[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0029] Example 1

[0030] This embodiment discloses a novel inflatable water seat, the overall structure of which is as follows: Figure 1 and Figure 2 As shown, it includes an inflatable seat body. For the water inflatable seat disclosed in this embodiment, the inflatable seat body mainly refers to the horizontally distributed inflatable seat cushion 1 and the vertically distributed inflatable backrest 2.

[0031] The inflatable seat cushion 1 primarily contacts the buttocks area, such as... Figure 4 As shown, the inflatable seat cushion 1 is designed with two independent air chambers: an inner air chamber 1b and an outer air chamber 1a surrounding the inner air chamber 1b. The inner air chamber 1b is equipped with an independent inner air chamber inflation / deflation valve 101, which is located on the upper surface of the inflatable seat cushion 1 and is used for inflating and deflating the inner air chamber 1b. Similarly, the outer air chamber 1a is equipped with an independent outer air chamber inflation / deflation valve 102, which is located on one side surface of the inflatable seat cushion 1 and is used for inflating and deflating the outer air chamber 1a.

[0032] Because the inner air chamber 1b and the outer air chamber 1a are distributed in an inner and outer ring, and each has an independent air chamber and inflation / deflation valve, the safety of the inflatable seat 1 is improved. In the event of a leak in one air chamber, the other air chamber can still maintain the normal use of the inflatable seat 1 as much as possible. On the other hand, it can support different inflation pressures between the inner and outer air chambers. During inflation, the outer air chamber 1a can be fully inflated, while the inner air chamber 1b is inflated with relatively less air than the outer air chamber 1a. As a result, the inflatable seat 1 where the inner air chamber 1b is located is softer than the inflatable seat 1 where the outer air chamber 1a is located. Based on this, the area of ​​the seat that contacts the buttocks (i.e., the inflatable seat 1 where the inner air chamber 1b is located) has a concave design feature, which better conforms to the curve of the human buttocks, so as to distribute the pressure on the buttocks and improve the comfort of the inflatable seat.

[0033] Furthermore, regarding the inner ring chamber 1b and the outer ring chamber 1a, as follows: Figure 4 As shown, the inflatable seat cushion 1 is divided into inner and outer rings by a PVC partition 106. The top of the PVC partition 106 is fixedly bonded to the top layer of the inflatable seat cushion 1, and the bottom of the PVC partition 106 is fixedly bonded to the bottom layer of the inflatable seat cushion 1.

[0034] For the inflatable seat cushion 1, PVC brushed air cushion fabric is used. PVC brushed air cushion fabric is known to have advantages such as high strength, high elasticity, and good flexibility, providing a comfortable feel and good elastic recovery while ensuring the structural strength of the seat. Furthermore, the material's density is less than that of water, giving it buoyancy and making it suitable for water-based recreational activities.

[0035] Typically, brushed air cushion fabric uses three-dimensional weaving technology, which involves first weaving two layers of mesh fabric with polyester yarn, then connecting the vertices of the mesh to form X-shaped brushing units, and finally coating the surface of the mesh fabric with PVC coating, thus forming brushed fabric.

[0036] For ease of description, such as Figure 3 As shown, the inflatable seat cushion 1 is divided into a bottom PVC mesh fabric 103 and a top PVC mesh fabric 104. During the filament weaving process between the bottom PVC mesh fabric 103 and the top PVC mesh fabric 104, PVC spacer fabric 106 is fixedly bonded to the bottom PVC mesh fabric 103 and the top PVC mesh fabric 104 respectively, thereby pre-integrating the PVC spacer fabric 106 into the filament air cushion fabric of the inflatable seat cushion 1. After the edges are finished, the connecting gaps at the edges of the bottom PVC mesh fabric 103 and the top PVC mesh fabric 104 are sealed using the side sealing fabric 105. Then, PVC cosmetic strips are used for conventional finishing treatment, thus obtaining the main body of the inflatable seat cushion 1.

[0037] Preferably, an EVA cushioning cushion 4 is further bonded and fixed to the upper surface of the inflatable cushion part 1 to provide protection and increase comfort.

[0038] The inflatable backrest 2 is located above the rear end of the inflatable seat cushion 1, primarily contacting the back area. The inflatable backrest 2 has a separate air chamber independent of the inflatable seat cushion 1, and is equipped with a backrest inflation / deflation valve 201. Figure 2 As shown, the backrest inflation / deflation valve 201 is located on the rear side of the inflation backrest 2 and is used for inflation and deflation of the internal air chamber of the inflation backrest 2.

[0039] For example Figure 1 and Figure 2 As shown, the inflatable backrest 2 has a forward-facing support protrusion 2a at the middle position. The support protrusion 2a is arc-shaped and can provide strong support for the waist, maintaining the natural physiological curvature of the waist. Furthermore, through the connection of the support protrusion 2a, the upper part of the inflatable backrest 2 tilts backward and the lower part protrudes slightly forward, making the entire inflatable backrest more conform to the curve of the human back, effectively relieving back muscle pressure, and further improving the comfort of this inflatable seat.

