[0054] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0055] Please refer to Figure 7 The utility model provides a pneumatic adjustment device for a car seat, comprising:

[0056] At least one air bag assembly 10, wherein the air bag assembly 10 is arranged on one side of the foam 1;

[0057] A limiting mechanism, the limiting mechanism is arranged on the side of the foam 1 away from the occupant;

[0058] An air source component is arranged on the side of the limiting mechanism away from the foaming 1, and is connected to the air bag component 10 through the first air pipe 6, and is used to inflate the air bag component 10; the first air pipe 6 passes through the limiting mechanism, and the limiting mechanism is used to constrain the position of the first air pipe 6.

[0059] Specifically, refer to Fig.17 The airbag assembly 10 includes a mounting member 3 and an airbag 4 .

[0060] The air bag assembly 10 and the limiting mechanism can be respectively arranged on both sides of the foam 1, and can be arranged on the same side.

[0061] The foam 1 has a mounting seam 21 , and both ends of the mounting member 3 have a T-shaped structure 12 . The mounting member 3 is connected to the foam 1 by snapping the T-shaped structure 12 into the mounting seam 21 .

[0062] In some cases, the mounting member 3 may be connected to the airbag 4 by welding or pasting. In other cases, the airbag 4 may be connected to the foam 1 by rivets, buckles or hooks.

[0063] The first air pipe 6 passes through the first through hole 2 on the foam 1 and the limiting mechanism, one end of the first air pipe is connected to the air bag 4, and the other end of the first air pipe is connected to the air source component.

[0064] When the gas source assembly intermittently fills the air bag 4 with gas through the first air pipe, the limiting mechanism and the first through hole 2 abut against the first air pipe 6 at the same time, and together restrain the first air pipe to achieve the effect of reducing noise.

[0065] In one case, the limiting mechanism abuts against a part of the outer surface of the first air pipe 6 in the circumferential direction. In another case, the limiting mechanism abuts against the entire outer surface of the first air pipe 6 in the circumferential direction.

[0066] Specifically, the support plate 5 is a non-woven felt plate.

[0067] Furthermore, the limiting mechanism comprises:

[0068] A first connecting portion 7, wherein the first connecting portion 7 is disposed on a side of the foam 1 away from an occupant;

[0069] At least one first limiting hole 9 is formed on the first connecting portion 7 ; the first air pipe 6 passes through the first limiting hole 9 and is connected to the air source assembly and the air bag assembly 10 respectively.

[0070] Specifically, refer to Figure 2 The first connecting portion 7 is fixedly mounted on the supporting plate 5 by means of a staple 18.

[0071] refer to Figure 11-16 The first limiting hole 9 can be in a rectangular hole shape, a waist-shaped hole shape, a round hole shape, a diamond-shaped hole shape, a triangular hole shape or a fan-shaped hole shape.

[0072] Furthermore, the first connecting portion 7 has a connecting portion 11;

[0073] The connecting portion 11 is clamped on the back spring 8 to fix the relative position of the first connecting portion 7 and the back spring 8 .

[0074] Specifically, the back spring 8 is fixedly connected to the seat frame. By clamping the connecting portion 11 on the back spring 8, the first connecting portion 7 can be installed at different positions. In actual operation, since there are many first air pipes 6, the first air pipes 6 are stacked, so the first connecting portion 7 is installed at the position corresponding to the back spring 8 to achieve the best effect of constraining the position of the first air pipe 6.

[0075] Furthermore, there are multiple first air pipes 6; multiple first limiting holes 9 are opened on the first connecting portion 7; and the multiple first air pipes 6 pass through the multiple first limiting holes 9 respectively.

[0076] Specifically, the manner in which the multiple first air pipes 6 respectively pass through different first limiting holes 9 can prevent the multiple first air pipes 6 from colliding with each other and generating noise.

[0077] Furthermore, the limiting mechanism also includes:

[0078] A support plate 5, the support plate 5 is arranged on the side of the foam 1 away from the occupant; the first connecting portion 7 is installed on the support plate 5;

[0079] The first connection portion 7 is fixedly mounted on the support plate 5 , or is integrally formed with the support plate 5 .

[0080] refer to Figure 1-3 In the first embodiment, the positions of the support plate 5, the first connecting portion 7, and the first air pipe 6 passing through the first limiting hole 9 are relatively fixed.

