Description

[Technical Field]

[0001] The present invention relates to a first part and a composite part. [Background technology]

[0002] As the first component and the composite component, Patent Document 1 discloses an interior material N attached to a door base 10. An upper end 1b of the interior material N and another end of the interior material N are arranged in contact with the door base 10. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Microfilm of Utility Model Application No. 62-006611 (Utility Model Application No. 63-114855) Summary of the Invention [Problem to be solved by the invention]

[0004] In the interior material N disclosed in the above-mentioned Patent Document 1, there was a risk that gaps would occur between the upper end 1b of the interior material N (first part) and the door base 10 (second part), or between other ends of the interior material N and the door base 10, resulting in poor fit and a poor appearance.

[0005] The present invention has been made to solve the above-mentioned problems, and has an object to provide a first part and a composite part that can be attached to a second part in a good-looking manner. [Means for solving the problem]

[0006] In order to solve the above problem, the first part according to the present invention is a first part that can be attached to a second part, and is characterized by having a groove-shaped bending start portion that is provided at a distance from an end portion that is arranged on the second part side.

[0007] According to the first part of the present invention, when attaching the first part to the second part, the end of the first part that is located on the second part side can be bent from the bend starting point, allowing the end of the first part that is located on the second part side to come into contact with the second part. This reliably prevents gaps from occurring between the end of the first part and the second part, improving fit and appearance. As a result, it is possible to provide a first part that can be attached to the second part with a good appearance.

[0008] In the first component according to the present invention, the bend start portion is preferably formed on the back surface. By providing the groove-shaped bend start portion on the back surface, which is not the design surface, the first component can be attached to the second component in a more attractive manner.

[0009] Furthermore, in the first part according to the present invention, it is preferable that the first part has a curved portion and the bend starting point is provided on the inner side of the curved portion. This makes it possible to bend the end of the first part that is located on the second part side from the bend starting point, i.e., the curved portion, when attaching the first part to the second part, and thus makes it possible to bend the first part more reliably. Therefore, it is possible to make the end of the first part that is located on the second part side contact the second part more reliably.

[0010] Furthermore, in the first part according to the present invention, it is preferable that the first part is an automotive interior part. This allows the end of the automotive interior part to be bent from the bending start point when attaching the automotive interior part to the second part, making it possible to bring the end of the automotive interior part into contact with the second part. This reliably prevents gaps from forming between the end of the automotive interior part and the second part, improving fit and appearance. As a result, it is possible to provide an automotive interior part that can be attached to the second part with a good appearance.

[0011] Furthermore, a composite part according to the present invention is a composite part in which a first part is attached to the second part, and the second part includes a locking portion that locks an end of the first part. This allows the end of the first part that is located on the second part side to be bent from the bend starting point when attaching the first part to the second part, making it possible for the end of the first part that is located on the second part side to come into contact with the locking portion of the second part. This reliably prevents gaps from occurring between the end of the first part and the second part, improving fit and appearance. As a result, a composite part can be provided that allows the first part to be attached to the second part in an attractive manner.

[0012] In the composite part according to the present invention, the locking portion is preferably a recess or a protrusion. This allows the locking portion to be formed with a simple and attractive structure. Therefore, it is possible to provide a composite part that allows the first part to be attached to the second part with an attractive appearance. [Effects of the Invention]

[0013] According to the present invention, it is possible to provide a first part that can be attached to a second part with a good appearance, and a composite part that can attach the first part to the second part with a good appearance. [Brief explanation of the drawings]

FIG. DETAILED DESCRIPTION OF THE INVENTION

[0015] Hereinafter, an embodiment of a front pillar garnish to which a first part and a composite part according to the present invention are applied will be described with reference to the drawings. However, the present invention is not limited to this embodiment and can be embodied in various forms with various modifications and improvements based on the knowledge of those skilled in the art.

[0016] As shown in Fig. 1, the front pillar garnish 20 is provided on the passenger compartment side of a front pillar 12 of a vehicle M. The front pillar 12 includes a front pillar portion 12a that extends diagonally downward and forward from the front end of a roof side rail 11 provided at the upper end of the passenger compartment side, and a rear pillar portion 12b that branches into two from the upper end of the front pillar portion 12a and extends downward toward the vehicle. The front pillar may also be referred to as an A-pillar.

