Description

[Technical field]

[0001] The present invention relates to a vehicle interior member, and more particularly to a vehicle interior member equipped with a heating device. [Background technology]

[0002] Generally, various automobiles such as passenger cars are provided with a console box between the front seats (driver's seat and passenger seat) as a vehicle interior component capable of storing personal items in a removable manner. This console box includes a console main body, which is a main body in which an item storage section for storing various items is defined, and a lid member, which is an opening / closing member that is supported by a support mechanism at the rear upper part of the main body and opens and closes the upper opening of the item storage section. Since such a console box is located to the side of the front seats, in many cases, the upper surface portion of the lid member is adjusted and installed at a height suitable for use as an armrest (for example, Patent Document 1).

[0003] [Patent Document 1] JP 2013-241040 A Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, as in Patent Document 1, there is a heating device for cold weather in which a nichrome wire heater is built into the cover member of a console box or a steering wheel, so that the driver's hands and fingers can be directly warmed. However, such a heating device is limited in the places where it can be installed due to its poor conformability, and when it is installed in a part having cushioning properties, it has a problem of a foreign body feeling being prominent and a poor usability. In addition, many automobiles are equipped with an air conditioner or other air conditioning device as a heating device, and are configured to keep the passenger compartment at an appropriate temperature in cold weather. However, such air conditioners and heating devices such as nichrome wire heaters consume a lot of power. For this reason, such heating devices can be used without problems in automobiles that use an internal combustion engine (engine) that burns fuel such as gasoline as a power source as in the past, but in automobiles that use an electric motor (motor) alone or in combination as a power source, such as electric vehicles and hybrid vehicles, the power available for the heating device is limited, and its use may be restricted.

[0005] Therefore, in consideration of the above-mentioned problems inherent in the conventional technology, the present invention has been proposed to optimally solve these problems, and aims to provide a vehicle interior component equipped with a heating device that has a high degree of freedom in terms of installation location and reduces power consumption. [Means for solving the problem]

[0006] In order to solve the above problems and achieve the intended object, the first invention provides: A vehicle interior member configured to cover a surface of a foam having cushioning properties with a skin material, an insulating flexible base sheet; a plurality of wiring patterns formed on the base sheet and connected to a power supply device, the wiring patterns being separated from one another; a heating portion having a PTC characteristic formed on the base sheet so as to connect the plurality of wiring patterns; The present invention relates to a film heating element having a film heating element and a film heating element having a film heating element. In this way, by providing a film heating element having a wiring pattern and a heating part on a flexible base sheet between the foam and the skin as a heating device, the film heating element can easily deform following the deformation of the foam, and can effectively heat while maintaining a good usability. In other words, the heating device can be suitably installed even in vehicle interior parts that require cushioning, where it was previously difficult to install a heating device. In addition, since the heating part has PTC characteristics, it is possible to autonomously prevent excessive temperature rise without providing a temperature sensor such as a thermostat or a controller for temperature control, and to suppress power consumption.

[0007] The second invention is The multiple wiring patterns are formed in a comb shape having a pattern base line extending in a predetermined direction and branch pattern lines arranged at predetermined intervals in the extension direction of the pattern base line, and are configured such that branch pattern lines of a predetermined wiring pattern are positioned between the branch pattern lines of another wiring pattern. In this way, by forming the wiring pattern of the film heating element in a comb-like shape, the distance between the wiring patterns can be set short, improving electrical conductivity of the heating portion and improving heat generation of the heating portion.

[0008] The third invention is The base sheet is made of a thermoplastic elastomer sheet, and a wiring pattern is printed on the base sheet using silver paste, and a heat generating portion is printed on the base sheet using carbon paste. In this way, by forming a film heating element using a thermoplastic elastomer sheet as the base sheet, the film heating element itself has flexibility, making it comfortable to the passenger when touching it.

