Description

[Technical field]

[0001] The present invention relates to an interior part of a vehicle. [Background technology]

[0002] In vehicle interior parts, the surface of a substrate is covered with a skin material. Conventionally, in order to improve the design of the interior parts and to achieve more reliable welding between the substrate and the skin material, techniques have been proposed relating to a method of forming the skin material and a method of holding the skin material to the substrate.

[0003] For example, Patent Document 1 discloses an interior material including a base material having a main body, a flange, and a support rib, and a skin body that covers the base material and is fixed to the base material. In this interior material, the end portion of the skin body with the flange portion rolled in is pushed along a guide portion that protrudes inward from the flange portion, so that the end portion is guided by the guide portion and sandwiched between the support rib and the flange portion. As a result, it is said that the end portion of the skin body can be easily and reliably held against the base material. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2017-114261 A Summary of the Invention [Problem to be solved by the invention]

[0005] Incidentally, in the terminal portion of the interior parts of conventional vehicles, the skin material is folded and stored on the back surface of the base material. In this case, if the terminal of the base material has an acute angle shape, the part of the skin material that contacts the terminal of the base material may tear or whiten. For this reason, the shape of the terminal is avoided from having an acute angle shape, and is made to have a large corner R shape (i.e., a shape with an obtuse angle with a large corner curve). On the other hand, from the viewpoint of design, there are cases where it is desirable to make the terminal of the interior part have a more acute angle shape.

[0006] Therefore, this specification provides an interior part for a vehicle that does not cause tearing or whitening of the skin material at the terminal portion of the skin material covering the base material, even if the terminal of the base material has an acute angle. [Means for solving the problem]

[0007] The vehicle interior part disclosed in this specification comprises a base material and a skin material covering at least a portion of the base material, a rib is provided on the back surface of the base material at an end thereof, and the end portion of the skin material is wrapped around the back surface of the base material and welded to the base material, including the rib.

[0008] According to the above-mentioned configuration, even if the end of the base material has an acute angle, the end portion of the skin material does not need to be folded because the end portion of the skin material is rolled up into the back surface of the base material and welded to the rib, which prevents the occurrence of tearing or whitening in the part of the skin material that contacts the end of the base material.

[0009] In the vehicle interior part, the side wall of the rib is disposed at a position spaced apart from a peripheral edge of the terminal of the base material.

[0010] The vehicle interior part is also characterized in that the base material is tapered toward the terminal, and the rib is positioned approximately in the center in a direction perpendicular to the direction toward the tip of the tapered shape.

[0011] According to the above-mentioned configuration, it is possible to prevent the end portion of the skin material wrapped around the back surface of the base material from appearing on the design surface while still allowing the design lines of the interior part to stand out. Effect of the Invention

[0012] According to the vehicle interior part disclosed in this specification, at the end portion of the skin material covering the base material, the end of the base material can be formed into an acute-angled shape, and tearing or whitening of the skin material can be prevented.

[Diagram 3] FIG. 2 is a schematic perspective view showing a rear surface of an interior part of a vehicle. [Figure 4] 13A and 13B are diagrams showing how the skin material is welded to the rib. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] Hereinafter, vehicle interior parts will be described with reference to the drawings. In each drawing, "Fr", "Up", and "Rh" indicate the front, upper, and right side of the vehicle, respectively.

[0015] Fig. 1 is a schematic diagram of the inside of a vehicle in which an interior part is provided. As shown in Fig. 1, an air conditioner outlet 12 is provided at the right end in the vehicle width direction of an instrument panel of a vehicle 10. An interior part 14 is disposed immediately below the air conditioner outlet 12. More specifically, the interior part 14 of the vehicle 10 is located behind the air conditioner outlet 12, and its outer end face in the vehicle width direction is provided at a position facing a vehicle body side part 16 such as a door or a front pillar. In Fig. 1, the interior part 14 is shown surrounded by a dashed line.

[0016] In this example, the "substrate" in the claims is the main body of the interior part 14. However, the vehicle interior parts disclosed in this specification are not limited to this. Here, as an example of the substrate, a member provided directly below the air conditioner outlet as shown in FIG. 1 is exemplified. However, the substrate may be, for example, another decorative part of the instrument panel or the lid of a console box. In other words, the substrate in the claims can be applied to various interior parts in a vehicle.

[0017] Next, the interior part 14 will be further described with reference to Figs. 2 and 3. Fig. 2 is a schematic perspective view of the interior part of the vehicle as viewed from below the vehicle. Fig. 3 is a schematic perspective view of the back side of the interior part of the vehicle. As shown in Figs. 2 and 3, the interior part 14 of the vehicle 10 includes a base material 18 and a skin material 20. In this example, the base material 18 is a member provided directly below the air outlet 12 of the air conditioner. The skin material 20 is a member that covers at least a part of the base material 18. The materials of the base material 18 and the skin material 20 are not particularly limited, and it is sufficient that the skin material 20 can be welded to the surface of the base material 18. In Figs. 2 and 3, the base material 18 is covered with the skin material 20, so the reference numerals are shown in parentheses. The skin material 20 is shown in light ink.

[0018] As shown in Figures 2 and 3, ribs 22 are provided on the rear surface at the terminals of the base material 18. In this example, the ribs 22 are integrally formed with the base material 18. The ribs 22 are reinforcing members that extend perpendicular to the surface (i.e., the design surface) of the base material 18. In Figures 2-4, the ribs 22 are indicated by dark black portions.

