[0007] Problems to be Solved by the Invention

[0008] In the skin material mounting device as described above, since a pulling force is applied to the clip from the skin material via the hook, if this pulling force is too large, the clip may come off from the cushioning material. Therefore, it is desired to improve the fixing strength of the clip with respect to the cushioning material.

[0009] An object of the present invention is to provide a clip and a clip connection body capable of improving the fixing strength with respect to a cushioning material.

[0010] Solutions to the Problems

[0011] (First Technical Solution)

[0012] The first technical solution of the present invention provides a clip, which includes: a sheet portion buried in a cushioning material; and a clip main body portion that can be engaged with a hook attached to a skin material and is attached to the sheet portion. The clip main body portion includes: a base portion having an adhesive surface bonded to the sheet portion; a pair of leg portions erected from the base portion and opposed to each other in the left-right direction; and a pair of claw portions provided on the pair of leg portions and protruding in a direction approaching each other in the left-right direction. The size of the sheet portion in the left-right direction is larger than the size of the adhesive surface of the base portion in the left-right direction, and the size of the adhesive surface of the base portion in the left-right direction is smaller than the maximum outer size of the clip main body portion in the left-right direction determined by the pair of leg portions.

[0013] In such a structure, a pair of claw portions of the clip main body portion can engage with a hook inserted between the pair of leg portions, and a sheet portion embedded in the cushioning material can be closely attached to the cushioning material. Further, by setting the size in the left-right direction of the base portion with respect to the bonding surface of the sheet portion, the maximum outer size in the left-right direction of the clip main body portion based on the pair of leg portions, and the size in the left-right direction of the sheet portion as described above, it is possible to largely ensure the close contact area of the sheet portion with respect to the cushioning material around the clip main body portion. Accordingly, even when a pulling force is applied to the clip via the hook, the sheet portion is hardly peeled off from the cushioning material, and thus the clip is not easily detached from the cushioning material. Thereby, the fixing strength of the clip with respect to the cushioning material can be improved.

[0014] (Second Technical Solution)

[0015] In the clip according to the first technical solution of the present invention, it is preferable that each of the pair of leg portions includes: a first extension portion that extends upward from the base portion while extending in a direction separating from each other in the left-right direction; and a second extension portion that extends upward in a range from the first extension portion to the claw portion, and a space into which a part of the cushioning material can enter is formed between the first extension portion and the sheet portion.

[0016] According to such a structure, it is possible to ensure an insertion space for the hook between the pair of leg portions while appropriately ensuring the close contact area of the sheet portion with respect to the cushioning material around the clip main body portion.

[0017] (Third Technical Solution)

[0018] In the clip according to the first technical solution or the second technical solution of the present invention, it is preferable that the size of the sheet portion in the left-right direction is 2 times or more and 3 times or less of the maximum outer size in the left-right direction of the clip main body portion determined by the pair of leg portions.

[0019] According to such a structure, it is possible to improve the fixing strength of the clip with respect to the cushioning material while ensuring the strength of the cushioning material.

[0020] (Fourth Technical Solution)

[0021] In the clip according to any one of the first to third technical solutions of the present invention, the sheet portion is preferably a non-woven fabric.

[0022] In such a structure, the close contact property of the sheet portion with respect to the cushioning material can be appropriately improved by the fine pores present in the non-woven fabric constituting the sheet portion.

[0023] (Fifth Technical Solution)

[0024] The fifth technical solution of the present invention provides a clip connecting body, wherein the clip connecting body includes: a plurality of clips, which are described in any one of the first to fourth technical solutions and are arranged along an arbitrary arrangement direction; and a clip connecting portion that connects the plurality of clips to each other and is elastically deformable.

[0025] In such a structure, the same effects as those of the clips in any one of the above first to fifth technical solutions can be achieved. In addition, since the clip connecting body has a sheet portion in each clip, by elastically deforming the clip connecting portion, the overall shape of the clip connecting body can follow the shape of the groove of the cushioning material (for example, a bent shape).

