Although such seat cushions can provide basic cushioning, they are prone to plastic deformation after long-term pressure use, which reduces the support stability. Moreover, different users have different body curves, and existing seat cushions are difficult to conform to individual differences in body shape, which is not conducive to improving the user experience. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a multi-zone seat cushion that can adapt to individual user differences, improve support, and enhance the user experience.

[0004] A multi-zone seat cushion according to a first aspect of the present invention includes a base plate, multiple airbags, and multiple one-way valves. The multiple airbags are spaced apart on the base plate. Each airbag includes an elastic layer and two sealing layers. The elastic layer is disposed between the two sealing layers, and the edge of each sealing layer is sealed to the base plate. The base plate and the inner sealing layer form a cavity. A one-way valve passes through each airbag, and each one-way valve corresponds to one airbag. A plug is detachably connected to the air inlet of each one-way valve, and the air outlet of each one-way valve communicates with the cavity. The elastic layer drives the sealing layers to expand away from the base plate, allowing airflow to pass through the one-way valve and enter the cavity.

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0021] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0022] Understandably, referring to Figures 1 to 4The multi-zone seat cushion of this utility model includes a base plate 100, multiple airbags 200, and multiple one-way valves 300. The multiple airbags 200 are arranged at intervals on the base plate 100. Each airbag 200 includes an elastic layer 210 and two sealing layers 220. The elastic layer 210 is arranged between the two sealing layers 220. The edge of the sealing layer 220 is sealed to the base plate 100. The base plate 100 and the inner sealing layer 220 form a cavity 240. The one-way valves 300 are inserted into the airbags 200. The one-way valves 300 correspond one-to-one with the airbags 200. The air inlet end of the one-way valve 300 is detachably connected to a plug 310. The air outlet end of the one-way valve 300 is connected to the cavity 240. The elastic layer 210 is used to drive the sealing layer 220 to expand away from the base plate 100 so that the airflow can pass through the one-way valve 300 and enter the cavity 240.

[0023] Multiple airbags 200 are spaced apart on the base plate 100. Each airbag 200 is equipped with a one-way valve 300. The airbag 200 includes an elastic layer 210 and two sealing layers 220. The elastic layer 210 is arranged between the two sealing layers 220, and the edge of the sealing layer 220 is sealed to the base plate 100, so that the base plate 100 and the inner sealing layer 220 form a cavity 240. By removing the plug 310 from the one-way valve 300, the elastic layer 210 can drive the sealing layer 220 to expand away from the base plate 100, so that the airflow passes through the one-way valve 300 and enters the cavity 240, thereby realizing the automatic inflation of the airbag 200 without the need for inflation adjustment by an air pump, improving the adjustment convenience of the airbag 200. By setting multiple airbags 200 on the base plate 100, the inflation volume of each airbag 200 can be adjusted, thereby allowing the seat cushion to adapt to individual differences of users, so as to conform to the user's body curves, improve support, and enhance the user experience.

[0024] It should be noted that the airbag 200 is initially in a compressed state, making the internal air pressure of the airbag 200 lower than the external air pressure. When the plug 310 is removed from the one-way valve 300, the elastic layer 210 can reset and drive the sealing layer 220 to expand away from the base plate 100, thereby allowing airflow to pass through the one-way valve 300 and enter the cavity 240, so that the airbag 200 can be automatically inflated without the need for an additional air pump, improving the convenience of adjustment.

[0025] In addition, multiple airbags 200 are spaced apart on the base plate 100, and the inflation volume of each airbag 200 can be adjusted to facilitate the adjustment of the support strength and position of the airbags 200. This allows each airbag 200 to conform to the user's body curve, improve the support effect of the seat cushion, and enhance the user experience.

[0026] Specifically, the elastic layer 210 can be made of sponge, memory foam or other elastic materials, so that the elastic layer 210 has a stable shape in its natural state, so that the elastic layer 210 can pull the sealing layer 220 to expand and deform. This not only achieves the automatic inflation effect, but also makes the seat cushion have an elastic cushioning effect, improving the user experience of the seat cushion.

