[0001] The present disclosure relates to a wiring member assembly and an additional wiring member assembly module.
[0002] Patent document 1 discloses that equipment mounted on the roof of a vehicle and equipment mounted below the roof are electrically connected via a relay transmission member, and that the relay connection portion is arranged along the pillar.
[0003] International Publication No. 2021 / 220573
[0004] It is assumed that the wiring member is held by an interior member such as a pillar. Also, an airbag may be disposed inside the interior member. Even in such a case, it is desirable for the airbag to be able to deploy smoothly.
[0005] Therefore, an object of the present disclosure is to enable an airbag arranged inside an interior member to be smoothly deployed when a wiring member is held by the interior member.
[0006] The wiring member assembly of the present disclosure includes a first interior member facing the vehicle interior, a second interior member located adjacent to the first interior member, and a wiring member held by the first interior member so as to run along the first interior member, the wiring member including a first section covered by the first interior member and a second section covered by the second interior member, the second section having an excess length absorbing portion that is bent to absorb excess length that allows for displacement of the first interior member relative to the second interior member.
[0007] The additional wiring member assembly module of the present disclosure is an additional wiring member assembly module that is attached to a main interior member facing the passenger compartment, and is equipped with an additional interior member that is attached to the main interior member so as to cover the main interior member, and a wiring member that includes a first section that is arranged along the additional interior member and a second section that extends from the additional interior member, wherein the second section is formed into a curved shape and has an extensible slack absorbing section.
[0008] According to the present disclosure, when the wiring member is held by the interior member, the airbag arranged inside the interior member can be smoothly deployed.

[0010] [Description of 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 a first interior member facing the passenger compartment, a second interior member positioned adjacent to the first interior member, and a wiring member held by the first interior member so as to run along the first interior member, wherein the wiring member includes a first section covered by the first interior member and a second section covered by the second interior member, and the second section has an excess length absorbing portion that is bent to absorb excess length that allows for displacement of the first interior member relative to the second interior member.
[0013] According to the present disclosure, the second section of the wiring member has an excess length absorbing portion that is bent to absorb excess length to allow for displacement of the first interior member relative to the second interior member. Therefore, when an airbag arranged inside the first interior member deploys, part of the second section is pulled out from the second interior member, allowing the first interior member to displace relative to the second interior member. Therefore, when the wiring member is held by the first interior member, the airbag arranged inside the first interior member can deploy smoothly.
[0014] (2) In the wiring member assembly of (1), the first interior member may be an elongated interior member for a pillar that covers the pillar main body from the passenger compartment side, the wiring member may be held by the interior member for a pillar so that the first section is aligned in the longitudinal direction of the interior member for a pillar, and the excess length absorbing portion may be located next to a boundary between the first interior member and the second interior member.
[0015] As a result, by extending the excess length absorbing portion located next to the boundary, the second section can be smoothly pulled out from the second interior member, and the first interior member can be smoothly displaced.
[0016] (3) In the wiring member assembly of (2), the second interior member may be a roof interior member.
[0017] The wiring member held in the pillar interior member is suitable as additional wiring for roof-side equipment to be added to the roof. When adding the roof-side equipment, it is expected that at least a portion of the roof interior member will be separated from the roof main body. Therefore, the slack absorbing portion can be easily arranged within the roof interior member as the second interior member.
[0018] (4) In the wiring member assembly of any one of (1) to (3), the first 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 first section may be located between the main interior member and the additional interior member.
[0019] In this case, at least a portion of the first section is located between the main interior member and the additional interior member, so the first section can be more easily assembled to the interior member compared to when the entire first section is disposed inside the main interior member.
[0020] (5) In the wiring member assembly of (4), the wiring member may extend from the outside of the main interior member through the boundary between the main interior member and the second interior member to the inside of the second interior member.
[0021] This allows the first section of the wiring member to be disposed outside the main interior member, and the second section of the wiring member to be disposed inside the second interior member.
[0022] (6) In the wiring member assembly of (5), a recess through which the wiring member passes may be formed in an edge portion of the main interior member on the second interior member side or an edge portion of the second interior member on the main interior member side.
[0023] This makes it difficult for unnecessary force to be applied to the wiring member at the boundary between the main interior member and the second interior member.
[0024] (7) In the wiring member assembly according to any one of (4) to (5), 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 first 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 excess length absorbing portion may be a portion of the second section bent in a wavy, circular, or spiral shape.
