[0027] [Details of the embodiments of the present disclosure] Specific examples of the vehicle wiring system and vehicle additional wiring member of 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.

[0028] [Embodiment] <Overall outline of the structure> 1 is a schematic perspective view showing a part of a vehicle 10 in which vehicle wiring systems 20, 40 are incorporated.

[0029] 1, the vehicle 10 includes an instrument panel 12, a center console 14, pillars 16, and a floor 18.

[0030] The instrument panel 12 is located in front of the driver's seat and passenger seat. Instruments 13a such as a speedometer are built into the instrument panel 12. The instrument panel 12 has an upper panel portion 12a facing upward and a rear panel portion 12b facing rearward relative to the forward direction of the vehicle 10. The rear panel portion 12b is connected to the rear edge of the upper panel portion 12a. The rear panel portion 12b is oriented closer to the direction of gravity than the upper panel portion 12a. The upper panel portion 12a and the rear panel portion 12b are connected at an angle or curve. A steering wheel 13b is provided facing rearward from the instrument panel 12.

[0031] The center console 14 is a portion of the instrument panel 12 extending rearward from the center in the vehicle width direction. The center console 14 separates the driver's seat from the passenger seat. The center console 14 may be provided with storage areas for a shift lever, various switches, a drink holder, etc.

[0032] The pillars 16 are parts that support the roof 17 relative to the vehicle body. FIG. 1 shows the frontmost pillar, the so-called A-pillar. The lower end of the pillar 16 is located near the front corner of one side of the instrument panel 12. The upper end of the pillar 16 is located near the front corner of one side of the roof 17.

[0033] The floor 18 is a portion that extends downward and rearward from the center console 14. A floor carpet 18a is laid on the floor 18.

[0034] In this embodiment, a vehicle wiring system 20 is incorporated into the instrument panel 12, and a vehicle wiring system 40 is incorporated into the pillar 16. The vehicle wiring systems 20, 40 will be described separately.

[0035] <About the vehicle wiring system 20> Fig. 2 is a partially enlarged view showing the vehicle wiring system 20. Fig. 2 shows a portion of the left side of the instrument panel 12. Fig. 2 also shows a state in which the additional interior member 30 is separated from the instrument panel 12. Fig. 3 is a cross-sectional view taken along line III-III in Fig. 1. The vehicle wiring system 20 includes the instrument panel 12, the additional wiring member 22, and the additional interior member 30.

[0036] The instrument panel 12 is an example of an interior member facing the passenger compartment. Before additional interior members are added, the interior member is a part that can be observed from inside the passenger compartment. When additional wiring members are added to the interior member, the interior member is partially or entirely covered by the additional wiring members. The instrument panel 12 is formed from resin or the like, and covers the reinforcement 26 and wiring members 27, etc., located in front of the driver's seat and passenger seat, from the passenger compartment side. The reinforcement 26 is an elongated member formed from metal or the like. The reinforcement 26 is a reinforcing member that extends along the vehicle width direction. The wiring members 27 are wiring members that are disposed inside the instrument panel 12 or that are connected to various electrical components 28 assembled to the instrument panel 12. The wiring members 27 extend, for example, along the reinforcement 26 and are connected to the electrical components 28 around the reinforcement 26.

[0037] The electrical component to which the wiring member 27 is connected is, for example, an electrical component that is arranged inside the instrument panel 12 or assembled to the instrument panel 12. For example, the wiring member 27 is connected to an ECU (electronic control unit) that is arranged as an electrical component inside the instrument panel 12. Furthermore, for example, the wiring member 27 may be connected to an instrument 13a, an operation switch, an audio device, or the like that is assembled as an electrical component to the instrument panel 12.

[0038] The additional wiring member 22 is a wiring member that connects electrical components mounted on a vehicle. The additional wiring member 22 includes, for example, at least one electric wire 23. The electric wire 23 has a core wire and a covering surrounding the core wire. The electric wire 23 may be formed by twisting a plurality of electric wires. The electric wire 23 may have a shielding layer on its outer periphery. The additional wiring member may include at least one of a signal line and a power line. In addition to or instead of the electric wire 23 having a core wire covered with a covering, the additional wiring member 22 may include another wiring member, for example, an FPC (Flexible Printed Circuits) in which a circuit made of metal foil is formed on a resin film.