[0027] In addition, the sealing layer 220 can be a non-breathable material such as rubber or leather, so that the amount of air in the cavity 240 can remain stable.

[0028] Understandably, referring to Figure 2 and Figure 3 An adhesive layer 230 is provided between the elastic layer 210 and the sealing layer 220, which is used to fix the elastic layer 210 and the sealing layer 220 together. The adhesive layer 230 stably bonds the elastic layer 210 and the sealing layer 220 together, so that the elastic layer 210 and the sealing layer 220 can be stably connected during the inflation of the airbag 200, preventing the elastic layer 210 from separating from the sealing layer 220. This not only makes the airbag 200 inflate smoothly, but also avoids the formation of voids between the elastic layer 210 and the sealing layer 220, so that the inner sealing layer 220 can more effectively transmit the elasticity of the elastic layer 210 and improve the support effect of the seat cushion.

[0029] It should be noted that the adhesive layer 230 can be glue, so that the elastic layer 210 and the sealing layer 220 can be stably connected together.

[0030] Understandably, referring to Figure 2 and Figure 4The one-way valve 300 includes a connecting seat 320 and a valve plate 330. The connecting seat 320 is inserted into the airbag 200 and has a through hole 321. One end of the through hole 321 is connected to a plug 310, and the other end of the through hole 321 is provided with a buckle 322. The valve plate 330 is connected to the buckle 322 so that the valve plate 330 can open or close the through hole 321. The connecting seat 320 is inserted into the airbag 200 and has a through hole 321. One end of the through hole 321 is connected to the plug 310, and the other end is provided with a buckle 322 to connect the valve plate 330. When inflation is needed, the plug 310 is pulled out of the through hole 321. Under the action of the elastic layer 210 driving the sealing layer 220 to expand and generate negative pressure, the external airflow can push open the valve plate 330, allowing the airflow to enter the cavity 240 through the through hole 321, thus achieving automatic inflation. When inflation is complete, the plug 310 is pushed back into the through hole 321, so that the valve plate 330 tightly fits the end face of the through hole 321 under the action of air pressure, thereby closing the through hole 321 and effectively preventing gas leakage from the airbag 200. This ensures the stability of the inflation volume in the airbag 200, allowing the seat cushion to continuously provide stable support for the user, improving the performance and reliability of the seat cushion, and further enhancing the user experience.

[0031] It should be noted that the edge of the valve plate 330 is engaged with the buckle 322 so that the valve plate 330 can be bent and deformed around the buckle 322 to open or close the through hole 321.

[0032] Specifically, refer to Figure 2 and Figure 4 The valve plate 330 is provided with a connecting post 331, which passes through the through hole 321. The connecting post 331 is connected to the valve plate 330. By setting the connecting post 331 to pass through the through hole 321, the deformation of the valve plate 330 is limited, so that the valve plate 330 can smoothly open or close the through hole 321, preventing the valve plate 330 from falling out of the latch 322 and improving the reliability of the one-way valve 300.

[0033] It should be noted that when the airbag 200 is inflated, the airflow can push open the valve plate 330 and cause the connecting post 331 to abut against the inner wall of the through hole 321, thereby limiting the deformation of the valve plate 330 and preventing the valve plate 330 from coming off the buckle 322; when the airbag 200 is deflated, the user can press the connecting post 331 to make the connecting post 331 drive the valve plate 330 to separate from the connecting seat 320, thereby expelling the air in the cavity 240 by pressing the airbag 200, improving the user's convenience.