[0029] In this case, the first interior member can be easily displaced by extending the excess length 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 wiring member assembly module comprising: an additional interior member that is attached to the main interior member so as to cover the main interior member; a wiring member that includes a first section that is arranged along the additional interior member; and a second section that extends from the additional interior member, wherein the second section is formed into a curved shape and has an extensible excess length absorbing portion.
[0032] According to the present disclosure, the second section of the wiring member has a bent shape and an extensible slack absorbing section. Therefore, when an airbag arranged inside the main interior member deploys, the main interior member can be easily displaced by stretching the slack absorbing section of the second section. Therefore, when the wiring member is held by the main interior member and the additional interior member, the airbag arranged inside the main interior member can be smoothly deployed.
[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] This allows the additional interior member to be joined to the surface of the main interior member in a state where it is deformed along the surface of the main interior member. This reduces the size of the additional interior member that protrudes from the surface of the main interior member into the cabin, making it 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] Fig. 1 is a schematic perspective view showing a part of a vehicle 10 equipped with a wiring member assembly 20, Fig. 2 is a schematic side view showing a part of the same vehicle, and Fig. 3 is a schematic cross-sectional view taken along line III-III in Fig. 2.
[0037] The vehicle 10 is, for example, an automobile, and includes an instrument panel 12, pillars 14, and a roof 18.
[0038] 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.
[0039] The pillars 14 are parts that support the roof 18 relative to the vehicle body. The frontmost pillar, known as the A-pillar, is 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.
[0040] The pillar 14 includes a pillar body 15 formed from a rigid member such as metal, and an interior member 30 that covers the pillar body 15 from the vehicle interior side. The pillar body 15 is assumed to be part of the metal body. The interior member 30 is formed from a resin or the like. The interior member 30 is an example of a first interior member that faces the vehicle interior side, and is an example of an elongated pillar interior member that covers the pillar body 15 from the vehicle interior side.
[0041] 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 main body 18a formed of a rigid member such as metal, and a roof liner 19 that covers the roof main body from the passenger compartment side. The roof main body is assumed to be part of the metal body.
[0042] The roof liner 19 is made of resin or the like and has a flat shape that spreads downward below the roof main body 18a. The outer portion of the roof liner 19 in the vehicle width direction curves downward and faces the upper edge of the opening of the door D. The front end of the outer portion of the roof liner 19 in the vehicle width direction faces the upper end of the pillar 14 and faces the interior member 30. Therefore, the roof liner 19 is located next to the interior member 30. For example, the roof liner 19 may be located next to the interior member 30 and in contact with the interior member 30. The roof liner 19 is an example of a second interior member located next to the first interior member, and is an example of an interior member for the roof.
[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, for example, disposed inside an instrument panel 12.
[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 body 15 and the interior member 30. Therefore, even if the interior member 30 is separated from the pillar body 15, the base wiring member 16 can remain on the pillar 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] <Regarding the Wiring Member Assembly> The wiring member assembly 20 is assembled to the pillar main body 15. The wiring member assembly 20 includes an interior member 30 and a wiring member 38. The wiring member assembly 20 includes the interior member 30 as a first interior member, the roof liner 19 as a second interior member, and the wiring member 38.
[0048] The interior member 30 faces the vehicle interior side. The interior member 30 is exposed to the vehicle interior side and is assumed to be 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 in the case where the interior member 30 is a flat member, the wiring member 38 extends along the direction in which the interior member 30 extends flat. In the case where 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. The interior member 30 covers the pillar body 15 from the passenger compartment side. The wiring member 38 is arranged 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 a first section 42 covered by the interior member 30 and outer sections 44, 46 extending from the interior member 30. The first section 42 is a 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 first section 42 may extend linearly along the longitudinal direction of the interior member 30, or may be curved along the way.
[0052] The interior member 30 may include a main interior member 32 and an additional interior member 40 .
[0053] The main interior member 32 covers the pillar body 15 from the passenger compartment side at a position closer to the pillar body 15 than the additional interior member 40. The main interior member 32 is a member that covers the pillar body 15 from the passenger compartment side, regardless of whether or not the roof-side device 19b and wiring member 38 are added.
[0054] 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 of 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 surface 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.
[0055] 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.
[0056] With the main interior member 32 attached to the pillar body 15, a space in which the base wiring member 16 can be arranged is formed between the pillar body 15 and the main interior member 32. For example, the pillar 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 body 15 and the main interior member 32 combined, 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.
[0057] 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.
[0058] An airbag 80 may be stored in the space S1 between the pillar body 15 and the interior member 30. 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 closer to the pillar body 15, 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.
