Embodiments for Carrying Out the Invention

[0009] [Description of Embodiments of the Present Disclosure] First, embodiments of the present disclosure will be listed and described. The wire attachment member of the present disclosure is [1] A wire attachment member for attaching a wire disposed in the passenger compartment of a vehicle to a passenger compartment component member constituting the passenger compartment, comprising a seat member and an elastic member provided on the seat member, wherein the seat member has a wire holding portion configured to surround and hold the wire by folding back an end portion of the seat member, and the elastic member is configured to be fixed to the passenger compartment component member by being sandwiched in a compressed state between sandwiching portions of the passenger compartment component member.

[0010] According to this configuration, since the outer periphery of the wire is surrounded by the wire holding portion formed by folding back the end portion of the seat member, the wire can be protected by the wire holding portion of the wire attachment member. And, by sandwiching the elastic member in the wire attachment member between the sandwiching portions of the passenger compartment component member, the wire attachment member can be attached to the passenger compartment component member. Therefore, it becomes possible to attach the wire by the wire attachment member without detaching the passenger compartment component member, and as a result, it becomes possible to easily attach the wire in the passenger compartment.

[0011] [2] In the above [1], the end portion of the seat member forming the wire holding portion may be folded back and detachably fixed to the surface of the seat member. According to this configuration, by opening and closing the wire holding portion by attaching and detaching the end portion of the seat member, it becomes possible to increase or decrease the number of wires held by the wire holding portion.

[0012] [3] In the above [1] or [2], the elastic member may be formed of a porous material. According to this configuration, it becomes possible to preferably sandwich and fix the elastic member formed of the porous material between the sandwiching portions of the passenger compartment component member.

[0013] [4] In any one of the above [1] to [3], when the sheet member is used as the first sheet member and the wire holding portion is used as the first wire holding portion, the wire attachment member includes a second sheet member attached to the first sheet member. The second sheet member may have a second wire holding portion configured to surround and hold a wire different from the wire held by the first wire holding portion by folding back an end portion of the second sheet member.

[0014] According to this configuration, when adding an additional wire in the passenger compartment, it is possible to easily attach the additional wire simply by attaching the second sheet member for holding the additional wire to the first sheet member.

[0015] [5] In any one of the above [1] to [4], the passenger compartment component member includes a vehicle body panel and an interior component that cooperate with each other to function as the clamping portion, and the elastic member may be configured to be fixable to the passenger compartment component member by being sandwiched in a compressed state between the vehicle body panel and the interior component.

[0016] According to this configuration, it is possible to easily attach the wire attachment member simply by sandwiching the elastic member of the wire attachment member between the vehicle body panel and the interior component. [6] The wire harness of the present disclosure includes the wire attachment member according to any one of the above [1] to [5], a wire attached to the passenger compartment component member constituting the passenger compartment of the vehicle by the wire attachment member.

[0017] According to this configuration, the same operational effects as those of the above wire attachment member can be achieved. [7] The wire harness routing structure of the present disclosure includes the wire harness according to the above [6] and a passenger compartment component member constituting the passenger compartment of the vehicle, and the wire attachment member in the wire harness is attached to the passenger compartment component member.

[0018] According to this configuration, the same operational effects as those of the above wire attachment member can be achieved. [Details of Embodiments of the Present Disclosure] Specific examples of the wire attachment member, wire harness, and wire harness routing structure of the present disclosure will be described below with reference to the drawings. In each drawing, for convenience of explanation, a part of the configuration may be shown exaggerated or simplified. Also, the dimensional ratios of each part may be different in each drawing. Note that terms such as "first", "second", "third", "fourth", etc. in this specification are used merely to distinguish objects and do not rank the objects. Note that the present invention is not limited to these examples, is defined by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0019] (Overall configuration of wire harness routing structure 10) As shown in FIG. 1, the wire harness routing structure 10 of the present embodiment includes a passenger compartment component 13 that forms part of the passenger compartment 12 of the vehicle 11 and a wire harness 14 routed within the passenger compartment 12.

[0020] The wire harness 14 has an electric wire 15 and a wire attachment member 16 that holds the electric wire 15 and is fixed to the passenger compartment component 13. The wire attachment member 16 regulates the routing path of the electric wire 15 disposed within the passenger compartment 12 of the vehicle 11. The wire harness 14 includes one or a plurality of electric wires 15. The electric wires 15 electrically connect a first electrical device E1 and a second electrical device E2 that are both attached to the vehicle 11.

