[0046] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0047] As described in the background, the inflated area of ​​conventional airbags is relatively small, making it difficult to effectively protect seat occupants in the event of a side collision. Therefore, the present application provides a new airbag component that effectively protects seat occupants in the event of a side collision, providing improved safety.

[0048] The structure of this application will be introduced and explained in detail below with reference to the accompanying drawings.

[0049] See also Figures 1 to 2 ,as well as Figure 7 and Figure 8 As shown, according to an embodiment of the present application, an airbag component 100 is provided. The airbag component 100 includes a main body 10 .

[0050] Specifically, the main body 10 in the present application is provided with a main cavity 11 and a secondary cavity 12 that are interconnected. The expansion volume of the main cavity 11 is suitable to be larger than the expansion volume of the secondary cavity 12, and the secondary cavity 12 is located on the outside of the main cavity 11; wherein, the main body 10 is suitable to be arranged on the side of the seat, the main cavity 11 is suitable to be arranged close to the occupant, and the secondary cavity 12 is suitable to be arranged on the side of the main cavity 11 away from the occupant.

[0051] It can be understood that the “main body 10 is suitable for being arranged on the side of the seat” described in this embodiment includes but is not limited to the main body 10 being directly installed on the side of the seat, or being supported by other structures and located on the side of the seat.

[0052] When the main body 10 is installed on a predetermined seat (for example, a vehicle seat 200, Figure 8 When the airbag component 100 is mounted on the vehicle seat 200 (as shown in FIG), the main cavity 11 is configured to be disposed close to the seat side of the seat (i.e., the main cavity 11 is closer to the occupant sitting on the vehicle seat 200 than the auxiliary cavity 12), and the auxiliary cavity 12 is configured to be disposed away from the seat side of the seat. Figure 8 ), after installation, the main chamber 11 is located near the seat side of the vehicle seat 200, that is, near the occupant sitting on the vehicle seat 200, and the secondary chamber 12 is located away from the seat side of the vehicle seat 200. In this way, when the vehicle is involved in a side collision, the airbag component 100 inflates to protect the occupant sitting on the vehicle seat 200.

[0053] Because the expansion volume of the main chamber 11 in this embodiment is larger than the expansion volume of the secondary chamber 12, when the main chamber 11 is inflated, it can protect the chest and abdomen of the occupant in the vehicle seat 200. Furthermore, since the main chamber 11 is positioned close to the occupant's body, when the airbag assembly 100 is inflated, the main chamber 11 is located below the occupant's protected arm. As the air in the main chamber 11 fills, it deploys upward from the occupant's side. This alleviates compression on the chest and abdomen to a certain extent, minimizing the overlap of the occupant's arm and chest laterally. This reduces impact damage to the chest and abdomen, effectively protecting the occupant in the vehicle seat 200.

[0054] At the same time, the secondary cavity 12 on the airbag component 100 in this embodiment is set away from the occupant, and the secondary cavity 12 is connected to the main cavity 11. The secondary cavity 12 can be inflated synchronously with the main cavity 11. When the secondary cavity 12 expands, the expansion of the secondary cavity 12 can cover a wider area of ​​the occupant, which is more suitable for effective protection of the occupant.

[0055] Furthermore, in some embodiments, the secondary cavity 12 at least partially protrudes from the top edge of the main cavity 11, and the portion protruding from the top edge of the main cavity 11 is higher than the abdomen and chest of the occupant, and can cover the shoulders of the occupant, thereby providing effective cushioning and protection for the shoulders of the occupant.

[0056] That is, in some usage scenarios, the airbag component 100 of the present application is installed on the side of the vehicle seat 200, that is, the vehicle seat 200 is close to the side of the vehicle. When the vehicle is involved in a side collision, the airbag component 100 is inflated. After the main chamber 11 located on the side close to the occupant is inflated, it can effectively cushion and protect the occupant's chest and abdomen. It can also allow the occupant's arms to stretch upward, avoiding excessive overlap of the arms with the chest and abdomen on the side of the human body, thereby squeezing the person's chest and abdomen. In addition, after the secondary chamber 12 located on the side away from the occupant is inflated, it can protrude from the top edge of the main chamber 11, thereby cushioning and protecting the occupant's shoulders. Compared to airbag components in the prior art, the airbag component 100 of the present application has a more comprehensive protection effect and protection range for the occupant after inflation, and can effectively protect the occupant sitting on the vehicle seat 200.

