Safety is of utmost importance when it comes to automobile manufacturing, especially when it comes to protecting passengers in the event of a collision. To this end, the passive safety system plays a critical role in minimizing injuries. The airbag system is a key component of this system, and manufacturers are constantly striving to improve its effectiveness. This particular study examines the pressure, volume, and reaction time of two airbag folding methods—thin fold and spiral fold. The results indicate that the spiral fold method offers faster volume stability, while the pressure and temperature difference is only marginally affected (about 0.6%). The goal of this research is to gather input and feedback to determine the most optimal folding method, with the spiral fold method being the primary focus.

摘要

Safety is of utmost importance when it comes to automobile manufacturing, especially when it comes to protecting passengers in the event of a collision. To this end, the passive safety system plays a critical role in minimizing injuries. The airbag system is a key component of this system, and manufacturers are constantly striving to improve its effectiveness. This particular study examines the pressure, volume, and reaction time of two airbag folding methods—thin fold and spiral fold. The results indicate that the spiral fold method offers faster volume stability, while the pressure and temperature difference is only marginally affected (about 0.6%). The goal of this research is to gather input and feedback to determine the most optimal folding method, with the spiral fold method being the primary focus.
