[0001] This application relates to the field of vehicle component technology, and in particular to an airbag guiding assembly, an airbag assembly, an automobile seat, and a vehicle. Background Technology

[0002] As a crucial component of automotive passive safety systems, airbag modules play a vital role in driving safety. To ensure that the airbag module can inflate and deploy quickly and accurately in the event of a collision, providing effective protection for passengers, an airbag guide fabric is used to wrap and secure the airbag module.

[0003] In related technologies, airbag guide fabric is typically connected to the seat cover. Specifically, one end of the airbag guide fabric is sewn to the seam of the weakened groove in the seat cover, and the other end is sewn with a buckle. When the seat cover is used to cover the seat frame, the airbag guide fabric wraps around the airbag module and is then fastened at the rear end of the seat frame. When the airbag module deploys, the airbag guide fabric guides the airbag, allowing it to unfold from the foam and the weakened groove in the seat cover. However, when a set of seat covers is required, the installation of the airbag guide fabric becomes very difficult, especially for vehicles with remote airbag designs, where assembly is more challenging and production efficiency is affected.

[0017] Optionally, the airbag guide fabric includes a first wrap and a second wrap disposed opposite to each other;

[0018] The first and second fabric layers are connected at their opposite edges along the length of the airbag module to form the airbag guide fabric.

[0019] Optionally, the shape of the edge of the first covering fabric away from the second covering fabric is flush with the edge of the cushioning structure;

[0020] The shape of the edge of the second covering fabric away from the first covering fabric is flush with the edge of the cushioning structure.

[0040] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0041] In related technologies, the airbag guide fabric is usually connected to the face cover. One method involves sewing both ends of the airbag guide fabric to the seat cover. After being covered by the face cover, the airbag guide fabric directly covers the surface of the foam material, which can strengthen the foam in the corresponding area of ​​the airbag module and promote the airbag to deploy from the weakened grooves of the foam and face cover when the airbag module explodes. The main drawback of this method is that when the airbag of the airbag module is large and the amount of propellant in the airbag module increases, the airbag module may not deploy from the weakened grooves of the foam and face cover, resulting in damage to the foam and face cover and excessive splatter.

[0042] Firstly, please refer to Figure 1 This application provides an airbag guiding assembly, including an airbag guiding fabric 1, a buffer structure 2, and a face cover 3. The airbag guiding fabric 1 is used to cover the airbag module 4, the buffer structure 2 is disposed on at least a portion of the periphery of the airbag guiding fabric 1, and the buffer structure 2 has a weakening groove 21. The face cover 3 covers the periphery of the buffer structure 2, and the airbag guiding fabric 1 and the face cover 3 are independent of each other.

[0043] The airbag guide fabric 1 covers the airbag module 4 and provides guidance during the explosion of the airbag module 4. The buffer structure 2 provides protection for the airbag module 4 and has a weakening groove 21. When the airbag module 4 explodes, it will burst and unfold from the weakening groove 21 of the buffer structure 2 with the cooperation of the airbag guide fabric 1. The face cover 3 covers the outer periphery of the airbag guide fabric 1 and the buffer structure 2, fixing the airbag guide fabric 1 and the buffer structure 2. By making the airbag guide fabric 1 and the face cover 3 independent of each other, the airbag guide fabric 1 can be installed separately during the assembly process, and then the face cover 3 can be installed, which reduces the installation difficulty and improves the assembly efficiency. That is, the airbag guiding component provided in this application embodiment can effectively cover the airbag module 4, improve the accuracy of guiding the airbag module 4 during explosion, and thus reduce the risk of excessive debris during the explosion of the airbag module 4. Moreover, since the airbag guide fabric 1 and the face cover 3 are independent of each other and are not connected, the overall assembly difficulty can be reduced and the assembly efficiency can be improved.

[0044] The airbag guide fabric 1 directly covers the outer perimeter of the airbag module 4, providing excellent protection and ensuring proper guidance during the airbag module 4's explosion. This reduces the impact of the airbag module 4's excessive size after explosion and minimizes the generation of debris. Furthermore, the airbag guide fabric 1 and the face cover 3 are independent of each other; there is no connection between them. During assembly, the airbag guide fabric 1 can be wrapped around the airbag module 4 first, followed by the installation of the assembled airbag guide fabric 1 and airbag module 4, and then the face cover 3 can be placed around the outer perimeter of the buffer structure 2. Since it is not necessary to assemble the airbag module 4 after applying the face cover 3, the operation difficulty is reduced and the assembly efficiency is improved.

