[0010] [Description of the embodiments of the present disclosure] First, embodiments of the present disclosure will be listed and described.

[0011] The wiring member assembly of the present disclosure is as follows.

[0012] (1) A wiring member assembly including an interior member facing the passenger compartment and a wiring member held by the interior member so as to run along the interior member, the wiring member including an inner section covered by the interior member and an outer section extending from the interior member, the inner section being longer than the length of a wiring path in the interior member.

[0013] In this wiring member assembly, the inner section of the wiring member is longer than the length of the wiring path in the interior member. Therefore, when the airbag arranged inside the interior member deploys, the interior member can move so that part of the inner section is pulled out from the interior member. Therefore, when the wiring member is held by the interior member, the airbag arranged inside the interior member can deploy smoothly.

[0014] (2) In the wiring member assembly of (1), the interior member is an elongated interior member for a pillar that covers the pillar body from the passenger compartment side, the wiring member is held by the interior member for a pillar so that the inner section is along the longitudinal direction of the interior member for a pillar, and the outer section has a first outer section extending from one end of the interior member for a pillar and a second outer section extending from the other end of the interior member for a pillar, and the inner section may be longer than the interior member for a pillar.

[0015] In this case, the first outer section and the second outer section extending from one end and the other end of the pillar interior member can be used to electrically connect the roof-side equipment of the vehicle to equipment below the roof. Furthermore, when an airbag disposed inside the pillar interior member deploys, the pillar interior member can move by pulling out part of the inner section from one end or the other end of the pillar interior member. Therefore, when the wiring member is held by the pillar interior member, the airbag disposed inside the pillar interior member can deploy smoothly.

[0016] (3) In the wiring member assembly of (1) or (2), the interior member may include a main interior member and an additional interior member that covers the main interior member from the passenger compartment side, and at least a portion of the inner section may be located between the main interior member and the additional interior member.

[0017] In this case, at least a portion of the inner section is located between the main interior member and the additional interior member, and therefore the inner section can be more easily assembled to the interior member compared to when the entire inner section is disposed inside the main interior member.

[0018] (4) In the wiring member assembly of (3), the inner section may have an excess length absorbing portion that is bent so as to absorb excess length that is longer than the wiring path length, and the excess length absorbing portion may be covered by the main interior member.

[0019] This allows the bent excess length absorbing portion to be covered by the main interior member.

[0020] (5) In the wiring member assembly of (4), the main interior member may have an opening that opens to the passenger compartment side, and the inner section may pass through the opening and extend from a region between the main interior member and the additional interior member toward a region covered by the main interior member.

[0021] This makes it possible to easily place the inner section in the region between the main interior member and the additional interior member and in the region covered by the main interior member, by utilizing the opening in the main interior member.

[0022] (6) In the wiring member assembly of (5), the opening may be a recess that opens to a side edge of the main interior member.

[0023] This allows the inner section to be easily passed partway through the opening, making it possible to easily position the inner section in the region between the main interior member and the additional interior member and in the region covered by the main interior member.

[0024] (7) In any one of the wiring member assemblies (3) to (6), the additional interior member may be a film bonded to the surface of the main interior member in a state where the additional interior member is deformed along the surface of the main interior member.

[0025] In this case, the additional interior member is joined to the surface of the main interior member in a state in which it is deformed along the surface of the main interior member, and therefore the size of the additional interior member that protrudes from the surface of the main interior member toward the interior of the vehicle can be reduced, making it less likely to compress the interior space of the vehicle.

[0026] (8) In the wiring member assembly of (7), at least a portion of the inner section may be along a side edge of the main interior member.

[0027] This makes the wiring members less noticeable.

[0028] (9) In the wiring member assembly of any one of (1) to (8), the inner section may have a slack absorbing portion that is bent in a wavy, annular, or spiral shape.

[0029] This allows the interior member to move easily by extending the slack absorbing portion that is bent in a wavy, annular or spiral shape.

[0030] The additional wiring member assembly module of the present disclosure is as follows.

[0031] (10) An additional wiring member assembly module that is attached to a main interior member facing the passenger compartment, the additional interior member being attached to the main interior member so as to cover the main interior member, and a wiring member that is arranged along the main interior member so that at least a portion of the wiring member is located between the main interior member and the additional interior member, the additional wiring member assembly module including an excess length absorbing portion that is formed in a curved shape in the section of the wiring member that is covered by the main interior member or the additional interior member.

