BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an instrument panel in which an airbag device is installed in an instrument panel of an automobile, particularly in an instrument panel on a passenger seat side of a passenger car.

[0002]

2. Description of the Related Art A conventional instrument panel structure of this kind is as shown in FIG. That is, 1
Is a steering member disposed on the back side of the instrument panel 2, a bracket 3 is fixed to the steering member 1 by welding means, and the bracket 3 is housed inside the instrument panel 2. The airbag unit 4 is held.

On the outside of the airbag unit 4, a support arm 7 for supporting an airbag grid 6 for closing an airbag inflating opening 5 formed in the instrument panel 2, and closing the airbag grid 6 is provided. A locking portion 8 for holding a state is attached,
For example, upon detecting an abnormal impact force due to a collision or the like of the vehicle body, the priming agent in the airbag unit 4 explodes, inflating the airbag, and the inflated airbag pushes up the airbag grid 6 as shown by a chain line to open the airbag. The section is bulged (projected) toward the occupant from the section to secure the occupant.

However, in the instrument panel having such a structure, an airbag grid 6 for closing the opening 5 for inflating the airbag is provided. And an airbag lid pad 10 attached to the surface of the airbag lid core 9.
0 is a separate member from the instrument panel pad 11 attached to the surface of the instrument panel 2, as shown in FIG. 2 between the air bag grid pad 10 and the instrument panel pad 11. A boundary (parting line) 12 is generated, and the aesthetic appearance of the entire instrument panel is impaired.

In order to solve this problem, FIG.
As shown in FIG. 1, in an instrument panel 21 in which an instrument panel core 22 and a skin 24 and a foam layer 23 are integrally formed between the core and the skin, a part of the core 22 is provided with an airbag. An opening 25 for swelling is provided, and a one-sided airbag lid member 27 provided with a blade 26 standing upright at an edge is connected and attached to the opening via a hinge portion 29, and the instrument panel An instrument panel in which an airbag case 34 in which an airbag unit 33 is housed inside is fixed by mounting screws 32 on the back side of the core material has been proposed.

[0006]

However, in the instrument panel having the seamless structure, the hinge portion 29 provided on the core member 22 has a shape curved toward the foam layer 23 side. When the instrument panel 21 is foam-formed using the core material 22, the foaming agent (urethane) leaks from both ends of the hinge portion 29 toward the back side of the core material 22, which causes a product defect. There was a defect.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems. In making the above-mentioned seamless instrument panel, the structure of a hinge portion provided on the air bag grid is improved. At the same time, an instrument panel that can improve the quality of products by using a core material that can hold a sealing material to prevent liquid leakage of the foaming agent at both ends of the improved hinge part. To provide.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the embodiments shown in FIGS. 4 and 5. The same parts of the structure of the present embodiment and the structure described in the conventional example are the same as those of FIG. The reference numerals used in the examples are attached, and the description of the same structural parts is omitted.

That is, the present embodiment is characterized in that a hinge portion 29 formed on an airbag lid member 27 for closing an airbag inflating opening portion 25 provided in a core material 22 constituting an instrument panel is formed. Is formed so as to protrude toward the rear side of the instrument panel 21, and the hinge portion 2 of the airbag lid member 27 is formed.
Each of the bag portions 35 for receiving the curved portions at both ends of the hinge portion 29 is integrally formed with the core member 22 for fixing the nine side edges by the mounting screws 32. Further, a seal member 36 made of, for example, a urethane foam sheet or the like for preventing liquid leakage is adhered to a gap formed between the inside of the bag portion 35 and the curved hinge portion 29.

More specifically, the present invention will be described in detail. An opening 25 for inflating an airbag is provided in a core material 22 constituting an instrument panel 21, and an opening 25 is provided at a position symmetrical to the periphery of the opening 25. A bag 35 is formed, and the opening 2
The airbag lid member 27 that closes the airbag 5 is formed with a hinge portion 29 that curves toward the back side of the instrument panel. At this time, a sealing material for preventing liquid leakage is interposed so that the curved portions at both ends of the hinge portion 29 enter the bag portion 35, and in a gap generated between the curved portion and the bag portion 35. After the core material and the preformed skin 24 are set in a foaming mold, a foaming agent is injected and foamed between the core material and the skin 24 to form the desired instrument. The result is a ment panel.

When the instrument panel thus obtained is subjected to foam molding, the bag portion 35 formed on the core member 22 is formed.
By the action of the curved hinge portion 29 entering the bag portion 35 and the sealing material 36 filled in the gap generated between the bag portion 35 and the curved hinge portion 29, a foaming agent for foaming the instrument panel. Does not leak to the back side of the core member 22 and a good quality instrument panel can be obtained.

[0012]

As described above, according to the present invention, the core member 22 having the opening 25 for inflating the airbag and the opening 25 are provided.
Airbag lid member 2 attached so as to close the airbag
7, a foam layer 23 formed on the upper surfaces of the air bag grid member 27 and the core material 22, and a skin 24 adhered to the surface of the foam layer 23, wherein the air bag grid member 27 A hinge portion 29 that curves in the direction of the back side of the core member 22 is formed on the core member 2.
2 is a bag 3 into which both ends of the hinge 29 are fitted.
5 is formed, and furthermore, since it is an automotive instrument panel in which a sealing material 36 is interposed in a gap generated between the bag portion 35 and the curved hinge portion 29, according to this, it is formed on the core material 22. When the instrument panel is foamed by the action of the bag portion 35, the curved hinge portion 29 entering the inside of the bag portion 35, and the sealing material 36 filled in the gap generated between the bag portion 35 and the curved hinge portion 29. This does not cause the foaming agent to leak to the back side of the core member 22, and an effect of obtaining an instrument panel of good quality can be obtained.
