In FIG. 3, the III-III cross-section of FIG. 1 is shown. In FIG. 8, the VIII-VIII cross-section of FIG. 7 is shown.

[0012] As shown in FIGS. 1 and 2, the protective material 1 for a wire harness of this embodiment is a member that is attached to the wire harness WH to protect the wire harness WH. The protective material 1 for a wire harness has a protective body 2 and a fixing portion 3. The protective body 2 is wound around the outside of the wire harness WH to protect the wire harness WH. The fixing portion 3 fixes the two end portions 2a, 2a of the protective body 2 to each other.

[0013] As shown in FIG. 3, the protective body 2 is formed by a plurality of sheet materials 10 overlapping each other. The fixing portion 3 fixes the plurality of sheet materials 10 to each other along the stacking direction Ly in which the sheet materials 10 are stacked. The fixing portion 3 is formed by welding, for example. However, the fixing portion 3 may be a member attached to the protective body 2, and may be a clip or a binding member, for example.

[0014] In the protective material 1 for a wire harness according to the present embodiment, the rigidity and flexibility of the protective body 2 can be adjusted according to the number of sheet materials 10 to be stacked. In other words, the protective body 2 with different protective performances according to the number of sheet materials 10 used can be configured. In the protective material 1 for a wire harness according to the present embodiment, it is not necessary to keep in stock a plurality of types of protective materials with different shapes, so that the simplification of inventory management is realized.

[0015] As shown in FIG. 4, the shape of the sheet material 10 in the present embodiment is rectangular. The sheet material 10 is molded from a flexible insulating synthetic resin. The material of the sheet material 10 is, for example, soft polyvinyl chloride (PVC). The illustrated sheet material 10 has a flat plate shape. The thickness t [mm] of the sheet material 10 is determined so that the sheet material 10 has appropriate flexibility and appropriate strength.

[0016] As shown in FIG. 5, the protective body 2 is formed by a plurality of sheet materials 10 overlapping each other. The plurality of sheet materials 10 constituting the protective body 2 have the same material and the same shape. That is, the material and shape of one sheet material 10 constituting the protective body 2 are the same as the material and shape of the other sheet materials 10 constituting the protective body 2. All the sheet materials 10 have the same dimensions. For example, when the shape of the sheet material 10 is rectangular, the lengths and thickness t of the corresponding sides 11, 12 in the plurality of sheet materials 10 are the same.

[0017] As shown in FIG. 5, a plurality of sheet materials 10 overlap such that one sheet material 10 covers the entire other sheet material 10. The illustrated rectangular sheet material 10 has a pair of first sides 11 and a pair of second sides 12. The first side 11 of one sheet material 10 is overlapped with the other first side 11, and the second side 12 of one sheet material 10 is overlapped with the other second side 12.

[0018] As shown in FIG. 6, the protective body 2 is wound around the wire harness WH. The wire harness WH includes at least one electric wire W. The illustrated wire harness WH includes a plurality of electric wires W. The protective body 2 is wound around the wire harness WH so as to wrap the wire harness WH. Note that the protective body 2 may be held by a jig or the like so as to have a substantially U shape or V shape in advance. In this case, the wire harness WH is placed on the held protective body 2.

[0019] The protective body 2 wound around the wire harness WH has an inner surface 2b. The inner surface 2b is a surface facing the wire harness WH and forms a space portion for accommodating the wire harness WH. The protective body 2 is wound around the wire harness WH with the inner surfaces 2b of the two end portions 2a facing each other.

[0020] The fixing portion 3 for fixing both end portions 2a to each other is formed by, for example, a welding machine 100. The welding means by the welding machine 100 may be ultrasonic welding, thermal welding, laser welding, or other means. The welding machine 100 sandwiches, for example, the two end portions 2a and melts the plurality of sheet materials 10 by heat generated by ultrasonic waves or the like to form the fixing portion 3.

