Description

  The present invention relates to an interior material. More specifically, the present invention relates to an interior material in a state in which an interior base material and a resin component separate from the interior base material are assembled.

  In recent years, interior materials used for vehicle interiors such as automobiles have been reduced in weight for improving fuel efficiency. From this point of view, as a base material (interior base material) constituting the interior material, for example, a laminated base material using a foaming material instead of an injection molding material has attracted attention. This interior base material is provided with a skin layer on the outer surface, and weight reduction is achieved by using a resin foam layer formed from a foam material as a core.

By the way, it is common to cut and use the laminated base material using the foamed material in a necessary size and shape, and the laminated state is exposed at the cut-out terminal portion. In consideration of using the base material cut out and used as the interior base material, some processing is required for the terminal portion in order to obtain the appearance as the interior material. Furthermore, an attachment part for attaching the interior base material to another separate part is required. That is, if it is the interior material shape | molded by the conventional injection molding, the attaching part could be integrally provided in interior material itself. However, the above base material is manufactured without an injection molding process or the like, and it is difficult to directly provide the mounting portion on the interior base material itself.
The following Patent Documents 1 and 2 are known as processing methods of the terminal portion for such a base material and techniques relating to attachment to other components.

JP 2004-217080 A JP 11-129754 A

Patent Document 1 (refer to Patent Document 1, see FIG. 4) discloses that terminal processing is performed by embedding a base terminal in a resin injected in a mold and integrating the resin into the terminal portion. It is a technology to do. According to this technology, although excellent terminal processing can be performed, there is a problem that advanced die technology is required, for example, by utilizing a difference in heat shrinkage between different materials.
Furthermore, a technique is known in which terminal processing is performed by covering the skin material from the outside to the inside in the terminal portion. However, this technique has a problem that the number of processes is very large and high processing accuracy is required because a narrow width of folding is required around the entire circumference. Furthermore, a separate bracket is required for fastening to other components, which increases the weight of the interior material.

  On the other hand, Patent Document 2 (refer to Patent Document 2, refer to a representative diagram) abuts a garnish having a fastening portion from the outside so as to cover the terminal portion of the door trim, and presses and fixes the terminal of the door trim by the garnish. Technology. This technique is an excellent technique in that it can be carried out with one resin part to be fastened to another part. However, in order to fix the terminal portion, the collar portion must be formed, and there is a problem that a terminal processing step requiring high processing accuracy is required in advance. Furthermore, it is difficult to form a collar portion small in a laminated base material using a foam material, and when it is formed small, it is difficult to sufficiently suppress and fix. Therefore, there is a problem that it is difficult to apply to a large area trim. Furthermore, when attaching the base material to another part, the base part of the base material is suppressed by a part of the separate part while pushing the clip of the separate part while bringing the base material into contact with the desired position of the other part. There is a problem that it requires complicated installation work.

  The present invention has been made in view of the above-described circumstances, and an interior material that can be easily and simultaneously subjected to terminal treatment and fastening to another component by using a separate resin component for the interior substrate. The purpose is to provide.

In order to solve the above problems, the interior material according to claim 1 is an interior material including an interior base material and a resin component assembled to the interior base material,
The resin component includes a fastening portion for fastening the resin component to another component, and a sandwiching portion that sandwiches both the front and back surfaces of the peripheral portion of the interior base material, and the peripheral edge of the interior base material It is summarized that it is attached along the part.

  The gist of the interior material according to claim 2 is that, in claim 1, the sandwiching portion has a shape that opens to the passenger compartment side.

  The gist of an interior material according to claim 3 is that, in claim 1 or 2, the fastening portion is arranged on the inner side of the peripheral edge portion of the interior substrate.

An interior material according to a fourth aspect of the present invention is the interior material according to any one of the first to third aspects, wherein the resin component includes a locking portion for locking a peripheral edge portion of the interior base material.
The locking portion serves as a retaining portion that holds the peripheral portion of the interior base material so that it does not come out of the clamping portion of the resin component in a state where the interior base material and the resin component are assembled. Is the gist.

