| 20100215293 | AIR BAG WITH PRESSURIZATION SPACE - An air bag includes two inner sheets facing each other, two outer sheets located at an outer side of the two inner sheets, heat resistance material located at an inner side of any one inner sheet, a first thermal bonding line thermally bonding the two outer sheets to form air input channel, a second thermal bonding line thermally bonding the inner and outer sheets along the material with gap from the first thermal bonding line, and third thermal bonding lines extending from the second thermal bonding line oppositely to the air input channel to form air pillars, a second thermal bonding portion being formed to cross the third thermal bonding lines to thermally bond the two inner and outer sheets to form a pressurization space between the second thermal bonding portion and line, and the second thermal bonding portion being spaced apart from adjacent second thermal bonding portion to form a second passage. | 08-26-2010 |
