[0032] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0033] like Figures 1 to 7 As shown, an airbag assembly of this embodiment includes: multiple airbags 10, each airbag 10 including multiple stacked sub-airbags 11 and a connecting portion 12. The connecting portion 12 is provided between adjacent sub-airbags 11 to connect the sub-airbags 11. When the airbag assembly is placed horizontally, the projections of adjacent airbags 10 on the horizontal plane have overlapping portions. The airbag assembly extends from a first side of the airbag 10 to a second side of the airbag 10. An object is placed at the bottom of the airbag assembly, and the sub-airbags 11 at the bottom are connected to the object.

[0034] In the technical solution of this embodiment, each airbag 10 of the airbag assembly is composed of multiple stacked sub-airbags 11. This allows the operating height of the airbag 10 to be increased without increasing the diameter of the airbag. This structure effectively meets the human body's need for a certain height within a certain area. An object is positioned at the bottom of the airbag assembly, and the sub-airbags 11 at the bottom are connected to the object, effectively securing the airbag 10 and the bottom object 100, making them less susceptible to dislocation under external forces. The technical solution of this embodiment effectively solves the problem of airbag assemblies in the prior art that are prone to dislocation under external forces.

[0035] It should be noted that the bottom airbag 11 of this embodiment is fixedly connected to the object 100, and the airbags 10 are stacked in the thickness direction of the bedding. In this embodiment, the stacking is upward. The connecting portion has a predetermined extension distance in the thickness direction of the bedding, which facilitates the arrangement and combination of the airbags when used in combination, for example, multiple airbags can be clamped together. The airbags of this embodiment are not simply stacked. Instead, the airbags and the connecting portion 12 are integrally formed, or they are connected and fixed by bonding, riveting, sewing, welding, or other methods. When the airbags are inflated, the height of the first side of the airbag is greater than the height of the second side. This facilitates subsequent combination and configuration, such as stacking multiple airbags or clamping them together. This combination of airbags can improve human comfort and provide greater flexibility, meeting the needs of people of different weights, genders, and heights. The height of the first side of the airbag can be greater than the height of the second side in various ways, such as by having the second airbag tilt upward. The length of the first side of the connecting portion 12 is greater than the length of the second side of the connecting portion 12. The first side of the connecting portion 12 is consistent with the first side of the airbag, and the second side of the connecting portion 12 is consistent with the second side of the airbag. There are many ways to achieve that the height of the first side of the airbag is greater than the height of the second side of the airbag. In this embodiment, the length of the first side of the connecting portion 12 is greater than the length of the second side of the connecting portion 12 to meet the requirement that the height of the first side of the airbag is greater than the height of the second side of the airbag. This structure facilitates the combination of multiple airbags, for example, placing the airbag in the gap between the sub-airbags. The first side of the connecting portion 12 here specifically refers to the front of the connecting portion 12, and the second side of the connecting portion 12 specifically refers to the rear of the connecting portion 12. The distance from the front of the connecting portion 12 to the rear of the connecting portion 12 decreases linearly. As those skilled in the art will understand, when the number of the multiple sub-airbags is two, there is one connecting portion 12; when the number of the multiple sub-airbags is three, there are two connecting portions 12; when the number of the multiple sub-airbags is four, there are three connecting portions 12, and so on. No further details will be given here. The airbags of the airbag assembly are flush in the left and right directions, and extend in a step-like manner in the front and back positions.

[0036] The distance between the connecting portion 12 and the first side of the airbag is greater than or equal to the distance between the connecting portion 12 and the second side of the airbag. Such a structure allows a larger fitting area when multiple airbags are combined, and the fitting between the airbags is stable. The length from the connecting portion 12 to the second side of the airbag accounts for 1 / 8 to 1 / 2 of the length from the first side of the airbag to the second side of the airbag. Such airbags fit more stably when combined, for example, when the airbags are clamped, the fitting area is larger. As a more preferred embodiment, the length from the connecting portion 12 to the second side of the airbag accounts for 1 / 4 to 1 / 3 of the length from the first side of the airbag to the second side of the airbag. The height of the first side of the connecting portion 12 is greater than the height of the second side of the connecting portion 12, and the height of the connecting portion 12 changes continuously.

