Description

[Technical Field]

[0001] The present disclosure relates to an interior component and a method for manufacturing the interior component. [Background technology]

[0002] Conventionally, interior trim members having stitching have been known (see, for example, Patent Document 1). The interior trim member of Patent Document 1 has an edge of the skin folded inward, and the folded portion is sewn into a three-dimensional shape with double stitching. Such stitching is mainly used as an interior trim member for automobiles to create a high-quality feel for the interior of the automobile.

[0003] [Patent Document 1] International Publication No. 2006 / 028206 Summary of the Invention [Problem to be solved by the invention]

[0004] In recent years, such stitches have come to be used not only to fold back the edges of the skin, but also simply as decorations for sewing the design surface of the skin. When using stitches as decorations in this way, it is necessary to affix them to the base material while controlling the position of the stitches.

[0005] An object of the present disclosure is to provide an interior trim member capable of regulating the position of stitches, and a method for manufacturing this interior trim member. [Means for solving the problem]

[0006] The interior member according to the present disclosure comprises a base material and a skin. The skin has a first surface forming a design surface and a second surface opposite the first surface, and the second surface is attached to at least one surface of the base material. The skin has stitches formed by passing a thread from the first surface to the second surface, and recesses formed by the stitches on the second surface. The base material has a protrusion on one surface that protrudes toward the recesses.

[0007] In addition, the manufacturing method of an interior member according to the present disclosure includes a step of setting a substrate so that one surface is the outer surface, and a step of attaching a skin to one surface of the substrate so that a concave portion of the skin matches a convex portion of the substrate.

[0008] According to this manufacturing method for an interior member, the skin is attached so that the recesses formed by the stitches match the protrusions on the base material. This causes the stitches formed on the first surface of the skin to follow the protrusions on the base material. As a result, the position of the stitches is regulated in this interior member. [Effects of the Invention]

[0009] According to the present disclosure, it is possible to provide an interior member capable of regulating the position of stitches, and a method for manufacturing this interior member. [Brief explanation of the drawings]

[0010] [Figure 1] 1 is a diagram showing an interior member according to an embodiment of the present disclosure attached to a vehicle; [Figure 2] FIG. 2 is a front view of the interior member of the present disclosure removed from the instrument panel. [Figure 3] 2. FIG. 3 is a cross-sectional view taken along the line AA in FIG. [Figure 4] 5A to 5C are diagrams illustrating a method for manufacturing an interior member according to an embodiment of the present disclosure. DETAILED DESCRIPTION OF THE INVENTION

[0011] An embodiment of the present disclosure will be described below with reference to the drawings. In FIGS. 1 and 2, the upper side of an automobile is indicated by U. As shown in FIG. 1, an interior member 1 of this embodiment is a member that is attached to, for example, an automobile instrument panel 2. The instrument panel 2 includes a first interior member 1a having a single stitch S1 on its upper portion and a second interior member 1b having a single stitch S2 on its lower portion. For example, when the first interior member 1a and the second interior member 1b are attached to the instrument panel 2, the single stitch S1 and the single stitch S2 are formed parallel to each other, creating the appearance of a double stitch. When decorative single stitches S1 and S2 are used in the interior member 1, it is preferable to precisely form the single stitches S1 and S2 at predetermined positions (predetermined positions) to create a premium feel for the automobile interior.

[0012] Fig. 2 is a front view of the first interior trim member 1a. As shown in Fig. 2, the interior trim member 1a has a single stitch S1 formed near the upper end 4 of the design surface of the interior trim member 1a, the single stitch S1 being restricted to a predetermined position. In this embodiment, the single stitch S1 is formed at a position where the distance D from the upper end 4 to the single stitch S1 is within a predetermined range over the entire length of the single stitch S1. It is preferable that such a single stitch S1 be formed without deviating from the predetermined position on the design surface.

[0013] As shown in FIG. 3, the interior member 1 has a base material 6 and a skin 8. The base material 6 has hooks and the like for attachment to the instrument panel 2, and is a base member for supporting the skin 8. In this embodiment, the base material 6 is formed by injection molding a resin material such as PP (polypropylene). However, the base material 6 may also be formed from metal. The base material 6 has a surface 10 (an example of one surface) on the side where the skin 8 is attached, and a back surface 12 on the side where the instrument panel 2 is attached.

[0014] As shown enlarged in Fig. 3, the base material 6 has a protrusion 14. In this embodiment, the protrusion 14 extends in a straight line from one end 16 to the other end 18 (see Fig. 2) of the surface 10 of the base material 6. In other words, the protrusion 14 extends along the single stitch S1 that appears on the design surface.

