[0024] (Summary of this Embodiment)

[0025] First, a summary of the embodiments disclosed in this specification will be described.

[0026] (1) The wire harness module includes: a wire harness in which at least one electric wire is fixed along a strip-shaped base member; a holding member that holds a sheet-like redundant portion of the base member different from the portion where the electric wire is fixed; and a protective member that is assembled to a slidable slider, the protective member having a housing portion that houses the holding member, and the housing portion having a locking portion that can lock with the holding member in the extending direction of the wire harness.

[0027] In a wire harness module having such a structure, a redundant portion different from the portion where the wire is fixed is held by a holding member, and the holding member holding the redundant portion is housed in a housing portion of a protective member. Further, in the housing portion, the holding member can be locked to a locking portion of the housing portion in the extending direction of the wire harness. Thereby, the wire harness can be fixed in such a manner as not to be displaced relative to the slider. Further, when a load such as pulling the wire harness is applied to the wire harness, the load is applied to the redundant portion of the wire harness, the holding member, and the locking portion between the holding member and the protective member. That is, it is possible to suppress the load from being applied to the wire, and it is possible to avoid damage to the wire.

[0028] (2) It may also be configured such that the holding member has at least one pair of holding portions that sandwich the redundant portion from both sides, and each of the holding portions has a plurality of protrusions protruding toward the redundant portion.

[0029] According to such a structure, by the plurality of protrusions in the pair of holding portions being inserted into the redundant portion of the base member, it is possible to suppress the wire harness from coming off the protective member. Further, according to such a structure, compared with the case where the redundant portion is held by the holding member so as to penetrate the redundant portion, for example, it is possible to prevent a reduction in the strength of the redundant portion.

[0030] (3) It may also be configured such that the plurality of protrusions in one of the pair of holding portions and the plurality of protrusions in the other of the pair of holding portions are arranged alternately, and the redundant portion is arranged in a meandering manner between the alternately arranged plurality of protrusions.

[0031] According to such a structure, compared with the case where the plurality of protrusions are arranged at the same position with the redundant portion as a boundary between the pair of holding portions, for example, it is possible to increase the degree of insertion of the protrusions into the redundant portion. Thereby, it is possible to improve the holding force of the wire harness in the protective member.

[0032] (4) In the wire harness module according to claim 2 or claim 3, a plurality of the wires are arranged and fixed along the base member, redundant portions are formed on both sides of the portion where the wires are fixed, the protective member has a pair of holding portions that hold each of the redundant portions, and the two pairs of holding portions are connected by a pair of connecting portions, and the pair of connecting portions may be further connected by a hinge.

[0033] According to such a structure, the load applied to the wire harness can be dispersed to both sides of multiple wires in the wire harness. That is to say, compared with the case where the load is applied to one end of the wire harness, the burden applied to the redundant part can be reduced. Thereby, the holding force of the wire harness in the protective member can be improved. In addition, two pairs of clamping portions are connected by a pair of connecting portions, and the pair of connecting portions are further connected by a hinge. That is to say, the holding member can be constituted by a single member, so compared with the case where each clamping portion is constituted separately, for example, an increase in the number of components can be suppressed, and the assembly operation of assembling the holding member to the wire harness can be simplified.

[0034] (5) A wire harness laying device includes the wire harness module and a surplus length storage portion that stores the surplus length of the wire harness of the wire harness module.

[0035] (Details of this embodiment)

[0036] The wire harness module and the wire harness laying device disclosed in this specification are not limited to the following examples, but are shown by the claims, and are intended to include all changes within the meaning equivalent to the claims and the scope.

[0037] <Embodiment>

[0038] Refer to Figures 1 to 11 An embodiment of the technology disclosed in this specification will be described.

[0039] As Figure 1 shown, this embodiment illustrates a wire harness laying device 10 that lays a wire harness 30 between a floor portion (not shown) of a vehicle and a seat S that can be slidably assembled on a pair of guide rails 90.