[0037] like Figure 3 and Figure 4 As shown, in the technical solution of this embodiment, the object 100 includes an airbag connecting layer, and the sub-airbags 11 at the bottom of the airbag 10 are connected to the airbag connecting layer. The airbag connecting layer improves the integrity, stability and consistency of the airbag assembly. The airbag connecting layer is connected to at least part of the airbags 10 of the airbag assembly. In this embodiment, the airbag connecting layer is connected to all the airbags 10, as shown in FIG. Figure 3 As shown in , the airbag connection layer comprises two airbag connection straps, one located on either side of the bottom of the airbag assembly, and each airbag connection strap is sequentially connected to each airbag 10. Alternatively, each airbag connection strap may be connected to an airbag 10 at each end of the airbag assembly, and the airbags 10 in the middle of the airbag assembly may be connected in a skipping manner, i.e., some airbags 10 in the middle of the airbag assembly may be connected to the airbag connection straps while others may not. The sub-airbags in the same airbag are bonded together or integrally formed, rather than simply placing the upper sub-airbag on the lower sub-airbag.

[0038] In the technical solution of this embodiment, the airbag 11 is connected to the airbag connecting layer by riveting, tying, sewing or gluing, which are all possible. Figure 4 As shown, the sub-airbag 11 is connected to the airbag connecting layer by welding. The airbag is formed by welding TPU or rubber material using high-frequency equipment to melt the material. In this embodiment, the bottom support material is replaced with the same material as the airbag fabric. In this way, the airbag and the bottom support airbag fabric material (airbag connecting layer) can be connected by high-frequency welding, which is very stable and reliable.

[0039] like Figure 3As shown, in the technical solution of this embodiment, the airbag connecting layer is flat and extends in the direction of the airbag assembly. This flat shape ensures a comfortable feel and prevents unevenness in the mattress caused by the airbag connecting layer. The airbag connecting layer extends in the direction of the airbag assembly, ensuring that it can connect to all airbags in the airbag assembly.

[0040] like Figure 3 As shown, in the technical solution of this embodiment, the airbag connecting layer includes a plurality of airbag connecting belts, each of which is arranged at intervals, and each of which extends along the extension direction of the airbag assembly. The provision of a plurality of airbag connecting belts ensures that the force on the airbag assembly is more balanced and stable, and the service life is longer. As other embodiments, the airbag connecting layer is a closed rectangle or the airbag connecting layer is a rectangle with a hollow structure. It should be noted that the rectangle of the present application can be a similar rectangle, for example, a rectangle with four chamfers. It is also possible for the rectangle to be extended to other shapes, such as an ellipse. The airbag connecting layer is a rectangle with a hollow structure. The airbag assembly of such a structure saves more material and is lighter in weight. It should be noted that the hollow structure can be in various forms, for example, a large rectangle with a hollowed-out middle portion, so that the airbag connecting layer is in the shape of a U-shaped rectangle.

[0041] In the technical solution of this embodiment, the airbag connection layer comprises an elastic material, a rigid material, or a flexible material. Elastic materials include rubber and silicone, rigid materials include wood, and flexible materials include cloth. The airbag connection layer can also be a combination of two or three of these materials.

[0042] like Figure 5 and Figure 6 As shown in another embodiment, object 100 comprises a mattress support layer, with air cells 11 connected to the support layer via riveting, cable ties, sewing, or gluing. The figure shows a structure connected using rivets 20. The rivets here are not necessarily made of metal and can be made of rubber, silicone, or other materials. Rivets 20 pass through connecting holes 111 in the bottom of the air cells to connect to the support layer.

