Description

[Technical Field]

[0001] The present invention relates to an edge protection member for vehicle interior materials that is attached to an edge within an area defined by regulations for protrusions in vehicle interiors. [Background technology]

[0002] Kenaf is known as a material for the base material of a seat backboard. Such a base material is manufactured through a heat pressing process, a molding process, etc., and the peripheral edge is cut off during the molding process, leaving an edged end at the cut location as a molding trace.

[0003] Automobile interior parts are required to comply with regulations on protrusions within the vehicle cabin, and seat backboards are included in these regulations. Specifically, the part of the seat backboard that may come into contact with the occupant's head must meet certain requirements (hereinafter referred to as the internal impact requirements) such as the radius of curvature.

[0004] In other words, the cut portions of the base material described above do not meet the internal projection requirements in their raw state, so secondary processing is performed to round the edges. Furthermore, depending on the thickness of the base material, even rounding the edges may not meet the internal projection requirements, and in such cases, a thickness that is not actually necessary for the function of the base material may be secured just to clear the regulations.

[0005] In order to reduce such processing man-hours and wasted materials, it is conceivable to use an edge protection material as shown in Patent Document 1. In other words, the cutting portion (edge) of the substrate is covered with an edge protection material to clear the regulations. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Publication No. 09-226822 Summary of the Invention [Problem to be solved by the invention]

[0007] However, the edge protection material disclosed in Patent Document 1 only describes that it has a substantially U-shaped cross section, and does not mention anything about the requirement for inward protrusion. Therefore, even if it is attached to the end to cover the edge, there is a problem that it may not satisfy the requirement for inward protrusion depending on its surface shape and hardness.

[0008] Therefore, an object of the present invention is to provide an interior edge protection material for a vehicle that satisfies the requirements for inward collision simply by being attached to an edge provided in an area specified by regulations on protrusions inside a vehicle interior. [Means for solving the problem]

[0009] To solve the above problems, the edge protection material for vehicle interior materials of the present invention employs the following means.

[0010] That is, the first aspect of the present invention is an interior edge protection material for a vehicle that is attached to an end portion that is provided in a specified area of ​​the vehicle interior protrusion regulations, and that has an attachment portion that is attached to the end portion, and a covering portion that is provided continuously from the attachment portion and covers the edge of the end portion with a curved shape that has hardness that meets the specified requirements for the specified area.

[0011] According to the first aspect of the present invention, the vehicle interior edge protection material attached to the end portion is subject to the vehicle interior protrusion regulations instead of the end portion, and the curved shape of the covering portion satisfies the requirements for inward protrusion. Therefore, the regulations can be met simply by attaching the vehicle interior edge protection material to the end portion.

[0012] The second invention of the present invention is related to the first invention, wherein the covering portion has a cylindrical shape with an open cross section so as to be able to cover the edge formed continuously along the end portion extending with a constant cross-sectional shape, the mounting portion has a pair of clamping bodies formed at one end and the other end in the cylindrical circumferential direction of the covering portion so as to be able to clamp the end portion from the plate thickness direction, and further has a first core material which is more rigid than the covering portion and is contained in the covering portion so as to extend in the cylindrical circumferential direction.

[0013] According to the second invention, when the covering portion opens as the end portion is clamped by the pair of clamping bodies, the first core material applies force to the pair of clamping bodies in the closing direction, making it difficult for the vehicle interior material edge protection material to come loose from the end portion.

[0014] The third invention of the present invention is the second invention, wherein the covering portion is elastically deformable so as to conform to the curved extending end portion, and further comprises a second core material that is contained in the covering portion so as to extend in the axial direction of the tube, and that plastically deforms in accordance with the elastic deformation of the covering portion that bends along the curved region of the end portion, and that maintains the shape of the deformed covering portion.

[0015] According to the third invention, the plastic deformation of the second core material makes it possible to hold the edge protection material for vehicle interior materials in a bent shape, making it easier to attach the edge protection material for vehicle interior materials to curved areas at the end.

[0016] A fourth aspect of the present invention is that, in the third aspect, the first core material and the second core material are made from a single flat metal plate, and the second core material extends linearly so as to connect the multiple first core materials contained within at intervals in the axial direction of the tube.

[0017] According to the fourth aspect of the present invention, if the first core material and the second core material were constructed separately, a thickness would be required to avoid interference between the second core material and the first core material extending in the axial direction of the tube, but the thickness of the covering portion can be reduced accordingly. Furthermore, when a desired length of edge protection material for vehicle interior materials is required, it can be easily cut by cutting the edge protection material for vehicle interior materials in the axial direction between adjacent second core materials.