The interior material according to claim 5 is the interior material according to any one of claims 1 to 4, wherein the interior base material includes a first skin layer, a resin foam layer, and a second skin layer in order.
The gist of the invention is that the resin component sandwiches both outer sides of the first skin layer and the second skin layer at the sandwiching portion.

  According to the interior material of the present invention, it is possible to more easily perform terminal treatment and fastening to another component at the same time using a separate resin component for a laminated interior substrate using a foam material. Furthermore, the terminal part of the interior base material can be hidden from the outside by sandwiching the terminal part of the interior base material with the resin part and arranging the terminal part in the resin part. Furthermore, since the resin part has a fastening part, only the resin part is required without requiring a part that bears only the fastening function to the other parts in the bracket, and without special processing on the interior base material side. Thus, the fastening can be performed. In addition, the terminal processing and fastening can be performed by one resin component.

  If the clamping part has a shape that opens to the passenger compartment side, the interior base material can be attached to the resin part from the passenger compartment side with resin parts already attached to other parts, or the interior base material can be resin The resin part with the interior base material can be attached to another part in a state where the part is attached in advance, and the mounting workability is excellent.

  When the fastening part is arranged inside the peripheral part of the interior base material, the fastening part can be covered with the interior base material, and the fastening part is arranged outside the peripheral part of the interior base material Compared to the above, it is not necessary to perform the appearance treatment associated with the fastening portion on the resin component itself. Furthermore, the resin component appearing on the surface on the side to be visually recognized can be formed small, and the appearance quality at the peripheral edge of the interior material can be improved.

  The resin part has a locking part for locking the peripheral part of the interior base material, and the peripheral part of the interior base material is resin while the locking part is assembled with the interior base material and the resin part. If it is a retaining part that keeps it from coming out from the part clamping part, the interior base material can be firmly attached to the resin part and workability when attaching these parts to other parts Excellent.

  When the interior base material includes a first skin layer, a resin foam layer, and a second skin layer in this order, and the resin component sandwiches both outer sides of the first skin layer and the second skin layer at the sandwiching portion, The attachment property between the material and the resin component can be further improved. That is, since the interior base material includes the resin foam layer in the center layer, the resin foam layer imparts good elasticity to the interior base material. Thereby, while the sandwiching portion sandwiches the interior base material, the interior base material can function to push the sandwiching portion apart, and a stronger mounting property can be obtained between them.

Among these, the interior material 1 of the present invention is suitable when the interior base material 10 including the first skin layer 101, the resin foam layer 102, and the second skin layer 103 in this order is used. When such an interior base material 10 provided with the resin foam layer 102 is used, good elasticity is imparted to the interior base material 10, whereas a clamping portion 22 described later sandwiches the interior base material 10. This is because the interior base material 10 functions so as to spread the sandwiching portion 22, and a stronger mounting property can be obtained between them.
The peripheral portion 104 of the interior base material 10 is a portion that is sandwiched between the sandwiching portions 22 and is a portion that is disposed along the periphery of the interior base material 10. The peripheral edge of the interior base material 10 includes an outer peripheral edge and an inner peripheral edge. The peripheral portion 104 will be described in detail together with the correlation with the resin component 20 in the description of the resin component 20 described later.

As long as the interior base material 10 includes the first skin layer 101, the resin foam layer 102, and the second skin layer 103 in this order, other structures, sizes, shapes, materials, and the like are not particularly limited.
The interior base material 10 has another layer interposed between one or both of the first skin layer 101 and the resin foam layer 102 and between the resin foam layer 102 and the second skin layer 103. You may prepare. That is, the interior base material 10 can be provided with other layers other than the first skin layer 101, the resin foam layer 102, and the second skin layer 103 as necessary, and is composed of only these three essential layers. Also good.

  Furthermore, each layer which comprises the interior base material 10 is a layer which comprises the interior base material 10 integrally. The interior base material 10 is formed by, for example, extruding a softened or melted resin that becomes the first skin layer 101, a resin that becomes the resin foam layer 102, and a resin that becomes the second skin layer 103 into a laminated state. And can be obtained by welding. The resin that becomes the resin foam layer 102 may be a foamed foamed resin, a resin that can be foamed later by including a foaming agent, or a resin in another state. Good.

