Description

Skin Material and Automotive Interior Component

[0001] The present disclosure relates to a skin material provided on the surface of an automotive interior component and an automotive interior component having the skin material.

[0002] Automotive interior components such as instrument panels and door trims comprise a base material formed of a resin material such as PP or ABS, and a skin material formed of a resin material such as urethane that covers the surface of the base material to form a design surface. Decorative patterns such as seam patterns and grain patterns are provided on the surface (first surface) of the skin material. For example, Patent Document 1 describes an invention of a method for producing a fiber-reinforced resin molded article and the molded article, wherein an outer layer is formed by applying a fiber-reinforced resin mixed with reinforcing fibers onto a surface layer serving as the outermost skin of the molded article, then clamping the mold and injecting a resin containing no reinforcing fibers into the mold cavity to form an inner layer.

[0003] Japanese Patent No. 6609143

[0004] Although such a molded article can achieve satisfactory durability, it increases the number of manufacturing steps, leading to increased time and cost, and it has been difficult to adapt to the required mechanical properties (particularly tensile strength).

[0005] Accordingly, an object of the present disclosure is to provide a skin material and an automotive interior component that have a simple structure and can improve the degree of freedom in adapting to the required mechanical strength.

[0006] To achieve the above objective, the first configuration of the present disclosure is a surface material formed from a resin material and laminated directly or indirectly onto a substrate of a predetermined shape, comprising a first surface on the front side which is the design surface, and a second surface on the substrate side, wherein a reinforcing material is embedded in a predetermined region in the surface direction on at least one of the first surface and the second surface. Another embodiment of the first configuration is characterized in that, in the above configuration, the reinforcing material is embedded in the second surface and exposed on the second surface. Another embodiment of the first configuration is characterized in that, in the above configuration, the substrate has a bendable deformation portion, and the reinforcing material is arranged in the region corresponding to the bendable deformation portion. Another embodiment of the first configuration is characterized in that, in the above configuration, the bendable deformation portion has a shape that is convex outward, and the reinforcing material is also embedded in the region corresponding to the peripheral edge of the bendable deformation portion. Another embodiment of the first configuration is characterized in that, in the above configuration, there is a recess opening to the second surface, and the reinforcing material is embedded in the bottom surface and / or side surface of the recess. Another aspect of the first configuration is characterized in that, in the above configuration, the reinforcing material has a protrusion projecting from the second surface, and the reinforcing material is embedded in the protrusion. Another aspect of the first configuration is characterized in that, in the above configuration, the reinforcing material is laminated on the substrate having a light source and is translucent, and the reinforcing material is embedded in a predetermined light-transmitting region on the second surface facing the light source. Another aspect of the first configuration is characterized in that, in the above configuration, the reinforcing material is laminated on the substrate having a light source and is translucent, and the reinforcing material is embedded in a predetermined non-light-transmitting region on the second surface other than the predetermined light-transmitting region facing the light source. Another aspect of the first configuration is characterized in that, in the above configuration, the reinforcing material is a nonwoven fabric or a woven fabric. Another aspect of the first configuration is characterized in that, in the above configuration, the reinforcing material is a film. Another aspect of the first configuration is characterized in that, in the above configuration, a second reinforcing material of a different type from the reinforcing material is embedded in a region other than the predetermined region. Another aspect of the first configuration is characterized in that, in the above configuration, a textured pattern is formed on the first surface.To achieve the above objective, the second configuration of this disclosure is an automotive interior part characterized in that a surface material described in any of the first configurations is laminated onto a base material having a predetermined shape.