[0039] The additional wiring member 22 is arranged on the instrument panel 12 from the passenger compartment side. In this embodiment, the additional wiring member 22, which includes a plurality of electric wires 23, is arranged on the upward surface of the upper panel portion 12a of the instrument panel 12, extending from one side to the other side of the upper panel portion 12a and bending rearward near the other side. One end of the additional wiring member 22 is guided to the roof 17, for example, through the pillar 16. A connector 22C1 provided at one end of the additional wiring member 22 is connected to a roof electrical component 17E provided on the roof 17. The other end of the additional wiring member 22 is guided toward a lower opening of the instrument panel 12, for example, in front of the passenger seat, and is drawn into the instrument panel 12 through the opening. A connector 22C2 provided at the other end of the additional wiring member 22 is connected to an electrical component 28 in the instrument panel 12.

[0040] The additional interior member 30 covers the additional wiring member 22 from the side opposite to the instrument panel 12. The additional interior member 30 may cover the entire portion of the additional wiring member 22 that is arranged on the instrument panel 12, or may cover only a part of it. In FIG. 1, the additional interior member 30 covers the middle portion of the portion of the additional wiring member 22 that is arranged on the upper panel portion 12a, excluding both end portions.

[0041] In this embodiment, the additional interior member 30 is a sheet that can be deformed to fit the surface shape of the instrument panel 12. The additional interior member 30 may be made of a resin sheet such as polyvinyl chloride or polypropylene. If the additional interior member 30 is a sheet that can be deformed to fit the surface shape of the instrument panel 12, even if the surface shape of the instrument panel 12 is not flat but curved, the additional interior member 30 can bend to fit the curved shape and cover the additional wiring member 22 on the surface of the instrument panel 12.

[0042] The additional interior member 30 may include an impact absorbing layer 32. The impact absorbing layer is a layer with excellent impact absorption properties, such as a foam layer or a nonwoven layer in which multiple fibers are entangled. FIG. 3 shows an example in which the additional interior member 30 has a multi-layer structure made up of a solid layer 31 filled with a content and the impact absorbing layer 32. In this case, it is preferable that the solid layer 31 is located on the passenger compartment side, and the impact absorbing layer 32 is located on the additional wiring member 22 side.

[0043] The additional interior member 30 may have a single layer structure or a multiple layer structure. For example, the additional interior member 30 may have a single layer structure consisting of only the solid layer 31.

[0044] The shape of the additional interior member 30 is arbitrary. For example, the additional interior member 30 may be formed in a band shape extending along the path of the additional wiring member 22. In FIGS. 1 and 2, the additional wiring member 22 extends along an L-shaped path on the upper panel portion 12a, and the additional interior member 30 is also formed in an L-shaped band shape according to this path. The additional interior member 30 may be cut so as to bend along the path. The additional interior member 30 may be formed so as to follow the curved path by bending a member formed in a straight band shape or by connecting multiple straight band-shaped members.

[0045] The additional interior member 30 may have a shape that extends along a linear path, or may have a shape that spreads widely regardless of the path of the additional wiring member 22. For example, the additional interior member 30 may be in the form of a sheet that spreads over the entire upper panel portion 12a. The additional interior member 30 may be a sheet that can be cut with scissors, a cutter, or the like. In this case, the additional interior member 30 can be easily cut according to the path of the additional wiring member 22, the outer shape of the upper panel portion 12a, etc.

[0046] Fig. 4 shows an additional interior member 130 according to a modified example in which the shape of the additional interior member 30 is changed. In this modified example, the additional wiring member 22 is arranged on the upper panel portion 12a so as to extend from a front portion of one side edge of the upper panel portion 12a along the entire front edge of the upper panel portion 12a and further along the other side edge of the upper panel portion 12a. The portion of the additional wiring member 22 that extends along the entire front edge of the upper panel portion 12a is a portion that extends along the vehicle width direction.

[0047] The additional interior member 130 is formed in a strip shape along the path of the additional wiring member 22, extending from a portion of the front side of one side edge of the upper panel portion 12a along the entire front edge of the upper panel portion 12a and further along the other side edge of the upper panel portion 12a. A portion 130B of the additional interior member 130 extending from a portion of the front side of the upper panel portion 12a along the entire front edge of the upper panel portion 12a is an example of a portion that covers the instrument panel 12 over the entire width of the instrument panel 12. The outer edge of portion 130B in the vehicle width direction coincides with the outer edge of the instrument panel 12 in the vehicle width direction, making the additional interior member 130 less noticeable on the instrument panel 12.

