Description

[Technical Field]

[0001] The present invention relates to a structure of a vehicle static eliminator and a structure of a vehicle to which the vehicle static eliminator is attached. [Background technology]

[0002] It has been known that positive static electricity can build up on the body of a vehicle due to external factors, including the vehicle being insulated from the road surface as it travels on the road, and that this positive static electricity can have some effect on the operation of the vehicle. As a countermeasure against this positive static electricity building up on the body, a structure has been proposed in which a positively charged member and a negatively charged member are arranged on the seat so that they rub against each other in accordance with the passenger's movements, and the negatively charged member and the body are connected by a ground wire (see, for example, Patent Document 1). With this structure, negative static electricity generated on the negatively charged member by the rubbing is passed through the ground wire to the body, neutralizing and eliminating the positive charge on the body. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2019-117709 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the static eliminator described in Patent Document 1 requires an earth wire to connect the negatively charged member to the body, and the seat cover needs to be made of negatively charged members or positively charged members that are different from normal cover materials, which makes it difficult to install in a user's vehicle after the sale.

[0005] SUMMARY OF THE INVENTION Therefore, an object of the present invention is to neutralize static electricity from a user-owned vehicle using a simple configuration. [Means for solving the problem]

[0006] The vehicle static eliminator of the present invention is characterized by comprising a first zero potential member that is in direct or indirect contact with a metal interior member attached to the vehicle body and has a frictional electrification potential of zero, and a negatively charged member that is stacked so as to frictionally slide against the first zero potential member and is charged with negative static electricity due to sliding friction with the first zero potential member, and neutralizes and eliminates static electricity from the body that is charged with positive static electricity.

[0007] This configuration generates induced polarization in the first zero potential member, and the negatively charged member neutralizes the negatively charged static electricity with the positively charged metal interior component, thereby neutralizing static electricity from the vehicle body equipped with the metal interior component.

[0008] In the vehicle static eliminator of the present invention, the first zero potential member may be made of natural fiber having a zero potential in the triboelectric column, and the negatively charged member may be made of a resin material.

[0009] This allows the vehicle static eliminator to be constructed using common materials, resulting in a simple construction.

[0010] The vehicle static eliminator of the present invention may further comprise a second zero potential member laminated on the surface of the negatively charged member opposite to the first zero potential member, and the second zero potential member may be a natural fiber having a zero potential in a triboelectric series table.

[0011] This configuration prevents negative static electricity generated in the negatively charged member from being discharged to the outside from the side opposite the metal interior member. Therefore, the vehicle static eliminator can efficiently neutralize the negative static electricity generated in the negatively charged member by neutralizing it with the positive static electricity that is charged to the metal interior member.

[0012] The vehicle static eliminator of the present invention may further include an antistatic resin member laminated on the surface of the negatively charged member opposite the first zero potential member, and the antistatic resin member may be attached to the negatively charged member with an adhesive.

[0013] This prevents negatively charged static electricity generated in the negatively charged member from being discharged to the outside from the opposite side of the metal interior member, and therefore the vehicle static eliminator can efficiently neutralize the negatively charged static electricity generated in the negatively charged member by neutralizing it with the positively charged static electricity that is charged to the metal interior member.

[0014] The vehicle of the present invention is a vehicle equipped with a vehicle static eliminator, and is equipped with a seat including a seat frame which is an interior member, a first seat cover which covers the outside of the seat frame, and a second seat cover which covers the outside of the first seat cover, wherein the vehicle static eliminator is sandwiched between the first seat cover and the second seat cover, the first zero potential member is arranged so as to indirectly contact the seat frame via the first seat cover, and the negatively charged member is sandwiched between the first zero potential member and the second seat cover and is pressed against the first zero potential member so as to be able to frictionally slide against it.

[0015] In this way, disposing the vehicle static eliminator between the first seat cover and the second seat cover of the seat makes it possible to neutralize the body, thereby enabling a user's vehicle to be neutralized with a simple configuration. Also, the negatively charged member is charged with negative static electricity through sliding friction with the first zero potential member due to the start of the vehicle, vibrations while driving, etc., so that the body can be neutralized simply by disposing the vehicle static eliminator.

