Is determined by a control device including a CPU or the like, and when the impact force is determined to be equal to or greater than the set value, the inflator is operated by a signal output from the control device to generate a predetermined gas. By supplying the air bag, the air bag is rapidly inflated and deployed. That is, when the airbag is inflated and deployed, the deployment opening pressure of the instrument panel cover (hereinafter referred to as the interior cover) including the reinforcing plate is pressed from the inside by the deployment pressure, so that the fracture opening is broken along the fracture groove. And is partially separated from the interior cover, and the separated open portion is opened outward of the interior cover with the hinge portion of the reinforcing plate as a fulcrum. At the same time, the airbag is further inflated and deployed to the outside of the interior cover from the opening formed by the opening of the break opening, and the airbag inflates and cushions the occupant's chest such as the passenger seat. By supporting the head, the occupant is protected from the impact force in the event of a vehicle collision.

ある。However, in the above-described conventional airbag device for a vehicle, when the break opening portion 1 of the interior cover 9 is broken from the break groove by the inflation and deployment of the airbag and opened, the reinforcing plate material is used. Since the hinge part 3 and the case supporting member 10 are bent as shown in FIG. 3, the reaction force generated when the hinge part 3 and the case supporting member 10 are bent causes the support piece of the supporting member 6 to be bent. 6B, the supporting member fixing portion 9 of the instrument panel cover 9 into which the tapping screw 8 is screwed.
B, the support member fixing portion 9B is broken and separated from the interior cover 9. As a result, the reinforcing plate 2
The opening operation of the break opening portion 1 including the above becomes unstable, which may hinder inflation and deployment from the opening 9A of the airbag.

The protruding end is heated and melted and swaged to form a united structure. In particular, the reinforcing plate 2 is made of an integral metal plate, while the interior cover is made of a synthetic resin material such as polypropylene. Because the two components are composed of resin molded products, the coefficients of linear expansion of the two materials are different, and if the temperature inside the vehicle rises, such as during summer, or in cold regions, the temperature inside the vehicle may rise. 110 ° C when temperature rises, minus 35 ° C when temperature falls
Before and after, a considerable temperature difference occurs and the interior cover 9
The reinforcement plate 2 welded to the back surface of the break open portion 1 is deformed by warping or the like due to elongation or shrinkage of the material, and the welded portion with the back surface of the break open portion 1 is not peeled off. The breakage along the breaking groove of No. 1 is hindered.
In addition to the opening operation of the reinforcing plate member 2 with the fulcrum as a fulcrum, the opening of the opening 9A after the break open portion 1 is broken may have a crack or the break open portion may be scattered in the worst case. There's a problem.

される。Next, a description will be given of a case where a break opening portion 30 is formed in the interior cover 21 facing the housing portion 23. When forming the contour portion 30a and the divided portion 30b of the break open portion 30 that breaks when the air bag 27 is inflated and deployed on the interior cover 21, a known laser generating means (not shown) forms a predetermined frequency, for example, a 7 kHz pulse. A laser (output = 3 to 5 kW) is generated intermittently at a constant cycle, and this laser is generated from the back side of the interior cover 21.
Irradiation is performed while relatively moving at a predetermined speed along the outer edge of the reinforcing plate member 33 fixed to the back surface. As a result, a broken groove-shaped fragile portion is formed on the interior cover 21 according to the relative moving speed and the laser generation pattern from the laser generation means.

The airbag case further includes an airbag case that accommodates the airbag that is inflated and deployed by gas from the inflator disposed in a folded state and that has an opening at a location facing the back surface of the interior cover. An airbag device for an automobile, comprising: a rupture-opening portion having a fragile portion formed by a rupture groove at a back surface position of the interior cover facing the opening of the vehicle; and a reinforcing plate material having a shape corresponding to the rupture-opening portion. A horizontal body portion for fixing the plate material by welding to the back surface of the breaking open portion, and an attachment portion formed by bending the horizontal body portion via a hinge portion, and forming deformation absorbing means at least in the horizontal body portion. Even if it is a metal reinforcing plate material with a different expansion coefficient from the material of the break open part of the interior cover, temperature Can be smoothly released without any hindrance due to the occurrence of warpage, etc., and there is a gap between the open-break portion and the reinforcing plate, or the open-break portion and the reinforcing plate Does not rupture at the welded portion and the scattered open portion does not scatter. In addition, since the deformation of the reinforcing plate is suppressed, a reinforcing structure for suppressing the deformation can be omitted, and there is an effect that parts can be manufactured at low cost.