[0048] Furthermore, the front edge and the outer edge in the vehicle width direction of the peripheral edges of the additional interior member 130 are aligned with the front edge and outer edge of the instrument panel 12. By having at least a portion of the edge of the additional interior member 130 aligned with the edge of the additional interior member 130, the edge becomes less noticeable.

[0049] If the front side of one side edge of the upper panel portion 12a is defined as a first edge portion, and the front side of the other side edge of the upper panel portion 12a is defined as a second edge portion, the additional wiring member 22 includes a portion extending from the first edge portion toward the second edge portion. It can also be said that the additional interior member 130 covers the entire portion of the additional interior member 30 between the first edge portion and the second edge portion. The additional wiring member 22 is inconspicuous, and the portions of the additional interior member 130 on the first and second edge portion sides blend in with the first and second edge portions of the upper panel portion 12a and are therefore inconspicuous.

[0050] If the additional interior member extends over the same area as the upper panel portion 12a, the entire edge around the additional interior member will follow the outer edge of the upper panel portion 12a and the boundary between the upper panel portion 12a and the rear panel portion 12b, making the additional interior member less noticeable.

[0051] If at least a part of the edge of the additional interior member is along at least a part of the edge of the interior member, the additional interior member will be less noticeable. In this case, the edge of the interior member may be along the boundary between the interior member and another interior member when the interior member is adjacent to the other interior member.

[0052] The surface color of the additional interior member 30 may be the same color family as the surface color of the instrument panel 12. For example, if colors are divided into 13 groups according to JIS Z 8102:2001, including the achromatic colors of white, gray, and black, and the chromatic colors of red, yellow-red, yellow, yellow-green, green, blue-green, blue, blue-purple, purple, and red-purple, colors belonging to the same group may be considered to be of the same group.

[0053] The surface design texture of the additional interior member 30 may be the same as the surface design texture of the instrument panel 12, which is also an interior member. The design texture refers to the surface pattern, processing state, and detailed surface shape of an object that can make an impression on the eye. For example, if the surface of the instrument panel 12 has a wood grain pattern, marble pattern, grain pattern, matte pattern, glossy surface, or metallic surface, the surface of the additional interior member 30 should preferably have the same pattern or texture as the surface of the instrument panel 12.

[0054] The additional interior member 30 is attached to the instrument panel 12 or a member around it, while covering the additional wiring member 22. In this example, the additional interior member 30 is attached to the surface of the instrument panel 12. The attachment may be performed using an adhesive layer or a hook-and-loop fastener.

[0055] The adhesive layer may be an adhesive layer formed on both sides of a base material, such as double-sided tape, or may be made of an adhesive. In FIG. 3 , double-sided tape 38 is attached to instrument panel 12. A plurality of parallel-arranged electric wires 23 are attached to the double-sided tape 38. Additional interior members 30 are attached to the double-sided tape 38, protruding from both sides of the parallel-arranged electric wires 23. If the additional wiring member is an adhesive tape-like member having an adhesive layer formed on one main surface of a strip-shaped base material, the additional wiring member may be attached to the plurality of electric wires 23, and the adhesive layer exposed on both sides of the additional wiring member 22 may be attached to instrument panel 12.

[0056] The additional interior member 30 may be attached to a member around the instrument panel 12. The additional interior member 30 may be attached to the instrument panel 12 or a member around it by a hook structure such as a clip or a locking structure.

[0057] The hook-and-loop fastener is a flat member having a plurality of hook-shaped members. The hook-and-loop fastener is a member that detachably hooks onto a mating member by hooking the hook-shaped members onto a loop-shaped portion or fiber of the mating member. The hook-and-loop fastener may be glued or sewn to the additional interior member 30. The mating member may be glued to the instrument panel 12. When the interior member has loop-shaped portions or fibers, the additional interior member is detachably attached directly to the interior member by the hook-and-loop fastener.

[0058] FIG. 2 shows an example in which an additional wiring member 222 and an additional interior member 230 are attached to a floor carpet 18a, which is an example of an interior member. The floor carpet 18a is, for example, a carpet in which multiple fibers are entangled or a carpet that has been subjected to a loop-like raised treatment. The floor carpet 18a covers a metal vehicle body floor. The floor carpet 18a may also cover a wiring member disposed on the vehicle body floor. The floor carpet 18a is an example of an interior member that faces the passenger compartment. The additional wiring member 222 is disposed on the floor carpet 18a. The additional interior member 230 is disposed on the floor carpet 18a so as to cover the additional wiring member 222. A hook-and-loop fastener 232 is attached to one main surface of the additional interior member 230 by bonding, sewing, or the like. On both sides of the additional wiring member 222, the hook-shaped members of the hook-and-loop fastener 232 are caught on loops formed by the fibers or the raising treatment of the floor carpet 18a, so that the additional interior member 230 is detachably attached to the floor carpet 18a while covering the additional wiring member 222.