[0021] As shown in FIG. 3, a part of the sheet material 10 is melted to form the fixing portion 3. The fixing portion 3 extends along the stacking direction Ly from one end portion 2a to the other end portion 2a. In other words, the fixing portion 3 penetrates the plurality of sheet materials 10 along the stacking direction Ly. By forming the fixing portion 3, the opening between the two end portions 2a is closed. As shown in FIG. 3, a plurality of sheet materials 10 are fixed at the same position in the opening of the protective body 2.

[0022] Note that when the protective body 2 is wound around the wire harness WH, the position of the end face 2c of the sheet material 10 may shift. This shift is caused by, for example, the difference between the inner and outer circumferences of the portion wound around the wire harness WH. The end face 2c of the sheet material 10 that is relatively on the inner side protrudes with respect to the end face 2c of the sheet material 10 that is relatively on the outer side.

[0023] Even when such a shift occurs, one sheet material 10 overlaps so as to cover the entire other sheet material 10. For example, the protective body 2 in FIG. 3 has three sheet materials 10A, 10B, and 10C. The sheet material 10A is located on the outermost side, and the sheet material 10C is located on the innermost side. The sheet material 10B overlaps the sheet material 10A so as to cover the entire sheet material 10A. The sheet material 10C overlaps the sheet material 10B so as to cover the entire sheet material 10B.

[0024] The protective material 1 for a wire harness may have a plurality of fixing portions 3 as shown in FIG. 2. The plurality of fixing portions 3 shown in FIG. 2 are arranged at intervals along the axial direction X of the wire harness WH. The plurality of fixing portions 3 may be arranged at equal intervals. In the portion between the two fixing portions 3, the plurality of sheet materials 10 can slide or the plurality of sheet materials 10 can be separated. Therefore, the protective material 1 for a wire harness having a plurality of fixing portions 3 can be bent flexibly. That is, the protective material 1 for a wire harness having a plurality of fixing portions 3 has high followability with respect to the wire harness WH routed while being bent.

[0025] Note that the sheet material 10 may have concave or convex portions. FIGS. 7 and 8 show a sheet material 10 having a curved portion 13 curved in a spherical shape. The sheet material 10 in FIG. 7 has a plurality of curved portions 13. As shown in FIG. 8, the curved portion 13 is curved toward one side in the thickness direction Z of the sheet material 10. One surface of the curved portion 13 is a convex surface, and the other surface of the curved portion 13 is a concave surface.

[0026] The rigidity and flexibility of the sheet material 10 can be adjusted by the arrangement of the curved portions 13. In the sheet material 10 shown in FIG. 9, a plurality of curved portions 13 are arranged in a lattice pattern. That is, the plurality of curved portions 13 are arranged along a first direction D1 and a second direction D2. The first direction D1 is a direction along the first side 11, and the second direction D2 is a direction along the second side 12. The first direction D1 and the second direction D2 are orthogonal to each other.

[0027] When a plurality of curved portions 13 are arranged in a lattice pattern, a region 18 having high flexibility is formed between adjacent curved portions 13. Such a sheet material 10 has high flexibility when wound around the wire harness WH.

[0028] In the sheet material 10 shown in FIG. 10, a plurality of curved portions 13 are arranged alternately in a staggered pattern. The plurality of curved portions 13 have a first row R1 and a second row R2. The first row R1 and the second row R2 have a plurality of curved portions 13 arranged in the first direction D1. The first row R1 and the second row R2 are arranged shifted in the first direction D1. For example, in the first direction D1, the curved portion 13 of the second row R2 is arranged between two curved portions 13 of the first row R1.

[0029] The sheet material 10 in Fig. 10 is wound around the wire harness WH with the portion along the first side 11 as the end 2a, for example. The sheet material 10 with a plurality of alternately arranged curved portions 13 has high rigidity when wound around the wire harness WH. Such a sheet material 10 can improve the rigidity of the wire harness protective material 1 against bending. Note that the sheet material 10 may have other columns in addition to the first column R1 and the second column R2. In other words, the sheet material 10 may have curved portions 13 arranged in three or more columns.

