Airbag packet, production method therefor, and airbag device

A method of forming an elongated airbag packet, the method comprising:

• placing an elongated airbag within a case so that a longitudinally extending side thereof extends along an elongated bottom surface of the case;
• inflating the airbag in the case;
• and
• generally uniformly pressing against the longitudinal side of the elongated airbag in the case for pressing the airbag against the elongated bottom surface to compress the airbag.

An airbag packet comprising:

• an airbag having an elongated side;
• material of the airbag defining an internal space of the airbag;
• and
• an aperture of the airbag through which gas is supplied to, and removed from, the airbag internal space, the airbag material generally being uniformly compressed in a direction transverse to the elongated side of the airbag for forming the airbag packet without regular folds in the airbag material and so that upon airbag deployment, gas supplied through the aperture flows smoothly into the airbag internal space for rapid airbag deployment.
