Abstract
Description
[Technical field]
[0001] The present invention relates to a sun visor for a vehicle. [Background technology]
[0002] An example of a conventional vehicle sun visor is disclosed in Patent Document 1. This vehicle sun visor includes an attachment member, a support shaft, a visor body, a lighting device, a power supply member, a mirror, and a cover.
[0003] The mounting member is attached to the ceiling surface of the vehicle interior. The support shaft is L-shaped with a horizontal shaft portion and a vertical short shaft portion, and the vertical short shaft portion is rotatably held by the mounting member so that the horizontal shaft portion runs along the ceiling surface. When the vertical short shaft portion of the support shaft rotates around its axis, the horizontal shaft portion is displaced between the vicinity of the upper end of the windshield and the vicinity of the upper end of the side window.
[0004] The visor body is supported by the support shaft so as to be rotatable about a horizontally long shaft portion of the support shaft. By rotating about the horizontally long shaft portion, the visor body is displaced between a stored position along the ceiling surface and a usage position along the windshield or side window.
[0005] The lighting device is provided on the visor body. A power supply member for supplying power to the lighting device has a pair of electrodes provided on the support shaft and a connector attached to the mounting member. The connector has a pair of terminals that can come into contact with the contact portions of the pair of electrodes.
[0006] The mirror and the lid are mounted on the visor body. The lid is movable between a closed position that covers the mirror and a fully open position that exposes the mirror.
[0007] In this vehicle sun visor, when the horizontally long shaft portion of the support shaft is near the upper end of the side window, the contact portions of the pair of electrodes and the terminals of the connector are separated and in a non-conductive state. When the horizontally long shaft portion of the support shaft is rotated toward the upper end of the windshield, the contact portions of the pair of electrodes and the terminals of the connector come into contact with each other, and the lighting device is ready to be turned on. In this state, when the cover is moved from the closed position to the fully open position, the switch mechanism is turned on and the lighting device is turned on.
[0008] Another known example of a conventional sun visor for a vehicle is one in which the visor body rotates around the horizontal axis of the support shaft to move from a stored position along the ceiling surface to a usage position along the windshield, thereby switching the power supply member from a non-energized state to a state in which the lighting device is ready to be turned on.
[0009] In this configuration, a pair of first electrodes is provided on the support shaft, and a second electrode is provided on the visor body. When the visor body is in the storage position, the pair of first and second electrodes are separated in the circumferential direction of the horizontally long shaft portion of the support shaft, and are in a non-conductive state. When the visor body is rotated around the horizontally long shaft portion of the support shaft from this storage position to the use position, the pair of first and second electrodes overlap in the circumferential direction and come into contact with each other, and the lighting device is ready to be turned on. [Prior art documents] [Patent documents]
[0010] [Patent Document 1] JP 2019-23015 A Summary of the Invention [Problem to be solved by the invention]
[0011] In the meantime, the above-mentioned another conventional vehicle sun visor may be manufactured in a parts manufacturing factory, and then shipped to a vehicle assembly factory while being packaged with the visor body supported in the usage position relative to the mounting member in order to ensure ease of assembly to the vehicle. In this case, the pair of first and second electrodes are kept in contact with each other during the shipping.
[0012] Here, when the pair of first and second electrodes are made of different metals, particularly when the transportation period is long due to export to an overseas factory, galvanic corrosion may occur at the contact interface between the pair of first and second electrodes during transportation, which may result in poor conductivity.