[0016] The vehicle of the present invention is a vehicle equipped with a vehicle static eliminator, and comprises a seat including a seat frame as an interior member, a first seat cover covering the outside of the seat frame, and a second seat cover covering the outside of the first seat cover, wherein the vehicle static eliminator is sandwiched between the first seat cover and the second seat cover, the first zero potential member is arranged so as to indirectly contact the seat frame via the first seat cover, the second zero potential member has one surface laminated on the surface of the negatively charged member opposite the seat frame and the other surface arranged so as to contact the second seat cover, and the negatively charged member is sandwiched between the first zero potential member and the second zero potential member and is pressed against the first zero potential member so as to be able to frictionally slide.

[0017] In this way, disposing the vehicle static eliminator between the first and second seat covers of the seat enables static elimination of the body, thereby enabling static elimination of a user's vehicle with a simple configuration. Furthermore, because the second zero potential member is laminated on the surface of the negatively charged member opposite the seat frame, negative static electricity generated in the negatively charged member can be prevented from discharging to the outside from the side opposite the seat frame. Therefore, the vehicle static eliminator can efficiently neutralize negative static electricity generated in the negatively charged member by neutralizing it with positive static electricity that charges the seat frame. Furthermore, the negatively charged member is charged with negative static electricity through sliding friction caused by vehicle startup, running vibrations, and the like, so static elimination of the body can be achieved simply by disposing the vehicle static eliminator.

[0018] The vehicle of the present invention is a vehicle equipped with a vehicle static eliminator, and is equipped with a seat including a seat frame as an interior member, a first seat cover covering the outside of the seat frame, and a second seat cover covering the outside of the first seat cover, wherein the vehicle static eliminator is sandwiched between the first seat cover and the second seat cover, the first zero potential member is arranged so as to indirectly contact the seat frame via the first seat cover, the antistatic resin member has one surface laminated on the surface of the negatively charged member opposite the seat frame and the other surface arranged so as to contact the second seat cover, and the negatively charged member is pressed against the first zero potential member so as to be able to frictionally slide.

[0019] In this way, because the antistatic resin member is laminated on the surface of the negatively charged member opposite the seat frame, negative static electricity generated in the negatively charged member can be prevented from discharging to the outside from the side opposite the seat frame. Therefore, the vehicle static eliminator can efficiently neutralize negative static electricity generated in the negatively charged member by neutralizing it with positive static electricity that is charging the seat frame. Furthermore, because the negatively charged member is charged with negative static electricity through sliding friction caused by starting the vehicle, running vibrations, etc., simply by installing the vehicle static eliminator, static electricity can be eliminated from the body.

[0020] The vehicle of the present invention is a vehicle equipped with a vehicle static eliminator, and includes a seat having a seat frame which is an interior member, wherein the vehicle static eliminator is attached so that the first zero potential member is in direct contact with the seat frame, the second zero potential member is laminated on the surface of the negatively charged member opposite the seat frame and is pressed against the seat frame with an outer cover which covers the outer surface of the second zero potential member, and the negatively charged member is sandwiched between the first zero potential member and the second zero potential member and is pressed against the first zero potential member so as to be able to frictionally slide. Characterized by

[0021] This makes it possible to neutralize the body with a simple configuration.

[0022] In the vehicle of the present invention, the seat may include a back frame that supports the back of the occupant, the first seat cover covering the rear surface of the back frame, and the second seat cover overlapping the rear surface of the first seat cover to form a seat pocket on the rear surface of the seat.

[0023] In this way, static electricity can be easily removed from the body of the vehicle by simply inserting the vehicle static eliminator into the seat pocket.

[0024] In the vehicle of the present invention, the seat may include a back frame that supports the back of the occupant, the first seat cover may cover the rear surface of the back frame, and the second seat cover may be a rear cover whose peripheral portion is fixed to the surface of the first seat cover and which presses the negatively charged member and the first zero potential member together so that they can slide and frictionally contact each other.

[0025] This makes it possible to neutralize the body with a simple configuration.

[0026] In the vehicle of the present invention, the seat may include a recess for accommodating a retractable armrest and a back frame for supporting the occupant's back, the first seat cover may be a bottom cover that covers the front surface of the back frame with the bottom surface of the recess, and the second seat cover may be a front cover whose peripheral portion is fixed to the surface of the bottom cover and that presses the negatively charged member and the first zero potential member together so that they can slide frictionally.