[0040] (Guide rail 90)

[0041] A pair of guide rails 90 are each made of metal and are formed in a rectangular tube shape that is long in the front-rear direction, as Figure 1 and Figure 2 shown. As the metal constituting the guide rail 90, any metal such as stainless steel, aluminum, aluminum alloy, etc. can be appropriately selected as needed. The pair of guide rails 90 are arranged in parallel at intervals in the left-right direction on the floor.

[0042] In one of the guide rails 90, a seat slider 80 for the seat assembled to the seat S is disposed so as to be movable in the front-rear direction.

[0043] (Slider 80)

[0044] The slider 80 is, for example, made of synthetic resin or metal, and can be at a position behind the rear end of the guide rail 90 where the slider 80 is disposed as Figure 1 shown and a position as Figure 2The slider 80 shown is configured to slide in the front-rear direction between positions in front of the front end of the guide rail 90.

[0045] As Figure 2 shown, an assembly portion 82 is provided on the upper portion of the slider 80, and the assembly portion 82 protrudes upward from the upper portion of the guide rail 90 through a through groove 92 provided in the upper portion of the guide rail 90.

[0046] The assembly portion 82 is fixed by bolts or the like to an unillustrated seat-side assembly portion provided on the seat S. Thus, the seat S can slide in the front-rear direction on the guide rail 90.

[0047] A wire harness module 20 (to be described later) of the wire harness laying device 10 is assembled to the front end portion of the assembly portion 82.

[0048] (Wire harness laying device 10)

[0049] As Figure 2 shown, the wire harness laying device 10 includes a wire harness module 20 that fixes the wire harness 30 to the slider 8, and a wire harness storage portion 11 that stores the excess length of the wire harness 30.

[0050] (Wire harness storage portion 11)

[0051] As Figure 2 shown, the wire harness storage portion 11 is assembled to the front end portion of the guide rail 90. The wire harness storage portion 11 is formed in a box shape that extends along the side portion of the guide rail 90 from the front end portion of the guide rail 90. The interior of the wire harness storage portion 11 communicates with the front end opening of the guide rail 90, and the excess length portion of the wire harness 30 generated by the movement of the slider 80 is stored inside the wire harness storage portion 11.

[0052] (Wire harness module 20)

[0053] As Figure 3 shown, the wire harness module 20 includes: a wire harness 30 having a plurality of electric wires 32; a holding member 40 that holds the wire harness 30; and a protection member 60 that fixes the holding member 40 to the slider 80.

[0054] (Wire harness 30)

[0055] As Figures 3 to 7 shown, the wire harness 30 has: a plurality of electric wires 32 formed by covering core wires with an insulating coating portion; and a pair of base members 34 that sandwich and fix the plurality of electric wires 32 from both sides. The wire harness 30 in the present embodiment is constituted by five electric wires 32 being sandwiched from both sides by a pair of base members 34.

[0056] As Figure 7As shown, a pair of base members 34 are formed in a strip shape that is long in the front-rear direction using a sheet-like non-woven fabric. The non-woven fabric is a fabric formed by winding or bonding fibers, and examples thereof include a fiber sheet, a net (a film-like sheet composed only of fibers), or a batting (a blanket-like fiber). In the present embodiment, the base member 34 is composed of a fiber sheet. Additionally, the base member 34 may also be a spun fabric woven from natural fibers or synthetic fibers.

[0057] At the central portion of the base member 34 in the vertical direction, five electric wires 32 are arranged and fixed flatly in the vertical direction along the base member 34.

[0058] As Figures 3 to 7 shown, in the wire harness 30, the portion where the five electric wires 32 are sandwiched and fixed by the pair of base members 34 is formed as a wire fixing portion 35, and both sides in the vertical direction of the wire fixing portion 35 are formed as redundant portions 36 for fixing the base members 34 to each other.

