両側に装備される。(Prior Art) As a conventional air bag device of this type, there is one as shown in FIG. 4 (partial cross-sectional view), which includes a module cover 1 and a module cover fixture 2 which are capable of emergency break deployment.
The folded air bag 4 is enclosed in the closed space A constituted by the inflator 3 for generating inflation gas. Vehicle collision Conventionally, a collision detector (not shown)
The inflator 3 receiving the signal injects a large amount of gas instantly from the gas discharge port 3a to inflate the air bag 4. The airbag 4 that has started to inflate rapidly breaks and deploys the module cover 1, continues to inflate, and inflates into a thick disk shape to absorb the impact of the occupant. Such a conventional airbag device is assembled and attached to the vehicle by the following procedure. First, the air bag 4, the ring plate 5, and the inflator 3 are tightened and fixed to the module cover attachment 2 with the assembly bolt 6. And the air bag 4
Is folded into a shape that allows rapid expansion and expansion, and is folded as small as possible, and the module cover 1 is covered from above. Then, the fixing member 10 (blind rivet in this figure) is inserted from the outside of the module cover 1 through the washer 9,
The module cover 1 and the module cover fitting 2 are firmly fixed by plastically deforming the tip of the body center of the fixing member 10 after penetrating the inside of the module cover fitting 2. After that, the air bag device is attached to the vehicle-side fixture 8 with the attachment bolt 7. The protective cover 11 is mounted on the vehicle side.
