One-way air inlet component and airbag cushion with one-way air inlet component

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese utility model patent application with application number 202323456912.3, filed with the China Patent Office on December 16, 2023, and entitled “One-way air intake component and a cushioning airbag cushion having a one-way air intake component”, and the Chinese invention patent application with application number 202311745936.2, filed on the same day, and entitled “One-way air intake component and a cushioning airbag cushion having a one-way air intake component”, all contents of which are incorporated by reference into this application. Technical Field

[0003] The invention belongs to the field of daily necessities, and in particular relates to a one-way air inlet component and a buffer airbag cushion. Background Art

[0004] Airbag cushions, as products that provide buffering pressure, are widely used in various products, such as bag shoulder straps, seat cushions, back cushions, mattresses, shoe insoles and other cushioning pads, which can buffer the pressure of the user's contact parts.

[0005] However, the existing airbag cushion has a problem that after the gas enters the airbag of the airbag cushion, part of the gas will slowly leak out through the air inlet. Therefore, the entire airbag cushion has a slow air leakage phenomenon, which causes the user to have insufficient gas in the airbag after using the cushion for a period of time and need to inflate it again, which makes it inconvenient to use.

[0006] Existing one-way air inlet components include an air inlet portion and an air outlet portion. The air inlet portion receives gas from the ventilation duct of the first airbag, while the air outlet portion communicates with the air inlet portion and the interior of the second airbag. The air outlet portion is suspended within the second airbag and remains closed when not emitting gas, preventing gas from the second airbag from flowing back into the first airbag. However, the inventors have discovered that during the process of attaching the one-way air inlet component to the upper and lower cushion bodies, the air outlet portion of the one-way air inlet component can easily deform and bend, resulting in the air outlet portion drooping and bending relative to the air inlet portion. Consequently, when inflating the airbag cushion, gas cannot smoothly enter the bent air outlet portion after entering the air inlet portion, resulting in inflation failure and inconvenient use.

[0007] Summary of the Invention

[0008] The present invention provides a one-way air inlet component that is smoothly inflated and easy to use, and a buffer airbag cushion having the one-way air inlet component.

[0009] A technical solution of the present invention is a one-way air intake component, which is used for one-way air intake of a buffer airbag cushion. The buffer airbag cushion includes a first airbag and a second airbag that are interconnected. The first airbag is connected to the air inlet of the buffer airbag cushion, and the air inlet is connected to the outside. A one-way air intake channel is provided inside the one-way air intake component. The one-way air intake channel is a structure with an opening connected to the air inlet on one side and is closed on the other sides. The one-way air intake component is installed on the first airbag, or the second airbag, or between the first airbag and the second airbag, so that the one-way air intake component is in a non-bent state when the buffer airbag cushion is in a non-bent state. An air outlet is provided on the one-way air intake channel at a position away from the opening, and the air outlet supplies air to the second airbag in a one-way manner.

[0010] Furthermore, the one-way air inlet member includes: an air inlet portion, which is arranged at one end of the opening side of the one-way air inlet channel and is fixed at least at the connection between the first airbag and the second airbag, and includes the opening, and the air inlet portion is fixed to the buffer airbag cushion; a fixing portion, which is arranged at the other end of the one-way air inlet member away from the air inlet portion and is installed on the periphery of the second airbag opposite to the first airbag; and an air outlet portion, which is arranged on a side of the one-way air inlet channel away from the air inlet portion and includes the air outlet, and the air outlet is arranged in the second airbag and is located between the air inlet portion and the fixing portion. The one-way air inlet channel is opened and closed under air pressure difference. When the one-way air inlet channel is open, the air inlet portion is connected to the air outlet portion. When the one-way air inlet channel is closed, the air inlet portion is not connected to the air outlet portion.

[0011] Furthermore, in the one-way air inlet member, the air inlet portion of the one-way air inlet member is provided at an air inlet passage connecting the first airbag and the second airbag and the first airbag.

[0012] Furthermore, the one-way air inlet component includes: an air inlet portion, which is arranged at one end of the opening side of the one-way air inlet channel and includes the opening, and the air inlet portion is fixed to the buffer airbag cushion in a manner of being connected to the air inlet port; a fixing portion, which is arranged at the other end of the one-way air inlet component away from the air inlet portion and fixed to the connection between the first airbag and the second airbag; and an air outlet portion, which is arranged on a side of the one-way air inlet channel away from the air inlet portion and includes the air outlet, and the air outlet is arranged in the second airbag and located between the air inlet portion and the fixing portion. The one-way air inlet channel is opened and closed under air pressure difference. When the one-way air inlet channel is open, the air inlet portion is connected to the air outlet portion, and when the one-way air inlet channel is closed, the air inlet portion is not connected to the air outlet portion.