[0059] The fixing of the electric wire 32 to the base member 34 is fixed by known fixing methods such as joining the electric wire 32 to the base member 34 using ultrasonic welding, hot melting, or fixing the electric wire 32 using an adhesive or bonding agent, or sewing the electric wire 32 to the base member 34. The fixing of the base members 34 to each other in the redundant portion 36 is fixed by known fixing methods such as joining the base members 34 to each other using ultrasonic welding, hot melting, or fixing the base members 34 to each other using an adhesive or bonding agent.

[0060] At both end faces of the base member 34, as Figure 5 and Figure 6 shown, a plurality of electric wires 32 are led out from the pair of base members 34. The electric wires 32 led out from the base member 34 to the seat S side are connected to various electrical components mounted on the seat S, and the electric wires 32 led out to the floor portion side are connected to machines (not shown) mounted on the vehicle.

[0061] (Holding member 40)

[0062] The holding member 40 is formed of a synthetic resin. As Figures 5 to 7 , Figure 10 shown, the holding member 40 is assembled to the rear end portion of the base member 34 in the wire harness 30. The holding member 40 includes: a pair of connecting portions 42 disposed along both sides in the left-right direction of the wire harness 30; a pair of hinges 43 connecting the lower end portions of the pair of connecting portions 42 to each other; and two sets of a pair of clamping portions 50 provided at the upper end portions and the lower end portions of the pair of connecting portions 42.

[0063] (Connecting portion 42)

[0064] As Figures 7 to 10As shown, a pair of connecting portions 42 are each formed in a rectangular flat plate shape. At the lower end portions of the pair of connecting portions 42, a pair of hinges 43 that can elastically deform are formed in the front-rear direction, and the pair of hinges 43 connect the pair of connecting portions 42 to each other.

[0065] In the state before the holding member 40 is assembled to the wire harness 30, as Figures 7 to 9 shown, the pair of hinges 43 extend straight, and the pair of connecting portions 42 are in a state where the inner surface 42A on the wire harness 30 side of each connecting portion 42 faces upward.

[0066] In the state where the protective member 60 is assembled to the wire harness 30, as Figure 5 、 Figure 6 and Figure 10 shown, the pair of hinges 43 elastically deform into a folded state, so that the pair of connecting portions 42 are arranged along both sides in the left-right direction of the wire harness 30.

[0067] As Figure 6 and Figure 7 shown, a plurality of support ribs 44 that contact the wire fixing portion 35 of the wire harness 30 are formed on the inner surface 42A of the pair of connecting portions 42.

[0068] Each support rib 44 is formed in a shape extending in the up-down direction with a triangular cross section and is formed in the front-rear direction in an array.

[0069] As Figure 6 shown, the plurality of support ribs 44 in the pair of connecting portions 42 are arranged offset in the front-rear direction with the wire harness 30 as a boundary. Therefore, when the pair of connecting portions 42 are arranged on both sides in the left-right direction of the wire harness 30, the support ribs 44 of each connecting portion 42 contact the wire fixing portion 35 of the wire harness 30 in a staggered arrangement in the front-rear direction. Thus, the wire fixing portion 35 can be supported from both sides in the left-right direction in the pair of connecting portions 42.

[0070] (Clamping portion 50)

[0071] As Figure 5 and Figure 7 shown, a pair of clamping portions 50 include a first protruding portion 52 that protrudes from the connecting portion 42 toward the redundant portion 36 side of the wire harness 30, and a plurality of second protruding portions 54 that further protrude from the first protruding portion 52 toward the redundant portion 36 side.

[0072] The first protruding portion 52 is formed over the entire length of the connecting portion 42 in the front-rear direction. The protruding amount of the first protruding portion 52 from the connecting portion 42 is formed to be slightly larger than that of the support rib 44 of the connecting portion 42 protruding toward the redundant portion 36 side.

[0073] The second protruding portions 54 are formed in a row at intervals in the front-rear direction. As Figure 5As shown, a plurality of second protrusions 54 in a pair of clamping portions 50 are arranged in a staggered manner in the front-back and left-right directions with the wire harness 30 as a boundary, similar to the support ribs 44. The protruding amount of the second protrusions 54 protruding from the first protrusions 52 is formed such that the tips of the second protrusions 54 arranged in a staggered manner in the front-back direction are aligned in a straight line in the front-back direction.