[0013] The present invention has been made in consideration of the above-mentioned conventional situation, and has an object to provide a sun visor for a vehicle that can prevent galvanic corrosion that occurs between electrodes made of dissimilar metals during transportation from a parts manufacturing plant to a vehicle assembly plant while ensuring ease of assembly to the vehicle when the visor body is in a usage position relative to the mounting member. [Means for solving the problem]
[0014] The vehicle sun visor of the present invention includes: a mounting member that is attached to a ceiling surface of a vehicle compartment; a support shaft that is held by the mounting member and that is disposed along the ceiling surface in a state in which the mounting member is attached to the ceiling surface; a visor body supported by the support shaft so as to be rotatable about the support shaft and displaceable between a stored position along the ceiling surface and a use position rotated from the stored position; A power supply member for supplying power to a lighting device provided on the visor body or the ceiling surface, The power supply member has a pair of first electrodes provided on the support shaft and a second electrode provided on the visor body, which brings the lighting device into a lighting preparation state by contacting the pair of first electrodes, the first electrode and the second electrode are made of different metals, When the visor body is in the stored position with respect to the mounting member, the pair of first electrodes and the pair of second electrodes are separated in the circumferential direction of the support shaft, In a vehicle sun visor configured such that the pair of first electrodes and the pair of second electrodes overlap in the circumferential direction when the visor body is in the use position relative to the mounting member, In a state before the vehicle sun visor is attached to the ceiling surface, the second electrode and the pair of first electrodes are interposed between the second electrode and the pair of first electrodes provided on the visor body in the use position relative to the attachment member to prevent contact between the pair of first electrodes and the second electrodes, and The vehicle sun visor is characterized by having an insulating contact-preventing member that is removed from between the second electrode and the pair of first electrodes after the vehicle sun visor is attached to the ceiling surface, thereby enabling contact between the pair of first electrodes and the second electrode.
[0015] The vehicle sun visor of the present invention is configured such that a pair of first and second electrodes overlap in the circumferential direction when the visor body is in a usage position relative to the mounting member. Therefore, if no intermediate object is interposed between the pair of first and second electrodes, and the vehicle sun visor is transported from a parts manufacturing plant to a vehicle assembly plant with the visor body maintained in a usage position relative to the mounting member, there is a risk of galvanic corrosion occurring due to contact between the pair of first and second electrodes made of dissimilar metals.
[0016] In this regard, in the vehicle sun visor of the present invention, an insulating contact prevention member is interposed between the second electrode provided on the visor body in the use position relative to the mounting member and the pair of first electrodes. Therefore, even if the vehicle sun visor of the present invention is transported from a parts manufacturing factory to a vehicle assembly factory with the visor body maintained in the use position relative to the mounting member, contact between the pair of first and second electrodes is prevented by the contact prevention member during transportation, so there is no risk of galvanic corrosion occurring. As a result, even if the vehicle sun visor of the present invention is transported from a parts manufacturing factory to a vehicle assembly factory with the visor body maintained in the use position relative to the mounting member, galvanic corrosion can be prevented during transportation.
[0017] Therefore, according to the vehicle sun visor of the present invention, when the ease of assembly to the vehicle can be ensured when the visor body is in the usage position relative to the mounting member, it is possible to prevent galvanic corrosion that occurs between electrodes made of dissimilar metals during transportation from the parts manufacturing plant to the vehicle assembly plant while ensuring the ease of assembly to the vehicle.
[0018] After the vehicle sun visor is attached to the ceiling surface of the vehicle compartment, the contact prevention member is removed from between the second electrode and the pair of first electrodes, allowing the pair of first electrodes to come into contact with the pair of second electrodes. Therefore, when the visor body is in a use position relative to the attachment member after the contact prevention member is removed from between the first electrode and the second electrode, the pair of first electrodes and the second electrodes overlap in the circumferential direction and come into contact with each other. This puts the lighting device into a lighting preparation state.
[0019] The contact prevention member is preferably a resin film interposed between the second electrode and the pair of first electrodes before the vehicle sun visor is attached to the ceiling surface. The vehicle sun visor of the present invention preferably further includes a mirror provided on the visor body, a lid provided on the visor body and displaceable between a closed position that covers the mirror and a fully open position that exposes the mirror, and a connecting member having one end connected to the resin film and the other end connected to the lid. The connecting member is preferably configured to be interlocked with the movement of the lid from the closed position toward the fully open position, so that the resin film is removed from between the second electrode and the pair of first electrodes.