[0057] See also Figure 1 As shown, the secondary chamber 12 is located in the upper half of the exterior of the main chamber 11. The upper half here refers to the upper half of the airbag component 100 when in use. That is, in this embodiment, the secondary chamber 12 and the main chamber 11 can overlap and connect in the upper half of the main chamber 11, i.e., the secondary chamber 12 is located on the side of the main chamber 11 near the top. This arrangement makes it less likely that the secondary chamber 12 will expand when the airbag component 100 inflates, where it overlaps and is fixed to the main chamber 11, compared to other locations. This allows the gas in the main chamber 11 to fill toward the bottom of the main chamber 11, providing more effective cushioning and protection for the occupant's chest and abdomen. It also facilitates the occupant's arms being extended upward, preventing their arms from excessively overlapping with the chest and abdomen in the lateral direction of the human body, thereby squeezing the abdomen and chest.

[0058] Optionally, the main cavity 11 and the auxiliary cavity 12 in this embodiment can be circular, semicircular, polygonal or other special-shaped structures, which is not specifically limited in this application. As long as the deformation mode can effectively protect the occupants after inflation, it is within the protection scope of this application.

[0059] See also Figures 2 to 4As shown, in some embodiments, the main body 10 includes a first panel 111 and a second panel 112, which are integrally provided. The first panel 111 and the second panel 112 are folded and connected along a first fold 113 to enclose and form the main cavity 11. In other words, in this embodiment, the first panel 111 and the second panel 112 used to form the main cavity 11 are integrally provided, which has high structural strength, good stability, and lower production costs. During actual processing, the first panel 111 and the second panel 112 can be connected by at least one of sewing, suture connection, and adhesive connection. As long as other variations are based on the concept of this application, they are within the scope of protection of this application.

[0060] Of course, in other embodiments of the present application, the main cavity 11 can also be formed by sewing three or more pieces.

[0061] Furthermore, the main body 10 also includes a third panel 121 and a fourth panel 122. The third panel 121 and the fourth panel 122 are integrally arranged. The fourth panel 122 and the third panel 121 are folded and connected along the second fold 123 to enclose and form the secondary cavity 12. Because the third panel 121 and the fourth panel 122 in this embodiment are integrally arranged, when the airbag component 100 is actually manufactured, the entire secondary cavity 12 is cut from a single, integral panel, resulting in high structural strength, good stability, and lower production costs. Similarly, during actual processing, the fourth panel 122 and the third panel 121 can be connected by at least one of sewing, stitching, bonding, and other methods. Other variations of this invention, as long as they are within the scope of protection of this application, are also within the scope of protection of this application.

[0062] Of course, in other embodiments of the present application, the secondary cavity 12 can also be formed by sewing three or more pieces of cutting pieces.

[0063] Optionally, in some embodiments, the first panel 111 and the third panel 121 are integrally formed, that is, the entire airbag component 100 in this embodiment is formed by cutting and connecting a piece of material. After the first panel 111, the second panel 112, the third panel 121 and the fourth panel 122 are connected, the structural strength of the entire airbag component 100 is relatively high, and the number of parts that need to be sewn is relatively small, which can effectively reduce the production cost of the airbag component 100.

[0064] Furthermore, in order to make the secondary cavity 12 overlap and fix with the main cavity 11, in some embodiments, the third panel 121 is folded along the third fold 15 to be stacked with the first panel 111 and connected to the first panel 111. For example, the third panel 121 and the first panel 111 can be connected by at least one of sewing and bonding, see Figure 2As shown, the third panel 121 and the first panel 111 in this embodiment are sewn together along the sewing line 14. In this embodiment, the first panel 111 and the third panel 121 are sewn together, which can fix and constrain the main cavity 11 and the secondary cavity 12 to a certain extent, thereby stabilizing the shape and structural strength of the airbag component 100.