[0017] Furthermore, although the first part and composite part according to the present invention are intended to be applied to a front pillar garnish, they are not limited to this and can be applied to garnishes for pillars other than front pillars (such as rear pillars), can be applied to automotive interior parts other than pillar garnishes, and can be applied to other parts other than automotive interior parts.

[0018] The front pillar portion 12a and the rear pillar portion 12b are aligned in the front-to-rear direction of the vehicle, and a glass plate 15 is disposed between the front pillar portion 12a and the rear pillar portion 12b. This glass plate 15 is fixed to the front pillar 12 using, for example, an adhesive. A windshield glass 14 is disposed on the inner side of the front pillar portion 12a in the vehicle width direction. An outer end of the windshield glass 14 in the vehicle width direction is fixed to the front pillar portion 12a using, for example, an adhesive. A front side door 13 is disposed below the rear pillar portion 12b and on the vehicle rear side of the rear pillar portion 12b.

[0019] A front pillar garnish 20 is attached to the interior side of the front pillar 12. The front pillar garnish 20 includes a front garnish portion 21 that covers the front pillar portion 12a from the interior side of the vehicle, and a rear garnish portion 22 that covers the rear pillar portion 12b from the interior side of the vehicle. The front pillar garnish 20 corresponds to a composite part, with the front garnish portion 21 corresponding to a first part and the rear garnish portion 22 corresponding to a second part. The composite part is a part in which the first part is attached to the second part. The first part is a part that can be attached to the second part. The second part can also be referred to as the attachment point of the first part. It is preferable that the first part is an automotive interior part.

[0020] The front garnish portion 21 is disposed so as to extend diagonally downward toward the front of the vehicle from both front ends of the ceiling 16 provided at the upper part of the interior. The rear garnish portion 22 is disposed so as to branch into two parts from the upper end of the front garnish portion 21 and extend downward toward the vehicle. The front garnish portion 21 and the rear garnish portion 22 are aligned along the fore-and-aft direction of the vehicle. The front garnish portion 21 and the rear garnish portion 22 are formed in a gutter shape that opens outward in the vehicle width direction.

[0021] (Recessed locking part: with skin) As shown in Fig. 3A, the front garnish portion 21 has a base material 21a formed in a gutter shape that opens outward in the vehicle width direction, and a skin material 21b laminated on the surface of the base material 21a. The base material 21a is made of synthetic resin. Examples of synthetic resins that can be used include thermosetting resins such as phenolic resin and melamine resin, and thermoplastic resins such as polyethylene, polypropylene, acrylic resin, and polycarbonate. Note that the base material 21a is not limited to synthetic resin, and may be made of other materials, such as foamable resins such as polyurethane foam.

[0022] The covering material 21b has a surface material (not shown) located on the surface of the covering material 21b, and the surface material is preferably formed of fabric or material (hereinafter sometimes referred to as fabric or the like) such as woven fabric, knitted fabric, or nonwoven fabric. The covering material 21b is adhered to the base material 21a with, for example, an adhesive. The covering material 21b may also have a backing material laminated on the back side of the surface material.

[0023] Furthermore, it is more preferable that the surface material be formed from a knitted material. A knitted material is a fabric made by knitting yarn into loops using needles, and is a fabric with higher elasticity than a woven fabric. A woven fabric is generally a fabric woven using two threads, a warp thread and a weft thread. A nonwoven fabric is a sheet-like fabric or material made by intertwining fibers without weaving them. Furthermore, the fibers forming the surface material and backing material can be synthetic fibers made of, for example, polyester, PP (polypropylene), ethylene-propylene copolymer, or other polyolefin resins.

[0024] Similar to the front garnish portion 21, the rear garnish portion 22 has a base material 22a formed in a gutter shape that opens outward in the vehicle width direction, and a skin material 22b laminated on the surface of the base material 22a, as shown in FIG. 3A.

[0025] As shown in Fig. 2, the front garnish portion 21 has an upper end portion 21c, a lower end portion 21d, and a connecting portion 21e. The upper end portion 21c is attached to the ceiling 16, and the lower end portion 21d is attached to the dashboard 17. An upper end portion 22c of the rear garnish portion 22 is attached to the connecting portion 21e. The rear garnish portion 22 has an upper end portion 22c and a lower end portion 22d. The lower end portion 22d is attached to the dashboard 17.