[0030] The sheet materials 10 having the curved portions 13 may be stacked so that the curved portions 13 fit together. That is, a plurality of sheet materials 10 may be stacked such that the curved portion 13 of one sheet material 10 enters the curved portion 13 of another sheet material 10. Differently, a plurality of sheet materials 10 may be stacked so that the positions of the curved portions 13 are displaced. In this case, a gap is formed between the two sheet materials 10, and the rigidity and impact resistance of the wire harness protective material 1 are improved.

[0031] The protector 2 may be wound around the wire harness WH with the convex surface of the curved portion 13 facing outward. In this case, the contact between the peripheral components and the wire harness protective material 1 becomes point contact, and the wear resistance of the wire harness protective material 1 is improved. Also, the generation of abnormal noise is suppressed because the contact area with the peripheral components is small.

[0032] The shape of the curved portion provided on the sheet material 10 is not limited to a spherical shape. Fig. 11 shows a sheet material 10 having a groove-shaped curved portion 14. The sheet material 10 has a plurality of curved portions 14. The curved portion 14 extends linearly and has an arcuate cross-sectional shape. The curved portion 14 in Fig. 11 extends in the second direction D2. A predetermined interval is provided between two adjacent curved portions 14. The plurality of curved portions 14 are arranged at equal intervals along the first direction D1, for example.

[0033] The sheet material 10 is wound around the wire harness WH, for example, with the portion along the second side 12 as the end portion 2a. In this case, the sheet material 10 can improve the rigidity of the protective material 1 for the wire harness against bending. Differently, the sheet material 10 may be wound around the wire harness WH with the portion along the first side 11 as the end portion 2a. In this case, the sheet material 10 can bend flexibly following the wire harness WH.

[0034] The sheet material 10 having the curved portions 14 is, for example, overlapped so that the curved portions 14 fit together. That is, in the protective body 2, a plurality of sheet materials 10 may be overlapped such that the curved portion 14 of one sheet material 10 enters the curved portion 14 of the other sheet material 10. Differently, a plurality of sheet materials 10 may be overlapped such that the positions of the curved portions 14 are displaced. Note that a plurality of sheet materials 10 may be overlapped such that the curved portions 14 protrude in opposite directions from each other. In this case, a gap is formed between the two sheet materials 10 at the portion where the convex surfaces of the curved portions 14 contact each other.

[0035] The protective material 1 for the wire harness may have a linear fixing portion 3. FIG. 12 shows the protective material 1 for the wire harness having the linear fixing portion 3. The fixing portion 3 extends linearly along the axial direction X. The fixing portion 3 is provided, for example, from one end to the other end of the axial direction X at the end portion 2a. The linear fixing portion 3 can improve the rigidity of the end portion 2a and the straightness of the wire harness WH.

[0036] As the fixing part 3, the bundling member 30 shown in FIG. 13 may be used. The bundling member 30 is a member called a bundling band, for example, and has a head part 31 and a band part 32. The band part 32 is inserted into a through hole 2d provided at an end 2a of the protective body 2 and engages with the head part 31. The bundling member 30 fixes a plurality of sheet materials 10 to each other along the stacking direction Ly. The through hole 2d is formed in each sheet material 10 constituting the protective body 2. The plurality of sheet materials 10 are stacked so that the through holes 2d face each other. The illustrated protective body 2 has a plurality of through holes 2d. The plurality of through holes 2d are arranged at intervals along the axial direction X.

[0037] As the fixing part 3, the clip 40 shown in FIGS. 14 and 15 may be used. The clip 40 is a fastening member called a two-piece clip or a push rivet. The clip 40 shown in FIGS. 14 and 15 has a head part 41, a pin 42, and a plurality of leg parts 43. The pin 42 penetrates the head part 41. The pin 42 and the leg parts 43 are inserted into through holes of the protective body 2. The clip 40 is configured such that when the pin 42 is pushed in, the leg parts 43 spread. The clip 40 sandwiches a plurality of sheet materials 10 between the spread leg parts 43 and the head part 41 and fastens two ends 2a of the protective body 2. The clip 40 fixes a plurality of sheet materials 10 to each other along the stacking direction Ly.