[0045] Among them, the buffer structure 2 can be a foam structure. The foam structure has the advantage of being lightweight and can absorb a certain amount of energy when it is impacted, thereby improving safety. In addition, the foam structure can be tightly integrated with other components to form a whole.

[0046] In some embodiments, please refer to Figure 1 At least part of the airbag guide fabric 1 is embedded in the weakening groove 21.

[0047] By embedding at least a portion of the airbag guide fabric 1 within the weakening groove 21, the airbag guide fabric 1 can expand when the airbag module 4 bursts. The portion of the airbag guide fabric 1 embedded within the weakening groove 21 opens the foaming component from the weakening groove 21, thereby allowing the airbag module 4 to fully deploy and ensuring the guiding and deployment effects of the airbag module 4.

[0048] In some embodiments, please refer to Figure 1The airbag guide fabric 1 includes a covering part 11 and a guide part 12. The covering part 11 has a first cavity covering the airbag module 4, and the guide part 12 is at least partially located in the weakening groove 21. The guide part 12 is used to form a guide channel communicating with the first cavity in the weakening groove 21.

[0049] The airbag module 4 is located within the first cavity of the covering portion 11, and the guide portion 12 forms a guide channel communicating with the first cavity within the weakening groove 21. When the airbag module 4 bursts, the first cavity of the covering portion 11 expands, thereby causing the guide channel communicating with the first cavity to expand as well. Since the guide portion 12 is at least partially located within the weakening groove 21, the expansion of the guide channel can compress the buffer structure 2 at the weakening groove 21, facilitating the deployment of the airbag module 4 from the weakening groove 21. The side of the guide portion 12 away from the covering portion 11 can be non-enclosed, facilitating the directional release of pressure during the bursting of the airbag module 4 and improving the accuracy of guidance.

[0050] In some embodiments, please refer to Figure 1 The buffer structure 2 includes a first buffer element 22 and a second buffer element 23. The first buffer element 22 and the second buffer element 23 are spaced apart to form a weakening groove 21.

[0051] In other words, the buffer structure 2 includes a first buffer 22 and a second buffer 23 arranged opposite to each other, with a gap between the first buffer 22 and the second buffer 23, forming a weakening groove 21. When the airbag module 4 bursts, the impact force generated by the burst causes the first buffer 22 and the second buffer 23 to expand from the weakening groove 21 and move away from each other, thereby causing the burst airbag to deploy.

[0052] In some embodiments, please refer to Figures 2-4 An obstacle avoidance structure 13 is provided on the airbag guide fabric 1. The obstacle avoidance structure 13 is used to avoid the fixing part 41 on the airbag module 4.

[0053] The fixing part 41 provided on the airbag module 4 is used to fix the airbag module 4 to the seat frame 20 or other positions, improving installation stability. The avoidance structure 13 provided on the airbag guide cloth 1 can avoid the fixing part 41 on the airbag module 4, making it easier for the fixing part 41 to dock with the seat frame 20 or other positions, reducing the difficulty of installation.

[0054] In some embodiments, please refer to Figures 2-4 The length of the airbag module 4 is L1, and the length of the airbag guide cloth 1 in the length direction X of the airbag module 4 is L2, wherein 20mm≤L2-L1≤60mm.

[0055] In other words, in the length direction X of the airbag module 4, the length of the airbag guide cloth 1 is greater than the length of the airbag module 4, and the length of the airbag guide cloth 1 exceeds the length of the airbag module 4 by 20mm-60mm. This allows the airbag guide cloth 1 to effectively cover the airbag module 4 and facilitates the smooth deployment of the airbag module 4 during explosion, ensuring the guiding effect of the airbag guide cloth 1 on the direction of the airbag module 4's explosion deployment.

[0056] For example, the length of the airbag module 4 can be 240mm, and the length of the airbag guide cloth 1 along the length direction X of the airbag module 4 can be 280mm.

[0057] In some embodiments, please refer to Figure 5 The airbag guide fabric 1 includes a first cover fabric 14 and a second cover fabric 15 disposed opposite to each other. The edges of the first cover fabric 14 and the second cover fabric 15 are connected to each other at opposite ends in the length direction X of the airbag module 4 to form the airbag guide fabric 1.

