Description

Technical Field

[0001] The present invention relates to a sheet material fixing tool and an assembling method for fixing adjacent sheet material components to each other in a car seat or the like. Background Art

[0002] Many parts of automobile seats (automobile seats) etc. have sheet members such as cover members or surface materials covering the surface of a cushion body formed of synthetic resin foam material. The edges (sheet edges) of these sheet members are fixed to each other by sheet fixing members described in Document 1 (Japanese Patent No. 7191490) or Document 2 (Japanese Patent No. 5514901).

[0003] The sheet material fixing device described in Document 1 includes: a first fixing member fixed to the edge of the first sheet material; and a second fixing member fixed to the edge of the second sheet material, and the first fixing member and the second fixing member are mutually engaged. In the sheet material fixing device, when the second fixing member is engaged with the first fixing member, the fixing portion of the second fixing member fixed to the second sheet material is arranged at a position closer to the first sheet material side than the portion where the first fixing member and the second fixing member are engaged with each other, thereby both the first fixing member and the second fixing member are covered by the first sheet material and the second sheet material, and the sheet material fixing device is not exposed to the outside.

[0004] In addition, the sheet material fixing device described in Document 2 includes: a first component to which one sheet material edge is fixed; and a second component to which the other sheet material edge is fixed, and the first component and the second component are engaged with each other. In the sheet material fixing device, when the first component and the second component are engaged, the fixed portion of the other sheet material edge fixed to the second component is arranged at a position closer to the one sheet material edge side than the first component and the second component, thereby, both the first component and the second component are covered by the one sheet material edge and the other sheet material edge, and the sheet material fixing device is not exposed to the outside.

[0005] However, the sheet fixing tool is generally a component that is arranged so as to be covered by the edge portions of a pair of sheet members and not exposed to the outside, as in the sheet fixing tools described in the aforementioned documents 1 and 2, and is not a component structure that actively exposes to the outside.

[0006] However, for example, when it is desired to add decoration to the portion between the edges of a pair of sheet members, the sheet fixing tools described in Documents 1 and 2 that are not exposed to the outside are not suitable for this purpose. Summary of the invention

[0007] An object of the present invention is to provide a sheet material fixing device and an assembling method capable of adding decoration between a pair of sheet material members.

[0008] (1) The sheet material fixing device of the present invention is in the shape of an elongated strip and is used to fix the second sheet material component to the first sheet material component. The sheet material fixing device includes: a female component, which is fixed to the first sheet material component; and a male component, which is fixed to the second sheet material component. The female component includes: a main body sheet; and a snap-fitting portion, which is formed on the inner side of the main body sheet in a manner capable of snapping with the male component. When the male component is snapped with the snap-fitting portion, the main body sheet is configured in a manner covering at least a portion of the male component from the outside, and is exposed to the outside relative to the first sheet material component and the second sheet material component between the fixed positions where the first sheet material component and the second sheet material component are respectively fixed.

[0009] According to the sheet material fixing device of the present invention, the second sheet material is fixed to the first sheet material by engaging the male part with the engaging part of the female part, and the main body sheet of the female part is arranged in a manner to cover at least a part of the male part in the engaged state, and at least a part of the female part is exposed to the outside relative to the first sheet material and the second sheet material between the aforementioned fixed positions. Therefore, an additional decorative part can be formed at least on the exposed main body sheet, thereby adding decoration between the first sheet material and the second sheet material.

[0010] Furthermore, since there is no need to use any parts other than the sheet fixing member to add decoration, the possibility of increased cost or complicated assembly caused by adding other parts can be eliminated.

[0011] (2) In one embodiment of the sheet fastener of the present invention, the main sheet portion may include: a fixing portion fixed to the first sheet member; and an extension portion extending continuously from the fixing portion, wherein the extension portion has a storage space for storing a part of the male member on the inner side opposite to the surface exposed to the outside, and the engaging portion is formed in the storage space.

[0012] According to such a configuration, at least a portion of the male member engaged with the engaging portion formed in the storage space is covered from the outside by the extending portion, and the extending portion serves as an additional decorative portion, thereby adding decoration between the first sheet member and the second sheet member.

[0013] (3) In the sheet material fixing tool according to one aspect of the present invention, at least a portion of an outer surface of the extending portion may be curved.

