Description

Technical Field

[0001] The present invention relates to a fastening component and fastening method for locking and holding a skin component in a buffer body. Background Technology

[0002] For example, Japanese Patent Application Publication No. 2016-88365 (Patent Document 1) discloses a vehicle seat in which the outer skin component (seat cover) is inlaid and fixed to a buffer body (seat cushion). The vehicle seat of Patent Document 1 includes: an inlay component installed on the outer skin component; and a clamping component fixed to the buffer body.

[0003] The insert has a non-woven fabric strip (fabric body) and a synthetic resin anchoring part (columnar body) installed on the side edge of the strip. The cross-section of the anchoring part is shaped like a spike. The clamping member has a flat base (foot piece), a pair of arms that bend and stand upright from the base, and a pair of claw pieces provided at the front end of each arm. The pair of arms are elastically deformable. The pair of claw pieces are configured such that, after the anchoring part is inserted into the arm, it is engaged with the anchoring part housed within the arm by the elastic return of the arm.

[0004] In the vehicle seat described in Patent Document 1, the insert, which is mounted on the surface component, is inserted into and locked into a clamping component fixed to the buffer body, thereby securing the insert to the clamping component. As a result, the surface component is pulled in by the insert and locked and held to the buffer body via the insert and the clamping component.

[0005] Existing technical documents Patent documents Patent document 1: Japanese Patent Application Publication No. 2016-88365. Summary of the Invention

[0006] The problem that the invention aims to solve In the fastening member of Patent Document 1, which consists of an insert and a clamping member, it is difficult to remove the fixed insert from the clamping member when the insert mounted on the skin component is locked and fixed to the clamping member fixed to the buffer body. Therefore, for example, when repairing a vehicle seat, the operation of peeling the skin component off the buffer body can easily become cumbersome.

[0007] In Patent Document 1, the outer skin component is formed by sewing multiple skin pieces together with sewing thread, and a seam portion consisting of sewing thread is formed at the sewn portion of the skin pieces. Furthermore, the insert in Patent Document 1 is attached to the outer skin component by sewing the insert's strap together with the skin portion of the outer skin component through the aforementioned seam portion. However, depending on the shape or design of a vehicle seat, if the seam portion of the outer skin component has a complex shape, it may be difficult to sew the two skin portions and the insert together.

[0008] Furthermore, in Patent Document 1, multiple skin parts and inserts are sewn together in an overlapping manner, thereby being stitched together as one piece by a seam. Therefore, it is difficult to modify only a portion of the skin part of the skin component in order to repair vehicle seats or change the design.

[0009] The present invention was made in view of the above-mentioned problems, and its object is to provide a fastening component and fastening method that can fix the skin component to the buffer body and can easily peel the skin component off the buffer body.

[0010] means for solving problems To achieve the above objectives, the fastening member of the present invention is a fastening member for locking and holding a skin member having a first skin portion and a second skin portion in a buffer body.

[0040] Hereinafter, suitable embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0041] (Example 1) Figure 1 This is a schematic cross-sectional view showing the fastening component of this embodiment. Figure 2 , Figure 3 ,as well as Figure 4 These are, respectively, a perspective view, a plan view, and a front view of the clamping component of the fastening component in Embodiment 1.

[0042] In the following description of the fastening components, the front-to-back direction refers to the direction along the length of the zipper strap on the zipper beam, the foot of the clamping component, and the length of the storage space. The length dimension refers to the size of this part in the front-to-back direction (length direction).

[0043] The vertical direction refers to the direction extending from the base along the foot of the clamping component, and the direction along the height of the foot. Specifically, in the height direction of the foot, the direction away from the base is defined as upward, and the direction closer to the base is defined as downward. The height dimension refers to the dimension of this part in the vertical direction (height direction).

[0044] The left-right direction refers to the direction along the width of the base and feet of the clamping component. Furthermore, in the left-right direction, the orientation of the feet towards each other is defined as the inner side in the left-right direction, and the orientation of the feet away from each other is defined as the outer side in the left-right direction. The width dimension refers to the size of this part in the left-right direction (width direction).

[0045] like Figure 1 As shown, when the skin component 10 is covered and installed on the surface of the buffer body 6, the fastening component 1 of this embodiment is used to lock and hold a portion of the skin component 10 to the buffer body 6. This fastening component 1 is used, for example, in a seat for a vehicle such as an automobile.

[0046] The fastening component 1 of this embodiment has: a first zipper beam 21 and a second zipper beam 22, which are installed on the skin component 10; and a plurality of clamping components 30, which are fixed to the buffer body 6 and engage the first zipper beam 21 and the second zipper beam 22.

[0047] In this first embodiment, the outer skin component 10 is a sheet-like component formed from fabric and possesses softness. It should be noted that the outer skin component 10 can also be formed from components other than fabrics, such as synthetic leather. The outer skin component 10 of this first embodiment has at least a first outer skin portion (first outer skin sheet) 11 and a second outer skin portion (second outer skin sheet) 12, which are cut to the desired shape. The first outer skin portion 11 and the second outer skin portion 12 are formed from different fabrics that are separated from each other by cutting. It should be noted that, in this invention, the first outer skin portion 11 and the second outer skin portion 12 can also be formed from different parts of a continuous fabric.

[0048] By engaging the zipper teeth 24 of the first zipper beam 21 installed on the first skin portion 11 with the zipper teeth 24 of the second zipper beam 22 installed on the second skin portion 12, the first skin portion 11 and the second skin portion 12 are connected to each other, thereby forming the skin component 10.

[0049] In this case, the first skin portion 11 and the second skin portion 12 are connected via the first zipper beam 21 and the second zipper beam 22, thereby forming the skin connection portion 15 of the skin component 10. The skin connection portion 15 is continuously formed to the desired length on the back side of the skin component 10.

[0050] The cushioning body 6 covering the outer skin component 10 is foamed and molded using a foaming resin such as polyurethane foam to form a shape corresponding to the shape of the manufactured seat. A receiving groove 7 is provided on the outer surface of the cushioning body 6 in a manner corresponding to the location and length of the outer skin connecting portion 15 of the outer skin component 10. This receiving groove 7 is used to pull in and receive the outer skin connecting portion 15 of the outer skin component 10.

[0051] Figures 2-4 The clamping component 30 shown is fixed within the receiving groove 7 of the buffer body 6. In this embodiment, multiple clamping components 30 are fixed to the bottom of the receiving groove 7 of the buffer body 6 at intervals along the length of the receiving groove 7.

[0052] During the foaming molding of the buffer body 6, multiple clamping components 30 are fixed to the buffer body 6 by insert molding. That is, foaming molding is performed with multiple clamping components 30 installed in predetermined positions within the mold for molding the buffer body 6, thereby fixing the multiple clamping components 30 to the foamed buffer body 6 within the mold and achieving integration with it. It should be noted that, in this invention, the method and means of fixing the clamping components 30 to the buffer body 6 are not particularly limited.

[0053] In this embodiment, the first zipper beam 21 and the second zipper beam 22 respectively include: a zipper tape 23, which has a long and thin strip shape; a plurality of zipper teeth 24, which are coil-shaped and installed on the zipper tape 23; and a core cord (not shown), which is inserted into the interior of the zipper teeth 24.

[0054] Since the plurality of zipper teeth 24 of the first zipper beam 21 and the second zipper beam 22 in this embodiment are respectively installed on the lower surface (with the back side) of the zipper belt 23, it is formed as a so-called back-side-use type zipper beam.

[0055] The zipper tape 23 is formed of a fabric or braided structure of multiple synthetic fibers, possessing flexibility that allows it to be easily bent. For example, in a cross-sectional view orthogonal to the length direction of the tape, the zipper tape 23 has: a tape body portion sewn to a first skin portion 11 or a second skin portion 12; and a zipper tooth mounting portion (tape side edge portion) extending from a side edge of one side of the tape body portion. The zipper tape 23 has an upper surface (tape surface) that contacts the first skin portion 11 or the second skin portion 12, and a lower surface (tape back) that contacts the zipper teeth 24.

[0056] Multiple zipper teeth 24 are formed by winding monofilaments made of thermoplastic resin such as polyamide or polyester into coils, thus having a continuous, uninterrupted shape. With the core cord (not shown) inserted into the zipper teeth 24, the multiple zipper teeth 24 are sewn to the zipper tape 23 by sewing thread (not shown). Thus, a row of teeth formed by the multiple zipper teeth 24 is formed along the length of the tape at the side edge of the zipper tape 23.

