Description

[Technical Field]

[0001] The present disclosure relates to vehicle interior materials. [Background technology]

[0002] Conventionally, a known technology for vehicle interior materials is described in Patent Document 1. Specifically, Patent Document 1 discloses a vehicle interior material (vehicle interior material) that has a base material and a skin layer provided on the inner space side of the base material, and that has a curved shape that is recessed from the vehicle body panel side toward the inner space side. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2014-121948 Summary of the Invention [Problem to be solved by the invention]

[0004] However, with the configuration disclosed in Patent Document 1, depending on the thickness and texture of the skin material (skin layer), the uneven shape of the base material may be covered by the skin material and become difficult to see, which may result in a reduction in design. Also, light entering the interior of the vehicle through the window glass of the vehicle may hit the skin material and be reflected back toward the window glass, which may result in the vehicle interior material being reflected in the window glass.

[0005] The present disclosure is a technology completed based on the above circumstances, and has as one object to provide a vehicle interior material that can improve design and is less likely to be reflected on window glass. [Means for solving the problem]

[0006] The present disclosure relates to a vehicle interior material comprising a substrate and a skin material provided on the interior side of the substrate, the substrate comprising a main body portion and a structural portion that is convex from the main body portion toward the interior side of the vehicle cabin or concave from the exterior side of the vehicle cabin, the skin material being woven with first yarns and second yarns extending in a direction intersecting the first yarns and having a shape that covers at least the structural portion from the interior side of the vehicle cabin, and the first yarns being configured to reflect light.

[0007] In such a vehicle interior material, the skin material woven with the light-reflecting first and second yarns covers at least the structural part from the inside of the vehicle cabin, so that, for example, if the structural part is convex, the part of the skin material provided on the structural part can be made brighter (glossier) than the part of the main part, and if the structural part is concave, the part of the skin material provided on the structural part can be made darker (matte) than the part of the main part. This makes it easier to create a three-dimensional effect in the structural part, and makes it possible to provide a vehicle interior material equipped with a skin material that can enhance the design shape of the base material.

[0008] In the above configuration, the structural portion may extend in a first direction, and the skin material may cover the structural portion such that the direction in which the first thread extends intersects with the first direction. With this vehicle interior material, light can be reflected along the shape of the structural portion, making it easier to create a three-dimensional effect on the structural portion and improving design.

[0009] In the above configuration, the skin material may be provided on the interior side of the base material so that the extension direction of the first threads is vertical or vertical, and extends in a direction between the interior and exterior of the vehicle. Such a vehicle interior material can suppress light that enters the interior of the vehicle through a window glass and hits the skin material from being reflected back toward the window glass, thereby suppressing reflection of the vehicle interior material on the window glass.

[0010] In the above configuration, the skin material may include an adjacent skin portion adjacent to another skin material provided on the interior side of the vehicle cabin of the other member, the other skin material being formed by weaving the first yarns and the second yarns, and the extending direction of the first yarns in the adjacent skin portion may be the same as the extending direction of the first yarns in the other skin material. With this type of vehicle interior material, the adjacent skin portion and the other skin material can be made to have similar light reflection patterns, such as light and dark colors.

[0011] In the above configuration, the first threads may have a triangular cross section. Such a vehicle interior material can more easily create a three-dimensional effect in the structural portion. [Effects of the Invention]

[0012] According to the present disclosure, it is possible to provide a vehicle interior material that can improve design and that is less likely to be reflected on window glass. [Brief explanation of the drawings]

[0013] [Figure 1] FIG. 1 is a diagram showing a cross-sectional structure of a door trim according to a first embodiment. [Figure 2] Part of the vehicle interior viewed from the left [Figure 3] Enlarged cross-sectional view of a part of the skin material [Figure 4] A diagram showing how light enters through window glass. [Figure 5] FIG. 10 is a view of a part of the interior of a vehicle according to a second embodiment, seen from the left side. DETAILED DESCRIPTION OF THE INVENTION

[0014] <Embodiment 1> A first embodiment of the present disclosure will be described with reference to Figures 1 to 4. In this embodiment, a door trim (vehicle interior material) 100 attached to a door panel that constitutes the door of an automobile (vehicle) will be described. Note that each figure will be described with the arrow direction FR indicating the forward direction, the arrow direction RR indicating the rearward direction, the arrow direction U indicating the upward direction, the arrow direction D indicating the downward direction, the arrow direction IN indicating the inside of the vehicle compartment, and the arrow direction OUT indicating the outside of the vehicle compartment.

[0015] As shown in Fig. 1, the door trim 100 includes a plate-shaped base material 50 and a fabric-like covering material 10 that is thinner than the base material 50 and is attached to the interior surface of the base material 50 using an adhesive or the like. As shown in Fig. 2, in addition to the door trim 100, the vehicle 1 is also provided with an instrument panel 120 that is disposed at the front of the vehicle interior and extends in the left-right direction (vehicle width direction), and multiple window panes 70, 71. The window pane 70 is a power window that can move in the up-down direction, and is the window pane closest to the door trim 100 among the multiple window panes provided in the vehicle 1. The window pane 71 is a windshield that allows occupants to view the road ahead, and is the window pane closest to the instrument panel 120 among the multiple window panes provided in the vehicle 1.

