An airbag sealing structure, including: an airbag body; at least one opening portion, configured on the airbag body; at least one passage portion, configured inside the airbag body and positioned at one side of the opening portion, a diameter of the passage portion being smaller than 2.9 millimeters; at least one accommodation space far away from the side of the opening portion and configured on the passage portion; and at least one blocking portion, configured inside the accommodation space and positioned at one side of the passage portion. Thereupon, a pneumatic pump nozzle may be inserted in the opening portion of the airbag body to fill air into the airbag body, air will then enter the accommodation space through the passage portion to inflate the accommodation space; when the accommodation space is saturated with air, the airbag body will seal the passage portion; thereafter, the passage portions are hot-sealed immediately.

A force-attenuating system that is interposed between an exterior surface and an interior surface, either or both of which may be subjected to percussive forces. The system has a ceiling that is positioned proximate the exterior surface and one or more inverted hat-shaped force-attenuating units with sidewalls extending inwardly convergingly away from the ceiling. Some of the units have a floor that is positioned proximate the interior surface. Optionally the force-attenuating units may be configured as clover-leaf structures with a central region and hemi-pear-shaped lobes extending therefrom. Within the lobes is a floor that is positioned proximate the interior surface. The force-attenuating system may be deployed in an automotive or non-automotive environment.

A heat-seal apparatus of an air-bubble machine and the method thereof, comprising: an air-bubble machine main-body; at least one electromagnetic heating assembly for producing a magnetic force; at least one magnetically conductive heat-seal assembly to heat-seal at least one air-bubble film; at least one support-portion to make an interval space between the electromagnetic heating assembly and the magnetically conductive heat-seal assembly; and at least one transmission shaft-body. The magnetic force generated by the electromagnetic heating assembly passes through the interval space to mutually interact with the magnetically conductive heat-seal assembly by electromagnetic induction, and the magnetically conductive heat-seal assembly is heated in a non-contact manner to make the heating be very rapid and uniform. The magnetically conductive heat-seal assembly is driven by the transmission shaft-body to move the air-bubble film which is simultaneously heat-sealed when being moved, thereby improving the use efficiency of energy.