[0074] Therefore, when the protective member 60 is assembled to the wire harness 30 and a pair of connecting portions 42 are arranged on both sides in the left-right direction of the wire harness 30, as Figure 5 shown, a plurality of second protrusions 54 in a pair of connecting portions 42 press the redundant portion 36 in a staggered manner in the front-back direction from both sides in the left-right direction. The redundant portion 36 is arranged in a meandering manner in the left-right direction between the pair of clamping portions 50.

[0075] As Figure 10 shown, two misalignment detection protrusions 46 protruding outward are formed on the outer side surface 42B of one of the pair of connecting portions 42. The misalignment detection protrusions 46 are circular in side view and are arranged in a row in the up-down direction.

[0076] On the outer side surface 42B of the connecting portion 42 in the pair of connecting portions 42 where the misalignment detection protrusions 46 are not formed, a plurality of square ribs 45 extending in the up-down direction are formed. Three square ribs 45 are formed in the present embodiment. Two of the three square ribs 45 are formed at the leading edge and the trailing edge of the connecting portion 42, and the remaining one square rib 45 is formed at the center portion in the front-back direction of the connecting portion 42.

[0077] Therefore, the front end surface and the rear end surface of the connecting portion 42 having the square ribs 45 have a larger area than those of the other connecting portion 42.

[0078] (Protective member 60)

[0079] The protective member 60 is formed of synthetic resin. As Figure 10 and Figure 11 shown, the lower member 71 and the upper member 76 of the protective member 60 that can be divided in the up-down direction are assembled into one body by engaging the locking portion 77 formed on the upper member 76 with the locked member 72 formed on the lower member 71.

[0080] As Figure 3 and Figure 4 shown, the protective member 60 extends in the up-down direction and is formed in a square tube shape that extends in an L shape from the lower end portion toward the right front.

[0081] An assembly piece 61 is formed at the rear end portion of the protective member 60. The assembly piece 61 is fastened by the assembly portion 82 of the slider 80 and the fastening member 85 including the bolt 86 and the nut 87. Thus, the protective member 60, and further the wire harness module 20, are fixed to the slider 80

[0082] The wire harness 30 can be inserted through the protective member 60, and a storage portion 62 is provided at the front end portion of the protective member 60, and the holding member 40 can be fitted into the storage portion 62 from above.

[0083] As Figure 5 , Figure 6 and Figure 10 shown, the storage portion 62 is constituted by fitting a storage recess 73 formed in the lower member 71 and a cover portion 78 formed in the upper member 76 in the vertical direction.

[0084] The storage recess 73 includes: a front wall 74 facing the front end face 40F of the holding member 40 in the front-rear direction; a rear wall 75 facing the rear end face 40B of the holding member 40 in the front-rear direction; and a pair of side walls 73W connecting the front wall 74 and the rear wall 75, and the storage recess 73 is formed in a rectangular parallelepiped box shape that opens upward.

[0085] The holding member 40 in the normal arrangement state with the hinge 43 arranged downward can be stored from above in the storage recess 73. Insertion slits 73A for inserting the wire harness 30 are formed in the front wall 74 and the rear wall 75 of the storage recess 73. The insertion slits 73A are formed to extend downward from the upper edges of the front wall 74 and the rear wall 75, and when the holding member 40 is stored in the storage recess 73, the wire harness 30 is inserted from above. The wire harness 30 led out forward from the insertion slit 73A passes through the guide rail 90 and is introduced into the wire harness storage portion 11, and the wire harness 30 led out backward from the insertion slit 73A is restricted from floating by the wire restraint 73B provided in the protective member 60 and led out upward.

