に車室側に展開するようになっている。As shown in FIGS. 5 and 6, in this airbag device, an airbag cover insert 64 is integrally formed in the instrument panel 60, and the instrument panel 60 and the airbag cover insert 64 are made of foamed material. It is covered by a layer 66 and a skin 68. In addition, a horizontally single-shaped thin wall portion 74 is formed in the deployment portion of the air bag cover 70, and when the air bag body 72 is deployed, the air bag cover 70 breaks along this thin wall portion 74, and the air bag The cover 70 is configured to expand toward the vehicle interior together with the airbag body 72.

い見栄えが悪いという問題点を有していた。Now, if we consider the case where the above technology is applied to an instrument panel made only of resin material, which has become popular in recent years, and in which an airbag device is installed, it is possible to integrate the resin instrument panel and the airbag cover insert. In this case, in order to smoothly deploy the airbag cover, it is preferable to provide through holes intermittently along the break line of the portion of the resin instrument panel that will become the airbag cover. However, when the above structure is adopted, there is a problem in that the through hole is exposed on the interior side of the instrument panel, resulting in poor appearance.

貫通孔２２に沿って瞬時に破断す′る。When the vehicle body 10 is decelerated to a predetermined value or more, the acceleration sensor is activated and gas is generated from the inflation flakes 50. This gas passes through the shock absorbing member 52 and fills the airbag body 46. This gas pressure causes the airbag body 46 to start inflating. In this case, the airbag cover 62 of the instrument panel 16 is
0 is pressed toward the passenger compartment, and the instrument panel 16 instantly breaks along the through hole 22.
これによって、エアバラ夛袋体４６はケース２６の開口
部３８から乗員方向へ展開し、乗員を保護する。As a result, the air bubble bag 46 is expanded from the opening 38 of the case 26 toward the passenger, thereby protecting the passenger.

向上する。Further, in a normal state, since the sealing member 24 is fused to the compartment side portion of the airbag cover portion 20, the appearance quality of the instrument panel 16 is not impaired by the through hole 22. It can give a soft feel. Furthermore, by fusing the sealing member 24 made of a foam layer (for example, styrene elastomer) to the airbag cover part 2D formed of a resin material, the airbag cover part 20 can be attached to the airbag cover part 20 without using an adhesive. The sole member 24 can be attached, and the airbag cover 820 can have a soft feel. Furthermore, the impact absorption ability of the airbag cover n20 of the instrument panel 16 is further improved.