[0034] Specifically, refer to Figure 2 and Figure 4The inner wall of the through hole 321 is surrounded by a groove 323, and the outer wall of the plug 310 is provided with a connecting part 311 protruding outwards. The connecting part 311 can be engaged in the groove 323. The groove 323 is arranged around the inner wall of the through hole 321, and the outer wall of the plug 310 is provided with a connecting part 311 protruding outwards. By engaging the connecting part 311 in the groove 323, the connection between the plug 310 and the through hole 321 is more stable and reliable, which can reduce the possibility of the plug 310 falling out of the through hole 321, improve the reliability of the one-way valve 300, and avoid gas leakage affecting the inflation and gas retention effect of the airbag 200.

[0035] Specifically, refer to Figure 2 and Figure 4 Along the axial section of the through hole 321, the connecting part 311 is shaped as a semi-circle, and the groove 323 matches the connecting part 311. By setting the shape of the connecting part 311 as a semi-circle, the resistance encountered by the connecting part 311 during the process of inserting and removing the groove 323 can be reduced, making the installation and removal of the plug 310 more convenient and improving the ease of operation for users.

[0036] In addition, the groove 323 matches the shape of the connecting part 311, thereby increasing the contact area between the plug 310 and the connecting seat 320, so that the plug 310 and the connecting seat 320 can be tightly connected, improving the sealing effect of the one-way valve 300 and enhancing the reliability and durability of the seat cushion.

[0037] Understandably, referring to Figure 5 and Figure 6 The base plate 100 is connected to an air pump 110. The output end of the air pump 110 is connected to multiple air supply pipes 120. Each air supply pipe 120 corresponds one-to-one with an airbag 200 and is connected to the airbag 200. The air pump 110 is used to supply air to the air supply pipes 120. The output end of the air pump 110 is connected to multiple air supply pipes 120, and each air supply pipe 120 is connected to an airbag 200, so that the air pump 110 can supply air to the airbag 200 through the air supply pipes 120, thereby improving the inflation efficiency of the airbag 200, increasing the inflation pressure of the airbag 200, and improving the usability of the seat cushion.

[0038] It should be noted that the air pump 110 can fill the airbag 200, and then the user can release the air in the airbag 200 through the one-way valve 300 until the air pressure in the airbag 200 meets the user's needs, thus improving the efficiency of adjustment.

[0039] Understandably, referring to Figure 1The number of airbags 200 is set to 4, and the 4 airbags 200 are evenly distributed around the circumference of the base plate 100. The even distribution of the 4 airbags 200 around the circumference of the base plate 100 allows the seat cushion to better conform to the user's body curves and effectively distribute body pressure, avoiding poor blood circulation and fatigue caused by excessive local pressure.

[0040] In addition, the evenly spaced airbags 200 make the support of the seat cushion more balanced in all directions, so that users can get a stable and comfortable support experience no matter what sitting posture they use, which improves the comfort and practicality of the seat cushion and meets the diverse usage needs of different users.

[0041] Understandably, referring to Figure 3 The elastic layer 210 is made of polyurethane foam. By making the elastic layer 210 of polyurethane foam, the cushion can deform when the user sits down to conform to the body curve, providing even support, effectively distributing body pressure, reducing local pressure, and thus improving the comfort of the cushion.

[0042] In addition, by setting the elastic layer 210 to be a polyurethane foam component, the elastic recovery force of the elastic layer 210 can be enhanced, so that the elastic layer 210 can smoothly push the sealing layer 220 to expand, thereby improving the automatic inflation stability of the airbag 200.

[0043] Specifically, refer to Figure 3 The sealing layer 220 is made of thermoplastic polyurethane or polyvinyl chloride. By making the sealing layer 220 a thermoplastic polyurethane or polyvinyl chloride component, the wear resistance and sealing performance of the sealing layer 220 can be improved, reducing the possibility of air leakage caused by wear and cracking, which helps to extend the service life of the cushion. At the same time, the sealing layer 220 has good flexibility, so as to facilitate the tight fit between the sealing layer 220 and the base plate 100, enhance the sealing effect, and improve the reliability of the cushion.

[0044] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