[0014] According to such a structure, compared with the case where the part connected to the fixing part is in an angular shape such as a U-shape, the hand feel is better, and the flexibility of the sheet fastener itself can be improved. Even if the fixing part is in a curved shape, the sheet fastener can be easily bent and deformed for fixing, thereby eliminating the need to form multiple gaps along the width direction orthogonal to its length direction in order to improve the flexibility of the sheet fastener.

[0015] (4) In one embodiment of the sheet fastener of the present invention, the engaging portion may include an engaging sheet portion protruding from the inner side of the extending portion toward the storage space, and the extending portion may include a protruding portion extending toward the fixed position side where the second sheet member is fixed compared to a portion connected to the engaging portion, and the top end of the protruding portion abuts against the second sheet member in the engaged state.

[0016] According to such a configuration, the tip of the protruding portion abuts against the second sheet member when the female member and the male member are engaged, so that the male member can be largely covered by the extending portion, thereby improving the design.

[0017] In addition, the engagement state between the female member and the male member can be stabilized by the tip of the protruding portion contacting the second sheet member.

[0018] (5) In one aspect of the sheet material fixing device of the present invention, the engaging portion may include an engaging piece portion protruding from the inner side of the extending portion toward the storage space, the male component may include an engaged portion engaged with the top end of the engaging piece portion, and a receiving portion may be formed on the fixing portion, the receiving portion being connected to a portion of the fixing portion on an opposite side of a portion connected to the extending portion, and the receiving portion may receive the male component in the engaged state on a side opposite to the engaged portion.

[0019] According to such a configuration, the male member is received by the receiving portion and inserted into the female member, whereby the engaging piece is temporarily bent and deformed, so that the engaged portion of the male member can be easily engaged with the tip of the engaging piece.

[0020] On the other hand, in the engaged state, the engaging piece can function as a "barb" to prevent the male component from being pulled out of the female component. Even if the male component is to be pulled out of the female component, a force can be applied to the engaging piece to bring its top end closer to the male component, thereby narrowing the gap between the engaging piece and the receiving portion, which can further improve the engaging strength.

[0021] (6) In one embodiment of the sheet material fixing device of the present invention, the engaging portion may include: an engaging piece portion protruding from the inner side of the extending portion; and an engaging protrusion portion connected to the fixing portion and arranged at a position facing the engaging piece portion, and the male component has a pair of engaged portions respectively engaging with the engaging piece portion and the engaging protrusion portion.

[0022] According to such a configuration, since the pair of engaged portions of the male member engage with the engaging piece portion and the engaging protrusion, the engagement strength can be improved.

[0023] (7) In one aspect of the sheet material fixing device of the present invention, the male component may include: a long strip-shaped male component body having an engaged portion engaged with the engaging portion and having flexibility; and a belt component installed on the male component body, wherein, except for the engaged portion, the thickness dimension of the male component body in the thickness direction orthogonal to the length direction is set to be smaller than the width dimension of the male component body in the width direction orthogonal to the length direction and the thickness direction.

[0024] According to such a structure, the male part body can be formed into a substantially flat shape, and for example, even if the male part body is formed of a hard resin or the like, it can be made flexible. In addition, since the belt member is attached to the male part body, the belt member can be easily fixed to the second sheet member from the front side by sewing or the like. In addition, by folding back the portion of the second sheet member to which the belt member is fixed, it is possible to eliminate the situation where the fixed belt member is exposed on the front side.

[0025] (8) In the sheet material fixing tool according to one aspect of the present invention, the female member may be formed of a material softer than that of the male member.

[0026] According to such a configuration, the engagement strength between the male member and the engagement portion can be maintained, and the flexibility of the entire sheet material fixing tool can be improved by forming the female member with a soft material.

[0027] (9) The assembly method of the present invention is used to fix the second sheet component to the first sheet component by means of a long sheet fixing part. In the assembly method, the sheet fixing part includes a female part and a male part, the female part has a main sheet and a snap-fitting part formed on the inner side of the main sheet, the male part can snap-fit ​​with the snap-fitting part, the female part is fixed to the first sheet component and the male part is fixed to the second sheet component, the male part is snap-fitted with the snap-fitting part, and in the snap-fitting state where the male part is snap-fitted with the snap-fitting part, the main sheet is configured to cover at least a portion of the male part from the outside, and is configured to be exposed to the outside relative to the first sheet component and the second sheet component between the fixed positions where the first sheet component and the second sheet component are respectively fixed.

[0028] According to the assembling method of the present invention, it is possible to provide the sheet material fixing tool of the present invention which can exert the above-mentioned effects and the assembling method which can exert the same effects.