[0013] Furthermore, the one-way air inlet component includes a closing portion, and the closing portion overlaps with the air outlet at least in part, or the closing portion does not overlap with the air outlet and is arranged around the air outlet.

[0014] Furthermore, in the one-way air inlet component, the air outlet has multiple outlets, including a first air outlet and a second air outlet.

[0015] The closing portion overlaps at least partially with one or both of the first and second air outlets, or the closing portion does not overlap with either of the first and second air outlets and is provided around either of the first and second air outlets.

[0016] Furthermore, in the one-way air inlet member, the one-way air inlet member is formed by combining a thin film upper piece and a thin film lower piece.

[0017] The upper piece and the lower piece at the folded portion are combined together,

[0018] The upper piece and the lower piece at the air outlet are separated when the one-way air inlet member performs one-way air intake.

[0019] Furthermore, in the one-way air inlet member, the one-way air inlet member is formed by combining a thin film upper piece and a thin film lower piece.

[0020] The inner walls of the upper piece and the lower piece that contact each other are smooth.

[0021] Furthermore, in the one-way air intake member, the side edges on one side or both sides of the one-way air intake member extend beyond the bulging area of ​​the second airbag and are fixed to the periphery of the second airbag, or the side edges on one side or both sides of the one-way air intake member extend beyond the bulging area of ​​the first airbag and are fixed to the periphery of the first airbag.

[0022] Another technical solution of the present invention is a buffer airbag cushion, which includes: multiple airbags, including a first airbag, which has an air inlet connected to the outside; and a second airbag, which is connected to the first airbag; multiple air ducts, which connect and communicate with the multiple airbags, and have air inlet ducts connecting and communicating with the first airbag and the second airbag; and a one-way air inlet member, which is used to provide one-way air intake to the buffer airbag cushion, the first airbag is connected to the air inlet of the buffer airbag cushion, and the air inlet is connected to the outside, a one-way air inlet channel is provided inside the one-way air inlet member, the one-way air inlet channel is a structure with an opening connected to the air inlet on one side and closed on the other sides, the one-way air inlet member is installed in the first airbag, or the second airbag, or between the first airbag and the second airbag, so that the one-way air inlet member is in a non-bent state when the buffer airbag cushion is in a non-bent state, and an air outlet is provided at a position away from the opening of the one-way air inlet channel, and the air outlet supplies air to the second airbag in a one-way manner.

[0023] The present application can prevent slow gas leakage through such a one-way air inlet component and a buffer airbag cushion, thereby effectively preventing air leakage of the buffer airbag cushion. There is no need to inflate it frequently, which is easy to use. It can also prevent the one-way air inlet component from curling up and failing to achieve good gas circulation, thereby increasing its service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0044] 1 and 2 show a buffer airbag cushion 200 according to the present invention, which includes a main body 201 and an airbag auxiliary component 100 disposed on the main body 201 .

[0045] The body 201 includes a plurality of air passages 203 and a plurality of airbags 205 connected through the plurality of air passages 203. The airbag auxiliary component 100 is connected to the plurality of airbags 205 to control the air inlet and outlet of the plurality of airbags 205. The plurality of air passages 203 and the plurality of airbags 205 are convex.

[0046] In this embodiment, the main body 201 also includes an upper cushion body 207 and a lower cushion body 209. The upper cushion body 207 is formed with multiple air channels 203 and multiple air bags 205 arranged in a prescribed shape. The lower cushion body 209 is bonded to the portion of the upper cushion body 207 where the multiple air channels 203 and the multiple air bags 205 are not formed, so that the multiple air channels 203 and the multiple air bags 205 are formed by the upper cushion body 207 and the lower cushion body 209 fitting and sealing.

[0047] The airbag auxiliary component 100 includes an air inlet assembly 10 and an air outlet assembly 80. The air inlet assembly 10 is used to allow external air to unidirectionally inflate the plurality of airbags 205, and the air outlet assembly 80 is used to discharge the air in the plurality of airbags 205 to the outside.