[0026] (Sixth technical solution)

[0027] In the clip connecting body according to the fifth technical solution of the present invention, preferably, the sheet portions of the plurality of clips adjacent to each other are arranged at intervals from each other.

[0028] In such a structure, in various arrangements of the clip connecting body, since the sheet portions of the respective clips are not likely to overlap each other, the adhesion of each clip to the cushioning material can be appropriately maintained. Description of the drawings

[0033] Figure 5 It is a diagram schematically showing a situation where a hook is engaged with the clip of the above embodiment. Detailed implementation manners

[0034] Hereinafter, an embodiment of the present invention will be described based on the drawings.

[0035] As Figure 1As shown in the figure, the skin material installation device 1 of the present embodiment is used to install the skin material 3 on the cushioning material 2 such as a vehicle seat. The skin material installation device 1 includes: a hook 4 which is installed on the skin material 3; and a clip connecting body 50 which is provided in the groove 21 of the cushioning material 2. By engaging the hook 4 with the clip connecting body 50, the skin material 3 can be installed on the cushioning material 2.

[0036] The cushioning material 2 is a synthetic resin urethane foam material such as foamed polyurethane formed into the shape of a seat. A groove 21 for installing the clip 5 is formed in the cushioning material 2. The groove 21 has an opening on the surface of the cushioning material 2 and extends along an arbitrary direction on the surface of the cushioning material 2. In addition, in the cushioning material 2, a bottom surface 213 and a pair of side wall surfaces 211, 212 facing each other are formed by the groove 21.

[0037] The skin material 3 is a sheet covering the surface of the cushioning material 2, for example, a synthetic resin fabric sheet. The edge portion 31 of the skin material 3 is installed on the hook 4 by sewing or the like.

[0038] Refer to Figures 1 to 3 to describe the structure of the skin material installation device 1.

[0039] Hereinafter, in the description of the structure of the skin material installation device 1, the state in which the hook 4 is engaged with the clip 5 is used as a reference, and the three-axis directions of XYZ are used (refer to Figure 1 ). For example, the length direction of the skin material installation device 1 is set as the X direction, the left-right direction of the skin material installation device 1 is set as the Y direction, and the up-down direction of the skin material installation device 1 is set as the Z direction. In addition, in the state where the skin material 3 is installed on the cushioning material 2 by the skin material installation device 1 (refer to Figure 1 ), the X direction corresponds to the length direction of the groove 21 of the cushioning material 2, the Y direction corresponds to the width direction of the groove 21, and the Z direction corresponds to the depth direction of the groove 21. In addition, for the convenience of description, the direction on one side (upper side) toward the Z direction is set as the +Z direction, the direction on the other side (lower side) toward the Z direction is set as the -Z direction, and the groove 21 is set as a groove opening in the cushioning material 2 in the +Z direction.

[0040] As Figure 1 shown, the hook 4 includes: a mounting portion 41 on which the edge portion 31 of the skin material 3 is mounted; and a hook main body portion 42 which is fixed to the mounting portion 41.

[0041] In the present embodiment, the mounting portion 41 is a sheet member such as non-woven fabric arranged along the XZ plane. In the mounting portion 41, for example, the edge portions 31 of two skin materials 3 are stacked, and the mounting portion 41 and the edge portion 31 of the skin material 3 are sewn together.

[0042] The hook main body 42 has: a base portion 421 in which the -Z side end portion of the mounting portion 41 is buried; a pair of jig projections 422 provided on both sides of the base portion 421 in the Y direction; and a pair of engaging projections 423 provided on both sides of the base portion 421 in the Y direction at a position closer to the -Z side than the pair of jig projections 422.

[0043] Each of the pair of jig projections 422 of the pair of jig projections 422 projects outward from the base portion 421 in the Y direction and forms a recess 422A that opens in the +Z direction between the base portion 521. Any jig for operating the hook 4 can be inserted into the recess 422A.

[0044] Each of the pair of engaging projections 423 of the pair of engaging projections 423 projects outward from the base portion 421 in the Y direction at a portion closer to the -Z side than the jig projection 422 and together forms an anchor shape that engages with the clip 5.