[0020] In this case, before the vehicle sun visor is attached to the ceiling surface, the resin film interposed between the second electrode and the pair of first electrodes prevents contact between the pair of first electrodes and the pair of second electrodes. This makes it possible to prevent galvanic corrosion occurring between the pair of first electrodes and the pair of second electrodes. In addition, the connecting member is linked to the movement of the cover from the closed position toward the fully open position, which removes the resin film from between the second electrode and the pair of first electrodes. Therefore, after the vehicle sun visor is assembled to the vehicle, for example, when the user opens the cover for the first time, the resin film can be removed from between the second electrode and the pair of first electrodes.
[0021] The connecting member is preferably a string-like body, and the visor body preferably has a guide portion that guides the pulling direction of the string-like body in a direction to prevent the resin film removed from between the second electrode and the pair of first electrodes by the string-like body from interfering with the second electrode.
[0022] In this case, the string-like body is pulled by the lid moving from the closed position to the fully open position, and the resin film is removed from between the second electrode and the pair of first electrodes. At this time, the pulling direction of the string-like body is guided by the guide portion in a direction that prevents the resin film removed from between the second electrode and the pair of first electrodes from interfering with the second electrode. Therefore, the resin film can be smoothly removed from between the second electrode and the pair of first electrodes while avoiding interference between the resin film and the second electrode.
[0023] The visor body preferably has a holding portion that holds the resin film removed from between the second electrode and the pair of first electrodes.
[0024] In this case, the resin film removed from between the second electrode and the pair of first electrodes is held by the holding portion, and therefore, for example, it is possible to prevent the resin film from interfering with opening and closing of the lid.
[0025] The length of the string is preferably set so that the resin film is held by the holding portion when the lid is in the fully open position.
[0026] In this case, after the vehicle sun visor is assembled to the vehicle, for example, when the user fully opens the cover for the first time, the resin film removed from between the second electrode and the pair of first electrodes can be held in the holding portion, thereby preventing the resin film from interfering with the opening and closing of the cover thereafter.
[0027] The contact prevention member is preferably a coating film formed on a contact interface between the pair of first and second electrodes, and the coating film is preferably configured to be removed by friction between the pair of first and second electrodes when the visor body moves between the use position and the retracted position.
[0028] In this case, after the vehicle sun visor is assembled to the vehicle, for example, when an assembly worker rotates the visor body from the use position to the storage position relative to the mounting member, the coating film is removed from the contact interface between the pair of first electrodes and second electrodes due to friction between the coating film and the pair of first electrodes and second electrodes. Effect of the Invention
[0029] According to the vehicle sun visor of the present invention, when the ease of assembly to the vehicle can be ensured when the visor body is in the usage position relative to the mounting member, galvanic corrosion that occurs between electrodes made of dissimilar metals during transportation from the parts manufacturing plant to the vehicle assembly plant can be prevented while ensuring the ease of assembly to the vehicle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0031] Hereinafter, first and second embodiments of the present invention will be described with reference to the drawings.
[0032] Example 1 As shown in FIG. 1, a vehicle sun visor (hereinafter, referred to as "sun visor" as appropriate) 10 of the first embodiment is an example of a vehicle sun visor of the present invention, and is mounted on a vehicle. Specifically, the vehicle is a passenger car. The sun visor 10 is attached to a ceiling surface 2 of the passenger compartment near a windshield 1. In this embodiment, the sun visor 10 is attached behind the windshield 1 and in front of the driver's seat. The sun visor 10 may also be attached on the passenger seat side.
[0033] In the following description, the up-down direction and the left-right direction of the vehicle are defined by the arrows shown in Fig. 1. The left-right arrows shown in Fig. 1 define the left-right direction when looking at the front of the vehicle from inside the vehicle cabin. Also, in Fig. 2 and subsequent figures, the up-down direction, the left-right direction, and the front-rear direction of the vehicle are defined in accordance with Fig. 1. Since the sun visor 10 is attached to the vehicle, the left-right direction, etc. of the sun visor 10 coincide with the left-right direction, etc. of the vehicle, but in the sun visor 10 shown in Fig. 2 and subsequent figures, the up-down direction, the left-right direction, and the front-rear direction of the sun visor 10 are shown in a state in which the visor body 40 is maintained in a use position relative to the mounting member 20 described later.
