[0019] Hereinafter, several embodiments of the present invention will be described with reference to the drawings. In the second and subsequent embodiments, the same components as those in the first embodiment will be denoted by the same reference numerals as those in the first embodiment, and the description thereof will be omitted or simplified.

[0020] [First embodiment] A first embodiment of the present invention will be described with reference to FIGS. The roof lining 1 of this embodiment is an interior component attached to the ceiling (not shown) of a vehicle body having a sunroof. The roof lining 1 has an opening 21 corresponding to the sunroof, and includes a lining material 2 divided into a plurality of segments 26A-26D, and a plurality of slide fasteners 3A-3D connecting the segments 26A-26D.

[0021] In this specification, the term "sunroof" refers to a window provided in the roof of a vehicle body. In this embodiment, a sunroof is assumed to be provided in the center of the roof of the vehicle body, but the present invention is not limited to this, and the location of the sunroof on the roof can be changed as desired. Furthermore, the vehicle body is not limited to the body of an automobile, and may be the body of any means of transportation.

[0022] In the following, the explanation will be made using the mutually perpendicular X, Y, and Z directions. The X direction corresponds to the traveling direction (front-rear direction) of the vehicle body to which the roof lining 1 is attached, and the Y direction corresponds to the width direction (left-right direction) of the vehicle body. The Z direction is the thickness direction of the lining material 2 and corresponds to the vehicle height direction (up-down direction) of the vehicle body.

[0023] The lining material 2 is a panel-shaped member that extends along the ceiling of the vehicle body. As illustrated in FIG. 3 , the lining material 2 includes a base 24 having a layer structure stacked in the Z direction, and a skin material 25 that covers a surface 244 of the base 24 on the −Z side. The base 24 includes, for example, a urethane layer 241, and a first glass fiber layer 242 and a second glass fiber layer 243 that are disposed on either side of the urethane layer 241. The skin material 25 faces the −Z direction with respect to the space inside the vehicle body, and is formed of, for example, a nonwoven fabric. The base 24 is not limited to including multiple layers, and may be a single layer.

[0024] As shown in FIGS. 1 and 2, the lining material 2 has a curved shape that matches the shape of the vehicle ceiling. For example, the lining material 2 of this embodiment has a first region R1 located at each end in the Y direction, a second region R2 located in the center in the Y direction and located above (on the +Z side of) the first region R1, and an inclined region R3 that connects the first region R1 and the second region R2 and is inclined with respect to the Z direction. The thickness of the inclined region R3 is greater than the thicknesses of the first region R1 and the second region R2, and the first region R1 and the second region R2 have approximately the same thickness. The lining material 2 also has bent portions C located between the first region R1 and the inclined region R3 and between the second region R2 and the inclined region R3.

[0025] 1, the lining material 2 has an opening 21 corresponding to a sunroof in the second region R2. The shape of the opening 21 is not particularly limited as long as it is a shape corresponding to a sunroof. For example, the opening 21 in this embodiment has a substantially rectangular shape with a pair of long sides along the X direction and a pair of short sides along the Y direction. In the lining material 2, the edge of the opening 21 is referred to as the inner edge 22, and the end of the lining material 2 located opposite the inner edge 22 in the X or Y direction is referred to as the outer edge 23.

[0026] As shown in Fig. 1, the lining material 2 is divided into a plurality of segments 26A to 26D. In this embodiment, two division lines L1, L2 are assumed to divide the lining material 2 into the plurality of segments 26A to 26D. The division lines L1, L2 are spaced apart in the Y direction and pass through the opening 21 in a second region R2, which is one of the thinnest regions of the lining material 2. The division lines L1, L2 are arranged along the X direction, which is the traveling direction of the vehicle body.

[0027] In this embodiment, each of the segments 26B and 26C, which are arranged with the opening 21 sandwiched between them in the X direction, is adjacent to segment 26A in the Y direction across segment line L1. Furthermore, each of the segments 26B and 26C is adjacent to segment 26D in the Y direction across segment line L2. Therefore, each of the segments 26A and 26D has two segment end portions 261, which are ends adjacent to segment portions 26B and 26C, on one side in the Y direction. Furthermore, each of the segments 26B and 26C has two segment end portions 261, which are ends adjacent to segment portions 26A and 26D, on both sides in the Y direction.