[0029] According to the present invention, it is possible to provide a sheet material fixing device and an assembling method capable of adding decoration between a pair of sheet material members. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] (Structure of this embodiment)

[0037] Hereinafter, embodiments of the present invention will be described based on the drawings.

[0038] exist Figure 1 and Figure 2In the embodiment, the sheet material fixing part 10 is used to fix the surface material 5 (board surface material) covering the back plate 4 of the automobile seat 1 to the surface material 3 (main surface material) as the first sheet material component, and the surface material 3 covers the seat body 2 of the automobile seat 1 as a seat for an automobile vehicle. The sheet material fixing part 10 includes: a male part 20 (inner part), which is fixed to the edge part 5A of the surface material 5; and a female part 30 (outer part), which is fixed along the edge part 3A of the surface material 3. In addition, the back plate 4 in this embodiment is formed of a soft back plate that is more flexible than the usual type of seat back material, and is another component separated from the seat body 2.

[0039] In the following description, the length direction (front-back direction) of the sheet fixing member 10 is defined as the X-axis direction, the width direction (left-right direction) of the sheet fixing member 10 is defined as the Y-axis direction, and the thickness direction (front-back direction) of the sheet fixing member 10 is defined as the Z-axis direction. The X-, Y-, and Z-axis directions are orthogonal to each other.

[0040] The male component 20 and the female component 30 are each formed continuously along the X-axis direction in the same manner as the cross-sectional shape in the plane perpendicular to the X-axis direction, for example, multiple intermittent gaps along the Y-axis direction are not formed. In addition, the female component 30 is formed of a material softer than the male component 20. Of course, the male component 20 and the female component 30 can also be formed of the same material, and the male component 20 can also be formed of a material softer than the female component 30.

[0041] like Figure 2 and Figure 3 As shown, the male part 20 includes: a male part body 21, which is flexible (Japanese: flexibilization) and is long in the X-axis direction; and a belt part 26, which is attached to the male part body 21, is flexible, and is long in the X-axis direction. As the belt part 26, any flexible member can be used, and nonwoven fabric is used in this embodiment.

[0042] The male component body 21 includes: a clamped portion 22, which is configured to protrude toward the extension portion 33 side described later when the male component 20 is clamped with the female component 30; a slope 23, which is inclined from the top end of the male component body 21 to the clamped portion 22; and a receiving surface 24, which is connected to the slope 23 at the top end of the male component body 21 and is formed along the Y-axis direction in the clamped state. In this embodiment, the receiving surface 24 has a flat surface along the surface of the belt member 26. In addition, a groove 25 is formed in the male component body 21, which is open at its rear end side (the surface material 5 side) and is fixed to the belt member 26. The thickness dimension of the male component body 21 in the Z-axis direction is set to be smaller than the width dimension in the Y-axis direction, except for the clamped portion 22, so that in this embodiment, the male component body 21 is a flat and easily bendable overall shape in the Y-axis direction.

[0043] The belt member 26 includes a fixing portion 261 that is fixed in a state of being inserted into the groove portion 25 formed in the male member body 21, and an extension portion 262 that is connected to the fixing portion 261 and extends from the rear end side (the surface material 5 side) of the male member body 21. The belt member 26 is fixed at the fixing position P2 by sewing a portion of the extension portion 262 that is separated from the male member body 21 by a predetermined interval along the edge portion 5A of the surface material 5.

[0044] like Figure 2 and Figure 4 As shown, the female component 30 includes: a main body sheet 31, which is configured to cover at least a portion of the male component 20 in the engaged state from the outside (the surface side of the surface material 3, 5), and in this embodiment, covers the male component body 21 and a portion of the belt component 26; and a locking portion 40, which is formed on the inner side of the main body sheet 31 (the back side of the surface material 3, 5).

[0045] The main body piece 31 includes: a fixing portion 32, which is fixed at a fixed position P1 by sewing along the edge portion 3A of the surface material 3; an extension portion 33, whose cross-section is curved and extends continuously from the fixing portion 32; and a receiving portion 35, which is connected to the fixing portion 32 and receives the received surface 24 of the male component 20, and a snap-fit ​​portion 40 is provided on the inner side of the extension portion 33.

