By suspending both the seat cushion surface 12 and the backrest back 22, a softer and more comfortable seating experience is provided to the user.

[0053] In the following embodiments, the example is that the seat cushion 11 and the backrest 21 are integrally formed, and the lumbar support 3 is raised and lowered in the vertical direction by rotating the adjustment member 42. Example

[0054] like Figure 1-14 The image shows a preferred embodiment of a suspended sitting cushion.

[0055] The lower end of the backrest 21 is connected to the rear end of the seat cushion 1 and is set at an angle to the seat cushion 1, preferably 90 degrees.

[0056] In this embodiment, preferably, a first skirt 13 is provided on the left and right sides of the seat cushion 11 and on the side away from the backrest 2, for a total of three sides; and a second skirt 23 is provided on the left and right sides of the backrest 21 and on the side away from the seat cushion 11, for a total of three sides.

[0057] Furthermore, the beginning and end ends of the first skirt edge 13 and the beginning and end ends of the second skirt edge 23 are aligned or connected, so that the first skirt edge 13 and the second skirt edge 23 form an integral ring-shaped mounting skirt edge.

[0058] In this embodiment, the first skirt 13 and the second skirt 23 are both continuous, uninterrupted, raised plate-like structures; and the first skirt 13 and the second skirt 23 are connected end to end to form a closed annular plate. In some embodiments, the first skirt 13 and the second skirt 23 may also be formed by multiple spaced-apart plate-like blocks. For example, the first skirt 13 is formed by multiple first skirt segments distributed circumferentially along the outer edge of the seat cushion 11, and the second skirt 23 is formed by multiple second skirt segments distributed circumferentially along the outer edge of the backrest 21; the first skirt segments constituting the starting and ending positions of the first skirt 13 are aligned with the second skirt segments constituting the starting and ending positions of the second skirt 23, thereby forming a spaced-apart but still annular mounting skirt for the first skirt 13 and the second skirt 23.

[0059] The first skirt 13, the second skirt 23, the seat cushion 11, and the backrest 21 together form a concave shell shape. The seat cushion surface 12 is laid on one end of the shell-shaped seat cushion 1, forming a first chamber inside the seat cushion 1. The backrest 22 is laid on one end of the shell-shaped backrest 2, forming a second chamber inside the backrest 2. The first chamber and the second chamber are connected to further optimize heat dissipation. In addition, with the integrated support surface, the force on each position on the support surface can be distributed to the entire mounting skirt, thereby obtaining better support.

[0060] In some less effective embodiments, it is not necessary to provide mounting skirts on all six sides of the seat cushion 11 and the backrest 21. For example, first skirts 13 can be provided only on the left and right sides of the seat cushion 11, and second skirts 23 can be provided on the left and right sides of the backrest 21, for a total of four sides; or, for example, first skirts 13 can be provided only on the side of the seat cushion 11 away from the backrest 2, and second skirts 23 can be provided on the side of the backrest 21 away from the seat cushion 1, for a total of two sides; or, for example, first skirts 13 can be provided on both the left and right sides of the seat cushion 11 and the side away from the backrest 2, and second skirts can be provided on the side of the backrest 21 away from the seat cushion 1. 23. Installation skirts are provided on four sides in total; or for example, a first skirt 13 is provided on the side of the seat cushion 11 away from the backrest 2, and a second skirt 23 is provided on the left and right sides of the backrest 21 and on the side away from the seat cushion 1, for a total of four sides; or for example, a first skirt 13 is provided on the side of the seat cushion 11 away from the left and right sides, and a second skirt 23 is provided on the left and right sides of the backrest 21 and on the side away from the seat cushion 1, for a total of five sides; or for example, a first skirt 13 is provided on the side of the seat cushion 11 away from the left and right sides and away from the backrest 2, and a second skirt 23 is provided on the left and right sides of the backrest 21, for a total of five sides.

[0061] Furthermore, the bottom end of the backrest 22 is connected to the rear end of the seat cushion 12, so that the backrest 22 and the seat cushion 12 form an integral support surface; the support surface is connected to the first skirt 13 and the second skirt 23, so that both the seat cushion 12 and the backrest 22 are suspended.

[0062] Furthermore, both the seat cushion 12 and the backrest 22 are made of flexible and breathable fabric. In this embodiment, preferably, both the seat cushion 12 and the backrest 22 are made of mesh material to avoid the unpleasant user experience caused by stuffiness due to prolonged sitting.