[0048] The air inlet assembly 10 is connected to adjacent airbags 205 in the plurality of airbags 205 via at least one air channel 203, and functions to pressurize gas from the outside into the plurality of airbags 205 in the body 201. The air outlet assembly 80 is connected to adjacent airbags 205 via at least one air channel 203, and functions to release gas from the plurality of airbags 205 in the body 201. The air inlet assembly 10 and the air outlet assembly 80 are not directly connected, but are connected and communicated via the plurality of airbags 205 and the plurality of air channels 203 connected in series.

[0049] 1 and 2 , the specific structure of the airbag auxiliary component 100 will be described in detail.

[0050] The air intake assembly 10 comprises an air inlet 1, a first air bag 2, an air intake passage 3, a second air bag 4, and a one-way air intake member 6. The first air bag 2, the second air bag 4 and the air intake passage 3 are convex.

[0051] The first airbag 2 is configured to admit air from the outside and allow the air to enter the downstream second airbag 4. An air inlet 1 is provided on one side of the first airbag 2, communicating with the outside. An air inlet duct 3 is provided on the other side of the first airbag 2, connecting the first airbag 2 and the second airbag 4, thereby connecting the air inlet duct 3 to the air inlet 1. The first airbag 2 may include an elastic body 21 and an air inlet valve (not shown). In its natural state, the elastic body 21 supports the first airbag 2, allowing gas to enter through the air inlet 1 and fill the first airbag 2. When the first airbag 2 is pressed, the air inlet valve is a one-way valve, preventing gas from leaking out. At this point, due to the pressure differential, the gas in the first airbag 2 enters the second airbag 4 through the air inlet 3. Then, when the first airbag 2 is released, the elastic body 21 elastically resets the first airbag 2, supporting it in its original position. At this point, due to the pressure differential, gas is drawn into the first airbag 2 through the air inlet 1, while the one-way air inlet member 6 prevents gas in the second airbag 4 from being drawn into the first airbag 2. Repeatedly pressing and releasing the first airbag 2 allows the main body 201 to be inflated. It is understood that the elastic body 21 can be made of any elastic material, such as sponge, plastic, spring, rubber, or silicone. Furthermore, any other material that prevents the gas in the first airbag 2 from leaking out can replace the air inlet valve. Furthermore, the elastic body 21 may be replaced with any structure that can supply gas into the first airbag 2 .

[0052] The second airbag 4 is used to ventilate the multiple airbags 205 . As described above, the second airbag 4 is communicatively connected to the first airbag 2 via the air inlet duct 3 , and is communicatively connected to adjacent airbags 205 via at least one air duct 203 .

[0053] The one-way air inlet member 6 is sandwiched between the upper cushion body 207 and the lower cushion body 209 of the impact airbag cushion 200 and is disposed across the second airbag 4, providing a one-way air inlet passage 60 from the first airbag 2 toward the second airbag 4. Opposite ends of the one-way air inlet member 6 are mounted to the second airbag 4. In this embodiment, one end of the one-way air inlet member 6 is mounted to the connection between the first airbag 2 and the second airbag 4 (i.e., the air inlet passage 3), and the other end is mounted to the peripheral edge of the second airbag 4 opposite the first airbag 2 (i.e., the connection between the second airbag 4 and the adjacent and connected airbag 205).

[0054] As shown in Figures 3 and 4 , the one-way air inlet member 6 is composed of two soft, flat films (e.g., plastic sheets), namely, an upper sheet 61 and a lower sheet 62. A one-way air inlet passage 60 is formed between the film-like upper sheet 61 and the film-like lower sheet 62. The upper sheet 61 and the lower sheet 62 are made, for example, of polyether-type TPU, polyester-type TPU (thermoplastic polyurethanes), or PVC, EVA, or other plastic materials. The upper sheet 61 and the lower sheet 62 can be made of the same material or different materials.

[0055] The structure of the one-way air inlet member 6 is shown in FIG3 , for example. The side edges 611 of the upper piece 61 face the side edges 621 of the lower piece 62, and the side edges 613 of the upper piece 61 face the side edges 623 of the lower piece 62, respectively. This is achieved by welding the one-way air inlet member 6 together, for example, to form a structure with three closed sides and one open side 601, which is connected to the interior. Because the upper piece 61 and the lower piece 62 are soft and flat, and particularly because the inner walls of the upper piece 61 and the lower piece 62 where they contact each other are smooth, the upper piece 61 and the lower piece 62 can adhere to each other when in contact, thereby sealing the one-way air inlet passage 60. Furthermore, under the action of an air pressure difference, the one-way air inlet passage 60 can be opened.