[0007] According to this disclosure, the mechanical strength of the surface material can be improved simply by providing reinforcing materials, leading to a reduction in manufacturing man-hours. Furthermore, by selecting the application area of ​​the reinforcing materials, the mechanical strength can be increased in the necessary areas. Therefore, a simple structure can be used to improve the degree of freedom in adapting to the required mechanical strength. According to another aspect of this disclosure, in addition to the above effects, since the reinforcing materials are embedded in and exposed on the second surface, the design of the first surface is not impaired even when reinforcing materials are provided, and a positioning effect is also obtained by the reinforcing materials exposed on the second surface contacting the base material. According to another aspect of this disclosure, in addition to the above effects, since the reinforcing materials are placed in the area corresponding to the bending deformation part of the base material, the mechanical strength of the part that deforms in accordance with the bending deformation part can be maintained. According to another aspect of this disclosure, in addition to the above effects, since the reinforcing materials are also embedded in the area corresponding to the peripheral edge of the bending deformation part that protrudes outward, the mechanical strength of the deformed part can be further improved. According to another aspect of this disclosure, in addition to the above effects, since the reinforcing materials are embedded in the bottom surface and / or side surface of the recess that opens to the second surface, a reinforcement effect of the recess can be obtained. According to another aspect of this disclosure, in addition to the above effects, the reinforcing material is embedded in the protrusions protruding from the second surface, thus providing a reinforcing effect on the protrusions. According to another aspect of this disclosure, in addition to the above effects, the reinforcing material is embedded in a light-transmitting region facing a light source provided on the substrate, so the amount of light transmitted to the light-transmitting region changes as it passes through the reinforcing material, allowing for shading even with the same light source. According to another aspect of this disclosure, in addition to the above effects, the reinforcing material is embedded in a non-light-transmitting region, so the reinforcing material can be given a shielding function that blocks light from the light source. Therefore, the luminescence in the light-transmitting region can be made more noticeable. According to another aspect of this disclosure, in addition to the above effects, the reinforcing material is a nonwoven fabric, woven fabric, or film, so the reinforcing material can be easily obtained. According to another aspect of this disclosure, in addition to the above effects, the second reinforcing material is embedded in a region other than the predetermined region, so it is possible to select the reinforcing material according to the part to be reinforced and provide appropriate reinforcement. According to another aspect of this disclosure, in addition to the above effects, a textured pattern is formed on the first surface, thus enhancing the design aesthetics.

These are enlarged cross-sectional views of the external deformation tolerance portion and the internal deformation tolerance portion. These are explanatory diagrams of the armrest manufacturing method and the surface material, with Figure 3A showing the molding state by the injection molding apparatus and Figure 3B showing the surface material after it has been removed and turned upside down.

This is a partially enlarged cross-sectional view of the display operation section showing a modified example of Example 2.

[0009] The embodiments of this disclosure will be described below with reference to the drawings. In Example 2, the same reference numerals are used for components common to Example 1, and redundant descriptions are omitted.

[0010] Figure 1 is a cross-sectional view of an armrest 1, which is an example of an automotive interior part (hereinafter simply referred to as "interior part"). The armrest 1 is provided on the upper part of the center console between the driver's seat and the passenger seat of the automobile and has a rectangular shape in plan view that extends in the front-to-back direction. A recessed portion 2 that is recessed upward is formed on the lower surface of the armrest 1. For the sake of explanation, the right side of Figure 1 will be described as the front, the left side as the rear, the upper side as the up, and the lower side as the down. The armrest 1 has a base material 10, a core material 20, and a surface material 30 that covers the surfaces of the base material 10 and the core material 20. The base material 10 is a molded product of a resin material such as PP or ABS. The base material 10 is provided at the bottom of the armrest 1. The base material 10 has an upper plate portion 11, a side plate portion 12, and a lower plate portion 13.