[0032] In this case, the additional wiring member can be easily assembled to the main interior member by attaching the additional interior member to the main interior member so as to cover the main interior member, and by arranging the wiring member along the interior member so that at least a portion of the wiring member is located between the main interior member and the additional interior member. In this case, since the wiring member includes a slack absorbing portion formed in a curved shape in the section covered by the main interior member or the additional interior member, when the airbag arranged inside the interior member deploys, the main interior member and the additional interior member can move so as to stretch the slack absorbing portion. Therefore, when the wiring member is held by the interior member including the main interior member and the additional interior member, the airbag arranged inside the interior member can deploy smoothly.

[0033] (11) In the additional wiring member assembly module of (10), the additional interior member may be a film that can be bonded to the surface of the main interior member in a state where it is deformed along the surface of the main interior member.

[0034] As a result, the additional interior member can be joined to the surface of the main interior member in a state in which it is deformed along the surface of the main interior member, so the size of the additional interior member that protrudes from the surface of the main interior member to the interior side can be reduced and it is less likely to compress the interior space of the vehicle.

[0035] [Details of the embodiments of the present disclosure] Specific examples of the wiring member assembly and additional wiring member assembly module 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.

[0036] [Embodiment 1] The wiring member assembly according to the first embodiment will be described below.

[0037] <Overall outline of the structure> Fig. 1 is a schematic perspective view showing a part of a vehicle 10 equipped with a wiring member assembly 20, and Fig. 2 is a schematic side view showing a part of the same vehicle. Fig. 3 is a schematic cross-sectional view taken along line III-III in Fig. 2.

[0038] The vehicle 10 is, for example, an automobile, and includes an instrument panel 12, pillars 14, and a roof 18.

[0039] The instrument panel 12 is located in front of the driver's seat and passenger seat. Instruments 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 movement 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 12c is provided facing rearward from the instrument panel 12.

[0040] The pillars 14 are parts that support the roof 18 relative to the vehicle body. The frontmost pillars, known as A-pillars, are shown in Figures 1 and 2. The lower end of the pillar 14 is located near the front corner of one side of the instrument panel 12. The upper end of the pillar 14 is located near the front corner of one side of the roof 18.

[0041] The pillar 14 includes a pillar body 15 formed of a rigid member such as metal, and an interior member 30 that covers the pillar body 15 from the passenger compartment side. The pillar body 15 is assumed to be part of the metal body.

[0042] The roof 18 is formed in a plate shape that covers the passenger compartment from above. The roof 18 has a multi-layer structure that includes a roof body made of a rigid member such as metal and a roof liner that covers the roof body from the passenger compartment side. The roof body is assumed to be part of the metal body.

[0043] In the vehicle 10, roof-side devices 19a and 19b are mounted on the roof 18, and the vehicle-side device 11 is mounted below the roof 18. The roof-side devices 19a and 19b are, for example, lamps, cameras, antennas, or sensors. The roof-side device 19a may be a standard electrical device in the vehicle. Standard equipment is equipment that is installed regardless of the grade of the vehicle and whether optional equipment is installed. The roof-side device 19b may be an additional electrical device that is added after the vehicle 10 is shipped from the vehicle manufacturing factory.

[0044] The vehicle-side device 11 is, for example, an ECU (electronic control unit), a power supply, an operation switch, or an audio device. The vehicle-side device 11 is disposed inside an instrument panel 12, for example.

[0045] A base wiring member 16 is attached to the pillar 14. The base wiring member 16 electrically connects the vehicle-side device 11 and the roof-side device 19a. In other words, the base wiring member 16 may be a wiring member that is provided as standard equipment. The base wiring member 16 may be disposed in the space between the pillar main body 15 and the interior member 30. Therefore, even if the interior member 30 is separated from the pillar main body 15, the base wiring member 16 can remain on the pillar main body 15.

[0046] The wiring member assembly 20 is also attached to the pillar 14. The wiring member assembly 20 includes a wiring member 38 for additional wiring. The wiring member 38 electrically connects the vehicle-side device 11 and the roof-side device 19b. In other words, the wiring member 38 may be a wiring member for adding equipment.

[0047] <About the wiring component assembly> The wiring member assembly 20 is assembled to the pillar body 15. The wiring member assembly 20 includes an interior member 30 and a wiring member .

[0048] The interior member 30 is a member facing the vehicle interior side. The interior member 30 is assumed to be exposed to the vehicle interior side and disposed in a position that can be observed by passengers inside the vehicle.