[0056] The one-way air inlet member 6, which is closed on three sides and has an opening 601 on one side that communicates with the interior, has a one-way air inlet passage 60 formed inside. The one-way air inlet passage 60 has an air inlet portion 63 at one end communicating with the opening 601 and a fixed portion 67 at the end remote from the opening 601. An air outlet portion 65 is formed between the air inlet portion 63 and the fixed portion 67. The opening 601 of the air inlet portion 63 communicates with the first airbag 2 and the air inlet 1. An air outlet 651 is formed through the air outlet portion 65, communicating with the second airbag 4 and with the opening 601 within the one-way air inlet passage 60. When the one-way air inlet channel 60 is open, the upper piece 61 and the lower piece 62 of the air inlet portion 63 and the air outlet portion 65 are separated, and the air inlet portion 63 and the air outlet portion 65 are connected, so that the opening 601 is connected with the air outlet 651; on the other hand, when the one-way air inlet channel 60 is closed, the upper piece 61 and the lower piece 62 of the air inlet portion 63 and the air outlet portion 65 are adsorbed on each other and are not connected, so that the opening 601 is not connected with the air outlet 651.

[0057] The air inlet 63 is at least arranged in the air inlet passage 3 and is always kept in an open state. It is understood that the air inlet 63 can also be in a closed state, and can be designed according to actual needs.

[0058] The air inlet portion 63 is installed at the connection between the first airbag 2 and the second airbag 4 (that is, at the position of the air inlet passage 3 ), and the opening 601 opens toward the first airbag 2 and communicates with the first airbag 2 .

[0059] The fixing portion 67 is mounted on the periphery of the second airbag 4 that faces the first airbag 2, i.e., the periphery that is away from the first airbag 2. Furthermore, when the periphery of the second airbag 4 that faces the first airbag 2 is connected to the other airbag 205, the fixing portion 67 can be mounted at the connection between the second airbag 4 and the other airbag 205 (i.e., at the location of the air passage 203 between the second airbag 4 and the other airbag 205). The air outlet portion 65 is housed within the second airbag 4, so that the air outlet 651 is suspended in the second airbag 4, thereby smoothly inflating the second airbag 4.

[0060] When the one-way air inlet channel 60 is open, the air outlet 651 is opened, the upper piece 61 and the lower piece 62 at the air outlet 651 are separated, and the gas flows into the second airbag 4 through the air outlet 651. When the one-way air inlet channel 60 is closed, the air outlet 651 is closed due to the contact and adsorption between the upper piece 61 and the lower piece 62. One or more air outlets 651 can be provided, which are composed of dividing lines (such as Figures 5 to 7, etc.), holes (such as Figure 10, etc.) or combinations thereof (Figures 8 and 9) formed on the upper piece 61 and / or the lower piece 62, and the specific shape is not particularly limited. In the case where the air outlet 651 is formed on both the upper piece 61 and the lower piece 62, the air outlet 651 of the upper piece 61 and the lower piece 62 do not necessarily have to overlap or have the same shape.

[0061] In addition, the air outlet portion 65 is also provided with a closing portion 652. The closing portion 652 overlaps with the air outlet 651 by at least a portion, and the upper piece 61 and the lower piece 62 at the closing portion 652 can be combined together, for example, by welding, so that the portion overlapping with the air outlet 651 is closed. Thus, through the closing portion 652, it is possible to avoid the situation where the air outlet 651 cannot be tightly closed due to aging of the material of the one-way air inlet part 6 after being repeatedly closed and opened. The closing portion 652 can be formed into a circle (as shown in Figures 3 and 6), a part of a circle (as shown in Figures 9), a line (as shown in Figures 7 and 8), an irregular shape or a combination thereof, etc., and is not particularly limited here. In addition, it is understandable that the closing portion 652 can also be omitted (as shown in Figure 5).