[0059] 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.
[0060] The wiring member 38 is held in the interior member 30 as follows. That is, the first 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 first section 42 is located between the main interior member 32 and the additional interior member 40. In this embodiment, the entire first section 42 is located between the main interior member 32 and the additional interior member 40.
[0061] 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 portion of the wiring member 38 located on the main interior member 32 may be exposed from the additional interior member 40.
[0062] 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 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.
[0063] 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.
[0064] 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. In this embodiment, the wiring member 38 is held by the interior member 30 so that the first section 42 is along the longitudinal direction of the interior member 30. 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.
[0065] 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.
[0066] 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, including achromatic white, gray, and black, and chromatic red, yellow-red, yellow, yellow-green, green, blue-green, blue, blue-purple, purple, and red-purple, in accordance with JIS Z 8102:2001, colors belonging to the same family may be considered to be colors of the same family.
[0067] 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.
[0068] At least a portion of the first 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 first section 42 may be disposed at a position within 5 cm, preferably within 4 cm, more preferably within 3 cm, and even more preferably within 2 cm from the side edge of the main interior member 32.
[0069] 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.
[0070] 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 in which the wiring member 38 can be arranged. For example, the additional interior member 40 may be a molded resin product.
[0071] As described above, the wiring member 38 is held along a fixed path by the interior member 30. Therefore, when the interior member 30 separates from the pillar body 15, it is expected that the wiring member 38 will also separate from the pillar body 15 together with the interior member 30. It is also considered that the airbag 80 is disposed in the space S1 between the pillar body 15 and the interior member 30. The airbag 80 deploys into the vehicle cabin by passing between the pillar body 15 and the interior member 30. 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, an excess length absorbing portion 43 is provided in the portion of the wiring member 38 that is covered by the roof liner 19.
[0072] That is, the outer sections 44, 46 of the wiring member 38 are sections of the wiring member 38 that extend beyond the interior member 30. In the present embodiment, the longitudinal intermediate portion of the wiring member 38 is the first section 42, and both end side portions of the wiring member 38 are the outer sections 44, 46.
[0073] The outer sections 44, 46 may be covered by an interior member other than the interior member 30 and may not be visible from within the vehicle cabin. In this embodiment, the outer section 44 extends outward from the lower end of the interior member 30 and is connected to the vehicle-side equipment 11. The outer section 44 may be covered entirely or partially by another interior member. For example, the outer section 44 may be disposed along the outer surface of the instrument panel 12 or may be guided inside the instrument panel 12 and extend toward the vehicle-side equipment 11. The outer section 46 extends outward from the upper end of the interior member 30 and extends between the roof main body 18a and the roof liner 19. The outer section 46 passes between the roof main body 18a and the roof liner 19 and is connected via a connector to roof-side equipment 19b that is additionally equipped on the roof 18. The outer section 46 is an example of a second section 46 covered by the roof liner 19 as a second interior member.
[0074] The second section 46 has an excess length absorbing portion 43. The excess length absorbing portion 43 is a curved portion of the second section so as to absorb excess length that allows displacement of the interior member 30 relative to the roof liner 19.
[0075] The slack absorbing portion 43 may be located anywhere inside the roof liner 19, as long as it is positioned so that the slack can be pulled out from the roof liner 19. The slack absorbing portion 43 may be located next to the boundary between the interior member 30 and the roof liner 19. More specifically, the slack absorbing portion 43 may be located next to the boundary between the upper end of the interior member 30 and the front end of the roof liner 19 on the outer side in the vehicle width direction. In this case, the slack absorbing portion 43 may be located within 15 cm, 10 cm, or 5 cm of the boundary. Between the slack absorbing portion 43 and the boundary, the wiring member 38 is not constrained by the vehicle body, such as the roof main body 18a, or by the interior member, such as the roof liner 19. Therefore, the slack formed by the extension of the slack absorbing portion 43 can be easily pulled out toward the boundary. Between the slack absorbing portion 43 and the boundary, the wiring member 38 preferably extends straight without bending. For example, the extra length is 5 cm or more longer than the wiring path length, preferably 10 cm or more longer, and more preferably 15 cm or more longer.
