[0005] Patent Document 1: Japanese Realization Publication No. Sho 60-18040 SUMMARY

[0006] A corner portion of a vehicle interior material, such as a corner portion of a door armrest, as shown in FIG. 1, is in a state in which a folded-back portion 222A of an end portion of an upper skin 22A, an unfolded portion 221A of the end portion of the upper skin 22A, a folded-back portion 232A of a terminal end of a lower skin 23A, and an unfolded portion 231A of the end portion of the lower skin 23A, which are sewn, overlap a total of four pieces. Therefore, as shown in FIG. 2, the overlapping portions sometimes become thick and bulge, thereby protruding. Figure 6 Figure 6

[0007] An object of the present application is to provide a vehicle interior structure in which a portion in which a folded-back portion of an end portion of an upper skin and a folded-back portion of a terminal end of a lower skin overlap does not bulge.

[0008] [MEANS FOR SOLVING THE PROBLEM]

[0009] In order to achieve the above object, the present application provides a vehicle interior structure in which an upper skin (for example, an upper skin 22 described later) and a lower skin (for example, a lower skin 23 described later) are stitched, at least one of the upper skin and the lower skin is provided with a decorative stitch (for example, a decorative stitch 25 described later), and an inner liner that becomes a vehicle interior material (for example, a core material 21 described later) is sewn and disposed, the decorative stitch is formed in a substantially L shape with a corner portion (for example, a corner portion 251 described later), and a recess (for example, a recess 212 described later) is formed in the interior material corresponding to the corner portion.

[0010] ​​Accordingly, the portion of the lower skin in which the end edge portion is folded back and overlapped can be accommodated in the recess. In particular, in the portion of the decorative stitch formed in an L shape having a corner portion, the portion of the lower skin in which the end edge portion is folded back and overlapped is thickened in an L shape, but this thickened portion of the lower skin can be accommodated in the recess. As a result, the thickened portion can be prevented from protruding upward and into the room, and the portion of the upper skin in which the end edge portion is folded back and overlapped can be prevented from protruding upward and bulging, and the occurrence of wrinkles can be suppressed by forming the lower skin and the upper skin in an L shape, so that the shape can be formed in which a good appearance can be ensured.

[0011] At this time, it is preferable that the aforementioned upper skin and the aforementioned lower skin constitute skins of a door armrest (for example, the armrest 10 described later). Accordingly, in the corner portion of the armrest in which the skins are likely to bulge and wrinkles are likely to occur, bulging and wrinkles of the skins can be prevented from occurring.

[0012] (EFFECTS OF THE INVENTION)

[0013] According to the present application, bulging of the portion in which the folded-back portion of the end portion of the upper skin overlaps the folded-back portion of the end portion of the lower skin can be prevented. BRIEF DESCRIPTION OF DRAWINGS

[0020] Hereinafter, an embodiment of the present application will be described in detail with reference to the drawings. Figure 2 is a perspective view illustrating a core material 21 of a door armrest 10 having a vehicle interior structure. Figure 3It is a cross-sectional perspective view showing a core material 21 of a door armrest 10 having a vehicle interior structure. Figure 4 1 is a cross-sectional view showing a main part of a door armrest 10 having a vehicle interior structure. Figure 5 It is an explanatory diagram showing the upper surface and the lower surface of a door armrest 10 having a vehicle interior structure.

[0021] Vehicle interior structures, such as Figure 1 As shown, the portion of the armrest 10 constituting the door trim 1 of the vehicle is as shown in FIG. Figure 4 As shown in FIG. 1 , the inner cover has a core material 21 as an interior material, an upper cover 22 , a lower cover 23 , sewing pins 24 , and decorative pins 25 .

[0022] Core material 21 is attached to door trim 1 via bosses (not shown) and is formed into the shape of armrest 10. Cushioning material 26 is disposed on the surface of core material 21, and an upper skin 22 and a lower skin 23 serving as an inner lining are disposed to cover cushioning material 26. Upper skin 22 and lower skin 23 are sewn together using sewing stitches 24 to form an inner lining.

[0023] Specifically, a corner portion 241 ( Figure 5 The edge of the upper epidermis 22 and the edge of the lower epidermis 23 are folded back. In this way, the upper epidermis 22 and the lower epidermis 23 in the state where the edge of each end is folded back are as shown in FIG. Figure 5 As shown, they are overlapped in the vertical direction. In this state, the folded-back end edges are sewn together by sewing pins 24.

