[0027] In order to facilitate the understanding of the present invention, the present invention is described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is described as "fixed to" another element, it can be directly on the other element, or there can be one or more centered elements therebetween. When an element is described as "connected to" another element, it can be directly connected to the other element, or there can be one or more centered elements therebetween. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this specification are for illustrative purposes only.

[0028] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in this specification and in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used in this specification includes any and all combinations of one or more of the related listed items.

[0029] In the prior art, the airbag used to support the human buttocks is usually an integral airbag. The human buttocks sit on the integral airbag. Under the weight of the human body, the integral airbag is squeezed in the height direction, causing the height of the integral airbag to decrease, that is, the height deformation of the integral airbag is large, and the horizontal direction of the integral airbag is deformed outward, thereby affecting the overall height of the integral airbag. Not only is the integral airbag prone to shrinkage and wrinkles, but the contact area between the integral airbag and the human buttocks is large, which is not convenient for the heat dissipation of the human buttocks and easily causes heat accumulation, resulting in a poor user experience.

[0030] The present invention provides an air bag assembly 100, see Figure 1-Figure 3 The airbag assembly 100 includes a cushion body 10 and a plurality of support airbags 20, and the plurality of support airbags 20 are arranged in an array on the cushion body 10. The cushion body 10 is used to be installed on an external device, such as a seat, a pneumatic comfort system or a massage device, etc. The cushion body 10 provides support for the plurality of support airbags 20, and the support airbags 20 are connected to the air source of the external device. The air source of the external device can inflate the support airbags 20 to expand the support airbags 20. When the air source of the external device draws the gas of the support airbags 20, or the support airbags 20 deflate to the outside, the support airbags 20 are deflated. The support airbags 20 are used to carry external objects, such as the airbag assembly 100 is installed on the massage device, and the human body sits on the support airbags 20, that is, the buttocks of the human body sit on the support airbags 20. The softness and hardness of the support airbags 20 are adjusted by the deflation or expansion of the support airbags 20, thereby further providing the user with a softness and hardness adjustment function.

[0031] In addition, there is a gap 100a between any two adjacent air bags, and the gap 100a is connected to the outside world. The gap 100a is used for ventilation, which facilitates the circulation of air, thereby increasing the air permeability between the external object and the support air bag. When the support air bag 20 carries an external object, part of the external object is located in the gap 100a, and the gap 100a is conducive to heat dissipation. For example: the support air bag 20 carries the buttocks of a human body, especially in the hot summer, the gap 100a can increase the air permeability between the external object and the support air bag.

[0032] The cushion body 10 is a plate-like structure and is provided with a plurality of ventilation holes 10a, which penetrate the cushion body 10 through the gap 100a so that the ventilation holes 10a are connected to the gap 100a, and the ventilation holes 10a can increase the air permeability of the airbag assembly 100 so that the airbag assembly 100 has good ventilation performance.

[0033] Any two supporting air bags 20 are connected to each other so that the multiple supporting air bags 20 are expanded or deflated at the same time, so that the softness and hardness of the supporting air bags 20 are evenly adjusted. Specifically, any two adjacent supporting air bags 20 are connected through a connecting channel 100b, for example, they are connected through a hollow pipe, that is, one end of the hollow pipe is connected to the first air cavity 20a of one supporting air bag 20, and the other end of the hollow pipe is connected to the first air cavity 20a of another supporting air bag 20. For another example, the connecting channel 100b is provided on the cushion body 10.

[0034] For the above-mentioned support airbag 20, please refer to Figure 4 The support air bag 20 includes a first bag body 21 and a first elastic filler 22. The first bag body 21 is provided with a first air groove 21a, the cushion body 10 covers and is enclosed in the first air groove 21a, the first air groove 21a and the cushion body 10 are enclosed together to form a first air cavity 20a, and the first elastic filler 22 is filled in the first air cavity 20a. When the hardness of the support air bag 20 needs to be adjusted, the first air cavity 20a is inflated or the gas in the first air cavity 20a is sucked through the air source. When the air source sucks a preset amount of gas from the first air cavity 20a, the first air groove portion 21a contacts the first elastic filling piece 22. When the inner wall of the first bag body 21 continues to squeeze the first elastic filling piece 22, the first elastic filling piece 22 supports the inner wall of the first bag body 21, the first elastic filling piece 22 undergoes elastic deformation, and the first elastic filling piece 22 generates an elastic force to resist the wrinkles of the inner wall of the first bag body 21. When the air source inflates the first air cavity 20a, the support air bag 20 gradually changes from a deflated state to an expanded state, and the inner wall of the first bag body 21 gradually moves away from the first elastic filling piece 22. The first elastic filling piece 22 gradually resets under the action of its own elastic force until the inner wall of the first bag body 21 is separated from the first elastic filling piece 22.

[0035] The first elastic filler 22 is made of a sponge pad or a thermoplastic elastomer. The sponge pad and the thermoplastic elastomer have good elastic force when bearing an external object of a preset weight, are not prone to permanent deformation, and will not cause damage to the external object. For example, bearing the weight of a human body. In addition, the first elastic filler 22 has a plurality of hollow holes, so that the first elastic filler 22 forms a grid structure. When pressure is applied to the first elastic filler 22, the first elastic filler 22 has a larger deformation distance, so that the first elastic filler 22 has better elastic force.

[0036] Optionally, the first elastic filling member 22 may also be other elastic objects, such as silica gel, rubber, etc.

