[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.

[0049] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0050] A suspended seat cushion includes a backrest portion 2 and a seat cushion portion 1 connected to the backrest portion 2. The seat cushion portion 1 includes a seat cushion support 11, a seat cushion mesh surface 12, and a heat dissipation chamber 13. The seat cushion mesh surface 12 is connected to the seat cushion support 11. The seat cushion support 11 includes a base plate 111 and a raised frame 112. The raised frame 112 includes at least two side frame plates 1121, connecting the two sides of the base plate 111. The seat cushion mesh surface 12 is connected to the upper end of the raised frame 112, and the base plate 111 is connected to the lower end of the raised frame 112. The base plate 111, the raised frame 112, and the seat cushion mesh surface 12 together form the heat dissipation chamber 13. By suspending the seat cushion mesh surface 12 through the raised frame 112 and forming the heat dissipation chamber 13 below the mesh surface, the heat dissipation and air circulation of the seat cushion portion 1 are significantly improved.

[0051] It should be noted that "suspension" refers to the seating feel. Specifically, the seat cushion mesh 12 is supported by the raised frame 112, forming a cavity between it and the base plate 111, giving the rider a light and transparent visual and physical effect.

[0052] Specifically, the seat cushion mesh 12 can be fully tensioned and laid on the cantilever frame 112 respectively; it can also be laid with less tension, or even simply hung on the frame; in actual production, it can be adapted to different usage positions without affecting the breathability and heat dissipation properties of the seat cushion 1.

[0053] The lower end of the backrest 2 is connected to the upper rear end of the seat cushion 1; alternatively, the lower end of the backrest 2 can be connected to the rear end of the seat cushion 1, or the lower end of the backrest 2 can be connected to the middle and rear part of the seat cushion 1, or the rear end of the seat cushion 1 can be connected to the lower middle part of the backrest 2; these can be adjusted according to the actual style and appearance.

[0054] In the following first embodiment, the example is illustrated by the seat cushion mesh 12 being tightly laid and the lower end of the backrest part 2 being rotatably connected to the upper rear side of the seat cushion part 1.

[0055] Example 1

[0056] like Figure 1-14 The image shows a preferred embodiment of a suspended seat cushion provided by the present invention.

[0057] A floating seat cushion includes a backrest portion 2 and a seat portion 1. The backrest portion 2 includes a backrest support 21 and a backrest mesh surface 22, with the backrest mesh surface 22 connected to the backrest support 21 through its edge. The backrest support 21 is rotatably connected to the seat support 11, so that the floating seat cushion can have a usage state in which the backrest portion 2 and the seat portion 1 form an angle, and a storage state in which the backrest portion 2 and the seat portion 1 are close together. The floating seat cushion can flexibly switch between the usage state and the folded storage state, greatly improving the convenience of use and storage.

[0058] The cushion mesh 22 can be fully tensioned and laid separately on the cushion support 21; it can also be laid with less tension, or even simply hung on the support; in actual production, it can be adapted to different usage positions without affecting the breathability and heat dissipation properties of this suspended cushion.

[0059] The way the seat cushion mesh 12 is connected to the seat cushion bracket 11 and the way the backrest mesh 22 is connected to the backrest bracket 21 can be by nail gun fixing, by adhesive fixing, or by sewing fixing. Any of the fixing methods used for leather products in the basic furniture field can be adopted.

[0060] In use, the lower end face of the base plate 111 contacts the seat surface or the ground, etc.; the lift frame 112 is located on one side of the upper end face of the base plate 111. The lift frame 112 is preferably a ring-shaped protrusion structure formed by continuous protrusions, and forms an upward-opening container shape with the base plate 111; in some other embodiments, the lift frame 112 may also be a ring-shaped protrusion strip structure formed by discontinuous but ring-shaped protrusions distributed on the edge of the base plate 111.

[0061] Furthermore, the height of the side frame 1121 gradually increases and then decreases from the front end to the rear end, so that the top surface of the side frame 1121 presents a smooth arc surface with a central convex shape; the highest point of the side frame 1121 is located on the side closer to the front end. One purpose is to enable the seat cushion mesh 12 to provide a curved surface that better conforms to the human body structure. Since the highest point of the side frame 1121 is located on the side closer to the front end, that is, the side closer to the lower leg, it can better support the legs, and the user is less likely to slip off the seat cushion, thus optimizing the product user experience.

[0062] It should be noted that the front and rear ends of the side panel 1121 refer to the front, back, left, and right directions relative to the user's own orientation when the user is sitting on the cushion. The front end is the end closer to the legs, and the rear end is the end furthest from the user's legs.

