[Industrial applications]

 The present invention relates to an instrument panel incorporating an automobile airbag device.

[0002]

[Prior Art]

 FIG. 5 shows an example of a conventional instrument panel with a built-in air bag device for automobiles (“E-KA7,” a service manual structure edition issued by Honda Motor Co., Ltd. in October 1990). Type ”).

That is, reference numeral 1 in the drawing denotes an instrument panel, including a panel main body 1a made of a synthetic resin material such as polypropylene composite material, and a pad 1b formed on the panel main body 1a and made of foam such as urethane foam. , An outer cover 1c made of polyvinyl chloride (PVC) or the like, which is arranged on the surface of the pad 1b and adhered when the pad 1b is formed, and is integrally formed below the instrument panel 1 with an airbag and an inflator. An airbag device 2 whose main component is is stored. An air bag ejection opening 3 is formed at a position of the instrument panel 1 facing the air bag device 2 so that the air bag inflated and expanded can be ejected when the air bag device 2 is operated. A lid 4 having the same configuration as the instrument panel 1 that covers the vehicle is provided. The lid 4 is supported by a step portion 3 a formed on the inner edge of the opening 3.

[0004]

[Problems to be solved by the device]

 However, in such a conventional structure, since a gap 4a between the opening 3 and the lid 4 is formed on the surface of the instrument panel 1, the appearance is poor and the appearance quality is deteriorated. In addition, since the lid 4 has a large variation in thickness due to the nature of its components, the lid 4 may be higher or lower than the instrument panel 1 surface (Fig. 5 shows an example of higher height). Not only does it look bad because the peripheral edge of the lid 4 or the inner edge of the opening 3 is visible as a knurled surface, but there is also the problem that it may be touched and scratched by children.

The present invention has been made in view of such conventional problems, and improves the appearance quality of the instrument panel and prevents damage to the instrument panel incorporating an automobile airbag device. The purpose is to provide.

[0006]

[Means for Solving the Problems]

 In order to achieve such an object, the present invention is an instrument panel having a panel body, a pad arranged on the panel body, and a skin formed on the surface of the pad, which is integrally formed and has an air bag device built therein. In the panel body, an airbag pop-out opening is formed at a position facing the air bag device so that the air bag that inflates and deploys when the air bag device is activated can be popped out, and a hinge is provided on one side of the opening. A lid covering the opening is openably attached via the pad, and the lid and the skin that protrude to bite into the pad and face each other when the lid opens are attached to the edges of the other three sides except the side to which the hinge of the lid is attached. It is a projecting cutter part that ruptures.

[Operation] During a vehicle collision, when the airbag device is activated and the airbag is inflated and deployed, the lid is opened by the pressing force of the airbag. As a result, the cutter part protruding from the lid ruptures the pad and the skin of the instrument panel facing each other, and a new airbag pop-out opening is formed at a position facing the air-bag pop-out opening. The airbag pops out through.

As described above, when the airbag device is actuated at the time of a vehicle collision, the airbag pop-out opening is formed on the front surface side of the instrument panel for the first time, and it is generally flush with no gap. ..

【Example】

 An embodiment of the present invention will be described below with reference to the drawings by attaching the same symbols to the same or equivalent parts as in the conventional example.

1 to 3, reference numeral 1 denotes an instrument panel, which is formed of a panel body 1a made of a synthetic resin material such as polypropylene composite material, and a foam body such as urethane foam disposed on the panel body 1a. The pad 1b and the skin 1c such as polyvinyl carbonate (PVC) formed by coating on the surface of the pad 1b are integrally configured.

The instrument panel 1 contains an airbag device 2 having an airbag 2a and an inflator 2b as main components. A rectangular air bag ejection opening 5 is provided at a position where the air bag device 2 in the panel body 1a of the instrument panel 1 is opposed to the air bag device 2 so that the air bag 2a inflated and expanded can be ejected when the air bag device 2 is activated. Are formed.

A lid 7 that covers the opening 5 is attached to the upper end side that is one side of the airbag ejection opening 5 so as to be openable and closable via, for example, iron hinges 6 and 6. The lid 7 is adapted to be opened by the airbag 2a which is inflated and deployed when the airbag device 2 is actuated. Further, the lid 7 is formed by cutting out from the panel body 1a or is made of the same material and is a separate body. Further, the hinges 6 and 6 are attached to the panel body 1a and the front surface side of the lid 7 so that the lid 7 opens only to the front surface side of the instrument panel 1.

A cutter portion 8 having a triangular cross-section that protrudes so as to bite into the pad 1b is provided at the end edges of the lid 7 on three sides other than the one side to which the hinges 6 and 6 are attached. When the pad is opened, the pad 1b and the epidermis 1c which face each other are ruptured. A notch 9 is formed on the inner edge of the opening 5 facing the cutter portion 8 to avoid interference with the lid 7.

Next, the operation will be described. In the event of a vehicle collision, when the inflator 2b of the airbag device 2 is activated and the airbag 2a is inflated and deployed, the pressing force of the airbag 2a opens the lid 7. As a result, the cutter portion 8 provided on the lid 7 ruptures the facing portion of the pad 1b and the outer skin 1c of the instrument panel 1, and a new airbag pop-out opening is provided at a position facing the airbag pop-out opening 5. Is formed. The inflated and expanded air bag 2a thus pops out through this opening and fulfills a predetermined cushioning function.

As described above, when the airbag device 2 is actuated in the case of a vehicle collision on the surface of the instrument panel 1, a pop-out opening of the airbag 2a is not formed for the first time, and normally no gap is formed and the surface is flush. Therefore, the appearance is very good and the appearance quality is improved.Because there are no edges, the nails do not get scratched, the instrument panel is not scratched, and the structure is extremely simple and inexpensive. It

FIG. 4 shows another embodiment of the present invention. In this embodiment, the lid 7 is formed integrally with the panel body 1a via the thin hinge 6. In this case, since the thin hinge 6 is weak in strength, it is reinforced by another iron hinge 6'to prevent it from being torn off when the airbag 2a is inflated and deployed.

[0017]

[Effect of the device]

 As described above, according to the present invention, an instrument panel having a panel body, a pad arranged on the panel body, and a skin formed on the surface of the pad, which is integrally formed and has an air bag device built therein. At the position where the above-mentioned airbag device of the panel body faces, an airbag pop-out opening is formed so that the airbag that inflates and deploys when the airbag device is activated can be popped out, and a hinge is provided on one side of this opening. A lid covering the opening is attached via a pad so as to be openable and closable, and the lid, which protrudes so as to bite into the pad and opposes when the lid is opened, at the edges of the other three sides except the one side to which the hinge is attached. Also, the protruding part of the cutter that ruptures the outer skin improves the appearance quality of the instrument panel and also prevents clothing from scratching. It does not give an uncomfortable feeling to the passenger without, moreover effect is obtained that is simple and inexpensive structure.
