Below in conjunction with the accompanying drawing introduction, the formation of the present invention and the specific embodiment.
The present invention includes, constitute the outside air bag 10 of side airbag outside; Be positioned at the inboard air bag 20 of air bag 10 inboards, the outside; For from inboard air bag 20 air bag 10 supply gas laterally, the gas supply part 21 that forms at the outer periphery face of inboard air bag 20.
The outside air bag 10 that constitutes above-mentioned side airbag outside is when running into the collision accident, through the air feed expansion of gas generator 30, and the outside air bag 10 of protection driver and conductor safety, traditional side airbag is most of just to be made up of outside air bag 10.But the inside of the present invention's air bag 10 in the outside also comprises inboard air bag 20, accomplishes through two steps when opening side airbag.
The inboard that above-mentioned inboard air bag 20 is included in outside air bag 10 forms, and not only can be integrally formed with outside air bag 10, can also the inside of air bag 10 formation in the outside separately.
Above-mentioned inboard air bag 20 is positioned at the inboard of outside air bag 10, when gas generator 30 air feed, takes the lead in expanding, and penetrates seat webbing with outside air bag 10 and ejects.
Above-mentioned inboard air bag 20 is positioned at the inside of outside air bag 10, so that the gas that gas generator 30 produces is to penetrating the direction supply that seat webbing ejects.
Traditional side airbag is when opening, and the high pressure gas that gas generator 30 produces and the orientation independent of air-bag deployment arbitrarily disperse, and can compare difficulty so penetrate seat webbing smooth opening side airbag.
When the side airbag among the present invention launches, take the lead in expanding the outside that makes side airbag assembly 1 eject seat webbing, smooth opening side airbag assembly 1, protection driver and conductor's safety by above-mentioned inboard air bag 20.
The outer periphery face of above-mentioned inboard air bag 20 forms gas supply part 21.The effect of gas supply part is, inboard air bag 20 expands and penetrates after seat webbing ejects, the top and the bottom supply gas of air bag 10 laterally, smooth opening side airbag.
Therefore, the expansion for can be through gas generator 30 air feed the time penetrates seat webbing, and the expansion direction of inboard air bag 20 is perpendicular to seat webbing.After penetrating seat webbing, pressure is during greater than certain level, and above-mentioned gas supply part 21 can be by open, laterally the upper and lower supply gas of air bag 10.
Above-mentioned gas supply part 21 can suture (sewing) be made and is formed, and after inboard air bag 20 expanded and penetrates seat webbing, suture was opened under the effect of above-mentioned air pressure, laterally air bag 10 supply gas.
