Description

[Detailed Description of the Invention] This invention relates to automobile interior parts such as sun visors or door trims that display warning messages such as ``Caution for Driving'' and ``Caution for Maintenance.''

In recent years, it has become a legal requirement to display warning messages such as "Driving Precautions" and "Maintenance Precautions" on automobile interior parts such as door trims to alert drivers. The warning message must be placed in a place where the driver can clearly see it when sitting in the driver's seat.

In order to improve the external appearance of interior products such as sun visors and door trims to give a sense of luxury, the surface of the skin material, which is usually made of vinyl chloride, is coated with fine irregularities (hereinafter referred to as "grains"). is formed.

In addition, as shown in Figure 1, the conventional warning message of this type is a caution message such as ``Caution when driving on transparent vinyl chloride film B (hereinafter simply referred to as vinyl chloride film)'', which has a smooth surface.
was printed to give the appearance of display label a, and the outer periphery of label a was welded and attached to the skin material forming the sun visor or door trim.

However, when the warning message C is attached to the above-mentioned interior parts by such welding, the following problems arise.

(1) The PVC film on which the above warning message is printed needs to be rigid in order to print properly on it, so semi-rigid vinyl chloride is generally used. The skin material that forms the interior is soft, and typically a soft vinyl chloride sheet is used to give it a luxurious feel.

Incidentally, the plasticizer contained in the PVC film is about 20 parts, and the plasticizer contained in the skin material is about 40 parts, and because one is semi-hard and the other is soft, the heat shrinkage rates of the two are different. It is something.

After the PVC film as described above is printed, it is pasted onto the skin material by welding as described above, but as a result, there is no interference between the PVC film and the skin material. The air is completely sealed.

In addition, these sun visors, door trims, etc. are installed inside the vehicle interior, and as this vehicle interior is directly exposed to changes in the temperature of the outside air, there is a large difference in temperature, and especially in the summer, the interior of the vehicle can reach considerable high temperatures ( The ambient temperature is approximately 82°C, and the temperature in areas exposed to direct sunlight is approximately 104°C), especially for sun visors, sunshades are areas exposed to direct sunlight during use, and doors). The upper part is most susceptible to temperature changes, and therefore, when printing on such a part, it must be designed to withstand particularly harsh usage conditions.

However, when a PVC film is pasted on a surface material made of vinyl chloride as described above, the air interposed between the image materials expands due to the high temperature inside the vehicle, and as a result, the printed PVC film expands due to the high temperature inside the vehicle interior. There was a problem in that the film also expanded, making the printed surface difficult to see.

(2) If used for many years under the harsh conditions described above, the thermal contraction rate of the painting material will no longer be able to cope with the temperature, resulting in permanent deformation of the painting material. When the polyvinyl chloride film is stretched out and becomes tangled, wrinkles and slack occur in the vinyl chloride film, which not only makes the printed surface even more difficult to see, but in the worst case scenario, the vinyl chloride film peels off from the surface material.

(3) The PVC film with the printed surface is semi-hard and the skin material is soft, so if these are combined and pasted together, it will feel stiff and will spoil the sense of luxury. When attaching the PVC film to the skin material, the PVC film is manually positioned at a predetermined position on the skin material and then welded. In addition to being troublesome, if the positioning is not accurate, the PVC film may become loose or wrinkled, making it difficult to see the printed display surface, and making it impossible to provide automotive interior parts of uniform quality. Problems were pointed out.

(4) Since the display label a with the warning text is made of a smooth vinyl chloride film, when light hits it, the light is reflected.

As a result, the most important warning text is reflected by this reflected light, making it difficult to read, and there has been a problem in the past that drivers have often overlooked this warning text15.

(5) According to the method of installation as described above, steps such as cutting the PVC film, printing the warning C on the PVC film, and then attaching it to the sun visor or door trim by welding are necessary. Therefore, there is a problem in that it takes a lot of man-hours and effort, and inevitably leads to high costs.

(6) Since the outer periphery of the 0 display label a is welded, a welding line remains after installation, which causes a problem in that the appearance after installation is poor.

This invention was made in view of this technical background, and this invention is a skin material made of vinyl chloride that is textured and forms a sun visor or door trim. The purpose of the sunshade is to easily solve the above problems by printing a "warning message" directly on the top of the door trim when the sunshade is exposed to direct sunlight during use or on the door trim. It is.

Hereinafter, embodiments of this invention will be described in detail based on the drawings.

1 shows a sun visor in automotive interior parts,
The skin material of this sun visor 10 is made of vinyl chloride, and the skin material 3 is textured.
Further, on the surface of the skin material 30, a warning message 4 such as "Driving Precautions" is directly printed and displayed at a location where the sunshade receives direct sunlight during use.

Screen printing is a method of directly printing on the surface material, and in this screen printing, printing ink is rubbed against the surface of the rope, and the ink is removed from the image line and transferred to the surface to be printed. Silk screen printing (usually called silk printing) or stencil A screen and an electrode are placed facing each other with an appropriate distance between them, the surface to be printed is placed between them, and a DC voltage is applied between the screen and the electrode to form a powder. One example is electrostatic screen printing (usually referred to as electrostatic printing), which prints by dropping ink.

The part shown in FIG. 3 shows the door trim. In this door trim 2, there is also a "warning message" 4 on the surface of the skin material 39 which is textured like the sun visor. is displayed directly by screen printing.

This invention forms a sun visor or door trim as described above, and is a skin material made of vinyl chloride that is textured.In addition, in the above-mentioned sun visor, the sunshade is placed in a place exposed to direct sunlight during use, or in the door trim. Since the "warning message" is printed directly on the top of the warning, it has the following features.

(1) Since the "warning text" is printed directly on the textured vinyl chloride surface/skin material, there is no difference in heat shrinkage between the surface material and the printed surface as in the past. There is absolutely no room for air to exist between the two.

Therefore, even if the inside of the vehicle gets quite hot in the summer, it is especially likely to become hot and there are large temperature differences, and in the case of foldable sun visors, sunshades are placed in areas that are exposed to direct sunlight during use, or on door trims. Since there is no risk of loosening or wrinkles on the printed surface at the top, there is no risk that the printed display surface will become difficult to see, and there is also no risk that only the printed display surface will peel off from the cover material as in the past. .

(2) Since the display is printed directly on the skin material, there are no separate parts on the skin material, so the feel of the skin material is
You can make the most of it without sacrificing the sense of luxury.
Moreover, since no special positioning work is required when printing and displaying, there is no risk of slack or wrinkles occurring on the print display surface, and a uniform interior product can be provided.

(3) Since it is directly printed on the textured surface material, the "warning message" on the surface material causes diffused reflection due to the unevenness of the texture of the surface material.

Therefore, since there is no reflection of light, the warning message itself is not reflected, making it very easy to see and preventing unexpected troubles.

(4) Since it is not necessary to cut the PVC film, print on it, and then attach it by welding, this type of warning message can be displayed on the skin material at low cost.

(5) Direct printing by screen printing makes it possible to print directly, easily and accurately onto the skin material, and also has the effect of further improving the external appearance since no processing marks are left.