[0027] This makes it possible to neutralize the body with a simple configuration.

[0028] The vehicle of the present invention may include a box provided adjacent to the seat, the seat having a back frame that supports the back of an occupant, the first seat cover being a first side cover that covers the side of the back frame with the side of the interior of the box, and the second seat cover being a second side cover whose peripheral portion is fixed to the surface of the first side cover and that frictionally and slidably presses the negatively charged member and the first zero potential member together.

[0029] This makes it possible to neutralize the body with a simple configuration.

[0030] In the vehicle of the present invention, the first zero potential member may be disposed so that an entire surface of the first zero potential member is in direct or indirect contact with the seat frame.

[0031] This allows the body to be effectively neutralized.

[0032] In the vehicle of the present invention, the seat frame may include a main frame that supports the buttocks of an occupant and a back frame that supports the back of the occupant, the seat may include a cushion attached to the main frame and a backrest attached to the back frame, and an antistatic agent may be applied to the seating surface of the cushion and the backrest surface of the backrest. The cushion and the backrest may have surfaces made of synthetic resin material, and the antistatic agent may contain a cationic surfactant, or the cushion and the backrest may have surfaces made of leather material, and the antistatic agent may contain a fluororesin agent.

[0033] This allows the body to be neutralized more effectively. [Effects of the Invention]

DETAILED DESCRIPTION OF THE INVENTION

[0036] Hereinafter, vehicles 100, 110, 120, 130, 140, 150, and 160 and vehicle static eliminators 30, 35, 38, and 39 according to embodiments will be described with reference to the drawings. The vehicles 100, 110, 120, 130, 140, 150, and 160 are user-owned vehicles that are owned by users after sale. First, the vehicle static eliminator 30 according to the first embodiment and the vehicle 100 to which the vehicle static eliminator 30 is attached will be described with reference to FIGS. 1 to 3. Note that the arrows FR, UP, and RH shown in each drawing indicate the front, upper, and right sides of the vehicles 100, 110, 120, 130, 140, 150, and 160, respectively. The opposite directions of the arrows FR, UP, and RH indicate the rear, lower, and left sides. In the following description, when simply using the terms front-rear, left-right, and up-down, unless otherwise specified, this refers to the front-rear direction of each vehicle 100, 110, 120, 130, 140, 150, and 160, the left-right direction of each vehicle, and the up-down direction of each vehicle.

[0037] As shown in FIG. 1, a vehicle 100 includes a body 10, a seat 20, and a vehicle static eliminator 30. The body 10 includes a floor cloth 12 and a floor panel 11. The floor cloth 12 is a structural member that constitutes the body 10 and is a channel-shaped member that extends in the vehicle width direction. The floor panel 11 is attached on top of the floor cloth 12 to constitute the floor of the passenger compartment. The floor cloth 12 and the floor panel 11 are made of metal.

[0038] The seat 20 includes a seat frame 21, a cushion 26, and a backrest 27. The seat frame 21 is a strength member that supports the occupant and constitutes a metal interior member. The seat frame 21 is composed of a main frame 21A that supports the occupant's buttocks, a back frame 21B that supports the occupant's back, and a hinge 23. The main frame 21A, the back frame 21B, and the hinge 23 are all made of metal. The main frame 21A is attached to the floor panel 11 by a metal front bracket 24F and a metal rear bracket 24R, and supports the weight of the occupant. The hinge 23 is provided at the rear end of the main frame 21A. The back frame 21B is attached by the hinge 23 so as to be rotatable relative to the main frame 21A. Therefore, the main frame 21A, the hinge 23, and the back frame 21B are electrically connected to the body 10.