[0081] In one case, the air source component is an air circuit controller 19. When the air circuit controller 19 is working, the first air pipe 6 will shake with the inflation of the air bag 4 or the movement of the vehicle; however, the first connecting portion 7 constrains the position of the first air pipe 6 to prevent the first air pipe 6 from colliding with other components to generate noise.

[0082] In some embodiments, the support plate 5 further has a connecting buckle 22 for connecting with the back spring 8. Furthermore, the first connecting portion 7 can be integrally cut, sewn or pasted on the support plate 5; it can be a belt-shaped structure fixed on the support plate 5.

[0083] In some embodiments, the first connecting portion 7 includes:

[0084] The limiting ring 20 is fixedly mounted on the supporting plate 5 or is formed integrally with the supporting plate 5 , and the first air pipe 6 is arranged in the limiting ring 20 .

[0085] refer to Figure 4 In the second embodiment, the first connecting portion 7 is specifically a limiting ring 20.

[0086] Multiple first air pipes 6 are simultaneously arranged in the limiting ring 20. In this way, multiple first air pipes 6 can be limited at the same time to ensure that none of the multiple first air pipes 6 collides with the seat frame and generates noise.

[0087] In some embodiments, the first connection portion 7 and the support plate 5 are integrally formed; and a card seam 13 is opened on the support plate 5 .

[0088] The first connecting portion 7 comprises:

[0089] A restraining belt 14, one end of which is integrally formed with the supporting plate 5, and the other end of which has a clamping portion 15; the clamping portion 15 is used to be clamped in the clamping seam 13;

[0090] An annular structure is formed between the restraining belt 14 and the supporting plate 5 , and the first air pipe 6 passes through the annular structure to restrain the position of the first air pipe 6 .

[0091] refer to Figure 5-6 In the third embodiment, the first connection portion 7 is a restraint belt 14. The first air pipe 6 is restrained to limit the position. The restraint belt 14 is connected to the second connection plate 12 by a clamping portion 15 at the end thereof being clamped in the clamping seam 13. When there are multiple first air pipes 6, the multiple first air pipes 6 are restrained by one restraint belt 14 at the same time.

[0092] In some embodiments, the clamping portion 15 is made of a hard material with elastic deformation capability, or Velcro is used to increase the hardness of the clamping portion 15 to achieve clamping and fixing with the clamping seam 13 .

[0093] Furthermore, a mounting groove 16 is formed on the foam 1 ; the airbag assembly 10 is located in the mounting groove 16 .

[0094] Furthermore, the air bag assembly 10 and the limiting mechanism are respectively located on two sides of the foam 1;

[0095] The foam 1 is provided with a first through hole 2, and the first air pipe 6 passes through the first through hole 2;

[0096] The foam 1 is provided with a communication groove 17 ; the communication groove 17 is connected with the mounting groove 16 and the first through hole 2 ; the first air pipe is arranged in the communication groove 17 .

[0097] In some embodiments, the air bag 4 and the limiting mechanism are both located on the side of the foam 1 away from the passenger, and the first air pipe 6 does not need to pass through the first through hole 2 .

[0098] In some embodiments, the air bag 4 is disposed on the seat cushion, the first through hole 2 is located at a lower position, and the first air pipe 6 passes through the first through hole 2 and is connected to the air source assembly.

[0099] Specifically, refer to Figure 8-9 Since the air bag 4 is arranged on the side of the foam 1 close to the passenger, when massage is not needed, due to the thickness of the air bag 4 and the first air pipe 6, the foam 1 still bulges after the gas is exhausted, which may cause discomfort to the passenger.

[0100] Therefore, it is necessary to make the surface of the air bag 4 coplanar with the surface of the foam 1 after the air is exhausted when no massage is performed. In this embodiment, by providing the mounting groove 16 and the connecting groove 17 on the foam 1, the air bag 4 and the first air pipe 6 can be embedded in the foam 1 when not working, so as to avoid discomfort to the passengers.

[0101] Furthermore, the gas source assembly comprises:

[0102] An air source body, which is arranged on a side of the limiting mechanism away from the foaming device 1 and is used to inflate the airbag assembly 10 through the first air pipe 6;

[0103] At least one valve body assembly, which is installed on the gas source body or connected to the gas source body through a second air pipe; the other end of the valve body assembly is connected to the first air pipe 6 for controlling the gas source body to inflate the first air pipe 6.

[0104] Specifically, refer to Fig.10 , the air source body is an air pump or a vehicle body air source.

[0105] In some embodiments, the air bag 4 is directly connected to the air pump or the vehicle body air source through the first air pipe 6 without a valve body assembly installed therebetween.
