する等の問題点があり、良質の製品が得られなかった。However, in the manufacturing process of such an instrument panel integrated with an air duct, the molding process of the outer skin 11, the molding process of the core material 12, and the cushion layer 13 formed by injection foaming.
Of the air duct 15, the step of connecting the air duct 15 and the instrument pad 14 and the like are required, and many steps are required to complete the process. Is bad. Further, a cushion layer 13 formed by foaming between the skin 11 and the core 12, and the skin 11 or the core 12
However, there was a problem that the adhesiveness with the product was poor, wrinkles were formed on the surface skin 11 during the foam molding, and the foaming agent leaked out when the foaming agent was injected.

したものである。The present invention has been made in view of such conventional problems, and an air duct and a skin located around the air duct are simultaneously formed by blow molding, and further formed between the air duct and the skin. By filling the bag-shaped portion with a granular filler, the manufacturing process can be simplified and a high-quality instrument panel can be produced.
以下に本発明の第１図及び第２図に示す実施例に基い
て詳細に説明する。The present invention will be described in detail below with reference to the embodiments shown in FIGS. 1 and 2.

粒子３が衝撃吸収のクッション機能を有するインストル
メントパネル４が構成されるものである。Reference numeral 1 denotes an air duct blow-molded with a hard resin, and at the same time as blow-molding the air duct, a skin 2 located outside the air duct is blow-molded with a soft resin. During the simultaneous blow molding of the air duct 1 and the skin 2, air is supplied between the air duct 1 and the skin 2 to form a hollow portion so that the air duct 1 and the skin 2 are not adhered to each other. Next, by filling foamed resin particles 3 such as foamed beads or balloons between the hollow portion, that is, the air duct 1 and the skin 2, the foamed resin particles 3 constitute an instrument panel 4 having a cushioning function of absorbing shock. It is something.
このように本実施例においては、エアダクト１と表皮
２とがブロー成形により同時形成されることから、従来

パネルを量産化することもできる効果がある。As described above, in this embodiment, since the air duct 1 and the skin 2 are simultaneously formed by blow molding, it is possible to omit the multistep process of individually molding the air duct and the skin as in the conventional case, and to improve the productivity. it can. Further, in the present embodiment, in the space formed between the air duct 1 and the skin 2,
Since it is filled with the foamed resin particles 3 and has a shock absorbing function, the conventional foam molding process can be omitted, and further, problems such as non-uniformity of impact material hardness due to leakage or non-uniform foaming of the foam material are caused. There is an effect that it is possible to eliminate the problem, and it is possible to mass-produce a high-quality product, that is, an instrument panel, in which a shock absorbing layer which is uniform over the whole is formed.
