Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an instrument panel for automobile interior parts.

(Prior Art) Conventionally, an instrument panel of an automobile (hereinafter abbreviated as an instrument panel) is separately formed by a vacuum forming method, a slash forming method, or the like, the obtained skin is set in a foaming mold, and then an insert is inserted. It is obtained by injecting a urethane foam foaming stock solution and foaming. It is also obtained by an in-mold coating method in which a skin forming material is directly applied to a foaming mold to form a skin, and then an insert is inserted, and a urethane foam foaming undiluted solution is injected and foaming is performed.

Recently, a softer feeling than ever has been demanded, and in order to meet this demand, softening of one or both of the polyurethane foam and the epidermis has been studied.

However, recent instrument panels have become complicated in design, and the tip of the meter hood is often sharp. Although a molded product of a thermoplastic resin is used for the insert, in the case of a meter hood having a complicated and sharp shape, it is technically difficult to make the tip of the insert reach the tip of the skin. If the insert does not reach the tip of the meter hood, that portion is softer than other portions and gives a feeling of strangeness, and when the temperature inside the vehicle rises in the summer, the tip portion may be deformed such as hanging down.
Furthermore, when foaming urethane foam, the liquid in the urethane spreads in a narrow space in such a sharp area, so the air in the mold is trapped and remains as a large void (air retention). There is also.

(Problems to be solved by the invention) The purpose of the present invention is to increase the hardness of the tip of the meter hood,
It is to provide an instrument panel whose design shape is clear.

Another object of the present invention is to provide an instrument panel that does not have the above-mentioned discomfort or void (air retention) at the tip of the meter hood and does not deform even at high temperatures in summer.

(Means for Solving the Problems) The present invention is an instrument panel of an automobile made of a polyurethane foam having an outer skin and an inner insert, wherein a soft outer skin made of a soft material is used as the outer skin, and the inner insert is provided at the tip of the meter hood. The present invention relates to an instrument panel characterized in that a long glass fiber mat is inserted and reinforced so as to wind the inner insert above and / or below the inner insert or around the inner insert.

Next, the present invention will be described with reference to the drawings. FIG. 1 is a schematic view of the instrument panel 1 as seen from above, and 2 is a meter hood portion. In the instrument panel of the present invention, the skin obtained by any conventionally known method is set in a foaming type, and then the glass long fiber mat 5 is put in a portion of the skin corresponding to the tip portion 3 of the meter hood, and from there After inserting the insert, it is obtained by injecting a urethane foam foaming stock solution and foaming. As the skin material, a conventionally known skin material can be used. For example, polyvinyl chloride (PV
C), polyurethane, acrylonitrile-butadiene-
It is possible to use a synthetic resin such as styrene resin (ABS), polyethylene, polypropylene, polyester, or nylon, which is molded by a slush molding method, a vacuum molding method, an in-mold coating method, or the like. The thickness of the skin can be about 0.2 to 2 mm by slush molding and vacuum forming, and about 0.01 to 3 mm by the in-mold coating method, and any of them can be used as the skin material of the present invention. As the long glass fiber, known ones can be used. Among them, a long glass fiber mat formed by stacking continuous long glass fibers spirally into one or more layers and forming a mat with a binder (for example, Asahi Fiber strand glass, continuous strand mat, abbreviated as CSM, etc.) can be particularly preferably used.

In the present invention, the long glass fiber mat may be placed on either the upper side or the lower side of the insert portion located at the tip of the meter hood, or may be placed on both sides. It is preferable to put the long glass fiber mat 5 around the insert 4 as shown in the figure. 6 is a urethane foam, 7 is a skin, and 8 is a foam type. or,
Even in the case of any of the above methods, when the glass long fiber mat is attached to the insert with a double-sided tape, an adhesive or the like, the displacement of the glass long fiber mat is prevented, and the glass long fiber does not stick to the epidermis. preferable. FIG. 3 shows a case where a long glass fiber mat is arranged around the insert and is adhered thereto. Bonding of the long glass fiber mat and the insert may be complete or partial. After the long glass fiber mats and inserts have been set, the urethane foam foaming stock solution is injected and foamed according to a known method to obtain the desired reinforced instrument panel.

In the present invention, a long glass fiber mat is selected in order to prevent the above voids and to give hardness to a portion where the insert cannot reach. The long glass fiber mat increases the hardness of the foam in the part that the insert does not reach, and the air entrapped during urethane foam molding also has air mass dispersed when passing through the long glass fiber mat during foaming. It exerts the effect that it does not become a large void.

(Effect of the invention) According to the present invention, the hardness of the tip of the meter hood is increased,
It is possible to manufacture an instrument panel with a clear design shape, this instrument panel has no discomfort or void (air retention) that the hardness differs depending on the part, and it is excellent that it does not deform even at high temperatures in summer It is a thing.