  The “first skin layer (101)” is a layer that forms the outer surface of one surface of the interior base material 10. The first skin layer 101 may be made of any material, but is usually made of a thermoplastic resin. The kind of this thermoplastic resin is not specifically limited, For example, general purpose thermoplastic resins, such as polyolefin resin, polyester resin, and polyamide resin, can be used. Of these, polyolefin resins are preferred. Furthermore, as the polyolefin resin, polypropylene-based resins such as polypropylene homopolymer, ethylene-propylene random copolymer, ethylene-propylene block copolymer, high pressure method low density polyethylene, medium low pressure method low density polyethylene, high density polyethylene, etc. And polyethylene-based resins. Among these, a polypropylene resin is preferable.

  The “resin foam layer (102)” is a layer located between the first skin layer 101 and the second skin layer 103. As the resin foam layer 102, a foamed resin obtained by foaming a thermoplastic resin can be used. The foamed resin is preferably made of a crosslinked resin in order to be lightweight and have sufficient strength.

  The kind of thermoplastic resin which comprises the resin foam layer 102 is not specifically limited, For example, the various materials illustrated in the 1st skin layer 101 can be used. The thermoplastic resin constituting the resin foam layer 102 may be the same as or different from the thermoplastic resin constituting the first skin layer 101, and the thermoplastic resin constituting the second skin layer 103. It may be the same as or different from, but is preferably the same. That is, it is preferable to use a polypropylene resin.

Also, the type of foaming agent used to form the resin foam layer 102 is not particularly limited, and for example, a pyrolytic chemical foaming agent that decomposes by heating to generate gas can be used. Either a foaming agent or an inorganic pyrolytic foaming agent may be used.
Further, as described above, a crosslinking agent can be used to obtain a crosslinked resin. The strength and heat resistance of the resin foam layer 102 can be improved by blending a crosslinking agent and introducing a crosslinked structure together with foaming.

  The expansion ratio in the resin foam layer 102 as described above is not particularly limited, but is preferably 2 to 10 times, particularly 2 to 8 times, and more preferably 3 to 7 times. The cell diameter is preferably 0.1 to 500 μm, particularly preferably 5 to 400 μm, and more preferably 10 to 300 μm.

The “second skin layer (103)” is a layer that forms the outer surface of the other surface of the interior base material 10. Similar to the first skin layer 101, the second skin layer 103 may be made of any material, and is usually made of a thermoplastic resin. The kind of the thermoplastic resin is not particularly limited, and the same thermoplastic resin as exemplified in the first skin layer 101 can be exemplified, and among these, a polypropylene resin is preferable.
However, when the second skin layer 103 is made of a thermoplastic resin, the thermoplastic resin constituting the first skin layer 101 and the thermoplastic resin constituting the second skin layer 103 may be the same, May be different. Further, it may be the same as or different from the thermoplastic resin constituting the resin foam layer 102, but is preferably the same. That is, it is preferable to use a polypropylene resin for any layer.

  The thermoplastic resin constituting the first skin layer 101 and the second skin layer 103 includes a filler, a colorant, an antioxidant, an ultraviolet absorber, an antistatic agent, a flame retardant, a flame retardant aid, and an antibacterial agent. Further, a deodorizing agent, a softening agent and the like can be blended. These may use only 1 type and may use 2 or more types together. Among these, although the kind of filler is not particularly limited, an inorganic filler is preferable, and examples thereof include inorganic particles such as talc, clay, silica, and calcium carbonate, and inorganic fibers such as glass fiber and carbon fiber. By blending these fillers, the strength and rigidity of each skin layer can be improved, whereby the strength and rigidity of the interior base material 10 can be improved.

  Furthermore, each layer which comprises the interior base material 10 normally comprises the interior base material 10 integrally. In particular, the base material is preferably a base material in which the respective layers are fused without using an adhesive or the like between the respective layers. The interior base material 10 is formed by, for example, extruding a softened or melted resin that becomes the first skin layer 101, a resin that becomes the resin foam layer 102, and a resin that becomes the second skin layer 103 into a laminated state. And can be obtained by welding.