[0057] Each zipper tooth 24 has: an engagement head 24a that engages with the zipper tooth 24 to which it is engaged; a pair of upper and lower tooth feet 24b and 24c that extend from the upper and lower ends of the engagement head 24a; and a connecting portion 24d that connects the upper tooth foot 24b (or the lower tooth foot 24c) of the zipper tooth 24 to the lower tooth foot 24c (or the upper tooth foot 24b) of the zipper tooth 24 adjacent in the front-back direction.

[0058] In this embodiment, the first zipper beam 21 and the second zipper beam 22 are respectively sewn to the side edge 11a of the first skin portion 11 and the side edge 12a of the second skin portion 12 of the skin component 10. In this case, by folding and overlapping a portion of the first skin portion 11, the fabric of the side edge 11a of the first skin portion 11 is formed into a double-layered overlapping form. Similar to the first skin portion 11, the fabric of the side edge 12a of the second skin portion 12 is also formed into a double-layered overlapping form.

[0059] The zipper tape 23 of the first zipper beam 21 is attached to the side edge 11a of the first outer skin portion 11 by sewing, for example, using a sewing machine, while overlapping the side edge 11a of the first outer skin portion 11. Similarly, the zipper tape 23 of the second zipper beam 22 is also attached to the side edge 12a of the second outer skin portion 12. The zipper tape 23 can be sewn to the overlapping portion of the fabric, or sewn to one side of the overlapping portion of the fabric.

[0060] In this first embodiment, the plurality of zipper teeth 24 of the first zipper beam 21 and the plurality of zipper teeth 24 of the second zipper beam 22 are connected, for example, by using a zipper pull 80 (see reference). Figure 6 The zipper pull 80 is detachably mounted on the chain teeth of the first zipper beam 21 and the second zipper beam 22. Thus, the side edge 11a of the first skin portion 11 and the side edge 12a of the second skin portion 12 are connected to each other via the first zipper beam 21 and the second zipper beam 22.

[0061] It should be noted that, for convenience, Figure 6 The zipper pull 80 shown is configured such that a portion of the first zipper beam 21 (i.e., a portion of the zipper tape 23 and the zipper teeth 24), a portion of the second zipper beam 22, a portion of the first skin portion 11, and a portion of the second skin portion 12 are inserted into the interior of the zipper pull body. However, in this invention, the zipper pull can be configured as shown in Embodiment 1, or it can be configured such that a portion of the first zipper beam 21 and a portion of the second zipper beam 22 are inserted into the interior of the zipper pull body, but the first skin portion 11 and the second skin portion 12 are not inserted.

[0062] In this embodiment, each clamping component 30 is formed of synthetic resin to be elastically deformable. For example... Figures 2-4 As shown, the clamping member 30 includes: a flat base 31; a pair of left and right legs 32 extending upward from the upper surface of the base 31; a pair of left and right engaging protrusions 33 protruding from the inner side of each left and right leg 32 toward the other leg 32; and a storage space 35 disposed between the left and right legs 32.

[0063] From a plan view or a bottom view, the base 31 of the clamping member 30 has a thin plate-like shape that appears quadrilateral or substantially quadrilateral. In this embodiment, the base 31 is formed such that its length (dimension in the front-to-back direction) is smaller than its width (dimension in the left-to-right direction). The upper and lower surfaces of the base 31 are formed as flat surfaces orthogonal to the vertical direction. The base 31 has appropriate strength for supporting the left and right feet 32.

[0064] The base 31 has: a central base portion 31a disposed on the inner side in the left-right direction from the position of the left and right feet 32; and left and right base side edges 31b disposed on the outer side in the left-right direction, further from the position of the left and right feet 32. When the clamping member 30 is fixed to the buffer body 6, the left and right base side edges 31b of the base 31 are embedded within the buffer body 6. This improves the fixing strength of the clamping member 30 relative to the buffer body 6. It should be noted that in this invention, the shape and size of the base 31 are not particularly limited as long as it is formed to support the left and right feet 32 ​​in a predetermined position.

[0065] The left and right feet 32 ​​are erected on the upper surface of the base 31 along the vertical direction. The left and right feet 32 ​​are arranged parallel to each other along the front-back direction at a distance spaced inward from the left and right side edges of the base 31 in the left-right direction. The left and right feet 32 ​​are arranged separately from each other in the left-right direction to form a storage space 35 between the left and right feet 32 ​​for storing the engaging left and right zipper teeth 24.

[0066] For example, in this first embodiment, when the entire width dimension (dimension in the width direction) from the left edge to the right edge of the base 31 is set to 100%, the left foot 32 is positioned within a range of 15% to 35% of the width dimension of the base 31, starting from the left end edge of the base 31. Furthermore, the right foot 32 is positioned within a range of 65% to 85% of the width dimension of the base 31, starting from the left end edge of the base 31.

[0067] The left and right feet 32 ​​have a face-symmetrical shape with reference to the center plane of the center in the left-right direction of the clamping member 30. For example, when a cross section orthogonal to the front-back direction is observed, each of the left and right feet 32 ​​has: a base end 32a, which is connected to the base 31; a middle part 32b, which extends upward from the base end 32a, and the width dimension of the foot 32 gradually increases as it moves away from the base 31; and a front end (upper end) 32c, which extends further upward from the middle part 32b.

[0068] The base end 32a of the foot 32 has a certain width dimension and extends upward from the base 31, and is formed as the thinnest part of the foot 32.

[0069] The width of the foot 32 gradually increases from the middle portion 32b towards the front portion 32c of the foot 32. Specifically, in this embodiment, the middle portion 32b has the following shape: the inner surface of the middle portion 32b forms a plane with the inner surface of the base portion 32a, and the outer surface of the middle portion 32b is inclined relative to the vertical direction. For example, compared to the case where the outer surfaces of the base portion, middle portion, and front portion of the foot form a plane, by inclining the outer surface of the middle portion 32b in this way, the area of ​​the outer surface of the foot 32 can be increased. Therefore, the fixation strength when the outer surface of the foot 32 is fixed to the buffer body 6 can be improved.

[0070] The front end 32c of the foot 32 includes the portion of the foot 32 with the largest width dimension.

[0071] Each of the left and right feet 32 ​​has a base end portion 32a, a middle portion 32b, and a front end portion 32c as described above. For example, when the left and right feet 32 ​​are elastically deformed in the left and right direction, the thin base end portion 32a of the foot 32 can be elastically deformed mainly, and the middle portion 32b and the front end portion 32c of the foot 32 can be formed into rigid portions that are not elastically deformable or difficult to elastically deform.

[0072] Therefore, for example, when the first zipper beam 21 and the second zipper beam 22 are engaged with the clamping member 30, the interlocking left and right zipper teeth 24 of the first zipper beam 21 and the second zipper beam 22 are inserted between the left and right legs 32 of the clamping member 30 and moved to the storage space 35. At this time, in this embodiment, the left and right legs 32 can be elastically deformed mainly at the base end 32a (preferably only at the base end 32a) without elastic deformation in the entire height direction. As a result, the gap between the left and right legs 32 can be widened, so that the zipper teeth 24 can pass over the left and right engaging protrusions 33.

[0073] For example, compared to the case where the left and right feet 32 ​​elastically deform along the entire height direction of the foot 32, by generating elastic deformation of the foot 32 mainly at the base end 32a, the deformation action of the foot 32 can be stabilized (in other words, the foot 32 can be elastically deformed with a substantially fixed action). Furthermore, the left and right feet 32 ​​can be easily elastically deformed outward with a small force.

[0074] For example, in this first embodiment, the base end portion 32a of the foot 32 has a height dimension (vertical dimension) that is more than 20% and less than 50% of the total height dimension of the foot 32. By making the height dimension of the base end portion 32a more than 20% of the total height dimension of the foot 32, the elastic deformation of the foot 32 can be stably generated mainly at the base end portion 32a. Furthermore, by making the height dimension of the base end portion 32a less than 50% of the total height dimension of the foot 32, the deformation movement of the foot 32 can be easily stabilized.