[0039] The cushion 26 is attached to the upper side of the main frame 21A and supports the buttocks of the occupant. The cushion 26 is made of an elastic material such as urethane, covered with a seat cover made of a resin sheet, leather, or the like. The backrest 27 is attached to the front side of the back frame 21B and supports the back of the occupant. When the back frame 21B rotates about the hinge 23, the reclining angle of the backrest 27 changes. Like the cushion 26, the backrest 27 is made of an elastic material such as urethane, covered with a seat cover made of a resin sheet, leather, or the like. As shown in FIG. 1, the seat cover on the rear surface of the backrest 27 covers the rear surface of the back frame 21B. Therefore, when the seat 20 is viewed from the rear of the vehicle, the seat cover on the rear side of the backrest 27 is visible. This seat cover on the rear side of the backrest 27 is referred to as a first seat cover 28.

[0040] As shown in Fig. 1, a sheet-like second seat cover 29 made of resin or leather is overlapped with a gap on the rear surface of a first seat cover 28 on the rear surface of a backrest 27. The gap between the first seat cover 28 and the second seat cover 29 forms a seat pocket 25. A vehicle static eliminator 30 is attached inside the seat pocket 25.

[0041] As shown in detail in part A in FIG. 1, vehicle static eliminator 30 is composed of flannel cloth 31 and PTFE sheet 32 ​​laminated on the rear of flannel cloth 31. Flannel cloth 31 is a cloth made of natural fibers with a zero potential in the triboelectric column, and constitutes a first zero potential member with a zero triboelectric potential. PTFE sheet 32 ​​is a sheet member made of polytetrafluoroethylene, a type of resin material. PTFE sheet 32 ​​constitutes a negatively charged member that is charged with negative static electricity due to sliding friction with flannel cloth 31.

[0042] Vehicle static eliminator 30 is sandwiched between first seat cover 28 and second seat cover 29 so that the vehicle front surface of flannel cloth 31 contacts first seat cover 28 and the vehicle rear surface of PTFE sheet 32 ​​contacts second seat cover 29. PTFE sheet 32 ​​is pressed against flannel cloth 31 by first seat cover 28 and second seat cover 29 so as to be frictionally slidable therebetween.

[0043] Next, the static elimination operation of the vehicle static eliminator 30 will be described with reference to Figures 2 and 3. The reason why the vehicle static eliminator 30 can eliminate positively charged static electricity from the body 10 has not been clearly elucidated, but is thought to be as follows. In the following description, it is assumed that the first seat cover 28 and the second seat cover 29 are both made of resin. Also, the arrows in Figure 3 indicate the polarity and magnitude of the electric potential at each location.

[0044] As shown in FIG. 2, when the vehicle 100 is traveling, the body 10 and the back frame 21B electrically connected to the body 10 are charged with positive static electricity. As a result, the body 10 and the back frame 21B assume a positive potential, as indicated by arrows 61 and 62 in FIG. 3. Furthermore, as the vehicle 100 is traveling, the PTFE sheet 32 ​​and the flannel cloth 31 rub against each other due to vibrations caused by traveling, etc. As a result, the PTFE sheet 32 ​​assumes a negative static charge, as indicated by arrows 65 and 66 in FIG. 3. Furthermore, the resin second seat cover 29 in contact with the PTFE sheet 32 ​​also assumes a negative potential, as indicated by arrow 67 in FIG. 3.

[0045] On the other hand, even when the flannel cloth 31 rubs against the PTFE sheet 32, the overall potential is maintained at zero. Therefore, as shown in FIG. 3, the laminate of the flannel cloth 31 and the first seat cover 28 generates induced polarization. As a result, the frictional sliding surface of the flannel cloth 31 with the PTFE sheet 32 ​​assumes a positive potential, as indicated by arrow 64 in FIG. 3. Furthermore, as indicated by arrow 63 in FIG. 3, the surface of the flannel cloth 31 facing the back frame 21B and the first seat cover 28 assume a negative potential. The negative static electricity indicated by arrow 63 and the positive static electricity of the back frame 21B indicated by arrow 62 in FIG. 3 are neutralized and eliminated, and the positive potential of the back frame 21B decreases by ΔV1, as indicated by arrow 69 in FIG. 3. Furthermore, the potential of the body 10, which is electrically connected to the back frame 21B, also decreases by ΔV2, as indicated by arrow 68 in FIG. 3. In this way, the vehicle static eliminator 30 neutralizes and eliminates the positive static electricity charged on the back frame 21B by using the negative static electricity generated on the PTFE sheet 32 ​​due to friction with the flannel cloth 31.