[0016] 1, the base material 50 includes main body portions 51 and 55, two protruding portions 52 and 54 extending from the main body portions 51 and 55 toward the interior of the vehicle cabin, and a recessed portion 53 extending between the two protruding portions 52 and 54 and extending from the main body portions 51 and 55 toward the exterior of the vehicle cabin. The protruding portions 52 and 54 and the recessed portion 53 are examples of structural portions. The material of the base material 50 is not particularly limited, but examples thereof include synthetic resins such as polypropylene, ABS resin, and polyurethane, and materials formed by bonding plant fibers such as kenaf fibers with synthetic resins.

[0017] The main body 51 constitutes the upper portion of the base material 50 and is the portion located near the window glass 70 (see FIG. 2). The protrusion 52 is provided below the main body 51 and above the recess 53. In FIG. 2, the apex of the protrusion 52 (the portion located closest to the interior of the vehicle) is indicated by a dashed dotted line. The protrusion 52 extends in the front-to-rear direction (first direction). As shown in FIG. 1, the protrusion 54 is provided below the recess 53 and serves as an armrest on which a passenger can place their arm.

[0018] The skin material 10 includes an upper skin portion 12 that covers the convex portions 52 from the inside of the vehicle cabin, a middle skin portion 13 that covers the concave portions 53 from the inside of the vehicle cabin, and a lower skin portion 14 that covers the convex portions 54 from the inside of the vehicle cabin. As shown in FIG. 3, the skin material 10 is a woven fabric formed by weaving multiple warp threads (first threads) 10A and multiple weft threads (second threads) 10B. The weft threads 10B are woven together with the warp threads 10A so as to extend in a direction (front-to-rear direction) that intersects the direction in which the warp threads 10A extend (the direction toward the front of the page: the vertical direction of the vehicle cabin), thereby forming the skin material 10. The weaving method of the warp threads 10A and the weft threads 10B is not particularly limited and may be, for example, a plain weave, a twill weave, or a satin weave. Note that FIG. 3 shows a cross section of the warp threads 10A.

[0019] 2, for the sake of convenience, the multiple warp threads 10A are shown in stripes in the skin material 10. The skin material 10 covers the convex portions 52 so that the extension direction of the warp threads 10A extends in a vertical direction intersecting with the front-rear direction (first direction) in which the convex portions 52 extend. The skin material 10 is attached to the base material 50 so that the extension direction of the warp threads 10A is aligned with a line L1 connecting a seat 80 provided in the vehicle interior and a window glass 70 provided near the door trim 100.

[0020] The material of the warp threads 10A and the weft threads 10B is not particularly limited, but may be, for example, a thread made by twisting fibrous synthetic resins. This synthetic resin may be one or more synthetic resins selected from the group consisting of polyesters such as polyethylene, polypropylene, and polyethylene terephthalate; thermoplastic resins such as nylon, polystyrene, polycarbonate, methacrylic resin, polyvinyl chloride, and fluorine-containing resin; and thermosetting resins such as epoxy resin and silicone resin. Among these, polyethylene terephthalate is preferred. The materials of the warp threads 10A and the weft threads 10B may be the same or different.

[0021] The warp threads 10A are configured to reflect light. As shown in FIG. 3, the warp threads 10A have three surfaces 10A1 and have a triangular cross section in the radial direction. The weft threads 10B have a circular cross section in the radial direction and have a curved surface 10B1. The surface 10A1 of the warp threads 10A is flatter than the curved surface 10B1 of the weft threads 10B. In FIG. 3, the multiple warp threads 10A are oriented with their vertices pointing upward, but this is not limiting, and the multiple warp threads 10A may be oriented with their vertices pointing in different directions.

[0022] The warp yarns 10A use fibers with a relatively small diameter, thereby increasing their surface area and increasing their reflectivity compared to the weft yarns 10B. The diameter of the fibers of such warp yarns 10A is preferably 1 μm or more, more preferably 1.5 μm or more, even more preferably 2 μm or more, and preferably 10 μm or less, more preferably 7 μm or less, and even more preferably 5 μm or less. The diameter of the fibers of weft yarns 10B is preferably 6 μm or more, more preferably 8 μm or more, even more preferably 10 μm or more, and preferably 50 μm or less, more preferably 40 μm or less, and even more preferably 30 μm or less. The reflectivity of the entire covering material 10 is preferably 80% or more, and preferably 85% or more.