[0075] The inner surface of the front end portion 32c of the foot portion 32 has: a continuous surface that forms the same plane as the inner surfaces of the base end portion 32a and the middle portion 32b; and a guide inclined surface 32d that is inclined relative to the vertical direction. The guide inclined surface 32d of the front end portion 32c is positioned higher than the continuous surface and is inclined outward in the width direction such that the width dimension of the front end portion 32c gradually decreases upward. By forming such a guide inclined surface 32d on the inner surface of the front end portion 32c, the zipper tooth 24 can be guided between the left and right foot portions 32 when it is inserted between them. Therefore, the insertion operation of the zipper tooth 24 can be performed easily.

[0076] Each of the left and right engaging protrusions 33 protrudes inward in the left-right direction from the inner side of the middle portion 32b and the front end portion 32c (i.e., the rigid portion) of the foot portion 32. The engaging protrusions 33 of this embodiment are shown, for example, in the front view of the clamping member 30 (…). Figure 4 In the middle, it is formed as a roughly triangular protrusion from the inner side of the foot 32.

[0077] like Figure 4 As shown, each of the left and right engaging protrusions 33 has: a downwardly inclined surface 33a that slopes downward from the front end 32c of the foot 32 toward the inner side in the left-right direction; a lower end surface 33b that extends from the middle part 32b of the foot 32 toward the inner side in the left-right direction; and a front end surface that is formed parallel to the up-down direction from the downwardly inclined surface 33a of the engaging protrusion 33 to the lower end surface 33b.

[0078] The engaging protrusion 33 has the aforementioned downwardly inclined surface 33a, which guides the zipper teeth 24 of the first zipper beam 21 and the second zipper beam 22 to the center portion in the width direction between the left and right foot portions 32. Furthermore, when the zipper teeth 24 are pressed toward the storage space portion 35, the left and right foot portions 32 can be pressed outward in the width direction by the zipper teeth 24, thereby enabling the left and right foot portions 32 to elastically deform.

[0079] The lower end face 33b of the engaging protrusion 33 is formed as a flat surface orthogonal to the vertical direction. By providing such a lower end face 33b in the engaging protrusion 33, when the zipper teeth 24 move and are housed in the housing space 35 of the clamping member 30, the left and right zipper teeth 24 can be stably engaged with the left and right engaging protrusions 33 (see reference). Figure 1 ).

[0080] For example, in the planar view of the clamping component 30 ( Figure 3 In this embodiment, the left and right engaging protrusions 33 protrude in a near-triangular shape from the entire front-rear direction of the foot portion 32 toward the inner side in the left-right direction. In other words, the left and right engaging protrusions 33 are configured to cover 100% of the front-rear direction of the foot portion 32, and the entire engaging protrusions 33 overlap each other in their relative formation range in the front-rear direction. In this way, the left and right engaging protrusions 33 are formed to be longer in the front-rear direction, so that the left and right zipper teeth 24 housed in the storage space 35 of the clamping member 30 can be stably engaged with the left and right engaging protrusions 33.

[0081] In the above planar perspective ( Figure 3 In this configuration, the left and right engaging protrusions 33 have asymmetrical shapes relative to the center line of the clamping member 30 (particularly between the left and right feet 32) in the width direction. In this case, the center line is parallel to the front-back direction. Furthermore, the left and right engaging protrusions 33 have point-symmetric shapes relative to each other.

[0082] In the above planar perspective ( Figure 3 Each engaging protrusion 33 has: a first inclined surface 34a, which is disposed on one side (front or rear) in the front-rear direction of the engaging protrusion 33 and is inclined relative to the front-rear direction; a second inclined surface 34b, which is disposed on the other side (rear or front) in the front-rear direction of the engaging protrusion 33 and is inclined relative to the front-rear direction; and a top surface 34c, which is disposed between the first inclined surface 34a and the second inclined surface 34b.

[0083] It should be noted that, in this first embodiment, the first inclined surface 34a and the second inclined surface 34b of the engaging protrusion 33 correspond to the inclined portion of the engaging protrusion described in the "requested scope". Furthermore, the first inclined surface 34a and the second inclined surface 34b correspond to the first inclined portion and the second inclined portion of the engaging protrusion described in the "requested scope", respectively.

[0084] The first inclined surface 34a, the second inclined surface 34b, and the top surface 34c of the engaging protrusion 33 are each formed as flat surfaces (see reference). Figure 2It should be noted that, in this invention, the first inclined surface 34a, the second inclined surface 34b, and the top surface 34c of the engaging protrusion 33 may also be formed as curved surfaces or other surfaces other than flat surfaces.

[0085] In the above planar perspective ( Figure 3 In this configuration, the second inclined surface 34b of the engaging protrusion 33 is inclined at a greater angle relative to the vertical direction than the first inclined surface 34a. In other words, the first inclined surface 34a is configured to be inclined more gently than the second inclined surface 34b. Furthermore, the first inclined surface 34a is formed to be longer than the second inclined surface 34b. It should be noted that the angles of inclination of the first inclined surface 34a and the second inclined surface 34b relative to the vertical direction refer to the angles on the inner corner side of the engaging protrusion 33.

[0086] Here, the tilt angle of the engaging protrusion 33 will be explained in detail. From the aforementioned planar perspective ( Figure 3 In this embodiment, the first inclined surface 34a of the engaging protrusion 33 has an inclination angle of 5° to 30° relative to the vertical direction, preferably 10° to 20°. The second inclined surface 34b has an inclination angle of 15° to 50° relative to the vertical direction, preferably 20° to 40°. The top surface 34c of the engaging protrusion 33 is inclined at a smaller angle to the vertical direction than the first inclined surface 34a. For example, in this embodiment, the top surface 34c has an inclination angle greater than 0° and less than 10° relative to the vertical direction. It should be noted that the top surface 34c can also be configured to be parallel to the vertical direction.

[0087] In the above planar perspective ( Figure 3 The first inclined surface 34a of the engaging protrusion 33 is continuously disposed within a range of 50% to 80% relative to the formation range of the entire foot 32 in the front-rear direction, or relative to the entire formation range from the front edge to the rear edge of the clamping member 30.

[0088] The left and right top surfaces 34c are positioned at different locations in the front-back direction. For example, in this embodiment, the left and right top surfaces 34c are positioned opposite to the first inclined surface 34a of the opposite engaging protrusion 33. The left and right second inclined surfaces 34b are positioned opposite to the first inclined surface 34a of the opposite engaging protrusion 33. Furthermore, each second inclined surface 34b is continuously positioned within a range of 10% to less than 50% of the total front-back direction of the foot 32.

[0089] In the above planar perspective ( Figure 3Under these conditions, the maximum width of the left and right engaging protrusions 33 is set to be more than 10% and less than 45% of the interval between the left and right foot portions 32. The minimum distance between the left and right engaging protrusions 33 is set to be less than the tooth width L1 of the engaged left and right zipper teeth 24.

[0090] Here, for example, such as Figure 6 As shown, the zipper tooth width L1 is the maximum value of the width of the two engaged zipper teeth 24 after the zipper teeth 24 of the first zipper beam 21 and the zipper teeth 24 of the second zipper beam 22 are engaged. In other words, the zipper tooth width L1 is the dimension in the left-right direction from the leftmost part of the left zipper tooth 24 to the rightmost part of the right zipper tooth 24 when the left and right zipper teeth 24 are engaged.

[0091] Furthermore, in this first embodiment, the aforementioned planar perspective ( Figure 3 The shortest distance between the left and right engaging protrusions 33 under the above-mentioned planar perspective ( ) refers to the distance when the first inclined surface 34a of the left engaging protrusion 33 and the first inclined surface 34a of the right engaging protrusion 33 are connected in a direction orthogonal to the first inclined surface 34a. Further, the left and right engaging protrusions 33 are formed such that the interval between the left and right engaging protrusions 33 is within the above-mentioned planar perspective ( ) Figure 3 The maximum value is at the front and rear ends of the clamping component 30.

[0092] The left and right engaging protrusions 3 are formed as described above, so that when the left and right zipper teeth 24 are pressed downward in order to move them to the storage space 35 of the clamping member 30, the left and right zipper teeth 24 can be easily moved to the storage space 35 through the gap between the left and right engaging protrusions 33.

[0093] In particular, at this time, by tilting the first zipper beam 21 and the second zipper beam 22 along the first inclined surface 34a relative to the vertical direction and pressing them from the front or rear end of the clamping member 30 toward the storage space 35, the left and right zipper teeth 24 can easily pass over the left and right engaging protrusions 33 of the clamping member 30. Therefore, the zipper teeth 24 can be smoothly moved to the storage space 35 of the clamping member 30.