[0046] The extension portion 33 is formed into an arc shape by bending in a manner protruding outward in the Z-axis direction, and its base end 331 is connected to the fixing portion 32. On the side of the top end 332 of the extension portion 33, there is a protrusion 34 that is arranged at a position closer to the surface material 5 than the portion connected to the locking portion 40 in the engaged state. In the extension portion 33 formed in this way, at least a portion of its outer surface is curved, and a storage space 330 for storing at least a portion of the male component 20 is formed on the side opposite to the surface exposed to the outside, that is, on the inner side. The locking portion 40 is formed in the storage space 330. The extension portion 33 is a structure that is arranged on the surface side relative to the fixing portion 32 in the engaged state. In addition, in the present embodiment, the fixing portion 32 is formed by a portion that is flat and slightly extended from the base end 331 of the extension portion 33, but is not limited to this shape, for example, it can also be formed in a curved shape along the curved shape of the extension portion 33.

[0047] The protrusion 34 is formed by extending in a forked manner from the portion connected to the engaging portion 40, and is configured to extend toward the surface material 5 side compared to the connected portion when the male component 20 and the female component 30 are engaged as described above, and its top end 332 abuts against the surface 5B of the surface material 5. In addition, the protrusion 34 also constitutes a part of the extension portion 33, and the cross-section is curved. In addition, a guide protrusion 341 protruding inward is formed at the top end 332 of the protrusion 34, and the guide protrusion 341 guides the inclined surface 23 (refer to FIG. 2 ) of the male component 20 when the male component 20 is inserted into the female component 30. Figure 3 ) is guided toward the fixing portion 32 side.

[0048] The receiving portion 35 is connected to the opposite side portion of the portion where the fixing portion 32 and the extension portion 33 are connected relative to the fixing portion 32. The receiving portion 35 extends from the fixing portion 32 side toward the top end 332 side. In addition, the receiving portion 35 protrudes in the direction of the protruding portion 34, and is arranged at a position lower than the lower end position of the protruding portion 34 in the Z-axis direction. An entrance to the storage space 330 is formed between the receiving portion 35 and the protruding portion 34, and the entrance is an opening narrower than the inside of the storage space 330. In addition, the receiving portion 35 is arranged along the Y-axis direction in the engaged state and is arranged opposite to the extension portion 33 in the front and back direction of the sheet fixing member 10 (in the Z-axis direction in the present embodiment), and receives the male component 20 in the engaged state on the side opposite to the engaged portion 22 in the Z-axis direction.

[0049] The engaging portion 40 has an engaging piece 41 protruding from the inner side of the extension portion 33 toward the storage space 330. In the present embodiment, the engaging piece 41 protrudes obliquely from the inner side of the extension portion 33 toward the receiving portion 35 side or the fixing portion 32 side and engages with the engaged portion 22 of the male component 20 at the top end 411. The top end of the engaging piece 41 is arranged at a position closer to the fixing portion 32 side than the top end of the receiving portion 35. The engaging piece 41 has a certain degree of flexibility because it is formed integrally with the extension portion 33. Therefore, when the male component 20 is inserted into the female component 30, the engaging piece 41 is pressed by the engaged portion 22 and slightly bent, so that the interval between the engaging piece 41 and the receiving portion 35 is expanded, and the male component 20 is easily inserted. On the other hand, when a pulling force is applied to the male component 20 when the top end 411 of the engaging piece 41 is engaged with the engaged portion 22 of the male component 20, the engaging piece 41 bends so that the interval between it and the receiving portion 35 becomes narrower, thereby further deeply engaging the engaging piece 41 and the engaged portion 22 (the engaging margin between the engaging piece 41 and the engaged portion 22 is increased), which can further improve the engaging strength.

[0050] (Assembly steps)

[0051] The above-described assembly procedure of fixing the surface material 5 to the surface material 3 by the sheet material fixing tool 10 will be described.

[0052] First, if Figure 4 As shown, the fixing portion 32 of the mother member 30 is fixed to the edge portion 3A of the surface material 3 at the fixing position P1 by sewing from the surface 3B. Figure 3 As shown, the extended portion 262 of the belt member 26 of the male member 20 is fixed to the edge portion 5A of the surface material 5 at the fixing position P2 by sewing from the surface 5B side.

[0053] Here, since the male component 20 is continuously formed in the same manner as its cross-sectional shape in the X-axis direction, and the female component 30 is continuously formed in the same manner as its cross-sectional shape in the X-axis direction, even if the engaging positions of the male component 20 and the female component 30 deviate to a certain extent in the X-axis direction, poor engagement will not occur, thereby eliminating the need to align the male component 20 and the female component 30 with each other when they are manufactured or sewn to the surface materials 3, 5.