[0038] In addition, when forming the linear fixing part 3 as shown in FIG. 12, for example, a linear clip such as a clip called a hood clip or a sealing clip may be used. FIG. 16 shows a side view of the protective body 2 fastened by the linear clip 50. The clip 50 has two holding bodies 51 and an engaging structure 52. The clip 50 is molded of, for example, an insulating synthetic resin.

[0039] The holding members 51 sandwich and hold the two end portions 2a of the protective body 2. The two holding members 51 are formed in a plate shape or a rod shape, and face each other in the stacking direction Ly with the two end portions 2a therebetween. The engaging structure 52 engages the two holding members 51. The engaging structure 52 is constituted by, for example, an engaging arm 52a of one holding member 51 and a locking portion 52b of the other holding member 51. In this case, the locking portion 52b locks the engaging arm 52a in the stacking direction Ly. The engaging structure 52 is disposed at both ends of the holding member 51 in the axial direction X. The clip 50 can fix a plurality of sheet materials 10 to each other along the stacking direction Ly. In addition to both ends of the holding member 51, an additional engaging structure may be provided at the intermediate portion of the holding member 51.

[0040] Next, another configuration example of the sheet material 10 will be described. The sheet material 10 shown in FIG. 17 has a base material layer 15 and an adhesive layer 16. The base material layer 15 is the main body of the sheet material 10 and is formed of, for example, soft polyvinyl chloride (PVC). The adhesive layer 16 is formed by, for example, applying an adhesive to the base material layer 15. The adhesive layer 16 may be an adhesive sheet or an adhesive tape attached to the base material layer 15.

[0041] The sheet material 10 is adhered to another sheet material 10 by the adhesive layer 16. A plurality of sheet materials 10 are stacked as shown in FIG. 18, for example. In the protective body 2 of FIG. 18, in all the sheet materials 10, the adhesive layer 16 is located on the same side with respect to the base material layer 15. The protective body 2 shown in FIG. 18 is wound around the wire harness WH so that the adhesive layer 16 exposed on the surface faces the wire harness WH, for example.

[0042] In this case, as shown in FIG. 19, the adhesive layer 16 can adhere to the wire harness WH and restrain the wire harness WH. As a result, the wire harness protective material 1 can improve the straightness of the wire harness WH. Further, since the plurality of sheet materials 10 are adhered to each other, the wire harness protective material 1 can improve the straightness of the wire harness WH.

[0043] With respect to the protective body 2 wound around the wire harness WH, the end portions 2a are fixed to each other by the fixing portion 3. The fixing portion 3 may be formed by welding or may be a member such as a bundling member or a clip. When the fixing portion 3 is a bundling member or a clip, through holes 2d are provided in the base material layer 15 and the adhesive layer 16.

[0044] A plurality of fixing portions 3 may be arranged along the axial direction X with respect to the protective body 2 having the adhesive layer 16, or a linear fixing portion 3 may be arranged along the axial direction X with respect to the protective body 2. In addition to the fixing portion 3, the two end portions 2a are fixed to each other by the adhesive layer 16. Therefore, the fixing strength at the opening is improved.

[0045] Note that the plurality of sheet materials 10 may be stacked so that the base material layer 15 faces the wire harness WH. In this case, as shown in FIG. 20, the sheet material 10 arranged at the end portion in the stacking direction Ly has the adhesive layer 16 facing the adhesive layer 16 of the other sheet material 10. That is, the adhesive layers 16 of the two sheet materials 10 are adhered to each other. Such a protective body 2 is wound around the wire harness WH with the base material layer 15 facing the wire harness WH. In this case, since the protective material 1 for the wire harness hardly restrains the movement of the wire harness WH, the flexibility of the wire harness WH can be improved. Note that a sheet material 10 having no adhesive layer 16 may be used as the sheet material 10 arranged at the end portion in the stacking direction Ly.

