[0050] In summary, the present invention adopts a new air curtain wrapping piece 14 to constrain the folded size of the air curtain. Under the premise of ensuring product performance, it has the advantages of small size and light weight. This not only helps to make the car lighter, improve the performance and energy efficiency of the car, but also optimize the spatial layout of the vehicle to a certain extent. At the same time, by integrating the components together, the process steps are simplified, which is conducive to shortening the manufacturing cycle. In the automobile production process, the shortened production cycle means higher production efficiency and lower production costs, which can enhance the market competitiveness of automobile manufacturers.

[0051] like Fig.10 As shown, an embodiment of the present invention provides a novel method for installing a head air curtain wrapping structure, comprising the following steps:

[0052] Step 1: Align the wrapping piece positioning hole 20 on the air curtain wrapping piece 14, the ear piece positioning hole 21 on the air curtain ear piece 13, and the main body positioning hole 22 on the air curtain connecting piece 12 to ensure that the positions of the components are accurate;

[0053] Step 2: The aligned air curtain wrapping piece 14, the air curtain ear piece 13 and the air curtain connecting piece 12 are sutured and fixedly connected by sutures 26 to form a preliminary integral structure;

[0054] Step 3: Wrap the air curtain wrapping sheet 14 around the folded air curtain body 11, and pass the other end of the air curtain wrapping sheet 14 through the ear plate through hole 15 on the air curtain ear plate 13, so that the wrapping sheet fixing hole 16 on the air curtain wrapping sheet 14 and the ear plate fixing hole 17 on the air curtain ear plate 13 are overlapped and aligned;

[0055] Step 4: Pass the screw 181 through the wrapping sheet fixing hole 16 and the ear sheet fixing hole 17 at the same time, and sleeve the reinforcing gasket 184 on the outer wall of the screw 181;

[0056] Step 5: Fix the entire head air curtain wrapping structure to the installation position on the car through the screw 181.

[0057] In summary, the present invention provides a wrapping piece positioning hole 20 on the air curtain wrapping piece 14, an ear piece positioning hole 21 on the air curtain ear piece 13, and a main body positioning hole 22 on the air curtain connecting piece 12, so that the components can be accurately aligned during installation to ensure accurate positioning, which not only improves the installation efficiency and reduces the installation error, but also makes the entire installation process more convenient, reduces the technical requirements for the installer, and also ensures the consistency and accuracy of each installation; the air curtain connecting piece 12, the air curtain ear piece 13 and one end of the air curtain wrapping piece 14 are fixedly connected by sutures 26 to form a stable connection structure. This suture connection method is simple and reliable, low in cost, and can withstand a certain amount of tension and stress, ensuring that the components will not be easily separated under daily use and slight vibrations; the wrapping piece fixing hole 16 of the air curtain wrapping piece 14 and the ear piece fixing hole 17 of the air curtain ear piece 13 are connected by an air curtain fixing component 18, and the screw 181 in the air curtain fixing component 18 passes through the fixing hole, and cooperates with structures such as a reinforcement sheet 183 and a reinforcement gasket 184 to further enhance the firmness of the connection. The cooperation between the reinforcement sheet 183 and the second reinforcement ring 24, and the reinforcement gasket 184 and the first reinforcement ring 23, enables the connection parts to withstand greater forces, preventing loosening or falling off when the air curtain main body 11 is inflated or impacted by external force, thereby ensuring the stability of the entire air curtain wrapping structure during operation; by setting a wrapping sheet weakening line 19 on the air curtain wrapping sheet 14, the air curtain wrapping sheet 14 is convenient for the air curtain main body 11 to be rapidly inflated. The air curtain wrapping sheet 14 is disconnected from the wrapping sheet weakening line 19 under the action of pressure, thereby quickly releasing the wrapping of the air curtain main body 11, allowing the air curtain main body 11 to be rapidly inflated and deployed in a very short time, providing timely and effective buffering protection for the passenger's head. This design can ensure that the air curtain responds quickly at critical moments, maximizes the role of protecting the head, and reduces the damage to passengers in collision accidents.

[0058] When the present invention is working: a new type of head air curtain wrapping structure proposed by the present invention is installed at a waiting installation position on the automobile according to a new type of installation method of the head air curtain wrapping structure. When the automobile collides with an emergency situation, the air curtain main body 11 is rapidly inflated and expanded. At this time, the wrapping piece weakening line 19 on the air curtain wrapping piece 14 comes into play. Since the internal gas pressure of the air curtain main body 11 increases rapidly, the air curtain main body 11 exerts a strong force on the air curtain wrapping piece 14. Through the setting of the wrapping piece weakening line 19, the air curtain wrapping piece 14 is disconnected from the wrapping piece weakening line 19 under this force, thereby releasing the wrapping of the air curtain main body 11. The air curtain main body 11 can be rapidly inflated and expanded to provide an effective buffering protection space for the passenger's head. During the whole process, the air curtain connecting piece 12 is fixedly connected with the air curtain ear piece 13 and the air curtain wrapping piece 14 to ensure the integrity of the air curtain main body 11 and other components. The wrapping piece fixing hole 16 on the air curtain wrapping piece 14 and the ear piece fixing hole 17 on the air curtain ear piece 13 are connected by The air curtain fixing component 18 is tightly connected, and the screw 181 in the air curtain fixing component 18 passes through two fixing holes, the reinforcement sheet 183 cooperates with the second reinforcement ring 24, and the reinforcement gasket 184 cooperates with the first reinforcement ring 23, which enhances the stability and sealing of the connection, and prevents the air curtain wrapping sheet 14 and the air curtain ear sheet 13 from detaching or loosening during the inflation process of the air curtain main body 11. At the same time, the hexagonal head 182 on the screw 181 facilitates the installation and disassembly operations, and the chamfered portion 185 facilitates the screw 181 to be inserted into the fixing hole of the car installation position for fixing, ensuring that the entire head air curtain wrapping structure is firmly installed on the car. During the installation process, the alignment and positioning of the wrapping sheet positioning hole 20, the ear sheet positioning hole 21 and the main body positioning hole 22 ensure the accuracy of the installation position of each component, providing a basic guarantee for the correct operation of the air curtain in an emergency. In this way, the head air curtain wrapping structure of the present invention can stably play a role in protecting the head when the car collides, and provide effective safety protection for passengers.

[0059] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of various changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