[0054] Therefore, even if the male component 20 is manufactured or sewn to the surface material 5 in a certain factory and the female component 30 is manufactured or sewn to the surface material 3 in another factory different from the factory, the male component 20 and the female component 30 can be properly engaged with each other. Therefore, in the sheet fastener 10 of the present embodiment, for example, when a slide fastener having a plurality of chain elements (engaging components) connected along the X-axis direction is used, poor engagement due to positional deviation (pitch deviation) of the left and right chain elements in the X-axis direction will not occur.

[0055] In addition, in the sheet fastener 10 of the present embodiment, the male component 20 or the female component 30 is not provided with a gap extending in a direction orthogonal to the X-axis direction, but is formed continuously in the X-axis direction. Therefore, for example, compared with the aforementioned case where a gap is provided, the effort required to engage the male component 20 with the female component 30 can be reduced.

[0056] In addition, when the edge portion 5A of the surface material 5 is not folded back, the extended portion 262 of the belt part 26 of the male part 20 is arranged on the end edge 511 side of the edge portion 5A of the surface material 5 relative to the male part main body 21, and the engaged portion 22 of the male part main body 21 is arranged at a position closer to the surface 5B side of the surface material 5 than the fixed portion 261 of the belt part 26.

[0057] Then, if Figure 5 As shown, the surface material 5 is set at a predetermined position covering the seat body 2, and the edge 3A of the surface material 3 is folded back to the back side 3C thereof while the mother member 30 is tilted from the surface 3B side. Figure 5 As shown, the surface material 5 is arranged at a position opposite to the fixed position P1 of the female component 30 relative to the surface material 3, the edge portion 5A of the extended portion 262 fixed with the belt component 26 is folded back to the back side 5C of the surface material 5, and the male component main body 21 is arranged at a position closer to the surface material 3 side than the surface material 5, and the engaged portion 22 of the male component main body 21 is arranged at a position closer to the outside than the fixed portion 261 of the belt component 26 in the Z-axis direction.

[0058] Next, the male component body 21 is inserted between the top end 332 of the female component 30 and the receiving portion 35. At this time, the engaged portion 22 is arranged at a position facing the extension portion 33 in the X-axis direction. Furthermore, the inclined surface 23 of the male component body 21 is guided by the engaging piece 41, and the male component 20 is inserted into the female component 30 until the engaged portion 22 is located at a position closer to the fixing portion 32 side (the surface material 3 side) than the engaging piece 41, so that the engaged portion 22 is engaged with the engaging piece 41. At this time, the engaging surface of the top end 411 of the engaging piece 41 and the engaged surface of the engaged portion 22 of the male component 20 are arranged along the Z-axis direction. Since the received surface 24 of the male component body 21 in a state of being engaged with each other in an inseparable manner in the Y-axis direction is blocked by the receiving portion 35 of the female component 30, the engaged state of the engaged portion 22 and the engaging piece 41 can be maintained.

[0059] In this engaged state, in the present embodiment, the respective fixed positions P1 and P2 of the surface materials 3 and 5 are arranged facing each other in the Y-axis direction, the female component 30 is arranged between the surface materials 3 and 5, and the engaging portion 40 is arranged at a position closer to the fixed position P2 side than the fixed position P1. The extension portion 33 of the female component 30 arranged in this way covers the entire male component body 21 and the portion of the extended portion 262 of the belt component 26 that is not sewn to the edge portion 5A of the surface material 5 from the outside in the Z-axis direction, and is arranged in a manner exposed to the outside relative to the surface materials 3 and 5 between the fixed positions P1 and P2 of the surface materials 3 and 5, respectively, and the male component body 21 is completely stored in the storage space 330. In addition, the portion of the extended portion 262 that is sewn to the edge portion 5A that is closer to the edge side than the fixed position P2 is folded back to the back surface 5C side of the surface material 5, so that it is not exposed to the surface 5B side. Furthermore, in the engaged state, the top end 332 of the extension portion 33 of the female component 30 is arranged in contact with or capable of contacting the surface 5B of the surface material 5, and the receiving portion 35 is arranged opposite to the extension portion 33 located outside in the Z-axis direction. In addition, the sheet material fixing member 10 is configured in a manner that a plurality of spaces can be formed between the main sheet portion 31 and the male component 20 in the aforementioned engaged state, thereby making it easy to insert and engage the male component 20 in the female component 30.