[0028] Each of the slide fasteners 3A to 3D is attached to each of the divided ends 261 of adjacent segments 26A to 26D to connect the adjacent segments. Specifically, slide fastener 3A connects segments 26A and 26B together, slide fastener 3B connects segments 26A and 26C together, slide fastener 3C connects segments 26B and 26D together, and slide fastener 3D connects segments 26C and 26D together.

[0029] Furthermore, slide fasteners 3A and 3B are arranged on parting line L1 of lining material 2, and slide fasteners 3C and 3D are arranged on parting line L2 of lining material 2. Therefore, slide fasteners 3A to 3D are arranged in second region R2, which is one of the thinnest regions of lining material 2, and extend from opening 21 to outer edge 23 of lining material 2. Furthermore, slide fasteners 3A to 3D are arranged along the X direction, which is the traveling direction of the vehicle body.

[0030] The slide fasteners 3A to 3D may extend in the X direction so as to protrude from the inner edge 22 or the outer edge 23 of the lining material 2. The portions of the slide fasteners 3A to 3D that protrude from the lining material 2 may be housed between the lining material 2 and the vehicle body so as not to be visible from inside the vehicle body.

[0031] The specific configuration of the slide fasteners 3A to 3D is not particularly limited, and any slide fastener can be used. The slide fasteners 3A to 3D have the same configuration, so the following description will be given of the slide fastener 3A as a representative.

[0032] 3, the slide fastener 3A of this embodiment is a typical coil fastener. The slide fastener 3A is attached to each divided end 261 of adjacent divided pieces 26A, 26B and includes a pair of fastener stringers 31, 32 that mesh with each other.

[0033] The fastener stringer 31 includes a tape portion 311 attached to the segment 26A and a coil-shaped element row 312 attached to one end of the tape portion 311. The tape portion 311 is arranged on a surface 245 on the +Z side of the base 24 of the segment 26A and is attached to a divided end portion 261 of the segment 26A by sewing. A sewing position S of the tape portion 311 is, for example, near the element row 312 and at a position at the divided end portion 261 a predetermined distance from an end surface 261P. The element row 312 is arranged on the +Z side surface of the tape portion 311 and attached to an end portion on one side of the tape portion 311 in the width direction. The element row 312 is also arranged on the +Z side of the divided end portion 261 of the segment 26A and overlaps the divided end portion 261 in the Z direction via the tape portion 311.

[0034] The fastener stringer 32 includes a tape portion 321 attached to the segment 26B, and a coil-shaped element row 322 attached to the tape portion 321. The configuration of the fastener stringer 32 is the same as that of the fastener stringer 31, except that it is symmetrical in the Y direction.

[0035] The slide fastener 3A described above connects the segments 26A and 26B together by interlocking the element rows 312 and 322 of the fastener stringers 31 and 32. When the segments 26A and 26B are connected to each other, the end faces 261P of the segment ends 261 of the segments 26A and 26B are in contact with or close to each other in the Y direction. Therefore, the slide fastener 3A is arranged so that it is not exposed to the -Z side from between the segments 26A and 26B.

[0036] The slide fastener 3A may include a slider for meshing the element rows 312 of the fastener stringers 31, 32. Alternatively, the slide fastener 3A may not include a slider, and a slider may be used as a jig.

[0037] (Roof Lining 1 Manufacturing Method) An example of a method for manufacturing the roof lining 1 of this embodiment will be described. First, a process is performed to form the lining material 2 in the form of divided pieces 26A to 26D. A conventional roof lining forming method can be used to form each of the divided pieces 26A to 26D. Furthermore, the divided pieces 26A to 26D may be transported stacked on top of each other to the site of the next process.

[0038] Next, adjacent segments 26A to 26D are connected to each other by corresponding slide fasteners 3A to 3D. Specifically, the fastener stringers 31 (or 32) of the corresponding slide fasteners 3A to 3D are sewn to each of segments 26A to 26D. Thereafter, the fastener stringers 31, 32 of the slide fasteners 3A to 3D are interlocked with each other.

[0039] The roof lining 1 of this embodiment is manufactured in this manner. The roof lining 1 is then attached to the ceiling of a vehicle body having a sunroof. Note that since the roof lining 1 of this embodiment can be transported after manufacture (i.e., transported in a state in which the divided pieces 26A-26D are connected by the slide fasteners 3A-3D), the manufacturing site of the roof lining 1 and the site where it is attached to the vehicle body may be different.

[0040] (Effects of this embodiment) As described above, the roof lining 1 of this embodiment has an opening 21 corresponding to the sunroof of the vehicle body, and comprises a lining material 2 divided into multiple segments 26A to 26D, and multiple slide fasteners 3A to 3D connecting adjacent segments 26A to 26D, and the slide fasteners 3A to 3D traverse the lining material 2 from the opening 21 to the outer edge 23 of the lining material 2.

