[0009] [Description of the embodiments of the present disclosure] First, the embodiments of the present disclosure will be listed and described.

[0010] The wiring member of the present disclosure is as follows.

[0011] (1) A wiring member comprising a first sheet material, a second sheet material superimposed on the first sheet material, and a fixed linear transmission member and a free linear transmission member positioned between the first sheet material and the second sheet material, wherein the second sheet material is fixed to the first sheet material by a first fixing portion and a second fixing portion spaced from the first fixing portion, the fixed linear transmission member is fixed to the first sheet material between the first fixing portion and the second fixing portion, and the free linear transmission member is disposed between the first sheet material and the second sheet material in a state where it is arranged in parallel to the fixed linear transmission member.

[0012] According to this wiring member, the detached linear transmission member is arranged in parallel with the fixed linear transmission member, and is arranged between the first sheet material and the second sheet material in a state in which the path is restricted by the fixed linear transmission member. Therefore, the path can be restricted between the first sheet material and the second sheet material even if the detached linear transmission member is not fixed to the first sheet. This makes it easy to manufacture a wiring member that keeps multiple linear transmission members flat.

[0013] (2) In the wiring member of (1), the fixed linear transmission member may include a first fixed linear transmission member and a second fixed linear transmission member fixed in parallel and spaced apart from each other between the first fixed portion and the second fixed portion, and the free linear transmission member may include an intermediate free linear transmission member disposed between the first fixed linear transmission member and the second fixed linear transmission member. This allows the intermediate free linear transmission member to be accommodated between the first fixed linear transmission member and the second fixed linear transmission member.

[0014] (3) In the wiring member of (1) or (2), the first sheet material and the second sheet material may have different rigidities. In this case, one of the first sheet material and the second sheet material having a higher rigidity can be tensioned against the other. This allows the first fixed linear transmission member and the second fixed linear transmission member to be held in a state of being aligned between the first sheet material and the second sheet material.

[0015] (4) In the wiring member according to any one of (1) to (3), the fixed linear transmission member may be thicker than the free linear transmission member. This makes it easier to regulate the path of the thin free linear transmission member by the relatively thick fixed linear transmission member.

[0016] (5) In the wiring member according to any one of (1) to (4), the fixed linear transmission member may be in contact with the second sheet material, which makes it easier to regulate the path of the detached linear transmission member along the fixed linear transmission member.

[0017] (6) In the wiring member according to any one of (1) to (5), the surface material of the fixed linear transmission member may have a peel strength due to fusion to the first sheet material that is greater than or equal to the peel strength of the free linear transmission member due to fusion to the first sheet material, thereby enabling the fixed linear transmission member to be firmly fused to the first sheet material.

[0018] [Details of the embodiment of the present disclosure] Specific examples of wiring members according to the present disclosure will be described below with reference to the drawings. Note that the present disclosure is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope of the claims.

[0019] [Embodiment] The wiring member according to the embodiment will be described below. Fig. 1 is a plan view showing a wiring member 10. Fig. 2 is a cross-sectional view taken along line II-II in Fig. 1.

[0020] The wiring member 10 includes a first sheet material 12, a second sheet material 14, a fixed linear transmission member 20, and a free linear transmission member 30.

[0021] The first sheet material 12 may be formed in a shape that follows the wiring paths of the fixed linear transmission member 20 and the free linear transmission member 30. Here, the first sheet material 12 is formed in a rectangular shape that is long in one direction. The first sheet material may be curved. The first sheet material may have a curved portion. The first sheet material may have a branched portion.