[0037] In some embodiments, see Figure 5The air bag assembly 100 includes a plurality of massage air bags 30, which are arranged on the cushion body 10, and the air source is connected to the massage air bags 30, and the massage air bags 30 are inflated or sucked by the air source, so as to achieve massage or tapping. For example, the massage air bags 30 are quickly inflated and sucked by the air source, so as to achieve vibration massage. The plurality of massage air bags 30 and the plurality of support air bags 20 are arranged in an array on the cushion body 10, and there is a gap 100a between two adjacent air bags. When an external object contacts the massage air bags 30 and the support air bags 20, the contact area between the external object and the massage air bags 30 and the support air bags 20 is reduced, and the contact area between the external object and the massage air bags 30 and the support air bags 20 is increased. Any two massage air bags 30 are isolated from each other. It can be understood that any two massage air bags 30 are not connected. The gas is distributed to the plurality of massage air bags 30 by the gas distribution device, so that a single massage air bag 30 can also massage or tap.

[0038] In some embodiments, any one massage airbag 30 is adjacent to at least two massage airbags 30 and forms a massage area, and there is a gap 100a between two adjacent massage airbags 30. For example, three massage airbags 30 are located in one massage area and arranged in a herringbone shape, or four massage airbags 30 are located in one massage area and arranged in a herringbone shape. There is a gap 100a between two adjacent massage airbags 30 to reduce the contact area between the external object and the massage airbag 30 and increase the ventilation between the external object and the massage airbag 30.

[0039] In some other embodiments, there are at least two massage areas, and the at least two massage areas are spaced apart and distributed at different positions of the cushion body 10 to achieve different massage effects. For example, when there are two massage areas, the massage air bags 30 in the two massage areas are inflated or deflated, and the massage air bags 30 in one massage area extend or shrink toward the massage air bags 30 in another massage area, or the massage air bags 30 in another massage area extend or shrink toward the massage air bags 30 in one massage area, thereby achieving kneading massage.

[0040] In some embodiments, the massage airbag 30 includes a second bag body (not shown) and a second elastic filler (not shown). The second bag body is provided with a second air groove portion, the cushion body 10 covers and is enclosed in the second air groove portion, the second air groove portion and the cushion body 10 are enclosed together to form a second air cavity, the second elastic filler is filled in the second air cavity, and the second air cavity is inflated or the gas in the second air cavity is sucked by the air source, so as to adjust the hardness of the massage airbag 30. The massage airbag 30 is usually in an expanded state, and the surface of the expanded massage airbag 30 is smooth, which increases the appearance. When the air source draws air from the second air cavity, the second air groove contacts the second elastic filling piece. When the inner wall of the second bag body continues to squeeze the second elastic filling piece, the second elastic filling piece supports the inner wall of the second bag body, the second elastic filling piece undergoes elastic deformation, and the second elastic filling piece generates an elastic force to resist the wrinkles of the inner wall of the second bag body. When the air source inflates the second air cavity, the massage air bag 30 gradually changes from a deflated state to an expanded state, the inner wall of the second bag body gradually moves away from the second elastic filling piece, and the second elastic filling piece gradually resets under the action of its own elastic force until the inner wall of the second bag body is separated from the second elastic filling piece.

[0041] The second elastic filler is made of a sponge pad or a thermoplastic elastomer. In addition, the second elastic filler has a plurality of hollow holes, so that the second elastic filler forms a grid structure, and when pressure is applied to the second elastic filler, the second elastic filler has a larger deformation distance, so that the second elastic filler has better elastic force.

[0042] Optionally, the second elastic filling piece may also be other elastic objects, such as silica gel, rubber, etc.

[0043] It should be noted that the manufacturing of the airbag assembly 100 is described in detail below:

[0044] See also Figure 6 A first sheet material 40 is provided, and the first sheet material 40 has a first surface 40a and a second surface 50b that are arranged opposite to each other. An air groove portion is formed by the first surface 40a of the first sheet material 40 being recessed toward the second surface 50b, so that the first sheet material 40 forms a bag body, for example, a first bag body 21 and a second bag body are formed. In addition, a connecting groove portion is formed by the first sheet material 40 being recessed along the first surface 40a toward the second surface 50b, and the connecting groove portion is connected to the air groove portion. A second sheet material 50 is provided, and the second sheet material 50 is respectively sealed in the air groove portion and the connecting groove portion, so that the first sheet material 40 is fixedly connected to the second sheet material 50, and the second sheet material 50 and the air groove portion are enclosed together to form an air cavity, and the second sheet material 50 and the connecting portion are enclosed together to form a connecting channel 100b, and the connecting channel 100b is connected to the air cavity.

[0045] In an embodiment of the present application, an airbag assembly 100 is provided, which includes a cushion body 10 and a plurality of support airbags 20, wherein the plurality of support airbags 20 are arranged in an array on the cushion body 10, and a gap 100a is provided between two adjacent support airbags 20, and the support airbag 20 includes a first bag body 21 and a first elastic filling member 22; the first bag body 21 and the cushion body 10 together enclose a first air cavity 20a, the first elastic filling member 22 is located in the first air cavity 20a, the first air cavities 20a of two adjacent support airbags 20 are connected to each other, and the first air cavity 20a is used to connect to an external gas source through a gas distribution device. The support air bag 20 is inflated or deflated through an air source to adjust the hardness of the air bag assembly 100. When the support air bag 20 is deflated until the inner wall of the support air bag 20 contacts the first elastic filling piece 22, the first elastic filling piece 22 can support the inner wall of the air bag 20 to resist deformation of the support air bag, thereby reducing the risk of excessive height change of the air bag assembly 100. When an external object acts on the air bag assembly 100 so that the inner wall of the support air bag 20 presses the first elastic filling piece 22, the first elastic filling piece 22 is elastically deformed and generates an elastic force. The elastic force of the first elastic filling piece 22 can resist the pressure of the support air bag 20, thereby achieving the effect of the air bag assembly 100 to cushion external objects.