[0040] Similar to the inflatable seat cushion 1, the inflatable backrest 2 also uses PVC brushed air cushion fabric. For ease of description, as shown below... Figure 5 As shown, the inflatable backrest 2 is divided into a front PVC mesh fabric 202 and a rear PVC mesh fabric 203. The front and rear PVC mesh fabrics 202 and 203 are woven together and then bent and fixed along the mold shape using a high-frequency heat-sealing machine under heat and pressure. After cooling, the PVC coating maintains the bending angle due to the heat-setting effect, and even when subjected to internal air pressure after inflation, it can still maintain the preset bending shape. Furthermore, the seams connecting the front and rear PVC mesh fabrics 202 and 203 are sealed around their edges using a backrest side sealing fabric 204. Finally, PVC cosmetic strips are used for conventional finishing treatment, resulting in the main body of the inflatable backrest 2.

[0041] Preferably, an EVA cushioning pad 5 adapted to the shape of the front surface of the inflatable backrest 2 is fixedly laid on the front surface of the inflatable backrest 2 to provide protection and increase comfort.

[0042] In addition, preferably, a lifting handle 6 is provided on the top of the inflatable backrest 2 for easy lifting and use.

[0043] D-rings 8 are symmetrically arranged on both sides of the inflatable backrest 2 via D-ring PVC cloth 7 to facilitate the fixing and use of the seat.

[0044] A mesh pocket 9 is provided on the back of the inflatable backrest 2, which can be used to hold items.

[0045] In summary, the novel inflatable water seat disclosed in this embodiment features an inner and outer ring design for the air chambers of the inflatable seat cushion 1. Without affecting the floating function of the inflatable seat cushion, the inner ring air chamber makes the inflatable seat cushion softer than the outer ring air chamber. This results in a concave design in the seat area that contacts the buttocks, better conforming to the curve of the human buttocks to distribute pressure and improve the comfort of the inflatable seat. The inflatable backrest has a supportive protrusion structure that provides strong support for the lower back, maintaining the natural physiological curvature of the lower back, further enhancing the comfort of the inflatable seat.

[0046] Example 2

[0047] This embodiment discloses a novel inflatable water seat. Based on the structure disclosed in Embodiment 1, the inflatable seat cushion 1 and the inflatable backrest 2 included in the main body of the inflatable seat are connected by a PVC connecting hinge cloth 3.

[0048] The PVC connecting hinge cloth 3 is divided into an inner connecting hinge cloth 31 and an outer connecting hinge cloth 32; wherein, the inner connecting hinge cloth 31 is connected on the inside of the corner where the inflatable seat cushion 1 and the inflatable backrest 2 are connected, and the outer connecting hinge cloth 32 is connected on the outside of the corner where the inflatable seat cushion 1 and the inflatable backrest 2 are connected.

[0049] The length of the outer connecting hinge cloth 32 should be greater than the length of the inner connecting hinge cloth 31. When the inflatable seat cushion 1 and the inflatable backrest 2 are inflated respectively, the inner connecting hinge cloth 31 and the outer connecting hinge cloth 32 are in a taut state, so that the inflatable seat cushion 1 and the inflatable backrest 2 are stably in the seat use state.

[0050] Therefore, for the novel inflatable water seat disclosed in this embodiment, the inflatable seat cushion 1 and the inflatable backrest 2 are assembled and connected as one unit using PVC connecting hinge cloth 3 made of PVC material. While not affecting the folding and storage of the inflatable seat after deflation, it can also be tightened and limited in the front and back when inflated, so that the inflatable seat cushion 1 and the inflatable backrest 2 are stably in the seat use state.

[0051] Example 3

[0052] This embodiment discloses a novel inflatable water seat. Based on the structure disclosed in Embodiment 2, and considering the problem that existing inflatable seats cannot be folded and stored in an orderly manner, the inflatable seat disclosed in this embodiment further provides a reinforcing layer on the air cushion 1 and the inflatable backrest 2. The reinforcing layer is a PVC cloth layer, which serves to thicken and protect the seat.

[0053] As shown in Figure 2, the specific details are as follows: Figure 2As shown, a seat cushion reinforcement layer 12 is fixedly laid on the lower surface of the inflatable seat cushion part 1. The seat cushion reinforcement layer 12 is divided into two sections, which are separated by a gap 13. An upper reinforcement layer 10 is fixedly laid on the upper half of the back side surface of the inflatable backrest 2, and a lower reinforcement layer 11 is fixedly laid on the lower half of the back side surface of the inflatable backrest 2. The upper reinforcement layer 10 and the lower reinforcement layer 11 are separated by a support protrusion 2a.

[0054] Therefore, when this new type of inflatable water seat is deflated and folded for storage, such as Figure 6 As shown, the upper half of the inflatable backrest 2 is folded downwards along the support protrusion 2a toward the back side, and then the lower half of the inflatable backrest 2 is folded toward the upper position of the inflatable seat cushion 1. Finally, the inflatable seat cushion is folded and stored along the gap 13. Thus, the inflatable seat can be quickly and conveniently folded and stored in sequence through three steps, thereby improving the ease of use of this inflatable seat.

[0055] The above embodiments are not intended to limit the present invention, nor is the present invention limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present invention are also within the protection scope of the present invention.