[0049] The wiring member 38 is held by the interior member 30 so as to extend along the interior member 30. The wiring member 38 extending along the interior member 30 means, for example, that if the interior member 30 is a flat member, the wiring member 38 extends along the direction in which the interior member 30 flattens. If the interior member 30 is an elongated member, the wiring member 38 may extend along the longitudinal direction of the interior member 30.

[0050] The wiring member 38 includes at least one electrical or optical transmission line. The electrical transmission line is, for example, a coated electric wire. The electric wire may be a signal line or a power line. The optical transmission line is, for example, an optical fiber. In this embodiment, the wiring member 38 includes at least one electric wire 39.

[0051] The wiring member 38 is held along a fixed path by the interior member 30. For this reason, when the interior member 30 moves away from the pillar main body 15, it is expected that the wiring member 38 will also move away from the pillar main body 15 together with the interior member 30.

[0052] Here, an airbag 80 may be stored between the pillar body 15 and the interior member 30. The airbag 80 passes between the pillar body 15 and the interior member 30 and deploys into the vehicle cabin. At this time, the interior member 30 is displaced entirely or partially by the inflation force of the airbag 80 so as to form a gap between the pillar body 15 and the interior member 30 through which the airbag 80 can pass. To enable smooth displacement of the interior member 30 when the airbag 80 deploys, the wiring member 38 is held in the interior member 30 in the following manner.

[0053] That is, the interior member 30 covers the pillar main body 15 from the passenger compartment side. The wiring member 38 is disposed along the interior member 30 and extends from the interior member 30 to be connected to the vehicle-side device 11 and the roof-side device 19b. Therefore, the wiring member 38 includes an inner section 42 covered by the interior member 30 and outer sections 44, 46 extending from the interior member 30. The inner section 42 is the section of the wiring member 38 that is covered by the interior member 30 so as not to be visible from inside the passenger compartment. The outer sections 44, 46 are the sections of the wiring member 38 that extend from the interior member 30. The outer sections 44, 46 may be covered by an interior member other than the interior member 30 and may not be visible from inside the passenger compartment. In this embodiment, the longitudinally intermediate portion of the wiring member 38 is the inner section 42, and both end portions of the wiring member 38 are the outer sections 44, 46.

[0054] In this embodiment, the outer sections 44, 46 include a first outer section 44 extending outward from the lower end of the interior member 30 and a second outer section 46 extending outward from the upper end of the interior member 30. The first outer section 44 extends outward from the lower end of the interior member 30 and is connected to the vehicle-side device 11. For example, the first outer section 44 is disposed along the outer surface of the instrument panel 12 or is guided inside the instrument panel 12 and extends toward the vehicle-side device 11. A connector at an end of the first outer section 44 is connected to the vehicle-side device 11. The second outer section 46 extends from the upper end of the interior member 30 to the outside of the interior member 30. The second outer section 46 extends between the roof main body and the roof liner of the roof 18. A connector at an end of the second outer section 46 is connected to a roof-side device 19b that is additionally equipped on the roof 18.

[0055] The inner section 42 is longer than the wiring path length of the wiring member 38 in the interior member 30. The wiring path of the wiring member 38 in the interior member 30 is a path connecting the lead-in and lead-out points of the wiring member 38 in the interior member 30 and the fixed points.

[0056] For example, in this embodiment, the interior member 30 is an elongated interior member for a pillar that covers the pillar main body 15 from the passenger compartment side. In the inner section 42, the wiring member 38 is held by the interior member 30 so as to run along the longitudinal direction of the interior member 30. The wiring path in the interior member 30 for a pillar runs along the longitudinal direction of the interior member 30. Therefore, the length of the wiring path in the interior member 30 is the length of the interior member 30. Therefore, the inner section 42 is longer than the interior member 30 for a pillar.

[0057] It is preferable that the inner section 42 be longer than the wiring path length of the wiring member 38 in the interior member 30, to the extent that a gap that allows the airbag 80 to deploy can be formed between the pillar body 15 and the interior member 30. For example, the inner section 42 is longer than the wiring path length by 5 cm or more, preferably 10 cm or more, and more preferably 15 cm or more.

[0058] The interior member 30 may include a main interior member 32 and an additional interior member 40 .

[0059] The main interior member 32 covers the pillar main body 15 from the passenger compartment side at a position closer to the pillar main body 15 than the additional interior member 40. The main interior member 32 is a member that covers the pillar main body 15 from the passenger compartment side, regardless of whether or not the added roof-side device 19b and wiring member 38 are present.

