Definitions
- the present invention relates to an airbag storage cover, and more particularly to an airbag storage cover having a mark.
- FIG. 2 is a schematic partial sectional front view showing a state in which the air bag storing power bar is attached to the air bag
- FIG. 3 is a diagram showing the air bag storing power bar.
- 1 is an airbag storage cover
- 2 is an airknob
- 3 is an inflator
- 4 is a ring retainer
- 5 is a lid.
- One retainer, 6 is a plate
- 7 is a rivet.
- the cover 1 for storing an air bag has a shallow box shape having a main plate 100 and a side plate 101 rising from a side of the main plate 100.
- the cover 1 is mainly composed of a thermoplastic resin, and includes a skin layer 1A, and a core layer 1B made of a resin having a higher hardness than the skin layer 1A.
- the core layer 1B is provided with a tear line 1C to easily cleave the cover 1 when the air bag operation is started. This
- the tear line 1C is formed of, for example, a notch-like thin shape, a perforated slit shape, or the like.
- Such an air bag storage force bar is generally manufactured by an injection molding method.
- a core layer is molded in advance, the molded article is mounted on a mold left in the space of the skin layer, and the skin layer is made of a thermoplastic polymer.
- a so-called insert injection method of injection molding a skin material is exemplified.
- the core layer is formed, then the cavity mold is separated, and the skin layer space is continuously formed without removing the core molded product from the mold.
- the so-called two-color molding (double injection) method of injecting and molding a skin material with a new cavity mold is applied.
- the above-mentioned tear line is formed on the core layer 1B.
- Such an air bag storage cover 1 is provided with a mark such as a symbol or a letter on the surface of its skin layer 1A for the purpose of product identification or the like.
- this mark is formed by printing with paint.
- As another mark forming method there is a method of forming an uneven pattern on a part of the skin layer when forming the skin layer 1A. -In the case of the conventional mark forming method using paint printing, the paint may come off and the mark may not be identified. Moreover, simply printing on the skin layer cannot provide a high-quality mark. In addition, After molding, the need for by that printing process to paint, production efficiency is not evil c
- the marks are given irregularities, giving a sense of luxury. You can be a mark. Even in this case, the mark is formed from the same resin as the skin layer, so the texture and color of the mark area are the surrounding skin. It is the same as the layer. For this reason, their aesthetics and luxuriousness are not enough. Moreover, such marks formed by the unevenness of the resin of the same material may be difficult to identify depending on the lighting conditions and may not be easily confirmed.
- the present invention solves the above-mentioned conventional problems, and is an air bag storage cover having a mark that is rich in aesthetics and luxury, and that is easy to identify and that is not likely to come off.
- An object of the present invention is to provide a cover for storing an air bag that can be manufactured efficiently.
- the cover for airbag storage of the present invention is characterized in that the mark exposed on the front side is formed by multicolor molding or insert molding.
- the mark exposed on the skin layer can be formed with a resin different from the resin of the skin layer.
- the mark is formed by insert molding.
- a mark that appears on the skin layer can be formed with a metal other than the resin, another inorganic material, or the like. Shika also has no risk of these marks coming off.
- the mark of the cover for storing the air bag according to the present invention has a different texture, color tone, and gloss from the skin layer, is aesthetically pleasing, and has a high-grade feel. It is also excellent.
- FIG. 1a and FIG. 1b are cross-sectional views each showing a mark portion of an air-knock storage canopy according to an embodiment of the present invention.
- Fig. 2 is a schematic partial cross-sectional front view showing a state in which the airbag storage cover is attached to the bag, and
- Fig. 3 is a rear view of the airbag storage cover. .
- the mark 1OA that appears on the skin layer 1A is formed by multicolor molding. That is, the cover 1 for storing the air bag of the present embodiment is obtained by first injection molding a core layer forming material in a mold. Then, a core layer 1B is formed, and then, the cavity mold is separated, and the core molded product is continuously removed without removing the core molded product from the mold. The mark forming material is injection-molded by covering another mold having the mold, then the mold is separated, and the molded product is continuously removed without being removed from the mold. Then, it is manufactured by so-called three-color molding in which a further cavity type having a skin layer space is covered and injection molding of a skin layer forming material is performed.
- the resin used as the mark forming material there is no particular limitation on the resin used as the mark forming material. If necessary, the resin forming the skin layer 1A and the material may be used. Resins with different gloss, color tone, etc. can be used.
- the mark 10B exposed on the skin layer 1A is formed by insert molding. That is, in the air bag storing cover 1 of the present embodiment, the mark 10B is previously arranged at a predetermined position in the mold, and the air bag storing cover 1 is formed according to the two-color molding method described above. It is manufactured by injection molding the core layer 'fB and the skin layer 1A.
- the material of the mark 10B is an inorganic material such as metal, glass, ceramic, or the like. Etc. can be used. In addition, any resin that can withstand the injection molding temperature can be used.
- the resin material of the skin layer and the core layer is used.
- the resin material of the skin layer and the core layer is used.
- the mark may be formed at any position.
- the area of the portion buried in the skin layer 1A (cross-sectional area of the plane parallel to the surface of the skin layer 1A), as shown in Figs. Is preferably designed to be larger than the area of the surface exposed on the skin layer 1A.
- the airbag has a mark that is rich in aesthetic appearance, luxury, easy to identify, and excellent in durability.
- a power bar is provided for storing the bag.
- the cover for storing the air bag of the present invention can be easily and accurately formed by a rational molding method, with little occurrence of defective products, and reliably and efficiently at a high yield. It can be manufactured, and the cost of the product can be significantly reduced.