[0018] A fifth aspect of the present invention is the attachment portion according to any one of the second to fourth aspects, wherein the pair of clamping bodies have a pair of opposing clamping surfaces that come into close planar contact with the end portions.

[0019] According to the fifth invention, the first core material applies force to the pair of clamping bodies in the closing direction, causing the ends and the clamping surfaces to adhere to each other in a planar manner, making it even more difficult for the vehicle interior edge protection material to slip out from the ends.

[0020] A sixth aspect of the present invention is the fifth aspect, wherein the pair of clamping surfaces face each other and move away from each other toward the outside of the opening so that the end can be inserted through the opening between the pair of clamping bodies.

[0021] According to the sixth aspect of the present invention, the side that receives the end portion is widely opened, making it easier to attach the edge protection material for a vehicle interior material. [Brief explanation of the drawings]

[Figure 6] FIG. 6 is a cross-sectional view taken along line VI-VI in FIG. 5. DETAILED DESCRIPTION OF THE INVENTION

[0023] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, directions such as front, back, up, down, left, and right refer to the directions shown in each drawing. In the following description, when a specific reference drawing is not shown or when there is no reference symbol corresponding to a reference drawing, any of Figures 1 to 6 will be referred to as appropriate.

[0024] (Outline of vehicle interior edge protection material 1) As shown in FIG. 1 , the vehicle interior edge protection material 1 is attached to an edge 5 so that the edge 5A of the edge 5 is not exposed. The edge 5 to which the vehicle interior edge protection material 1 is attached is located in an area specified by the vehicle interior protrusion regulations. Examples of the edge 5 include molding marks left on the edge of a molded product such as a backboard base material or an instrument panel. The edge 5 extends along the periphery of the molded product to have a uniform cross-sectional shape, and the edge 5A is formed continuously along the edge 5. In practice, such edge 5A is covered with a soft skin or felt, but in the evaluation of the vehicle interior protrusion regulations, any skin or felt that does not have a predetermined hardness is considered to be nonexistent. Therefore, such edge 5A requires secondary processing such as rounding.

[0025] Unlike skins, felts, etc., which are considered to be non-existent, the edge protection material 1 for vehicle interior materials has a Shore A hardness of 50 or more. In other words, a Shore A hardness of 50 or more is a hardness that is subject to the regulations on protrusions in vehicle interiors, and by having this hardness, the edge protection material 1 for vehicle interior materials is subject to the regulations on protrusions in vehicle interiors instead of the end portion 5, unlike skins, felts, etc. Specifically, the edge protection material 1 for vehicle interior materials is manufactured into a long shape by extrusion molding soft vinyl chloride. When in use, it is cut to the required length according to the length of the end portion 5.

[0026] (Configuration of vehicle interior edge protection material 1) The vehicle interior edge protection material 1 has an attachment portion 2 that is attached to the end portion 5, a covering portion 3 that covers the edge 5A of the end portion 5 with a curved shape that meets the specified requirements according to the specified area, and a core material 4 that is enclosed in the covering portion 3.

[0027] (Covering part 3) 2 and 3, the covering portion 3 is provided continuously from the mounting portion 2 and has a cylindrical shape with a C-shaped cross section (open cross section) so as to be able to cover the edge 5A. The outer peripheral surface of the covering portion 3 has a shape that clears the vehicle interior protrusion regulations, i.e., a shape that satisfies the inward protrusion requirements, and is formed into a curved surface with an R4, for example. The R shape of the outer peripheral surface can be changed as appropriate depending on the specified area of ​​the vehicle interior protrusion regulations.

[0028] The specified area is an area in the vehicle cabin where the head of a seat occupant may come into contact. Examples of interior parts in which the edge 5 as the molding mark described above may be formed in such a specified area include sun visors, coat hangers, roofs, instrument panels, and backboards for front and rear seats. The requirements for inward collision required for each interior part are different. Therefore, for example, if an instrument panel is required to have a radius of curvature R≧3.2, the outer peripheral surface of the covering portion 3 may have a radius of curvature R of, for example, 3.2.

[0029] (Attachment part 2) 2 and 3, the attachment portion 2 secures the edge protection material 1 for vehicle interior materials to the end portion 5, and maintains a state in which the edge 5A of the end portion 5 is covered with the covering portion 3. The attachment portion 2 has a pair of clamping bodies 2A, 2B formed at one end and the other end in the cylindrical circumferential direction of the covering portion 3 so that the end portion 5 can be clamped in the plate thickness direction. When the edge protection material 1 for vehicle interior materials is attached to the end portion 5, the end portion 5 is inserted into the covering portion 3 through an opening 2X between the pair of clamping bodies 2A, 2B.