[0060] That is, the pillar main body 15 is, for example, a part of a metal body. The pillar main body 15 has an outer surface exposed outside the vehicle body. A metal reinforcing member 15r may be welded or the like to the passenger compartment side of the pillar main body 15 to support the roof 18. The main interior member 32 is a member formed from resin or the like. The main interior member 32 is formed, for example, in a semi-cylindrical shape. Both end portions of the main interior member 32 are disposed at positions corresponding to the upper and lower end portions of the pillar main body 15. The lower end of the main interior member 32 may be in contact with the instrument panel 12. The upper end of the main interior member 32 may be in contact with the roof liner of the roof 18. Both side edges of the main interior member 32 are disposed along both side edges of the pillar main body 15. The main interior member 32 is attached to the pillar main body 15 by, for example, a fitting structure. For example, a locking portion 33 having locking claws 33a protrudes from the inner side of the main interior member 32. Locking holes 15rh into which the locking portions 33 are fitted and locked are formed in the metal reinforcing member 15r. The main interior member 32 is attached to the pillar main body 15 by locking the locking portions 33 into the locking holes 15rh. The structure in which the main interior member 32 is attached to the pillar main body 15 is not limited to the above example. For example, the main interior member 32 may be attached to the pillar main body 15 by fitting both side edges of the main interior member 32 into grooves provided on both side edges of the pillar main body 15. Alternatively, the main interior member 32 may be attached to the pillar main body 15 by screws, adhesive, pressure-sensitive adhesive, etc.

[0061] The rear side edge of the main interior member 32 is preferably disposed so as to face the side edge of the pillar body 15 in an easily separable state. This allows the airbag 80 to pass between the pillar body 15 and the main interior member 32 and easily deploy into the passenger compartment.

[0062] With the main interior member 32 attached to the pillar main body 15, a space in which the base wiring member 16 can be arranged is formed between the pillar main body 15 and the main interior member 32. For example, the pillar main body 15 is formed in a semi-cylindrical shape, and the main interior member 32 is also formed in a semi-cylindrical shape. With the pillar main body 15 and the main interior member 32 combined together, an elongated space S1 in which the base wiring member 16 can be arranged is formed between them. The main interior member 32 is a member made of resin such as polypropylene, and has a degree of rigidity that allows it to maintain the space S1 in a constant shape.

[0063] A base wiring member 16 is disposed in the space S1. The base wiring member 16 extends along the pillar 14. Preferably, the base wiring member 16 is disposed at a position closer to the pillar body 15 than the main interior member 32. The base wiring member 16 may be fixed to the pillar body 15 by a clip or a clamp.

[0064] The airbag 80 is also disposed in the space S1. The base wiring member 16 is preferably disposed closer to the pillar body 15 than the airbag 80. If the base wiring member 16 is disposed on the pillar body 15 side, it is less likely to affect the deployment of the airbag 80. When the airbag 80 deploys, a force acts on the main interior member 32 in a direction away from the pillar body 15, and at least a portion of the main interior member 32 is displaced in a direction away from the pillar body 15. This forms a gap between the rear side edges of the pillar body 15 and the main interior member 32, through which the airbag 80 can pass when deploying toward the passenger compartment. At this time, the locked state of the locking portion 33 may be released, or the locked state may be maintained.

[0065] The additional interior member 40 is a member that covers the main interior member 32 from the passenger compartment side. The additional interior member 40 may be a member that is added to the main interior member 32 when the roof-side device 19b and the wiring member 38 are added. The additional interior member 40 may cover the entire main interior member 32 from the passenger compartment side, or may cover a portion of the main interior member 32 from the passenger compartment side. If the additional interior member extends over the same area as the main interior member, the entire edge around the additional interior member will follow the outer edge of the main interior member, making the additional interior member less noticeable. If at least a portion of the edge of the additional interior member follows at least a portion of the edge of the main interior member, the additional interior member will be less noticeable in that portion.

[0066] The wiring member 38 is held in the interior member 30 as follows. That is, the inner section 42 of the wiring member 38 is disposed on the surface of the main interior member 32 facing the passenger compartment. At least a portion of the inner section 42 is positioned between the main interior member 32 and the additional interior member 40. In this embodiment, the entire inner section 42 is positioned between the main interior member 32 and the additional interior member 40.

[0067] The entire portion of the wiring member 38 located on the main interior member 32 may be covered by the additional interior member 40, or a portion of the wiring member 38 located on the main interior member 32 may be exposed from the additional interior member 40.