[0011] The upper plate portion 11 is located in the center of the base material 10 and forms the ceiling surface of the recessed portion 2. The side plate portion 12 forms a curved portion 3 that moves downward as it moves outward from the outer circumference of the upper plate portion 11, and then extends downward to form the side surface of the recessed portion 2. The lower plate portion 13 extends horizontally outward in the front, back, left, and right directions from the lower end of the side plate portion 12. At both the front and rear ends of the lower plate portion 13, semicircular protrusions 14, 14 are formed in the left-right direction. The tip of each protrusion 14 has a rounded cross-sectional shape and forms an outer corner portion 15 with a small radius that curves outward. Between the side plate portion 12 and the lower plate portion 13, an inner corner portion 16 with a small radius that curves outward is formed around the entire circumference. The radius of curvature between the outer corner portion 15 and the inner corner portion 16 is set to, for example, 2 mm. This radius of curvature is selected within the range of 1.5 mm to 10 mm depending on the type of interior fitting. The outer corner portion 15 and the inner corner portion 16 are examples of the bent deformation portion of the base material of this disclosure.

[0012] The core material 20 is a molded product of a cushioning resin material, such as urethane. The core material 20 covers the entire upper surface of the base material 10 and has an outer shape that matches the armrest 1.

[0013] The surface material 30 is a molded product of a resin material such as elastomer, and has a softness such that its Shore A hardness is, for example, 30. The Shore A hardness is selected in the range of 5 to 80 depending on the type of interior part. The surface material 30 is in the form of a sheet with a predetermined thickness, comprising a first surface 31 which is the design surface and a second surface 32 which is laminated on the base material 10 and the core material 20. The surface material 30 also has an outer skin portion 33 and four inner skin portions 34, 34... The outer skin portion 33 has the first surface 31 facing outwards and the second surface 32 laminated on the entire upper surface of the core material 20, covering the upper surface and the outer surfaces of the front, back, left, and right of the armrest 1. Each inner skin portion 34 extends from the four outer edges of the outer skin portion 33, and is folded inwards from the tip of the protruding portion 14 of the lower plate portion 13, then folded upwards at the position of the inner corner portion 16 and bonded to the side plate portion 12. Therefore, the folded portion on the outside of the inner skin portion 34 becomes an external deformation-allowing portion 35 that curves along the outer corner portion 15. Also, the folded portion on the inside of the inner skin portion 34 becomes an internal deformation-allowing portion 36 that curves along the inner corner portion 16.

[0014] Figure 2 is an enlarged cross-sectional view of the external deformation-tolerant portion 35 and the internal deformation-tolerant portion 36 in Figure 1. A reinforcing material 40 is embedded over substantially the entire surface 32 of the surface material 30 and is exposed on the second surface 32. Here, a nonwoven fabric (for example, gauze) is used as the reinforcing material 40. In addition to nonwoven fabric, woven fabric and film can also be used as the reinforcing material. A recess 37 is formed on the second surface 32 side of the external deformation-tolerant portion 35. The recess 37 opens in the region corresponding to the top 15a, which is the most protruding part of the outer corner portion 15 toward the external deformation-tolerant portion 35, and extends in the left-right direction, which is the direction of the ridge of the top 15a. Similarly, a recess 38 is formed on the second surface 32 side of the internal deformation-tolerant portion 36. The recess 38 opens in the region corresponding to the top 16a, which is the most protruding part of the inner corner portion 16 toward the internal deformation-tolerant portion 36, and extends in the left-right direction, which is the direction of the ridge of the top 16a. The reinforcing material 40 is also embedded in the recesses 37 and 38, extending across the bottom and side surfaces, respectively.

[0015] Because the outer corner 15 and inner corner 16 have a curved shape with a small radius of curvature, when folding the inner skin portion 34, which does not have recesses 37 and 38, to match these, it becomes difficult to deform due to the material's rigidity. However, by forming the outer deformation-allowable portion 35 and the inner deformation-allowable portion 36, which have recesses 37 and 38, the rigidity of the folded portion is reduced, making it easier to deform and allowing for easy installation. Furthermore, even if the wall becomes thinner by forming the recesses 37 and 38, the necessary mechanical strength can be ensured because the reinforcing material 40 is embedded.