[0030] Here, in the vehicle interior material edge protection material 1, the clamping surfaces 2P, 2Q formed on the pair of clamping bodies 2A, 2B make it easier to insert the end portion 5, and after insertion, there is no need for bonding work using adhesives or the like.

[0031] The clamping surfaces 2P, 2Q face the end portion 5 so as to be in close contact with the end portion 5. The clamping surfaces 2P, 2Q are inclined with respect to the insertion direction, and are opposed surfaces that are inclined so as to move away from each other as they move toward the outside of the opening 2X. Specifically, the minimum width W1 of the opposed clamping surfaces 2P, 2Q is smaller than the thickness of the end portion 5, and the maximum width W2 is also smaller than the thickness of the end portion 5. For example, if the thickness of the end portion 5 is 2.5 mm, then W1 = 1.5 mm and W2 = 4.0 mm.

[0032] Therefore, the end 5 inserted through the opening 2X can be guided by the clamping surfaces 2P, 2Q toward the inside of the covering portion 3. In addition, the pair of clamping bodies 2A, 2B have return portions 2C, 2D formed in the portion with the smallest width W1. When the end 5 is inserted, the return portions 2C, 2D elastically deform, causing the clamping surfaces 2P, 2Q to come into close contact with the end 5. Because the attachment portion 2 is made of soft vinyl chloride, friction is generated between the clamping surfaces 2P, 2Q and both side surfaces of the end 5, preventing the vehicle interior edge protection material 1 from easily slipping out of the end 5.

[0033] (Core 4) As shown in Figure 4, the core material 4 is made of a single flat metal plate, and is a flat metal processed product with a first core material 4A and a second core material 4B that are flush with each other before being enclosed in the covering part 3. While the attachment part 2 and the covering part 3 are made of soft vinyl chloride, the core material 4 is made of metal, so it is highly rigid and can be plastically deformed.

[0034] Before processing, the core material 4 has a second core material 4B extending linearly and a first core material 4A extending perpendicularly from the second core material 4B on both sides. A plurality of first core materials 4A are formed intermittently at intervals along the longitudinal direction of the second core material 4B. The intervals are preferably equal and greater than the width of the first core material 4A. The core material 4 is then bent to curve the first core material 4A, and extruded together with soft vinyl chloride to obtain an edge protection material 1 for vehicle interiors, in which the core material 4 is enclosed within the covering portion 3.

[0035] 2, the first core material 4A enclosed in the sheath 3 after bending extends in the circumferential direction of the sheath 3. Specifically, like the sheath 3, the first core material 4A has a C-shaped cross section and extends from one end of the sheath 3 to the other, with a central angle θ of 180 degrees or more in cross section. The central angle θ is preferably set to a value such that each end 4S, 4T of the first core material 4A extends beyond the reference line L.

[0036] Here, the reference line L is an extension of the line segment (minimum width W1) that connects the shortest distance from the return portion 2C to the return portion 2D of the pair of clamping bodies 2A, 2B. By enclosing such a first core material 4A in the covering portion 3, the edge protection material 1 for vehicle interior materials further improves the force with which the pair of clamping bodies 2A, 2B clamp the end portion 5.

[0037] The first core material 4A and the second core material 4B may be formed separately, but in that case, the thickness of the covering portion 3 is required to enable the second core material 4B to extend in the axial direction of the cylinder while avoiding interference with the first core material 4A. In this regard, because the core material 4 is formed from a single flat metal plate, the thickness of the covering portion 3 can be made smaller than when the core materials 4A and 4B are formed separately.

[0038] 3, the second core material 4B contained in the covering portion 3 extends in the axial direction through the center of the interior of the covering portion 3. When cutting the edge protection material 1 for vehicle interior materials to the required length, cutting along this cross section allows for easy cutting, as the only metal portion remaining is the second core material 4B.

[0039] (Example of edge protection material 1 for vehicle interior materials) 5 and 6, an example of attaching the edge protection material 1 for vehicle interior materials to a base material 9A of a backboard 9 will be described as an embodiment of the edge protection material 1 for vehicle interior materials. Note that Fig. 5 shows a part of the base material 9A, and a cutout is provided to make the shape of the end portion 9B easier to understand.

[0040] The base material 9A is made of kenaf fiber and is manufactured through a heat pressing process, a molding process, etc. In the molding process, the kenaf plate material obtained in the heat pressing process is press-molded by an upper mold and a lower mold to form a predetermined product shape, and the peripheral portion is cut off.