[0023] In FIG. 4, the weft yarns 10B of the covering material 10 are omitted. As shown in FIG. 4, the covering material 10 is arranged so that the extending direction L2 of the warp yarns 10A intersects at an angle θ with a line (extending in the front-rear direction) L3 parallel to the window glass 70 provided near the door trim 100 (a line extending in the front-rear direction). This angle θ is preferably 60 degrees or more, more preferably 75 degrees or more, and even more preferably 90 degrees. When the angle θ is such a value, light incident from the window glass 70 (indicated by the dashed-dotted arrow) strikes the surface 10A1 of the warp yarns 10A and is easily diffused in the front-rear direction. This prevents the light incident from the window glass 70 from being reflected by the surface 10A1 toward the window glass 70, thereby preventing the covering material 10 from being reflected in the window glass 70 and being visible to the occupant H. In this embodiment, the angle θ is 90 degrees.

[0024] Next, the effects of this embodiment will be described. In this embodiment, a door trim 100 is shown, which includes a substrate 50 and a skin material 10 provided on the interior side of the substrate 50, the substrate 50 including main bodies 51 and 55, protrusions 52 and 54 extending from the main bodies 51 and 55 toward the interior of the vehicle, and a recess 53 extending from the main bodies 51 and 55 toward the exterior of the vehicle, the skin material 10 being woven with warp threads 10A and weft threads 10B extending in a direction intersecting the warp threads 10A, and covering the protrusions 52 and 54 and the recess 53 from the interior side of the vehicle, and the warp threads 10A are configured to reflect light.

[0025] In this door trim 100, the skin material 10 formed by weaving light-reflecting warp threads 10A and weft threads 10B covers the convex portions 52, 54 from the inside of the vehicle cabin, so that the portions 12, 14 of the skin material 10 provided on the convex portions 52, 54 can be made glossier than the portions of the skin material 10 provided on the main portions 51, 55. Furthermore, because the skin material 10 covers the concave portions 53 from the inside of the vehicle cabin, the portions 13 of the skin material 10 provided on the concave portions 53 can be made more matte than the portions of the skin material 10 provided on the main portions 51, 55. This makes it easier to create a three-dimensional effect in the convex portions 52, 54 and the concave portions 53, and makes it possible to provide a door trim 100 equipped with the skin material 10 that can enhance the design shape of the base material 50.

[0026] The protrusions 52 extend in a first direction, which is the front-to-rear direction, and the skin material 10 covers the protrusions 52 so that the direction in which the warp threads 10A extend intersects with the first direction. With this door trim 100, light can be reflected along the shape of the protrusions 52, making it easier to create a three-dimensional effect for the protrusions 52 and improving the design.

[0027] The skin material 10 is provided on the interior side of the base material 50 so that the extension direction of the warp threads 10A extends in the vertical direction. Such a door trim 100 prevents light that enters the interior of the vehicle through the window glass 70 and hits the skin material 10 from being reflected back toward the window glass 70, thereby preventing the door trim 100 from being reflected in the window glass 70.

[0028] The warp threads 10A have a triangular cross section. According to this door trim 100, the protrusions 52, 54 and the recess 53 can more easily create a three-dimensional effect.

[0029] <Embodiment 2> Next, a second embodiment of the present disclosure will be described with reference to Fig. 5. In this embodiment, the same components as those in the above embodiment are designated by the same reference numerals, and redundant explanations of the structure, operation, and effects will be omitted.

[0030] The vehicle 201 includes a plurality of vehicle interior materials such as a door trim 200 and an instrument panel (other component) 220. The instrument panel 220 includes a base material 221 and an other skin material 222 attached to the interior side of the vehicle cabin of the base material 221. The other skin material 222 is a woven fabric formed by weaving warp threads 222A having a configuration similar to that of the warp threads 10A in the first embodiment and weft threads (not shown) having a configuration similar to that of the weft threads 10B. The other skin material 222 is attached to the base material 221 so that the warp threads 222A extend in an oblique direction.

[0031] The door trim 200 extends rearward from a lateral end of the instrument panel 220. The door trim 200 includes a base material 50 (see FIG. 1 ) and a skin material 210 attached to the interior side of the base material 50. The skin material 210 is a woven fabric formed by weaving warp threads 210A having a configuration similar to that of the warp threads 10A in the first embodiment and weft threads (not shown) having a configuration similar to that of the weft threads 10B. The skin material 210 is attached to the base material 50 so that the warp threads 210A extend in an oblique direction. The skin material 210 includes an adjacent skin portion 215 adjacent to the other skin material 222. The extension direction of the warp threads 210A in the adjacent skin portion 215 is aligned with the extension direction of the warp threads 222A in the other skin material 222. According to this door trim 200, it is possible to make the light reflection characteristics, such as the brightness and darkness of the colors, similar between the adjacent skin portion 215 and the other skin material 222. The extending direction of the warp threads 210A in the skin material 210 may be along the extending direction of the warp threads 222A in the other skin material 222 as a whole, even in the portion other than the adjacent skin portion 215.

[0032] <Other embodiments> The present disclosure is not limited to the embodiments described above and in the drawings, and for example, the following embodiments are also included within the technical scope of the present disclosure. Furthermore, various modifications other than those described below can be made without departing from the spirit of the present disclosure.
