Abstract (en)
An inflatable gas bag having auxiliary gas pockets is compose of a plurality of gas pocket units, each of gas pocket units includes a main gas pocket of bigger width and a plurality of auxiliary gas pockets of smaller width. A welding line is located between a main gas pocket and a auxiliary gas pocket, and between two auxiliary gas pockets. The conduits are arranged on said welding lines in a predetermined distance, through which gas in the main gas pocket and a plurality of auxiliary gas pockets can be transferred. The gas pocket units are isolated such that gas can not be transferred between each other. In case any main or auxiliary gas pockets are broken, gas could still be contained in other gas pockets. The present invention provides a plurality of auxiliary gas pockets to absorb the pressurized gas from main gas pocket during impact and therefore be able to protect articles from exterior impact more effectively.