[0068] The additional interior member 40 may be a film that is bonded to the surface of the main interior member 32 in a state where it is deformed along the surface of the main interior member 32 that faces the passenger compartment. In other words, the additional interior member 40 may be a film that has enough flexibility to be deformed along the surface of the main interior member 32 that faces the passenger compartment. The film may be any thickness, as long as it has flexibility that allows it to be deformed along the surface of the main interior member 32. The film may be made of resin, or may be a cloth with a combination of threads.

[0069] The additional interior member 40 may be adhered to the surface of the main interior member 32 by an adhesive layer 40g. The additional interior member 40 may be joined to the surface of the main interior member 32 by adhesive, welding, or hook-and-loop fasteners. The additional interior member 40 may be arranged along the surface of the main interior member 32 by other hook structures, clips, or nails.

[0070] The wiring member 38 is held along the surface of the main interior member 32 by being sandwiched between the surface of the main interior member 32 and the additional interior member 40. For example, the surface of the main interior member 32 and the additional interior member 40 are adhered to each other on both sides of the wiring member 38 arranged along the main interior member 32, so that the wiring member 38 is held in a fixed path along the surface of the main interior member 32. The wiring member 38 may be held in a fixed position by the main interior member or the additional interior member. For example, the wiring member 38 may be welded or glued to the main interior member or the additional interior member.

[0071] If the additional interior member 40 is a film, then by cutting a general-purpose film to fit the surface shape of the main interior member 32, it is possible to easily process the additional interior member 40 appropriate for covering the main interior member 32. Furthermore, if the additional interior member 40 is a film, then the additional interior member 40 can be easily deformed to fit the curved surface shape of the main interior member 32. Furthermore, if the additional interior member 40 is a film, then rattle noise is less likely to occur between the main interior member 32 and the additional interior member 40.

[0072] The surface color of the additional interior member 40 may be a color of the same family as the surface color of the main interior member 32. For example, if colors are divided into 13 families 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 family may be considered to be colors of the same family.

[0073] The surface design texture of the additional interior member 40 may be the same as the surface design texture of the main interior member 32. 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 main interior member 32 has a wood grain pattern, marble pattern, grain pattern, matte pattern, glossy surface, or metallic surface, the surface of the additional interior member 40 should preferably have the same pattern or texture as the surface of the instrument panel 12.

[0074] At least a portion of the inner section 42 of the wiring member 38 may be along the side edge of the main interior member 32. For example, at least a portion of the inner section 42 may be disposed within a range of 5 cm, preferably within a range of 4 cm, more preferably within a range of 3 cm, and more preferably within a range of 2 cm from the side edge of the main interior member 32.

[0075] If the additional interior member 40 is a film, the portion of the additional interior member 40 that covers the wiring member 38 will protrude linearly. If at least a portion of the wiring member 38 is along the side edge of the main interior member 32, the linear protrusion of the wiring member 38 will be less noticeable.

[0076] It is not essential that the additional interior member 40 be a film. The additional interior member 40 may be a member having rigidity that can maintain a space between the additional interior member 40 and the main interior member so that the wiring member 38 can be arranged therein. For example, the additional interior member 40 may be a molded resin product.

[0077] As described above, the inner section 42 is longer than the wiring path length of the wiring member in the interior member 30. In other words, the inner section 42 has an excess length that exceeds the length necessary for disposing the wiring member along the interior member 30. The inner section 42 has an excess length absorbing portion 43 that absorbs the excess length. For example, the excess length absorbing portion 43 is formed by setting a part of the inner section 42 so as to take a detour around the shortest wiring path.

[0078] In this embodiment, the slack absorbing portion 43 is a portion of the inner section 42 whose path is set so that part of it describes a loop. Under normal conditions, the slack absorbing portion 43 is disposed between the main interior member 32 and the additional interior member 40, thereby maintaining a state along the path that absorbs the slack. When the wiring member 38 is pulled so as to come out of the interior member 30, the slack absorbing portion 43 penetrates into the adhesive layer portion between the main interior member 32 and the additional interior member 40, and peels the additional interior member 40 from the main interior member 32. This causes the slack absorbing portion 43 to deform into a nearly straight state, allowing the slack to be pulled out from the interior member 30. The pulled-out slack allows the interior member 30 to be partially or entirely displaced in a direction away from the pillar main body 15.

[0079] <Example of assembly work for wiring component assembly> FIG. 4 is an explanatory diagram showing an example of an assembly operation for the wiring member assembly 20. As shown in FIG.