[0016] The formation of the surface material 30 is carried out in the following steps. The surface material 30 is injection molded by an injection molding apparatus (hereinafter referred to as "molding apparatus") 50, for example, as shown in Figure 3. The molding apparatus 50 has a cavity 53 for forming the surface material 30 between an inner mold 51 and an outer mold 52, and resin material can be injected into the cavity 53 from an injection port (not shown). Figure 3A shows an enlarged view of the part where the external deformation allowance 35 is formed. The cavity 53 has a curved shape corresponding to the curved shape of the external deformation allowance 35. The inner surface 53a of the cavity 53 on the inner mold 51 side forms the first surface 31 of the surface material 30. Therefore, if a textured pattern is to be formed on the first surface 31, the inner surface 53a is textured. The inner surface 53b of the cavity 53 on the outer mold 52 side forms the second surface 32 of the surface material 30. Therefore, a protrusion 54 for forming a recess 37 is formed in the portion of the inner surface 53b that is the region of the external deformation allowable portion 35. The reinforcing material 40 is set in the cavity 53 along the inner surface 53b of the inner mold 51, which includes the protrusion 54.

[0017] When resin material is injected into the cavity 53 by this molding apparatus 50 and molded, a surface material 30 with recesses 37 formed on its surface is obtained. If the outer mold 52 is divided into split molds 52A and 52B, a parting line PL will be formed on the surface along the mating surface of the split molds. After removing this surface material 30 from the cavity 53, as shown in Figure 3B, when the surface material 30 is inverted to expose the first surface 31, the recesses 37 are formed on the inside of the external deformation allowance portion 35 (on the second surface 32 side), and the parting line PL is formed on the inner surface and not exposed, resulting in a surface material 30. The same applies to the internal deformation allowance portion 36. Therefore, when the inverted surface material 30 is laminated and attached to the base material 10 and core material 20 as shown in Figures 1 and 2, an armrest 1 is obtained in which a textured pattern 39 is formed on the first surface 31 and a reinforcing material 40 is embedded in the second surface 32.

[0018] The surface material 30 of Example 1 is formed from a resin material and laminated directly or indirectly via a core material 20 onto a base material 10 of a predetermined shape. The surface material 30 comprises a first surface 31 on the front side which serves as the design surface, and a second surface 32 on the base material 10 side, with reinforcing material 40 embedded in substantially the entire surface area of ​​the second surface 32. With this configuration, the mechanical strength of the surface material 30 can be improved simply by providing the reinforcing material 40, leading to a reduction in manufacturing man-hours. Furthermore, by selecting the application area of ​​the reinforcing material 40, the mechanical strength can be increased in the necessary areas. Thus, a simple structure can be used to improve the degree of freedom in adapting to the required mechanical strength.

[0019] The reinforcing material 40 is embedded in the second surface 32 and exposed on the second surface 32. Therefore, even if the reinforcing material 40 is provided, the aesthetic appearance of the first surface 31 is not impaired, and the reinforcing material 40 exposed on the second surface 32 contacts the base material 10, providing a positioning function relative to the base material 10. The base material 10 has an outer corner portion 15 and an inner corner portion 16, and the reinforcing material 40 is positioned in the areas corresponding to the outer corner portion 15 and the inner corner portion 16. Therefore, the mechanical strength of the outer deformation allowable portion 35 and the inner deformation allowable portion 36, which deform in accordance with the outer corner portion 15 and the inner corner portion 16, can be maintained. The outer corner portion 15 and the inner corner portion 16 have a shape that is convex outward, and the reinforcing material 40 is also embedded in the areas corresponding to the periphery of the outer corner portion 15 and the inner corner portion 16. Therefore, the mechanical strength of the outer deformation allowable portion 35 and the inner deformation allowable portion 36 can be further improved. The second surface 32 has recesses 37 and 38 that open to it, and the reinforcing material 40 is embedded in the bottom and side surfaces of the recesses 37 and 38. Therefore, a reinforcing effect on the recesses 37 and 38 is also obtained. The reinforcing material is a nonwoven fabric, woven fabric, or film. Therefore, the reinforcing material can be easily obtained. The first surface 31 has a textured pattern 39 formed on it. Therefore, the design is enhanced.