[0019] As shown in Fig. 2, the vehicle interior part disclosed in this specification has an acute-angled shape realized at the end of the base material 18 covered with the skin material 20. In Fig. 2, the extension lines of two adjacent sides of the outline of the base material 18 are shown by dashed lines. That is, the dashed lines shown in Fig. 2 indicate that the angle at which the dashed lines intersect is an acute angle, in other words, that the end of the base material 18 has an acute-angled shape.

[0020] As described above, in order to form the end of the base material 18 into an acute-angled shape and then weld the skin material 20 to the surface of the base material 18, the rib 22 is required. The rib 22 in this example extends toward the acute-angled end. This configuration will be further described with reference to FIG. 4.

[0021] Fig. 4 is a diagram showing how the skin material is welded to the rib. Fig. 4 shows the back side of the base material 18. In Fig. 4, the allowances for welding the end portion of the skin material 20 to the back side of the base material 18 are shown as welding allowances 20a and 20b. The skin material 20 and the welding allowances 20a and 20b, which are parts of the skin material 20, are shown in light ink and surrounded by a two-dot chain line to distinguish the boundaries with other members. Compared to the welding allowance 20a, the welding allowance 20b is shown in a lighter color.

[0022] Conventionally, in order to ensure design in vehicle interior parts, the surface of a substrate is covered with a skin material, and an end of the skin material is wrapped around the back side of the substrate. In this example, the surface of substrate 18 is covered with skin material 20, and an end portion of skin material 20 is wrapped around the back side of substrate 18. Then, the end portion of skin material 20 wrapped around the back side is welded to substrate 18, including rib 22. Figure 4 shows the welding process from top to bottom.

[0023] The topmost figure in FIG. 4 shows a state where the skin material 20 is fitted to the substrate 18 (i.e., the skin material 20 covers the surface of the substrate 18). In this figure, the welding margins 20a and 20b are in a state before being rolled up around the back surface of the substrate 18. The second figure from the top in FIG. 4 shows a state where the welding margin 20a is rolled up around the back surface of the substrate 18 and welded. The third figure from the top in FIG. 4 shows a state where the welding margin 20b is rolled up around the back surface of the substrate 18 and welded. As can be seen from this figure, the end portion of the skin material 20 is left over near the tip portion of the substrate 18. That is, the welding margins 20a and 20b have leftover skin portions. Here, if the substrate 18 does not have the rib 22, the leftover skin portion at the end of the skin material 20 is folded and stored on the back surface of the substrate 18. However, in such a case, an extra space for storing the leftover skin portion may be required on the back surface of the substrate 18. In addition, when the tip of the substrate 18 is tapered as in this example, that is, when the end is acutely shaped, force is applied to the skin 20 when folding the excess skin at the end of the skin 20, which may cause tearing or whitening. However, in this example, the substrate 18 is provided with a rib 22, so that the excess skin can be welded to the substrate 18 including the rib 22 without folding, as shown by the two black arrows in the third diagram from the top of FIG. 4. Next, the diagram at the bottom of FIG. 4 shows the state in which the skin 20 is welded to the substrate 18 including the rib 22. As can be seen from this diagram, the excess skin at the end of the skin 20 is welded after being wrapped around the surface and side of the rib 22.

[0024] As described above, the end of the base material 18 has an acute angled shape, but the end portion of the skin material 20 is wrapped around the back surface of the base material 18 and welded to the rib 22. In other words, the end portion of the skin material 20 can be stored along the rib 22. Therefore, there is no need to fold the end portion of the skin material 20. As a result, it is possible to prevent tearing or whitening in the portion of the skin material 20 that contacts the end of the base material 18.

[0025] As shown in FIG. 4, the sidewall of the rib 22 is disposed at a position spaced apart from the periphery of the terminal of the base material 18. The base material 18 is tapered toward the terminal, and the rib 22 is disposed at approximately the center in a direction perpendicular to the direction toward the tip of the tapered shape. For example, when the rib 22 is along one side of the base material 18 (i.e., when the rib 22 is shaped to extend from the side of the base material 18), the skin portion of the skin material 20 that has been subjected to the terminal treatment may be visible through the gap between the parts. However, from the viewpoint of design, it is necessary to prevent such an excess portion of the skin material 20 that is rolled up on the back surface of the base material 18 from being visible from the design surface. Therefore, the sidewall of the rib 22 is disposed at a position spaced apart from the periphery of the terminal of the base material 18 (for example, approximately the center of two adjacent sides in the outline of the base material 18 as shown in FIG. 4).

[0026] The above description is merely an example, and the vehicle interior part disclosed in this specification may have any configuration in which the end portion of the skin material is wrapped around the back surface of the base material and welded to the base material including the rib. Therefore, other configurations of the vehicle interior part may be changed as appropriate.

[0027] For example, in the embodiment, the shape of the rib 22 is shown as a triangle, but is not limited thereto. The rib 22 may be capable of rolling up the excess part at the end of the skin material 20. In other words, the shape of the rib 22 is not particularly limited as long as it has an area large enough to weld the excess skin at the end of the skin material 20. Therefore, the shape of the rib 22 may be, in addition to a triangle, a rod shape having a rectangular cross section with a major axis and a minor axis. [Explanation of symbols]
