Description

  The present invention relates to a vehicle interior material.

  Conventionally, an interior material for a vehicle in which a base material, a foamed resin layer, and a skin material are integrally formed is known (Patent Document 1 below). The vehicle interior material described in Patent Document 1 has a configuration in which a foamed resin layer is molded by injecting a foamable resin material onto the back surface of the skin material after the skin material is molded. Moreover, the skin material of patent document 1 is comprised by a pair of skin piece being sewn.

JP 04-105910 A

  By the way, as a manufacturing method of a vehicle interior material in which a base material, a foamed resin layer, and a skin material are integrally formed, both the skin material and the base material molded into a predetermined product shape are overlapped. A method for injecting a foamable resin material into a space formed between members is also known. Thereby, since a foamed resin layer can be interposed between a base material and a skin material, the operation | work which sticks a skin material on the surface of a foamed resin layer can be reduced.

  In such a manufacturing method, it is necessary to prevent the foaming resin material from leaking to the outside from between the skin material and the base material. For this reason, a method of injecting the foamable resin material in a state in which the peripheral end portion of the skin material is folded back to the inside of the vehicle interior material and brought into contact with the base material is known. This prevents the peripheral edge of the skin material from being pressed against the base material by the internal pressure when the foamable resin material is foamed, resulting in a gap between the peripheral edge of the skin material and the base material. It is possible to prevent the foamable resin material from leaking to the outside (so-called self-sealing structure).

  Here, in the skin material in which a pair of skin pieces as in Patent Document 1 are sewn, a groove portion is formed along the sewing line. Thereby, in the formation part of a groove part, since the flatness of a surface cannot be ensured, a clearance gap will arise between a skin material and a base material. As a result, there is a concern that the foamable resin material leaks outside through the gap (that is, in the groove). For this reason, in the skin material by which a pair of skin pieces were sewn, there existed a problem that the shaping | molding method using the said self-seal structure was not applicable.

  The present invention has been completed based on the above circumstances, and even when a skin material having a pair of skin pieces sewn together is used, foaming is performed between the base material and the skin material. An object of the present invention is to provide a vehicle interior material that can be molded by a method of injecting a functional resin material.

  In order to solve the above-mentioned problems, an interior material for a vehicle according to the present invention includes a base material, a foamed resin layer disposed so as to cover the surface of the base material, and a skin disposed so as to cover the foamed resin layer. Vehicle interior material formed integrally with a material, wherein the skin material has at least a pair of skin pieces, the surfaces of the pair of skin pieces are overlapped with each other, and ends thereof After sewing together in an aligned state, the pair of skin pieces has a shape that is widened by opening them in opposite directions, and has a groove formed by each of the surfaces of the pair of skin pieces, and The skin material includes a skin material body portion covering the surface of the foamed resin layer, and a skin material circumferential edge portion folded back with respect to the skin material body portion so as to cover a circumferential edge portion on the back surface of the foam resin layer. And the skin material peripheral edge is the base Between the surface of the foamed resin layer and the peripheral end of the foamed resin layer, and is in contact with the surface of the base material. It is arranged in a shape that is recessed in a direction away from the material, and a porous soft material is arranged in a shape that fills a gap formed between the inner surface of the groove and the surface of the substrate. Have.

  The vehicle interior material of the present invention is molded as follows. First, after forming the skin material into a predetermined shape in the molding die, the skin material and the base material are arranged in an overlapping manner. At this time, the peripheral edge portion of the skin material is brought into contact with the surface of the base material. Then, the foamed resin material in a molten state is injected into a space (foamed resin layer molding space) generated between the skin material and the base material. Thereafter, the foamed resin material is foamed and cooled to form the foamed resin layer. As a result, the base material, the foamed resin layer, and the skin material are integrally molded.

  Here, when the foamable resin material foams in the foamed resin layer molding space, the pressure in the foamed resin layer molding space increases. With this pressure (foaming pressure), the peripheral edge of the skin material is pressed against the surface of the substrate (self-sealing structure). Thereby, the situation which a clearance gap produces between a skin material peripheral edge part and the surface of a base material can be suppressed, and a foaming resin material does not leak out of the foaming resin layer shaping | molding space from the said clearance gap.