[0058] By connecting the edges of the first and second covering fabrics 14 and 15 at opposite ends along the length X of the airbag module 4, a space can be formed between the first and second covering fabrics 14 and 15 to accommodate the airbag module 4, thus enclosing the airbag module 4 inside the airbag guide fabric 1. Using the first and second covering fabrics 14 reduces the processing difficulty of the airbag guide fabric 1 and improves its adaptability and flexibility to different airbag modules 4, facilitating the installation and removal of the airbag module 4.

[0059] For example, the first covering fabric 14 and the second covering fabric 15 can be integrally formed, with one side of the first covering fabric 14 and one side of the second covering fabric 15 being integrally formed. The edges of the first covering fabric 14 and the second covering fabric 15 at opposite ends along the length X of the airbag module 4 are connected to each other by stitching. The integral forming and stitching method can improve the overall structural stability of the airbag guide fabric 1, reduce the difficulty of covering the airbag module 4, and improve the adaptability to airbag modules 4 of different shapes.

[0060] Specifically, for the airbag guide fabric 1 composed of the first cover fabric 14 and the second cover fabric 15, when sewing, the first cover fabric 14 and the second cover fabric 15 can be folded in half first, and then 90# sewing thread can be used to sew at the opposite ends in the length direction X of the airbag module 4 at a distance of 7mm and 15mm from the edge. At the beginning and end of the sewing, 3-5 stitches are added to improve the stability of the sewing.

[0061] In some embodiments, please refer to Figure 1 , Figure 4 and Figure 5The shape of the edge of the first covering fabric 14 away from the second covering fabric 15 is flush with the edge of the cushioning structure 2. The shape of the edge of the second covering fabric 15 away from the first covering fabric 14 is flush with the edge of the cushioning structure 2.

[0062] By setting the edge of the first fabric 14 away from the second fabric 15 and the edge of the second fabric 15 away from the first fabric 14 flush with the edge of the buffer structure 2, on the one hand, the shape matching degree between the airbag guide fabric 1 and the buffer structure 2 can be improved, ensuring the overall structural stability and aesthetics. On the other hand, by setting them flush, the guiding effect can be improved, so that when the airbag module 4 bursts, it can expand from the weakening groove 21 of the buffer structure 2, thereby allowing the airbag module 4 to fully deploy.

[0063] In some embodiments, the face cover 3 is a set-type face cover. The set-type face cover is fitted around the airbag guide fabric 1 and the cushioning structure 2.

[0064] The sleeve-type cover refers to a cover with only one opening, installed in a manner similar to an envelope, and fitted over the airbag guide fabric 1 and the buffer structure 2 through the opening, providing good integrity and aesthetics. Since the airbag guide fabric 1 and the cover 3 are not connected in this embodiment, they can be installed independently with minimal interference or influence between them. This reduces installation difficulty, improves installation efficiency, and enhances the overall stability and aesthetics of the airbag guide assembly.

[0065] Secondly, embodiments of this application also provide an airbag assembly, including an airbag module 4 and an airbag guide assembly as described above, wherein the airbag guide assembly provides burst guidance for the airbag module 4.

[0066] The airbag assembly provided in this application has all the beneficial effects of the airbag guide assembly described above, and will not be repeated here.

[0067] Thirdly, embodiments of this application also provide an automobile seat, including the airbag assembly described above.

[0068] The car seat provided in this application embodiment has all the beneficial effects of the airbag guiding assembly described above, which will not be repeated here.

[0069] In some embodiments, please refer to Figures 6-7 The car seat also includes a seat frame 20. The airbag assembly is mounted on the seat frame 20.

[0070] By mounting the airbag assembly onto the seat frame 20, structural stability can be improved. Specifically, the airbag module 4 is fixed to the seat frame 20 by the fixing part 41, then the first buffer 22 and the second buffer 23 are mounted on the seat frame 20, and then the cover 3 is placed around the buffer structure 2. The cover 3 provides a covering effect for the airbag guide assembly and the buffer structure 2, ensuring the overall structural stability, and also improves the aesthetics of the car seat.

[0071] According to a fourth aspect of this application, a vehicle is also provided, including the airbag assembly as described above, and / or, the vehicle seat as described above.

[0072] The vehicle provided in this application embodiment has all the beneficial effects of the airbag assembly described above, which will not be repeated here.