[0034] The sun visor 10 includes a mounting member 20, a support shaft 30, and a visor body 40.
[0035] 5, the mounting member 20 is fixed to a ceiling surface 2 of the vehicle interior with screws 3. The mounting member 20 is mounted to the ceiling surface 2 in a vehicle assembly plant while the visor body 40 is maintained in a usage position relative to the mounting member 20, which will be described later, in order to ensure ease of assembly to the vehicle.
[0036] As shown in FIGS. 8 and 9, a connector 21 that is electrically connected to a vehicle battery (not shown) is detachably attached to the mounting member 20.
[0037] As shown in Fig. 2, the support shaft 30 is L-shaped and has a horizontally long shaft portion 31 and a vertically short shaft portion 32. The support shaft 30 is made of a resin injection molding. As shown in Figs. 6 and 7, the end of the horizontally long shaft portion 31 opposite the vertically short shaft portion 32 is a thin shaft portion 33 that is thinner than other portions.
[0038] The support shaft 30 is held by the mounting member 20. With the support shaft 30 held by the mounting member 20 attached to the ceiling surface 2, the horizontally long shaft portion 31 is disposed substantially parallel to the ceiling surface 2, and the vertically short shaft portion 32 hangs down from the ceiling surface 2. The vertically short shaft portion 32 of the support shaft 30 is rotatably held by the mounting member 20. As the vertically short shaft portion 32 of the support shaft 30 rotates about its axis, the horizontally long shaft portion 31 is displaced between the vicinity of the upper end of the windshield 1 and the vicinity of the upper end of the side window 4.
[0039] The visor body 40 is a thick, hollow, plate-like member having a substantially rectangular outer shape, and is formed by stacking two resin plates in the thickness direction. The horizontally long shaft portion 31 of the support shaft 30 is rotatably inserted from the right end into the long side portion on one end of the visor body 40. An auxiliary shaft portion 41 is provided on the left end side of the long side portion on one end of the visor body 40. The horizontally long shaft portion 31 and the auxiliary shaft portion 41 are concentrically arranged.
[0040] As shown in FIG. 1, the auxiliary shaft portion 41 is removably held by a substantially U-shaped hook portion 5 provided on the ceiling surface 2. With the auxiliary shaft portion 41 held by the hook portion 5, the visor body 40 rotates around the horizontally long shaft portion 31 of the support shaft 30 and the auxiliary shaft portion 41 as the rotation axis center, so that the visor body 40 changes between a stored posture along the ceiling surface 2 and a use posture along the windshield 1 by rotating about 90 degrees from the stored posture. The ceiling surface 2 is provided with a recess 6 for storing the visor body 40 in the stored posture state. The visor body 40 is disposed substantially parallel to the windshield 1 by rotating about 90 degrees from the stored posture. The visor body 40 is capable of adjusting the opening degree at any angle between the stored posture and the use posture when rotated to be along the windshield 1. By removing the auxiliary shaft portion 41 from the hook portion 5, the visor body 40 becomes rotatable around the vertical short shaft portion 32.
[0041] A lighting device 7 for illuminating the driver's seat and its surroundings is provided in the recess 6 of the ceiling surface 2. As shown in Figures 8 and 9, one end of a pair of lead wires 8 is connected to the lighting device 7. The other end of the pair of lead wires 8 is connected to a connector 21 attached to a mounting member 20, and the lighting device 7 is turned on by receiving power from an on-board battery (not shown) of the vehicle.
[0042] The sun visor 10 includes a power supply member 50, a mirror 60, and a cover 70.
[0043] The mirror 60 is provided on a surface of the visor body 40 facing the driver's seat (rear of the vehicle) when the visor body 40 is in a use position along the windshield 1. The mirror 60 is disposed on one side (right side) of the center of the visor body 40 in the longitudinal direction (left-right direction).