[0041] According to the above configuration, when manufacturing the roof lining 1, it is sufficient to form the segments 26A to 26D and then connect the segments 26A to 26D to one another, which eliminates the need for a cutting step of removing the portion of the lining material 2 that corresponds to the opening 21. Furthermore, in the above configuration, the connecting portions of the divided pieces 26A to 26D by the slide fasteners 3A to 3D are continuous and linear, so that the divided pieces 26A to 26D can be reliably connected. Therefore, according to this embodiment, the yield rate during the manufacture of the roof lining 1 can be improved.

[0042] In this embodiment, the slide fasteners 3A to 3D are arranged along the fore-and-aft direction (X direction) of the vehicle body. With this configuration, the boundaries between the segments 26A to 26D of the roof lining 1 (i.e., the dividing lines L1, L2) are arranged along the fore-and-aft direction (i.e., the traveling direction) of the vehicle body, so that even if the passengers can see the dividing lines L1, L2 of the roof lining 1, it is possible to prevent the passengers from getting carsick.

[0043] In this embodiment, the lining material 2 has a bent portion C that matches the shape of the ceiling of the vehicle body, but the slide fasteners 3A to 3D are attached to portions of the lining material 2 that are on the same plane (i.e., areas other than the bent portion C).This makes it easier to sew the slide fasteners 3A to 3D to the divided pieces 26A to 26D when manufacturing the roof lining 1.

[0044] In this embodiment, the slide fasteners 3A to 3D are attached to the thinnest portion (specifically, the second region R2) of the lining material 2. This makes it easier to sew the slide fasteners 3A to 3D to the divided pieces 26A to 26D when manufacturing the roof lining 1.

[0045] In this embodiment, the slide fasteners 3A to 3D are attached to adjacent segments 26A to 26D and include a pair of fastener stringers 31, 32 that interlock with each other, and each of the fastener stringers 31, 32 includes a tape portion 311, 321 sewn to one of the segments 26A to 26D and an element row 312, 322 attached to the tape portion 311, 321. In such a configuration, any general slide fastener can be used as the slide fasteners 3A to 3D.

[0046] In this embodiment, the segments 26A to 26D have segment end portions 261 adjacent to other segments 26A to 26D, and the element rows 312, 322 are arranged so as to overlap the segment end portions 261 in the thickness direction (Z direction) of the lining material 2. In this configuration, gaps are prevented from occurring between the divided ends 261 of the adjacent divided pieces 26A to 26D, and the appearance of the roof lining 1 is prevented from being impaired.

[0047] In this embodiment, the lining material 2 has a base 24 having one or more layer structures and a skin material 25 that covers a surface 244 of the base 24 on one side (-Z side) in the thickness direction of the lining material 2, and the slide fasteners 3A to 3D are arranged on the other side (+Z side) in the thickness direction of the lining material 2 relative to the lining material 2. According to this configuration, when the roof lining 1 is attached to the vehicle body so that the skin material 25 faces the space inside the vehicle body, the slide fasteners 3A to 3D are disposed between the ceiling of the vehicle body and the lining material 2. This makes it possible to realize a design in which the slide fasteners 3A to 3D are not visible to passengers.

[0048] [Second embodiment] The roof lining 1 of the second embodiment is a modified example of the roof lining 1 of the first embodiment, and differs from the first embodiment in the details of the divided end portions 261 of the divided pieces 26A to 26D. Below, the divided end portions 261 of the divided pieces 26A, 26B connected by the slide fastener 3A will be described as a representative with reference to Figures 4 and 5.

[0049] In this embodiment, at least a portion of the base 24 is removed from each divided end 261 of the divided pieces 26A and 26B. For example, as shown in FIG. 4, at each divided end 261 of the divided pieces 26A and 26B, the urethane layer 241 of the base 24 may be removed, and a first glass fiber layer 242, a second glass fiber layer 243, and a skin material 25 may be laminated. 5, the entire base portion 24 may be removed from each divided end portion 261 of the divided pieces 26A, 26B. In this case, the divided end portion 261 has only the skin material 25.

[0050] 4 and 5, a notch 27 that opens to one side in the +Z direction and one side in the Y direction is formed in each divided end 261 of the divided pieces 26A, 26B. The range of the divided end 261 in the Y direction (i.e., the range from which at least a portion of the base 24 is removed) is not particularly limited as long as it allows sewing of the tape portion 311.