[0045] In addition, in the present embodiment, the hook main body 42 is a resin product injection-molded with the mounting portion 41 as an insert. In addition, the hook main body 42 has a shape that continuously or intermittently extends in the X direction so as to be able to engage with each clip 5 of the clip connecting body 50.

[0046] As Figure 2 shown, the clip connecting body 50 includes a plurality of clips 5 and a clip connecting portion 53 that connects the plurality of clips 5 to each other. In addition, hereinafter, the description will be based on the state in which the plurality of clips 5 are arranged along the X direction. In addition, hereinafter, one clip 5 will be described as an example, but the other clips 5 also have the same structure.

[0047] As Figure 1 shown, the clip 5 includes a sheet portion 51 buried in the cushioning material 2 and a clip main body 52 that can engage with the hook 4 and is mounted on the sheet portion 51. Refer to Figure 3 to describe the structure of the clip 5.

[0048] The sheet portion 51 is a sheet member disposed along the XY plane. The specific material of the sheet portion 51 is not particularly limited, and a non-woven fabric is preferably used. The sheet portion 51 extends to both sides of the clip main body 52 in the Y direction and is buried in the cushioning material 2 below the bottom surface 213 of the groove 21 of the cushioning material 2 and on both sides of the groove 21 in the Y direction. In addition, although not shown, one or more through holes may be formed in the sheet portion 51.

[0049] The clip main body 52 includes a base portion 521 mounted on the sheet portion 51, a pair of legs 522 erected from the base portion 521 and opposed to each other in the Y direction, and a pair of claw portions 525 provided on the pair of legs 522.

[0050] The base 521 is mounted on a partial area of the surface 511 of the sheet portion 51 facing the +Z side. Specifically, the base 521 has an adhesive surface 521A that is adhered to the surface 511 of the sheet portion 51. Here, the dimension W3 of the sheet portion 51 in the Y direction is larger than the dimension W1 of the adhesive surface 521A of the base 521 in the Y direction.

[0051] In addition, there is no particular limitation on the method of adhering the base 521 to the sheet portion 51, and any adhesive can be used. That is, the adhesive surface 521A of the base 521 is adhered to the sheet portion 51 via the adhesive layer 54.

[0052] Each of the pair of legs 522 has a first extension portion 523 that extends in the +Z direction from the base 521 and also extends outward in the Y direction (i.e., the direction of mutual separation in the Y direction), and a second extension portion 524 that extends in the +Z direction within the range from the first extension portion 523 to the claw portion 525.

[0053] Here, the first extension portion 523 depicts a curved shape that extends in the +Z direction from the base 521 and also goes outward in the Y direction. The first extension portion 523 faces the sheet portion 51, and a space S is formed between the first extension portion 523 and the sheet portion 51 into which a part of the cushioning material 2 can enter. In addition, in the present embodiment, the maximum outer dimension W2 of the clip main body portion 52 in the Y direction determined by the pair of legs 522 corresponds to the dimension between the outer side surfaces in the Y direction of the respective second extension portions 524 of the pair of legs 522.

[0054] Each of the pair of claw portions 525 projects from the tip of the respective second extension portion 524 of the pair of legs 522 toward the inner side in the Y direction and the -Z direction. A gap is formed between the pair of claw portions 525 into which the hook 4 can be inserted.

[0055] In the above clip 5, the dimension W1 of the adhesive surface 521A of the base 521 in the Y direction is smaller than the maximum outer dimension W2 of the clip main body portion 52 in the Y direction based on the pair of legs 522.

[0056] In addition, in the clip 5, it is preferable that the dimension W3 of the sheet portion 51 in the Y direction is larger than the maximum outer dimension W2 of the clip main body portion 52 in the Y direction based on the pair of legs 522. Specifically, the dimension W3 of the sheet portion 51 in the Y direction is preferably 2 times or more and 3 times or less of the maximum outer dimension W2 of the clip main body portion 52 in the Y direction based on the pair of legs 522.