[0044] The lid 70 is provided on the surface of the visor body 40 on which the mirror 60 is provided, so as to be slidable in the longitudinal direction of the visor body 40. The lid 70 is displaced between a closed position that covers the mirror 60 and a fully open position that exposes the entire mirror 60, by sliding in the longitudinal direction of the visor body 40. The lid 70 is displaced from the closed position to the fully open position by sliding leftward, and is displaced from the fully open position to the closed position by sliding rightward. Most of the lid 70 in the fully open position is accommodated inside the visor body 40.
[0045] The power supply member 50 supplies power to the lighting fixture 7 provided on the ceiling surface 2. The power supply member 50 has a pair of first electrodes 51 and a pair of second electrodes 52. The first electrodes 51 and the second electrodes 52 are made of different metals. In this embodiment, the first electrodes 51 are made of stainless steel suitable for insert molding, and the second electrodes 52 are made of copper having an elastic restoring force.
[0046] The pair of first electrodes 51 are provided on the support shaft 30. The pair of first electrodes 51 are built into the support shaft 30 by insert molding. One end of the pair of first electrodes 51 protrudes from the end of the vertical short shaft portion 32 of the support shaft 30 and is connected to the connector 21 attached to the mounting member 20. The other end of the pair of first electrodes 51 is exposed at the end of the horizontally long shaft portion 31 of the support shaft 30 opposite to the vertical short shaft portion 32 at the thin shaft portion 33 and protrudes leftward from the thin shaft portion 33, as shown in Figs. 6 and 7. The protruding tip of the pair of first electrodes 51 protruding from the thin shaft portion 33 of the horizontally long shaft portion 31 is covered with a cap 34. That is, the pair of first electrodes 51 has an exposed portion 51a exposed at the thin shaft portion 33 of the horizontally long shaft portion 31.
[0047] The pair of second electrodes 52 are built into the visor body 40. As shown in Fig. 6 and Fig. 7, the pair of second electrodes 52 have a bent abutment portion 52a at one end. The ends of the pair of second electrodes 52 that are further toward the tip side than the bent abutment portion 52a extend in directions away from each other. The pair of second electrodes 52 are set in the horizontally elongated shaft portion 31 such that the bent abutment portion 52a is located within the range of the thin shaft portion 33.
[0048] When the visor body 40 is in the use position relative to the mounting member 20, as shown in Fig. 6, the exposed portions 51a of the pair of first electrodes 51 and the bent abutting portions 52a of the pair of second electrodes 52 overlap in the circumferential direction of the horizontal shaft portion 31, and each exposed portion 51a and each bent abutting portion 52a come into contact with each other. This puts the pair of first electrodes 51 and the pair of second electrodes 52 in a conductive state, and the lighting device 7 is in a lighting preparation state. In addition, in this sun visor 10, when the visor body 40 in the storage position rotates around the horizontal shaft portion 31 by a predetermined angle or more, the exposed portions 51a of the pair of first electrodes 51 and the bent abutting portions 52a of the pair of second electrodes 52 overlap in the circumferential direction of the horizontal shaft portion 31, and the pair of first electrodes 51 and the pair of second electrodes 52 are set in a conductive state.
[0049] On the other hand, when the visor body 40 is in a stored position relative to the mounting member 20, as shown in Figure 7, the exposed portions 51a of the pair of first electrodes 51 and the bent abutment portions 52a of the pair of second electrodes 52 are separated in the circumferential direction of the horizontal shaft portion 31, and the pair of first electrodes 51 and the pair of second electrodes 52 are in an inconvenient state.
[0050] As shown in FIG. 8, when the cover 70 is in a closed position covering the mirror 60, the ends 52b on the other end side of the pair of second electrodes 52 are separated from each other. Also, as shown in FIG. 9, when the cover 70 is in a fully open position exposing the entire mirror 60, the ends 52b on the other end side of the pair of second electrodes 52 are pressed by one end surface 70a of the cover 70, and the ends 52b are in contact with each other. When the cover 70 returns from the fully open position to the closed position, the pair of second electrodes 52 elastically restores its original shape, and the ends 52b are separated from each other. In this sun visor 10, when the cover 70 is opened to a half-open position exposing about half of the mirror 60, the ends 52b of the pair of second electrodes 52 are pressed by the cover 70, and the ends 52b are in contact with each other.
