Airbag device
First Claim
1. An airbag device comprising:
- a case configured to receive an airbag that is folded, and configured to enable the airbag under inflation to protrude from an upper opening, the case having a substantially box shape, and including a bottom wall portion and a side wall portion that rises in a substantially tubular shape from a peripheral edge of the bottom wall portion;
a fixing member; and
a coupling member surrounding the case and coupled to the case by the fixing member, wherein;
the case is formed to retain a rising shape of the side wall portion from the bottom wall portion byperforming a bending process on a sheet metal material such that side wall components constituting the side wall portion rise from a peripheral edge of a bottom wall component constituting the bottom wall portion in the sheet metal material, andsuperimposing and coupling a joining piece portion formed in a front or rear wall component on and to a corresponding joined portion formed in one of the side wall components; and
the joining piece portion in the case and the joined portion corresponding to the joining piece portion include through-holes which are penetrated by the fixing member, respectively, and are coupled to each other and are coupled to the coupling member using the fixing member penetrating the through-holes of the joining piece portion and the joined portion in a state in which the joining piece portion and the joined portion are superimposed on each other.