  More specifically, (1) when the interior base material 10 includes only the essential three layers of the first skin layer 101, the resin foam layer 102, and the second skin layer 103, it is supplied at a predetermined speed, A molten resin sheet to be the first skin layer 101 extruded from a T die attached to an extrusion molding machine is laminated on one surface of the resin foam sheet to be the traveling resin foam layer 102, and then inserted between the cooling rolls. Then, the resin foam sheet to which the resin sheet to be the first skin layer 101 is bonded is supplied at a predetermined speed and traveled, and the other surface of the resin foam sheet is extruded. A molten resin sheet to be the second skin layer 103 extruded from a T die attached to the molding machine is laminated, and then cooled and joined by means such as inserting between cooling rolls. Accordingly, it is possible to obtain an interior base material 10. Further, (2) the foamed resin sheet and the resin sheet to be each skin layer are formed by forming each sheet into a sheet shape, and then heating and welding the laminated surfaces of the respective sheets to heat the interior base material 10. You can also get In any of the above methods (1) and (2), the resin sheet to be the resin foam layer 102 may be foamed and can be foamed later by including a foaming agent. It may be.

When the interior material 1 of the present embodiment is adopted for an automotive interior material, any one of the first skin layer 101 and the second skin layer 103 among the interior base material 10 is disposed on the vehicle interior side, Any layer may be disposed outside the vehicle. Further, of the first skin layer 101 and the second skin layer 103, any one of the skin layers arranged on the vehicle interior side can form a design surface on the vehicle interior side. In the case of forming a design surface, the surface of the skin layer can have a pattern. Examples of this pattern include a wrinkle pattern.
1 to 6 exemplarily illustrate that the first skin layer 101 is disposed on the vehicle exterior side and the second skin layer 103 is disposed on the vehicle compartment side.

  The thickness of the interior base material 10 as described above is not particularly limited as long as it has sufficient strength and rigidity and a predetermined shape is maintained. For example, in the case of the interior base material 10 having only three essential layers. The overall thickness can be 2.5 to 10.0 mm, preferably 3.0 to 6.0 mm, particularly preferably 3.5 to 5.0 mm. The thickness of each of the first skin layer 101, the resin foam layer 102, and the second skin layer 103 is not particularly limited, but the resin foam layer 102 has a thickness of 1.5 to 8.0 mm, particularly 2.5 to 4.5 mm. Further, 3.0 to 4.0 mm is preferable. The thicknesses of the first skin layer 101 and the second skin layer 103 are preferably 100 to 400 μm, particularly 120 to 380 μm, and more preferably 150 to 350 μm.

The thickness ratio between the resin foam layer 102 and each of the first skin layer 101 and the second skin layer 103 is not particularly limited, but the thickness (t ₂ ) of the resin foam layer 102 and the thickness of the first skin layer 101 are not limited. The ratio [(t ₂ / t ₁ ) and (t ₂ / t ₃ )] to the thickness (t ₁ ) and the thickness (t ₃ ) of the second skin layer 103 is 5 to 25, particularly 8 to 22, 12-18 are preferable. When (t ₂ / t ₁ ) and (t ₂ / t ₃ ) are 5 to 25, the interior base material 10 having sufficient strength and rigidity and having a predetermined shape can be obtained.

Further, the thicknesses of the first skin layer 101 and the second skin layer 103 may be the same or different, but it is preferable that there is no great difference, and (t ₁ / t ₃ ) is 0.7 to 1 .3, particularly 0.8 to 1.2, more preferably 0.9 to 1.1, more preferably the same.

  On the other hand, the “resin part 20” includes a fastening part 21 for fastening the resin part 20 to the other part 40 and a clamping part 22 for clamping the peripheral edge part 104 of the interior base material 10. Further, the resin component 20 is attached along the periphery of the interior base material 10 (see FIGS. 1 and 2).