[0022] The material constituting the first sheet material 12 is not particularly limited, but the first sheet material 12 may be formed of a material containing a resin such as PVC (polyvinyl chloride), PET (polyethylene terephthalate), or PP (polypropylene). The first sheet material 12 may be a sheet material with a uniformly filled interior, or may be a nonwoven sheet, etc. The first sheet material 12 may contain a material such as metal. The first sheet material 12 may have flexibility to be easily bent in the thickness direction. The first sheet material 12 may be a single layer, or may be a multi-layer laminate. When a multi-layer laminate is used, for example, the first sheet material 12 may be a laminate of a resin layer and a resin layer. More specifically, for example, the first sheet material 12 may be a laminate of a resin sheet material with a uniformly filled interior and a nonwoven sheet. For example, the resin sheet material with a uniformly filled interior may be a sheet material to which the fixed linear transmission member 20 can be fused. The nonwoven sheet may be a layer bonded to the resin sheet material with the inside of the sheet material being filled uniformly with a part of the resin sheet material melted and filled between the fibers. In this case, the fixed linear transmission member 20 is fixed to the resin sheet material with the inside of the sheet material being filled uniformly. For example, the first sheet material 12 may be a laminate of a resin layer and a metal layer.

[0023] The second sheet material 14 is superimposed on the first sheet material 12. The second sheet material 14 may be made of the same material as the first sheet material 12.

[0024] The second sheet material 14 is fixed to the first sheet material 12 by a first fixing portion 16 and a second fixing portion 17 spaced apart from the first fixing portion 16. In this embodiment, the first sheet material 12 and the second sheet material 14 have the same rectangular shape. The first fixing portion 16 is a portion where one side of the first sheet material 12 and one side of the second sheet material 14 are fixed in a state where they are overlapped. The second fixing portion 17 is a portion where the other side of the first sheet material 12 and the other side of the second sheet material 14 are fixed in a state where they are overlapped. The first sheet material 12 and the second sheet material 14 may be fixed by welding, such as ultrasonic welding or heat welding. The first sheet material 12 and the second sheet material 14 may also be fixed by an adhesive, a bonding agent, or the like. The first fixing portion 16 and the second fixing portion 17 may be a portion where the first sheet material 12 and the second sheet material 14 are fixed continuously or intermittently.

[0025] In this embodiment, the first sheet material 12 and the second sheet material 14 have the same rectangular shape, and both side portions thereof are continuously fixed to each other. The first sheet material 12 and the second sheet material 14 are not fixed between the first fixing portion 16 and the second fixing portion 17. Therefore, a space in which the fixed linear transmission member 20 and the free linear transmission member 30 can be arranged can be formed between the first sheet material 12 and the second sheet material 14, and between the first fixing portion 16 and the second fixing portion 17.

[0026] It is not essential that the first sheet material 12 and the second sheet material 14 have the same shape. For example, the second sheet material 14, which is smaller than the first sheet material 12, may be fixed to the first sheet material 12 by a first fixing portion and a second fixing portion that are spaced apart from each other in a state where the second sheet material 14 is overlapped with a partial region of the first sheet material 12.

[0027] The first sheet material 12 and the second sheet material 14 may have the same rigidity or different rigidities. The difference in rigidity can be provided by the difference in the material constituting the sheet material (for example, hard PVC or soft PVC), the difference in thickness, etc. The first sheet material 12 and the second sheet material 14 may have different rigidities. For example, the second sheet material 14 may have a rigidity that allows it to confidently maintain a state in which it spreads out in a plane, and the first sheet material 12 may have a flexibility that allows it to be easily bent. In this case, when the second sheet material 14 is fixed to the first sheet material 12 by a first fixing portion 16 and a second fixing portion 17 described later, the first sheet material 12 can be kept in a taut state between the first fixing portion 16 and the second fixing portion 17.

[0028] The fixed linear transmission member 20 and the free linear transmission member 30 are members located between the first sheet material 12 and the second sheet material 14.

[0029] Here, the linear transmission members constituting the fixed linear transmission member 20 and the free linear transmission member 30 are linear members that transmit electricity or light. The linear transmission member includes a transmission line body 22 and a coating layer 24. For example, the linear transmission member may be a general electric wire having a core wire as the transmission line body 22 and a coating layer 24 around the core wire, or may be a shielded wire, a twisted wire, an enamel wire, a nichrome wire, an optical fiber, or the like.