[0021] Examples of the first electrical device E1 include sensor devices such as imaging devices. The first electrical device E1 is provided, for example, at a position closer to the rear of the passenger compartment 12 in the vehicle 11, such as a back door of the vehicle 11.

[0022] Examples of the second electrical device E2 include an electronic control unit (ECU) and the like. The second electrical device E2 is provided, for example, inside or outside the passenger compartment 12 at a position near the front of the passenger compartment 12. Note that the passenger compartment 12 is a room in the vehicle 11 where passengers including the driver board.

[0023] The electric wire 15 connecting the first electric device E1 and the second electric device E2 is routed inside the passenger compartment 12. The wire attachment member 16 partially protects the electric wire 15 routed inside the passenger compartment 12 by covering a predetermined range in the length direction of the electric wire 15. Further, the wire attachment member 16 holds the electric wire 15 to the passenger compartment component 13.

[0024] (Configuration of the passenger compartment component 13) As shown in FIG. 2, the passenger compartment component 13 includes, for example, a vehicle body panel 17 and an interior component 18. The vehicle body panel 17 is made of, for example, metal, and the interior component 18 is made of, for example, synthetic resin. Further, for example, the vehicle body panel 17 is a floor tunnel located between the driver's seat and the passenger seat of the vehicle 11, and the interior component 18 is a console provided on the floor tunnel.

[0025] (Configuration of the wire attachment member 16) As shown in FIGS. 2 and 3, the wire attachment member 16 includes a sheet member 21 and an elastic member 22 provided on the sheet member 21. The sheet member 21 is a flexible sheet-like member. The sheet member 21 is formed of, for example, synthetic resin. The sheet member 21 has a wire holding portion 23 configured to surround and hold the electric wire 15 when an end portion 21a of the sheet member 21 is folded back. The sheet member 21 has a first surface 21b and a second surface 21c that are in a front-back relationship with each other.

[0026] The elastic member 22 is fixed to, for example, the first surface 21b of the sheet member 21. The elastic member 22 is formed of, for example, a porous material such as sponge. The elastic member 22 has, for example, a rectangular parallelepiped shape that is long in one direction. The elastic member 22 is provided on the first surface 21b in a manner such that its longitudinal direction is along one of the four sides of the sheet member 21 whose shape is a rectangle. The end portion 21a of the sheet member 21 is an end portion corresponding to the side opposite to the side on which the elastic member 22 is provided among the four sides of the sheet member 21.

[0027] FIG. 4 shows the process of wrapping and holding the electric wire 15 with the sheet member 21. As shown in FIG. 4, in the sheet member 21 of the present embodiment, for example, a joint portion 24 along the end portion 21a is provided on the first surface 21b. Then, while sandwiching the electric wire 15 so that the first surfaces 21b face each other, the end portion 21a is folded back, and the joint portion 24 is joined to the first surface 21b. Thereby, a tubular electric wire holding portion 23 surrounding the outer periphery of the electric wire 15 is formed. Examples of the joint portion 24 include a double-sided tape, a hook-and-loop fastener, a button, and the like.

[0028] The joint portion 24 can be joined at an arbitrary position within a joinable range A1 from the joint portion 24 to the elastic member 22 on the first surface 21b. Also, the joint portion 24 is detachable with respect to the joinable range A1. That is, the end portion 21a of the sheet member 21 having the joint portion 24 is detachable from the first surface 21b of the sheet member 21. And by changing the joining position of the end portion 21a within the joinable range A1, it is possible to change the size of the accommodation space formed inside the electric wire holding portion 23. For this reason, as shown in FIG. 5, it is also possible to hold a plurality of electric wires 15 inside the electric wire holding portion 23.

[0029] As shown in FIGS. 2 and 3, the electric wire attachment member 16 is attached to the passenger compartment constituent member 13 when the elastic member 22 is sandwiched in a compressed state by the sandwiching portion 13a in the passenger compartment constituent member 13. The sandwiching portion 13a of the passenger compartment constituent member 13 is constituted by, for example, the vehicle body panel 17 and the interior component 18. That is, the elastic member 22 is configured to be fixable to the passenger compartment constituent member 13 by being sandwiched in a compressed state between the vehicle body panel 17 and the interior component 18. In the wire harness routing structure 10 of the present embodiment, for example, in a state where the elastic member 22 of the electric wire attachment member 16 is sandwiched and fixed by the sandwiching portion 13a, the electric wire holding portion 23 is configured to be located below the elastic member 22 in the vertical direction. Also, the combined thickness of the elastic member 22 and the sheet member 21 is set to be larger than the interval between the vehicle body panel 17 and the interior component 18 in the sandwiching portion 13a.