[0080] It is assumed that the vehicle 10 is equipped with the vehicle-side device 11 and the roof-side device 19a, and that the vehicle-side device 11 and the roof-side device 19a are electrically connected by the base wiring member 16.

[0081] Consider a case where a roof-side device 19b is added to this vehicle 10. An additional wiring member assembly module 20B attached to the main interior member 32 includes a wiring member 38 for electrically connecting the vehicle-side device 11 and the roof-side device 19b.

[0082] The additional wiring member assembly module 20B is a combined part combining the above-mentioned additional interior member 40 and the wiring member 38. The additional wiring member assembly module 20B may be provided in a state in which the wiring member 38 is adhered to the additional interior member 40 by an adhesive layer, or may be provided in a state in which the additional interior member 40 and the wiring member 38 are separate but packaged together. In the latter case, it is preferable that a path including a location where an extra length of the wiring member 38 is set is drawn on the additional interior member 40.

[0083] The additional interior member 40 is attached to the main interior member 32 so that at least a part of the wiring member 38 is positioned between the main interior member 32 and the additional interior member 40 and is arranged along the main interior member 32. For example, the adhesive layer 40g of the additional interior member 40 is adhered to the surface of the main interior member 32.

[0084] In this case, the section of the wiring member 38 between the main interior member 32 and the additional interior member 40 is set so as to include an excess length absorbing portion 43 formed in a curved shape. For example, the wiring member 38 may be adhered to the additional interior member 40 so as to form the excess length absorbing portion 43. Also, for example, when sandwiching the wiring member 38 between the main interior member 32 and the additional interior member 40, the wiring member 38 may be partially bent to form the excess length absorbing portion 43. As will be shown in a second embodiment later, the excess length absorbing portion may be formed closer to the pillar body 15 than the main interior member.

[0085] Then, when, before, or after the additional wiring member assembly module 20B is installed, the connectors at the ends of the wiring member 38 are connected to the vehicle-side device 11 and the roof-side device 19b. As a result, the wiring member 38, which electrically connects the vehicle-side device 11 and the roof-side device 19b, is arranged along the pillar 14.

[0086] When arranging the wiring member 38, it is not necessary to remove the main interior member 32 from the pillar body 15, so the work of arranging the wiring member 38 along the pillar 14 can be easily performed.

[0087] <Airbag deployment> An example of the deployment operation of the airbag 80 will be described. As shown in FIGS. 5 and 6 , when the airbag 80 deploys, the portion of the interior member 30 that covered the airbag 80 is pushed away from the pillar main body 15, i.e., toward the vehicle cabin. The outer sections 44, 46 of the wiring member 38 are connected to the vehicle-side device 11 and the roof-side device 19b, and it is assumed that an intermediate portion of the wiring member 38 is also supported by the vehicle. Therefore, while the outer sections 44, 46 of the wiring member 38 are held in a fixed position relative to the vehicle 10, the interior member 30 attempts to move away from the pillar main body 15, and a force acts on the outer sections 44, 46 to pull them outward from the end of the interior member 30. This pulls the slack absorbing section 43, reducing the annular shape, and the inner section 42 is pulled out of the interior member 30. The interior member 30 can be displaced away from the pillar main body 15 by the amount of the slack in the inner section 42 pulled out of the interior member 30.

[0088] As a result, a gap through which the airbag 80 can slip out is formed between the rear side edges of the pillar main body 15 and the interior member 30. The locking portion 33 may slip out of the locking hole 15rh to form the gap, or the interior member 30 may partially deform while the locking portion 33 remains locked in the locking hole 15rh to form the gap.

[0089] The airbag 80 can be smoothly deployed into the interior of the vehicle by passing between the rear side edges of the pillar body 15 and the interior member 30.

[0090] <Effects, etc.> According to the wiring member assembly 20 and additional wiring member assembly module 20B configured as described above, the inner section 42 of the wiring member 38 is longer than the wiring path length of the wiring member 38 in the interior member 30. Therefore, when the airbag 80 arranged inside the interior member 30 deploys, part of the inner section 42 is pulled out from the interior member 30, allowing the interior member 30 to move entirely or partially. Therefore, when the wiring member 38 is held by the interior member 30, the airbag 80 arranged inside the interior member 30 can deploy smoothly.

