[0030] Figures 1 to 3 illustrate the structure of an airbag assembly in one embodiment of the present disclosure, wherein Figure 1 illustrates the assembled structure of the airbag assembly, Figure 2 illustrates the exploded structure of the airbag assembly, and Figure 3 illustrates the structure of the airbag bag. Figures 4 to 6 illustrate the structure of an airbag assembly in another embodiment of the present disclosure, wherein Figure 4 illustrates the assembled structure of the airbag assembly, Figure 5 illustrates the exploded structure of the airbag bag assembly, and Figure 6 illustrates the structure of the airbag bag. In conjunction with Figures 1 to 6, the airbag bag assembly provided in the embodiment of the present disclosure includes:

[0031] Folded airbag bag 10;

[0032] The restraining roll 20 is mounted on the airbag bag 10;

[0033] Among them, the airbag bag 10 is provided with a locking structure 11 and the restraining roll 20 is provided with a notch structure 22, or the restraining roll 20 is provided with a locking structure and the airbag bag 10 is provided with a notch structure, and the locking structure 11 can be locked into the notch structure 22, so that the restraining roll 20 and the airbag bag 10 limit each other.

[0034] 1 to 6 , the locking structure 11 is shown to be disposed on the airbag bag 10 and the notch structure 22 is disposed on the restraining roll 20 , but the present invention is not limited thereto. In other embodiments, the locking structure may be disposed on the restraining roll 20 and the notch structure may be disposed on the airbag bag 10 .

[0035] The present invention cooperates with the binding roll 20 and the airbag bag 10, and utilizes the design of providing a locking structure 11 on one side and a notch structure 22 on the other side, and the locking structure 11 is locked into the notch structure 22, so as to conveniently and effectively bundle the airbag bag 10. It is convenient to operate, saves assembly time, and improves installation efficiency. It can also prevent the airbag bag 10 and the binding roll 20 from rotating, shifting or other relative movements that may cause the airbag bag 10 / binding roll 20 to loosen, thereby achieving stable bundling of the airbag bag 10.

[0036] The present disclosure adopts the design of mutual limitation between the restraining roll 20 and the airbag bag 10, and can also make the easy-to-tear position of the restraining roll 20 correspond to the explosive deployment position 12 of the airbag bag 10, ensuring a better response when the airbag bag 10 is explosively deployed, and preventing the explosive deployment effect of the airbag bag 10 from being affected due to relative movement between the airbag bag 10 and the restraining roll 20 as the vehicle moves.

[0037] In some embodiments, the locking structure 11 includes a pair of locking positions 11 ′, the notch structure 22 includes a pair of notches 22 ′, and the distance between the pair of locking positions 11 ′ is smaller than the distance between the pair of notches 22 ′.

[0038] The design of the pair of latches 11' engaging the pair of notches 22' effectively prevents relative rotation between the airbag bag 10 and the binding roll 20. Furthermore, the distance between the pair of latches 11' is smaller than the distance between the pair of notches 22', effectively preventing relative displacement between the airbag bag 10 and the binding roll 20. This ensures stable binding of the airbag bag 10 by the binding roll 20.

[0039] In some embodiments (see FIG. 1 to FIG. 3 ), the airbag bag 10 or the restraining roll 20 is provided with a T-shaped notch, with a pair of latching positions 11 ′ formed on both sides of the T-shaped notch; the restraining roll 20 or the airbag bag 10 is provided with a pair of strip-shaped notches 22 ′.

[0040] 1 to 3 , the T-shaped notch is shown in the airbag bag 10 and the strip-shaped notch 22 ′ is shown in the restraining roll 20 , but the present invention is not limited thereto. In other embodiments, the T-shaped notch may be shown in the restraining roll 20 and the strip-shaped notch may be shown in the airbag bag 10 .

[0041] A pair of flippable latches 11' are formed on either side of the T-shaped notch. When the binding roll 20 is placed on the airbag bag 10 and moved to the strip-shaped notch 22', the latches 11' are flipped and snapped into the corresponding notches 22'. Because the pair of latches 11' snap into the pair of notches 22', and the distance between the pair of latches 11' is smaller than the distance between the pair of notches 22', the binding roll 20 and the airbag bag 10 are restricted from displacement in the axial direction Z and rotation in the circumferential direction R. This ensures that the binding roll 20 and the airbag bag 10 are mutually restrained, ensuring that the binding roll 20 stably binds the airbag bag 10.