[0041] Therefore, as shown in Figures 5 and 6, an end portion 9B having an edge 9C as a molding trace is formed on the base material 9A. That is, the peripheral edge portion of the base material 9A is bent so as to stand up, and the end portion 9B is formed. In addition, at the corners of the base material 9A, the end portion 9B extends with a curve, and a curved region 9D is formed. Please refer to Figures 11 and 12 of Japanese Patent Laid-Open No. 2023-84393, which disclose the manufacturing process of the backboard (the process of forming the raw edge).

[0042] If edge protection material 1 for vehicle interior materials is attached to such end 9B, edge 9C is covered, and edge protection material 1 for vehicle interior materials becomes subject to the vehicle interior protrusion regulations in place of end 9B. The outer peripheral surface of covering portion 3 of edge protection material 1 for vehicle interior materials has a curved shape (e.g., a curved surface with R4) that meets the vehicle interior protrusion regulations, so the inward projection requirements are met. Therefore, the regulations can be met simply by attaching edge protection material 1 for vehicle interior materials to end 9B.

[0043] Typically, a straight edge protection material 1 for vehicle interior materials is used with a predetermined length and is inserted sequentially along the end 9B, but in this case, it will come across a curved region 9D along the way. In this case, for example, if the edge protection material 1 for vehicle interior materials is bent in advance to correspond to the curvature of the curved region 9D, the plastic deformation of the second core material 4B will allow the bent shape of the edge protection material 1 for vehicle interior materials to be maintained. This makes it easier to attach the edge protection material 1 for vehicle interior materials to the curved region 9D of the end 9B.

[0044] Furthermore, focusing on the edge protection material 1 for vehicle interior materials after attachment to the end portion 9B, as shown in FIG. 6, the pair of clamping bodies 2A and 2B clamping the end portion 9B elastically deform at their return portions 2C and 2D, so that the clamping surfaces 2P and 2Q are in planar contact with the end portion 5. Furthermore, as the pair of clamping bodies 2A and 2B elastically deform, the covering portion 3 also slightly expands. As described above, the first core material 4A is contained within the covering portion 3, which further improves the clamping force of the pair of clamping bodies 2A and 2B in the edge protection material 1 for vehicle interior materials, increasing the friction between the clamping surfaces 2P and 2Q and the end portion 9B, making it more difficult for the edge protection material 1 for vehicle interior materials to slip off the end portion 9B. Furthermore, because the covering portion 3 has a C-shaped cross section, the bending stress during expansion is less likely to concentrate in one area than, for example, a U-shaped cross section. With a U-shaped cross section, bending stress concentrates at two points with large curvatures, which can lead to cracks and deterioration.

[0045] To summarize the above, the vehicle interior edge protection material 1 according to this embodiment has the following configuration: Note that the reference numerals in parentheses below correspond to the respective components shown in the above embodiment.

[0046] That is, the vehicle interior edge protection material (1) is attached to an end (5) provided in a specified area of ​​the vehicle interior protrusion regulations. The vehicle interior edge protection material (1) has an attachment part (2) attached to the end (5), and a covering part (3) provided continuously from the attachment part (2) and covering the edge (5A) of the end (5) with a curved shape having hardness that satisfies the specified requirements for the specified area.

[0047] According to the above-mentioned configuration, the vehicle interior edge protection member (1) attached to the end portion (5) is subject to the vehicle interior protrusion regulations instead of the end portion (5), and the inward protrusion requirements are met by the curved shape of the covering portion (3). Therefore, the regulations can be met simply by attaching the vehicle interior edge protection member (1) to the end portion (5).

[0048] The covering portion (3) has a cylindrical shape with an open cross section so as to be able to cover an edge (5A) formed continuously along the end portion (5) extending with a constant cross-sectional shape, and the mounting portion (2) has a pair of clamping bodies (2A, 2B) formed at one end and the other end in the cylindrical circumferential direction of the covering portion (3) so as to be able to clamp the end portion (5) from the plate thickness direction. The vehicle interior edge protection material (1) further has a first core material (4A) which is higher in rigidity than the covering portion (3) and is enclosed in the covering portion (3) so as to extend in the cylindrical circumferential direction.

[0049] According to the above configuration, when the covering portion (3) opens as the end portion (5) is clamped by the pair of clamping bodies (2A, 2B), the first core material (4A) applies a force to the pair of clamping bodies (2A, 2B) in the closing direction, making it possible to make the vehicle interior material edge protection material (1) less likely to come off from the end portion (5).

[0050] The covering portion (3) is elastically deformable so as to fit along the curved extending end portion (5). The vehicle interior edge protection material (1) further includes a second core material (4B) that is enclosed in the covering portion (3) so as to extend in the axial direction of the tube, and that plastically deforms with the elastic deformation of the covering portion (3) that bends along the curved region (9D) of the end portion (5), thereby maintaining the shape of the deformed covering portion (3).