[0063] In this embodiment, the backrest panel 21 and the seat cushion panel 11 are integrally formed to form a cushion-shaped seat. The backrest back panel 22 and the seat cushion surface 12 are also integrally formed, and their edges are fixedly connected to the mounting skirt of the seat. This allows the backrest back panel 22 and the seat cushion surface 12 to be largely separated from the backrest panel 21 and the seat cushion panel 11 and suspended, which can better conform to the physiological curves of the human buttocks and lower back, bringing a softer and more comfortable sitting experience. Furthermore, because the backrest back panel 22 and the seat cushion surface 12 are connected as one piece, the force on any position of the support surface can be distributed into different directional traction forces and dispersed to every position of the entire mounting skirt, thereby giving the support surface stronger and more overall support.

[0064] Furthermore, starting from the seat cushion 1, the second skirt 23 first bends and protrudes towards the seat cushion 1, and then bends away from the seat cushion 1. From the side view, it can be clearly seen that in the vertical direction, the upper half of the second skirt 23 has a bulge towards the seat cushion 1. One of the purposes is to make the backrest 2 provide a better wrapping feeling for the user's lower back, thereby optimizing the support for the lower back.

[0065] Furthermore, a first protruding edge 14 is provided on the outer side of the first skirt edge 13, and a second protruding edge 24 is provided on the outer side of the second skirt edge 23; a third protruding edge 15 is provided behind the first protruding edge 14, and a fourth protruding edge 25 is provided behind the second protruding edge 24; the first protruding edge 14 and the third protruding edge 15 are spaced apart, and a first mounting groove 16 is formed between them; the second protruding edge 24 and the fourth protruding edge 25 are spaced apart, and a second mounting groove 26 is formed between them; the seat cushion surface 12 is connected to the first mounting groove 16; the backrest 22 is connected to the second mounting groove 26.

[0066] Preferably, in this embodiment, the first protruding edge 14 and the second protruding edge 24 are connected to form an annular protrusion, and the third protruding edge 15 and the fourth protruding edge 25 are also connected to form an annular protrusion. Therefore, the first assembly groove 16 and the second assembly groove 26 are connected to form an assembly groove along the seated pad surface and the outer periphery of the pad surface.

[0067] In this embodiment, after the mesh fabric forming the support surface is sewn with adhesive strips, the mesh fabric is installed and fixed along the mounting groove on the outer periphery of the housing, which can protect the edge of the support surface from being bumped and damaged, and can also improve the product's aesthetics.

[0068] To further improve the breathability and heat dissipation of the seat cushion, at least one first through hole 17 is provided on the seat cushion plate 11; and / or at least one second through hole 27 is provided on the backrest plate 21.

[0069] Furthermore, a first reinforcing edge 171 extends circumferentially from the first through hole 17, which is suitable for strengthening the structural strength around the first through hole 17; a second reinforcing edge 271 extends circumferentially from the second through hole 27, which is suitable for strengthening the structural strength around the second through hole 27.

[0070] In this embodiment, two first through holes 17 are respectively provided on both sides of the bottom of the seat cushion 11, and the two sets of four first through holes 17 are symmetrically distributed. The first reinforcing edge 171 extends from the edge of the first through hole 17 toward the seat cushion surface 12 at a certain height. A second through hole 27 is respectively provided on the left and right sides of the upper half of the backrest 21, and the two sets of two second through holes 27 are symmetrically distributed. The second reinforcing edge 271 extends from the edge of the second through hole 27 toward the seat cushion surface 12 at a certain height. By providing the first reinforcing edge 171 and the second reinforcing edge 271, the structural strength of the seat cushion 11 and the backrest 21 is increased, thereby improving the functional stability and service life of the product.

[0074] In this embodiment, several second mounting plates 19 are provided, and the array of second mounting plates 19 is distributed in the third mounting groove. The two ends of the second mounting plates 19 are respectively connected to the first mounting plate 18 and the seat cushion plate 11. Through the cross arrangement of the first mounting plate 18 and several second mounting plates 19, and supplemented by the first mounting groove 51 and several second mounting grooves 52, the leg cushion block 5 is better fixed to the front end of the seat cushion 1, that is, the end away from the backrest 2, so that it can always provide good cushioning and support for the lower side of the user's legs and optimize the user experience.

