An airbag device includes an airbag, a case in which the folded airbag is housed, and an airbag cover that covers the folded airbag. An attachment portion of the airbag cover is attached to a peripheral wall portion of the case by a rivet being caused to pass through. The case is such that a vicinity of a boundary region between the peripheral wall portion and a bottom wall portion is curved in an approximate arc in cross-section. The attachment portion includes a protruding portion that protrudes toward the peripheral wall portion side in an end edge farther to a leading end side than a region of penetration of the rivet. The protruding portion is disposed in a position opposing a curved region configuring a boundary region between the peripheral wall portion and the bottom wall portion, and is protruded in such a way as to be oriented farther to a central side of the bottom wall portion than an outer side face of the peripheral wall portion, and an edge on the peripheral wall portion side of a protruding end face is disposed in a state of non-contact with the curved region.

An inflatable airbag system is disclosed, the inflatable airbag system configured with a securement wrapper and a packaging wrapper, the securement wrapper retaining an inflatable airbag cushion of the inflatable airbag system in a packaging state during assembly of the packaging wrapper to the inflatable airbag system. The securement wrapper prevents or reduces the incidence of excursion of the inflatable airbag cushion from the appropriate packaging state during assembly.

A driver seat airbag device, provided with a steering wheel and an airbag module. The steering wheel includes a variant rim with a central upper part thereof omitted, and a cover member that covers the module installation surface at the center of the rim and the airbag module. The cover member includes a frontal region on an occupant side of the airbag module, an upper region on the upper side of the airbag module, and a tear line that enables the frontal region and the upper region to open up as cover doors. The tear line extends continuously from at least the center of the frontal region to at least the center of the upper region. The cover doors open to the left and right respectively from near the center of the frontal region and upper region.

Airbag covers and related airbag modules designed with weakened portions configured to specifically accommodate emblems. In some embodiments, an airbag cover may comprise an emblem and a tear seam or another weakened portion extending through and/or adjacent to the emblem to create an asymmetrical split such that, following deployment and rupturing of the tear seam, the airbag cover is configured to form first and second airbag cover pieces, wherein a greater number and/or weight of the emblem is on the first airbag cover piece than the second airbag cover piece.
