示されている。BACKGROUND ART FIG. 4 shows a conventional vehicle airbag device.
is a base plate, and an inflator 2 and a bag 3 are fixed to this base plate 1. Reference numeral 4 denotes a bag cover made of urethane for storing the bag 3 in a folded state, and is fixed to the peripheral flange la of the base plate l with bolts and nuts 6. This bag cover 4 has a scattering prevention member 5 such as a net or a resin film embedded inside the gap formed in the front wall except for the opening 4a. This similar structure is shown in, for example, Japanese Unexamined Patent Publication No. 58-38131.

るものである。Problems to be Solved by the Invention When the bag 3 is inflated and deployed by the ignition operation of the inflator 2, the bag cover 4 is torn from the eye 4a due to the expansion of the bag 3, prompting the rapid deployment of the bag 3. When the bag cover 4 breaks, scattered particles are generated that cannot be suppressed even by the scattering prevention member 5. In addition, since the scattering prevention member 5 is buried inside, it is difficult to mold the bag cover 4, resulting in an increase in cost. SUMMARY OF THE INVENTION Therefore, the present invention provides an airbag device having a bag cover that does not generate flying particles and is easy to mold.
課題を解決するための手段
バッグを収納するバッグカバーを布製とし、このバッグ
カバーをインフレータおよびバッグを固着したベースプ
レートの周縁部に接着固定してある。Means for Solving the Problems A bag cover for storing a bag is made of cloth, and this bag cover is adhesively fixed to the peripheral edge of a base plate to which an inflator and a bag are fixed.
作用 インフレークの点火作動によりバッグが膨張。action The bag inflates due to the ignition of the inflation flake.
展開する際に布製のバッグカバーは該バッグの膨張圧に

の背面に接着剤８により接着固定しである。In FIG. 1, a peripheral flange lb of a base plate l to which an inflator 2 and a bag 3 are fixed is bent and molded on the front side, and a cover shape-retaining frame IO made of a resin material is integrally molded onto this peripheral flange 1b. be. A bag cover 7 for storing the bag 3 in a folded state is made of cloth such as cloth or non-woven fabric, and the bag cover 7 is stretched around the cover shape-retaining frame 10.
It is adhesively fixed to the back side with adhesive 8.

断し、微粒子状に飛散することはない。Therefore, according to the structure of this embodiment, when the inflator 2 is ignited and the bag 3 is inflated and expanded during a vehicle collision, since the bag cover 7 is made of cloth, the cover is protected by receiving the inflation pressure of the bag 3. It will not peel off from the adhesive part on the back of the frame 10, or tear at the opening of the cover shape-retaining frame 1O, and will not scatter in the form of fine particles.

きる。In the embodiment shown in FIG.
a, and the periphery of the cloth bag cover 7 is pushed into this groove 10a and fixed with adhesive 8. In addition to the effects of the embodiment shown in FIG. , the cloth area of the bag cover 7 can be minimized.

の膨張、展開を速かに行わせる。Further, a peripheral flange la is formed on the base plate 1 by bending it toward the back side and being offset outwardly from the body portion 9,
Bolt the resin protective frame II to this peripheral flange Ia.
It is fixed with nut 6. The old edge of the folded portion 9a of the body portion 9 and the front edge of the protective frame Il are formed in a tapered shape,
Hold the bag cover 7 between these and
It is designed to add tension to the center of the fabric to improve its appearance. According to this embodiment, when the inflator 2 is ignited, the bag cover 7 is torn from the edge portion of the folded portion 9a, or the center portion is torn, and the bag cover 7 is torn from the edge portion of the folded portion 9a.
Expand and expand quickly.
この実施例の場合にあっても、バッグカバー７は布製で