[0046] The vehicle static eliminator 30 reduces the positive potential charged to the body 10, thereby suppressing the potential of the body 10 from affecting the control system and sensors, thereby enabling the vehicle 100 to exhibit its inherent control performance. The vehicle static eliminator 30 has a simple configuration in which a flannel cloth 31 and a PTFE sheet 32 ​​are laminated together, and can be simply inserted into the seat pocket 25 of the seat 20 without requiring any modification of the components of the seat 20. Therefore, even if the vehicle 100 is a user-owned vehicle, static elimination of the body 10 can be easily performed.

[0047] In the vehicle static eliminator 30, the flannel cloth 31 may be disposed so that its entire surface is in contact with the first seat cover 28 and the PTFE sheet 32. In this case, the flannel cloth 31 is in contact with the back frame 21B via the first seat cover 28.

[0048] In the above description, the vehicle static eliminator 30 has been described as having a laminated structure of the flannel cloth 31 and the PTFE sheet 32, but the present invention is not limited to this. For example, in place of the flannel cloth 31, a cotton fabric or Japanese paper may be used as long as it is made of natural fibers with a zero potential in the triboelectric column. Furthermore, in place of the PTFE sheet 32, a sheet made of other resins, such as a polyester nonwoven fabric or a rayon nonwoven fabric, may be used as long as it is a negatively charged member that is charged with negative static electricity.

[0049] Next, a vehicle 110 equipped with a vehicle static eliminator 35 according to a second embodiment will be described with reference to Figures 4 and 5. The vehicle 110 is equipped with the vehicle static eliminator 35 instead of the vehicle static eliminator 30 of the vehicle 100 previously described with reference to Figures 1 to 3. The body 10, seats 20, and other components are the same as those of the vehicle 100. The same components as those of the vehicle 100 are designated by the same reference numerals and will not be described again.

[0050] As shown in Fig. 4, vehicle static eliminator 35 is made up of flannel cloth 31, PTFE sheet 32 ​​laminated on the rear side of flannel cloth 31, and flannel cloth 33 laminated on the rear side of PTFE sheet 32. Flannel cloth 33 is laminated on the surface of PTFE sheet 32 ​​opposite flannel cloth 31, and, like flannel cloth 31, is a cloth made of natural fibers with zero potential in the triboelectric potential table. Flannel cloth 33 constitutes a second zero potential member with a triboelectric potential of zero.

[0051] Flannel cloth 31 is disposed so that its surface facing the vehicle front is in indirect contact with back frame 21B via first seat cover 28. Flannel cloth 33 is disposed so that its surface facing the vehicle front (one surface) is laminated on the rear surface of PTFE sheet 32 ​​opposite back frame 21B, and its surface facing the vehicle rear (the other surface) is in contact with second seat cover 29. In this manner, vehicle static eliminator 35 is sandwiched between first seat cover 28 and second seat cover 29. PTFE sheet 32 ​​is pressed against flannel cloth 31 by first seat cover 28 and second seat cover 29 so as to be frictionally slidable therebetween.

[0052] Next, the static elimination operation of the vehicle static eliminator 35 will be described. The reason why the vehicle static eliminator 35 can eliminate positively charged static electricity from the body 10 has not been clearly elucidated, but is thought to be as follows. In the following explanation, it is assumed that the first seat cover 28 and the second seat cover 29 are both made of resin. Also, the arrows in Figure 5 indicate the polarity and magnitude of the electric potential at each location.

[0053] 3, frictional sliding between flannel cloth 31 and PTFE sheet 32 ​​and induced polarization generate negative potentials indicated by arrows 63 and 65 and positive potentials indicated by arrow 64 in flannel cloth 31 and PTFE sheet 32. Then, the negative static electricity indicated by arrow 63 and the positive static electricity of back frame 21B indicated by arrow 62 in FIG. 3 are neutralized and discharged, and the positive potential of body 10 and back frame 21B decreases as indicated by arrows 68 and 69 in FIG.

