[0038] Example 1

[0039] As mentioned in the background technology, in order to solve the problems in the prior art, this embodiment provides a low-noise massage air bag for a car seat, comprising:

[0040] At least two sub-air bag bodies 1 are stacked along a first direction, each sub-air bag body 1 including an upper sealing film 11 and a lower sealing film 12. The edges of the upper sealing film 11 and the lower sealing film 12 are sealed together. At least one sub-air bag body 1 is provided with a gas exchange port for exchanging gas with the gas supply assembly. The sub-air bag bodies 1 are connected by a gas channel and are inflated and deflated through the gas exchange port to switch between an inflated state and a deflated state.

[0041] The noise reduction member includes a first noise reduction member arranged inside the sub-air bag body 1 and / or a second noise reduction member arranged between adjacent sub-air bag bodies 1. The noise reduction member is used to prevent the upper sealing film 11 and the lower sealing film 12 of the sub-air bag body 1 from being sucked together when the sub-air bag body 1 is in a deflated state.

[0042] like Figure 1 and Figure 10 As shown, the first direction is Figure 1In the vertical direction of the airbag, the two sub-air bag bodies 1 are stacked along a first direction, and a gas exchange port is opened at the edge of one of the sub-air bag bodies 1, which is connected to an external air source through an air pipe 4, thereby inflating / deflating the massage air bag. The gas channel is used to connect the interior of the two sub-air bag bodies 1, and then the two sub-air bag bodies 1 can be inflated / deflated in turn through the gas exchange port; the first noise reduction body is arranged inside the sub-air bag body 1, between the upper sealing film 11 and the lower sealing film 12, which can prevent the upper sealing film 11 and the lower sealing film 12 from being attracted to each other when the sub-air bag body 1 is in a deflated state; a second noise reduction body can also be arranged between the upper sealing film 11 and the lower sealing film 12 of the adjacent sub-air bag body 1. When the sub-air bag body 1 is deflated, the deformation of the upper sealing film 11 and the lower sealing film 12 fixed to the second noise reduction body is limited by the second noise reduction body and cannot be restored to the initial state without external force, which can also prevent the upper sealing film 11 and the lower sealing film 12 from being attracted to each other; Figure 4 and Figure 7 As shown, in other embodiments of the present application, three sub-air bag bodies 1 can be provided, and the three sub-air bag bodies 1 can be respectively provided with a first noise reduction body, or partially provided with the first noise reduction body, and a second noise reduction body can be provided between adjacent sub-air bag bodies. According to actual conditions, the first noise reduction body can be provided in the sub-air bag body 1 or the second noise reduction body can be provided between adjacent sub-air bag bodies 1, and the first noise reduction body and the second noise reduction body can be provided at the same time.

[0043] By setting up the noise reduction component, the noise reduction component can prevent the upper sealing film 11 and the lower sealing film 12 of the sub-air bag body 1 from adhering to each other after the sub-air bag body 1 is emptied of gas, effectively avoiding the air popping sound generated during inflation and improving the experience of the seat comfort system.

[0044] In a preferred embodiment, the first noise reduction body is a flexible breathable member 2 , and the flexible breathable member 2 is disposed in at least one sub-air bag body 1 .

[0045] like Figure 1-3 As shown, in this embodiment, two sub-air bag bodies 1 are provided, and flexible breathable members 2 are provided in the two sub-air bag bodies 1. The flexible breathable member 2 is made of sound-absorbing sponge. The sound-absorbing sponge has a porous structure and has good sound insulation effect and breathability. The sound-absorbing sponge can prevent the upper sealing film 11 and the lower sealing film 12 of the sub-air bag body 1 from sticking together after the massage air bag is deflated. At the same time, the porous structure can stabilize the airflow during inflation to prevent the generation of air popping sound; Figure 4-9 As shown, three sub-air bag bodies 1 may be provided, and the three sub-air bag bodies 1 may all be provided with flexible breathable members 2, or may be partially provided with flexible breathable members 2.

[0046] In a preferred embodiment, when the sub-air bag body 1 is in a deflated state, the upper sealing film 11 and the lower sealing film 12 are respectively attached to both sides of the flexible breathable member 2 along the first direction; when the sub-air bag body 1 is in an inflated state, the flexible breathable member 2 is fixed on the upper sealing film 11 / lower sealing film 12 and separated from the lower sealing film 12 / upper sealing film 11.

[0047] In a preferred embodiment, through holes 13 are respectively opened on the upper sealing film 11 / lower sealing film 12 and the lower sealing film 12 / upper sealing film 11 of two adjacent sub-airbag bodies 1, and two adjacent through holes 13 are connected to form a gas channel.

[0048] like Figure 1-3 As shown, in this embodiment, two through holes 13 are respectively opened on the lower sealing film 12 of the upper child air bag body 1 and the upper sealing film 11 of the lower child air bag body 1. The outer peripheries of the through holes 13 on the lower sealing film 12 and the upper sealing film 11 are welded to each other so that the two sealing films form a telescopic layer; Figure 4-9 As shown, in other embodiments of the present application, when three sub-air bag bodies 1 are provided, a through hole 13 is provided on the lower sealing film 12 of the sub-air bag body 1 located at the top, a through hole 13 is provided on the upper sealing film 11 and the lower sealing film 12 of the sub-air bag body 1 located in the middle, and a through hole 13 is provided on the upper sealing film 11 of the sub-air bag body 1 located at the bottom; when the sub-air bag body 1 is in a deflated state, the upper sealing film 11 and the lower sealing film 12 are in a natural state, and the flexible breathable member 2 is located between the upper sealing film 11 and the lower sealing film 12 to prevent the upper sealing film 11 and the lower sealing film 12 from leaking. They adhere to each other, thereby preventing the two sealing films from suddenly opening when inflated and producing an air popping sound; when the sub-air bag body 1 is inflated, the upper sealing film 11 and the lower sealing film 12 are in a stretched state, and the flexible air-permeable member 2 in the upper sub-air bag body 1 is fixed on the lower sealing film 12, and the flexible air-permeable member 2 in the lower sub-air bag body 1 is fixed on the upper sealing film 11. When three sub-air bags 1 are provided, the flexible air-permeable member 2 in the middle sub-air bag body 1 is fixed on the upper sealing film 11 / lower sealing film 12, or the middle sub-air bag body 1 does not have a flexible air-permeable member 2.

