1. an airbag for opening is preset in gas column break over region, it is characterized in that, comprises:

  • One air column slice, this air column slice is made up of many vertical hot-sealing lines and many transversal heat seal lines multiple gas columns that then two adventitias are formed;

    Multiple point of transition, this point of transition is by sealing then those adventitias and being formed, and is arranged on those gas columns or those vertical hot-sealing lines;

    One turnover center line, is positioned on this air column slice, this transversal heat seal line parallel;

    Multiple node, is positioned at the both sides of this turnover center line, and and interval one predeterminable range between this turnover center line;

    Many side hot-sealing lines, post heat-seal of transferring in this air column slice along this turnover center line then transfer after the dual-side of this air column slice, wherein, those side hot-sealing lines extend to those nodes by one end of this air column slice, form a break over region not section of heat-sealing between those nodes and this turnover center line;

    Wherein, when after the inflation of this air column slice, this air column slice forms a bottom surface between those point of transitions, and this break over region not section of heat-sealing expansion forms an opening of sided polygons, and forms a bearing surface in the bottom of this opening.