[0094] Furthermore, when the left and right zipper teeth 24 move and are stored in the storage space 35 of the clamping member 30, the left and right zipper teeth 24 can be stably engaged with the left and right engagement protrusions 33.

[0095] Furthermore, when the left and right zipper teeth 24 housed in the storage space 35 of the clamping member 30 are removed from the clamping member 30, the first zipper beam 21 and the second zipper beam 22 are tilted relative to the vertical direction along the first inclined surface 34a, and the first zipper beam 21 and the second zipper beam 22 are pulled upward from the front or rear end of the clamping member 30. This allows the left and right zipper teeth 24 to be easily pulled out from the storage space 35 of the clamping member 30, releasing the engagement between the first zipper beam 21 and the second zipper beam 22 and the clamping member 30.

[0096] The storage space 35 of the clamping member 30 is formed in the left-right direction within the range from the foot 32 on one side (left) to the foot 32 on the other side (right), and in the up-down direction within the range from the upper surface of the base 31 to the lower end face 33b of the left and right engaging protrusions 33.

[0097] The storage space 35 in this embodiment is formed to the following size. Here, the maximum value of the dimension in the width direction of the storage space 35 is defined as the space width dimension D1 (refer to...). Figure 6 ).

[0098] For example, the width D1 of the storage space 35 is set to be the same as, smaller than, or larger than the tooth width L1 of the engaged left and right zipper teeth 24. Therefore, when the engaged left and right zipper teeth 24 move into the storage space 35, they can always be in contact with or pressed against the inner surfaces of the left and right foot portions 32, or remain in contact. Thus, the left and right foot portions 32, together with the left and right engaging protrusions 33, can press the left and right zipper teeth 24 and stably hold them within the storage space 35.

[0099] Here, holding the left and right zipper teeth 24 within the storage space 35 so that they can contact the inner surfaces of the left and right foot parts 32 includes, for example, holding one of the left and right zipper teeth 24 in contact with the inner surface of the foot part 32 and slightly loosely holding the left and right zipper teeth 24 within the storage space 35 in the width direction, and holding the left and right zipper teeth 24 within the storage space 35 while slightly separating them from the inner surfaces of the left and right foot parts 32. In the above cases, by moving the left and right zipper teeth 24 within the storage space 35 or bending the left and right foot parts 32, one or both of the left and right zipper teeth 24 can contact the inner surfaces of the left and right foot parts 32.

[0100] The maximum height of the storage space section 35 is not particularly limited, but it is set to be more than 100% and less than 250% of the maximum height of the engaged left and right zipper teeth 24.

[0101] In the clamping member 30 of this embodiment, a gap is formed between the left and right engaging protrusions 33. This gap is used to insert the engaged left and right zipper teeth 24 toward the receiving space 35. Here, from the front view of the clamping member 30, the minimum value of the dimension of the gap between the left and right engaging protrusions 33 in the width direction is defined as the minimum width gap S1 (refer to...). Figure 6 ).

[0102] In this case, the minimum width interval S1 between the left and right engaging protrusions 33 is set to be smaller than the tooth width L1 of the left and right zipper teeth 24. Therefore, when the engaging left and right zipper teeth 24 pass between the left and right engaging protrusions 33 and move into the storage space 35, as... Figure 1 As shown, the left and right engaging protrusions 33 interfere with the left and right zipper teeth 24, which can stably engage the left and right zipper teeth 24.

[0103] Specifically, in this first embodiment, from the planar perspective of the clamping component 30 ( Figure 3 As shown above, the shortest distance between the first inclined surface 34a of the left engaging protrusion 33 and the first inclined surface 34a of the right engaging protrusion 33 is set to be smaller than the tooth width L1 of the left and right zipper teeth 24.

[0104] Therefore, the left and right zipper teeth 24, which have moved to the storage space 35, can more stably engage with the left and right engagement protrusions 33. In this first embodiment, the shortest distance between the left first inclined surface 34a and the right first inclined surface 34a from the planar view of the clamping member 30 is set to be greater than the distance from the planar view of the clamping member 30. Figure 6 The space width dimension D1 between the left and right engaging protrusions 33 is small.

[0105] Next, we will describe a method for connecting the first skin portion 11 and the second skin portion 12 using the fastening component 1 of this embodiment, and further for holding the first skin portion 11 and the second skin portion 12 in the buffer body 6. The fastening component 1 includes: a first zipper beam 21, which is installed on the first skin portion 11; a second zipper beam 22, which is installed on the second skin portion 12; and a plurality of clamping components 30, which are fixed to the buffer body 6.

[0106] In this first embodiment, as Figure 5As shown, the first zipper beam 21 and the second zipper beam 22 are pre-sewn to the side edge 11a of the first skin portion 11 and the side edge 12a of the second skin portion 12 by sewing with a sewing machine. Multiple clamping components 30 are fixed to the buffer body 6 by insert molding during the foaming process of the buffer body 6. That is, during the foaming process of the buffer body 6, the clamping components 30 are fixed within the receiving groove 7 of the molded buffer body 6 by being installed at a predetermined position inside the foaming mold.

[0107] As described above, after preparing the first zipper beam 21, the second zipper beam 22, and the clamping component 30, the zipper pull 80 is first installed onto the tooth rows of the first zipper beam 21 and the second zipper beam 22. In this embodiment, the zipper pull 80 is detachably installed from one end of the tooth row along its length onto a pair of left and right tooth rows. It should be noted that the shape and structure of the zipper pull 80 are not particularly limited in this invention, and conventionally known zipper pulls can be used to engage or disengage the coiled zipper teeth 24.

[0108] After the zipper pull 80 is installed on the zipper teeth of the first zipper beam 21 and the second zipper beam 22, the zipper pull 80 is slid along the zipper teeth. As a result, the zipper teeth 24 of the first zipper beam 21 and the zipper teeth 24 of the second zipper beam 22 can be sequentially engaged along the entire length of the zipper teeth.

[0109] In this way, by engaging the left and right zipper teeth 24, as... Figure 6 As shown, the first cover portion 11 and the second cover portion 12 are connected via the first zipper longitudinal beam 21 and the second zipper longitudinal beam 22 to form the cover component 10. Furthermore, after the zipper teeth 24 are engaged, the zipper pull 80 is detached from the tooth row. It should be noted that in this invention, the zipper pull 80 may not be detached from the tooth row. Alternatively, the zipper pull 80 may be mounted to the first zipper longitudinal beam 21 and the second zipper longitudinal beam 22 in a manner that prevents it from being detached from the tooth row.

[0110] After forming the skin component 10, the obtained skin component 10 is covered on the buffer body 6, and the zipper teeth of the first zipper beam 21 and the second zipper beam 22 installed on the skin component 10 are inserted into the receiving groove 7 of the buffer body 6 along the receiving groove 7.

[0111] At this time, a portion of the skin component 10 is pulled into the receiving groove 7, and the first skin portion 11 and the second skin portion 12 overlap. Consequently, on the back side of the skin component 10, a skin connecting portion 15, corresponding to the receiving groove 7, is continuously formed and housed within the receiving groove 7. At the front end (lower end) of this skin connecting portion 15, the engaged left and right chain teeth are arranged along the skin connecting portion 15.

[0112] Furthermore, the zipper teeth of the first zipper beam 21 and the second zipper beam 22 are inserted between the left and right pairs of legs 32 of the clamping member 30, which is fixed in the receiving groove 7, with the left and right zipper teeth 24 engaged with each other. At this time, as described above, since the guide inclined surface 32d is provided at the front end 32c of the left and right legs 32, the left and right zipper teeth 24 can be easily inserted between the left and right legs 32.

[0113] Next, the left and right zipper teeth (zipper teeth 24) inserted between the pair of feet 32 ​​are pressed downwards, moving them into the storage space 35 of the clamping member 30. As a result, the left and right zipper teeth 24 come into contact with the left and right engaging protrusions 33 of the clamping member 30 (especially the downward inclined surface 33a of the engaging protrusions 33).

[0114] Furthermore, the zipper teeth 24, which are in contact with the downwardly inclined surface 33a of the engaging protrusions 33, are pressed and moved downwards, thereby applying stress to the left and right feet 32 ​​via the downwardly inclined surface 33a. As a result, the left and right feet 32 ​​elastically deform in a manner that expands outwards in the left and right direction. At this time, as described above, since the base ends 32a of the feet 32 ​​elastically deform, the deformation action of the feet 32 ​​is stable, thereby smoothly widening the gap between the left and right engaging protrusions 33.