  The resin component 20 may be made of any resin, but is usually a thermoplastic resin. The kind of this thermoplastic resin is not specifically limited, For example, general purpose thermoplastic resins, such as polyolefin resin, polyester resin, and polyamide resin, can be used. Of these, polyolefin resins are preferred. When the clamping part 22 is formed, it has excellent flexibility and bending resistance, and can hold the peripheral edge part 104 of the interior base material 10 more firmly. Furthermore, it is excellent in that flexibility can be imparted to the fastening portion 21 and the height adjusting portion 29. Further, as will be described later, the locking portion 23 is formed by partially reducing the thickness, so-called permanent. It is also particularly suitable for hinges of the form called hinges or integral hinges.

  When the interior material 1 of the present invention is used as an interior material for an automobile, the other component 40 may be a body panel of an automobile. In addition, the other component 40 is exemplified by another automotive interior material that can have a mounting relationship with the automotive interior material.

The “fastening portion (21)” is a part used for fastening the resin component 20 to the other component 40. The form of this fastening part 21 is not specifically limited, For example, (1) As illustrated in FIG. 1 and FIG. 2 etc., it can have the fastening part 21 as a plate-like part which has a fastening hole. In this case, a separate fastening clip 30 (see FIG. 1) is used, the fastening clip 21 is inserted into the through hole 211 of the fastening portion 21, and fastened to the body panel of the other component 40 from the vehicle compartment side. Can do. In addition, as this fastening clip 30, the thing of any conventionally well-known form can be utilized.
Further, (2) as illustrated in FIG. 9, the fastening clip portion 212 itself may have the fastening clip portion 212. In this case, the resin component 20 can be fastened to the other component 40 only by the fastening portion 21.
These forms of (1) and (2) can be used together in one interior material 1.

Moreover, although the fastening part 21 can also be arrange | positioned outside the peripheral part 104 of the interior base material 10, as illustrated in FIG.1 and FIG.7 etc., it is an inner side rather than the peripheral part 104 of the interior base material 10. FIG. It is preferable to arrange | position.
The fact that the fastening portion 21 is arranged on the inner side of the peripheral edge portion 104 of the interior base material 10 will be described below with reference to FIGS. 1 and 7. 1 corresponds to the XX section in FIG. 7 (however, for the sake of clarity of FIG. 1, the fastening clip 30 and other parts 40 are shown in FIG. 1, but these are shown in FIG. Is not shown). And the inside is a side corresponding to the space A, and the space hidden inside by covering the interior base material 10 is the inside. On the other hand, the outer side is the side corresponding to the space B, the second skin layer 103 side of the interior base material 10, and the side that becomes the design surface in the interior material for automobiles. As described above, the fastening portion 21 is disposed on the inner side (space A), so that the fastening portion 21 can be processed without being exposed to the design surface side, and the fastening portion 21 is made of the interior base material 10. Therefore, there is no need for any other configuration for hiding the fastening portion 21 from the design surface side.

  Although the said "clamping part (22)" should just be a form which can clamp the interior base material 10, for example, it has the cross section opened by the U shape as illustrated by FIGS. It can be in the form. The U-shaped sandwiching portion 22 is preferably opened toward the passenger compartment side in an automobile interior material. Then, by inserting the peripheral edge portion 104 of the interior base material 10 into this opening, the peripheral edge portion 104 is sandwiched and fixed by the sandwiching portion 22.

  Furthermore, the clamping part 22 usually has two clamping plate parts 221, and the two clamping plate parts 221 sandwich both the front surface 10 a and the back surface 10 b of the peripheral edge 104. Furthermore, in the interior material for automobiles, among the sandwiching plate portions 221, the design plate side (front surface 10a side) sandwiching plate portion 221a and the non-design surface side (rear surface 10b side) sandwiching plate portion 221b. Have. As illustrated in FIG. 1 and the like, in the interior base material 10 that includes the first skin layer 101, the resin foam layer 102, and the second skin layer 103 in this order, the sandwiching plate portion 221a on the design surface side is the first. The inner base material 10 and the resin component 20 are assembled by abutting the two skin layers 103, the non-design surface side sandwiching plate portion 221b contacting the first skin layer 101, and sandwiching the peripheral edge portion 104. .

