Problems solved by technology
[0003] Since the guide structure (RAMP) 3 is mostly designed with TPO plastic material, it is impossible to see through the internal structure of the easily rotatable area 6 of the airbag, and the easily torsion part of the airbag 4 is blocked. Therefore, during the assembly process of the air curtain assembly, the airbag 4 is twisted risk and cannot be found, resulting in the air curtain in the event of a collision, the rotating air bag 4 cannot be fully deployed, unable to play a role in protecting the occupants

Embodiment Construction
[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0021] Please see attached figure 2 , an inspection method for preventing a curtain airbag from twisting, comprising the steps of:
[0022] Step 1: Set a visible groove 31 on the guiding structure (RAMP) 3 , which is located in the easily rotatable area 6 of the airbag. Preferably, the visible groove 31 is a U-shaped groove, and the installation state of the airbag 4 in the easily rotatable area 6 of the airbag can be seen.
[0023] Step 2: Set the detection ink dot 41 at the connection between the air bag 4 and the hanging ear 5, so that the detection ink dot 41 of the air bag 4 is located in the visible groove 31, which optimizes manual visual inspection and improves the convenience of inspection. The air bag 4 is twisted when installed, and the detection ink dot 41 will move out of the visible groove 31 as the twisted part rotates. Prefe...

The invention discloses an inspection method for preventing the twisting of a curtain airbag, comprising the following steps: Step 1: setting a visible groove (31) on the guide structure (3), located in the easy-to-rotate area (6) of the airbag; Step 2: Set the detection ink point (41) at the connection between the air bag (4) and the hanging ear (5), so that the detection ink point of the air bag is located in the visible groove; Step 3: After the air bag is installed, detect whether the detection ink point is In the visible slot, if yes, the air bag is not twisted, if not, the air bag is twisted. The detection method for detecting and detecting ink dots is at least one of manual visual inspection and infrared ink dot sensor detection. The invention visualizes the easy-to-rotate area of the airbag by slotting, which is convenient for manual visual detection of whether the airbag is twisted, and can also cooperate with mechanical detection. The double detection can ensure the accuracy of the inspection and can completely prevent the risk of the airbag being twisted during the assembly process , to ensure the safety performance of the curtain airbag assembly.
Description
technical field [0001] The invention relates to an assembly process of an automobile curtain airbag, in particular to an inspection method for preventing the curtain airbag from twisting. Background technique [0002] At present, most of the automotive curtain airbags on the market are designed to protect two or more rows of passengers, please refer to the attached figure 1 , due to the long length of this kind of air curtain, the curtain airbag of the prior art will add a guiding structure (RAMP) 3 on the air curtain to increase the guiding effect when the air curtain is deployed, and the hanging ear 5 is sewn on the air bag 4, and the hanging ear 5 is hung When on the generator bracket 1, the hanging lug 5 can be hung on the generator bracket 1 by rotating 360° clockwise or counterclockwise along the airbag 4. [0003] Since the guide structure (RAMP) 3 is mostly designed with TPO plastic material, it is impossible to see through the internal structure of the easily rotat...