[0026] 3A and 3B, the connection portion 21e of the front garnish portion 21 has a groove-shaped bend starting portion 21a2 provided at a predetermined distance from the end portion 21a1 arranged on the rear garnish portion 22 side. The bend starting portion 21a2 is a starting point from which the portion from the bend starting portion 21a2 to the end portion 21a1 can be bent. Because the bend starting portion 21a2 is formed in a groove shape (recess), it is easier to bend than other portions where no groove (recess) is formed, and functions as a bending starting point.

[0027] It can be said that a flexible portion is provided between bend starting point 21a2 and end portion 21a1, which can bend when end portion 21a1 is in contact with the inner wall surface (contact portion) of recessed portion 22a2 of rear garnish portion 22 via skins 21b and 22b. In Fig. 3A, the solid line indicates a state in which the portion from bend starting point 21a2 to end portion 21a1 is bent. On the other hand, the two-dot chain line indicates a state in which end portion 21a1 is not in contact with the inner wall surface (contact portion) of recessed portion 22a2 of rear garnish portion 22 via skins 21b and 22b, and the portion from bend starting point 21a2 to end portion 21a1 is not bent.

[0028] The bend starting point 21a2 is provided on the back surface of the front garnish portion 21. Furthermore, the connecting portion 21e of the front garnish portion 21 has a curved portion 21a3, and the bend starting point 21a2 is provided on the inner surface side of the curved portion 21a3. In this embodiment, the bend starting point 21a2 is provided on the curved portion 21a3, but it may also be provided on a flat portion. Furthermore, the end of the skin material 21b is bent to cover the end 21a1 of the base material 21a.

[0029] The rear garnish portion 22 has a recess 22a2 that is an engaging portion that engages with the end portion 21a1 of the front garnish portion 21. The recess 22a2 is provided at an upper end portion 22c of the rear garnish portion 22 (which can be referred to as a connecting portion of the rear garnish portion 22) along a connecting line that connects the front garnish portion 21 and the rear garnish portion 22 (which can be referred to as a joining line that joins the front garnish portion 21 and the rear garnish portion 22). The recess 22a2 has a U-shaped cross section that opens toward the end portion 21a1 of the front garnish portion 21, and one end of the main body portion 22a1 of the base material 22a is connected to one open end of the recess 22a2. An extended extension portion 22a3 is formed at the other open end of the recess 22a2, and the extended extension portion 22a3 is fastened to the front garnish portion 21 by a fastening member (not shown). Examples of the fastening member include screws, rivets, clips, engaging claws, etc. The end of the skin material 22b is provided so as to extend into the recess 22a2 of the base material 22a.

[0030] The end portion 21a1 of the front garnish portion 21 is inserted into the recess 22a2 of the rear garnish portion 22, and the end portion 21a1 of the front garnish portion 21 contacts the inner wall surface on one opening end side of the recess 22a2, thereby engaging the end portion 21a1 of the front garnish portion 21 with the recess 22a2 of the rear garnish portion 22.

[0031] The front pillar garnish 20 described above is attached to the front pillar 12 using, for example, clips (not shown). Furthermore, a plurality of fitting claws (not shown) protruding toward the lower side of the vehicle are formed on the lower end portions 21d, 22d of the front garnish portion 21 and the rear garnish portion 22 described above. These fitting claws are fitted into fitting holes (not shown) formed in the dashboard 17. As a result, the lower end portions 21d, 22d are fixed to the dashboard 17. Furthermore, a plurality of fitting claws (not shown) protruding toward the upper side of the vehicle are formed on the upper end portion 21c of the front garnish portion 21. These fitting claws are fitted into fitting holes (not shown) formed in the ceiling 16. As a result, the upper end portion 21c is fixed to the ceiling 16.

[0032] (Recessed locking part: no cover material) Furthermore, the front pillar garnish 20 described above is configured so that the skin materials 21b, 22b are laminated on the surfaces of the base materials 21a, 22a. However, as shown in Fig. 3B, a front pillar garnish 120 may be configured so that the skin materials 21b, 22b are not laminated on the surfaces of the base materials 21a, 22a (i.e., formed only from the base material). In this case, the end portion 21a1 is in direct contact with the inner wall surface (contact portion) of the recessed portion 22a2 of the rear garnish portion 22, and the portion from the bending starting point 21a2 to the end portion 21a1 is bent.

