Airbag apparatus

An airbag apparatus mounted in a vehicle, comprising:

• an airbag folded and housed in a housing part of the vehicle, the airbag being including
• a gas introducing portion which inflates to separate an interior wall portion and an exterior wall portion from each other by introducing an inflating gas thereinto, the gas introducing portion including
• a gas supply passage portion which is extended along a longitudinal direction at an upper edge of the airbag so as to communicate with a connecting port portion connected to an inflator for supplying the inflating gas, and
• a plurality of parallel cells arranged substantially in parallel with each other in the longitudinal direction so as to extend downward, each of which has an inflating gas inlet port at an upper portion side thereof facing the gas supply passage portion;
• and
• a non-introducing portion which keeps the interior and exterior wall portions joined to each other so as not to allow the inflating gas to be introduced thereinto, the non-introducing portion including
• a peripheral portion which defines an outer peripheral edge of the airbag, and
• extending partitioning portions which extend upward from a lower edge portion of the peripheral portion to partition the parallel cells,
• wherein the parallel cells include a quick deployable cell which has a downstream side extending partitioning portion which locates at a downstream side in an inflating gas flow and an upstream side extending partitioning portion which locates at an upstream side in the inflating gas flow, so that the quid deployable cell is capable of deploying quickly.
