In this case, an airbag is used for an instrument panel (instrument panel), a door trim, or the like. The air conditioner is installed inside a synthetic resin interior member, and swells into the vehicle compartment from an airbag inflation outlet provided in the interior member. Usually, the airbag inflation outlet is closed by a lid (airbag cover) having a thin portion that easily breaks when the airbag is inflated.

７２となっている。[0003] In order to prevent the airbag cover from breaking into pieces when the airbag is inflated, physical characteristics such as required flexibility and tensile strength are different from those of instrument panels and the like. For this reason, conventionally, an airbag cover is manufactured separately from an instrument panel made of a hard synthetic resin material, etc.
The opening of the airbag inflation outlet is covered with screws or the like. An example is shown in FIG. 10, which is an exploded perspective view of the passenger seat side portion of the instrument panel 1 '. In FIG. 10, a substantially square airbag inflation opening 13 is formed on the upper surface of the instrument panel 1 ′, and its opening peripheral wall 14 protrudes into the instrument panel 1 ′, and the front peripheral wall 141 of the opening peripheral wall 14 has a wall surface. Are provided with a plurality of mounting holes 15. The airbag cover 7 for closing the airbag inflation opening 13 has a substantially square shape in which the cover body 71 follows the airbag inflation opening 13, and its front side is bent downward at a right angle to form a rectangular connecting piece 72. ing.

Is inserted into the airbag inflation opening 13, the cover body 71 closely contacts the inner periphery of the opening of the airbag inflation opening 13 and closes it. The mounting hole 73 of the connecting piece 72 is located on the front side wall portion 14.
In this state, a metal retainer 8 having a U-shaped cross section provided with a similar mounting hole 81 is placed on the connecting piece 72 and the front side wall 141 from below, and the mounting hole 8 is formed.
These are joined together by bolts penetrating into one. When an unillustrated airbag installed in the airbag inflation opening 13 is inflated, the cover body 71 of the airbag cover 7 pivotally opens upward with the boundary between the airbag cover 7 and the connecting piece 72 as a hinge. At this time, an upward pulling force acts on the cover body 71, but the connecting piece 72 is attached to the front side wall 1 of the airbag inflation opening 13.
41 is connected to the airbag cover 7 by bolts.

If the airbag cover 7 and the airbag cover 7 are separated from each other as in the related art, it takes time to manufacture and assemble. For this reason, it is conceivable that these are integrally formed by two-color molding or the like. In this case, a structure for reliably preventing the airbag cover from scattering is required.

Further, the entire outer peripheral surface of the airbag cover 2 is stepped lower, and a concave groove 22 is formed between the outer peripheral surface and the peripheral surface of the opening of the airbag inflation opening 12. On the back surface of the front side (left side in FIG. 2) of the airbag cover 2, a plate-like rib 23 having a constant thickness is formed which extends along the same and projects linearly obliquely forward. A bracket 5 as a connecting member to be described later is connected. The bracket 5 reaches the airbag case 3 in which the airbag is stored.
The airbag case 3 is fixed to the insert 13 of the instrument panel body 11 via a bracket 31 with bolts 43 and nuts 44.

エアバッグカバー２の飛散が確実に防止される。The connection between the rib 23 and the bracket 5 is performed by connecting the mounting holes 61 and 51 of the retainer plate 6 and the bracket 5 to the rib 23.
Of the mounting holes 61,
This is performed by inserting a bolt 41 (FIG. 2) through 51 and tightening it with a nut 42. At the time of this tightening, the projections 52 formed on the plate surface of the tip end 54 of the bracket 5 bite into the plate surface of the rib 23 made of a synthetic resin material. When the airbag is activated, as described above, the thin portion 24 (FIG. 1) is broken with the inflation of the airbag, and the airbag cover 2 is pivotally opened into the vehicle cabin around the base of the rib 23 as a hinge center. Is done. At this time, the heat of the inflator in the airbag case 3 is transmitted to the airbag cover 2 to soften the synthetic resin material, and at the same time, an upward pulling force acts. Here, the projections 52 of the bracket 5 bite into the ribs 23 of the airbag cover 2 and are connected to each other. Therefore, even if the synthetic resin material is softened at this portion, the ribs 23 are formed.
Does not come off the bracket 5. This allows
The scattering of the airbag cover 2 is reliably prevented.

For example, the projections 52 are linearly arranged at the left and right positions of the mounting hole 51 as shown in FIG. As described above, the mounting holes 51 may be surrounded and arranged in a horseshoe shape. The shape of the projection 51 is not limited to the first embodiment as long as it easily penetrates the synthetic resin material of the rib 23, and may be, for example, a wedge shape. Furthermore, the number of the projections 51 is determined by design according to the use situation, and is not limited to the number of the first embodiment. In the first embodiment, an instrument panel has been described as an example of a synthetic resin interior member, but a door trim or the like may be used.
Instead of fixing the base end of the bracket 5 to the airbag case, the bracket 5 may be fixed to a structural member on the instrument panel side or the door trim side.