  In the present invention, the skin material is formed by sewing a pair of skin pieces. Thereby, the groove part is formed along the sewing line of a pair of skin piece in a skin material. For this reason, in the formation part of a groove part, there exists a concern about the situation which a clearance gap produces between a skin material peripheral edge part and the surface of a base material. However, in the present invention, the porous soft material is disposed so as to fill a gap formed between the inner surface of the groove and the surface of the substrate.

  As a result, when the foamed resin layer is molded, the foamable resin material constituting the foamed resin layer is blocked from flowing to the outside by the soft material in the groove portion, and the situation of leaking to the outside is suppressed. More precisely, a part of the foamable resin material soaks into the porous soft material, and the flow stops inside. Moreover, since the soft material is porous, when the foamable resin material is foamed, the air in the foamed resin layer molding space can pass through the inside of the soft material and exit to the outside. Thereby, the situation where a void (bubble) generate | occur | produces in the foamed resin layer after shaping | molding can be suppressed.

  From the above, in the present invention, when the foamed resin layer is injection-molded by using the skin material formed by sewing a pair of skin pieces, the situation where the foamable resin material leaks to the outside is prevented. it can. In other words, the vehicle interior material of the present invention can be molded by a method of injecting a foamable resin material between the base material and the skin material.

  In the above-described configuration, the soft material includes a fitted member to be fitted into the groove, and a covering member arranged to cover the fitted member and cover the opening of the groove. can do.

  In the present invention, the member to be fitted is fitted into the groove, and the opening of the groove is covered with the covering member. Thereby, while being able to close the groove part in a skin material peripheral edge part with a to-be-fitted member, the flatness of the surface of a skin material peripheral edge part can be ensured with a coating | coated member. As a result, it is possible to more reliably suppress the occurrence of a gap between the skin material peripheral end and the base material.

  According to the present invention, even when a skin material having a pair of skin pieces sewn together is used, it is possible to mold by a method in which a foamable resin material is injected between the base material and the skin material. A vehicle interior material can be provided.

  An embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a perspective view of a glove box 10 (more precisely, a lid portion of the glove box) that is the vehicle interior material of the present embodiment, as viewed from the back side. The glove box 10 is provided on an instrument panel (not shown) in the vehicle, and has a substantially square shape in plan view as shown in FIG.

  As shown in FIG. 2, the glove box 10 includes a base material 20, a foamed resin layer 30 arranged to cover the surface 20 </ b> A of the base material 20, and a skin material 40 arranged to cover the foamed resin layer 30. And are integrally formed. In FIG. 2, a part of the glove box 10 is shown in a sectional view.

  The base material 20 is made of a synthetic resin material such as polypropylene, for example. The base material 20 has a square shape in plan view, and the peripheral end portion (peripheral four sides) is a step portion 21 that is low in the direction away from the skin material 40 (see FIG. 2). The step portion 21 has a configuration in which a peripheral end portion of the skin material 40 (a skin material peripheral end portion 42, which will be described in detail later) is arranged (see FIG. 9). In other words, the base material 20 has a convex shape whose central portion protrudes toward the foamed resin layer 30 side.

  The foamed resin layer 30 is, for example, urethane foam. The center portion of the foamed resin layer 30 is a concave portion 31 that is recessed corresponding to the convex shape of the base material 20, and the central portion of the base material 20 is fitted into the concave portion 31. The foamed resin layer 30 injects the foamable resin material into the space (foamed resin layer molding space S1) between the skin material 40 and the base material 20 in a state where the skin material 40 and the base material 20 are stacked. It is formed by foaming (details will be described later).

  The skin material 40 is made of, for example, animal skin (genuine leather) such as cowhide, and is formed by sewing a pair of skin pieces 45 and 46 as shown in FIG. In addition, the skin material 40 should just be formed by sewing at least 2 or more skin pieces, for example, may be formed by sewing 3 or more skin pieces.