[0043] like Figure 3 and Figure 5 As shown, in the technical solution of this embodiment, each air bag 10 is stacked. When each air bag is stacked, as shown in FIG. Figure 3 and Figure 5As shown, in this embodiment, the stacking of the airbags is such that each airbag extends in a staggered manner in the left and right directions in sequence, forming a step-like structure, and the front and rear sides of each airbag are aligned. Such a regular arrangement not only ensures consistent processing standards for the airbags 10, but also ensures consistent human sensation, resulting in better comfort. As another embodiment, the connecting portion 12 has a predetermined length, which can facilitate the arrangement of the airbag clamping structure, that is, the clamping cooperation of adjacent airbags 10. The sub-airbags in the airbag are bonded together or integrally formed, rather than simply placing the upper sub-airbag on the lower sub-airbag.

[0044] like Figure 1 and Figure 2 As shown, in the technical solution of this embodiment, each airbag 10 includes a first sub-airbag, a second sub-airbag, and a connecting portion 12 of predetermined length. The connecting portion 12 is located between the first sub-airbag and the second sub-airbag to connect the first sub-airbag and the second sub-airbag. The first sub-airbag is connected to the object 100. The airbag 10 with the above structure has a higher pushing height when the plane area is the same.

[0045] In the technical solution of this embodiment, the second sub-airbag is connected to the adjacent airbag 10 so that it can move relative to each other. This greatly reduces the forces acting between the airbags 10. The second sub-airbag and the adjacent airbag 10 are relatively movable, so the second sub-airbag and the adjacent airbag 10 can move in conjunction with each other in both the inflated and non-inflated states.

[0046] Each second sub-airbag has a connecting through-hole, and the connecting member passes through the connecting through-hole. The provision of the connecting through-hole makes connection convenient, operation simple, and the provision cost low. It should be noted that each sub-airbag in this embodiment includes a sub-airbag main body and a skirt located at the edge of each sub-airbag, and the connecting through-hole is arranged at the skirt position, so as not to cause damage to each sub-airbag. The connecting through-hole is located on the second side of the second sub-airbag. The connecting through-hole is located on the skirt of the second side of the second sub-airbag, which facilitates the connection of the second sub-airbag. There are multiple connecting through-holes on each second sub-airbag, and the multiple connecting through-holes are arranged on both sides of the direction from the first side of the airbag 10 to the second side of the airbag 10. Such a structure facilitates the connection of adjacent second sub-airbags, so that the force on the airbag 10 is balanced. The multiple connecting through-holes are respectively located on both sides along the extension direction of the airbag assembly, so that the connecting through-holes are located on the side of the second sub-airbag. Such a structure prevents the airbag 10 from being lifted or misplaced from the edge position. Each second sub-airbag also has a matching through-hole, and the connecting member passes through the connecting through-hole and the matching through-hole to connect each second sub-airbag. The matching form of the connecting through-hole and the matching through-hole makes the connection between each second sub-airbag more convenient. There are multiple matching through-holes, and the multiple matching through-holes are respectively located between the first side of the airbag 10 and the second side of the airbag 10, and are located on both sides of the extension direction from the first side of the airbag 10 to the second side of the airbag 10. This makes the matching of the matching through-hole and the connecting through-hole more convenient, and the matching through-hole and the connecting through-hole will not damage the airbag body. There are multiple matching through-holes on each side. In this way, the connection position of two adjacent second sub-airbags can be adjusted as needed to ensure that the adjacent airbags 10 are in the best matching state. When the connecting member is a rivet, the connecting through-hole is a long hole extending in the direction from the first side of the airbag 10 to the second side of the airbag 10. The connecting through hole is a long hole extending from the first side of the airbag 10 to the second side of the airbag 10, so that adjacent second sub-airbags can move relative to each other along the direction from the first side of the airbag 10 to the second side of the airbag 10 and form a limit in other directions.

[0047] The present application also provides a mattress. The mattress includes an airbag assembly, which is the airbag assembly described above. The airbag assembly of such a mattress is less likely to be misaligned.

[0048] The present application also provides a bed, which includes a mattress, which is the above-mentioned mattress.
