There is provided an airbag device being excellent in performance of protection of an occupant wherein a folded airbag () undergoes sequential and orderly expansion starting from a region where the expansion ought to be started. It is characterized in that a gas rectification member () for rectifying and guiding a gas generated from an inflator () up to the vicinity of a part of the airbag (), inflating in the initial stage of the expansion thereof, is provided substantially at the central part of the airbag ().

Airbag device

There is provided an airbag device for allowing a holding member to firmly hold an outer circumference part and a peripheral edge part of an airbag during the airbag assembling work and to reduce the assembling work time. The airbag device comprising a holding member () for holding an airbag () in a state as folded and contained therein, and pressing down a side face of the airbag () on the outer circumference thereof. The holding member () is made of a woven cloth, and an anticipated rupture part () to be ruptured by a gas generated from an inflator () is formed at the position corresponding to the part of the airbag (), inflating in the initial stage of the expansion thereof.

There is provided an airbag device being excellent in performance of protection of an occupant wherein a folded airbag () undergoes sequential and orderly expansion starting from a region where the expansion ought to be started. It is characterized in that a gas rectification member () for rectifying and guiding a gas generated from an inflator () up to the vicinity of a part of the airbag (), inflating in the initial expansion thereof, is provided substantially at the central part of the airbag ().

In an airbag device, a decorative member is prevented from being scattered with a simple structure at the time of expansion of an airbag. That is, a concave part of the airbag cover () on which the decorative member is mounted is connected to an unmoved connection member while freely separable from other portions at the time of expansion of an airbag. To that end, there are formed, on the inner faces of the airbag cover (), a circular tear line Lc for partitioning the concave part () and a plurality of tear lines Lextending outward from the tear line Lc in the radial direction thereof for forming each of opening pieces (). Further, attachment pieces () of respective opening pieces () are fastened to plastic deformable attachment parts of a base plate by screws. With this structure, the concave part of the airbag cover can be immovably held at the time of spread of the airbag.