[0051] Furthermore, in this embodiment, the tape portions 311, 321 may extend not only to the divided end portions 261 of the divided pieces 26A, 26B but also to areas other than the divided end portions 261. On the other hand, the element rows 312, 322 are preferably arranged at the divided end portions 261 of the divided pieces 26A, 26B. In other words, the element rows 312, 322 are preferably arranged within the cutout portions 27.

[0052] The same explanation as above can also be applied to the divided end portions 261 of the divided pieces 26A to 26D connected by the other slide fasteners 3B to 3D.

[0053] In this configuration, the same effects as in the first embodiment are achieved, and the operation of sewing the slide fasteners 3A to 3D to the divided pieces 26A to 26D becomes easier. Furthermore, in this embodiment, the overall rigidity of the roof lining 1 can be adjusted by appropriately adjusting the range of the base portion 24 removed from the divided end portion 261 of each of the divided pieces 26A to 26D. Furthermore, in this embodiment, the slide fasteners 3A to 3D in the roof lining 1 can be prevented from protruding to the +Z side, and therefore the appearance of the roof lining 1 can be improved.

[0054] [Third embodiment] The roof lining 1 of the third embodiment is a modified example of the roof lining 1 of the first embodiment, and differs from the first embodiment in the details of the divided end portions 261 of the divided pieces 26A to 26D. Below, the divided end portions 261 of the divided pieces 26A, 26B connected by the slide fastener 3A will be described as a representative with reference to FIG.

[0055] 6, the entire base 24 is removed from each divided end 261 of the divided pieces 26A, 26B, and the divided end 261 has only the skin material 25. Therefore, each divided end 261 of the divided pieces 26A, 26B has a notch 27 that opens to one side in the +Z direction and one side in the Y direction.

[0056] The divided end portion 261 of the divided piece 26A includes a base end region 263 connected to the main body portion 262 of the divided piece 26A (i.e., the portion of the divided piece 26A where the base portion 24 is located), and a tip end region 264 that is folded back and overlaps the base end region 263. Similarly to the divided end portion 261 of the divided piece 26A, the divided end portion 261 of the divided piece 26B includes a base end region 263 and a tip end region 264. Furthermore, the fold at the divided end 261 of the divided piece 26A and the fold at the divided end 261 of the divided piece 26A are arranged in contact with or close to each other in the Y direction.

[0057] Here, the slide fastener 3A is disposed in a tip region 264 of the divided end portion 261 of the divided pieces 26A, 26B. This slide fastener 3A may be a so-called hidden fastener. For example, the tape portion 311 of the fastener stringer 31 is folded back with the center in the width direction as a fold line. The tape portion 311 has one folded piece to which the element row 312 is attached, and the other folded piece sewn to the tip region 264 of the divided piece 26A. Similarly, the tape portion 321 of the fastener stringer 32 is folded back with the center in the width direction as a fold line. This tape portion 321 has one folded piece to which the element row 322 is attached, and the other folded piece sewn to the tip region 264 of the divided piece 26B.

[0058] The same explanation as above can also be applied to the divided end portions 261 of the divided pieces 26A to 26D connected by the other slide fasteners 3B to 3D.

[0059] In this configuration, the same effects as in the first embodiment are achieved, and the operation of sewing the slide fasteners 3A to 3D to the divided pieces 26A to 26D becomes easier. Furthermore, in this embodiment, a design can be realized in which both the slide fasteners 3A to 3D and the tip side regions 264 of the segments 26A to 26D (ie, the regions including the end faces of the segments 26A to 26D) are not visible to the passenger.

[0060] [Fourth embodiment] The roof lining 1 of the fourth embodiment is a modified example of the roof lining 1 of the first embodiment, and differs from the first embodiment in the details of the divided end portions 261 of the divided pieces 26A to 26D. Below, the divided end portion 261 of the divided pieces 26A, 26B connected by the slide fastener 3A will be described as a representative with reference to FIG.

[0061] In this embodiment, the slide fastener 3A is disposed on the skin material 25 of each divided end portion 261 of the divided pieces 26A, 26B and attached to each divided end portion 261. The divided end portions 261 of the divided pieces 26A, 26B are bent toward the +Z side together with a part of the slide fastener 3A (specifically, one end portion of both widthwise ends of the tape portion 311 opposite the element rows 312, 322). As a result, the slide fastener 3A is partially exposed on the −Z side between the divided ends 261 of the divided pieces 26A and 26B.

