[0026] like Figure 1-6As shown, a side airbag assembly of this utility model includes a gas generator 1, an air bag 2, a buckle 3, and a cable tie 4.

[0027] The gas generator 1 is located inside the air bag 2, with a wiring harness connection end 11 at one end. The wiring harness connection end 11 penetrates the side wall of the air bag 2 and extends to the outside of the air bag 2 for connecting to the vehicle wiring harness. The buckle 3 has a hook end 31 at one end and an mounting end 32 at the other. The hook end 31 is located outside the air bag 2 for quick engagement with the seat back 5. The mounting end 32 penetrates the side wall of the air bag 2 and extends into the interior of the air bag 2, and is securely connected to the gas generator 1 by a cable tie 4.

[0028] This structure eliminates the traditional step of welding studs onto the gas generator 1, simplifying the manufacturing process of the airbag assembly and reducing production difficulty. Furthermore, since the hook end 31 is directly exposed to the outside of the airbag 2, no nuts or tools are needed during final assembly at the seat factory; assembly can be completed simply by insertion, significantly improving assembly convenience and facilitating future maintenance and replacement.

[0029] In this embodiment, sealing structures are provided at the penetration points between the wiring harness connection end 11 and the air bag 2, and between the mounting end 32 and the air bag 2. These sealing structures can be of various types well-known to those skilled in the art. For example, the fabric material of the air bag 2 can be fused with the corresponding component using a hot-melt process to form an integral seal. Alternatively, sealant can be applied to the penetration points to achieve an adhesive seal. Or, a rubber sealing ring can be added during assembly, utilizing the clamping force of the components to achieve a compression seal. Alternatively, high-density stitching with sealing thread can be used at the perforation edge of the air bag 2 to prevent gas leakage through the dense stitches. These sealing measures effectively prevent gas leakage from the air bag 2 during inflation and deployment due to the perforation, thereby ensuring the functional reliability and safety performance of the side airbag assembly.

[0030] The buckle 3 is made of metal or plastic. A snap-fit ​​elastic surface 33 is provided between its hook end 31 and mounting end 32, located outside the air bag 2. When the hook end 31 is fully inserted into the mounting hole 501 on the seat back 5, the snap-fit ​​elastic surface 33 abuts against the sheet metal surface surrounding the mounting hole 501, generating an elastic reaction force and providing a stable locking force. This effectively prevents the buckle 3 from loosening or shaking during vibration or use, improving the reliability of the long-term connection.

[0031] Furthermore, the hook end 31 adopts a double hook structure, which includes two hook-shaped locking parts arranged side by side or symmetrically. This double hook structure can form a dual locking mechanism when the vehicle is involved in a side collision, effectively dispersing the impact load, improving the overall structural strength and resistance to high dynamic impacts of the locking part, and preventing the airbag assembly from falling off due to single-point failure, thereby enhancing the protection reliability of the passive safety system.

[0032] To improve installation stability, at least two clips 3 are provided on the side of the airbag 2, spaced apart along the length of the airbag 2. This multi-point engagement not only achieves a more balanced force distribution but also effectively suppresses deflection or swaying during airbag deployment, ensuring that the airbag 2 deploys along a predetermined trajectory and improving occupant protection consistency.

[0033] In the specific assembly, the cable tie 4 and the buckle 3 can adopt a separate structure: the mounting end 32 located inside the air bag 2 has a through hole 3201, and the cable tie 4 passes through the through hole 3201 and surrounds the gas generator 1 and is pulled tight.

[0034] Alternatively, the cable tie 4 and the buckle 3 can be integrally formed into a buckle-integrated cable tie structure, such as the detachable integrated cable tie with washer disclosed in the utility model with authorization announcement number CN217049808U.

[0035] Based on the above structure, this utility model also provides an installation structure for a side airbag assembly, including the aforementioned side airbag assembly and a seat back 5. The side airbag assembly is snapped onto the seat back 5 via a clip 3, requiring no additional fasteners.

[0036] Specifically, the seat backrest 5 has mounting holes 501 for the hook end 31 to engage. The mounting holes 501 are either oblong or have a groove structure with barbs. During assembly, the hook end 31 is aligned with the mounting hole 501 and pushed in until a "click" sound is heard, indicating that it is engaged, achieving efficient and reliable tool-free quick installation.

[0037] Furthermore, this utility model also provides a vehicle that includes the aforementioned side airbag assembly mounting structure. This vehicle, while ensuring high safety performance, significantly improves the assembly efficiency and maintenance convenience of the side airbag module, reduces overall vehicle manufacturing costs and cycle time, and meets the comprehensive needs of modern automobiles for efficient manufacturing and highly reliable safety systems.

[0038] The method of using a side airbag assembly according to this utility model is as follows: Pre-set mounting holes 501 on the seat back 5, move the side airbag assembly with the pre-installed buckle 3 to the corresponding position on the seat back 5, align the hook end 31 with the mounting hole 501 and push it in until a clear "click" sound is heard, indicating that the buckle 3 has been reliably locked, and the installation of the side airbag assembly is completed.

[0039] The above are merely preferred embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