[0059] The additional wiring member 222 may include a portion extending from the first edge portion toward the second edge portion of the floor carpet 18a. The second edge portion is a portion spaced apart from the first edge portion. For example, the first and second edge portions may be the left and right edges of the floor carpet 18a, and the additional wiring member 22 may be disposed across the vehicle width direction. Alternatively, the first and second edge portions may be the front and rear edges of the floor carpet 18a, and the additional wiring member 22 may be disposed across the vehicle front-to-rear direction. Alternatively, the first edge portion may be the front or rear edge of the vehicle, and the second edge portion may be the right or left edge of the vehicle, and the additional wiring member 222 may be disposed in a curved manner extending from the front or rear of the vehicle toward the side. Between the first and second edge portions, the additional wiring member 222 may have a circuitous path portion.

[0060] In this case, the additional interior member may cover the entire portion of the additional wiring member 222 between the first edge portion and the second edge portion, and may also cover the floor carpet 18a.

[0061] As a result, at least a part of the outer peripheral edge of the additional interior member blends into the first edge portion and the second edge portion, making both the additional wiring member 222 and the additional interior member less noticeable. Also, because the additional wiring member 222 is covered by the additional interior member, it is possible to prevent the additional wiring member 222 from being broken by being stepped on and to prevent the additional wiring member 222 from being waterproofed.

[0062] <About the vehicle wiring system 40> Fig. 5 is a partially enlarged view showing the vehicle wiring system 40. Fig. 5 shows the additional liner 50 separated from the pillar 16. Fig. 6 is an explanatory diagram showing the positional relationship among the pillar 16, wiring member 47, additional wiring member 42, and additional liner 50 in a cross section taken along line VI-VI in Fig. 1. The vehicle wiring system 40 is applied to the pillar 16, and includes a liner 16b and the additional liner 50.

[0063] Here, the pillar 16 will be described. The pillar 16 includes a metal pillar 16a and a liner 16b that covers the metal pillar 16a from the passenger compartment side. The metal pillar 16a is part of the metal body. The metal pillar 16a has an outer surface that is exposed to the outside of the vehicle body. A metal reinforcing member 16r may be welded to the passenger compartment side of the metal pillar 16a to support the roof 17. The liner 16b is a member formed from resin or the like. The liner 16b is formed, for example, in a semi-cylindrical shape. Both ends of the liner 16b are positioned corresponding to the upper and lower ends of the metal pillar 16a. Both side edges of the liner 16b are positioned along both side edges of the metal pillar 16a. The liner 16b is attached to the metal pillar 16a, for example, by a fitting structure. For example, a locking member 16D having locking claws 16Da protrudes from the inner surface of the liner 16b. The metal reinforcing member 16r has formed therein a locking hole 16rh into which the locking member 16D is fitted and locked. The locking member 16D is locked into the locking hole 16rh, thereby attaching the liner 16b to the metal pillar 16a. The structure for attaching the liner 16b to the metal pillar 16a is not limited to the above example. For example, the liner 16b may be attached to the metal pillar 16a by fitting both side edges of the liner 16b into grooves formed in both side edges of the metal pillar 16a. Alternatively, the liner 16b may be attached to the metal pillar 16a by screws, adhesive, pressure-sensitive adhesive, etc.

[0064] When the liner 16b is attached to the metal pillar 16a, a space in which the wiring member 47 can be placed is formed between the metal pillar 16a and the liner 16b. For example, the metal pillar 16a is formed in a semi-cylindrical shape, and the liner 16b is also formed in a semi-cylindrical shape. When the metal pillar 16a and the liner 16b are combined, a long and narrow space is formed between them. Within the long and narrow space, a long and narrow space S1 in which the wiring member 47 can be placed is formed outside the metal reinforcing member 16r. The liner 16b is a rigid member made of a resin such as polypropylene, and can maintain the space S1 in a constant shape. The liner 16b is an example of an interior member that faces the passenger compartment.

[0065] A wiring member 47 is disposed within the space S1. The wiring member 47 includes, for example, a plurality of electric wires 47a and extends along the pillar 16. One end of the wiring member 47 is connected to an electric component (e.g., a lamp, a camera, etc.) on the roof 17 side via a connector or the like, and the other end of the wiring member 47 is connected to an electric component (e.g., an ECU, a battery, etc.) below the roof 17 via a connector or the like.