[0062] The fixing portion 67 is used to secure the one-way air inlet member 6 in a flat position. The fixing portion 67 is the portion of the one-way air inlet member 6 extending from the air outlet portion 65 to the side edges 613 and 623. Typically, the fixing portion 67 overlaps the periphery of the second airbag 4, but is not limited thereto. The fixing portion 67 may be one or more portions of the portion extending from the air outlet portion 65 to the side edges 613 and 623 that are coupled to the upper cushion body 207 and / or lower cushion body 209 of the airbag cushion 200. Furthermore, the side edges 611 and 621 on one or both sides (i.e., the left and / or right sides) of the one-way air inlet passage 60 may be extended to overlap the periphery of the second airbag 4. That is, the fixing portions 67 and the air inlet portion 63 at opposite ends of the one-way air inlet member 6 are fixed to the airbag cushion 200, and the side edges 611 and 621 on one or both sides are also fixed to the airbag cushion 200.

[0063] It is understood that the structure of the one-way air intake member 6 is not limited to being formed by combining the upper piece 61 and the lower piece 62. For example, the one-way air intake member 6 can be composed of an integrated bag-shaped element that is open on one side. Since the one-way air intake member 6 of the bag-shaped element does not need to be combined with the upper piece 61 and the lower piece 62, the combination step is omitted, the process cost is low, and the production efficiency is improved. In addition, it can also be formed by combining along the boundary of the one-way air intake channel 60 of a specific shape (for example, the boundary 603 of Figures 5 to 14). In this case, in the outer area of ​​the boundary 603 of the one-way air intake channel 60, the upper piece 61 and the lower piece 62 can be combined with each other or not, and this is not limited here.

[0064] Specifically, referring to FIG. 5 to FIG. 14 , a case where a boundary 603 is provided to form the one-way air intake passage 60 is described.

[0065] As shown in FIG5 , the boundary 603 can be formed into a "U" shape that surrounds the opening 601 of the air inlet portion 63. Within the boundary 603, a one-way air inlet channel 60, an air inlet portion 63, and an air outlet portion 65 are formed, with a linearly intersecting air outlet 651 shown. The fixing portion 67 is the portion outside the bottom of the "U" shape in the one-way air inlet member 6. By forming the boundary 603 into a "U" shape, the gas flow in the one-way air inlet channel 60 can be more concentrated, making it easier to open the air outlet 651 and thus inflate the air. Furthermore, it is understood that in addition to the fixing portion 67 used to secure the one-way air inlet member 6, the left and / or right portions extending from the boundary 603 to the side edges 611 and 621 can also serve as additional fixing portions to secure the side of the one-way air inlet member 6. It is understood that the shape and fixing position of the left and / or right portions can be arbitrarily set, as long as the side edges of the one-way air inlet member 6 extend beyond the bulge area of ​​the second airbag 4.

[0066] As shown in FIG6 , the only difference between this example and FIG5 is that the shape of the linearly intersecting air outlets 651 is different from that in FIG5 , and a closing portion 652 is formed at the intersection of the air outlets 651 , and the shape of the closing portion 652 is formed into a circle.

[0067] As shown in Figure 7, this example is similar to Figure 6, with the outlines of boundary 603 and the corresponding inlet 63 and outlet 65 modified. The shape of closing portion 652 is also changed to a linear cross. The outline of boundary 603 at inlet 63 gradually narrows as it approaches the center, while the outline at outlet 65 gradually widens as it moves away from the center. Boundary 603 is narrowest in the center. This increases the pressure of gas as it enters through inlet 63, further facilitating the opening of outlet 651 and thus inflation.

[0068] As shown in FIG. 8 , in this example, the air outlet 651 includes a linear first air outlet 6511 and a circular second air outlet 6512 , and the closing portion 652 partially overlaps with the second air outlet 6512 of the air outlet 651 .

[0069] As shown in FIG. 9 , in this example, the air outlet 651 includes a linear first air outlet 6511 and a circular second air outlet 6512 , and the closing portion 652 partially overlaps the first air outlet 6511 and the second air outlet 6512 .

[0070] As shown in FIG. 10 , this example shows a circular air outlet 651 and a linear intersecting closing portion 652 .

[0071] As shown in Figure 11, this example shows an open configuration of the side edges 611 and 621 of the air intake portion 63. This facilitates installation of the air intake portion 63 to the inner wall of the air intake duct 3 and avoids shrinkage of the air intake portion 63 due to thermal installation, which could affect air intake.