[0051] According to the above configuration, the edge protection material (1) for vehicle interior materials can be held in a bent shape by the plastic deformation of the second core material (4B), making it easier to attach the edge protection material (1) for vehicle interior materials to the curved region (9D) of the end portion (5).

[0052] The first core material (4A) and the second core material (4B) are made of a single flat metal plate, and the second core material (4B) extends linearly so as to connect the multiple first core materials (4A) contained therein at intervals in the axial direction of the cylinder.

[0053] According to the above configuration, if the first core material (4A) and the second core material (4B) were constructed separately, a thickness would be required to avoid interference between the second core material (4B) and the first core material (4A) extending in the axial direction of the tube, but this would allow the thickness of the covering portion (3) to be reduced accordingly. Furthermore, when a desired length of the edge protection material (1) for vehicle interior materials is required, it can be easily cut by cutting the edge protection material (1) for vehicle interior materials in the axial direction between adjacent second core materials (4B).

[0054] The mounting portion (2) has a pair of opposing clamping surfaces (2P, 2Q) in the pair of clamping bodies (2A, 2B) that come into close planar contact with the end portion (5).

[0055] According to the above configuration, the first core material (4A) applies a force to the pair of clamping bodies (2A, 2B) in the closing direction, and the end portion (5) and the clamping surface (2P, 2Q) come into close contact with each other in a planar manner, making it even more difficult for the vehicle interior edge protection material (1) to slip out of the end portion (5).

[0056] The pair of clamping surfaces (2P, 2Q) are opposed to each other so as to move away from each other toward the outside of the opening (2X) so that the end portion (5) can be inserted from the opening (2X) between the pair of clamping bodies (2A, 2B).

[0057] According to the above-mentioned configuration, the side that receives the end portion (5) is widely opened, so that the vehicle interior edge protection member (1) can be easily attached.

[0058] Other Embodiments Although one embodiment of the present invention has been described above, the present invention can be embodied in various forms other than the above embodiment.

[0059] 1. In the above embodiment, the edge is described as a molding mark remaining on the edge of a molded product, but the vehicle interior material edge protection material may be attached to the molding mark (protrusion) remaining on the surface of the molded product, and in that case, the regulations on protrusions inside the vehicle interior will still be met.

[0060] 2. In the above embodiment, the clamping surface of the attachment part is brought into planar contact with the end part, making it difficult for the edge protection material for vehicle interior materials to slip off from the end part due to frictional force, but it may also be fixed by bonding with an adhesive. For example, the attachment part may be shaped so as to have line contact with the end part, and such attachment part and the end part may be fixed with an adhesive.

[0061] 3. In the above embodiment, the attachment portion and the covering portion are made of the same material, and both have a Shore A hardness of 50 or more, but it is sufficient that at least the covering portion has a Shore A hardness of 50 or more, and for example, the attachment portion may be molded from a material other than soft polyvinyl chloride. The material of the covering portion is not limited to soft polyvinyl chloride as long as it can ensure a Shore A hardness of 50 or more.

[0062] 4. In the above embodiment, the outer peripheral surface of the covering portion is formed in a circular shape and has a C-shaped cross section, but the covering portion may have any open cross section as long as it satisfies the regulations for protrusions in the vehicle interior (meets the requirements for protrusions in the vehicle interior). For example, the cross section may be U-shaped, or may have an elliptical or heart-shaped open cross section.

[0063] 5. In the above embodiment, the core material is contained in the covering portion, but the core material may not be present. Also, for example, only the first core material may be contained in the covering portion, in which case the first core material having a C-shaped cross section may extend continuously in the axial direction of the tube. Furthermore, the core material may be exposed on the outer or inner peripheral surface of the covering portion.

[0064] 6. In the above embodiment, the core material is made up of a single metal flat plate, but the first core material and the second core material may be separate.

[0065] 7. In the above embodiment, the first core material extends from one end of the covering portion to the other end in the circumferential direction of the tube, and the central angle in cross section is 180 degrees or more. However, the central angle may be smaller than 180 degrees. In other words, from the perspective of simply increasing the rigidity (stiffening) of the covering portion, a first core material with θ<180 degrees may be included. In this case, it is desirable to include the first core material so as to span the center of the covering portion, which is most susceptible to bending stress.

[0066] 8. In the above embodiment, each of the pair of opposing clamping surfaces is inclined, but one of the pair of clamping surfaces may be parallel to the insertion direction of the end portion, and the other may be inclined. [Explanation of symbols]