[0091] The wiring member 38 also includes an inner section 42 and outer sections 44, 46. The first outer section 44 and the second outer section 46 extending from one end and the other end of the pillar interior member 30 can be used to electrically connect the roof-side equipment 19b of the vehicle 10 to the vehicle-side equipment 11 below the roof 18. When the airbag 80 arranged inside the interior member 30 deploys, part of the inner section 42 is pulled out from one end or the other end of the interior member 30, thereby moving part or all of the interior member 30. Therefore, when the wiring member 38 is held by the pillar interior member 30, the airbag 80 arranged inside the interior member 30 can deploy smoothly.

[0092] Furthermore, in order to arrange the wiring member 38 along the pillar 14, it is conceivable, for example, to remove the entire longitudinal direction of the main interior member 32 from the pillar body 15 and arrange the entire inner section 42 inside the main interior member 32. In this embodiment, the interior member 30 includes the main interior member 32 and the additional interior member 40, and at least a portion of the inner section 42 is located between the main interior member 32 and the additional interior member 40. For this reason, it is not necessary to separate the entire longitudinal direction of the main interior member 32 from the pillar body 15, and the inner section 42 can be easily assembled to the interior member.

[0093] Furthermore, since the additional interior member 40 is joined to the surface of the main interior member 32 in a state in which it is deformed along the surface of the main interior member 32, the size of the additional interior member 40 that protrudes from the surface of the main interior member 32 toward the interior of the vehicle can be reduced, and it is less likely to compress the interior space of the vehicle.

[0094] Furthermore, if at least a portion of the inner section 42 is along the side edge of the main interior member 32, the portion of the inner section 42 will be observed to blend in with the side edge, making the wiring member 38 less noticeable.

[0095] Furthermore, because the inner section 42 has the annular slack absorbing portion 43, the inner section 42 is pulled out of the interior member 30 by extending the slack absorbing portion 43 so as to eliminate the annular shape. This allows the interior member 30 to move easily. Compared to when slack is set in the entire inner section 42, the slack setting point can be set at a fixed position, so the pulling behavior of the wiring member 38 is stable.

[0096] It is not essential that the slack absorbing portion 43 is annular. For example, as shown in Fig. 7, the slack absorbing portion 43B may be a portion where a part of the inner section 42 is bent in a wavy shape. In this case, the slack absorbing portion 43B is deformed so as to approach a straight state, allowing the inner section 42 to protrude from the interior member 30.

[0097] [Embodiment 2] A wiring member assembly 120 according to embodiment 2 will be described. Fig. 8 is a schematic side view showing the wiring member assembly 120 according to embodiment 2. Fig. 9 is a cross-sectional view taken along line IX-IX in Fig. 8. In the description of embodiment 2, components similar to those described in embodiment 1 are denoted by the same reference numerals, and description thereof will be omitted. In Fig. 8 and subsequent figures, the airbag 80 is omitted.

[0098] The wiring member 38 of the wiring member assembly 120 has a slack absorbing portion 143 that corresponds to the above-mentioned slack absorbing portion 43. The slack absorbing portion 143 is covered by the main interior member 32 and is located in the space S1 between the main interior member 32 and the pillar body 15. Because the space S1 of a certain size is formed by the rigidity of the main interior member 32 and the pillar body 15, it is possible to avoid restricting the slack absorbing portion 143 as much as possible. For this reason, the slack absorbing portion 143 can easily deform so as to pull out the slack to the outside. Furthermore, by arranging the slack absorbing portion 143 where the wiring member 38 is bent inside the main interior member 32, the slack absorbing portion 143 becomes less noticeable.

[0099] More specifically, the main interior member 32 has an opening 32a that opens to the passenger compartment side. The opening 32a opens on both sides of the main interior member 32. That is, the opening 32a opens to the space S1 side and the additional interior member 40 side.

[0100] In this embodiment, the opening 32a is also a recess that opens into the side edge of the main interior member 32. For example, the opening 32a may be an opening formed so as to recess in a U-shape or semicircular shape inward from the side edge of the main interior member 32. The opening 32a is preferably larger than the vertical cross section of the wiring member 38 so that the wiring member 38 can freely pass through the opening 32a.

[0101] The inner section 42 of the wiring member 38 passes through the opening 32a from the region between the main interior member 32 and the additional interior member 40 toward the region covered by the main interior member 32. Then, an excess length absorbing portion 143 is provided in the portion of the wiring member 38 covered by the main interior member 32.

[0102] In this embodiment, the main interior member 32 has two openings 32a. Outside the two openings 32a in the longitudinal direction of the main interior member 32, the wiring member 38 is located between the main interior member 32 and the additional interior member 40. Between the main interior member 32 and the additional interior member 40, the wiring member 38 may be arranged along the side edge of the main interior member 32.