[0054] Furthermore, when the vehicle 110 is traveling, the PTFE sheet 32 ​​and the flannel cloth 33 rub against each other due to vibrations caused by traveling, etc. As a result, negative static electricity is charged to the PTFE sheet 32, as indicated by arrow 71 in FIGS. 4 and 5 . Like the flannel cloth 31, the flannel cloth 33 maintains a zero potential overall even when it rubs against the PTFE sheet 32. However, there is no positively charged component, such as the back frame 21B, on the rear side of the flannel cloth 33. Therefore, as shown in FIG. 5 , the flannel cloth 33 does not generate induced polarization, and the entire flannel cloth 33 maintains a zero potential, as indicated by the solid line 72 in FIG. 5 . This allows the flannel cloth 33 to prevent negative static electricity generated on the PTFE sheet 32 ​​from discharging to the outside from the second seat cover 29 side. The second seat cover 29 is made of resin, and friction with the flannel cloth 33, etc., causes a negative potential, as indicated by arrow 73 in FIG. 5 .

[0055] As described above, the vehicle static eliminator 35 has the flannel cloth 33 laminated on the rear surface of the PTFE sheet 32 ​​opposite the back frame 21B, thereby preventing negative static electricity generated on the PTFE sheet 32 ​​from discharging to the outside through the rear second seat cover 29. Therefore, the vehicle static eliminator 35 can efficiently neutralize the negative static electricity generated on the PTFE sheet 32 ​​with the positive static electricity charged on the back frame 21B. The vehicle static eliminator 35 can more effectively eliminate positive static electricity on the body 10 and reduce the potential of the body 10. Furthermore, the vehicle static eliminator 35 can more effectively prevent the potential of the body 10 from affecting the control system and sensors, allowing the vehicle 110 to exhibit its original control performance.

[0056] Next, with reference to Figure 6, a description will be given of a vehicle static eliminator 38, which is a variation of the vehicle static eliminator 35 described with reference to Figures 4 and 5, mounted on a vehicle 110. The vehicle static eliminator 38 has masking tape 34 attached to the peripheral edge of a PTFE sheet 32, and the peripheral edge of the PTFE sheet 32 ​​is laminated to flannel cloth 31 via the masking tape 34. This reduces the sliding friction area that generates negative static electricity, making it possible to adjust the potential of neutralization static elimination so that it approaches zero potential. The basic action / effect of the vehicle static eliminator 38 is the same as that of the vehicle static eliminator 35 described with reference to Figures 4 and 5.

[0057] Next, a vehicle 120 equipped with a vehicle static eliminator 39 according to a third embodiment will be described with reference to Fig. 7. The vehicle 120 is equipped with a vehicle static eliminator 39 instead of the vehicle static eliminator 35 of the vehicle 110 previously described with reference to Figs. 4 and 5. The body 10, seats 20, and other components are the same as those of the vehicles 100 and 110. The same components as those of the vehicles 100 and 110 are designated by the same reference numerals, and description thereof will be omitted.

[0058] 7, vehicle static eliminator 39 is made by laminating flannel cloth 31 and PTFE sheet 32, and attaching PP sheet 37, which is an antistatic resin member, to the rear surface of PTFE sheet 32 ​​with silicone adhesive material 36. PP sheet 37 is laminated on the surface of PTFE sheet 32 ​​opposite to back frame 21B.

[0059] The PP sheet 37 is a resin sheet made of antistatic polypropylene, and the silicone adhesive 36 has a static-removing effect. The PP sheet 37 is laminated on the surface of the PTFE sheet 32 ​​opposite the back frame 21B, thereby preventing negative static electricity generated on the PTFE sheet 32 ​​from discharging to the outside from the second seat cover 29 opposite the back frame 21B. Therefore, the vehicle static eliminator 39 can efficiently neutralize the negative static electricity generated on the PTFE sheet 32 ​​with the positive static electricity charged on the back frame 21B. This allows the vehicle static eliminator 39 to more effectively remove positive static electricity from the body 10 and reduce the potential of the body 10.

[0060] Next, a vehicle 130 according to another embodiment will be described with reference to Fig. 8. A seat 220 of the vehicle 130 is provided with a retractable armrest 40. The armrest 40 rotates as indicated by arrow 91 in Fig. 8 and is stored in a recess 41 provided in the backrest 27. Other configurations of the seat 220 are the same as those of the seat 20 described with reference to Fig. 1, and therefore will not be described again.