[0115] Subsequently, the left and right zipper teeth 24 are pressed downwards, widening the gap between the left and right engaging protrusions 33 to the same or approximately the same size as the engaged left and right zipper teeth 24. This allows the left and right zipper teeth 24 to pass over the left and right engaging protrusions 33 and move into the storage space 35 of the clamping member 30. Further, the movement of the left and right zipper teeth 24 into the storage space 35 releases the interference between the zipper teeth 24 and the engaging protrusions 33, and the left and right feet 32 ​​elastically return to their original position.

[0116] Thus, the zipper teeth of the first zipper beam 21 and the second zipper beam 22 are stored in the storage space 35 while the left and right zipper teeth 24 are engaged. Furthermore, the left and right engaging protrusions 33 are inserted between the zipper teeth 24 and the zipper tape 23 of the first zipper beam 21 and the second zipper beam 22, engaging with the portion of the first zipper beam 21 and the second zipper beam 22 including the zipper teeth 24 (specifically, between the zipper teeth 24 and the zipper tape 23).

[0117] Furthermore, in this first embodiment, as described above, the left and right engaging protrusions 33 of the clamping member 30 have asymmetrical shapes relative to each other, based on the center line in the width direction of the clamping member 30. Furthermore, the spacing between the left and right engaging protrusions 33 of the clamping member 30 is formed such that, from the aforementioned planar perspective (… Figure 3The zipper teeth are largest at the front and rear ends of the clamping member 30. Therefore, when the engaged left and right zipper teeth 24 are pressed downwards and moved to the storage space 35 of the clamping member 30 as described above, it is preferable to press the left and right zipper teeth 24 (tooth rows) from the front (or rear) end of the clamping member 30 towards the storage space 35. This makes it easier to move the left and right zipper teeth 24 to the storage space 35 of the clamping member 30.

[0118] Furthermore, in this first embodiment, a gently sloping first inclined surface 34a is formed on the left and right engaging protrusions 33 of the clamping member 30. This first inclined surface 34a is longer than the second inclined surface 34b in the front-back direction. Therefore, when the engaged left and right zipper teeth 24 are pressed downward as described above, for example, preferably while partially twisting a portion of the first zipper beam 21 and the second zipper beam 22, the left and right zipper teeth 24 are pressed into the receiving space 35 of the clamping member 30 so that the orientation of the tooth row is parallel or substantially parallel to the first inclined surface 34a of the engaging protrusions 33. As a result, the left and right zipper teeth 24 can be moved into the receiving space 35 of the clamping member 30 with less force.

[0119] It should be noted that even when the zipper teeth 24 are inserted into the clamping member 30, a portion of the first zipper beam 21 and the second zipper beam 22 are partially twisted as described above. After the zipper teeth 24 are inserted, the first zipper beam 21 and the second zipper beam 22 are pulled by the tension from the cover member 10, thereby allowing the first zipper beam 21 and the second zipper beam 22 to extend. As a result, the partial twisting of the first zipper beam 21 and the second zipper beam 22 can be automatically corrected.

[0120] Then, in this embodiment, by inserting the chain teeth of the first zipper beam 21 and the second zipper beam 22 into the storage groove 7 and pressing them against the multiple clamping members 30 fixed in the storage groove 7 of the buffer body 6, the chain teeth can be stored in the storage space 35 of each clamping member 30, and the engaged left and right zipper teeth 24 can engage the left and right engaging protrusions 33 of each clamping member 30.

[0121] At this time, the left and right zipper teeth 24 contact the engaging protrusion 33 of the clamping member 30 through the outer part (edge ​​part) of the upper foot 24b of the zipper teeth 24 and at least a part of the connecting part 24d, thereby engaging and holding in the engaging protrusion 33.

[0122] Furthermore, in this first embodiment, due to the aforementioned relationship between the spatial width D1 of the storage space 35 and the tooth width L1 of the zipper teeth 24, when the left and right zipper teeth 24 are stored within the storage space 35, they can be held in contact with the inner surfaces of the left and right feet 32, or always in contact with or pressed against the inner surfaces of the left and right feet 32. Thus, the left and right feet 32 ​​of the clamping member 30, together with the left and right engaging protrusions 33, can press the left and right zipper teeth 24, stably holding them within the storage space 35. Moreover, since the left and right zipper teeth 24 are pressed from the outside in the left and right direction by the left and right feet 32, it is difficult for the left and right zipper teeth 24 to separate within the storage space 35.

[0123] As described above, in this first embodiment, after the first zipper beam 21 and the second zipper beam 22 installed on the first skin portion 11 and the second skin portion 12 are engaged to form the skin component 10, the engaging left and right zipper teeth 24 of the first zipper beam 21 and the second zipper beam 22 can be engaged with the clamping members 30 fixed to the buffer body 6. Therefore, the skin component 10 (first skin portion 11 and second skin portion 12) covering the buffer body 6 can be locked and held in place by the clamping members 30 fixed to the buffer body 6, thus easily and stably fixing the skin component 10 to the buffer body 6.

[0124] Next, the method for removing the skin component 10 fixed to the buffer body 6 in this first embodiment will be described.

[0125] When the outer skin component 10 is removed from the buffer body 6, the meshing left and right zipper teeth 24 of the first zipper longitudinal beam 21 and the second zipper longitudinal beam 22 are first separated.

[0126] At this time, the first zipper beam 21 and the second zipper beam 22 are not equipped with the zipper pull 80. In addition, the interlocking left and right zipper teeth 24 in one end and the other end of the first zipper beam 21 and the second zipper beam 22 along the length direction are exposed and not protected by fastening components or the like.

[0127] Therefore, for example, by applying a lateral pulling force to the engaging left and right zipper teeth 24 at one end or the other end in the length direction of the zipper teeth row, which pulls the left and right zipper teeth 24 outward in the width direction, the left and right zipper teeth 24 can be easily separated from one end or the other end in the length direction.

[0128] Furthermore, in this first embodiment, while the left and right zipper teeth 24 are sequentially separated, one of the first zipper beam 21 and the second zipper beam 22 is pulled to disengage the zipper teeth 24 from the storage space 35 of the clamping member 30. Thus, the zipper teeth 24 of only one of the first zipper beam 21 and the second zipper beam 22 can be easily pulled out and removed from the storage space 35 of each clamping member 30 via the gap between the left and right engaging protrusions 33.

[0129] Furthermore, in this case, when the separated zipper teeth 24 are pulled out from the storage space 35 of the clamping member 30, it is preferable to partially twist a portion of the pulled first zipper beam 21 or second zipper beam 22 in a manner parallel or substantially parallel to the first inclined surface 34a of the engaging protrusion 33. This allows one of the left and right zipper teeth 24 to be pulled out from the storage space 35 of the clamping member 30 with relatively little force.

[0130] Furthermore, as described above, while separating the left and right zipper teeth 24, one of the first zipper longitudinal beam 21 and the second zipper longitudinal beam 22 is removed from all the clamping parts 30 fixed to the buffer body 6, thereby making it easy to peel off the first skin portion 11 or the second skin portion 12 to which the first skin portion is sewn from the buffer body 6.

[0131] Then, pull the other of the first zipper beam 21 and the second zipper beam 22 to disengage the zipper teeth 24 from the storage space 35 of the clamping member 30. At this time, as described above, it is preferable to partially twist a portion of the first zipper beam 21 or the second zipper beam 22 in a manner parallel or substantially parallel to the first inclined surface 34a of the engaging protrusion 33. As a result, the zipper teeth 24 can be pulled out of the storage space 35 of the clamping member 30 with relatively little force. Consequently, the second skin portion 12 or the first skin portion 11, to which the other is sewn, can be easily removed from the buffer body 6 and peeled off.

[0132] As described above, by using the fastening member 1 of this embodiment 1 on the skin member 10 and the buffer body 6, the operation of covering and fastening the skin member 10 to the buffer body 6 and the operation of removing and peeling off the skin member 10 covering the buffer body 6 can be performed smoothly and stably.

