Description

[Technical Field]

[0001] The present invention relates to a vehicle interior material in which an end portion of a skin material covering a base material is fixed to the base material by a fixing member. [Background technology]

[0002] Conventionally, interior materials for vehicles such as automobiles have been known in which the surface side of a base material made of synthetic resin or the like is covered with a skin material to enhance design. The end portions of the skin material are folded back to the back side of the base material and fixed to the base material with fixing members such as staples (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2004-129743 A (page 3, Figure 4) Summary of the Invention [Problem to be solved by the invention]

[0004] When a substrate has a structure such as a reinforcing rib on the back side and the structure extends to the edge of the skin material folded back to the back side, a cutout may be formed in the edge of the skin material to avoid and expose the structure. Such cutouts are generally rectangular with an opening on the edge side of the skin material. In such cases, if the top of the cutout cannot be fixed to the substrate with fixing members due to layout constraints and both sides of the cutout are fixed to the substrate, the wider spacing between the fixing members sandwiching the cutout can cause bending at the top of the cutout, potentially causing wrinkles that extend to the front side of the vehicle interior material and marring the appearance.

[0005] The present invention has been made in view of the above points, and has as its object to provide a vehicle interior material that has a good appearance and is excellent in durability. [Means for solving the problem]

[0006] The vehicle interior material according to claim 1 comprises a base material, a skin material covering the base material, and a fixing member fixing an end portion of the skin material to the base material, the skin material having a notch at the end portion to expose a part of the base material, the notch having an opening at the edge of the skin material, and a narrow portion having a width dimension smaller than the opening and a minimum width dimension on the inside of the opening, the fixing member being arranged to fix the opening to the narrow portion. the side of the skin material and closer to the narrow portion than the opening in the depth direction of the notch from the edge of the skin material. position to , on both sides of the cutout portion are arranged independently of each other It is something.

[0007] The vehicle interior material according to claim 2 is the vehicle interior material according to claim 1, wherein the cutout portion is formed so that the width dimension gradually decreases from the opening toward the inside of the skin material.

[0008] The vehicle interior material according to claim 3 is the vehicle interior material according to claim 1 or 2, wherein the narrow portion is located at the top of the cutout portion. [Effects of the Invention]

[0009] According to the vehicle interior material of claim 1, the distance between the fixing members located on either side of the cutout can be shortened, which prevents the terminal portion from lifting up near the top of the cutout, thereby preventing wrinkles in the skin material caused by this lifting up and improving the appearance.In addition, even if a tensile force is applied to the periphery of the fixing members in a fixed state, the effect of the tensile force is less likely to extend to the top of the cutout, preventing tearing of the cutout, and resulting in excellent durability.

[0010] According to the vehicle interior material of claim 2, in addition to the effect of the vehicle interior material of claim 1, the opening having a relatively large width makes it easy to align the cutout portion with a part of the base material, and since the width of the opening can absorb small misalignments between the cutout portion and the part of the base material, it becomes easy to align the skin material with the base material, which improves manufacturing workability and makes it easy to form narrow portions that are narrower in width than the opening.

[0011] According to the vehicle interior material of claim 3, in addition to the effects of the vehicle interior material of claim 1 or 2, the fixing member can be fixed to the base material at a position distant from the edge of the skin material, making it more difficult for the skin material to bend near the top of the cutout.

[Figure 4] FIG. 6 is a front view showing a part of a skin material of a vehicle interior material according to a second embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0013] A first embodiment of the present invention will be described below with reference to the drawings.

[0014] 2(a), 2(b), 3(a), and 3(b), reference numeral 1 denotes a vehicle interior material. In this embodiment, the vehicle interior material 1 is used for the interior of a vehicle such as an automobile. In the illustrated example, the vehicle interior material 1 is formed in a rectangular shape elongated in a predetermined direction, but is not limited to this and may be formed in any shape depending on the shape of the arrangement position, the desired design, etc.

[0015] The vehicle interior material 1 is constructed by stacking a base material 2 and a skin material 3. A separate member such as an elastic material (cushion material) may be disposed at least partially between the base material 2 and the skin material 3. The vehicle interior material 1 is disposed such that the skin material 3 side is the occupant side, front side, front side, or design side, and the base material 2 side is disposed such that the vehicle body side, anti-occupant side, rear side, or back side.

[0016] The substrate 2 is molded from a material such as synthetic resin. In this embodiment, the substrate 2 integrally comprises a substrate main body 5 and an extension portion 6 that is continuous with the edge of the substrate main body 5. The substrate main body 5 is formed in a rectangular shape. In this embodiment, the extension portion 6 is continuous and bent in the thickness direction relative to both long sides and one short side of the substrate main body 5. In other words, the extension portion 6 is positioned so as to surround the edge of the substrate main body 5 in a U-shape.