[0103] Between the two openings 32a in the longitudinal direction of the main interior member 32, the wiring member 38 is covered by the main interior member 32, and is located in the space S1 between the main interior member 32 and the pillar main body 15. In the space S1, the wiring member 38 is bent to form an excess length absorbing portion 143. For example, in the space S1, the wiring member 38 is bent so as to form a wavy shape to form the excess length absorbing portion 143. It is preferable that the wiring member 38 is formed into a shape that forms the excess length absorbing portion 143.

[0104] It is not essential that the slack absorbing portion 143 be wavy. For example, as shown in Fig. 10, the wiring member 38 may be bent into a ring shape to form the slack absorbing portion 143B. Alternatively, as shown in Fig. 11, the wiring member 38 may be bent into a spiral to form the slack absorbing portion 143C. The spiral may be a three-dimensional spiral formed on the circumferential surface of a cylinder, or a planar spiral.

[0105] The wiring member assembly 120 configured as described above has the following advantages in addition to the advantages of the first embodiment. That is, the bent slack absorbing portion 143 can be covered by the main interior member 32. This reduces the constraint on the slack absorbing portion 143, allowing the slack absorbing portion 143 to easily deform so as to pull out the slack to the outside. Furthermore, the slack absorbing portion 143 is less noticeable from the passenger compartment.

[0106] Even if the slack absorbing portion 143 is disposed inside the main interior member 32, other portions of the inner section 42 can be disposed outside the main interior member 32. For this reason, the work of disposing the inner section 42 relative to the pillar 14 is easier than if the entire inner section 42 were disposed inside the main interior member 32.

[0107] In addition, since the opening 32a is formed in the wiring member 38, the opening 32a of the main interior member 32 can be used to easily position the inner section 42 in the area between the main interior member 32 and the additional interior member 40 and in the area covered by the main interior member 32.

[0108] In a state before the wiring member 38 is placed on the pillar 14, the opening 32a may be formed in the main interior member 32, or the opening 32a may be closed. If the opening 32a is closed, it is preferable that a planned break line that is easy to break, such as a thin-walled portion, be formed in the area of ​​the main interior member 32 where the opening 32a is to be formed.

[0109] Furthermore, if the opening 32a is a recess that opens into the side edge of the main interior member 32, the intermediate portion in the longitudinal direction of the wiring member 38 can be easily passed through the opening 32a from the outside of the side edge of the main interior member 32. Therefore, the inner section 42 can be easily disposed in the region between the main interior member 32 and the additional interior member 40 and in the region covered by the main interior member 32.

[0110] Furthermore, if the slack absorbing portions 143, 143B, 143C are bent in a wavy, circular, or spiral shape, the interior member 30 can be easily moved by extending the slack absorbing portions 143, 143B, 143C.

[0111] When the slack absorbing portions 143, 143B, 143C are formed into a shape that can absorb slack, the positions of the slack absorbing portions 143, 143B, 143C in the space S1 are stable, and the behavior of the wiring member 38 being pulled out from the slack absorbing portions 143, 143B, 143C is stable.

[0112] It is not essential that the opening 32a formed in the main interior member 32 has a shape that opens to the edge of the main interior member 32. For example, the opening may be a hole formed so as to be surrounded at a position away from the edge of the main interior member. In this case, the wiring member can be passed through the hole and placed in a position covered by the main interior member.

[0113] In this embodiment, the additional interior member 40 may be omitted between the openings 32a, and the entire additional interior member 40 may be omitted.

[0114] [Variations] In the above-described embodiments, the interior member is an interior member for a pillar. However, the interior member may be another interior member. For example, the interior member that holds the wiring member may be an interior member that covers a passenger airbag in front of the passenger seat.

[0115] In the above-described embodiments, the wiring member assembly holds wiring members for addition. However, the wiring member assembly may hold wiring members for standard equipment that are not for addition, and the wiring members for the standard equipment may have slack absorbing portions.

[0116] It is not essential that the interior member 30 include the main interior member 32 and the additional interior member 40. For example, even when the wiring member 38 is held by one interior member corresponding to the main interior member 32, it is preferable that the length of the inner section 42 of the wiring member 38 be longer than the wiring path length in the interior member.

[0117] The configurations described in the above embodiments and modifications can be combined as appropriate as long as they are not mutually contradictory. [Explanation of symbols]
