As a preferred embodiment, the first inflatable space 12 is configured as an active inflatable space and the second inflatable space 22 is configured as a passive inflatable space. That is, the first inflatable space 12 will actively generate gas to automatically inflate, and the second inflatable space 22 will not automatically generate gas but will be filled with the gas generated in the first inflatable space 12. For example, the first inflatable space 12 has a gas generator therein, while the second inflatable space 22 does not have a gas generator therein.
Specifically, when the vehicle is impacted and the air curtain 100 starts to inflate, the air curtain body section 1 is inflated first, gas cannot enter the air curtain folding section 2 due to the blocking effect of the sewing line 3, and after the air curtain body section 1 is filled with gas, the pressure is increased, the sewing line 3 is broken, the gas enters the air curtain folding section 2, and the air curtain folding section 2 extends forwards to cover the vehicle A column 200 and the vehicle instrument panel, so that a driver and passengers are protected.
Therefore, the overall expansion of the air curtain 100 can be more regular, so as to avoid the mutual interference when the air curtain body section 1 and the air curtain folding section 2 are expanded, and further improve the overall stability of the air curtain 100.
As another preferred embodiment, the first inflatable space 12 and the second inflatable space 22 are both configured as active inflatable spaces. I.e., both the first inflatable space 12 and the second inflatable space 22 will actively generate gas to be inflated automatically. For example, a gas generator is provided in both the first inflatable space 12 and the second inflatable space 22.
From this, can make gas curtain body section 1 and gas curtain folding section 2 can inflate simultaneously to make the whole reaction inflation speed of gas curtain 100 faster, can take place the very first time of striking at the vehicle and react rapidly in order to protect passenger and driver, thereby further promoted the security of vehicle.
As shown in fig. 1, inflatable curtain folded section 2 is folded in a flat manner over inflatable curtain body section 1. Therefore, the folding section 2 of the air curtain can be more smoothly extended, and the overall extension speed of the air curtain 100 is ensured.