[0017] A structural portion 7 is formed on the substrate 2, spanning the substrate main body portion 5 and the extension portion 6. The structural portion 7 is located on the back side of the substrate 2. In this embodiment, the structural portion 7 is a reinforcing rib. The structural portion 7 is formed in a plate shape, rises from the edge of the substrate main body portion 5 in the thickness direction of the substrate main body portion 5, and extends continuously to the extension portion 6. The end portion of the structural portion 7 is located close to the tip portion of the extension portion 6. In the example shown in the figure, multiple structural portions 7 are arranged spaced apart from each other in the thickness direction.

[0018] At least a portion of the front side of the substrate 2 is covered with the skin material 3. In this embodiment, the entire surface of the substrate main body 5 and the surface of the extension portion 6 of the substrate 2 are covered with the skin material 3.

[0019] The skin material 3 is formed in a sheet shape from any material such as leather or synthetic resin. The skin material 3 has a planar skin material main body 10 that covers the surface of the base material main body 5 and the surface of the extension portion 6 of the base material 2, and a terminal portion 11 that is continuous in a strip shape from the edge of the skin material main body 10. The terminal portion 11 is folded back from the edge of the base material 2, in this embodiment, from the tip of the extension portion 6 and the other short side of the base material main body 5, to the back side of the base material 2 and overlapped thereon.

[0020] The terminal portion 11 extends to a position on the back side of the base material 2 where it may interfere with the structural portion 7. Therefore, as shown in Fig. 1, the terminal portion 11 is formed with a cutout portion 13, which is a relief shape that avoids the structural portion 7. The cutout portion 13 exposes the end of the structural portion 7 that is close to the terminal portion 11.

[0021] The cutout portion 13 has an opening 15 at the tip of the terminal portion 11, which is the edge of the skin 3. In this embodiment, the opening 15 is the portion of the cutout portion 13 with the largest width. The opening 15 has a width W1 of, for example, 28 mm. In the illustrated example, the cutout portion 13 is formed so that the width gradually decreases from the opening 15 toward the inside of the skin 3 (upper side in the figure). In other words, the cutout portion 13 is formed in an expanding shape so that the width gradually increases from the inside of the skin 3 toward the opening 15. That is, the cutout portion 13 has side edges 16, 16 that extend at an angle from both side edges of the opening 15 toward the inside of the skin 3 so as to gradually approach each other. The side edges 16 may be linear, or may be curved in an arc or curve. In this embodiment, the side edges 16 are linear and inclined symmetrically or approximately symmetrically in the width direction of the cutout portion 13. Corners 17 where the side portions 16 and the edges of the covering material 3 (the tips of the terminal portions 11) are joined are curved, for example, in an arc shape. The corners 17 are curved in an arc shape with a diameter of about 0.5 mm.

[0022] Furthermore, cutout portion 13 includes connecting portion 18 connecting side portions 16, 16. Connecting portion 18 has a width W2 that is smaller than width W1 of opening 15. Width W2 is set to, for example, 2 mm. In this embodiment, connecting portion 18 forms the innermost portion, i.e., the top, of cutout portion 13. In the illustrated example, connecting portion 18 is a narrow portion with the smallest width in cutout portion 13. Therefore, in this embodiment, cutout portion 13 is formed so that its width continuously increases from connecting portion 18 toward opening 15.

[0023] The connecting portion 18 is formed, for example, in a straight line that intersects with the side portions 16, 16. Therefore, the cutout portion 13 is formed in a trapezoidal shape. In this embodiment, the connecting portion 18 is located away from the opening 15 toward the inside of the skin 3. The distance between the connecting portion 17 and the opening 15, i.e., the depth dimension D of the cutout portion 13, is formed to be, for example, 11 mm. In addition, the corner portion 19 where the connecting portion 18 and the side portion 16 join is curved, for example, in an arc shape. The curve of the corner portion 19 is an arc shape with a diameter of about 0.5 mm.

[0024] The end portion 11 of the covering material 3 is fixed to the back side of the base material 2 by fixing members 22, with the cutout portion 13 in between, that is, on both sides of the cutout portion 13. In this embodiment, the fixing members 22 are staples that extend along the end portion 11, that is, in a direction intersecting with the side portion 16. However, the fixing members 22 are not limited to this, and may also be rivets, screws, adhesives, or the like.