[0057] In addition, in the above clip 5, the dimension of each element in the X direction can be set arbitrarily. In addition, as Figure 2 shown, it is preferable that the dimension of the sheet portion 51 in the X direction and the dimension of the clip main body portion 52 in the X direction are of the same degree.

[0058] The clip connecting portion 53 connects a plurality of clips 5 arranged in an arbitrary direction. Specifically, the clip connecting portion 53 includes a plurality of base connecting portions 531 respectively disposed between the bases 521 of adjacent clips 5 and a linear member 532 that continuously penetrates the plurality of clips 5 and the plurality of base connecting portions 531.

[0059] The base connecting portion 531 has a rod shape extending along the X direction so as to connect the bases 521 of adjacent clips 5 to each other.

[0060] The linear member 532 is, for example, a wire. By setting the linear member 532 as an insert, the plurality of clips 5 and the plurality of base connecting portions 531 can be integrally injection-molded.

[0061] In the clip connecting body 50 described above, the clip connecting portion 53 has a certain degree of flexibility. For example, as Figure 4 shown, by bending the clip connecting portion 53, the plurality of clips 5 can be arranged along the bending direction.

[0062] (Method of setting the clip connecting body)

[0063] An example of a method of setting the clip connecting body 50 of the present embodiment in the cushioning material 2 will be briefly described.

[0064] First, the clip connecting body 50 is placed relative to the groover of the mold for the cushioning material 2. The groover is a mold for forming the groove 21 of the cushioning material 2 and is arranged at a position corresponding to the groove 21.

[0065] Next, the material of the cushioning material 2 is poured into the mold of the cushioning material 2 and foamed and cured, thereby forming the cushioning material 2. At this time, the material of the cushioning material 2 fills the surrounding space of the clip connecting body 50 including the space S of each clip 5.

[0066] After that, the groover and the mold are removed from the cushioning material 2. At this time, the range where the groover exists in the mold of the cushioning material 2 appears as the groove 21. Thus, as Figure 1 shown, each clip 5 of the clip connecting body 50 is set in the groove 21.

[0067] (Method of installing the skin material)

[0068] The method of installing the skin material using the skin material installation tool 1 of the present embodiment will be briefly described.

[0069] First, an operator prepares a hook 4 with a skin material 3 installed thereon and a cushioning material 2 with a clip connecting body 50 set in the groove 21, and arranges the skin material 3 so as to cover the cushioning material 2.

[0070] Thereafter, the hook 4 is inserted into the groove 21 of the cushioning material 2, and a pressing force in the -Z direction is applied to the hook 4 by any pressing member (such as a jig or an automatic machine).

[0071] For example, when an operator uses a jig, by inserting the jig into the recess 422A formed by any one of the jig protrusions 422 of the hook 4, a pressing force in the -Z direction can be applied to the hook 4.

[0072] Alternatively, when using any automatic machine, the operation part 71 of the automatic machine is inserted into the hole part 22 formed in the region corresponding to the gap between adjacent clips 5 on the bottom surface 213 of the groove 21 of the cushioning material 2 (see Figure 5 ). Moreover, the operation part 71 can hold the jig protrusion 422 of the hook 4 and apply a pressing force in the -Z direction to the hook 4.

[0073] The hook 4 pressed by any pressing member is pressed against the clip main body part 52 of each clip 5. Moreover, the hook 4 is guided by a pair of claw parts 525 while elastically deforming a pair of leg parts 522. After a pair of engaging protrusions 423 of the hook 4 pass between a pair of claw parts 525, the pair of leg parts 522 return to their original shapes, and the pair of engaging protrusions 423 engage with the pair of claw parts 525. At this time, each of the pair of claw parts 525 of the pair of claw parts 525 is in a state of entering the space between the jig protrusion 422 and the engaging protrusion 423 of the hook 4.

[0074] Thus, the hook 4 is fixed to the clip 5. Thereby, the skin material 3 can be attached to the cushioning material 2.