[0063] Furthermore, the cantilever frame 112 also includes a front frame plate 1122 and / or a rear frame plate 1123; the two ends of the front frame plate 1122 are respectively connected to a side frame plate 1121; the two ends of the rear frame plate 1123 are respectively connected to a side frame plate 1121. For example, the cantilever frame 112 includes a left frame plate 1121, a front frame plate 1122, and a right frame plate 1121, or for example, the cantilever frame 112 includes a left frame plate 1121, a rear frame plate 1123, and a right frame plate 1121. For example, in this embodiment, the cantilever frame 112 includes a left frame plate 1121, a front frame plate 1122, a right frame plate 1121, and a rear frame plate 1123.

[0064] The front frame plate 1122, one side frame plate 1121, the rear frame plate 1123, and the other side frame plate 1121 are connected end to end in sequence, and the four of them surround the base plate 111, so that the seat cushion support 11 forms a basin-shaped container structure. One of the purposes is that the overall basin-shaped seat cushion support 11 can further improve the structural strength of the seat cushion support 11, and at the same time, it can cleverly form a heat dissipation chamber 13 under the seat cushion mesh 12.

[0065] Furthermore, the front frame 1122 is lower than the rear frame 1123 to avoid discomfort caused by the front frame 1122 pressing against the user's legs.

[0066] Furthermore, the front frame plate 1122 is inclined upward and connected to the base plate 111, and most of the projection of the front frame plate 1122 on the horizontal plane is located outside the base plate 111, thereby providing better mesh tension for the assembled seat cushion mesh 12 and making it less prone to collapse. In addition, when supporting the user's legs, it can better conform to the human physiological curve and optimize the riding experience.

[0067] Furthermore, the base plate 111 includes a supporting portion 1111 and a curved portion 1112; the curved portion 1112 extends backward and then upward from the rear end of the supporting portion 1111; the cushion bracket 21 connects to the curved portion 1112. In this embodiment, the two extensions of the curved portion 1112 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 1112.

[0068] It should be noted that the rear end of the support part 1111 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.

[0069] Furthermore, such as Figure 13 , 14 As shown, the cross-section along the horizontal plane at the height position of the middle section of the curved surface 1112 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 1112 has a backward-convex smooth arc shape.

[0070] It should be noted that the mid-section height position refers to a small vertical displacement of the curved surface 1112 along its height direction; similarly, the mid-section width position refers to a small horizontal displacement of the curved surface 1112 along its width direction. In this embodiment, Figure 13 This is a cross-sectional view along the horizontal plane at the midpoint of the curved surface in the height direction of 1112. Figure 14 It is a cross-sectional view along the vertical plane at the midpoint of the width direction of the curved surface 1112.

[0071] This can be understood as follows: the arcs on the same horizontal plane of the curved surface 1112 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 1112 extends backward and then upward. The purpose of setting the curved surface 1112 in this shape is to strengthen the structural strength while improving the appearance.

[0072] Furthermore, such as Figure 14 As shown, the smooth arc of the vertical cross-section of the curved surface 1112 includes a first arc and a second arc. The first arc is located on the side closer to the support part 1111, and the second arc is located on the side closer to the backrest part 2. The curvature of the first arc is less than the curvature of the second arc, making the end of the curved surface 1112 closer to the backrest part 2 more curved than the end closer to the seat cushion part 1, thereby further strengthening the structural strength of the product.

[0073] Furthermore, the cantilever frame 112 is at least partially connected to the curved surface 1112. One purpose of this is to increase structural strength and reduce the possibility of fracture or material fatigue at the rear end of the base plate 111 at the cantilever frame 112, especially when the connection between the cantilever frame 112 and the base plate 111 is made using an integral molding process.

[0074] The cantilever frame 112 includes a main frame 1124 and a sub-frame 1125. The main frame 1124 is distributed circumferentially at the edge of the base plate 111. An assembly groove 1126 is provided at the rear end of the main frame 1124. The sub-frame 1125 is connected to the assembly groove 1126 to form a complete cantilever frame 112.

[0075] In this embodiment, the cantilever frame 112, except for a portion of the rear frame plate 1123, comprises a main frame 1124 consisting of the front frame plate 1122, side frame plates 1121, and a portion of the rear frame plate 1123. The main frame 1124 is integrally formed with the base plate 111. The separate sub-frame 1125 is provided for ease of demolding during production. In other embodiments, the cantilever frame 112 may not be divided into a main frame 1124 and a sub-frame 1125; instead, it may be a single, integral unit, fixed to the base plate 111 via bonding, ultrasonic welding, screw connections, or other methods.