  As shown in FIG. 4, the pair of skin pieces 45 and 46 are sewn by stitching them together with a sewing thread 47 in a state where their ends are aligned, after the surfaces (design surfaces) are overlapped. Then, as shown in FIG. 4, the pair of stitched skin pieces 45 and 46 are opened and spread in opposite directions.

  Thereby, the part enclosed by both surfaces of a pair of skin pieces 45 and 46 is made into the groove part 50 which makes a substantially V shape. That is, this groove part 50 is formed by the mutually opposing surface in a pair of skin pieces 45 and 46, and shall extend along the sewing line of a pair of skin pieces 45 and 46. FIG.

  In addition, as shown in FIG. 11, the groove 50 has a shape that is recessed inside the glove box 10. Note that, for example, a hot melt tape 70 is attached to the overlapping portion (sewing allowance) of the pair of skin pieces 45 and 46, and the hole formed by the sewing thread 47 between the pair of skin pieces 45 and 46 is closed. It has become. The hot melt tape 70 is illustrated only in FIG. 11, and is not illustrated in FIG.

  As shown in FIG. 2, the skin material 40 includes a skin material body portion 41 that covers the surface of the foamed resin layer 30 (design surface side, vehicle interior side in the glove box 10), and a peripheral end portion of the skin material body portion 41. The skin material side portion 43 that extends and covers the side surface of the foamed resin layer 30 and the skin material body portion 41 that extends from the peripheral end portion of the skin material side surface portion 43 and covers the peripheral end portion 32 on the back surface of the foamed resin layer 30. And a skin material peripheral end portion 42 that is folded back.

  In other words, the skin material peripheral end portion 42 is folded back such that the tip thereof faces the inside of the glove box 10. As shown in FIG. 9, the skin material peripheral end portion 42 is sandwiched between the surface 20 </ b> A of the base material 20 (the peripheral end portion of the base material 20 and the bottom surface of the stepped portion 21) and the peripheral end portion 32 of the foamed resin layer 30. And is in contact with the surface 20A of the substrate 20.

  Further, as shown in FIG. 2, the skin material peripheral end portion 42 is formed so as to extend over the entire circumference of the skin material 40 having a planar view shape. Thereby, the skin material 40 becomes a structure which contacts the peripheral edge part of the base material 20 over the perimeter of the peripheral edge part. Thereby, when the foamable resin material constituting the foamed resin layer 30 is injected between the skin material 40 and the base material 20 (foamed resin layer molding space S1) when the glove box 10 is molded, The foamable resin material does not leak to the outside (details will be described later).

  The groove part 50 mentioned above is formed in the form extended over the skin material main-body part 41, the skin material peripheral edge part 42, and the skin material side part 43, for example, and is distribute | arranged in the form protruded to the foamed resin layer 30 side. Here, in the skin material circumferential end portion 42, as shown in FIGS. 3 and 11, the groove portion 50 is arranged in a shape recessed in a direction away from the base material 20. For this reason, a gap is formed between the inner surface 50 </ b> A of the groove 50 and the surface 20 </ b> A of the base material 20 (the surface on the side covered with the skin material 40 in the base material 20). In the present embodiment, as shown in FIG. 11, the gap formed between the inner surface 50 </ b> A of the groove portion 50 (a part of each surface of the pair of skin pieces 45 and 46) and the surface 20 </ b> A of the base material 20 is filled. A soft material 52 is disposed as a sealing member.

  The soft material 52 is porous and has air permeability. As shown in FIG. 11, the soft material 52 includes a fitted member 53 fitted into the groove portion 50 and a covering member 54 arranged to cover the fitted member 53. The fitted member 53 is, for example, a porous soft resin material (for example, a foamed slab urethane). As shown in FIG. 10, the fitted member 53 has a long shape along the extending direction of the groove 50, and in a natural state (a state before being covered with the covering member 54), as shown in FIG. 5. In addition, it has a rectangular parallelepiped shape.