[0062] The same explanation as above can also be applied to the divided end portions 261 of the divided pieces 26A to 26D connected by the other slide fasteners 3B to 3D.

[0063] In this embodiment, similarly to the first embodiment, the yield rate during the manufacture of the roof lining 1 can be improved. Furthermore, in this embodiment, the slide fasteners 3A to 3D can be exposed to the space inside the vehicle body from between the divided end portions 261. This allows for a design in which the slide fasteners 3A to 3D are visible to passengers.

[0064] In this embodiment, each of the divided pieces 26A and 26B has a slit 28 that extends in the X direction along the divided end 261 and opens toward the +Z direction. This makes it easy to bend the divided pieces 26A and 26B toward the +Z side even if the bases 24 of the divided pieces 26A and 26B are thick.

[0065] [Fifth embodiment] The roof lining 1 of the fifth embodiment is a modified example of the roof lining 1 of the fourth embodiment, and differs from the fourth embodiment in the details of the divided end portions 261 of the divided pieces 26A to 26D. Below, the divided end portions 261 of the divided pieces 26A, 26B connected by the slide fastener 3A will be described as a representative with reference to FIGS.

[0066] In this embodiment, at least a portion of the base 24 is removed from each divided end 261 of the divided pieces 26A and 26B. For example, as shown in FIG. 8, at each divided end 261 of the divided pieces 26A and 26B, the urethane layer 241 of the base 24 may be removed, and a first glass fiber layer 242, a second glass fiber layer 243, and a skin material 25 may be laminated. 9, the entire base portion 24 may be removed from each divided end portion 261 of the divided pieces 26A, 26B. In this case, the divided end portion 261 has only the skin material 25.

[0067] In this embodiment, each divided end 261 of the divided pieces 26A, 26B and a part of the slide fastener 3A (specifically, one end of each of the widthwise ends of the tape portions 311, 321 opposite the element rows 312, 322) are bent toward the +Z side, as in the fourth embodiment. As a result, the slide fastener 3A is partially exposed to the -Z side from between the divided end portions 261 of the divided pieces 26A, 26B.

[0068] The same explanation as above can also be applied to the divided end portions 261 of the divided pieces 26A to 26D connected by the other slide fasteners 3B to 3D.

[0069] In this embodiment, similar to the first embodiment, it is possible to improve the yield rate during the manufacture of the roof lining 1. Also, similar to the fourth embodiment, it is possible to realize a design in which the slide fasteners 3A to 3D are visible to passengers. Furthermore, it becomes easier to sew the slide fasteners 3A to 3D to the divided pieces 26A to 26D.

[0072] In each of the above embodiments, the positions of the slide fasteners 3A to 3D can be changed as desired as long as they are positioned so as to traverse from the opening 21 of the lining material 2 to the outer edge 23 of the lining material 2. For example, the slide fasteners 3A to 3D may be arranged along other directions, such as the Y direction, instead of the X direction.

[0073] In addition, in each of the above embodiments, the two slide fasteners 3A, 3B (or 3C, 3D) are arranged on one parting line L1 (or L2), but the present invention is not limited to this. For example, the slide fasteners 3A to 3D may be arranged on different parting lines.

[0074] In each of the above embodiments, the element rows 312, 322 are arranged on the +Z side surface of the tape portions 311, 321, but may also be arranged on the -Z side surface of the tape portions 311, 321. In this case, in the above fourth and fifth embodiments, the element rows 312, 322 of the slide fastener 3A may be exposed on the -Z side from between the divided ends 261 of the divided pieces 26A, 26B.

[0075] In addition, in each of the above embodiments, the slide fasteners 3A to 3D are coil fasteners, but the present invention is not limited to this. For example, the slide fasteners 3A to 3D may be metal fasteners in which the element rows 312, 322 are made of metal, or resin fasteners in which the element rows 312, 322 are injection-molded.

[0076] In each of the above embodiments, the slide fasteners 3A to 3D include tape portions 311, 321 and element rows 312, 322, but the present invention is not limited to this. For example, in the above second embodiment, the slide fasteners 3A to 3D may have element rows 312, 322 attached directly to the divided end portions 261 of the divided pieces 26A to 26D.

[0077] In each of the above embodiments, the slide fasteners 3A to 3D are attached to the divided pieces 26A to 26D by sewing, but the present invention is not limited to this, and they may be attached using an adhesive or the like. [Explanation of symbols]