[0066] An additional wiring member 42 is disposed on the liner 16b. The additional wiring member 42 is a wiring member that connects electrical components mounted on a vehicle. The additional wiring member 42 includes, for example, at least one electric wire 43. In this embodiment, the additional wiring member 42 is provided on an extension of the additional wiring member 22. The additional wiring member 42 may be a wiring member separate from the additional wiring member 22. The additional wiring member 42 may include a wiring member other than the electric wire 43, for example, an FPC (Flexible Printed Circuits) in which a circuit made of metal foil is formed on a resin film.

[0067] The additional wiring member 42 is arranged on the liner 16b from the passenger compartment side. In this embodiment, the additional wiring member 42, which includes a plurality of electric wires 43, is arranged on the passenger compartment-facing surface of the liner 16b, extending from the lower end to the upper end of the liner 16b. One end of the additional wiring member 42 is connected to a roof electrical component 17E provided on the roof 17, for example, via a connector 22C1 or the like. The other end of the additional wiring member 42 is connected to an electrical component 28 located lower than the pillar 16, for example, via a connector 22C2 or the like.

[0068] The additional liner 50 covers the additional wiring member 42 from the side opposite to the liner 16b. The additional liner 50 may cover the entire portion of the additional wiring member 42 that is disposed on the liner 16b, or may cover only a part of it. In this embodiment, the additional liner 50 covers the additional wiring member 42 over the entire longitudinal direction of the pillar 16.

[0069] In the present embodiment, the additional liner 50 has a degree of rigidity that allows a space S2 for arranging the additional wiring member 42 to be formed between the liner 16b and the additional liner 50. For example, the additional liner 50 is made of a resin such as polypropylene, and has a thickness that allows the space S2 to be maintained. Therefore, even if a human hand touches the additional liner 50 from the vehicle interior side, the space S2 is maintained at a constant size, and the additional wiring member 42 in the space S2 is unlikely to be compressed.

[0070] The additional liner 50 may be formed, for example, in a semi-cylindrical shape that can form the space S2 on the passenger compartment side of the liner 16b. When the additional liner 50 covers the passenger compartment side of the liner 16b, a space S2 with a crescent-shaped cross section is formed between the passenger compartment side surface of the liner 16b and the additional liner 50. Both side edges of the additional liner 50 may extend along both side edges of the liner 16b. This makes the additional liner 50 less noticeable when the pillar 16 is viewed from the passenger compartment side.

[0071] The surface color of the additional liner 50 may be the same color as the surface color of the liner 16b. The design texture of the surface of the additional liner 50 may be the same as the design texture of the surface of the liner 16b. Since the surface of the liner 16b has a uniform appearance with the entire interior, even if the additional liner 50 covers the entire liner 16b, the additional liner 50 is unlikely to stand out if the surface of the additional liner 50 has the above-mentioned properties.

[0072] The additional liner 50 is attached to the liner 16b or a surrounding member while covering the additional wiring member 42. In this example, the additional liner 50 is attached to the surface of the liner 16b. The attachment may be performed by an adhesive layer 58 or a hook-and-loop fastener.

[0073] The adhesive layer may be an adhesive layer formed on both sides of a base material, such as a double-sided tape, or may be an adhesive layer formed by applying a coated adhesive. In Fig. 6, adhesive layers 58 made of double-sided tape or the like are formed on both side edges of the surface of the additional liner 50 facing the liner 16b, and the adhesive layers 58 are adhered to both side surfaces of the surface of the liner 16b facing the passenger compartment.

[0074] The additional liner 50 may be attached to the liner 16b or surrounding components by adhesive, hooking structures, or the like.

[0075] <Effects, etc.> With the wiring systems 20, 40, the vehicle additional wiring member including the additional wiring member 22 and the additional interior member 30, or the vehicle additional wiring member including the additional wiring member 42 and the additional liner 50 configured as described above, the additional wiring member 22, 42 can be placed on the interior member, such as the instrument panel 12 or the liner 16b, and then covered with the additional interior member 30 or the additional liner 50. This allows the additional wiring member 22, 42 to be easily added to the vehicle in an inconspicuous manner without having to first remove the instrument panel 12 or the liner 16b. Furthermore, because the additional wiring member 22, 42 is covered by the additional interior member 30 or the additional liner 50, it is possible to prevent the additional wiring member 22, 42 from coming apart and getting caught on surrounding objects or people, and it is possible to keep the additional wiring member 22, 42 along a fixed path.