[0042] In some embodiments (see FIG. 4 to FIG. 6 ), the airbag bag 10 or the restraining roll 20 is provided with a pair of U-shaped cutouts, and the corresponding portions of the U-shaped cutouts form the latching positions 11 ′; the restraining roll 20 or the airbag bag 10 is provided with a pair of U-shaped notches 22 ′.

[0043] 4 to 6 illustrate that the U-shaped cutout is provided on the airbag bag 10 and the U-shaped notch 22 ′ is provided on the binding roll 20 , but the present invention is not limited thereto. In other embodiments, the U-shaped cutout may be provided on the binding roll 20 and the U-shaped notch may be provided on the airbag bag 10 .

[0044] A pair of U-shaped cutouts form a pair of retractable latches 11'. When the binding roll 20 is placed on the airbag bag 10 and moved to the U-shaped notch 22', the latches 11' are flipped and snapped into the corresponding notches 22'. Because the latches 11' snap into the notches 22', and the distance between the latches 11' is smaller than the distance between the notches 22', the binding roll 20 and the airbag bag 10 are restricted from displacement along the axial direction Z and rotation along the circumferential direction R. This ensures that the binding roll 20 and the airbag bag 10 are mutually restrained, ensuring that the binding roll 20 stably binds the airbag bag 10.

[0045] In some embodiments, the airbag 10 is connected to a pair of lugs 16, with the retaining structure 11 or the notch structure 22 located between the lugs 16. The lugs 16 are used to mount the airbag on a vehicle body component. The retaining structure 11 located between the lugs 16 provides structural stability for the entire airbag 10.

[0046] In some embodiments, the restraining roll 20 is provided with a tearing portion 26 , and the tearing portion 26 corresponds to the bursting deployment portion 12 of the airbag 10 .

[0047] The tearing portion 26 is the easily tearable location of the restraining roll 20. By designing the restraining roll 20 and the airbag bag 10 to mutually limit each other, the tearing portion 26 of the restraining roll 20 can be aligned with the explosive deployment portion 12 of the airbag bag 10, ensuring a better response during explosive deployment of the airbag bag 10 and preventing the airbag bag 10 and the restraining roll 20 from relative movement with the vehicle, which could affect the explosive deployment effect of the airbag bag 10.

[0048] In some embodiments, the radial dimension of the binding roll 20 is smaller than or equal to the radial dimension of the airbag bag 10. In this way, the binding roll 20 can effectively and stably bind the airbag bag 10.

[0049] An embodiment of the present disclosure further provides a curtain airbag (CAB), which is configured with the airbag assembly described in any of the above embodiments.

[0050] The curtain airbag assembly, equipped with the aforementioned airbag bag assembly, can conveniently and effectively bundle the airbag bag 10 via the tie roll 20, utilizing a design where one is provided with a latching structure 11 and the other with a notch structure 22, with the latching structure 11 snapping into the notch structure 22. This design facilitates operation, saves assembly time, and improves installation efficiency. It also prevents the airbag bag 10 and the tie roll 20 from rotating, shifting, or other relative movement that could cause the airbag bag 10 / tie roll 20 to become loose, thus achieving stable bundling of the airbag bag 10. Furthermore, the design where the tie roll 20 and the airbag bag 10 are mutually restrained allows the easy-to-tear position of the tie roll 20 to align with the explosive deployment portion 12 of the airbag bag 10, ensuring a more responsive airbag bag 10 during explosive deployment and preventing relative movement between the airbag bag 10 and the tie roll 20 as the vehicle moves, which could affect the explosive deployment of the airbag bag 10.

[0051] The airbag assembly disclosed herein can also be applied to other types of safety airbags, such as driver / passenger seat airbags, front and rear side airbags, knee airbags, etc., and can achieve stable bundling of the airbag bag 10 through the cooperation of the binding roll 20 and the airbag bag 10, ensuring the stability of the airbag bag 10 under normal conditions and its explosion and deployment when needed.

[0052] The above content is a further detailed description of the present disclosure in conjunction with specific preferred embodiments, and the specific implementation of the present disclosure should not be considered to be limited to these descriptions. For those skilled in the art of the present disclosure, without departing from the concept of the present disclosure, several simple deductions or substitutions can be made, which should be considered to fall within the scope of protection of the present disclosure.