[0061] As shown in detail in part B in FIG. 8, a resin bottom cover 42 is attached to the bottom surface of the recess 41 or the surface on the vehicle rear side. The bottom cover 42 covers the outer surface of the back frame 21B facing forward. The vehicle static eliminator 35 described with reference to FIGS. 4 and 5 is disposed on the vehicle front side of the bottom cover 42. The flannel cloth 31 of the vehicle static eliminator 35 contacts the back frame 21B via the bottom cover 42. The flannel cloth 33 facing forward of the vehicle static eliminator 35 is covered by a resin front cover 43. The PTFE sheet 32 ​​is sandwiched between the flannel cloths 31 and 33. The peripheral edge of the front cover 43 is fixed to the surface of the bottom cover 42, bringing the PTFE sheet 32 ​​into frictional and slidable pressure contact with the flannel cloth 31.

[0062] The vehicle static eliminator 35 attached to the vehicle 130 neutralizes the negative static electricity charged to the PTFE sheet 32 ​​and the positive static electricity charged to the back frame 21B by frictional sliding between the flannel cloth 31 and the PTFE sheet 32 ​​and induced polarization. This reduces the positive potential of the back frame 21B and the body 10.

[0063] Next, a configuration in which the vehicle static eliminator 35 is mounted in a box 47 of the vehicle 130 will be described with reference to Fig. 9. As shown in Fig. 9, the box 47 is provided adjacent to the seat 20 in the vehicle 130. As shown in the CC cross section in Fig. 9, the right side of the box 47 is disposed adjacent to the left side surface of the back frame 21B.

[0064] A first side cover 48 made of resin is attached to the right side surface inside the box 47. The first side cover 48 covers the vehicle left side surface of the back frame 21B. The vehicle static eliminator 35 described with reference to Figures 4 and 5 is disposed on the vehicle left side surface of the first side cover 48. The flannel cloth 31 of the vehicle static eliminator 35 contacts the side surface of the back frame 21B via the first side cover 48. The flannel cloth 33 on the vehicle left side of the vehicle static eliminator 35 is covered with a second side cover 49 made of resin. The PTFE sheet 32 ​​is sandwiched between the flannel cloths 31 and 33. The peripheral edge of the second side cover 49 is fixed to the surface of the first side cover 48, bringing the PTFE sheet 32 ​​into frictional and slidable pressure contact with the flannel cloth 31.

[0065] The operation and effect of the vehicle static eliminator 35 shown in FIG. 9 are the same as those of the vehicle static eliminator 35 described with reference to FIG.

[0066] Next, a vehicle 140 according to another embodiment will be described with reference to Fig. 10. The vehicle 140 has the vehicle static eliminator 35 described with reference to Figs. 4 and 5 attached to the rear lower side of the seat back 27 of the vehicle 100 described with reference to Fig. 1. Note that the second seat cover 29 and the seat pocket 25 are not shown in Fig. 10.

[0067] As shown in detail in portion D in FIG. 10 , a vehicle static eliminator 35 is disposed on the vehicle rear surface of first seat cover 28. Flannel cloth 31 of vehicle static eliminator 35 contacts back frame 21B via first seat cover 28. Flannel cloth 33 on the vehicle rear side of vehicle static eliminator 35 is covered with a resin rear cover 45. PTFE sheet 32 ​​is sandwiched between flannel cloth 31 and flannel cloth 33. The peripheral edge of rear cover 45 is fixed to the surface of first seat cover 28, bringing PTFE sheet 32 ​​into frictionally slidable pressure contact with flannel cloth 31.

[0068] The vehicle static eliminator 35 attached to the vehicle 140, like the vehicle static eliminator 35 attached to the vehicle 130, neutralizes and eliminates negative static electricity charged to the PTFE sheet 32 ​​and positive static electricity charged to the back frame 21B through frictional sliding between the flannel cloth 31 and the PTFE sheet 32 ​​and induced polarization.

[0069] Next, a vehicle 150 according to another embodiment will be described with reference to Fig. 11. Components similar to those of the vehicle 100 previously described with reference to Fig. 1 will be assigned the same reference numerals and description thereof will be omitted.