[0076] Furthermore, the instrument panel 12 or the liner 16b, which are interior components, cover the wiring members 27, 47, and the additional wiring members 22, 42 are arranged along a path separate from the wiring members 27, 47. Therefore, the additional wiring members 22, 42 can be added without modifying the existing wiring members 27, 47. Because there is no need to modify the existing wiring members 27, 47, it is possible to prevent the position of the wiring members 27, 47 from being changed, thereby preventing an increase in the influence of noise.

[0077] Therefore, when another electrical component is to be added to an existing vehicle, the present wiring systems 20, 40 are suitable as systems for easily adding additional wiring members 22, 42 for the electrical component.

[0078] Furthermore, since the additional interior member 130 includes a portion that covers the instrument panel 12 over the entire width of the instrument panel 12, it is unlikely that an interrupted portion of the additional interior member 130 will occur in the middle of the instrument panel 12 in the vehicle width direction, and the outer peripheral edge of the additional interior member 130 will not be noticeable.

[0079] Furthermore, if the additional interior member 30 is a sheet that can be deformed to fit the surface shape of the instrument panel 12, the additional interior member 30 can be easily arranged along the surface of the interior member, regardless of the surface shape of the interior member.

[0080] Furthermore, if the additional liner 50, which is the additional interior member, is a member having a degree of rigidity that allows for the formation of a space S2 for arranging the additional wiring member 42 between the liner 16b and the additional liner 50, then the space S2 for arranging the additional wiring member 42 can be easily provided by arranging the additional liner 50 on the liner 16b. Furthermore, by providing the space S2, external force is less likely to be applied to the additional wiring member 42, and disturbance in the arrangement of the additional wiring member 42 is suppressed.

[0081] If the interior member is a liner 16b on the pillar 16 and the additional wiring member is an additional liner 50 that covers the liner 16b from the passenger compartment side, the additional wiring member 42 that runs along the pillar 16 can be easily added without peeling off the liner 16b.

[0082] Furthermore, if the surface color of the additional interior member 30 or the additional liner 50 is the same color as the surface color of the instrument panel 12 or the liner 16b, the additional interior member 30 or the additional liner 50 will be less noticeable.

[0083] Furthermore, if the design texture of the surface of the additional interior member 30 or the additional liner 50 is the same as the design texture of the surface of the interior member, the additional interior member 30 or the additional liner 50 will be less noticeable.

[0084] Furthermore, if at least a portion of the edge of the additional interior member 130 or the additional liner 50 is aligned with the edge of the instrument panel 12 or the liner 16b, the additional interior member 130 or the additional liner 50 will be less noticeable.

[0085] Furthermore, if the additional interior member 30 includes the impact absorbing layer 32, the impact on the additional wiring member 22 is absorbed by the impact absorbing layer 32, and the impact is less likely to act on the additional interior member 30 inside.

[0086] Furthermore, if the additional interior member 30 or the additional liner 50 is kept covering the additional wiring members 22, 42 with an adhesive layer (for example, double-sided tape 38, adhesive layer 58), the additional interior member 30 or the additional liner 50 can be easily attached to the instrument panel 12 or the liner 16b. For example, even if the instrument panel 12 or the liner 16b does not have to be provided with a structure for attaching the additional interior member 30 or the additional liner 50 in advance, the additional interior member 30 or the additional liner 50 can be easily attached later.

[0087] [Variations] In the above embodiment, the configuration related to the vehicle wiring system 20 and the configuration related to the vehicle wiring system 40 may be combined. For example, an additional interior member formed of a rigid member may cover the additional wiring member 22 on the instrument panel 12. In this case, the additional interior member may be in a strip shape that follows the path of the wiring member, or may have a shape that covers the entire upper panel portion 12a of the instrument panel 12. Also, an additional interior member that is flexible enough to be deformable along the surface of the liner 16b may cover the additional wiring member 22 on the liner 16b.

[0088] In the above embodiment, examples have been shown in which the interior member is the instrument panel, the floor carpet, or the liner 16b of the pillar 16. The interior member may also be the center console 14, a roof liner, or the like.

[0089] The additional liner 50 may also include a shock absorbing layer.

[0090] The configurations described in the above embodiment and modifications can be combined as appropriate as long as they are not mutually contradictory. [Explanation of symbols]
