the second reinforcing ring 114 are spaced apart on the rear side of the annular base plate 116; the clamping plate 115 is distributed circumferentially along the annular base plate 116, and the padding mesh surface 12 is connected between the clamping plate 115 and the annular base plate 116; one of the purposes is to optimize the structure, so as to ensure structural strength while taking into account the needs of saving materials and aesthetics.

[0079] Furthermore, an extension plate 117 extends from the lower end of the connecting plate 111; the seat cushion 2 is rotatably connected to the inner side of the connecting plate 111, and the assembled extension plate 117 is located on the outer side of the seat cushion 2. The extension plate 117 increases the contact area between the seat cushion 2 and the backrest 1, shares the pressure at the rotatable connection between the two, and improves the structural strength and service life of the product.

[0080] In this embodiment, the upper end of the rear side of the seat cushion 2 is connected to the lower end of the backrest cushion 1. When in use, the backrest cushion 1 and the seat cushion 2 are set at an angle, forming the shape of a chair seat. When in storage, the backrest cushion 1 is close to the seat cushion 2, compressing the space occupied by this lumbar support cushion, making it easy to carry or store.

[0081] It also includes a second clamping frame; the clamping plates 115 are distributed circumferentially along the annular base plate 116 and form a second assembly groove with an opening facing outward between them. The cushion mesh 12 is fixed to the second assembly groove by the second clamping frame, so that the cushion mesh 12 is tightly covered with the cushion support 11 to form an elastic support surface and improve the comfort of using the sitting cushion.

[0082] Example 2

[0083] As a variation of the above embodiment, the integral molding of the cantilever frame 212 and the base plate 211 is replaced by a separate and fixedly connected configuration.

[0084] Specifically, the main frame 2121 and the sub-frame 2122 are integrally formed and fixed to the base plate 211 by means of bonding, ultrasonic welding, screw connection and other fixing methods.

[0085] This utility model relates to a suspended lumbar support cushion. By providing breathable mesh surfaces in both the seat and backrest sections, it significantly improves heat dissipation and air circulation. Simultaneously, the backrest and seat sections are connected by a rotating mechanism, allowing the cushion to flexibly switch between its active and folded storage states, offering both ease of use and portability. Furthermore, by resting their backs against the backrest, users can reduce the probability of developing hunchback and nearsightedness due to forward-leaning posture.

[0086] 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.
