うに、該バッグ展開ガイド８の反力をチューニングする
必要があって、この反力を適切にチューニングすること
は中々困難でもある。Due to the presence of the bag deployment guide 8, the airbag body 3 does not deploy in the instrument panel 1 or the opening 2 is broken when the airbag unit 3 is activated, and the airbag is not damaged. The grid 9 can be rotated upward to properly inflate and deploy into the vehicle compartment through the opening 2. However, since the bag unfolding guide 8 is formed of a metal plate, it is necessary to tune the reaction force of the bag unfolding guide 8 so as not to impair the impact energy absorbing effect of the instrument panel 1. Tuning the force properly can be difficult at times.

う。In addition to the reaction force tuning of the bag unfolding guide 8 as described above, the air bag unit 8 is positioned so that the bag unfolding guide 8 is out of the secondary collision area a of the instrument panel 1 for safety. 3 must be provided, and the layout of the airbag unit 3 in the instrument panel 1 is restricted.

はない。Since the cloth bag expansion guide is shaped by the wire, the expansion direction of the bag main body can be properly restricted to the opening direction when the bag main body is inflated. Further, when a collision load acts on the bag deployment guide, the bag deployment guide does not generate a reaction force because it is only shaped by the wire.

グカバー１４で包覆してある。1 to 4, reference numeral 10 denotes an air bag unit. The air bag unit 10 has an inflator 12 fixedly mounted on a base plate 11, and the inflator 12 is enclosed to attach a bag body 13 to the inflator 12. With the bag body 13 folded, the inflator 12 and the bag body 13 are covered with an air bag cover 14 made of a resin material.

A rectangular tubular shape is maintained by the ridges of the boundaries a, 15a, ... And the wire rods 16a and 16b inserted into the bag-shaped portion 15b formed on the upper open peripheral edge.

して上方へ回動し得るように取り付けてある。In this embodiment, the above-mentioned airbag unit 10 is arranged below the opening 2 formed in the instrument panel 1 so as to be in close proximity to the bag deployment guide 15. An airbag bag grid 17 is provided in the opening 2 at the upper edge side thereof. It is attached so that it can rotate upward as a rotation fulcrum.

ることはない。According to the structure of the above embodiment, when the inflator 12 is ignited and the bag body 13 is inflated and deployed at the time of collision of the vehicle, the bag deployment guide 15 is formed by the wire 16 even if it is made of cloth. The deployment guide direction is fixed in the opening 2 of the instrument panel 1, and
The inflation pressure of the bag body 13 acts substantially evenly in the radial direction of the bag deployment guide 15, so that the deployment guide direction does not change.

展開させることができる。Therefore, the bag main body 13 is guided by the bag deployment guide 15 to deploy toward the opening 2, and the inflation pressure causes the air bag grid 17 to flip up and rotate as shown by the chain line in FIG. It can be properly deployed into the vehicle compartment from the opening 2.

自由度を高めることができる。On the other hand, since the bag unfolding guide 15 is made of cloth as described above, it is merely shaped by the wire rods 16a, 16b arranged on the ridges of the four side faces 15a, 15a, ... And on the upper open peripheral edge. When a collision load is applied, since the wire rods 16a and 16b are flexibly deformed and hardly generate a reaction force, the bag deployment guide 15 causes the secondary collision of the instrument panel 1 as shown in FIG. Even if it exists in the area a, the collision energy absorption effect of the instrument panel 1 is not impaired even slightly, and therefore the flexibility of the layout of the airbag unit 10 can be increased.

の自由度を高めることができる。As described above, according to the present invention, since the bag deployment guide is made of cloth and the shape is retained by the wire, it can be sufficiently functioned as the deployment guide of the bag body, and of course, the collision can be achieved. When a load is applied, the wire rod flexes and deforms flexibly and hardly produces a reaction force. Therefore, there is no need to tune the reaction force of the bag deployment guide and the flexibility of the layout of the airbag unit. Can be increased.