[0051] In this sun visor 10, the pair of second electrodes 52 and the lid 70 constitute a switch mechanism for controlling the lighting of the lighting device 7. That is, when the visor body 40 is in the use position and the exposed parts 51a of the pair of first electrodes 51 and the bent abutting parts 52a of the pair of second electrodes are in contact with each other and are in a state in which electricity can be passed, if the lid 70 is opened from the closed position to the half-open position or more, the ends 52b of the pair of second electrodes 52 come into contact with each other, the switch mechanism is turned on, and the lighting device 7 is turned on. On the other hand, even when the visor body 40 is in the use position and the exposed parts 51a of the pair of first electrodes 51 and the bent abutting parts 52a of the pair of second electrodes are in contact with each other and are in a state in which electricity can be passed, if the lid 70 is in the closed position less than the half-open position, the ends 52b of the pair of second electrodes 52 separate from each other, the switch mechanism is turned off, and the lighting device 7 is turned off. Furthermore, even if the lid 70 is opened to the half-open position or further, when the visor body 40 is in the stored position, the exposed portions 51a of the pair of first electrodes 51 and the bent abutment portions 52a of the pair of second electrodes are out of contact with each other and no electricity can flow between them, so that the lighting device 7 does not light up.
[0052] Here, the sun visor 10 includes a resin film 80 and a string 90. The resin film 80 is an example of a "contact prevention member" in the present invention. The string 90 is an example of a "string-like body" serving as a "connecting member" in the present invention.
[0053] The resin film 80 is made of polyvinyl chloride, and is soft and insulating. The resin of the resin film 80 may be other resins as long as they are soft and insulating. As shown in Fig. 3, the resin film 80 has a cylindrical shape. The resin film 80 has slits (perforations) 80a as weak parts extending entirely in the axial direction.
[0054] As shown in Figs. 2 and 4, the resin film 80 covers the exposed portions 51a of the pair of first electrodes 51 and is disposed between the pair of first electrodes 51 and the pair of second electrodes 52. That is, when the sun visor 10 is manufactured in a parts manufacturing factory, the pair of first electrodes 51 are integrally provided on the support shaft 30 by insert molding, and before the cap 34 is placed on the protruding tip of the other end side of the first electrodes 51, the resin film 80 is placed on the protruding tip side, so that the exposed portions 51a of the first electrodes 51 are covered with the resin film 80. At this time, it is preferable to position the slit 80a at a portion or in the vicinity of the portion in the opposite direction to the pulling direction in which the resin film 80 is pulled by the string 90 from between the first electrode 51 and the second electrode 52. This makes it easier for the resin film 80 broken from the slit 80a to be removed from between the first electrode 51 and the second electrode 52.
[0055] The string 90 is disposed within the visor body 40. The material of the string 90 is not particularly limited, but may be a resin such as polypropylene or nylon, or a cloth. One end of the string 90 is fixed to a right end of the resin film 80 that covers the exposed portions 51a of the pair of first electrodes 51. The other end of the string 90 is fixed to a fixing portion 70b that protrudes from a left end of one end surface 70a of the lid 70. The fixing portion 70b is also disposed within the visor body 40.
[0056] The visor body 40 has a pulley 42 and a cylindrical body 43. The pulley 42 is an example of the "guide portion" in the present invention. The cylindrical body 43 is an example of the "holding portion" in the present invention.
[0057] The pulley 42 and the cylinder 43 are provided inside the visor body 40. The pulley 42 reverses the pulling direction of the hung string 90. The pulley 42 is disposed on one side (right side) of the visor body 40 in the longitudinal direction of the visor body 40 from the thin shaft portion 33 of the horizontally long shaft portion 31 of the support shaft 30. The cylinder 43 is disposed on the other side (left side) of the visor body 40 in the longitudinal direction from the thin shaft portion 33 of the horizontally long shaft portion 31 of the support shaft 30, and in the vicinity of the fixed portion 70b of the lid 70 in the closed position. The string 90, one end of which is fixed to the resin film 80 between the pair of first electrodes 51 and the pair of second electrodes 52, extends obliquely downward to the right, reaches the pulley 42, and is reversed by the pulley 42. The other end of the string 90 that is reversed at the pulley 42 extends leftward and passes through the inside of the cylindrical body 43, and the other end of the string 90 is fixed to the fixed part 70b.