[0030] The linear transmission member for transmitting electricity may be any of various signal lines and various power lines. A part of the linear transmission member for transmitting electricity may be used as an antenna, a coil, or the like for sending a signal or power to or receiving it from space.

[0031] Furthermore, the linear transmission member may be a single linear object, or a composite of multiple linear objects (such as a twisted wire or a cable made up of multiple linear objects assembled together and covered with a sheath).

[0032] In this embodiment, an example is shown in which two fixed linear transmission members 20 and three free linear transmission members 30 are arranged in parallel between the first sheet material 12 and the second sheet material 14. Note that the fixed linear transmission members 20 and the free linear transmission members 30 may be bent or branched in portions other than where they are arranged in parallel.

[0033] The fixed linear transmission member 20 includes a first fixed linear transmission member 20A and a second fixed linear transmission member 20B. In the following description, the fixed linear transmission member 20 may be distinguished into the first fixed linear transmission member 20A and the second fixed linear transmission member 20B as necessary. The first fixed linear transmission member 20A and the second fixed linear transmission member 20B are fixed to the first sheet material 12 between the first fixed portion 16 and the second fixed portion 17 in a parallel state separated from each other.

[0034] The configuration for fixing the fixed linear transmission member 20 to the first sheet material 12 is arbitrary. The fixing manner for fixing the fixed linear transmission member 20 to the first sheet material 12 may be fixing at a contact portion, fixing at a non-contact portion, or a combination of both. Here, fixing at a contact portion means that the contact portion of the fixed linear transmission member 20 and the first sheet material 12 are fixed by adhering to each other. Fixing at a non-contact portion means a fixing manner other than fixing at a contact portion, and for example, sewing thread, adhesive tape, or the like is used to maintain the fixed linear transmission member 20 pressed toward the first sheet material 12.

[0035] The manner of fixing the contact parts may be indirect fixing of the contact parts, direct fixing of the contact parts, or both may be used in different regions. Here, indirect fixing of the contact parts refers to the fixed linear transmission member 20 and the first sheet material 12 being indirectly attached and fixed via an adhesive, pressure sensitive adhesive, double-sided adhesive tape, or the like provided between them. Direct fixing of the contact parts refers to the fixed linear transmission member 20 and the first sheet material 12 being directly attached and fixed without the use of a separate adhesive or the like. In direct fixing of the contact parts, for example, it is considered that the fixed linear transmission member 20 and the first sheet material 12 are attached and fixed by melting a resin contained in at least one of them.

[0036] When the state of directly fixing the contact parts is formed, the resin may be melted by, for example, heat or a solvent. That is, the state of directly fixing the contact parts may be a state of directly fixing the contact parts by heat or a state of directly fixing the contact parts by a solvent. Preferably, the state of directly fixing the contact parts by heat is used.

[0037] At this time, the means for forming the state of direct fixation of the contact parts is not particularly limited, and known means such as welding, fusion, and welding can be used. For example, when forming the state of direct fixation of the contact parts by heat through welding, various welding means such as ultrasonic welding, heat and pressure welding, hot air welding, and high frequency welding can be used. Furthermore, when the state of direct fixation of the contact parts is formed by these means, the fixed linear transmission member 20 and the first sheet material 12 are in a state of direct fixation of the contact parts by that means. Specifically, for example, when the state of direct fixation of the contact parts is formed by ultrasonic welding, the fixed linear transmission member 20 and the first sheet material 12 are in a state of direct fixation of the contact parts by ultrasonic welding.