[0033] (Protruding locking part: with skin) Furthermore, in the above-described front pillar garnish 20, recessed portions 22a2 are provided as locking portions, but protrusions 222a2 may also be provided as locking portions. In this case, as shown in Fig. 4A, the front pillar garnish 220 includes a front garnish portion 21 and a rear garnish portion 222 that covers the rear pillar portion 12b from the inside of the vehicle compartment. The front pillar garnish 220 corresponds to a composite part, the front garnish portion 21 corresponds to a first part, and the rear garnish portion 222 corresponds to a second part.

[0034] The rear garnish portion 222 is arranged so as to branch into two parts from the upper end of the front garnish portion 21 and extend downward toward the vehicle. The front garnish portion 21 and the rear garnish portion 222 are aligned along the front-to-rear direction of the vehicle. The front garnish portion 21 and the rear garnish portion 222 are formed in a gutter shape that opens outward in the vehicle width direction.

[0035] 4A, the rear garnish part 222 has a base material 222a formed in a gutter shape that opens outward in the vehicle width direction, and a skin material 222b laminated on the surface of the base material 222a. An upper end part 222c of the rear garnish part 222 is attached to the connecting part 21e of the front garnish part 21. A lower end part (not shown) of the rear garnish part 222 is attached to the dashboard 17.

[0036] It can be said that a flexible portion is provided between bend starting point 21a2 and end portion 21a1, which can bend when end portion 21a1 is in contact with the outer wall surface (contact portion) of protrusion 222a2 of rear garnish portion 222 via skins 21b and 222b. In Fig. 4A, the solid line indicates a state in which the portion from bend starting point 21a2 to end portion 21a1 is bent. On the other hand, the two-dot chain line indicates a state in which end portion 21a1 is not in contact with the outer wall surface (contact portion) of protrusion 222a2 of rear garnish portion 222 via skins 21b and 222b, and the portion from bend starting point 21a2 to end portion 21a1 is not bent.

[0037] The rear garnish portion 222 has a protrusion 222a2 that is an engaging portion that engages with the end portion 21a1 of the front garnish portion 21. The protrusion 222a2 is provided at an upper end portion 222c of the rear garnish portion 222 (which can be referred to as a connecting portion of the rear garnish portion 222) along a connecting line that connects the front garnish portion 21 and the rear garnish portion 222. The protrusion 222a2 is formed with a triangular cross section (a triangular wave cross section) that protrudes toward the end portion 21a1 of the front garnish portion 21. One end of the protrusion 222a2 is connected to one end of the main body portion 222a1 of the base material 222a. An extended extension portion 222a3 is formed at the other end of the protrusion 222a2, and the extended extension portion 222a3 is fastened to the front garnish portion 21 by a fastening member (not shown). The end of the skin material 222b extends to the extension 222a3 of the base material 222a.

[0038] The end 21a1 of the front garnish portion 21 is engaged with the protrusion 222a2 of the rear garnish portion 222 by contacting the outer wall surface of the other end side of the protrusion 222a2 via the skin materials 21b and 222b.

[0039] (Protruding locking part: No cover material) Furthermore, the above-described front pillar garnish 220 (having the protruding portion 222a2 on the rear garnish portion 222) has the skin materials 21b, 222b laminated on the surfaces of the base materials 21a, 222a, but as shown in Fig. 4B, a front pillar garnish 320 may be used in which the skin materials 21b, 222b are not laminated on the surfaces of the base materials 21a, 222a (formed only from the base material). In this case, the end portion 21a1 is in direct contact with the outer wall surface (contact portion) of the protruding portion 222a2 of the rear garnish portion 222, and the portion from the bending start point 21a2 to the end portion 21a1 side is bent.

[0040] (Manufacturing method) In the front pillar garnish 20 with a skin material and the front pillar garnish 120 without a skin material described above, the base material 21a of the front garnish portion 21 is the same and can be molded using the same mold. When the skin material 21b is attached to the surface of the molded base material 21a, the front garnish portion 21 with a skin material is formed, while when the skin material 21b is not attached to the surface of the molded base material 21a, the front garnish portion 21 without a skin material is formed. Similarly, in the front pillar garnish 220 with a skin material and the front pillar garnish 320 without a skin material described above, the base material 21a of the front garnish portion 21 is the same and can be molded using the same mold.

[0041] (Actions and Effects of the Embodiments) The front garnish portion 21 (first part) in the above-described embodiment is a part that can be attached to the rear garnish portion 22 (second part), and has a groove-shaped bending starting portion 21a2 that is provided at a distance from the end portion 21a1 that is located on the rear garnish portion 22 side.