[0065] Furthermore, both the third panel 121 and the first panel 111 are provided with through holes 13. When the third panel 121 is folded along the third fold 15 to overlap with the first panel 111, the through holes 13 in the third panel 121 at least partially overlap and communicate with the through holes 13 in the first panel 111. Through the through holes 13 in the first and third panels 111, communication is achieved between the main chamber 11 and the secondary chamber 12 after the airbag component 100 is manufactured, facilitating rapid inflation and protection of the occupant during use.

[0066] For example, each of the first and second panels 111, 112 is provided with a plurality of through-holes 13. When the third panel 121 is folded along the third fold 15 to overlap with the first panel 111, the through-holes 13 on the third panel 121 correspond to and at least partially overlap with and communicate with the through-holes 13 on the first panel 111. In other words, after the airbag component 100 is sewn together, the primary and secondary chambers 11, 12, can communicate with each other through the plurality of through-holes 13, allowing for more uniform and rapid expansion.

[0067] Furthermore, the outer periphery of the through hole 13 in the third panel 121 is fixedly connected to the outer periphery of the through hole 13 in the first panel 111. In other words, after the through hole 13 in the first panel 111 and the through hole 13 in the third panel 121 are aligned, the outer peripheries are fixedly connected together. Specifically, the fixed connection can be made by at least one of sewing and bonding. This not only improves the structural strength of the entire airbag component 100, but also prevents airflow from entering the interlayer between the first panel 111 and the third panel 121 during inflation, thereby preventing leakage.

[0068] In some embodiments, the stitching line 14 between the first and third panels 111, 121 is arranged around the outer periphery of the first through-hole 13, further enhancing the structural strength and reliability of the airbag component 100 in this embodiment. During actual cutting, the third and fourth panels 121, 122 in this embodiment are arranged sequentially along a first direction, while the first and second panels 111, 112 are arranged sequentially along a second direction perpendicular to the first direction. This arrangement allows the secondary chamber 12 to overlap with one side of the main chamber 11, i.e., the top side of the main chamber 11 during use, after being folded and stitched together. This design is sophisticated and facilitates stitching.

[0069] Optionally, a reinforcing thread 114 is provided between the second panel 112 and the first panel 111. This reinforcing thread 114 is located in the upper half of the main chamber 11. That is, after the first and second panels 111, 112 are fixedly connected at their outer edges, a further reinforcing thread 114 is provided. This reinforcing thread 114 is used to connect the first and second panels 111, 112, thereby enhancing the structural strength of the entire airbag component 100. Furthermore, this reinforcing thread 114 is located in the upper half of the main chamber 11. When the main chamber 11 inflates, it can squeeze the gas within the main chamber 11 toward the lower half, providing better protection for the occupant and allowing the occupant's arms to extend upward. For example, the reinforcing thread 114 in this embodiment can be a suture, an adhesive, or other method. Any other method that can securely connect the first and second panels 111, 112 is within the scope of this application.

[0070] In some embodiments, when processing the airbag component 100 , the reinforcing connection line 114 overlaps with the suture line 14 , which can simplify the production process of the airbag component 100 and improve the production efficiency of the airbag component 100 .

[0071] Optionally, the reinforcing connecting line 114 and the suture line 14 in this embodiment can be at least one of a straight line and an arc, as long as they can securely connect the first panel 111 to the third panel 121 and the first panel 111 to the second panel 112. This is not a limitation in this application. In different embodiments, the use of the reinforcing connecting line 114 can be selected. The reinforcing connecting line 114 and a portion of the suture line 14 are positioned close to or overlap with each other, primarily to sew the two panels of the main chamber 11 and the panels of the secondary chamber 12, limiting the thickness at this location and allowing for better deflection of the airbag.

[0072] Combine Figures 1 to 5 As shown, in this embodiment, the second panel 112 is provided with a positioning portion 16, which is configured for at least the gas generator. For example, the positioning portion 16 in this embodiment is a positioning hole. In actual use, the positioning hole is connected to the gas generator (not shown). When the vehicle is involved in a side collision, the gas released by the gas generator is more likely to flow toward the second panel 112 of the main cavity 11, causing the main cavity 11 to deflect toward the occupant, more effectively extending the occupant's arms upward to reduce the pressure on the chest and abdomen, thereby effectively protecting the occupant.