[0072] In addition, the present application is not limited to the above-mentioned example in the form of setting the closing portion 652. The closing portion 652 may also not overlap with the air outlet 651 or the first air outlet 6511 and the second air outlet 6512. It only needs to be set around the air outlet 651 or any one of the first air outlet 6511 and the second air outlet 6512 to ensure the closing of the air outlet 651 or the first air outlet 6511 and / or the second air outlet 6512.

[0073] As shown in FIG12 , the inner wall of the air intake portion 63 is coated with an oily anti-adhesion material such as ink or roughened, thereby enabling the opening 601 of the air intake portion 63 to be easily opened even in a closed state.

[0074] As shown in FIG13 , compared to the example in FIG7 , the contour of the air outlet portion 65 at the boundary 603 has a portion that gradually expands as it moves away from the middle portion and extends to the position corresponding to the air outlet 651. This allows the air in the air outlet portion 65 to be more concentrated and filled, increasing the pressure difference near the air outlet 651, making it easier to open the air outlet 651 and thus easier to inflate.

[0075] As shown in FIG14 , the boundary 603 can be a multi-segment boundary, so that the one-way air inlet passage 60 is formed as an air outlet portion 65, and the air outlet 651 is arranged at the two side edges of the one-way air inlet member 6. As a result, the process for forming the air outlet 651 can be omitted. In this case, the closing portion 652 can be arranged at the side edge of the one-way air inlet member 6 so as to overlap with the air outlet 651, or it can be arranged near the air outlet 651 without overlapping with the air outlet 651. In addition, a single closing portion 652 can be provided as needed, or multiple closing portions can be provided. In addition, multiple air outlets 65 can be provided as needed.

[0076] It is understood that the shape of the boundary 603 and the corresponding contours of the air inlet 63 and air outlet 65, and the fixing portion 67 are not limited to the examples described above and can be appropriately modified. The shapes of the air outlet 651 and the closing portion 652 are not limited to the above embodiment and can be appropriately modified.

[0077] The gas outlet assembly 80 includes a third airbag 8 and an outlet port 5, and may also include an outlet valve (not shown). The third airbag 8 is interconnected with each adjacent airbag 205 via at least one air channel 203. Furthermore, the third airbag 8 communicates with the second airbag 4 via a body 201, which connects all airbags 205 and all air channels 203 in series. A one-way outlet valve is installed at the outlet port 5 of the third airbag 8, ensuring one-way gas release.

[0078] The following describes the installation structure of the one-way air inlet member 6 in detail with reference to Figures 15 to 19. It should be noted that Figures 15 to 17 are schematic, partial bottom views of the airbag cushion 200, omitting the lower cushion body 209. Figures 18 and 19 are schematic cross-sectional views of a portion of the airbag cushion 200, illustrating the installation of the air inlet portion 63 in a closed position.

[0079] Figure 15 illustrates an example of the installation configuration of the one-way air inlet member 6. As shown in Figure 15 , the air inlet portion 63 overlaps and is fixed to the air inlet duct 3. The air outlet portion 65 is disposed within the second airbag 4. Furthermore, the fixing portion 67 is fixed to the peripheral edge of the second airbag 4 on a side facing away from the first airbag. As used herein, the peripheral edge of the second airbag 4 refers to the connection between the second airbag 4 and the adjacent airbag. For example, the connection between the second airbag 4 and the first airbag 2 is the air inlet duct 3. The peripheral edge of the second airbag 4 opposite the first airbag 2 is an air duct 203 between the second airbag 4 and an airbag 205 opposite the first airbag 2. By securing the air inlet portion 63 and the fixing portion 67 at both ends of the one-way air inlet member, the one-way air inlet member 6 can be positioned flatly within the cushion 200, thereby allowing the air outlet portion 65 to be flatly accommodated within the second airbag 4. This allows the one-way air inlet member 6 to remain in an unbent position within the second airbag 4, allowing the gas within the one-way air inlet passage 60 to flow unimpeded. The present application utilizes such a one-way air inlet member 6 to prevent slow gas leakage, thereby effectively preventing air leakage from the cushion. Furthermore, frequent inflation is unnecessary, providing ease of use, preventing the one-way air inlet member 6 from curling due to aging, and preventing the poor gas flow, thereby increasing the service life.