[0075] (Effect of this embodiment)

[0076] In the clip 5 of this embodiment, as described above, it includes a sheet part 51 buried in the cushioning material 2 and a clip main body part 52 that can engage with the hook 4 attached to the skin material 3 and is attached to the sheet part 51. The clip main body part 52 includes: a base part 521 having an adhesive surface 521A bonded to the sheet part 51; a pair of leg parts 522 erected from the base part 521 and opposed to each other in the left-right direction (Y direction); and claw parts 525 provided on the pair of leg parts 522 and protruding in the direction of approaching each other in the left-right direction (inside the Y direction). The Y-direction dimension W3 of the sheet part 51 is larger than the Y-direction dimension W1 of the adhesive surface 521A of the base part 521, and the Y-direction dimension W1 of the adhesive surface 521A of the base part 521 is smaller than the maximum outer dimension W2 of the Y-direction outer dimension of the clip main body part 52 determined by the pair of leg parts 522.

[0077] In such a structure, a pair of claw portions 525 of the clip body portion 52 can engage with the hook 4 inserted between the pair of leg portions 522, and the sheet portion 51 embedded in the cushioning material 2 can be in close contact with the cushioning material 2. Further, by setting the Y-direction dimension W1 of the bonding surface 521A where the base portion 521 is bonded to the sheet portion 51, the maximum outer dimension W2 in the Y direction of the clip body portion 52 based on the pair of leg portions 522, and the Y-direction dimension W3 of the sheet portion 51 as described above, it is possible to ensure a relatively large area of close contact between the sheet portion 51 and the cushioning material 2 around the clip body portion 52. Accordingly, even when a pulling force is applied to the clip 5 via the hook 4, the sheet portion 51 is hardly peeled off from the cushioning material 2, and thus the clip 5 is not easily detached from the cushioning material 2. Thereby, the fixing strength of the clip 5 with respect to the cushioning material 2 can be improved.

[0078] In addition, in the present embodiment, by suppressing the area of close contact between the sheet portion 51 and the base portion 521, it is possible to ensure a relatively large area of close contact between the sheet portion 51 and the cushioning material 2 around the clip body portion 52. Here, the bonding strength based on a normal adhesive is stronger than the close contact strength based on the foamed resin constituting the cushioning material 2. Therefore, even if the bonding area between the sheet portion 51 and the base portion 521 is suppressed to be small, it is not likely to affect the overall strength of the clip 5, and the fixing strength of the clip 5 can be improved without problems.

[0079] In the clip 5 of the present embodiment, each of the leg portions 522 in the pair of leg portions 522 includes a first extension portion 523 that extends upward (+Z side) from the base portion 521 and extends in a direction of separating from each other in the left-right direction (outer side in the Y direction), and a second extension portion 524 that extends in the +Z side within the range from the first extension portion 523 to the claw portion 525. A space S into which a part of the cushioning material 2 can enter is formed between the first extension portion 523 and the sheet portion 51. According to such a structure, while ensuring the insertion space for the hook 4 between the pair of leg portions 522, it is possible to appropriately ensure the area of close contact between the sheet portion 51 and the cushioning material 2 around the clip body portion 52.

[0080] In the clip 5 of the present embodiment, the Y-direction dimension W3 of the sheet portion 51 is 2 times or more and 3 times or less the maximum outer dimension W2 in the Y direction of the clip body portion 52 determined by the pair of leg portions 522.

[0081] In such a structure, by making the Y-direction dimension W3 of the sheet portion 51 2 times or more the maximum outer dimension W2 in the Y direction of the clip body portion 52 based on the pair of leg portions 522, it is possible to sufficiently ensure the area of close contact between the sheet portion 51 and the cushioning material 2.

[0082] In addition, by making the Y-direction dimension W3 of the sheet portion 51 equal to or less than three times the maximum outer dimension W2 in the Y direction of the clip main body portion 52 based on the pair of leg portions 522, the strength of the cushioning material 2 can be ensured.

[0083] Assume that when the Y-direction dimension W3 of the sheet portion 51 is larger than three times the maximum outer dimension W2 in the Y direction of the clip main body portion 52 based on the pair of leg portions 522, the adhesion area of the sheet portion 51 with respect to the cushioning material 2 becomes larger. However, when the cushioning material 2 is foamed and formed around the sheet portion 51 of such a size, a large amount of the material of the cushioning material 2 is attracted by the sheet portion 51, and thus voids (bubbles) in the cushioning material 2 are likely to occur. As a result, the strength of the cushioning material 2 is reduced.