  The covering member 54 is, for example, a porous nonwoven fabric having a sheet shape. As shown in FIG. 11, the member 53 to be fitted is disposed in the groove portion 50 so as to be covered with the covering member 54 so as to be crushed by the inner surface of the covering member 54 and the groove portion 50. Thus, the fitted member 53 has a substantially triangular shape in cross-section in the groove portion 50 following the shape of the groove portion 50, and is in close contact with the inner surface 50 </ b> A of the groove portion 50.

  More specifically, the two side surfaces 53A of the fitted member 53 are arranged in contact with the inner surface 50A of the groove portion 50 (part of each surface of the pair of skin pieces 45 and 46) without any gaps. . Further, the side surface 53A of the fitted member 53 is bonded to the inner surface 50A of the groove portion 50 via an adhesive. Note that a configuration in which at least one of the two side surfaces 53A of the fitted member 53 is bonded to the inner surface 50A of the groove 50 may be employed.

  As shown in FIGS. 5 and 6, the covering member 54 is attached to both the pair of skin pieces 45 and 46 so as to cover the opening of the groove portion 50. Specifically, as shown in FIG. 10, the covering member 54 includes a first covering portion 56 that covers the opening of the groove portion 50 from the base material 20 side (upper side of FIG. 10), and the foamed resin layer 30 that covers the opening of the groove portion 50. And a second covering portion 58 that covers from the side (left side in FIG. 10). In addition, as shown in FIG. 10, the terminal part (part other than the 1st coating part 56 and the 2nd coating part 58) of the coating | coated member 54 is the back surface (lower surface in FIG. 10) in the skin material peripheral edge part 42. As shown in FIG. Is pasted.

  As shown in FIGS. 6 and 11, the first covering portion 56 is affixed so that the surface thereof is substantially flush with the surfaces of the pair of skin pieces 45 and 46. Thus, by covering the groove part 50 with the first covering part 56, the flatness of the surface of the skin material 40 and the surface of the first covering part 56 can be maintained. As a result, it is possible to more reliably prevent the occurrence of a gap between the base material 20 and the skin material 40 and between the base material 20 and the first covering portion 56 (see FIG. 11).

  The 2nd coating | coated part 58 is distribute | arranged in the form interposed between the groove part 50 and the foamed resin layer 30. As shown in FIG. In addition, in FIG. 11, the 2nd coating | coated part 58 of the state before the foamed resin layer 30 is formed is illustrated with the dashed-two dotted line.

  Further, as shown in FIG. 10, the length of the fitted member 53 in the longitudinal direction (left and right direction in FIG. 10) is, for example, such that the fitted member 53 is completely covered by the peripheral end portion of the base material 20. It is preferable that the length is set. Thereby, since the to-be-fitted member 53 is concealed by the base material 20 and it can prevent that the to-be-fitted member 53 is visually recognized, design property can be made higher. The length and shape of the fitted member 53 can be changed as appropriate.

  Next, the mold 60 for manufacturing the glove box 10 will be described. As shown in FIG. 7, the mold 60 in the present embodiment includes a pair of molds (an upper mold 61 and a lower mold 65) and a slide mold 68 that is slidably attached to the lower mold 65. Yes.

  A surface 65A of the lower die 65 facing the upper die 61 is a molding surface for molding the skin material 40 into a predetermined shape. A plurality of suction holes 66 are formed in the facing surface 65A, and a vacuum suction device (not shown) such as a vacuum pump is connected to each suction hole 66.

  Thereby, it becomes the structure which can give a negative pressure with respect to the skin material 40 via each suction hole 66 by operating a decompression suction device in the state which set the skin material 40 to the lower mold | type 65. Yes. Thereby, the skin material 40 can be attracted | sucked to the opposing surface 65A in the lower mold | type 65 by attracting | sucking the skin material 40, and it can shape | mold the skin material 40 in the predetermined shape which followed the shape of 65 A of opposing surfaces. Yes (evacuation).

  A surface 61 </ b> A of the upper mold 61 facing the lower mold 65 is a shape corresponding to the back surface shape of the base material 20. A suction device 62 capable of sucking the base material 20 is installed inside the upper mold 61. For example, the suction device 62 is configured to generate a negative pressure by the Venturi effect. By operating the suction device 62, the base material 20 can be sucked and fixed to the facing surface 61A.