[0086] The height dimension and the front-rear, left-right length dimensions in the storage recess 73 are substantially the same as the height dimension and the front-rear, left-right length dimensions of the protective member 60. Here, the so-called substantially the same includes the following cases: the case where the height dimension and the front-rear, left-right length dimensions of the protective member 60 are the same as the height dimension and the front-rear, left-right length dimensions in the storage recess 73; and the case where even if the height dimension and the front-rear, left-right length dimensions of the protective member 60 are not the same as the height dimension and the front-rear, left-right length dimensions in the storage recess 73, they can be regarded as substantially the same.

[0087] Therefore, when the holding member 40 is stored from above in the storage recess 73, as Figure 5 and Figure 6 shown, the front end face 40F of the holding member 40 and the front wall 74 of the storage recess 73 can be locked in the front-rear direction, and the rear end face 40B of the holding member 40 and the rear wall 75 of the storage recess 73 can be locked in the front-rear direction.

[0088] That is, by engaging the front end face 40F of the holding member 40 and the front wall 74 in the front-rear direction, the holding member 40 can be prevented from falling off forward from the protective member 60. In addition, by engaging the rear end face 40B of the holding member 40 and the rear wall 75 in the front-rear direction, the holding member 40 can be prevented from being displaced rearward within the protective member 60. Further, by bringing the pair of connecting portions 42 of the holding member 40 into contact with the pair of side walls 73W of the receiving recess 73 in the left-right direction, the pair of connecting portions 42 are restricted from spreading in the left-right direction within the receiving recess 73.

[0089] As Figure 5 , Figure 6 , Figure 10 and Figure 11 shown, an incorrect fitting detection groove 73W1 extending downward from the upper edge of the side wall 73W is formed in one of the side walls 73W of the receiving recess 73 in the left-right direction. The depth dimension of the incorrect fitting detection groove 73W1 is formed to be of a size capable of completely receiving the two incorrect fitting detection protrusions 46 of the holding member 40.

[0090] When the holding member 40 in the normal configuration state is fitted into the receiving recess 73, the incorrect fitting detection protrusion 46 is fitted into the incorrect fitting detection groove 73W1. That is, the incorrect fitting detection groove 73W1 and the incorrect fitting detection protrusion 46 have the function of preventing incorrect fitting of the holding member 40 in an incorrect configuration state where the front-rear direction is reversed or the up-down direction is reversed with respect to the receiving recess 73.

[0091] On the other hand, as Figure 10 shown, the cover portion 78 of the upper member 76 is formed in a cover shape that opens downward, and the receiving recess 73 can be fitted into the cover portion 78 from below. As Figure 5 and Figure 6 shown, the cover portion 78 has: an outer front wall 79 opposed to the front wall 74 of the receiving recess 73 in the front-rear direction; and a pair of outer side walls 78W disposed along the outer surfaces of the respective side walls 73W of the receiving recess 73. Therefore, when the receiving recess 73 is fitted into the cover portion 78, the outer front wall 79 can engage the front end face 40F of the holding member 40 from the front through the front wall 74 of the receiving recess 73. In addition, the outer side walls 78W restrict the pair of connecting portions 42 from spreading in the left-right direction through the side walls 73W of the receiving recess 73.

[0092] That is, as Figure 5 and Figure 6 shown, the holding member 40 is double-locked from the front by the front wall 74 of the receiving recess 73 and the outer front wall 79 of the cover portion 78 in the receiving portion 62. In addition, the pair of connecting portions 42 are double-restricted from spreading in the left-right direction by the side walls 73W of the receiving recess 73 and the outer side walls 78W of the cover portion 78.

[0093] This embodiment has the following structure. Next, the functions and effects of the wire harness laying device 10 will be described.

[0094] For example, in a wire harness laying device that firmly fixes a wire harness bundling a plurality of electric wires to a movable holding part that can slide and move, when a large load is applied to the electric wires as the movable holding part moves, the bundling member may sink into the electric wires. If the amount of sinking into the electric wires is large, there is a concern of damaging the electric wires.