[0133] Specifically, according to the fastening member 1 of this embodiment, the first skin portion 11 and the second skin portion 12 of the skin member 10 can be easily connected and separated via the first zipper beam 21 and the second zipper beam 22 of the fastening member 1. Therefore, when the skin member 10 is removed from the buffer body 6, the separated zipper teeth 24 can be easily pulled out from the storage space portion 35 of the clamping member 30 while separating the zipper teeth 24 of the first zipper beam 21 and the second zipper beam 22. Therefore, compared with the conventional fastening members (insert and clamping member) described in Patent Document 1, the fastening member 1 of this embodiment can easily peel the skin member 10 from the buffer body 6.

[0134] Furthermore, according to the fastening member 1 of this embodiment, the first zipper beam 21 and the second zipper beam 22 can be easily connected by sliding the zipper head 80. Therefore, for example, depending on the shape or design of the vehicle seat having the cover part 10 and the cushion 6, even if the cover connecting part 15 connecting the first cover part 11 and the second cover part 12 of the cover part 10 is formed in a complex shape, the sewing process of sewing the first zipper beam 21 to the first cover part 11 and the sewing process of sewing the second zipper beam 22 to the second cover part 12 can be performed as separate processes.

[0135] Therefore, by using the fastening component 1 of this embodiment, even if the vehicle seat has various shapes and designs, the first skin portion 11 and the second skin portion 12 of the skin component 10 can be easily connected via the first zipper longitudinal beam 21 and the second zipper longitudinal beam 22. Furthermore, the connected skin component 10 can be stably fastened to the buffer body 6 using the zipper teeth 24 of the first zipper longitudinal beam 21 and the second zipper longitudinal beam 22. As a result, the fastening component 1 of this embodiment expands the freedom of shape and design of the vehicle seat that can be manufactured.

[0136] Furthermore, in this first embodiment, the first zipper beam 21 and the second zipper beam 22 of the fastening component 1 can be easily connected and separated. Therefore, when repairing vehicle seats or changing the design of vehicle seats, it is easy to partially change only a portion of the cover component 10 (e.g., the first cover portion 11) to other fabrics.

[0137] (Example 2) Figure 7 , Figure 8 and Figure 9 These are, respectively, a perspective view, a plan view, and a front view schematically illustrating the clamping component of the fastening component in Embodiment 2.

[0138] The fastening component 2 of this embodiment has: a first zipper beam 21 and a second zipper beam 22, which are installed on the surface component 10 of the vehicle seat; and a plurality of clamping components 40, which are fixed to the buffer body 6 and engage the first zipper beam 21 and the second zipper beam 22.

[0139] It should be noted that in the fastening component 2 of this embodiment, the shape of the left and right engaging protrusions 43 provided on the clamping component 40 is different from that of the fastening component 1 of the aforementioned embodiment. However, except for the engaging protrusions 43, the other parts of the fastening component 2 are substantially the same as those of the fastening component 1 of the aforementioned embodiment. For example, in the fastening component 2 of this embodiment, the first zipper longitudinal beam 21 and the second zipper longitudinal beam 22 are formed in the same way as the first zipper longitudinal beam 21 and the second zipper longitudinal beam 22 of the aforementioned embodiment.

[0140] Therefore, in this second embodiment and the following third to fifth embodiments, the parts and structures that differ from the fastening component 1 in the first embodiment will be mainly described. Furthermore, in this second embodiment and the following third to fifth embodiments, for components and parts that are substantially the same as the fastening component 1 in the first embodiment, detailed descriptions are omitted by using the same symbols.

[0141] In this second embodiment, multiple clamping components 40 are fixed at intervals to each other at the bottom of the receiving groove 7 of the buffer body 6, along the length direction of the receiving groove 7. Figures 7-9 As shown, each clamping member 40 has: a flat base 41; a pair of left and right legs 42 extending upward from the upper surface of the base 41; a pair of left and right engaging protrusions 43 protruding from the inner side of each left and right leg 42 toward the other leg 42; and a storage space 45 disposed between the left and right legs 42. In this second embodiment, the base 41, the pair of legs 42, and the storage space 45 of the clamping member 40 are substantially the same as those of the clamping member 30 in the first embodiment. Therefore, the leg 42 has a base end 42a, a middle part 42b, and a front end 42c.

[0142] In the clamping member 40 of this embodiment 2, the left and right engaging protrusions 43 protrude inward in the left-right direction from the inner side of the middle part 42b and the front part 42c of the foot part 42. The engaging protrusions 43 of this embodiment 1 are viewed from the front of the clamping member 40. Figure 9 Below, it forms a roughly triangular protrusion from the inner side of the foot 42.

[0143] In this case, similar to the case in Embodiment 1 described above, the left and right engaging protrusions 43 are in the aforementioned frontal view ( Figure 9The following features: a downwardly inclined surface 43a that slopes downward from the front end 42c of the foot 42 toward the inner side in the left-right direction; a lower end surface 43b that extends from the middle part 42b of the foot 42 toward the inner side in the left-right direction; and a front end surface that extends from the downwardly inclined surface 43a of the engaging protrusion 43 to the lower end surface 43b, and is formed parallel to the up-down direction.

[0144] From the planar perspective of the clamping component 40 ( Figure 8 In this configuration, the left and right engaging protrusions 43 protrude in a trapezoidal shape from a portion of the foot portion 42 toward the inner side in the left-right direction. In this case, each engaging protrusion 43 on the left and right sides is missing on one side (rear side) or the other side (front side) in its front-rear direction. The left and right engaging protrusions 43 have an asymmetrical shape with reference to the center line in the width direction of the clamping member 40. Furthermore, the left and right engaging protrusions 43 have a shape that is point-symmetrical to each other.

[0145] In the plane perspective ( Figure 8 The left and right engaging protrusions 43 are positioned in the front-back direction within a range of 50% to 80% relative to the forming range of the foot 42.

[0146] By making the forming range of the engaging protrusion 43 relative to the foot 42 more than 50%, the zipper teeth 24 housed in the storage space 45 of the clamping member 40 can be properly engaged with the left and right engaging protrusions 43 and pressed by the engaging protrusions 43. By making the forming range of the engaging protrusion 43 relative to the foot 42 less than 80%, when the zipper teeth 24 are pressed and move toward the storage space 45 of the clamping member 40, the zipper teeth 24 can smoothly pass over the left and right engaging protrusions 43.

[0147] In the plane perspective ( Figure 8 In this configuration, the left and right engaging protrusions 43 are arranged such that a portion of the engaging protrusions 43 overlaps with each other within their forming range in the front-rear direction. In this case, the left and right engaging protrusions 43 overlap with each other by a ratio of 25% or more and 50% or less relative to the forming range in the front-rear direction of the foot portion 42 or relative to the entire length dimension (dimension in the front-rear direction) from the front edge to the rear edge of the clamping member 40.

[0148] By ensuring that the overlap length of the left and right engaging protrusions 43 in the front-to-back direction is more than 25% of the entire foot portion 42 or the entire clamping member 40, the left and right zipper teeth 24 stored in the storage space portion 45 of the clamping member 40 can be appropriately pressed by the engaging protrusions 43. By ensuring that the overlap length of the left and right engaging protrusions 43 is less than 50% of the entire clamping member 40, the zipper teeth 24 can smoothly pass over the engaging protrusions 43 when they move to the storage space portion 45 of the clamping member 40.

[0149] In the plane perspective ( Figure 8 In this embodiment, each engaging protrusion 43 has: an inclined surface 44a disposed on one side (front or rear) in the front-rear direction of the engaging protrusion 43; an orthogonal surface 44b disposed on the other side (rear or front) in the front-rear direction of the engaging protrusion 43; and a parallel surface 44c disposed between the inclined surface 44a and the orthogonal surface 44b. It should be noted that in this second embodiment, the inclined surface of the engaging protrusion 43 corresponds to the inclined portion of the engaging protrusion described in the "Scope of Request".

[0150] The inclined surface 44a of the engaging protrusion 43 is configured to be inclined relative to the front-rear direction. This inclined surface 44a is described from a planar viewing angle (…). Figure 8 The engagement protrusion 43 has an inclination angle of 30° or more and 60° or less relative to the vertical direction. The orthogonal surface 44b of the engagement protrusion 43 is arranged orthogonally to the vertical direction at the end opposite to the inclination surface 44a in the longitudinal direction. The parallel surface 44c of the engagement protrusion 43 is arranged parallel to the longitudinal direction.