[0046] The sheet material 10 having the adhesive layer 16 may have a spherical curved portion 13, a groove-shaped curved portion 14, or other shaped curved portions. A plurality of sheet materials 10 having the curved portion 13 may be stacked so that the curved portions 13 fit together, or may be stacked so that the positions of the curved portions 13 are displaced. A plurality of sheet materials 10 having the curved portion 14 may be stacked so that the curved portions 14 fit together, or may be stacked so that the positions of the curved portions 14 are displaced.

[0047] As described above, the protective material 1 for wire harnesses according to the present embodiment includes a protective body 2 and a fixing portion 3. The protective body 2 is formed by a plurality of sheet materials 10 overlapping each other. The fixing portion 3 fixes both end portions 2a of the protective body 2 to each other. The plurality of sheet materials 10 have the same material and the same shape.

[0048] In the protective body 2, the plurality of sheet materials 10 overlap such that one sheet material 10 covers the entire other sheet material 10. The protective body 2 has an inner surface 2b facing the wire harness WH in a state of being wound around the wire harness WH. The protective body 2 is wound around the wire harness WH with the inner surfaces 2b of both end portions 2a of the protective body 2 facing each other. The fixing portion 3 fixes the plurality of sheet materials 10 to each other along the lamination direction Ly in which the plurality of sheet materials 10 are laminated. In the protective material 1 for wire harnesses according to the present embodiment, it is possible to manufacture protective materials with different required protective performances from the same sheet material 10. Therefore, according to the protective material 1 for wire harnesses of the present embodiment, it is possible to reduce the types of parts required for protective materials with different protective performances.

[0049] The sheet material 10 may include a base material layer 15 and an adhesive layer 16, and may be adhered to other sheet materials 10 by the adhesive layer 16. Such a sheet material 10 can improve the rigidity of the protective material 1 for wire harnesses.

[0050] The fixing portion 3 may be formed by welding the plurality of sheet materials 10. In this case, it is possible to automate the process of forming the fixing portion 3 and improve the efficiency.

[0051] In the protective material 1 for wire harnesses, a plurality of fixing portions 3 may be arranged at intervals along the axial direction X of the wire harness WH. In this case, the protective material 1 for wire harnesses can be flexibly bent.

[0052] In addition, when the protective body 2 is constituted by the sheet material 10 that does not have the adhesive layer 16, a configuration for suppressing the displacement of the sheet material 10 may be provided. For example, as shown in FIG. 21, a welding portion 17 for welding a plurality of sheet materials 10 may be formed. The protective body 2 in FIG. 21 has a plurality of welding portions 17. The welding portion 17 is formed so as to penetrate the protective body 2 along the stacking direction Ly.

[0053] The plurality of welding portions 17 are arranged along the axial direction X of the wire harness WH when the wire harness WH is wound around the welding portions 17. In the protective body 2 of FIG. 21, the plurality of welding portions 17 are arranged side by side in the second direction D2. In this case, the protective body 2 is wound around the wire harness WH so that the wire harness WH extends in the second direction D2. By arranging the plurality of welding portions 17 at intervals, the flexibility of the wire harness protective material 1 is improved. The welding portion 17 is arranged, for example, at the central portion of the protective body 2 in the first direction D1.

[0054] As shown in FIG. 22, the welding portion 17 may be formed linearly. The welding portion 17 in FIG. 22 extends along the axial direction X of the wire harness WH when the wire harness WH is wound around the welding portion 17. The linear welding portion 17 can improve the straightness of the wire harness protective material 1.

[0055] When the protective body 2 is constituted by the sheet material 10 that does not have the adhesive layer 16, a jig for suppressing the displacement of the sheet material 10 may be used. For example, a jig having a positioning pin that penetrates the protective body 2 is used. In this case, for example, each sheet material 10 is provided with a through hole corresponding to the positioning pin. The jig supports the protective body 2 and positions the plurality of sheet materials 10 by the positioning pins. The wire harness WH is placed, for example, on the protective body 2 supported by the jig.

[0056] Note that the shape of the sheet material 10 is not limited to the shape exemplified in the embodiment. The shape of the sheet material 10 in plan view may be a polygonal shape such as a hexagon, an oval shape, or other shapes.

[0057] The content disclosed in the above embodiments can be executed by appropriate combination.