[0076] Furthermore, a limiting groove 11261 is provided on the bottom surface of the assembly groove 1126, and a limiting strip 11251 that can be engaged with the limiting groove 11261 is provided at the lower end of the sub-frame portion 1125, which facilitates positioning and installation and reduces the occurrence of sub-frame wobbling. As a simple technical alternative, the positions of the limiting groove 11261 and the limiting block can be interchanged, that is, the limiting strip 11251 is provided at the bottom of the assembly groove 1126, and the limiting groove 11261 is provided at the lower end of the sub-frame portion 1125.

[0077] It also includes a first pressing frame 3; an annular first assembly groove is provided on the outer side wall of the cantilever frame 112, and the seat cushion mesh 12 is fixed to the first assembly groove through the first pressing frame 3, so that the seat cushion mesh 12 is tightly covered with the seat cushion support 11 to form an elastic support surface and improve the comfort of using the seat cushion.

[0078] Furthermore, the seat cushion mesh 12 after tensioning and assembly has a downward-curving slope on the side away from the backrest 2. 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.

[0079] The cushion support 21 includes an assembly frame 210 and a connecting plate 211 connected to one end of the assembly frame 210; the cushion mesh 22 is laid on the assembly frame 210; the connecting plate 211 is rotatably connected to the seat cushion part 1.

[0080] In this embodiment, a hollow 23 is provided in the middle of the assembly frame 210, preferably a complete elliptical or circular hollow 23; the cushion mesh 22 is stretched and laid on the edge of the assembly frame 210.

[0081] Furthermore, such as Figure 7 , 8As shown, the backrest mesh 22, which is tensioned and installed to the assembly frame 210, 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.

[0082] 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 22 in its height direction. Similarly, the mid-width position refers to a small horizontal displacement of the cushion mesh 22 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 direction of the cushion mesh surface 22. Figure 7 This is a cross-sectional view along the vertical plane at the midpoint of the width direction of the cushion mesh 22.

[0083] Furthermore, the assembly frame 210 includes an annular base plate 212, a first reinforcing ring 213, a second reinforcing ring 215, and a clamping plate 216; the first reinforcing ring 213 and the second reinforcing ring 215 are spaced apart on the rear side of the annular base plate 212; the clamping plate 216 is distributed circumferentially along the annular base plate 212, and the padding mesh surface 22 is connected between the clamping plate 216 and the annular base plate 212; one of the purposes is to optimize the structure, so as to ensure the structural strength while taking into account the needs of saving materials and aesthetics.

[0084] Furthermore, an extension plate 214 extends from the lower end of the connecting plate 211; the seat cushion 1 is rotatably connected to the inner side of the connecting plate 211, and the assembled extension plate 214 is located on the outer side of the seat cushion 1. The extension plate 214 increases the contact area between the seat cushion 1 and the backrest 2, shares the pressure at the rotatable connection between the two, and improves the structural strength and service life of the product.

[0085] In this embodiment, the upper end of the rear side of the seat cushion 1 is connected to the lower end of the backrest cushion 2. When in use, the backrest cushion 2 and the seat cushion 1 are set at an angle, and the two form the shape of a chair seat. When in storage, the backrest cushion 2 is close to the seat cushion 1, which reduces the space occupied by this suspended seat cushion, making it easy to carry or store.

[0086] It also includes a second clamping frame; the clamping plates 216 are distributed circumferentially along the annular base plate 212 and form a second assembly groove with an opening facing outward between them. The cushion mesh 22 is fixed to the second assembly groove by the second clamping frame, so that the cushion mesh 22 is tightly covered to the cushion support 21 to form an elastic support surface and improve the comfort of using the sitting cushion.

[0087] Example 2

[0088] As a variation of the above embodiment, the integral molding of the cantilever frame 112 and the base plate 111 is replaced by a separate and fixedly connected arrangement.

[0089] Specifically, the main frame 1124 and the sub-frame 1125 are integrally formed and fixed to the base plate 111 by means of bonding, ultrasonic welding, screw connection and other fixing methods.

[0090] This utility model relates to a suspended seat cushion. By setting a breathable seat cushion mesh and a seat cushion support in the seat cushion part, and setting a lift frame in the seat cushion support, the seat cushion mesh is suspended in the air, which significantly improves the heat dissipation and air circulation of the seat cushion. Furthermore, the user can lean against the backrest of this seat cushion by backing against the backrest part, which can reduce the probability of hunchback, myopia and other diseases caused by the user's forward sitting posture.

[0091] 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.