[0151] The maximum width of the left and right engaging protrusions 43 is set to be more than 10% and less than 45% of the width distance between the left and right feet 42. (From the plane perspective) Figure 8 ) or the aforementioned frontal view ( Figure 9 In this case, the shortest distance between the left and right engaging protrusions 43 is set to be smaller than the tooth width L1 of the engaged left and right zipper teeth 24. Furthermore, the left and right engaging protrusions 43 are formed such that the interval between the left and right engaging protrusions 43 is largest at the front and rear ends of the clamping member 40.

[0152] By using the fastening member 2 of this embodiment 2, which includes a first zipper longitudinal beam 21, a second zipper longitudinal beam 22, and a plurality of clamping members 40 as described above, it is possible to obtain approximately the same effect as when using the fastening member 1 of the aforementioned embodiment 1.

[0153] That is, by using the fastening member 2 of this embodiment, the first skin portion 11 and the second skin portion 12 of the skin portion 10 can be connected to each other, covering and smoothly fastening the skin portion 10 to the buffer body 6. Furthermore, the skin portion 10 fastened to the buffer body 6 can be easily removed from the buffer body 6. It should be noted that the method of fastening the skin portion 10 to the buffer body 6 using the fastening member 2 of this embodiment, and the method of removing the skin portion 10 fastened to the buffer body 6, are substantially the same as the method described in the aforementioned embodiment one.

[0154] Specifically, in the fastening component 2 of this embodiment, as described above, a parallel surface 44c is provided in the left and right engaging protrusions 43 (refer to...). Figure 8 Therefore, when the engaged left and right zipper teeth 24 are stored in the storage space 45 of the clamping member 40, the left and right engaging protrusions 43 can be firmly engaged with the left and right zipper teeth 24, and the left and right zipper teeth 24 can be stably pressed by the left and right engaging protrusions 43.

[0155] Furthermore, the left and right engaging protrusions 43 are shaped to be missing on one or the other side in the front-back direction. Therefore, when the zipper teeth 24 are removed from the storage space 45 of the clamping member 40, the zipper teeth 24 can be pulled out more easily from one or the other side in the front-back direction of the clamping member 40.

[0156] (Example 3) Figure 10 , Figure 11 ,and Figure 12 These are, respectively, a perspective view, a plan view, and a front view of the clamping component of the fastening component in Embodiment 3.

[0157] The fastening component 3 of this embodiment includes: a first zipper longitudinal beam 21 and a second zipper longitudinal beam 22, which are installed on the surface component 10 of the vehicle seat; and a plurality of clamping components 50, which are fixed to the buffer body 6. The plurality of clamping components 50 of this embodiment are fixed at intervals along the length direction of the receiving groove 7 at the bottom of the groove of the receiving groove 7 of the buffer body 6.

[0158] like Figures 10-12 As shown, the clamping member 50 of this embodiment 3 has: a flat base 51; a pair of left and right legs 52 extending upward from the upper surface of the base 51; a pair of left and right engaging protrusions 53 protruding from the inner side of each left and right leg 52 toward the other leg 52; and a storage space 55 disposed between the left and right legs 52. In this embodiment 3, the base 51, the pair of legs 52, and the storage space 55 of the clamping member 50 are substantially the same as those of the clamping member 30 of the aforementioned embodiment 1. Therefore, the leg 52 has a base end portion 52a, a middle portion 52b, and a front end portion 52c.

[0159] Each of the left and right engaging protrusions 53 protrudes inward in the left and right direction from the inner side of the middle portion 52b and the front end portion 52c of the foot portion 52. The engaging protrusions 53 of this embodiment are viewed from the front of the clamping member 50. Figure 12 In this case, it is formed to protrude in a roughly triangular shape from the inner side of the foot 52. Similar to the case in Embodiment 1 described above, in the frontal view ( Figure 12The left and right engaging protrusions 53 each have: a downwardly inclined surface 53a that slopes downward from the front end 52c of the foot 52 toward the inner side in the left-right direction; a lower end surface 53b that extends from the middle part 52b of the foot 52 toward the inner side in the left-right direction; and a front end surface that is formed parallel to the up-down direction from the downwardly inclined surface 53a of the engaging protrusion 53 to the lower end surface 53b.

[0160] From the planar perspective of the clamping component 50 ( Figure 11 The left and right engaging protrusions 53 extend in a trapezoidal shape from the entire front-rear direction of the foot 52 toward the inner side in the left-right direction. The left and right engaging protrusions 53 have a linearly symmetrical shape with reference to the center line in the width direction of the clamping member 50. The left and right engaging protrusions 53 are arranged such that the entire engaging protrusion 53 overlaps each other in the front-rear direction.

[0161] In the plane perspective ( Figure 11 Below, each of the left and right engaging protrusions 53 has: an inclined surface 54a disposed at both ends of the engaging protrusion 53 in the front-rear direction; and a parallel surface 54b disposed between the two inclined surfaces. It should be noted that, in this third embodiment, the inclined surface 54a of the engaging protrusion 53 corresponds to the inclined portion of the engaging protrusion described in the "Scope of Request". Furthermore, one inclined surface 54a and the other inclined surface 54a of the engaging protrusion 53 correspond to the first inclined portion and the second inclined portion, respectively.

[0162] The inclined surface 54a and parallel surface 54b of the engaging protrusion 53 are respectively formed as flat surfaces. The inclined surface 54a of the engaging protrusion 53 is shown in the plane view (…). Figure 11 ( ) below, tilted at an angle of more than 30° and less than 60° relative to the front and rear directions.

[0163] The parallel surface 54b of the engaging protrusion 53 is configured to be parallel to the front-rear direction. The parallel surface 54b of the engaging protrusion 53 is continuously disposed in a range of 50% to 90% relative to the length of the entire foot 52 or the entire clamping member 50 in the front-rear direction.

[0164] By making the area of ​​the parallel surface 54b of the engaging protrusion 53 in the front-rear direction more than 50% of the entire foot 52 or the entire clamping member 50, the left and right zipper teeth 24 housed in the storage space 55 of the clamping member 50 can be appropriately pressed by the engaging protrusion 53. By making the area of ​​the parallel surface 54b in the front-rear direction less than 90% of the entire foot 52 or the entire clamping member 50, inclined surfaces 54a can be appropriately provided at the front and rear ends of the engaging protrusion 53.

[0165] In the plane perspective ( Figure 11Under this condition, the maximum width of the left and right engaging protrusions 53 is set to be more than 10% and less than 45% of the width distance between the left and right feet 52. Furthermore, in the planar view ( Figure 11 ) or the aforementioned frontal view ( Figure 12 In this case, the shortest distance between the left and right engaging protrusions 53 is set to be smaller than the tooth width L1 of the engaged left and right zipper teeth 24. Furthermore, the left and right engaging protrusions 53 are formed such that the interval between the left and right engaging protrusions 53 is largest at the front and rear ends of the clamping member 50.

[0166] By using the fastening member 3 of this embodiment 3, which includes a first zipper longitudinal beam 21, a second zipper longitudinal beam 22, and a plurality of clamping members 50 as described above, it is possible to obtain approximately the same effect as when using the fastening member 3 of the aforementioned embodiments 1 and 2.

[0167] Specifically, in the fastening component 3 of this embodiment, a parallel surface 54b is provided in the left and right engaging protrusions 53 (see reference). Figure 11 Therefore, when the engaged left and right zipper teeth 24 are stored in the storage space 55 of the clamping member 50, the left and right engaging protrusions 53 can engage more firmly with the left and right zipper teeth 24, and the left and right zipper teeth 24 can be stably pressed by the left and right engaging protrusions 53.

[0168] (Example 4) Figure 13 This is a perspective view schematically showing the clamping component of Embodiment 4.

[0169] The fastening component 4 in this embodiment 4 includes: a first zipper longitudinal beam 21 and a second zipper longitudinal beam 22, which are installed on the surface component 10 of the vehicle seat; and a clamping component 60, which is made of synthetic resin and is fixed to the buffer body 6. The clamping component 60 is fixed to the bottom of the groove of the elongated receiving groove 7 of the buffer body 6 along the length direction of the receiving groove 7.

[0170] The clamping member 60 of this embodiment 4 has: a plurality of clamping parts 61; and a connecting part 62, which connects two clamping parts 61 adjacent to each other in the front-back direction.