  The upper mold 61 is a movable mold that can approach or separate from the lower mold 65 (fixed mold) by a driving device (not shown) (for example, an electric motor, an air cylinder, a hydraulic cylinder, or the like). The upper mold 61 can be closed with the lower mold 65 approached, and the mold can be opened with the upper mold 61 spaced apart.

  The slide die 68 (nested type) is for holding the shape of the skin material peripheral end portion 42 of the skin material 40 (the shape folded back inside), and the tip of the slide die 68 is the skin material peripheral end portion 42. The base end side is covered from above. The slide mold 68 is attached to the lower mold 65 and is configured to be slidable in a direction perpendicular to the moving direction of the upper mold 61 relative to the lower mold 65.

  When the upper mold 61 and the lower mold 65 are closed with the base material 20 disposed on the upper mold 61 and the skin material 40 disposed on the lower mold 65, as shown in FIG. The part 21) and the skin material peripheral edge part 42 are configured to overlap over the entire circumference. Thereby, the closed space (foamed resin layer molding space S1) is formed between the skin material 40 and the base material 20. In this foamed resin layer molding space S1, a foamable resin material can be injected from an injection device (not shown) provided in the mold 60.

  Next, a method for manufacturing the glove box 10 using the mold 60 will be described. First, as shown in FIG. 7, with the upper mold 61 and the lower mold 65 being opened, the skin material 40 with the soft material 52 attached to the lower mold 65 is disposed. The material 20 is arranged. Then, by operating the lower vacuum suction device, the skin material 40 is formed into a predetermined product shape (a shape following the facing surface 65A) having the skin material peripheral end portion 42 (vacuum forming step).

  In addition, the base material 20 is shape | molded by the predetermined | prescribed product shape in the process before arrange | positioning to the upper mold | type 61. FIG. Further, the surface 20A of the substrate 20 may be subjected to a surface treatment such as a flame treatment in advance so that the adhesive force with the foamed resin layer 30 is increased.

  Next, as shown in FIG. 8, the upper mold 61 and the lower mold 65 are closed (mold closing process). Thereby, the skin material peripheral edge part 42 and the peripheral edge part (step part 21) of the base material 20 contact. In addition, in the formation part of the groove part 50, the skin material peripheral edge part 42 and the base material 20 contact via the soft material 52. FIG. Thereby, a foamed resin layer molding space S <b> 1 that is a closed space is formed between the skin material 40 and the base material 20.

  Next, a foamable resin material (for example, a urethane resin added with a foaming agent) in a molten state is injected into a foamed resin layer molding space S1 from an injection device (not shown) and filled (foamed resin layer molding step). . At this time, when the injected foamable resin material is foamed in the foamed resin layer molding space S1, the skin material peripheral end portion 42 is pressed against the base material 20 side (upper side in FIG. 9) by this foaming pressure. Thereby, the situation which a clearance gap produces between the skin material peripheral edge part 42 and the surface 20A of the base material 20 can be suppressed, and foamable resin material does not leak out of the foaming resin layer molding space S1 from the clearance gap ( Self-sealing structure).

  Then, the foamed resin layer 30 is formed by cooling the injected foamable resin material, and the foamed resin layer 30 is joined to the skin material 40 and the base material 20. Thereby, the glove box 10 with which the skin material 40, the foamed resin layer 30, and the base material 20 were integrated is shape | molded. After the foamed resin layer 30 is cooled, the glove box 10 can be taken out by opening the upper mold 61 and the lower mold 65 and sliding the slide mold 68 in a direction away from the upper mold 61 and the lower mold 65.