[0080] Furthermore, the mounting configuration of the air inlet portion 63 and the fixing portion 67 is not limited to the example described above. As shown in FIG16 , the air inlet portion 63 can be further fixed to the first airbag 2, and the fixing portion can be further fixed to an airbag 205 adjacent to the second airbag 4 and away from the first airbag 2 (shown in the figure as the airbag 205 adjacent to the upper side of the first airbag 2). This allows the one-way air inlet member 6 to remain in an unbent state between the first airbag 2 and the second airbag 4, allowing the gas within the one-way air inlet passage 60 to flow unimpeded. Furthermore, by increasing the width of the opening 601 in the air inlet portion 63, the opening 601 is easier to open, allowing for smoother air intake.

[0081] In the examples shown in Figures 1, 15, and 16 above, the second airbag 4 is used as the mounting airbag for the one-way air inlet member 6, and the opposite ends of the one-way air inlet member 6 are fixed to the second airbag 4. However, the one-way air inlet member 6 can also be mounted on the first airbag 2. An example of using the first airbag 2 as the mounting airbag for the one-way air inlet member 6 will be described below with reference to Figure 17.

[0082] As shown in FIG17 , the opposite ends of the one-way air inlet member 6 are fixed to the first airbag 2, that is, the air inlet portion 63 is fixed to one side of the air inlet port 1 of the mounted airbag, and the fixing portion 67 is fixed to the other side of the mounted airbag away from the air inlet portion 63, that is, the air inlet duct 3. The one-way air inlet member 6 is connected to the outside at the air inlet port 1, thereby allowing external gas to be unidirectionally introduced into the first airbag 2, which serves as the mounted airbag. In addition, the air inlet port 1 can be omitted, so that the opening 601 of the air inlet portion 63 is directly connected to the outside, thereby allowing external gas to be unidirectionally introduced into the first airbag 2, which serves as the mounted airbag. In addition, the air inlet valve (not shown) and the elastic body 21 can be omitted, and external gas can be directly introduced into the one-way air inlet member 6 through an external inflation component.

[0083] In addition, in addition to fixing the air intake portion 63 and the fixing portion 67 to the peripheries on opposite sides of the airbag installation, the one-way air intake member 6 can also have the other sides (i.e., the side edges 611, 621) installed to the other peripheries of the airbag installation. For example, as shown in Figure 17, the side edges 611, 621 on the left side of the one-way air intake member 6 are installed to the periphery of the body 201 that exceeds the bulging area of ​​the first airbag 2 that serves as the airbag installation. It can be understood that the position of the one-way air intake member 6 can be designed according to actual needs. Through the above-mentioned structure of Figure 17, the one-way air intake member 6 can be kept in a non-bent state in the first airbag 2, and the gas in the one-way air intake channel 60 can flow unimpeded.

[0084] In the above installation example, the one-way air inlet member 6 can be attached to the cushion 200 with its opening 601 always open. The following description uses the second airbag 4 as the installation airbag. However, with reasonable modifications, the installation airbag can be replaced with the first airbag 2, and the one-way air inlet member 6 can also be attached to the cushion 200 with its opening 601 always open.

[0085] As shown in Figure 15, the upper piece 61 and the lower piece 62 located at the air intake portion 63 are attached to the positions of the upper cushion body 207 and the lower cushion body 209 of the buffer airbag cushion 200 corresponding to the inner wall of the air intake duct 3, so that the upper piece 61 and the lower piece 62 at the air intake portion 63 are attached to the inner wall of the air intake duct 3, and the upper piece 61 at the air intake portion 63 is also formed to bulge following the bulging shape of the inner wall of the air intake duct 3. Therefore, the air intake portion 63 becomes a ventilation state that is always open and connected to the first airbag 2, thereby avoiding the air intake portion 63 from being closed.

[0086] 16 , so that the upper piece 61 and the lower piece 62 located in the air intake portion 63 are attached to the positions of the inner wall of the upper cushion body 207 and the lower cushion body 209 of the buffer airbag cushion 200 corresponding to at least a portion of the inner wall of the air intake duct 3 and the first airbag 2, so that the upper piece 61 and the lower piece 62 at the air intake portion 63 are attached to the inner wall of at least a portion of the air intake duct 3 and the first airbag 2, so that the upper piece 61 at the air intake portion 63 is formed following the bulging inner wall portion of the first airbag 2 and the air intake duct 3, thereby obtaining a larger opening 601, making the air intake smoother, and even if the upper piece 61 and the lower piece 62 located in the air intake portion 63 sag, shrink, etc. due to subsequent processes or aging, the air intake portion 63 can remain in an open state. As mentioned above, the inner surface of the upper piece 61 located in the air intake portion 63 and the inner wall of the lower piece 62 can also be coated with an anti-sticking material such as ink or the inner wall can be roughened. Thus, even if the upper piece 61 and the lower piece 62 located in the air intake portion 63 sag or shrink due to subsequent processes or aging, the air intake portion 63 can be kept in an open state, and the one-way air intake part 6 can be kept in a non-bent state between the first airbag 2 and the second airbag 4, so that the gas in the one-way air intake channel 60 can flow unimpeded.