[0073] In some embodiments, the airbag component 100 is installed on the seat by installing the airbag component 100 on the side of the seat through the positioning portion 16. That is, by setting the positioning portion 16 on the second panel 112, that is, the panel on the side close to the occupant, and making the positioning portion 16 offset from the first fold 113, when the airbag component 100 expands, the main cavity 11 can be deflected as a whole toward the side close to the occupant, that is, the deployment path of the main cavity 11 is close to the occupant's body and penetrates under the occupant's arm when deployed. As the main cavity 11 inflates, it fills the side space of the vehicle seat 200 and squeezes the arm. At the same time, the airbag component 100 also has a sub-cavity 12 to cover the occupant's shoulder, making up for the gap in the protection range caused by the main cavity 11 to the position under the arm, so that the side airbag component 100 can better protect the occupant in a collision accident. That is to say, the mounting portion of the gas generator in this embodiment is arranged on the second panel 112 rather than on the symmetrical folding line (i.e., the first fold 113) of the main cavity 11 panel in order to allow the main cavity 11 to deflect when unfolded, thereby being closer to the occupant's body. The position of the positioning portion 16 will be appropriately adjusted according to the specific environment.

[0074] Optionally, when the airbag component 100 is in a deflated state and flatly deployed (eg Figure 1 As shown), the distance between the positioning portion 16 and the first fold 113 is L1; on the main cavity 11, along the direction perpendicular to the first fold 113, the distance between the point A farthest from the first fold 113 and the first fold 113 is L2; ​​wherein, L2 / L1 satisfies the relationship: 1 / 5≤L1 / L2≤1 / 2, illustratively, L1 / L2 can be 1 / 2, 1 / 3, 1 / 4, 1 / 5, etc. Figure 1 、 Figure 8 As shown, when L1 / L2 is greater than 1 / 2, the distance between the positioning portion 16 and the first fold 113 is relatively large during inflation of the airbag component 100, and the width of the main chamber 11 protruding from the backrest surface of the vehicle seat 200 in the X direction is relatively small, making it difficult for the main chamber 11 to protect the occupant's abdomen and chest. When L1 / L2 is less than 1 / 5, the distance between the positioning portion 16 and the first fold 113 is too small, making it difficult for the main chamber 11 to deflect toward the occupant during inflation. In other words, by ensuring 1 / 5 ≤ L1 / L2 ≤ 1 / 2, this embodiment balances the protection range and deflection direction of the airbag component 100 during inflation, providing more effective occupant protection.

[0075] Furthermore, in some embodiments, at least one of the side walls of the main cavity 11 and the side walls of the auxiliary cavity 12 is provided with an exhaust hole 18. That is, in this embodiment, one or both of the side walls of the main cavity 11 and the auxiliary cavity 12 are provided with an exhaust hole 18. Through the function of the exhaust hole 18, the gas in the airbag component 100 is easily discharged. Figure 1As shown, this embodiment shows the situation where the exhaust hole 18 is set on the side wall of the sub-cavity 12. In actual design, the exhaust hole is located at the starting position of the suture line of the sub-cavity 12, which has a simple structure and is easy to process.

[0076] Combine Figures 2 to 4 As shown, when the airbag component 100 is actually sewn, the third panel 121 is first folded along the third fold 15 so that the third panel 121 and the first panel 111 are stacked. Then, the first panel 111 and the third panel 121 are sewn together along the sewing line 14, and at the same time, the third panel 121 is sewn together with the outer periphery of the through hole 13 on the first panel 111 (as shown in FIG. Figure 3 Then, the first panel 111 and the second panel 112 are sewn together along the first fold 113 and the second fold 123 (when sewing the first panel 111 and the second panel 112, the first panel 111 and the second panel 112 are assisted by sewing the first panel 111 and the second panel 112 along the reinforcing connecting line 114), and the third panel 121 and the fourth panel 122 are sewn together ( Figure 4 (The figure shows the situation where the third panel 121 and the fourth panel 122 are sewn together first). It is understood that during sewing, the second panel 112 and the fourth panel 122 are folded in opposite directions. After sewing, the main cavity 11 and the secondary cavity 12 are stacked. Of course, in other embodiments of the present application, the order of sewing and folding the panels can be adjusted, as long as the main cavity 11 and the secondary cavity 12 can be sewn together. This is not specifically limited in this application.

