Inflatable gas bag having auxiliary gas pockets

Abstract

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 an 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 units. 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.

       9 . An inflatable gas bag having auxiliary gas pockets comprising 
 an upper film    a lower film;    a plurality of gas pocket units which are isolated so that gas can not be transferred between each other, and side by side between each, and consist of a main gas pocket and a plurality of auxiliary gas pockets;    a welding line having conduits sat between main gas pocket and auxiliary gas pocket and between two auxiliary gas pockets;    a gas inlet on one side of the inflatable gas bag;    a gas channel extended from the gas inlet and connecting to each of main and auxiliary gas pockets , though which gas can be entered;    characterized in that the width of main gas pocket is bigger than that of auxiliary gas pockets, therefore the main gas pocket will be thicker than auxiliary gas pockets after charged with gas, the main gas pocket will absorb the impact and be compressed first, and the pressurized gas in the main gas pocket will be pressed into auxiliary gas pockets via conduit when the inflatable gas bag suffers from exterior impact.    
   
   
       10 . The inflatable gas bag having auxiliary gas pockets as defined in  claim 9 , wherein the width of main gas pocket is bigger than auxiliary gas pockets at least 1 centimeter.