[0070] As shown in FIG. 11 , a vehicle 150 has a vehicle static eliminator 35 attached to the underside of the main frame 21A of the vehicle 100 described with reference to FIG. 1 . As shown in detail in part E of FIG. 11 , the upper flannel cloth 31 of the vehicle static eliminator 35 is in direct contact with the main frame 21A. The lower flannel cloth 33 of the vehicle static eliminator 35 is laminated on the underside of the PTFE sheet 32 ​​on the side opposite the main frame 21A. The PTFE sheet 32 ​​is sandwiched between the flannel cloths 31 and 33. The outside of the flannel cloth 33 is covered with an outer cover 46. The peripheral edge of the outer cover 46 is fixed to the surface of the main frame 21A, pressing the vehicle static eliminator 35 against the main frame 21A and bringing the PTFE sheet 32 ​​into frictionally and slidably pressure contact with the flannel cloth 31.

[0071] The vehicle static eliminator 35 attached to the vehicle 150, like the vehicle static eliminators 35 attached to the vehicles 130 and 140, neutralizes and eliminates negative static electricity charged to the PTFE sheet 32 ​​and positive static electricity charged to the main frame 21A and the body 10 through frictional sliding between the flannel cloth 31 and the PTFE sheet 32 ​​and induced polarization.

[0072] In the vehicle static eliminator 35, the entire surface of the flannel cloth 31 may be in direct contact with the main frame 21A.

[0073] Next, a vehicle 160 according to another embodiment will be described with reference to Fig. 12. Vehicle 160 is configured such that antistatic agents 51, 52 are applied to the surfaces of cushion 26 and backrest 27 of seat 20 of vehicle 100 described with reference to Fig. 1.

[0074] As explained above with reference to Figure 1, the cushion 26 and backrest 27 of the seat 20 are made by covering the surface of an elastic material such as urethane with a seat cover made of a resin sheet, leather, or the like. Antistatic agents 51, 52 are applied to the seating surface of the surface of seat cover 26A on the upper side of cushion 26 on which the occupant sits, and to the backrest surface of seat cover 27A on the front side of backrest 27 that supports the occupant's back, respectively. Here, seat covers 26A, 27A form the surfaces of cushion 26 and backrest 27, respectively.

[0075] In this way, applying antistatic agents 51, 52 to the seating surfaces and backrest surfaces of seat covers 26A, 27A that come into contact with the occupant prevents static buildup on seat covers 26A, 27A and suppresses unstable electrostatic induction between the occupant and back frame 21B or between the occupant and main frame 21A. This stabilizes the induced polarization of flannel cloth 31 between back frame 21B and PTFE sheet 32 ​​shown in Figures 3 and 5, and allows the potential of back frame 21B to be steadily reduced to approximately zero.

[0076] Various types of antistatic agents 51, 52 can be used here, but using the appropriate agent depending on the material of the seat covers 26A, 27A can effectively prevent static buildup in the seat covers 26A, 27A. For example, if the seat covers 26A, 27A are made of a synthetic resin material that is on the negative side of the triboelectric electrification table, such as a nonwoven synthetic resin fabric fiber or synthetic leather made of a synthetic resin with fine irregularities, it is effective to apply antistatic agents 51, 52 containing a cationic surfactant. Also, if the seat covers 26A, 27A are made of a leather material that is on the positive side of the triboelectric electrification table, such as genuine leather with fine irregularities, it is effective to apply antistatic agents 51, 52 containing a fluororesin agent.

[0077] As described above, the vehicle static eliminators 30, 35, 38, and 39 of the embodiments can effectively eliminate positively charged static electricity on the vehicles 100, 110, 120, 130, 140, 150, and 160. This allows the vehicle static eliminators 30, 35, 38, and 39 to exhibit the inherent control performance of the vehicles 100, 110, 120, 130, 140, 150, and 160. Furthermore, the vehicle static eliminators 30, 35, 38, and 39 have a simple configuration in which the flannel cloth 31 and the PTFE sheet 32 ​​are laminated together, and there is no need to change the surface material of the seat 20 member. Therefore, the vehicle static eliminators 30, 35, 38, 39 can be easily attached even when the vehicles 100, 110, 120, 130, 140, 150, 160 are owned by users, and static elimination of the body 10 can be easily performed.