[0076] In this embodiment, the slack absorbing portion 43 is a portion of the first section 42 that is routed so that a portion of the first section 42 forms a loop. Under normal conditions, the slack absorbing portion 43 is disposed in the space between the roof main body 18a and the roof liner 19. When the first section 42 is pulled due to displacement of the interior member 30 relative to the roof liner 19, the second section 46 is pulled so as to extend out of the roof liner 19. This causes the slack absorbing portion 43 to deform into a nearly straight state, allowing the slack portion to extend out of the roof liner 19. The slack portion 43 can partially or entirely displace the interior member 30 in a direction away from the pillar main body 15 and the roof liner 19 by the pulled-out slack portion.
[0077] The first section 42 is located outside the main interior member 32, and the second section 46 is located inside the roof liner 19. The wiring member 38 extends from the outside of the main interior member 32, through the boundary between the main interior member 32 and the roof liner 19, and to the inside of the roof liner 19. This realizes a configuration in which a portion of the wiring member 38 is located outside the main interior member 32, and the slack absorbing portion 43 is located inside the roof liner 19.
[0078] <Example of assembly work of wiring member assembly> FIG. 4 is an explanatory diagram showing an example of assembly work of the wiring member assembly 20. As shown in FIG.
[0079] It is assumed that the vehicle 10 is equipped with the vehicle-side device 11 and the roof-side device 19 a, and the vehicle-side device 11 and the roof-side device 19 a are electrically connected by the base wiring member 16 .
[0080] 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.
[0081] The additional wiring member assembly module 20B is a combined part in which the above-mentioned additional interior member 40 and the wiring member 38 are combined. 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 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 excess length of the wiring member 38 is set is drawn on the additional interior member 40. A second section 46 of the wiring member 38 is a portion that extends from the additional interior member 40. The second section 46 has an excess length absorbing portion 43. The excess length absorbing portion 43 is formed into a curved shape and is stretchable to remove the curve.
[0082] 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.
[0083] At this time, the first section 42 is sandwiched between the main interior member 32 and the additional interior member 40. As a result, the first section 42 is held by the wiring member 38 in a state along a fixed path.
[0084] During, before, or after installation of the additional wiring member assembly module 20B, the roof liner 19 is wholly or partially removed from the roof main body 18a, and the second section 46 is disposed between the roof main body 18a and the roof liner 19. The excess length absorber 43 is also disposed between the roof main body 18a and the roof liner 19. In addition, a connector at the end of the second section 46 is connected to the roof-side device 19b.
[0085] In addition, the outer section 44 extending below the pillar 14 is also pulled out toward the vehicle-side device 11, and a connector at the end of the outer section 44 is connected to the vehicle-side device 11. As a result, the wiring member 38 that 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 Operation> An example of the deployment operation of the airbag 80 will be described. As shown in Figures 5 and 6 , when the airbag 80 deploys, the portion of the interior member 30 that covered the airbag 80 is pushed in a direction away from the pillar body 15, i.e., toward the vehicle interior. With the first section 42 of the wiring member 38 held by the interior member 30, the interior member 30 attempts to move in a direction away from the pillar body 15, and a force acts on the second section 46 to pull it outward from the roof liner 19. This pulls the excess length absorbing portion 43, reducing the annular shape and causing the second section 46 to be pulled outward from the roof liner 19. The interior member 30 can be displaced in a direction away from the pillar body 15 and the roof liner 19 by the excess length of the second section 46 pulled outward from the roof liner 19.
[0088] Since the slack absorbing portion 43 is located inside the roof liner 19, it is difficult for the slack absorbing portion 43 to come into contact with human hands, etc., and the slack absorbing state is stable.
[0089] 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. Note that 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.
[0090] The airbag 80 can be smoothly deployed into the passenger compartment by passing between the rear side edges of the pillar body 15 and the interior member 30 .
[0091] <Effects, etc.> According to the wiring member assembly 20 and additional wiring member assembly module 20B configured as described above, the second section 46 of the wiring member 38 has an excess length absorbing portion 43 that is bent to absorb excess length that allows for displacement of the interior member 30 relative to the roof liner 19. Therefore, when the airbag 80 arranged inside the interior member 30 deploys, part of the second section 46 is pulled out from the roof liner 19, allowing the interior member 30 to displace relative to the roof liner 19. 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.
[0092] Furthermore, the first interior member is an interior member 30 for a pillar 14, and the slack absorbing portion 43 is located next to the boundary between the interior member 30 and the roof liner 19. Therefore, when the interior member 30 is displaced due to the deployment of an airbag 80 arranged inside the interior member 30, the slack absorbing portion 43 next to the boundary stretches, effectively pulling out the slack of the second section 46. As a result, when the wiring member 38 is held by the interior member 30 for a pillar, the airbag 80 arranged inside the interior member 30 can be smoothly deployed.
