Abstract: There is provided a side airbag for an automobile having airbag modules 100, 200, 300, which selectively includes reinforcing pads, an inner cushion pad, a tube-type tether and a tear seam, all of which are piled in multi-layers, so that the side airbag may be developed with regulating the gas pressure duration without eccentricity, in a useful and effective manner to successfully protect a driver and passengers seated in the vehicle. The cushion pads used in the side airbag require a small amount of materials, are easily seamed and easily folded, so as to reduce costs.

Abstract: Disclosed are a side airbag system, and manufacturing and folding methods of the side airbag system, by which a passenger's head and thorax can be safely protected, and manufacturing cost and labor can be reduced. The side airbag system has an airbag cushion and an inflator assembly. The airbag cushion has a first panel, a pair of second panels, and pairs of reinforcement panels. The airbag cushion has an upper chamber and a lower chamber partitioned by a tether. The inflator assembly has an inflator, a mounting ring, and a mounting bracket. The tether constantly maintains a pressure in and a shape of the airbag cushion so that a gas injected by the inflator is filled in the lower chamber prior to the upper chamber.