[0030] (Operation of this Embodiment) The operation of this embodiment will be described below. When attaching the first electrical device E1 to the vehicle 11, the wire attachment member 16 is used when arranging the wire 15 extending from the first electrical device E1 inside the passenger compartment 12.

[0031] When attaching the wire 15 to the wire attachment member 16, first, the end portion 21a of the seat member 21 is folded back so as to wrap the wire 15, and the joint portion 24 is joined to the first surface 21b. As a result, the wire 15 is held in a manner surrounded by the wire holding portion 23.

[0032] When attaching the wire attachment member 16 to the passenger compartment component member 13, a part of the elastic member 22 and the seat member 21 in the wire attachment member 16 are pushed between the vehicle body panel 17 and the interior component 18 that constitute the clamping portion 13a. As a result, the elastic member 22 is sandwiched between the vehicle body panel 17 and the interior component 18 in a compressed state, and as a result, the wire attachment member 16 is less likely to fall off.

[0033] Regarding the procedure for forming the wire harness routing structure 10, the order of attaching the wire 15 to the wire attachment member 16 and attaching the wire attachment member 16 to the clamping portion 13a does not matter. That is, after attaching the wire 15 to the wire attachment member 16, the wire attachment member 16 may be attached to the passenger compartment component member 13. Also, the wire 15 may be attached to the wire attachment member 16 that has been previously attached to the passenger compartment component member 13.

[0034] The routing path of the wire 15 inside the passenger compartment 12 is regulated by the wire attachment member 16 attached to the passenger compartment component member 13 as described above. As a result, it is possible to suppress interference with the wire 15 such as the passenger or peripheral components getting caught on the wire 15.

[0035] (Effect of this Embodiment) The effect of this embodiment will be described below. (1) Since the outer periphery of the electric wire 15 is surrounded by the electric wire holding portion 23 formed by folding back the end portion 21a of the sheet member 21, the electric wire holding portion 23 of the electric wire attachment member 16 can protect the electric wire 15. Then, by sandwiching the elastic member 22 in the electric wire attachment member 16 between the sandwiching portions 13a of the passenger compartment constituent member 13, the electric wire attachment member 16 can be attached to the passenger compartment constituent member 13. Therefore, the electric wire attachment member 16 enables the attachment of the electric wire 15 without detaching the passenger compartment constituent member 13, and as a result, the electric wire 15 can be easily attached into the passenger compartment 12.

[0036] (2) The end portion 21a of the sheet member 21 forming the electric wire holding portion 23 is folded back and detachably fixed to the first surface 21b of the sheet member 21. According to this configuration, by opening and closing the electric wire holding portion 23 by attaching and detaching the end portion 21a of the sheet member 21, the number of electric wires 15 held by the electric wire holding portion 23 can be increased or decreased.

[0037] (3) The elastic member 22 is formed of a porous material. According to this configuration, the elastic member 22 formed of the porous material can be preferably sandwiched and fixed by the sandwiching portion 13a of the passenger compartment constituent member 13.

[0038] (4) The passenger compartment constituent member 13 includes a vehicle body panel 17 and an interior component 18 that cooperate with each other to function as the sandwiching portion 13a. The elastic member 22 is configured to be fixable to the passenger compartment constituent member 13 by being sandwiched in a compressed state between the vehicle body panel 17 and the interior component 18. According to this configuration, the electric wire attachment member 16 can be easily attached only by sandwiching the elastic member 22 of the electric wire attachment member 16 between the vehicle body panel 17 and the interior component 18.

[0039] (Other embodiments) The above embodiments can be implemented with the following modifications. The above embodiments and the following modification examples can be implemented in combination with each other within a technically non - conflicting range.

[0040] ·The wire attachment member 16 in the above-described embodiment can be changed to a configuration as shown in FIGS. 6 and 7, for example. The wire attachment member 16A shown in FIGS. 6 and 7 includes a first sheet member 30, a second sheet member 40, and an elastic member 22 provided on the first sheet member 30. The first sheet member 30 has the same configuration as the sheet member 21 in the above-described embodiment. Therefore, for the configuration related to the first sheet member 30, the same reference numerals are given to the same configurations as those in the above-described embodiment, and the detailed description thereof is omitted. The first sheet member 30 has a first wire holding portion 31 having the same configuration as the wire holding portion 23 in the above-described embodiment. That is, the wire 15 is surrounded and held by the first wire holding portion 31.

