Abstract

An air bag case includes: a bottom wall portion including a bottom wall configuring portion; a side wall portion including a side wall configuring portion, wherein: the side wall configuring portion is bent so as to rise from an outer circumferential edge of the bottom wall configuring portion of the single metallic sheet material; a plurality of joining piece portions, provided on the side wall configuring portion, are superposed on corresponding joined portions to be crimped together to thereby maintain a rising shape of the side wall portion from the bottom wall portion; and the joining piece portions are disposed substantially parallel to the bottom wall portion together with the joined portions and are superposed on the joined portions so that the joining pieces portions and the joined portions are partially crimped together in a direction which is substantially at right angles to the bottom wall portion.

Description

technical field [0001] The present invention relates to a substantially box-shaped airbag housing, which has a bottom wall and a substantially cylindrical side wall rising from the outer peripheral edge of the bottom wall, and the airbag housing is configured not only to accommodate The airbag is folded, and when the airbag is inflated, the airbag is allowed to protrude from the upper opening thereof. Background technique [0002] Some conventional air bag housings have a structure in which, in a single metal plate, the side wall constituting portion constituting the side wall portion is bent so as to stand up from the outer peripheral edge of the bottom wall constituting portion constituting the bottom wall portion, and so that the A plurality of bonding pieces on the wall forming portion are superimposed on the corresponding bonded portion, so that the bonding piece and the bonded portion are crumpled together, thereby maintaining the standing shape of the side wall from t...