[0084] In the present embodiment, instead of simply increasing the Y-direction dimension W3 of the sheet portion 51, the Y-direction dimension W3 of the sheet portion 51 is suppressed to be equal to or less than three times the maximum outer dimension W2 in the Y direction of the clip main body portion 52 based on the pair of leg portions 522, and on this basis, the adhesion area of the sheet portion 51 with respect to the cushioning material 2 is ensured. Therefore, while ensuring the strength of the cushioning material 2, the fixing strength of the clip 5 with respect to the cushioning material 2 can be improved.

[0085] In the clip 5 of the present embodiment, the sheet portion 51 is a non-woven fabric. In such a structure, the adhesion of the sheet portion 51 with respect to the cushioning material 2 can be appropriately improved through the fine pores existing in the non-woven fabric constituting the sheet portion 51.

[0086] The clip connector 50 of the present embodiment includes a plurality of clips 5 arranged along an arbitrary arrangement direction and a clip connecting portion 53 that connects the plurality of clips 5 to each other and is elastically deformable.

[0087] In such a structure, the same effects as those of the above-described clip 5 can be achieved. In addition, since the clip connector 50 has the sheet portion 51 in each clip 5, by elastically deforming the clip connecting portion 53, the overall shape of the clip connector 50 can follow the shape (e.g., a bent shape) of the groove 21 of the cushioning material 2.

[0088] In the clip connector 50 of the present embodiment, the sheet portions 51 of the clips 5 adjacent to each other are arranged at intervals therebetween. In such a structure, in various arrangements of the clip connector 50, since the sheet portions 51 of the respective clips 5 are not likely to overlap each other, the adhesion of each clip 5 with respect to the cushioning material 2 can be appropriately maintained.

[0089] (Modification example)

[0090] In the above-described embodiment, the preferred range of the dimension W3 of the sheet portion 51 in the Y direction is described, but the present invention is not limited thereto. That is, the dimension W3 of the sheet portion 51 in the Y direction can be arbitrarily set within a range larger than the dimension W1 of the bonding surface 521A of the base portion 521 in the Y direction.

[0091] In addition, the sheet portion 51 may not be a non-woven fabric, but may be any sheet member such as a fabric.

[0092] In the clip connecting body 50 of the above-described embodiment, each clip 5 includes a sheet portion 51, but a single sheet portion 51 may be shared by a plurality of clips 5.

[0093] In addition, in the above-described embodiment, the clip connecting body 50 in which a plurality of clips 5 are connected is described, but it may also be used in a state where a plurality of clips 5 are separately divided.

[0094] In the above-described embodiment, the clip connecting portion 53 has a plurality of base connecting portions 531 and a linear member 532, but the present invention is not limited thereto. For example, the clip connecting portion 53 may be composed of a linear member 532 such as a wire without having a plurality of base connecting portions 531. Or, the clip connecting portion 53 may be composed of a plurality of base connecting portions 531 without having the linear member 532. In addition, the clip connecting body 50 may connect portions of each clip 5 other than the base portion 521 to each other.

[0095] In the above-described embodiment, the first extension portion 523 of the leg portion 522 has a curved shape, but the present invention is not limited thereto. For example, the first extension portion 523 may have a linear shape that extends in the +Z direction from the base portion 521 and then goes outward in the Y direction.

[0096] In addition, in the above-described embodiment, the maximum outer dimension W2 of the clip main body portion 52 in the Y direction based on the pair of leg portions 522 corresponds to the dimension between the outer side surfaces in the Y direction of the second extension portions 524 of the pair of leg portions 522, but the present invention is not limited thereto. That is, the maximum outer dimension W2 of the clip main body portion 52 in the Y direction based on the pair of leg portions 522 only needs to be the maximum dimension among the dimensions between the outer side surfaces in the Y direction of any portions of the pair of leg portions 522.