[0060] In this way, the sheet fixing member 10 is assembled, and the skin material 5 is fixed to the skin material 3. In the fixed state, only the extension portion 33 in the female part 30 of the sheet fixing member 10 is exposed to the outside between the skin materials 3 and 5, so at least any color, coating or lamination is applied to the extension portion 33, thereby making it easy to add decoration between the skin materials 3 and 5. In addition, even in the case where lamination is applied to the extension portion 33 as described above, the extension portion 33 itself is exposed to the outside. In addition, since the female part 30 that allows a certain degree of positional deviation in the X-axis direction relative to the male part 20 does not need to be aligned and sewn to the skin materials 3 and 5 in the same factory as the male part 20, a plurality of female parts 30 with various additional decorations can be manufactured and sewn in other factories different from the factory that manufactures and sews the male part 20, so the female part 30 to be used can be selected from a plurality of female parts 30, and the types of additional decorations between the skin materials 3 and 5 can be increased.

[0061] (Variation Example)

[0062] In the embodiment, the female component 30 of the sheet fixing member 10 includes a snap-fitting sheet 41 and a receiving portion 35, the snap-fitting sheet 41 is snap-fitted with the received portion 22 of the male component body 21 of the single claw shape, and the receiving portion 35 receives the received surface 24 of the male component body 21, but is not limited thereto. For example, Figure 6 As shown in the modified example of FIG. 1 , a female member 30B that engages with a two-claw-shaped male member main body 21B is formed in the sheet material fixing tool 10B.

[0063] The male member main body 21B has a pair of engaged portions 22B which are arranged to face each other in the Z-axis direction with the fixing portion 261 of the belt member 26 disposed in between, and are formed in a substantially arrow shape.

[0064] The female part 30B has an engagement protrusion 36 instead of the aforementioned receiving portion 35 connected to the fixing portion 32, and the engagement protrusion 36 faces the engagement piece 41 connected to the inner side of the extension portion 33. The engagement protrusion 36 is formed at the top end of the piece 37 extending continuously from the fixing portion 32 so as to protrude toward the engagement piece 41 side.

[0065] In the sheet fastener 10B, the male component body 21B is inserted into the female component 30B, and the pair of engaged portions 22B engage with the engaging piece 41 and the engaging protrusion 36 of the female component 30B, whereby the male component 20B having the male component body 21B and the female component 30B are in an engaged state.

[0066] In the embodiment, the male component 20 and the female component 30 are each formed continuously in the length direction in the same manner as the cross-sectional shape, but for example, a plurality of gaps extending in a direction orthogonal to the X-axis direction may be formed in one or both of the male component 20 and the female component 30.

[0067] In the embodiment, the cross-section of the extension portion 33 is formed into a curved shape, but is not limited to this. As long as the main body sheet 31 is exposed to the outside between the surface materials 3 and 5, the shape of the extension portion 33 can be appropriately changed according to the required design to form, for example, a square shape, a combination of a square shape and a curved shape, etc.

[0068] In the above embodiment, the engagement portion 40 is formed inside the extension portion 33 , but the present invention is not limited thereto. Any position is acceptable as long as it can be engaged with the male member 20 . The engagement portion 40 may be formed at a position different from the extension portion 33 .

[0069] In the above-described embodiment, the extension portion 33 has the protrusion 34 configured to extend toward the surface material 5 side from the portion connected to the engagement portion 40 in the engaged state, but the present invention is not limited thereto. For example, the protrusion 34 may be omitted when the portion of the extension portion 33 closer to the top end than the portion connected to the engagement portion 40 does not need to cover the male component 20. In this case, the top end 332 of the extension portion 33 is configured at a position that does not abut against the surface material 5. In addition, even when the extension portion 33 has the protrusion 34, the top end 332 may be configured at a position that does not abut against the surface material 5.

[0070] In the embodiment, the snap-fitting portion 40 has a snap-fitting piece 41 that protrudes obliquely from the inner side of the extension portion 33 toward the fixing portion 32 side, but is not limited to this. For example, even if it is a snap-fitting piece that protrudes from the inner side of the extension portion 33 along the Z-axis direction, as long as it is a structure that can be snapped with the snap-fitting portion 22 of the male component 20.

[0071] In the embodiment, the thickness dimension of the male component body 21 is set to be smaller than the width dimension as mentioned above, and is arranged flat in the Y-axis direction in the engaged state, but is not limited to this. As long as it is a structure that can be engaged with the female component 30, the male component body 21 can also be constructed with a dimensional relationship different from the above-mentioned dimensional relationship.