[0058] The cylinder 43 has a through hole and is capable of holding the resin film 80 that reaches the through hole.
[0059] 9, the string 90 is set to a length equal to the distance between the fixing portion 70b of the lid 70 in the fully open position and the cylindrical body 43. In other words, the length of the string 90 is set so that when the lid 70 moves from the closed position to the fully open position, the resin film 80 that is pulled by the string 90 and removed from between the pair of first electrodes 51 and the pair of second electrodes 52 just reaches the cylindrical body 43.
[0060] When the sun visor 10 is manufactured in a parts manufacturing factory and then transported to a vehicle assembly factory, the visor body 40 is packaged in a state where it is maintained in a usage position relative to the mounting member 20 in order to ensure the assembly work to the vehicle at the vehicle assembly factory. That is, during transportation from the parts manufacturing factory to the vehicle assembly factory, the exposed portions 51a of the pair of first electrodes 51 and the bent abutting portions 52a of the pair of second electrodes 52 overlap in the circumferential direction of the horizontally long shaft portion 31. For this reason, if there is no intervening object between the first electrode 51 and the second electrode 52, there is a risk of galvanic corrosion occurring during transportation due to contact between the first electrode 51 and the second electrode 52 made of different metals.
[0061] In this regard, in the sun visor 10, the resin film 80 covers the exposed portions 51a of the pair of first electrodes 51 and is disposed between the pair of first electrodes 51 and the pair of second electrodes 52. Therefore, the resin film 80 prevents contact between the first electrodes 51 and the second electrodes 52. As a result, it is possible to prevent galvanic corrosion from occurring between the first electrodes 51 and the second electrodes 52 during transportation of the sun visor 10 from a parts manufacturing plant to a vehicle assembly plant.
[0062] Therefore, according to this sun visor 10, when the ease of assembly to the vehicle can be ensured when the visor body 40 is in the usage position relative to the mounting member 20, it is possible to prevent galvanic corrosion occurring between electrodes made of dissimilar metals during transportation from a parts manufacturing plant to a vehicle assembly plant while ensuring the ease of assembly to the vehicle.
[0063] Furthermore, after the sun visor 10 is attached to the ceiling surface 2 at a vehicle assembly plant, when, for example, a user who has purchased a new car opens the lid 70 for the first time from the closed position toward the fully open position to the half-open position or higher, the resin film 80 is removed from between the first electrode 51 and the second electrode 52 in conjunction with the movement of the lid 70. As a result, the pair of first electrodes 51 and the pair of second electrodes 52 can come into contact with each other.
[0064] That is, when the lid 70 in the closed position is opened toward the fully open position, the string 90 pulls the resin film 80 in conjunction with the movement of the lid 70, and removes it from between the first electrode 51 and the second electrode 52. In detail, when the lid 70 moves from the closed position toward the fully open position, one end of the string 90 fixed to the fixing portion 70b of the lid 70 is pulled to the left. Since the pulling direction of the string 90 is reversed by the pulley 42, the resin film 80 fixed to the other end side of the string 90 is pulled diagonally downward toward the right. As a result, the resin film 80 is torn starting from the slit 80a, and the resin film 80 is pulled diagonally downward to the right to avoid interference with the pair of second electrodes 52, and is removed from between the first electrode 51 and the second electrode 52.
[0065] In particular, in this sun visor 10, for example, when a user opens the lid 70 from the closed position to the fully open position, when the lid 70 reaches the fully open position, the resin film 80, which has been pulled by the string 90 and removed from between the first electrode 51 and the second electrode 52, is held by the cylindrical body 43. This makes it possible to prevent the resin film 80 from interfering with the subsequent opening and closing movement of the lid 70.