  Since the sandwiching plate portion 221 a on the design surface side (surface 10 a side) may be exposed on the vehicle compartment side, the design can be applied to the surface in the same manner as the second skin layer 103. Furthermore, the shape can be tapered toward the front end (usually the passenger compartment side) so that the boundary with the second skin layer 103 is hardly visible (see FIG. 1 and the like). On the other hand, the non-design surface side (rear surface 10b side) sandwiching plate portion 221b is U-shaped by warping in the direction away from the sandwiching plate portion 221a as illustrated in FIG. It can be set as the form where the shape opening becomes large. By setting it as such a form, when assembling the interior base material 10 to the resin component 20, the peripheral part 104 can be more easily inserted in the clamping part 22. FIG.

  The insertion depth (length L in FIG. 9) of the peripheral edge 104 in the sandwiching portion 22 is not particularly limited, but can be 5 to 30 mm, and particularly 10 to 20 mm. The insertion depth refers to the inner length of the sandwiching plate portion 221 on the shorter side when the sandwiching portion 22 having a U-shape has the sandwiching plate portion 221 having a different length. is there.

  Furthermore, in the clamping part 22, while forming the width | variety of a U-shaped opening part narrower than the thickness of the interior base material 10, and forming the width | variety of the bottom part in a U-shape wider, The peripheral edge portion 104 can be firmly held by the two holding plate portions 221. Moreover, after forming the U-shaped inner width larger than that of the interior base material 10, the peripheral portion 104 is provided in the U-shape by providing irregularities that are caught on the surface of each skin layer of the interior base material 10. Can be more firmly held by the sandwiching portion 22.

  Moreover, the resin component 20 can be provided with the height adjustment part 29 so that it may be illustrated by FIG. The height adjusting portion 29 is a portion for balancing the height with the fastening portion 21 and is a portion capable of improving the appearance of the resin component 20 from the passenger compartment side. Further, by increasing the height of the height adjusting portion 29, the fastening portion 21 can be operated to be pressed against the other component 40 side, and the fastening portion 21 can be functioned more firmly.

  The resin component 20 is attached along the periphery of the interior base material 10 as described above. Attaching along the peripheral edge means attaching in a shape along at least a part of the peripheral edge of the interior base material 10, for example, as illustrated in FIG. The state where the resin component 20 is attached along the periphery of 10 is mentioned. Furthermore, it can also be attached along the inner periphery. Examples of the inner periphery include an inner periphery in an ornamental through hole, an armrest through hole, a speaker grill through hole, an inside handle bezel through hole, and the like formed in the interior base material 10.

Furthermore, FIG. 7 (exemplifies the resin component 20 in a door trim as an automobile interior material) sandwiches the entire circumference of the interior substrate 10 shown in FIG. 8 (illustrates the interior substrate 10 in a door trim as an automobile interior material). This is a resin part 20 in a form that can be formed. Thus, the resin component 20 can also be assembled along the entire circumference of the interior base material 10.

Then, when the peripheral edge portion 104 of the interior base material 10 is inserted into the clamping portion 22 (the operation of the dotted line Y5 is performed) and reaches the fixed claw 236 of the resin component 20, the fixed claw 236 causes the insertion portion 105 of the interior base material 10 to be inserted. Both insertion claws 105a and 105b are slightly pushed inwardly (the operation of dotted line Y6 is performed), and the insertion portion 105 is inserted between the fixed claws 236. By closing at the engagement missing portion 109 formed at the rear end, the insertion portion 105 and the fixing claw 236 are engaged, and the interior base material 10 is locked by the resin component 20.

By adopting the configuration of the present invention, the following effects can be obtained. That is, it is possible to more easily perform the terminal processing and the fastening to the other component 40 at the same time by using the resin component 20 for the interior base material 10.
Furthermore, the terminal part (namely, peripheral edge part 104) of the interior base material 10 is clamped by the resin component 20, and the terminal part of the interior base material 10 is hidden from the outside by disposing the terminal part in the resin part. The processing of the terminal unit itself can be unnecessary or simplified.
Furthermore, since the resin component 20 includes the fastening portion 21, there is no need for a component that bears only the fastening function to the other component 40 in the bracket. Therefore, the number of parts can be reduced without requiring the number of fastening portions of the bracket. Further, the fastening can be performed only by the resin component 20 without requiring any special processing on the interior base material 10 side.