[0042] According to the front garnish portion 21 of this embodiment, when attaching the front garnish portion 21 to the rear garnish portion 22, the end portion 21a1 of the front garnish portion 21 located on the rear garnish portion 22 side can be bent from the bending starting point 21a2, and the end portion 21a1 of the front garnish portion 21 located on the rear garnish portion 22 side can be brought into contact with the rear garnish portion 22. This reliably prevents a gap from being formed between the end portion 21a1 of the front garnish portion 21 and the rear garnish portion 22, improving fit and appearance. As a result, it is possible to provide a front garnish portion 21 that can be attached to the rear garnish portion 22 with a good appearance.

[0043] Because the front pillar garnish 20 with a skin material and the front pillar garnish 120 without a skin material use the same base material 21a of the front garnish portion 21, it is possible to bend the end portion 21a1 of the front garnish portion 21 from the bending starting point 21a2, and it is possible to bring the end portion 21a1 of the front garnish portion 21 into contact with the rear garnish portion 22 regardless of whether a skin material is used. In this way, it is possible to improve the fit and appearance of the front pillar garnish for both the front pillar garnish 20 with a skin material and the front pillar garnish 120 without a skin material. As a result, by using a single mold for the base material, it is possible to achieve both reduced manufacturing equipment costs and improved appearance of the front pillar garnish.

[0044] Furthermore, in the front garnish portion 21 according to this embodiment, it is preferable that the bend starting portion 21a2 is formed on the back surface of the front garnish portion 21. By providing the groove-shaped bend starting portion 21a2 on the back surface that is not the design surface (for example, the back surface of the design surface), it becomes possible to attach the front garnish portion 21 to the rear garnish portion 22 in a more attractive manner. The design surface refers to the surface that is visible to people such as occupants, and the back surface refers to the surface that is not visible to people such as occupants.

[0045] Furthermore, in the front garnish portion 21 according to this embodiment, it is preferable that the front garnish portion 21 has a curved portion 21a3 and a bending start portion 21a2 on the inner side of the curved portion 21a3. With this, when attaching the front garnish portion 21 to the rear garnish portion 22, the end portion 21a1 of the front garnish portion 21 located on the rear garnish portion 22 side can be bent from the bending start portion 21a2, i.e., the curved portion 21a3, making it possible to bend the front garnish portion 21 more reliably. Therefore, the end portion 21a1 of the front garnish portion 21 located on the rear garnish portion 22 side can be brought into contact with the rear garnish portion 22 more reliably.

[0046] Furthermore, in the front garnish portion 21 according to this embodiment, it is preferable that the front garnish portion 21 is an automotive interior part. This allows the end portion 21a1 of the automotive interior part to be bent from the bending start portion 21a2 when attaching the automotive interior part to the rear garnish portion 22, making it possible to bring the end portion 21a1 of the automotive interior part into contact with the rear garnish portion 22. This reliably prevents a gap from being formed between the end portion 21a1 of the automotive interior part and the rear garnish portion 22, improving fit and appearance. As a result, it is possible to provide an automotive interior part that can be attached to the rear garnish portion 22 with a good appearance.

[0047] Furthermore, the front pillar garnish 20 (composite part) according to this embodiment is a composite part in which a front garnish part 21 is attached to a rear garnish part 22, and the rear garnish part 22 is characterized in that the front garnish part 21 includes locking parts 22a2, 222a2 that lock the end part 21a1 of the front garnish part 21. This makes it possible, when attaching the front garnish part 21 to the rear garnish part 22, to bend the end part 21a1 of the front garnish part 21 located on the rear garnish part 22 from the bending start part 21a2, and to bring the end part 21a1 of the front garnish part 21 located on the rear garnish part 22 into contact with the locking parts 22a2, 222a2 of the rear garnish part 22. This reliably prevents a gap from being generated between the end part 21a1 of the front garnish part 21 and the rear garnish part 22, improving fit and appearance. As a result, it is possible to provide a front pillar garnish 20 in which the front garnish portion 21 can be attached to the rear garnish portion 22 in a good-looking manner.

[0048] Furthermore, in the front pillar garnish 20 according to this embodiment, the locking portions 22a2, 222a2 are preferably recessed portions 22a2 or protruding portions 222a2. This allows the locking portions 22a2, 222a2 to be formed with a simple and attractive structure. Therefore, it is possible to provide a front pillar garnish 20 that allows the front garnish portion 21 to be attached to the rear garnish portion 22 with an attractive appearance.