[0025] The fixing members 22 are located on both sides of the cutout 13, on the opening 15 side of the connecting portion 18. That is, the ends of the fixing members 22 face the side edges 16, 16 except for the corners 17, 19. The fixing members 22 are located closer to the connecting portion 18 than to the opening 15. That is, in the depth direction of the cutout 13 from the edge of the skin 3, the fixing members 22 are located closer to the connecting portion 18 than to the opening 15. In the illustrated example, the fixing members 22 are located closer to the connecting portion 18 than to the center of the cutout 13 in the depth direction. The spacing G between the fixing members 22 in the width direction of the cutout 13 is set to, for example, 15 mm.

[0026] When manufacturing the vehicle interior material 1, a separately formed skin material 3 is attached to a preformed base material 2 so as to cover the front side of the base material 2, and an end portion 11 of the skin material 3 is folded back from the end portion of the base material 2 to the back side of the base material 2. At this time, the base material 2 is positioned so that the cutout portion 13 is located at the position of the structural portion 7 of the base material 2, i.e., so that the structural portion 7 is avoided by the cutout portion 13. Next, using a fixing tool such as a stapler, fixing members 22 are driven into the end portion 11 on both sides of the cutout portion 13 at positions closer to the opening 15 than the connecting portion 18, thereby fixing the base material 2 to the skin material 3.

[0027] In this way, by fixing the upholstery material 3 to the substrate 2 with the fixing members 22 at positions on both sides of the cutout 13 closer to the opening 15 than the connecting portion 18, which is the narrow portion of the cutout 13 formed in the end portion 11 of the upholstery material 3, it is possible to shorten the gap G between the fixing members 22, 22 located on both sides of the cutout 13. This prevents the end portion 11 from lifting up near the top of the cutout 13, thereby preventing wrinkles in the upholstery material 3 due to this lifting and improving the appearance. Furthermore, even if a tensile force is applied to the periphery of the fixing members 22 in the fixed state, the effect of the tensile force is less likely to extend to the connecting portion 18, which is the top of the cutout 13, preventing tearing of the cutout 13, thereby providing a vehicle interior material with excellent durability.

[0028] Furthermore, the cutout portion 13 is formed in a trapezoidal shape with its top serving as a connecting portion 18 extending in a direction intersecting the side portion 16. Therefore, even if the terminal portion 11 of the skin material 3 is pulled in the width direction of the cutout portion 13 when the terminal portion 11 is folded back and wrapped around the back side of the base material 2, the pulling force is dispersed and does not concentrate on the top of the cutout portion 13, thereby preventing tearing from occurring at the top of the cutout portion 13.

[0029] Furthermore, by forming the cutout portion 13 so that its width gradually decreases from the opening 15 toward the inside of the skin material 3, the relatively large width of the opening 15 makes it easier to align the cutout portion 13 with the structural portion 7, and since the width of the opening 15 can absorb small misalignments between the cutout portion 13 and the structural portion 7, it becomes easier to align the skin material 3 with the base material 2, for example, when there are multiple structural portions 7, resulting in good manufacturing workability and enabling the easy formation of narrow portions (connecting portions 18) whose width is smaller than that of the opening 15.

[0030] Furthermore, by positioning connecting portion 18, which is a narrow portion, at the top of cutout portion 13, fixing member 22 can be positioned away from the edge of skin material 3, and skin material 3 can be fixed to base material 2 at a position closer to the front side of vehicle interior material 1, making it more difficult for skin material 3 to bend near the top of cutout portion 13.

[0031] In the first embodiment described above, cutout 13 may be formed in a triangular shape with side edges 16, 16 connected to each other and narrowed to a pointed apex 24, as in the second embodiment shown in Fig. 4. Even in this case, lifting of terminal portion 11 near apex 24 of cutout 13 can be suppressed, thereby suppressing wrinkling of skin material 3 due to this lifting and improving the appearance. In addition, even if a tensile force is applied to the periphery of fixing member 22 in the fixed state, the effect of the tensile force is less likely to extend to apex 24 of cutout 13, preventing tearing of cutout 13. This provides the same effects as the first embodiment, such as excellent durability.

[0032] In each of the above-described embodiments, the cutout portion 13 may be formed in a portion where the width dimension increases toward the inside of the skin material 3, or where the width dimension is constant.

[0033] Furthermore, the narrowed portion does not have to be the top of cutout portion 13. For example, a hollowed-out portion having a width dimension larger than that of connecting portion 18 may be formed on the top side of cutout portion 13 (the end opposite opening 15) connected to connecting portion 18.

[0034] Furthermore, the vehicle interior material 1 is not limited to being used as a console box or part of a center console, but may be used as any vehicle interior material. [Industrial Applicability]

[0035] The present invention can be suitably used as part of a center console provided in the passenger compartment of a vehicle. [Explanation of symbols]