[0038] The following description is based on the assumption that the fixed linear transmission member 20 and the first sheet material 12 are fixed by ultrasonic welding. The ultrasonic welded portions may be continuous or discontinuous along the longitudinal direction of the fixed linear transmission member 20. FIG. 1 shows an example in which the ultrasonic welded portions 40P are provided discontinuously along the longitudinal direction of the fixed linear transmission member 20.

[0039] The detached linear transmission member 30 is disposed between the first sheet material 12 and the second sheet material 14 in a state in which it is arranged in parallel to the fixed linear transmission member 20. The detached linear transmission member 30 is not fixed to the first sheet material 12. The detached linear transmission member 30 is also not fixed to the second sheet material 14. The detached linear transmission member 30 is disposed along the fixed linear transmission member 20 in a state in which movement in the thickness direction of the main wiring member 10 between the first sheet material 12 and the second sheet material 14 is restricted, and therefore the path of the detached linear transmission member 30 is restricted to follow the fixed linear transmission member 20.

[0040] In this embodiment, the detached linear transmission member 30 includes an intermediate detached linear transmission member 30A disposed between the first fixed linear transmission member 20A and the second fixed linear transmission member 20B. Here, all of the multiple (three) detached linear transmission members 30 are intermediate detached linear transmission members 30A. Since the intermediate detached linear transmission member 30A is disposed between the first fixed linear transmission member 20A and the second fixed linear transmission member 20B, the intermediate detached linear transmission member 30A is less likely to protrude outside the first fixed linear transmission member 20A and the second fixed linear transmission member 20B. Therefore, it is easier to more reliably maintain the intermediate detached linear transmission member 30A along a predetermined path.

[0041] In addition, it is not necessary that the multiple free linear transmission members 30 are arranged in parallel without crossing each other between the first fixed linear transmission member 20A and the second fixed linear transmission member 20B. The multiple free linear transmission members 30 may extend in the space between the first fixed linear transmission member 20A and the second fixed linear transmission member 20B while overlapping or crossing each other.

[0042] The fixed linear transmission member 20 may be thicker than the detached linear transmission member 30. If the fixed linear transmission member 20 is thicker, it can protrude more from the first sheet material 12, and the gap between the fixed linear transmission member 20 and the second sheet material 14 can be reduced. This allows the fixed linear transmission member 20 to more reliably regulate the path of the detached linear transmission member 30.

[0043] In addition, it may be easier to fix the relatively thick fixed linear transmission member 20 to the first sheet material 12 than the relatively thin detached linear transmission member 30 .

[0044] In addition, the fixed linear transmission member 20 may be in a state of contact with the second sheet material 14. This makes it difficult for the detached linear transmission member 30 to move between the fixed linear transmission member 20 and the second sheet material 14, and the path of the detached linear transmission member 30 is more likely to be kept constant.

[0045] Furthermore, since the fixed linear transmission member 20 is fixed to the first sheet material 12 and the free linear transmission member 30 is not fixed to the first sheet material 12, this may be applied in cases where the free linear transmission member 30 is difficult to fix to the first sheet material 12, for example, difficult to fuse, compared to the fixed linear transmission member 20.

[0046] For example, the surface material of the electric wire which is the fixed linear transmission member 20 and the surface material of the free linear transmission member 30 have the following property in relation to the surface material of the first sheet material 12 which is the fixed surface. This property is a case where the peel strength of the fixed linear transmission member 20 fused to the first sheet material 12 is greater than the peel strength of the free linear transmission member 30 fused to the first sheet material 12. The peel strength may be evaluated as follows. For example, the fixed linear transmission member 20 and the free linear transmission member 30 are fused to the first sheet material 12 under the same conditions. For example, the fixed linear transmission member 20 and the free linear transmission member 30 are ultrasonically fused to the first sheet material 12 under the same pressure, pressure time, and vibration conditions. Then, the same type of peel test (for example, a test conforming to any test specified in JIS K6854) is performed on the fixed linear transmission member 20 and the free linear transmission member 30 fused to the first sheet material 12 to evaluate the peel strength. For example, a 180° peel test is performed in which the fixed linear transmission member 20 or the free linear transmission member 30 is folded 180° and pulled against the first sheet material 12, or a T-peel test is performed in which the first sheet material 12 and the fixed linear transmission member 20 or the free linear transmission member 30 are pulled in opposite perpendicular directions against the fused surface. By performing the same type of test on the fixed linear transmission member 20 and the free linear transmission member 30, the magnitude of the peel strength is evaluated.