[0015] As shown in FIG. 3 , the skin 8 is attached to the base material 6 and forms the design surface of the interior member 1. The skin 8 has a first surface 22 that forms the design surface, a second surface 24 opposite the first surface 22, a first layer 26 that forms the first surface 22, and a second layer 28 that forms the second surface 24. In this embodiment, the first layer 26 is formed of a material such as leather, synthetic leather, or woven fabric. The second layer 28 is formed of a foamed resin, for example. In this embodiment, the second layer 28 further has a laminate layer (not shown) formed of a thermoplastic resin on the surface facing the first layer 26. The first layer 26 and the second layer 28 are welded together by melting the laminate layer. However, the first layer 26 and the second layer 28 may be bonded together by other methods, such as by using an adhesive.

[0016] As shown enlarged in Figure 3, the single stitch S1 is formed by a thread penetrating from the first surface 22 to the second surface 24. The single stitch S1 is formed by penetrating the first layer 26 and the second layer 28 after the first layer 26 and the second layer 28 are bonded together. As a result, the thread of the single stitch S1 that has penetrated to the second surface 24 pulls up the foamed resin of the second layer 28, causing a depression in the second layer 28. This forms a depression 30 on the second surface 24 of the skin 8.

[0017] An adhesive is applied to the second surface 24 of the skin 8, and the second surface 24 of the skin 8 is adhered to the surface 10 of the base material 6, thereby attaching the skin 8 to the base material 6. When the skin 8 is attached to the base material 6, at least a portion of the protrusions 14 is housed in the recesses 30.

[0018] Next, each step of the manufacturing method of the interior member 1 will be described with reference to FIG.

[0019] As shown in Figure 4(a), the substrate 6 is set so that the surface 10 of the substrate 6 faces up. In this embodiment, the substrate 6 is set so that the surface 10 of the substrate 6 faces up. Next, the skin 8, with the adhesive applied to the second surface 24, is set on the front side of the substrate 6.

[0020] Next, as shown in FIG. 4(b), the concave portions 30 of the skin 8 are aligned with the convex portions 14 of the base material 6, and the skin 8 is attached to the base material 6 so that the convex portions 14 are housed in the concave portions 30 over the entire length of the convex portions 14. In other words, the concave portions 30 are attached first along the convex portions 14. This restricts the single stitch S1 to match the position of the convex portions 14. As shown by the dashed line in FIG. 4(b), with the single stitch S1 thus restricted to match the position of the convex portions 14, the parts of the skin 8 other than the concave portions 30 are attached to the surface 10 of the base material 6 (see the arrow in FIG. 4(b)).

[0021] Thereafter, as indicated by the dashed lines and arrows in FIG. 4(c), the skin 8 is folded back from the front surface 10 to the back surface 12 along the edge of the front surface 10 of the base material 6 and attached, thereby forming the interior member 1.

[0022] In the interior material 1 manufactured in this manner, the position of the single stitch S1 on the skin 8 is regulated to match the position of the convex portion 14 on the base material 6. This makes it possible to prevent the position of the single stitch S1 from deviating from the convex portion 14 on the base material 6 when the skin 8 is attached to the base material 6. As a result, it is possible to prevent the single stitch S1 from deviating from its predetermined position and becoming distorted when the skin 8 is attached to the base material 6. In this embodiment, as shown in FIG. 2, the single stitch S1 does not distort vertically, and is formed at a uniform distance D from the upper end 4 of the interior material 1. This improves the appearance of the design surface and makes it easier to create a sense of quality.

[0023] Furthermore, because the recess 30 accommodates the protrusion 14, the gap behind the single stitch S1 (the gap between the recess 30 and the protrusion 14) is small or absent, which makes it difficult for wrinkles to form in the skin 8 due to this gap during the manufacturing process of the interior material 1. This further improves the appearance of the design surface.

[0024] As described above, according to the present disclosure, an interior trim member 1 capable of regulating the position of the single stitch S1 and a method for manufacturing this interior trim member 1 can be provided.

[0025] <Other embodiments> Although the embodiments of the present disclosure have been described above, the present disclosure is not limited to the above embodiments, and various modifications are possible without departing from the spirit of the invention.

[0026] (a) In the above embodiment, the interior member 1 attached to the instrument panel 2 has been described as an example, but the present disclosure is not limited to this. The interior member 1 may be an interior member for any part of an automobile, such as an armrest or door trim, as long as it is an interior member used in an automobile interior. Furthermore, the interior member 1 is not limited to automobiles, and may also be an interior member 1 for trains, airplanes, etc.

[0027] (b) In the above embodiment, the protrusions 14 extend in a straight line from one end 16 to the other end 18 of the surface 10 of the base material 6, but the present disclosure is not limited to this. For example, the protrusions 14 may be provided in a dashed line from one end 16 to the other end 18 of the surface 10 of the base material 6. Furthermore, the protrusions 14 may be provided on a portion of the surface 10 of the base material 6. Furthermore, the protrusions 14 do not necessarily have to be in a straight line, and may be curved to match the design of the decorative stitches to be applied to the design surface.

[0028] (c) In the above embodiment, a single stitch S1 is used as an example, but the stitch may be a double stitch or a triple stitch. [Explanation of symbols]
