A method for manufacturing the instrument panel 1 will be described. First, the skin 13 and the cushion layer 12 are laminated into a sheet by extrusion lamination. Next, core material 1
1 is extruded into a sheet, and the core material 11 is extruded.
The core material 11 and the sheet-like skin 13 and the cushion layer 1 are bonded so that the cushion layer 12 is adhered to the core material 11.
2 is laminated. Next, these sheet-shaped core materials 1
1. A predetermined shape is imparted by vacuum forming a sheet-like laminate including the cushion layer 12 and the skin 13. Thereafter, the outlets 10a through 10 are trimmed.
The panel body 10 is completed by forming the holes 10d and the receiving holes 10d and 10e. This panel body 10
Then, a separately formed rim 20, differential nozzle 30, ventilation duct 40, audio receiver 50, and meter receiver 60 are attached by, for example, vibration welding or the like.

The instrument panel 1 includes a core 1
Since 1 is vacuum formed and made thin, it can be made lightweight. For example, while the conventional instrument panel using an injection-molded core material (with a differential nozzle or the like attached) is 3.5 kg, the applied product of the present invention can be reduced to 3.2 kg. did it. The peripheral edge of the panel body 10 is reinforced by the hook 32 of the rim 20 and the differential nozzle 30, and the outlets 10a to 10c and the accommodation holes 10d and 10e are provided with the differential nozzle 30, the ventilation duct 40, the audio receiver 50, Meter receiver 6
It is reinforced with 0. Therefore, the required strength can be sufficiently satisfied.

The present invention is applicable not only to instrument panels but also to other vehicle interiors such as door trims and consoles. When applied to door trim, for example,
The impact absorbing material at the time of side collision is made by foam molding, blow molding, injection molding or the like so as to be stronger than the trim main body (interior main body), and this shock absorbing material is fixed to the trim main body and also serves as a reinforcing member. . Further, a clip seat for a clip for connection to the door body is formed by injection molding, and this is fixed to the trim body as a reinforcing member. When the present invention is applied to a console, for example, a mounting portion for a floor at a lower end, a mounting bracket for an AT shift display panel, and the like are formed by injection molding, and this is fixed to a console body (interior body) as a reinforcing member. In the vehicle interior of the present invention, the core material may be vacuum-formed separately from the cushion layer and the skin, and then bonded together.

[0017]

As described above, in the first invention,
The vehicle interior can be reduced in weight, the material cost can be reduced, and the strength can be ensured by the reinforcing member. Second
According to the invention, the outer peripheral edge of the interior can be reinforced. According to the third aspect, the periphery of the hole formed in the interior can be reinforced. In the fourth invention, the air passage can be formed by the reinforcing member and the interior main body. In the fifth aspect, the core material, the cushion layer, and the skin can be vacuum-formed together, so that the molding cost can be reduced. Moreover, the vehicle interior can be reduced in weight, and the strength can be ensured by the reinforcing member.