[0041] The second sheet member 40 is a flexible sheet-like member. The second sheet member 40 is formed of, for example, a synthetic resin. The second sheet member 40 is formed of, for example, the same material as the first sheet member 30. The second sheet member 40 has a second wire holding portion 41 that surrounds and holds a wire 15a different from the wire 15 held by the first wire holding portion 31.

[0042] The second sheet member 40 has a third surface 40b and a fourth surface 40c that are in a front-back relationship with each other. The second wire holding portion 41 is formed in a cylindrical shape that surrounds the outer periphery of the wire 15a by folding back the end portion 40a of the second sheet member 40 and joining it to the third surface 40b of the second sheet member 40. Note that the end portion 40a of the second sheet member 40 may be configured to be detachable from the third surface 40b by a second joining portion 42. Examples of the second joining portion 42 include double-sided tape, hook-and-loop fastener, buttons, and the like.

[0043] The second sheet member 40 can be attached to the first surface 21b of the first sheet member 30. For example, the fourth surface 40c of the second sheet member 40 can be joined to the joinable range A1 on the first surface 21b of the first sheet member 30 by the third joining portion 43. Also, the second sheet member 40 is configured to be detachable from the joinable range A1 by the third joining portion 43. Examples of the third joining portion 43 include double-sided tape, hook-and-loop fasteners, buttons, and the like.

[0044] According to the above configuration, the wire attachment member 16A includes a second sheet member 40 attached to the first sheet member 30. The second sheet member 40 has a second wire holding portion 41 configured to surround and hold the wire 15a when an end portion 40a of the second sheet member 40 is folded back. According to this configuration, when adding an additional wire 15a in the passenger compartment 12, it is possible to easily attach the additional wire 15a simply by attaching the second sheet member 40 that holds the additional wire 15a to the first sheet member 30.

[0045] In the above configuration, the end portion 40a of the second sheet member 40 that forms the second wire holding portion 41 may be non-detachably joined to the third surface 40b of the second sheet member 40. Also, the second sheet member 40 may be non-detachably joined to the first surface 21b of the first sheet member 30. Further, the second sheet member 40 may be attached to the end portion 21a joined to the first surface 21b of the first sheet member 30. Additionally, the second sheet member 40 may be attached to the second surface 21c of the first sheet member 30.

[0046] ·In the above embodiment, the end portion 21a of the sheet member 21 that forms the wire holding portion 23 may be non-detachably joined to the first surface 21b of the sheet member 21. · In the wire attachment member 16 of the above-described embodiment, a wire holding portion 23 may be formed by joining the end portion 21a of the sheet member 21 to the second surface 21c. Since the elastic member 22 is not provided on the second surface 21c, the range where the end portion 21a can be joined is wider than that of the first surface 21b. Therefore, it is possible to configure the size of the accommodation space formed inside the wire holding portion 23 to be larger.

[0047] · The configuration such as the number and shape of the elastic members 22 provided on the sheet member 21 is not limited to the above-described embodiment and can be changed as appropriate. Further, the elastic member 22 is not limited to being formed of a porous material. For example, rubber that is not a porous material may be used as the elastic member 22.

[0048] · The number of wires 15 held by the wire attachment member 16 is not limited to the above-described embodiment and can be changed as appropriate. · In the above-described embodiment, a console is given as an example of the interior component 18 that constitutes the sandwiching portion 13a of the passenger compartment component 13. However, for example, a trim or the like that constitutes a part of the passenger compartment 12 may be used instead.

[0049] · In the above-described embodiment, a floor tunnel is given as an example of the vehicle body panel 17 that constitutes the sandwiching portion 13a of the passenger compartment component 13. However, the present invention is not limited to this, and a vehicle body panel other than the floor tunnel may be used.

[0050] · In the passenger compartment component 13 of the above-described embodiment, the sandwiching portion 13a that sandwiches the elastic member 22 is constituted by two components (the vehicle body panel 17 and the interior component 18). However, the present invention is not particularly limited to this. For example, a sandwiching portion that sandwiches the elastic member 22 may be constituted by a recess existing in one member included in the passenger compartment component 13.

[0051] · The embodiments disclosed this time are illustrative in all respects, and the present invention is not limited to these illustrations. That is, the scope of the present invention is shown by the claims, and it is intended that all modifications within the meaning and scope equivalent to the claims are included.