[0072] In the above embodiment, the belt member 26 of the male member 20 is formed of nonwoven fabric, but the present invention is not limited thereto and any structure may be used as long as it has flexibility as described above, for example, it may be a woven fabric or a bendable sheet.

[0073] In the above embodiment, the female component 30 is made of a material softer than the male component 20, but the invention is not limited thereto. For example, the female component 30 may be made of the same material as the male component 20, or the male component 20 may be made of a material softer than the female component.

[0074] In the above embodiment, the male component 20 and the female component 30 are fixed to the surface materials 3 and 5 by sewing, respectively, but the present invention is not limited thereto, and any method may be used as long as sufficient fixing strength can be obtained, for example, fixing by bonding or the like.

[0075] In the embodiment, the structure in which the female component 30 is fixed to the surface material 3 and the male component 20 is fixed to the surface material 5 is described, but the opposite may be true, where the female component 30 is fixed to the surface material 5 and the male component 20 is fixed to the surface material 3. In this case, the surface material 5 is equivalent to the first sheet component and the surface material 3 is equivalent to the second sheet component.

[0076] In the embodiment, the sheet fixing part 10 is described as a component for connecting the surface materials 3 and 5 of the sheet cover of the automobile seat 1, but in addition to this, it can also be a component for connecting sheet parts such as seats for airplanes or ships, seats used in schools or office buildings, sports equipment, furniture such as sofas or beds for residences, bags, clothing, tents and other erected objects, and transport packaging.

[0077] (Effects of this embodiment)

[0078] (1) The sheet material fixing member 10, 10B of the present embodiment is in the form of a strip and is used to fix the surface material 5 to the surface material 3, and includes: a female component 30, 30B, which is fixed to the surface material 3; and a male component 20, 20B, which is fixed to the surface material 5. The female component 30, 30B includes: a main body sheet 31; and an engaging portion 40, which is formed on the inner side of the main body sheet 31 in a manner that can be engaged with the male component 20, 20B. The main body sheet 31 is configured to cover at least a portion of the male component 20, 20B from the outside, and at least a portion of the female component 30, 30B is exposed to the outside relative to the surface material 3, 5 between the fixing positions P1, P2 of the surface material 3, 5, respectively. Thus, the surface material 5 is fixed to the surface material 3 by the engagement of the engagement portion 40 of the male component 20, 20B and the female component 30, 30B, and at this time, it is arranged in a manner to cover at least a portion of the male component 20, 20B in the engaged state, and is exposed to the outside relative to the surface material 3, 5 between the aforementioned fixing positions P1, P2. Therefore, at least a portion of the main body sheet 31 can be used as an additional decorative component between the surface material 3 and the surface material 5. In addition, since it is not necessary to use components other than the sheet material fixing parts 10, 10B for additional decoration, the possibility of increased costs or troublesome assembly due to the addition of other components can be eliminated.

[0079] (2) The main body sheet 31 includes: a fixing portion 32 fixed to the surface material 3; and an extension portion 33 extending continuously from the fixing portion 32, and the extension portion 33 has a storage space 330 for storing a part of the male component 20, 20B formed on the inner side of the extension portion 33, which is the side opposite to the surface exposed to the outside, and the engaging portion 40 is formed in the storage space 330. Therefore, at least a part of the male component 20, 20B engaged with the engaging portion 40 formed in the storage space 330 is covered from the outside by the extension portion 33, and the extension portion 33 can be used as a decoration between the surface material 3 and the surface material 5.

[0080] (3) At least a portion of the outer surface of the extension portion 33 is curved. Therefore, compared with the case where the portion connected to the fixing portion 32 is angular, such as a U-shape, the flexibility of the sheet fixing member itself can be improved, and even if the fixing portion is curved, the sheet fixing member 10, 10B can be easily bent and deformed for fixing, and the need to form a plurality of slits along the Y-axis direction in order to improve the flexibility of the sheet fixing member 10, 10 can be eliminated.