[0171] The clamping part 61 in this fourth embodiment includes: a first clamping part 61a, which has the same shape as a clamping member 60 in the first embodiment described above; and a second clamping part 61b, which has a shape symmetrical to the first clamping part 61a. In this case, the first clamping part 61a and the second clamping part 61b are formed symmetrically to each other with reference to a plane orthogonal to the front-back direction. Furthermore, the first clamping part 61a and the second clamping part 61b are alternately arranged in the front-back direction within the clamping member 60.

[0172] It should be noted that in the clamping member 60 of this embodiment, the configuration (setting order) of the first clamping part 61a and the second clamping part 61b is not particularly limited. In addition, the clamping member 60 can be formed by connecting only a plurality of first clamping parts 61a through the connecting part 62, or by connecting only a plurality of second clamping parts 61b through the connecting part 62.

[0173] Each connecting portion 62 of the clamping member 60 is arranged in a straight line along the front-back direction between the first clamping portion 61a and the second clamping portion 61b. The connecting portion 62 is formed such that its cross-section orthogonal to the front-back direction has a rectangular shape and can be bent in the vertical and horizontal directions.

[0174] The first clamping portion 61a, the second clamping portion 61b, and the connecting portion 62 of the clamping member 60 are integrally formed, for example, by injection molding. It should be noted that the method and means of manufacturing the clamping member are not particularly limited in this invention. Furthermore, in this fourth embodiment, the first clamping portion 61a and the second clamping portion 61b, as well as the connecting portion 62, of the clamping member 60 can also be formed from separate parts. A clamping member 60 in which the connecting portion 62 is formed from a separate part (e.g., a monofilament) can be manufactured, for example, by insert molding.

[0175] The clamping member 60 has a connecting portion 62, which allows the clamping member 60, which is longer in the front-to-back direction, to be easily bent in the vertical and horizontal directions. Therefore, even if the receiving groove portion 7 provided in the buffer body 6 includes a curved portion that bends in the vertical and / or horizontal directions, the clamping member 60 of this embodiment four can be stably fixed in the receiving groove portion 7 along the receiving groove portion 7.

[0176] By using the fastening member 4 of this embodiment 4, which includes the first zipper longitudinal beam 21, the second zipper longitudinal beam 22, and the aforementioned clamping member 60, approximately the same effect as when using the fastening member 1 of the first embodiment is achieved.

[0177] Specifically, in the fastening member 4 of this embodiment, a clamping member 60 is formed by connecting multiple first clamping parts 61a and second clamping parts 61b via a connecting part 62. Therefore, in order to fix the clamping member 60 to the buffer body 6, for example, compared with the clamping member 30 of the aforementioned embodiment 1, it is easier to install the clamping member 60 onto the molding die before the buffer body 6 is foamed.

[0178] (Example 5) Figure 14 This is a perspective view schematically showing the clamping component of Embodiment 5.

[0179] The fastening component 5 in this embodiment 5 includes: a first zipper longitudinal beam 21 and a second zipper longitudinal beam 22, which are installed on the surface component 10 of the vehicle seat; and a clamping component 70, which is made of synthetic resin and is fixed to the buffer body 6. The clamping component 70 is fixed to the bottom of the groove of the elongated receiving groove 7 of the buffer body 6 along the length direction of the receiving groove 7.

[0180] The clamping member 70 of this embodiment 5 has: a flat base 71; a pair of left and right feet 72 extending upward from the upper surface of the base 71; a pair of left and right engaging protrusions 73 protruding from the inner side of each left and right foot 72 toward the other foot 72; and a storage space 75 disposed between the left and right feet 72.

[0181] In this fifth embodiment, the base 71, the pair of feet 72, and the storage space 75 of the clamping member 70 are longer in the front-back direction than the clamping member 30 of the first embodiment, but apart from the difference in length, they are substantially the same as the base 31, the pair of feet 32, and the storage space 35 of the clamping member 30 of the first embodiment.

[0182] In the clamping member 70 of this embodiment 5, each of the left and right engaging protrusions 73 protrudes inward in the left-right direction from the inner side of the middle and front ends of the foot 72. In the first embodiment, the engaging protrusion 73, viewed from the front (not shown) of the clamping member 70, is formed as a generally triangular protrusion from the inner side of the foot 72. In this case, the generally triangular engaging protrusion 73 has: a downwardly sloping surface 73a that slopes downward inward in the left-right direction from the front end of the foot 72; a lower end surface 73b that extends inward in the left-right direction from the middle of the foot 72; and a front end surface that is formed parallel to the vertical direction from the downwardly sloping surface 73a to the lower end surface 73b of the engaging protrusion 73.

[0183] In a planar view (not shown) of the clamping member 70, each of the left and right engaging protrusions 73 protrudes in a trapezoidal shape from the entire front-rear direction of the foot 72 toward the inner side in the left-right direction, with the front and rear edges of the engaging protrusion 73 forming the upper and lower bases, respectively. Furthermore, in the same planar view (not shown), the engaging protrusion 73 has an inclined surface formed from the front edge to the rear edge. This inclined surface is continuously formed from the front edge to the rear edge of the engaging protrusion 73 at a fixed inclination angle (e.g., an inclination angle of 20° or less).

[0184] In the clamping member 70 having left and right engaging protrusions 73, the interval between the left and right engaging protrusions 73 is formed to a fixed size over the entire range from the front edge to the rear edge of the engaging protrusions 73, and is formed at an angle relative to the front-rear direction. It should be noted that, in this fifth embodiment, the engaging protrusions 73, from the planar view of the clamping member 70, can protrude in a generally triangular shape from the inner side of the foot 72 as in the first embodiment described above, or in a trapezoidal shape from the inner side of the foot 72 as in the second or third embodiment described above.

[0185] By using the fastening member 5 of this embodiment 5, which includes the first zipper longitudinal beam 21, the second zipper longitudinal beam 22, and the aforementioned clamping member 70, it is possible to obtain approximately the same effect as when using the fastening member 1 of the aforementioned embodiment 1.

[0186] In particular, in the fastening member 5 of this embodiment, the clamping member 70 is formed to be longer in the front-to-back direction. Therefore, for example, when the receiving groove 7 provided in the buffer body 6 is formed in a straight line, it is possible to easily install the clamping member 70 into the molding die of the buffer body 6 before the buffer body 6 is foamed.

[0187] Furthermore, when the engaged left and right zipper teeth 24 are housed in the storage space 75 of the clamping member 70 of this embodiment, the left and right engaging protrusions 73 can engage with the left and right zipper teeth 24 in a longer and more stable manner in the front-back direction. Therefore, it is possible to prevent or suppress the left and right zipper teeth 24 from disengaging from the storage space 75 of the clamping member 70.

[0188] It should be noted that the present invention is not limited to the embodiments described above. Various modifications can be made as long as the invention has the same structure and performs the same function.

[0189] For example, in the fastening components 1 to 5 of Embodiments 1 to 5, as described above, the first zipper longitudinal beam 21 and the second zipper longitudinal beam 22 are formed into a back-side-use type zipper longitudinal beam by sewing a plurality of continuous zipper teeth 24 in a coil shape to the side edge of the zipper tape 23.

[0190] However, in this invention, the first and second zipper longitudinal beams can also be formed as so-called concealed zipper longitudinal beams. The concealed zipper longitudinal beam is formed by folding back the side edge of the zipper tape to give the zipper tape a U-shaped cross-section, and by sewing multiple zipper teeth to the folded side edge of the tape.

[0191] It should be noted that when the first zipper beam and the second zipper beam are formed as concealed zipper beams, when the zipper teeth of the first zipper beam and the second zipper beam are made to mesh and engage with each other and be engaged with the clamping member, the storage space of the clamping member stores and retains the portion of the meshed zipper teeth of the first zipper beam and the second zipper beam and the side edge of the zipper tape.

[0192] Furthermore, in this invention, in the first and second zipper longitudinal beams, a plurality of zipper teeth having individual, separate, and independent shapes, for example, obtained by injection molding of synthetic resin, can be provided on the zipper tape instead of a plurality of continuously coiled zipper teeth 24. Alternatively, a plurality of metal zipper teeth obtained by stamping metal wire or sheet metal can be installed on the zipper tape instead of a plurality of continuously coiled zipper teeth 24.

[0193] Furthermore, in Examples 1 to 5, the application of fastening components 1 to 5 to vehicle seats such as automobiles was described. However, the fastening components of the present invention are applicable not only to vehicle seats, but also to various products including, for example, seats in trains, airplanes, or ships, seats used in schools or office buildings, cushions for sports equipment, and furniture such as sofas or beds for residences.