[0087] Furthermore, the one-way air inlet member 6 can also be attached to the cushion 200 with its opening 601 closed. The following description uses the second airbag 4 as an example of the mounting airbag. However, if appropriate modifications are made, the mounting airbag can be replaced with the first airbag 2, and the one-way air inlet member 6 can also be attached to the cushion 200 with its opening 601 closed.

[0088] Even when the air inlet portion 63 is fixed to the air inlet duct 3 ( FIG. 15 ) or the air inlet duct 3 and the first airbag 2 ( FIG. 16 ), as long as the opening 601 can be opened under a certain pressure differential and the one-way air inlet function is achieved, the upper sheet 61 near the opening 601 of the air inlet portion 63 need not adhere to the inner wall of the impact airbag cushion 200 corresponding to the air inlet duct 3, thereby maintaining a closed opening 601. In this way, the opening 601 of the air inlet portion 63 can be opened under a pressure differential from the closed state shown in FIG. 18 to the open state shown in FIG. 19 , thereby separating the upper and lower sheets at the one-way air inlet duct 60 and allowing air to flow, thereby enabling one-way air supply to the second airbag 4. In this case, it is preferable that the inner surface of the upper sheet 61 and the inner wall of the lower sheet 62 at the air inlet portion 63 be coated with an anti-adhesion material, such as ink, or roughened to facilitate opening of the opening 601 and facilitate air flow.

[0089] Furthermore, the fixing portion 67 is disposed on the periphery of the second airbag 4 away from the first airbag, sandwiched between the upper cushion body 207 and the lower cushion body 209 of the airbag cushion 200 and bonded to the upper cushion body 207 and the lower cushion body 209. As one example of securing the fixing portion 67, the fixing portion 67 of the one-way air intake member 6 can be first secured to the position of the upper cushion body 207 corresponding to the periphery of the second airbag 4 away from the first airbag, and then the upper cushion body 207 and the lower cushion body 209 can be bonded together. As another example, the fixing portion 67 of the one-way air intake member 6 can be first secured to the position of the lower cushion body 209 corresponding to the periphery of the second airbag 4 away from the first airbag, and then the upper cushion body 207 and the lower cushion body 209 can be bonded together. Furthermore, the process of attaching the one-way air intake member 6 to the lower cushion body 209 is performed simultaneously with the bonding process for forming the side edges 611, 621 and / or the boundary 603 of the upper and lower panels 61 and 62.

[0090] In addition, the multiple airbags 205, the first airbag 2, the second airbag 4, and the third airbag 8 are formed to remain higher than the multiple airways 203 and the air intake duct 3 after the gas is released. This can avoid the user pressing the airway when the airbag is deflated, causing the gas flow inside the buffer airbag cushion 200 to be unsmooth.

[0091] In addition, it can be understood that the multiple air ducts 203 and the air inlet duct 3 can be omitted, and the adjacent airbags among the multiple airbags 205, the first airbag 2, the second airbag 4, and the third airbag 8 are directly connected in series.

[0092] The cushioning airbag pad 200 of the present application is suitable for use on surfaces of backpacks, waist bags, shoulder bags, arm bags, and other bag products that come into contact with people, such as shoulder straps and handles for heavy objects. It is also suitable for use on mattresses, seat cushions, backrests, shoe insoles, and the like. It is beneficial for preventing prolonged pressure on the human body, which can lead to poor blood circulation and pain. Furthermore, the contact areas are airtight, prone to sweating and unable to effectively dissipate heat, causing significant discomfort, affecting skin health, and potentially posing health risks. The cushioning airbag pad 200 of the present application can cushion and relieve pressure on the contact areas of the human body, and the gaps between the airbags provide a good channel for heat dissipation.

[0093] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