[0077] See also Figure 5 and Figure 6 As shown, in another embodiment of the present application, the main chamber 11 is provided with a pleated portion 17 on the side of the positioning portion 16 near the first fold 113. This pleated portion 17 is configured to increase the expansion space of the main chamber 11 when the main chamber 11 inflates. In actual manufacturing, a redundant panel portion can be provided between the positioning portion 16 and the first fold 113. When the first panel 111 and the second panel 112 are sewn and fixed, this redundant portion is sewn and pinched together to form the pleated portion 17. In this way, when the main chamber 11 inflates, the provision of the pleated portion 17 can increase the expansion space of the main chamber 11, further enhancing the protective range of the airbag component 100 for the occupant. Furthermore, because the pleated portion 17 is located on the side of the positioning portion 16 near the first fold 113, when the main chamber 11 inflates, it can deform relative to the secondary chamber 12, assisting the main chamber 11 in deflecting toward the occupant.

[0078] According to the above description, it can be known that the airbag component 100 of the present application is installed on the vehicle seat. During actual installation, the airbag component 100 is wrapped by foam and seat cover, and expands to protect the side shoulders, chest and abdomen of the occupant on the seat in a side collision accident of the vehicle. The airbag component 100 of the present application is provided with a main chamber 11 and a secondary chamber 12. When the airbag component 100 is deployed, the main chamber 11 mainly covers the chest and abdomen of the protected occupant, providing cushioning and protection. In addition, when the main chamber 11 is deployed, it will move closer to the occupant's body and deploy to the bottom of the occupant's protected arm. Due to the filling of gas in the main chamber 11, it deploys upward from the bottom of the side body, reducing the squeezing of the chest area. In the China New Car Assessment Program (CNCAP) side large barrier collision and China Insurance Automobile Safety Index (CIASI) small offset real vehicle collision tests, if the chest and arm do not overlap in the lateral space (i.e., lateral to the human body), the impact damage to the chest can be reduced, thereby achieving better protection for the front occupants.

[0079] In addition, the deflection feature of the airbag component 100 of the present application can more stably dislocate the arms and chest; since the deflected main cavity 11 will unfold under the arms of the protected occupant, the main cavity 11 will not cover the shoulders of the occupant after unfolding, while the secondary cavity 12 will cover the shoulders of the occupant after unfolding, providing cushioning and protection for the shoulders.

[0080] Second, see Figure 8 As shown, the present application also provides a vehicle seat 200, which includes an airbag assembly 100. During installation, the airbag assembly 100 is mounted on a side of the vehicle seat 200, specifically on the side of the vehicle seat 200 near the vehicle door. The airbag assembly 100 in this embodiment is the same as the airbag assembly 100 described above. Therefore, the vehicle seat 200 includes all the technical effects of the airbag assembly 100 in the above-described embodiment. Since the technical effects of the airbag assembly 100 have been described in detail above, they will not be repeated here.

[0081] Thirdly, see Figure 9As shown, the present application also provides a vehicle 300, which includes the aforementioned vehicle seat 200. The airbag assembly 100 of the vehicle seat 200 is located on the side of the vehicle seat 200 near the door of the vehicle 300. When the vehicle 300 is involved in a side collision, the airbag assembly 100 can inflate, thereby protecting the occupant sitting in the vehicle seat 200. Since the vehicle 300 in this embodiment includes the aforementioned vehicle seat 200, the vehicle 300 includes all the technical effects of the vehicle seat 200 described above. Since the technical effects of the vehicle seat 200 have been described in detail above, they will not be repeated here.