[0020] In Example 1, the reinforcing material provided on the second surface does not need to be exposed on the second surface. The reinforcing material is not limited to being provided on the second surface side; as shown in Figure 4, it may be provided on the first surface 31 side of the reinforcing material 40, or as shown in Figure 5, the reinforcing material 40 may be provided on both sides of the first surface 31 and the second surface 32. The reinforcing material does not need to be provided over the entire surface of the first surface and / or the second surface. For example, in the armrest 1, the reinforcing material 40 may be provided only on either the external deformation-tolerant portion 35 and the internal deformation-tolerant portion 36, or on the front, rear, left, and right curved portions 3, 3. Alternatively, the reinforcing material 40 may be provided only on the periphery of the external deformation-tolerant portion 35 and the internal deformation-tolerant portion (recess 37 and recess 38). The reinforcing material in the recess is not limited to the entire bottom and side surfaces of the recess; for example, it may be provided only on the bottom surface or the side surfaces. The reinforcing material is not limited to the area corresponding to the bending deformation portion of the base material; it may also be provided in areas where the surface material itself is thin. A core material is not required.

[0021] Figure 6 is a partial perspective view of an armrest 1A, which is another example of an interior component, provided on a door panel. The armrest 1A is provided on the inside of the car door and includes a display and operation section 60 in which a surface material 30A is laminated on the surface of a base material 10. Figure 7 is a partially enlarged cross-sectional view of the display and operation section 60. The surface material 30A here is a molded product of a resin material such as a light-transmitting elastomer, and the second surface 32 is laminated to the base material 10 without adhesive. A textured pattern 39 is formed on the first surface 31. A circular housing recess 61 that is recessed inward is integrally formed on the base material 10. A light source 62 is housed in the housing recess 61. The light source 62 is formed, for example, from one or more LEDs. An outlet 63 for lead wires 64 connected to the light source 62 is formed at the bottom of the housing recess 61.

[0022] In the surface material 30A, a partition projection 65 projecting downward is integrally formed on the second surface 32. The partition projection 65 is cylindrical and reaches into the housing recess 61, where the light source 62 is housed. The partition projection 65 is an example of a projection in this disclosure. The reinforcing material 40 here is embedded over substantially the entire surface of the second surface 32 and is exposed on the second surface 32. The reinforcing material 40 is also embedded in the inner and outer surfaces and the protruding end surface of the partition projection 65, and is also formed in the region on the inside of the partition projection 65 that faces the light source 62. This region becomes a circular light-transmitting region 66 in plan view, through which light from the light source 62 located directly behind is transmitted.

[0023] In this armrest 1A, when the light source 62 is energized and emits light, the emitted light passes through the light-transmitting region 66, causing the first surface 31 to emit light as indicated by the dotted arrow. At this time, the distance between the light source 62 and the light-transmitting region 66 is short, so light loss can be minimized. Therefore, by changing the thickness of the light-transmitting region 66, or by adding letters, pictures, or patterns to the light-transmitting region 66, it is possible to create shadows on the first surface 31 or make letters or pictures stand out. In particular, since the reinforcing material 40 is also embedded in the light-transmitting region 66, the amount of light transmitted to the light-transmitting region 66 changes as it passes through the reinforcing material 40, and shadows can be created even with the same light source 62.

