Embodiment Construction

[0058] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Fig. 1 is a longitudinal sectional view of an airbag device for a driver's seat in an embodiment, Fig. 2(a) is a perspective view of an airbag flattened before folding, Fig. (b) is a sectional view taken along line B-B of Fig. (a), Fig. 3 is the As an exploded view of the airbag device, FIG. 4 is a perspective view from above showing the folded airbag, and FIGS. 5 and 6 are perspective views from below and above of the folded airbag (before being surrounded by the shape maintaining member).

[0059] The airbag device 71 is composed of a stopper (base) 72, an airbag 73 mounted on the stopper 72 through an airbag mounting ring 74, an inflator 76 for expanding the airbag 73, and an airbag 73 that keeps the folded shape of the airbag 73. The shape maintaining member 80 and the module cover 75 which covers the airbag folded body are comprised.

[0060] The stopper 72 is provi...

Abstract

Provided is a driver airbag device with an airbag shape-maintaining component, wherein an inflator is readily mounted, an airbag device (71) is provided with a retainer (72), an airbag (73) mounted on this retainer (72) with an airbag-mounting ring (74), an inflator (76) to inflate this airbag (73), a shape-maintaining component (80) to maintain the shape of the folded airbag (73), a module cover (75) covering a folded-airbag unit, and the like. The shape-maintaining component (80) is fixed with bolts (85) and the like. The central portion of the shape-maintaining component (80) and the central portion of the front panel (73f) are seamed with a seam thread (80s). When an inflator (76) is mounted on an assembly of the folded-airbag unit and the retainer (72), since a space (S) is included in the inside of the folded-airbag unit, the front-end side of the inflator (76) is smoothly inserted.

Description

technical field [0001] The present invention relates to an airbag device for protecting occupants of a vehicle during a collision, and more particularly to an airbag device in which a folded airbag is held in shape by a shape holding member and assembled. Background technique [0002] Generally, an airbag device used as an occupant protection device in a vehicle or the like includes a folded airbag, an inflator for supplying gas to the airbag, a base and a housing on which these airbags and the inflator are mounted and fixed, and a bag pressure receiving member arranged in a An outer cover capable of covering the upper surface of a folded airbag and breaking due to the internal pressure of the airbag when the airbag device is activated. [0003] In such an airbag device, the folded shape of the airbag is held by the shape retaining member in order to improve the installation workability when the above-mentioned cover is attached and to prevent the deformation of the cover ca...
