[0033] To facilitate understanding of the present invention, the following description is provided in conjunction with the accompanying drawings and embodiments.

[0034] Please see attached Figure 2-4 , 6, 7 and 9, a car seat for preventing foam from moving, comprising a backrest frame 3 and foam and a surface cover covering the backrest frame 3, a cavity for accommodating an airbag housing 4 is formed between the front part 1 and the rear part 2 of at least one side of the foam.

[0035] The car seat can be a conventional car seat in the prior art, in which the foamed rear part 2 moves laterally when the car seat cover is wrapped, especially a car seat in which the foamed rear part 2 moves laterally due to the lack of support and fixation caused by the embedded airbag housing 4. The structure of the car seat and the embedded airbag housing 4 are both prior art and will not be described in detail here.

[0036] The automobile seat further comprises a connection mechanism, which is connected between the foamed rear portion 2 and a fixed component in the automobile seat to limit the movement of the foamed rear portion 2 relative to the backrest frame 3 .

[0037] Preferably, the connection portion between the connection mechanism and the foamed rear portion 2 may be located on the back side of the foamed rear portion 2 (the side facing the inside of the car seat is the back side, and the side facing the outside of the car seat is the front side).

[0038] By setting the connecting mechanism, a tie is formed between the foamed rear part 2 and the fixed parts in the car seat, providing support and fixation for the foamed rear part 2, so that the foamed rear part 2 is fixed in the car seat, solving the problem of lateral movement of the foamed rear part 2.

[0039] The fixed components in the automobile seat include one or a combination of a foamed front portion 1, a backrest frame 3 of a seat frame and an airbag housing 4.

[0040] One end of the connecting mechanism is fixed to the foamed rear part 2. When selecting the fixing position of the other end of the connecting mechanism, a fixing component close to the foamed rear part 2 can be selected, such as the foamed front part 1, the backrest frame 3 of the seat frame and the airbag shell 4. Other fixing components can also be selected according to the actual car seat structure. The fixing component can be of one type, or a combination of multiple fixing components can be selected according to the fixing requirements, so as to provide a pulling force in the opposite direction of the stringing direction to the foamed rear part 2, thereby avoiding lateral stringing of the foamed rear part 2 after being subjected to force.

[0041] Please see attached Figure 2 , Example 1:

[0042] The fixing component is the foamed front part 1, and the connecting mechanism is a flexible connector 5. One end of the flexible connector 5 is fixed to the foamed front part 1, and the other end of the flexible connector 5 is fixed to the foamed rear part 2. The flexible connector 5 can be arranged between the foamed front part 1 and the foamed rear part 2 along the fitting surface of the backrest frame 3 and the airbag shell 4, so that the foamed rear part 2 and the foamed front part 1 are relatively fixed.

[0043] By setting the flexible connecting member 5, the foamed rear part 2 is relatively fixed to the foamed front part 1, providing the foamed rear part 2 with a pulling force in the opposite direction of the stringing direction, thereby avoiding the lateral stringing of the foamed rear part 2.

[0044] Preferably, the flexible connecting member 5 is made of non-woven fabric.

[0045] When selecting the flexible connector 5, due to the limitation of the installation space, the rear of the flexible connector 5 cannot exceed 3 cm, and its strength requirement is greater than (220±60)N / 5cm in the longitudinal direction and greater than (450±100)N / 5cm in the transverse direction. The flexible connector 5 can be selected as non-woven fabric, which is thin and soft, and can fit the contour of the backrest frame 3 and the shell of the airbag shell 4, without taking up space, and does not affect the embedding of the airbag shell 4 and the use of the airbag inside.

[0046] When the foamed front part 1 and the foamed rear part 2 are manufactured, the two ends of the non-woven fabric can be respectively injection molded on the foamed front part 1 and the foamed rear part 2, and the one-time molding manufacture has a simple structure and is easy to install. The two ends of the non-woven fabric can also be fixed to the foamed front part 1 and the foamed rear part 2 by gluing, sewing, etc. during the assembly process.

[0049] The suspension wire 301 is an original fixed component on the backrest frame 3, which can provide a stable hanging point for the other end of the flexible connector 5. The structure of the backrest frame 3 itself is used to provide traction in the opposite direction of the stringing direction for the foamed rear part 2, thereby avoiding lateral stringing of the foamed rear part 2. No additional parts are needed, the structure is simple, easy to arrange and implement, and the cost is low.

[0050] One end of the flexible connector 5 is fixed to the foamed rear portion 2 by means of a staple 7 or embedding, and the other end of the flexible connector 5 passes through the side plate of the backrest frame 3 and is hung on the suspension wire 301 of the backrest frame 3 .

[0051] A first hole is formed on the side panel of the backrest frame 3 for the flexible connector 5 to pass through, and a second hole is formed on the other end of the flexible connector 5 for hanging the suspension wire 301, so that the flexible connector 5 can be connected between the foamed rear part 2 and the suspension wire 301, thereby fixing the foamed rear part 2 and the backrest frame 3 relatively.

[0052] Preferably, the flexible connector 5 may be made of felt cloth, and the felt cloth may be made of flexible materials such as PP felt, PP+PET felt, etc.

[0053] The flexible connector 5 is embedded in the foamed rear part 2 in the following way: during foaming, one end of the flexible connector 5 can be fixed to the foamed rear part 2 through an insert injection molding process, thereby making it easier to connect the subsequent flexible connector 5 between the foamed rear part 2 and the suspension steel wire 301.

[0054] Please see attached Figure 4 and attached Figure 5 , Example 3:

[0055] The fixed component is a backrest frame 3 , and the connecting mechanism includes a flexible connecting member 5 ; one end of the flexible connecting member 5 is fixed to the foamed rear portion 2 , and the other end of the flexible connecting member 5 is clamped on the side panel of the backrest frame 3 .

[0056] One end of the flexible connector 5 is fixed to the foamed rear portion 2 by means of a staple 7 or embedding, and the other end of the flexible connector 5 is engaged with the card interface 302 on the side panel of the backrest frame 3 through the card slot 801 .

[0057] By utilizing the original card interface 302 on the side panel of the backrest frame 3, a U-shaped card slot 801 matching the card interface 302 is set at the other end of the flexible connector 5, thereby facilitating the connection between the other end of the flexible connector 5 and the side panel of the backrest frame 3, which is convenient and quick to install, has a simple structure, and occupies little space.

[0058] Preferably, the flexible connector 5 may be made of felt cloth, and the felt cloth may be made of flexible materials such as PP felt, PP+PET felt, etc.

[0059] The flexible connector 5 is embedded in the foamed rear part 2 in the following way: during foaming molding, one end of the flexible connector 5 can be fixed to the foamed rear part 2 through an insert injection molding process, thereby making it easier to connect the subsequent flexible connector 5 between the foamed rear part 2 and the side panel of the backrest frame 3.