[0075] Furthermore, the side of the seat cushion 12 away from the backrest 21 has a downwardly curved slope, preferably a curved surface with an arc.

[0076] The leg cushioning block 5 is preferably located below the slope and is made of a soft material; one of its purposes is to form a soft cushioning area under the user's legs to reduce the discomfort caused by compression of the thighs.

[0077] Furthermore, it also includes a lumbar support 3 and an adjustment mechanism 4; the lumbar support 3 is connected to the backrest 2 and is located behind the backrest 22, that is, between the backrest 22 and the backrest panel 21; the adjustment mechanism 4 connects the backrest panel 21 and the lumbar support 3, and includes an adjustment member 42 and a stop member 41; the adjustment member 42 has a plurality of adjustment teeth 421; a plurality of stop grooves 411 are distributed along a predetermined direction on the stop member 41; by rotating the adjustment member 42, the plurality of adjustment teeth 421 can be sequentially engaged with different stop grooves 411, thereby driving the lumbar support 3 to move in the predetermined direction. For example, if the stop grooves 411 are distributed along the vertical direction, that is, the height direction, it adjusts the vertical rise and fall of the lumbar support 3; or, for example, if the stop grooves 411 are distributed along the horizontal direction, it adjusts the horizontal translation of the lumbar support 3.

[0078] In this embodiment, the stop grooves 411 on the stop member 41 are arranged and distributed along the height direction.

[0079] The stop member 41 is fixedly connected to the lumbar support part 3 and slidably connected to the backrest plate 21; the adjusting member 42 is rotatably connected to the backrest plate 21 and connected to the stop member 41, so that the adjusting teeth 421 are movably set in the stop groove 411; when it is necessary to adjust the height of the lumbar support part 3, rotating the adjusting member 42 will cause different adjusting teeth 421 to be engaged in the next stop groove 411 in sequence, thereby driving the stop member 41 to slide upward or downward, thereby achieving the purpose of adjusting the height of the lumbar support part 3.

[0080] Furthermore, a pair of guide rails 28 are provided in the middle of the backrest panel 21; the guide rail 28 includes a vertical plate and a horizontal plate, with the two ends of the vertical plate connected to the backrest panel 21 and the horizontal plate respectively, so that the cross section of the guide rail 28 presents an L-shape, and a groove 29 is formed between the horizontal plate and the backrest panel 21; the stop member 41 is slidably connected to the two grooves 29 formed by the two horizontal plates and the backrest panel 21 respectively, and is limited by the two grooves 29.

[0081] In this embodiment, the two sides of the stop member 41 are respectively slidably connected to a slide groove 29 and respectively limited by a horizontal plate, so that the stop member 41 will not move away from the backrest 21 during the sliding process, thus ensuring the functional stability of the product.

[0089] As a variation of the above embodiment, the stop member 41 is replaced by a fixed setting instead of a sliding setting, and the adjustment member 42 is replaced by a sliding and rotatable setting instead of a rotatable setting.

[0090] Specifically, a sliding groove is provided on the backrest panel 21; a stop member 41 is fixedly connected to the backrest panel 21, the stop groove 411 is located at the edge of the sliding groove, and each stop groove 411 is connected to the sliding groove; the adjustment member 42 is rotatably connected to the lumbar support 3, and the adjustment member 42 can slide in the sliding groove.

[0091] The adjusting member 42 is fixedly connected to the waist support part 3 via the mounting shaft, and the adjusting member 42 can rotate around the mounting shaft.

[0092] In this embodiment, preferably, the adjusting member 42 can rotate in the sliding groove. When the adjusting member 42 is rotated, the adjusting tooth 421 disengages and engages with another stop groove 411, while the adjusting member 42 slides in the sliding groove, thereby driving the lumbar support 3 to adjust its height position up and down. In other embodiments, a guide slider is also included, which can slide in the sliding groove, and the adjusting member 42 is rotatably mounted on the guide slider.

[0093] This utility model discloses a suspended posture cushion, particularly a breathable mesh lumbar support posture cushion. By incorporating a raised first skirt on the seat cushion panel, with the seat surface connected to the upper part of the first skirt, and a raised second skirt on the backrest panel, with the backrest connected to the upper part of the second skirt, both the seat surface and backrest are suspended, providing a softer and more comfortable sitting experience. Furthermore, by resting their back against the backrest of this posture cushion, users can reduce the probability of developing hunchback and nearsightedness caused by forward-leaning posture.

[0094] 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.