  Next, the effect of this embodiment will be described. In the glove box 10 of the present embodiment, the base material 20, the foamed resin layer 30 disposed so as to cover the surface 20 </ b> A of the base material 20, and the skin material 40 disposed so as to cover the foamed resin layer 30 are integrated. The skin material 40 has at least a pair of skin pieces 45 and 46, the surfaces of the pair of skin pieces 45 and 46 are overlapped with each other, and the end portions thereof are formed. After the stitches are aligned, the pair of skin pieces 45, 46 are opened in opposite directions and spread to form a groove 50 formed by each of the surfaces of the pair of skin pieces 45, 46. Furthermore, the skin material 40 is folded back with respect to the skin material body 41 so as to cover the skin material body 41 covering the surface of the foamed resin layer 30 and the peripheral end 32 on the back surface of the foamed resin layer 30. A skin material peripheral end portion 42, and the skin material peripheral end portion 42 is sandwiched between the surface 20 A of the base material 20 and the peripheral end portion 32 of the foamed resin layer 30, and with respect to the surface 20 A of the base material 20. In contact with each other, the skin material peripheral end portion 42 is arranged so that at least a part of the groove portion 50 is recessed in a direction away from the base material 20, and between the inner surface 50 </ b> A of the groove portion 50 and the surface 20 </ b> A of the base material 20. It is characterized in that a porous soft material 52 is disposed so as to fill a gap formed in the structure.

  In the present embodiment, the skin material 40 is formed by sewing a pair of skin pieces 45 and 46. Thereby, the groove part 50 is formed along the sewing line of a pair of skin pieces 45 and 46 in the skin material 40. For this reason, in the formation part of the groove part 50, there exists a concern about the situation where a clearance gap produces between the skin material peripheral edge part 42 and the surface 20A of the base material 20. FIG. However, in the present embodiment, the porous soft material 52 is disposed so as to fill a gap formed between the inner surface 50A of the groove portion 50 and the surface 20A of the substrate 20.

  As a result, when the foamed resin layer 30 is molded, when the foamable resin material forming the foamed resin layer 30 is foamed, the soft material 52 (the fitted member 53 and the covering member 54) is formed in the groove portion 50. Thus, the flow of the foamable resin material to the outside (indicated by the arrow P1 in FIG. 10) is blocked, and the situation of leaking to the outside is suppressed. More precisely, a part of the foamable resin material soaks into the porous soft material 52, and the flow stops in the inside. Further, since the soft material 52 is porous, when the foamable resin material is foamed, the air in the foamed resin layer molding space S1 can pass through the soft material 52 and exit to the outside. Thereby, the situation where a void (bubble) generate | occur | produces in the foamed resin layer 30 after shaping | molding can be suppressed.

  From the above, in the present embodiment, when the foamed resin layer 30 is injection-molded using the skin material 40 formed by sewing the pair of skin pieces 45 and 46, the foamable resin material is The situation where it leaks outside can be prevented. In other words, the glove box 10 of the present embodiment can be molded by injecting and filling a foamable resin material between the base material 20 and the skin material 40.

  Conventionally, when the skin material is genuine leather, after forming the foamed resin layer, the skin material is manually pasted on the surface. It is necessary to perform such affixing work in accordance with the surface shape (three-dimensional shape) of the foamed resin layer so as not to cause wrinkles or the like on the skin material. It was work. In this regard, with the configuration of the present embodiment, even when a skin material 40 formed by sewing a pair of skin pieces 45 and 46 such as genuine leather is used, the skin material 40 is manually operated. There is no need to stick, and productivity can be further increased.

  The soft material 52 includes a fitted member 53 fitted into the groove portion 50 and a covering member 54 that covers the fitted member 53 and covers the opening of the groove portion 50. Yes.

  In the present embodiment, the member to be fitted 53 is fitted into the groove 50 and the opening of the groove 50 is covered with the covering member 54. As a result, the groove 50 in the skin material peripheral end portion 42 is blocked by the fitted member 53, and the flatness of the surface of the skin material peripheral end portion 42 can be secured by the covering member 54. As a result, a situation in which a gap is generated between the skin material peripheral end portion 42 and the base material 20 can be more reliably suppressed.

  Moreover, in this embodiment, it is set as the structure which folds the skin material peripheral edge part 42 inside the glove box 10. FIG. For this reason, the terminal process (for example, the cutting process of a surplus part etc.) of the skin material 40 becomes unnecessary, and productivity can be made higher.