[0047] Such a difference in peel strength can be brought about by a combination of the constituent material of the fixed surface of the first sheet material 12 and the surface materials of the fixed linear transmission member 20 and the free linear transmission member 30. For example, when the fixed surface of the first sheet material 12 is formed of a material containing PVC, the coating of the fixed linear transmission member 20 may be formed of a material containing PVC, and the coating of the free linear transmission member 30 may be formed of a resin that does not contain PVC, for example, an olefin resin such as PP (polypropylene), PET (polyethylene terephthalate), fluororesin, etc.

[0048] An example of a method for producing the wiring member 10 will now be described.

[0049] As shown in FIG. 3, the fixed linear transmission member 20 is placed on the fixing target surface of the first sheet material 12. Here, the first fixed linear transmission member 20A and the second fixed linear transmission member 20B are placed in parallel with a gap between them. In this state, the first sheet material 12 and the fixed linear transmission member 20 are sandwiched between an ultrasonic welding horn 100 and an anvil 102, and ultrasonic vibration energy is applied. This melts the resin on at least one of the surface of the coating of the fixed linear transmission member 20 and the surface of the fixing target surface of the first sheet material 12. Then, the fixed linear transmission member 20 is fixed to the first sheet material 12 by the ultrasonic welding point 40P.

[0050] Next, as shown in Fig. 4, a detached linear transmission member 30 is placed on the fixing target surface of the first sheet material 12. Since the fixed linear transmission member 20 is fixed to the first sheet material 12, the path of the detached linear transmission member 30 is restricted by the fixed linear transmission member 20 on at least one side on the first sheet material 12. Here, the detached linear transmission member 30 is placed between the first fixed linear transmission member 20A and the second fixed linear transmission member 20B, and therefore, the path of the detached linear transmission member 30 is restricted between the first fixed linear transmission member 20A and the second fixed linear transmission member 20B.

[0051] Then, as shown in FIG. 5, the second sheet material 14 is superimposed on the first sheet material 12. In this state, the ultrasonic welding horn 100 and the anvil 102 sandwich each side of the first sheet material 12 and each side of the second sheet material 14. At this time, the fixed linear transmission member 20 is fixed inside the fixing portion by the ultrasonic welding horn 100 and the anvil 102, and the free linear transmission member 30 is positioned so as to be disposed inside the fixed linear transmission member 20. Therefore, the fixed linear transmission member 20 and the free linear transmission member 30 are unlikely to be sandwiched between the ultrasonic welding horn 100 and the anvil 102. Then, ultrasonic vibration energy is applied to the overlapping portion of the first sheet material 12 and the second sheet material 14. As a result, each side of the first sheet material 12 and each side of the second sheet material 14 are ultrasonically welded.

[0052] According to the wiring member 10 configured in this manner, the detached linear transmission member 30 is arranged in parallel to the fixed linear transmission member 20, and is thereby arranged between the first sheet material 12 and the second sheet material 14 in a state in which the path is regulated by the fixed linear transmission member 20. Therefore, even if the detached linear transmission member 30 is not fixed to the first sheet material 12, the path is regulated between the first sheet material 12 and the second sheet material 14. This makes it possible to easily manufacture a wiring member that keeps multiple linear transmission members, including the fixed linear transmission member 20 and the detached linear transmission member 30, flat.

[0053] By disposing the intermediate free linear transmission member 30A between the first fixed linear transmission member 20A and the second fixed linear transmission member 20B, the intermediate free linear transmission member can be contained between them, thereby more reliably regulating the path.