[0081] (4) The engaging portion 40 has an engaging piece 41 protruding from the inner side of the extension portion 33 toward the storage space 330, and the extension portion 33 has a protrusion 34 extending toward the fixed position P2 side of the surface material 5 compared to the portion connected to the engaging portion 40, and the top 332 of the protrusion 34 abuts against the surface material 5 in the engaged state. Therefore, when the female component 30, 30B and the male component 20, 20B are engaged, the top 332 of the protrusion 34 abuts against the surface material 5, thereby allowing the male component 20, 20B to be covered more by the extension portion 33, for example, even if no additional decoration is applied to the male component 20, 20B, the appearance design can be improved. In addition, by the top 332 of the protrusion 34 abutting against the surface material 5, the engaging state of the female component 30, 30B and the male component 20, 20B can be stabilized.

[0082] (5) The engaging portion 40 has an engaging piece 41 protruding from the inner side of the extension portion 33 toward the storage space 330, and the male component 20 has an engaged portion 22 engaged with the top end 411 of the engaging piece 41. The fixed portion 32 is provided with a receiving portion 35 connected to the opposite side of the portion of the fixed portion 32 connected to the extension portion 33, and the receiving portion 35 receives the male component 20 in the engaged state on the side opposite to the engaged portion 22. Therefore, when the male component 20 is inserted into the female component 30 while being received by the receiving portion 35, the engaging piece 41 is temporarily bent and deformed, so that the engaged portion 22 of the male component 20 can be easily engaged with the top end 411 of the engaging piece 41. On the other hand, in the engaged state, the engaging piece 41 can function as a "barb" to prevent the male component 20 from being pulled out of the female component 30. Even if the male component 20 is to be pulled out of the female component 30, a force will be applied to the engaging piece 41 to bring its top end 411 closer to the male component 20, thereby narrowing the gap between the engaging piece 41 and the receiving portion 35, which can further improve the engaging strength.

[0083] (6) In this embodiment Figure 6 In the sheet material fixing device 10B according to the modified example shown, the engaging portion 40 includes an engaging piece 41 protruding from the inner side of the extending portion 33 and an engaging protrusion 36 connected to the fixing portion 32 and arranged at a position facing the engaging piece 41, and the male component 20B has a pair of engaged portions 22B respectively engaged with the engaging piece 41 and the engaging protrusion 36. Therefore, since the pair of engaged portions 22B of the male component 20B engage with the engaging piece 41 and the engaging protrusion 36, the engagement strength can be improved.

[0084] (7) The male part 20, 20B includes: a male part body 21, 21B, which is in a long strip shape, has flexibility, and has a clamped part 22, 22B that is clamped with the clamping part 40; and a belt part 26, which is installed on the male part body 21, 21B, and the male part body 21, 21B, except for its clamped part 22, 22B, is set to have a thickness dimension in the Z-axis direction that is smaller than the width dimension of the male part body 21, 21B in the Y-axis direction. Therefore, the male part body 21, 21B can be formed into a substantially flat shape, for example, even if the male part body 21, 21B is formed of a hard resin, it can be flexible. In addition, since the belt part 26 is installed on the male part body 21, 21B, the belt part 26 can be easily fixed to the surface material 5 from the surface side (surface 5B side) by sewing or the like. Furthermore, by folding back the portion of the surface material 5 to which the tape member 26 is fixed, it is possible to prevent the fixed tape member 26 from being exposed on the front side.

[0085] (8) The female parts 30 and 30B are made of a softer material than the male parts 20 and 20B. Therefore, the engagement strength between the male parts 20 and 20B and the engagement portion 40 can be maintained, and the overall flexibility of the sheet material fastener 10 and 10B can be improved by making the female parts 30 and 30B of a softer material.

[0086] (9) The assembly method of this embodiment is used to fix the surface material 5 to the surface material 3 by means of a long sheet fixing part 10, 10B. In the assembly method, the sheet fixing part 10, 10B includes: a female part 30, 30B, which has a main sheet portion 31 and a snap-fitting portion 40 formed on the inner side of the main sheet portion 31; and a male part 20, 20B, which can snap-fit ​​with the snap-fitting portion 40 to fix the female part 30, 30B to the surface material 3 and the male part 20, 20B to the surface material 5, so that the male part 20, 20B snaps with the snap-fitting portion 40. In the snap-fitting state in which the male part 20, 20B snaps with the snap-fitting portion 40, the main sheet portion 31 is configured in a manner to cover at least a portion of the male part 20, 20B from the outside, and is configured in a manner to be exposed to the outside relative to the surface materials 3, 5 between the fixing positions P1, P2 of the surface materials 3, 5, respectively. Therefore, it is possible to provide an assembling method that can achieve the same effects as those of the sheet material fixing tool 10 or 10B according to the present embodiment described above.