[0024] In the armrest 1A of Embodiment 2, the reinforcing material 40 is embedded in the second surface 32 of the surface material 30A, so, similar to Embodiment 1, a simple structure can be used to improve the degree of freedom in adapting to the required mechanical strength. In particular, since the reinforcing material 40 is embedded in the second surface 32 which includes a light-transmitting region 66 facing the light source 62, the reinforcing material 40 can be used as a functional part that provides a decorative function. In particular, by appropriately selecting the mesh size of the nonwoven or woven fabric as the reinforcing material and the light-transmitting performance of the film, the design of the first surface 31 (brightness, shading, emphasis of patterns, etc.) by the light source 62 can be broadly set, improving the degree of freedom in adjusting light transmittance. The reinforcing material 40 may also be embedded in the partition protrusion 65. In this case, it will also reinforce the partition protrusion 65.

[0025] In the second embodiment, as shown in Figure 8, the reinforcing material 40 may not be provided in the light-transmitting region 66, but rather in the non-light-transmitting region 67 outside the light-transmitting region 66, which is outside the partition projection 65. By providing the reinforcing material 40 only in the non-light-transmitting region 67 in this way, the reinforcing material 40 can be given a shielding function that blocks light from the light source 62. Therefore, the light emission in the light-transmitting region 66 can be made more noticeable. Also, since the partition projection 65 is positioned at the boundary between the light-transmitting region 66 and the non-light-transmitting region 67, the reinforcing material 40 can be easily positioned in the non-light-transmitting region 67 using the partition projection 65 as a guide. The reinforcing material placed in the light-transmitting region 66 and the reinforcing material placed in the non-light-transmitting region 67 may be treated as different reinforcing materials with light-transmitting and light-shielding functions, respectively, separated by the partition projection 65. The reinforcing material embedded in the partition projection does not have to be embedded in the protruding end face of the partition projection, and may be embedded in only one of the inner or outer surfaces. The shape of the partition projection itself can also be changed as appropriate. The partition projection itself may be omitted.

[0026] A recess may be formed in the light-transmitting region, making it thinner than other regions. Providing a recess in the light-transmitting region increases the amount of light transmitted, making the light emission on the first surface more prominent. In this case, providing reinforcing material on the bottom and / or sides of the recess reinforces the light-transmitting region, which becomes thinner due to the formation of the recess. The reinforcing material may be provided not on the entire surface of the armrest, but only in a part of it. For example, reinforcing material may be provided only on the display operation area. Also, as shown in Figures 4 and 5, reinforcing material may be provided only on the first surface, or on both the first and second surfaces. The armrest itself can also be modified as appropriate. For example, the position and shape of the display operation area may differ from those in the above embodiment. There may be multiple display operation areas. The housing recess for the light source is not limited to a circular shape in plan view, but can be modified as appropriate to match the shape and size of the area to be illuminated. For example, the housing recess can be made into a rectangle or oval shape in plan view, or the housing recess can be formed in a straight line (groove shape) to arrange multiple light sources.

[0027] The following describes modifications to the present disclosure that are common to both Examples 1 and 2. The reinforcing material provided on the surface material is not limited to one type, but may be of multiple types. For example, in Example 1, a nonwoven fabric may be embedded in the region corresponding to the deformation-tolerant portion of the base material, and a second reinforcing material such as a woven fabric or film may be embedded in the other regions. By embedding a second reinforcing material of a different type from the first reinforcing material in a region outside the predetermined region, it becomes possible to select the reinforcing material according to the part to be reinforced and to provide appropriate reinforcement. In Example 2, a partition protrusion is provided as a protrusion to separate a light-transmitting region from a non-light-transmitting region. However, the protrusion of the present disclosure may be used, for example, as a pressing part for pressing a switch provided on the base material side, or as an engaging part (e.g., a fastening part) for engaging with an engaging part (e.g., a hole or recess) provided on a mating member such as the base material or another surface material. In this case as well, embedding a reinforcing material in the protrusion will reinforce the protrusion. This disclosure is applicable not only to seat components (center console, armrest) and door panels, but also to other interior components such as instrument panels.