[0049] In a preferred embodiment, the second noise reduction body is a limiter 3, and the number of the limiter 3 is at least one. The limiter 3 is arranged between the upper sealing film 11 / lower sealing film 12 and the lower sealing film 12 / upper sealing film 11 of two adjacent sub-air bag bodies 1 that are close to each other, and the gas channel is located inside the limiter 3.

[0050] like Figure 10-12As shown, the limiting member 3 can be a gasket or a gasket with a connecting hole opened in the center position. The limiting member 3 is sleeved outside the gas channel and fixed to the lower sealing film 12 and the upper sealing film 11 close to each other of the two adjacent sub-air bag bodies 1. After the massage air bag is deflated, the limiting member 3 can limit the deformation of the upper sealing film 11 and the lower sealing film 12 respectively, so that the upper sealing film 11 and the lower sealing film 12 cannot restore their original shapes, that is, there is a gap in the sub-air bag body 1 after deflation, which can avoid mutual adsorption between the sealing films during use, that is, during the repeated inflation / deflation process of the massage air bag.

[0051] In a preferred embodiment, the flexible gas-permeable member 2 covers one side of the gas channel along the first direction.

[0052] In a preferred embodiment, the projections of at least two flexible air-permeable members 2 in the first direction completely overlap.

[0053] like Figure 13 and Figure 14 As shown, the multiple flexible breathable members 2 have the same shape and size, and their positions correspond to each other, that is, their projections in the first direction completely overlap; the flexible breathable member 2 in the upper sub-air bag body 1 is fixed on the lower sealing film 12 and completely covers the through hole 13 on the lower sealing film 12, and the flexible breathable member 2 in the lower sub-air bag body 1 is fixed on the upper sealing film 11 and completely covers the through hole 13 on the upper sealing film 11. When three sub-air bag bodies 1 are provided, the flexible breathable member 2 in the middle sub-air bag body 1 is fixed on the upper sealing film 11 / lower sealing film 12 and completely covers the through hole 13 on the upper sealing film 11 / lower sealing film 12; when the massage air bag is inflated, the gas enters the lower sub-air bag body 1 from the gas exchange port, the lower sub-air bag body 1 expands, and at the same time, the gas passes through the flexible breathable member 2 inside it and enters the second sub-air bag body adjacent to it through the gas channel. When the air in the bag is inflated, the air in the bag 1 is released, and the air in the bag 1 is inflated, thereby opening the three sub-bags 1 in sequence.

[0054] In a preferred embodiment, the flexible gas-permeable member 2 is attached to one side of the gas channel along the first direction and does not completely cover the gas channel.

[0055] In a preferred embodiment, the projections of the two flexible air-permeable members 2 in the first direction completely overlap or completely do not overlap.

[0056] like Figure 13 and Figure 15 As shown, the two flexible breathable members 2 have the same shape and size. When the massage air bag is inflated, the gas enters the lower sub-air bag body 1 from the gas exchange port, and the lower sub-air bag body 1 expands. If the projections of the two flexible breathable members 2 in the first direction completely overlap, a portion of the gas passes through the flexible breathable member 2 in the lower sub-air bag body 1 and then passes through the flexible breathable member 2 in the upper sub-air bag body 1 through the gas channel to enter the upper sub-air bag body 1, and the other portion of the gas passes through the gas channel and directly enters the upper sub-air bag body 1, so that the upper sub-air bag body 1 is inflated and expanded, and then the two sub-air bag bodies 1 are opened in sequence; if the projections of the two flexible air-permeable members 2 in the first direction do not overlap at all, a part of the gas passes through the flexible air-permeable member 2 in the lower sub-air bag body 1 and enters the upper sub-air bag body 1 through the gas channel, and the other part of the gas passes through the flexible air-permeable member 2 in the upper sub-air bag body 1 and enters the upper sub-air bag body 1 through the gas channel, so that the upper sub-air bag body 1 is inflated and expanded, and then the two sub-air bag bodies 1 are opened in sequence.

[0057] In other embodiments of the present application, the flexible breathable member 2 is not limited to the above-mentioned setting method and can be modified according to actual needs to ensure that after the massage air bag is deflated, the flexible breathable member 2 can separate the upper sealing film 11 and the lower sealing film 12 of the sub-air bag body 1 in which it is located.

[0058] Example 2

[0059] This embodiment provides a car seat, comprising at least one low-noise massage air bag for the car seat as described in Example 1.

[0060] like Figure 16 As shown, the car seat also includes a seat cover 5 and foam 7. The foam 7 is arranged on the seat frame. Several massage air bags are arranged between the foam 7 and the seat cover 5. The foam 7 is provided with grooves matching the outer contours of the several massage air bags for placing the massage air bags. In other embodiments of the present application, a comfort sponge 6 can be added between the seat cover 5 and the massage air bags to further improve the comfort of the car seat.