[0066] Example 2 As shown in FIG. 10, in the sun visor of the second embodiment, a coating film 100 is used as a contact prevention member in the present invention, instead of the resin film 80 in the sun visor 10 of the first embodiment.
[0067] That is, in the sun visor of Example 2, the resin film 80, the string 90, the pulley 42, the cylinder 43, and the fixing portion 70b of the lid 70 in the sun visor 10 of Example 1 are omitted. In the sun visor of Example 2, a coating film 100 is formed on the contact interface between the exposed portions 51a of the pair of first electrodes 51 and the bent abutment portions 52a of the pair of second electrodes 52. In this sun visor, the coating film 100 is formed on the surface of the second electrode 52 facing the exposed portions 51a of the first electrodes 51, in a range including and near the bent abutment portions 52a.
[0068] The coating film 100 is made of polyvinyl chloride. The material of the coating film 100 may be any material having insulating properties, and may be resin other than polyvinyl chloride or ceramic.
[0069] The coating film 100 can be formed in advance on a predetermined portion of the second electrode 52 before the second electrode 52 is set on the horizontally elongated shaft portion 31 of the support shaft 30.
[0070] The thickness of the coating film 100 can be set to such that, by interposing the coating film 100 between the first electrode 51 and the second electrode 52, galvanic corrosion occurring between the two electrodes can be effectively prevented when the sun visor is transported from a parts manufacturing plant to a vehicle assembly plant, and that, after the sun visor is assembled to a vehicle, when, for example, an assembly worker rotates the visor body 40, which is in a usage position relative to the mounting member 20, from the usage position to the storage position for the first time, the coating film 100 is removed by friction between the coating film 100 and the pair of first electrodes 51 and the pair of second electrodes 52.
[0071] The thickness of the coating film 100 may be such that, after the sun visor is assembled to the vehicle, the coating film 100 is removed by friction between the pair of first electrodes 51 and the pair of second electrodes 52 when, for example, an assembly worker repeatedly rotates the visor body 40 relative to the mounting member 20 between the use position and the storage position several times.
[0072] In the sun visor of Example 2, when the sun visor is transported from a parts manufacturing factory to a vehicle assembly factory, contact between the exposed portions 51a of the pair of first electrodes 51 and the bent abutment portions 52a of the pair of second electrodes 52 is prevented by the coating film 100, thereby preventing galvanic corrosion from occurring between the first electrodes 51 and the second electrodes 52 during transportation.
[0073] In addition, after this sun visor is attached to the ceiling surface 2 at a vehicle assembly plant, for example, an assembly worker can rotate the visor body 40, which is in a usage position relative to the mounting member 20, from the usage position to a storage position, whereby the coating film 100 can be removed from between the first electrodes 51 and the second electrodes 52 due to friction between the coating film 100 and the pair of first electrodes 51 and the pair of second electrodes 52.
[0074] The other configurations and effects are the same as those of the first embodiment.
[0075] In the above, the present invention has been described based on Examples 1 and 2. However, the present invention is not limited to the above Examples 1 and 2, and it goes without saying that the present invention can be modified as appropriate without departing from the spirit of the present invention.
[0076] In the first and second embodiments, the lighting device 7 is provided on the ceiling surface 2, but the present invention is not limited to this configuration, and the lighting device 7 may be provided on the visor body 40.
[0077] In the first and second embodiments, a switch mechanism is used to turn on the lighting device 7 in conjunction with the movement of the lid 70, which is in the closed position, to be opened; however, the present invention is not limited to this configuration, and the lighting device 7 may be turned on by another switch mechanism that operates independently of the movement of the lid 70.
[0078] In the first embodiment, a string-like body is used as the connecting member that connects the resin film 80 and the lid 70, but the present invention is not limited to this, and a link mechanism or the like may be used as the connecting member. Moreover, instead of the string 90, a flexible wire or the like may be used as the string-like body.
[0079] In the sun visor of Example 2, the lid 70 for the mirror 60 is not required to remove the coating film 100 from between the first electrode 51 and the second electrode 52, so the mirror 60 and the lid 70 may be omitted in the sun visor of Example 2. [Industrial Applicability]