[0095] Therefore, as a result of the present inventor's intensive research to solve the above problems, the structure of this embodiment was discovered. That is, this embodiment is a wire harness laying device 10 having a wire harness module 20, including: a wire harness 30 in which at least one electric wire 32 is fixed along a strip-shaped base member 34; a holding member 40 that holds a sheet-shaped redundant part 36 different from a wire fixing part (portion) 35 of the base member 34 where the electric wire 32 is fixed; and a protection member 60 that is assembled to a slider 80 that can slide and move. The protection member 60 has a storage part 62 for storing the holding member 40. As Figure 5 and Figure 6 shown, the storage part 62 has a front wall (locking part) 74 and a rear wall (locking part) 75 that can be locked with the holding member 40 in the front-rear direction (the extending direction of the wire harness 30).

[0096] According to the wire harness module 20 having such a structure, the redundant part 36 different from the wire fixing part 35 is held by the holding member 40, and the holding member 40 holding the redundant part 36 is stored in the storage part 62 of the protection member 60. And since the holding member 40 can be locked with the front wall 74 and the rear wall 75 of the storage part 62 in the front-rear direction within the storage part 62, the wire harness 30 can be fixed in such a manner that it does not shift relative to the slider 80.

[0097] In addition, when a load such as pulling the wire harness 30 is applied to the wire harness 30, the load is applied to the redundant part 36 of the wire harness 30, the holding member 40, and the front wall 74 and the rear wall 75 of the protection member 60. That is, it is possible to suppress the application of load to the electric wire 32 and suppress damage to the electric wire 32.

[0098] The holding member 40 of this embodiment has at least one set of a pair of clamping parts 50 that clamp the redundant part 36 from both sides. As Figure 5 shown, each clamping part 50 has a plurality of second protruding parts (protrusions) 54 that protrude toward the redundant part 36.

[0099] That is to say, according to the present embodiment, by causing a plurality of second protrusions 54 in a pair of clamping portions 50 to sink into the redundant portion 36 of the base member 34, it is possible to suppress the wire harness 30 from coming off the protection member 60. In addition, according to such a structure, compared with the case where, for example, a holding member is used to hold the redundant portion in a penetrating manner, it is possible to prevent a reduction in the strength of the redundant portion 36.

[0100] In the present embodiment, a plurality of second protrusions 54 in one clamping portion 50 of the pair of clamping portions 50 and a plurality of second protrusions 54 in the other clamping portion 50 of the pair of clamping portions 50 are arranged in a staggered manner as Figure 5 shown, and the redundant portion 36 is arranged in a meandering manner between the plurality of second protrusions 54 arranged in a staggered manner.

[0101] That is to say, according to the present embodiment, compared with the case where, for example, a plurality of second protrusions are arranged at the same position with the redundant portion 36 as a boundary between a pair of clamping portions, it is possible to increase the degree of sinking of the second protrusions 54 into the redundant portion 36. Thereby, the holding force of the wire harness 30 in the protection member 60 can be improved.

[0102] Five (multiple) wires 32 are arranged and fixed along the base member 34, and redundant portions 36 are respectively formed on both sides of the wire fixing portion 35 where the wires 32 are fixed. As Figure 10 shown, the protection member 60 has a pair of clamping portions 50 that clamp each redundant portion 36. The two pairs of clamping portions 50 are connected by a pair of connecting portions 42, and the pair of connecting portions 42 are further connected by a hinge 43.

[0103] That is to say, according to the present embodiment, it is possible to disperse the load applied to the wire harness 30 to both sides of the wire fixing portion 35 where multiple wires 32 are fixed in the wire harness 30. Therefore, compared with the case where the load is applied to one end portion of the wire harness 30, the burden applied to the redundant portion 36 can be reduced. Thereby, the holding force of the wire harness 30 in the protection member 60 can be improved.

[0104] In addition, according to the present embodiment, the two pairs of clamping portions 50 are connected by a pair of connecting portions 42, and the pair of connecting portions 42 are further connected by a hinge 43. That is to say, since the holding member 40 can be constituted by a single member, compared with the case where each clamping portion is constituted separately, for example, an increase in the number of components can be suppressed, and the assembly operation of assembling the holding member 40 to the wire harness 30 can be simplified.