[0054] Furthermore, if the first sheet material 12 and the second sheet material 14 have different rigidities, the first sheet material 12 or the second sheet material 14 can be tensioned relative to the one having the higher rigidity. This makes it easier to maintain the fixed linear transmission member 20 and the free linear transmission member 30 in a state of being aligned between the first sheet material 12 and the second sheet material 14.

[0055] Furthermore, if the fixed linear transmission member 20 is in contact with the second sheet material 14, it is easy to regulate the path of the detached linear transmission member 30 along the fixed linear transmission member 20. As described above, if one of the first sheet material 12 and the second sheet material 14, whichever has the greater rigidity, is in a taut state relative to the other, it is easy to keep the fixed linear transmission member 20 in contact with the second sheet material 14.

[0056] Furthermore, if the fixed linear transmission member 20 is thicker than the free linear transmission member 30, the fixed linear transmission member 20 can easily regulate the path of the free linear transmission member 30.

[0057] Here, for example, a case may be considered in which the wiring member 10 includes different types of electric wires. The types of electric wires can be distinguished by differences in covering materials, thickness, etc. Different types of electric wires have different conditions for fixing to the first sheet material 12 and ease of fixing. For example, different thicknesses of electric wires require different time and pressure when performing ultrasonic welding. Also, when the covering of the electric wires is different between PVC and olefin-based, it is possible to change the welding conditions. In this way, different types of electric wires have different welding conditions, making it difficult to perform welding work at the same time. If welding work is performed for each type of electric wire, the number of welding operations increases, making the manufacture of the wiring member 10 more tedious.

[0058] Therefore, as in the present wiring member 10, some of the fixed linear transmission members 20 are fixed to the first sheet material 12, and some of the free linear transmission members 30 have their paths regulated by the fixed linear transmission members 20 and are not fixed to the first sheet material 12, thereby reducing the number of fusions and making it easier to manufacture the wiring member 10.

[0059] It is preferable that the fixed linear transmission member 20 can be fixed more firmly or more easily to the first sheet material 12 than the free linear transmission member 30. From this viewpoint, it is preferable that the surface material of the fixed linear transmission member 20 has a property such that the peel strength due to fusion to the first sheet material 12 is greater than or equal to the peel strength of the free linear transmission member 30 due to fusion to the first sheet material 12. This allows the fixed linear transmission member 20 to be firmly fused to the first sheet material 12. In addition, the path of the free linear transmission member 30 can be regulated by the firmly fixed fixed linear transmission member 20.

[0060] <Modification> In the present embodiment, an example has been described in which two fixed linear transmission members 20 are fixed to the first sheet material 12. However, the number of fixed linear transmission members fixed to the first sheet material 12 may be one, or three or more.

[0061] In the above embodiment, an example was shown in which all the free linear transmission members 30 are disposed between the first fixed linear transmission member 20A and the second fixed linear transmission member 20B. However, it is not essential that the free linear transmission members 30 are disposed between the first fixed linear transmission member 20A and the second fixed linear transmission member 20B. For example, as shown in FIG. 6, the free linear transmission members 30 may include an outer free linear transmission member 30B disposed on the outside, not between the first fixed linear transmission member 20A and the second fixed linear transmission member 20B.

[0062] In addition, in the above embodiment, an example has been shown in which the free linear transmission member 30 is thinner than the fixed linear transmission member 20, but it is not essential that the free linear transmission member 30 is thinner than the fixed linear transmission member 20. As shown in Fig. 7, the free linear transmission member 130 corresponding to the free linear transmission member 30 may have the same thickness as the first fixed linear transmission member 20A and the second fixed linear transmission member 20B.

[0063] The configurations described in the above embodiment and modifications can be combined as appropriate as long as they are not mutually inconsistent. [Explanation of symbols]