[0024] Furthermore, on the upper surface 22, the decorative stitches 25 are provided by sewing along the sewing stitches 24. Specifically, Figure 4 As shown, a decorative stitch 25 for sewing the upper skin 22 and the cushioning material 26 is provided at the end portion on the indoor side which is bent by folding back the upper skin 22 .

[0025] The corner portion 211 of the core material 21 forming the outer shape of the handrail 10 (see Figure 3 、 Figure 4 The sewing stitches 24 and the decorative stitches 25 at the corresponding positions, i.e., the sewing stitches 24 and the decorative stitches 25 at the corners 211 of the core material 21, are provided with: the corners 101 of the armrest 10 of the door trim 1 are respectively formed into substantially L-shaped corner portions 241 (refer to Figure 5 ), and the corner portion 251 of the decorative stitch 25.

[0026] The corner portions 241 of the sewing pins 24 and the corner portions 251 of the decorative pins 25 are formed into substantially L shapes. Figure 4 As shown, the folded portion 222 of the upper epidermis 22, the unfolded portion 221 of the upper epidermis 22, the folded portion 232 of the lower epidermis 23, and the unfolded portion 231 of the lower epidermis 23 overlap, forming a total of four overlapping pieces. Figures 2-4 As shown, a recess 212 is formed in the portion of the core material 21 facing the portion where the four pieces are overlapped, that is, in the portion of the core material 21 corresponding to the corner 241 of the sewing stitch 24 and the corner 251 of the decorative stitch 25.

[0027] recess 212, such as Figures 2-4 As shown, it is formed into a substantially L-shape, and is formed so that the upper surface of the corner portion 211 of the core material 21 facing the corner portion 241 of the sewing stitch 24 and the corner portion 251 of the decorative stitch 25 extends from the position of the end edge 213 on the indoor side to the outside of the vehicle ( Figure 4 The left side of the figure) becomes gradually deeper. Figure 3 As shown in FIG. 1 and FIG. 2 , the recessed portion 212 is configured to gradually become shallower as it moves away from the portion along the upper surface of the core material 21 .

[0028] like Figure 4 As shown, the recessed portion 212 accommodates a portion 232 of the lower skin 23 where the two pieces overlap due to the folding back, and an unfolded portion 231. The folded back portion 222 of the upper skin 22 is sewn to the folded back portion 232 of the lower skin 23 using sewing stitches 24 while being accommodated in the recessed portion 212 and placed on the folded back portion 232 of the lower skin 23 and the inner-facing edge 213 of the upper surface of the core material 21.

[0029] According to this embodiment, the following effects are achieved.

[0030] In this embodiment, the decorative stitch 25 is formed into a substantially L-shape with a corner portion 251, and a recess 212 is formed in the core material 21 as the interior material corresponding to the corner portion 251. Thus, the recess 212 can accommodate the portion of the lower cover 23 that is overlapped by the folded-back end portion.

[0031] In particular, regarding the portion of the decorative stitch 25 formed into an L shape with a corner portion 251, the portion of the lower skin 23 that is overlapped by two pieces due to the folding back is formed into an L shape and becomes thicker, but the thicker portion of the lower skin 23 can be accommodated by the recessed portion 212. As a result, the thicker portion can be prevented from protruding upward, and the portion of the upper skin 22 that is overlapped by two pieces can be prevented from protruding upward and indoor ( Figure 4The right side of the corner portion 101 is protruded and bulged, and the occurrence of the wrinkle is suppressed by the L-shaped configuration of the lower skin 23 and the upper skin 22, so that the shape can be configured to ensure a good appearance.

[0032] Further, in the present embodiment, the upper skin 22 and the lower skin 23 constitute the skin of the door armrest 10. Thereby, the occurrence of the bulging and the wrinkle of the skin at the corner portion 101 of the armrest 10 where the bulging and the wrinkle of the skin are likely to occur can be prevented.

[0033] In addition, the present application is not limited to the above-described embodiments, and variations, modifications, and the like within the scope of achieving the object of the present application are also included in the present application.

[0034] For example, in the present embodiment, the upper skin 22 and the lower skin 23 constitute the skin of the door armrest 10, but are not limited thereto. Further, the decorative stitch 25 is provided to the upper skin 22, but is not limited to this configuration. The decorative stitch can be provided to at least one of the upper skin and the lower skin.