[0093] The second interior member is the roof liner 19. The wiring member 38 held in the interior member 30 for the pillar 14 is suitable as additional wiring for roof-side equipment 19b to be added to the roof 18. When the roof-side equipment 19b is added, it is expected that at least a portion of the roof liner 19 will be separated from the roof main body 18a. Therefore, the excess length absorbing portion 43 can be easily disposed inside the roof liner 19.
[0094] 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 first section 42 inside the main interior member 32. In the present embodiment, the interior member 30 includes the main interior member 32 and the additional interior member 40, and at least a portion of the first 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 first section 42 can be easily assembled to the interior member.
[0095] In addition, since the wiring member 38 passes through the boundary between the main interior member 32 and the roof liner 19, the first section 42 of the wiring member 38 can be disposed outside the main interior member 32, and the second section 46 of the wiring member 38 can be easily disposed inside the roof liner 19.
[0096] 7 , a recess 32g or a recess 19g through which the wiring member 38 passes may be formed in the edge of the main interior member 32 on the roof liner 19 side or the edge of the roof liner 19 on the main interior member 32 side. The recess 32g or the recess 19g has a shape that recesses inward from the edge of the main interior member 32 or the roof liner 19. The recess 32g or the recess 19g may be semicircular, semielliptical, rectangular, or triangular. It is preferable that the recess 32g or the recess 19g is larger than the cross-sectional shape of the wiring member 38 so that the wiring member 38 can pass through the recess 32g or the recess 19g without being strongly pressed against the edge of the recess 32g or the recess 19g.
[0097] This makes it difficult for unnecessary force to be applied to the wiring member 38 at the boundary between the main interior member 32 and the roof liner 19.
[0098] The recess 32g or the recess 19g may be a recess formed in the main interior member 32 or the roof liner 19 from the beginning, or may be a recess formed when adding the wiring member 38. In the latter case, it is preferable that a planned break line that is easy to break, such as a thin-walled portion, is formed in the planned formation area of the main interior member 32 or the roof liner 19 where the recess 32g or the recess 19g is to be formed.
[0099] 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 to the interior side can be reduced, and it is less likely to compress the interior space of the vehicle.
[0100] Furthermore, if at least a portion of the first section 42 is along the side edge of the main interior member 32, the portion of the first section 42 will be observed to blend in with the side edge, making the wiring member 38 less noticeable.
[0101] Furthermore, because the second section 46 has the annular slack absorbing portion 43, the second section 46 can be pulled out of the roof liner 19 by extending the slack absorbing portion 43 to eliminate the annular shape. This allows the interior member 30 to move easily. Compared to when slack is set in the entire second section 46, the slack setting point can be set in a fixed position, which stabilizes the pull-out behavior of the second section 46.
[0102] It is not essential that the slack absorbing portion 43 is annular. For example, as shown in Fig. 8, the slack absorbing portion 43B may be a portion where a part of the second section 46 is bent in a wavy shape. In this case, the slack absorbing portion 43B is deformed to approach a straight state, allowing the second section 46 to extend out from the roof liner 19.
[0103] 9, the slack absorbing portion 43C may be a portion where a part of the second section 46 is bent into a spiral shape. In this case, the slack absorbing portion 43C is deformed so as to approach a straight state, allowing the second section 46 to extend out from the roof liner 19. The spiral may be a three-dimensional spiral formed on the circumferential surface of a cylinder, or may be a planar spiral.
[0104] In this embodiment, the additional interior member 40 may be omitted, and the first section 42 may be held by an interior member corresponding to the main interior member 32 .
[0105] In the above embodiment, an example has been described in which the slack absorbing portion 43 is set in the roof liner 19. The slack absorbing portion may be provided in the outer section 44 of the wiring member 38 that extends below the pillar 14. In this case, the slack absorbing portion may be covered by the instrument panel 12.
[0106] In the present embodiment, an example has been described in which the first interior member is an interior member for a pillar and the second interior member is a roof liner. However, the first interior member and the second interior member may be other interior members. For example, the first interior member may be an interior member that covers a passenger airbag in front of the passenger seat, and the second interior member may be an interior member that surrounds the interior member that covers the passenger airbag.
[0107] In the above embodiment, 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.
[0108] Furthermore, 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 to provide the wiring member 38 with the above-mentioned slack absorbing portion.
[0109] The configurations described in the above embodiment and modifications can be combined as appropriate as long as they are not mutually contradictory.
