Description

[Detailed Description of the Invention] (a) Purpose of the Invention (Technical Field of the Invention) The present invention relates to a trim cover for a vehicle seat that has an uneven pattern formed on its surface.

(Technical background of the invention) The surface of vehicle seats is decorated with various patterns that give it a sense of beauty.

In recent years, trim covers having a wadding layer of foamed urethane or the like have come to be used as the skin material of seats, and three-dimensional uneven patterns have been formed on the skin.

Products with this uneven pattern are particularly preferred by users because they have a novel aesthetic feel compared to those with a flat pattern that is just a combination of color and pattern.

In addition, as for the form of the concavo-convex pattern, a pattern in which several parallel grooves are formed in the portion corresponding to the seating portion of the seat is generally used.

In this way, the uneven pattern produces a novel aesthetic effect due to its three-dimensional effect, but in reality, there is a limit to the thickness of the wading layer due to its functional conditions, and there are problems with seating comfort and the occurrence of wrinkles. Because of this, it was not possible to set very deep unevenness, and the depth was 10 mm.
Before and after.

Therefore, the current uneven pattern lacks a three-dimensional effect;
The unique aesthetic effect of the pattern is not fully demonstrated.

(Prior art and its problems) As a means of emphasizing the three-dimensional effect of the uneven pattern, as shown in Japanese Utility Model Publication No. 56-54880, the bottom surface of the grooves is colored in a complementary color to the color of the convex parts of the skin, and a plurality of grooves are colored. There is one that attempts to emphasize the three-dimensional effect of the groove pattern, which is arranged in parallel.

However, the effect of this complementary color is that the contrast between the two colors becomes stronger. In other words, when two complementary colors are placed side by side, the saturation of each color becomes higher than when each color stands alone, resulting in brighter colors. However, it does not primarily produce a three-dimensional effect.

Furthermore, this contrasting phenomenon using complementary colors does not occur when two colors are arranged in a thin striped pattern, and the difference between the two colors appears to be closer than it actually is. This is called color assimilation (or fusion), and this phenomenon is more likely to occur when colors are similar in hue, brightness, saturation, and color area.

Therefore, the method disclosed in the above-mentioned Japanese Utility Model Publication No. 56-54880 has a poor three-dimensional effect, and when used in a design in which several parallel grooves are formed on the seating part, which is commonly used, Not only is the three-dimensional effect further reduced, but if the three-dimensional effect is to be increased even a little, primary colors must be used for the tint, resulting in a product with extremely low quality and low commercial value.

In addition, there was a problem that the color scheme in the design was limited, making it unsuitable for practical use.

(Technical Problem of the Invention) A technical problem of the invention is to provide a trim cover for a vehicle seat in which an uneven pattern is formed on the surface, without changing the depth of the uneven pattern formed in the wading. The purpose is to emphasize the feeling.

(b) Structure of the invention (technical means of the invention) In order to solve this technical problem, the technical means of the invention is to provide a trim cover for a vehicle seat with an uneven pattern on its surface. It has a structure in which a fine uneven pattern is formed on the skin that forms the bottom of the recess.

(Effect of technical means) According to this technical means, a fine uneven pattern is formed on the skin that forms the bottom of the recessed part of the uneven pattern.
The bottom of the recess becomes dark due to the diffused reflection of light, and the perspective effect of the shadow emphasizes the three-dimensional effect of the uneven pattern.

(c) Effect of the invention As described above, according to the present invention, the three-dimensional effect of the uneven pattern is emphasized by the shading of the fine uneven pattern formed on the bottom of the recess, which makes it easier to set the depth of the uneven pattern. The unique aesthetic effect of the textured pattern can be fully demonstrated even with the conventional depth that satisfies various conditions such as seating comfort and wrinkle generation, creating a vehicle seat with high commercial value that has a novel and luxurious beauty. Can be provided.

Furthermore, since the color scheme of the uneven pattern is not limited, it is possible to provide sheets with colors that meet the various needs of users.

(d) Example of the invention Next, how the trim cover of the vehicle seat of the invention is actually implemented will be explained using an example.

Fig. 1 is a perspective view of a vehicle seat, and Fig. 2 is an enlarged perspective view of the main parts of the trim cover of the present invention. Seat A has an uneven pattern B consisting of a plurality of parallel grooves 1 in the central seating area. The trim cover 2 is also covered.

The trim cover 2 has a wading 4 made of polyurethane foam or other soft foam sheet layered on the back side of an outer skin 3 made of polyvinyl chloride or other synthetic resin sheet, or leather, etc., and a wadding 4 made of polyurethane foam or other soft foam sheet is layered on the back side of the wading 4. It is constructed by layering wading covers 5.

The uneven pattern B of the trim cover 2 is wading 4.
A plurality of parallel grooves are formed by router processing etc. to give an uneven shape, and then the skin 3 is applied to this uneven shape, and the wading 4 and the skin 3 are welded by high frequency welding at the bottom of the recess of the uneven shape. It is formed by sticking together.

A fine uneven pattern 6 by welding is formed on the surface of the skin 3 forming the bottom b of the concave portion of the uneven pattern B thus formed (FIG. 2).

From this, the bottom b of the concave portion of the concave-convex pattern B loses its luster and becomes dark due to the diffuse reflection of light by the fine concave-convex pattern 6, and due to the perspective effect of the shadow, it appears to be further retreating from the actual depression depth.

Therefore, the three-dimensional effect of the uneven pattern is emphasized.

FIG. 3 is an enlarged perspective view of a main part showing a second embodiment of the trim cover of the present invention. A fine concavo-convex pattern b in the form of a squeeze pattern is adhered to the surface of the skin 3.

Therefore, the bottom b of the concave portion of the concavo-convex pattern B loses its luster and becomes dark due to the diffuse reflection of light by the fine concave-convex pattern 6, and due to the perspective effect of the shadow, it appears to be further retreating from the actual depression depth.

Therefore, the three-dimensional effect of the uneven pattern is emphasized.

Incidentally, the means shown in this second embodiment is effective when the skin material is leather.

Further, in each of the above embodiments, the case where the uneven pattern B is a groove pattern consisting of several parallel grooves has been explained, but the form of the uneven pattern B is a lattice pattern, a tight instep pattern,
It may be a polka dot pattern or other three-dimensional pattern, and the fine uneven pattern 6 formed on the bottom b of the recessed part of the uneven pattern B is not limited to the groove pattern consisting of several parallel grooves as shown in the figure. Any three-dimensional pattern that can be formed may be used.