[0009] The fourth invention is The film heating element includes a connection wiring portion that is connected to the wiring pattern, A power supply wiring for connecting to a power supply device is provided on the back side of the base material supporting the foam body, The skin material covering the surface of the foam is fixed by wrapping an end of the skin material around the back side of the base material, and a terminal of the connection wiring portion extending from the end of the skin material wrapped around the back side of the base material is connected to the power supply wiring. In this way, by making the connection wiring of the film heating element extend from the end of the skin material wrapped around the back side of the base material, the connection wiring can be easily connected to the power supply wiring on the back side of the base material. Also, since the film heating element provided between the foam and the skin material can be connected to the power supply wiring without processing such as drilling holes in the foam or base material, the cushioning properties of the foam are not lost and a good usability can be achieved. Effect of the Invention

[0010] According to the present invention, the degree of freedom in the installation location is high and power consumption can be reduced. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Next, a vehicle interior member according to the present invention will be described below by way of a preferred embodiment with reference to the accompanying drawings. In the embodiment, as shown in FIG. 1(a), a console box 10 is illustrated as an example of the vehicle interior member, which is installed between the front seats (driver's seat and passenger seat) S, S in the passenger compartment of a vehicle. In addition, in the console box 10 of the embodiment, the front and rear refer to the front-to-rear direction of the vehicle when installed in the vehicle, and the left and right refer to the left and right directions based on the forward direction of the vehicle. In FIG. 1, the lower left side of the figure is the front side of the vehicle, and the upper right side of the figure is the rear side of the vehicle.

[0013] 1, a console box 10 according to the embodiment includes a box body 12 defining a storage section 14 inside thereof for storing personal items such as glasses, and a lid member 20 disposed on the upper part of the box body 12. In the console box 10, the rear side of the lid member 20 is rotatably supported by a support mechanism (not shown) provided on the rear side of the box body 12, and the lid member 20 is rotatable relative to the box body 12 with the support mechanism serving as a rotation fulcrum. The console box 10 is configured so that an opening 16 of the storage section 14, which opens at the top of the box body 12, can be opened and closed by rotating and displacing the lid member 20.

[0014] As shown in FIG. 2, the lid member 20 includes a base material 22 that serves as a framework for ensuring the rigidity of the lid member 20, a foam 24 provided on the upper surface of the base material 22, and a skin material 26 that covers the outer surface of the foam 24. The base material 22 also includes a cover member 28 (see FIG. 1(b)) on the lower surface that faces the storage section 14, and the lower surface of the lid member 20 that is visible from the outside when the lid member 20 is opened is decorated with the cover member 28 to maintain a good appearance. The base material 22 and the cover member 28 are made of synthetic resin or the like by injection molding or the like. The foam 24 is a member provided on the upper surface of the base material 22 and forms the outer shape of the lid member 20, and is made of a flexible material having elasticity such as soft urethane foam. The foam 24 is fixed to the upper surface of the base material 22 by adhering it with an adhesive such as hot melt as a fixing means. The means for fixing the foam 24 to the base material 22 is not limited to adhesive, and any of the various conventionally known means may be used.

[0015] The skin material 26 is a member that covers the outer surface of the foam 24 to give the appearance of the lid member 20, and is formed by sewing a skin base material made of synthetic leather, fabric, leather, etc., formed of synthetic resin materials such as polyurethane and polyvinyl chloride, and is formed into a bag shape that can be placed over the foam 24 fixed to the base material 22 from above and contained therein. As shown in FIG. 4(b), this skin material 26 is formed so that an end of the skin material 26 extends below the foam 24 when placed over the foam 24 from above, and the end of the skin material 26 that is wrapped around the lower surface side of the base material 22 is fixed by adhering it to the lower surface of the base material 22 with an adhesive such as hot melt as a fixing means. That is, the end of the skin material 26 is accommodated in the space between the lower surface of the base material 22 and the cover member 28, and the end of the skin material 26 is not exposed to the outside when the lid member 20 is opened, so that a good appearance is maintained. The means for fixing the ends of the skin material 26 to the base material 22 is not limited to adhesive, but may be a hook-shaped engaging portion, fastener, or the like, and various means known in the art may be used.

[0016] As shown in FIG. 1, an operating section 30 is provided at the approximate center of the front side of the lid member 20, and a storage space 34 is defined in the base material 22 so as to open forward in correspondence with the mounting position of the operating section 30. The operating section 30 is always biased forward by a biasing member (not shown) such as a spring, and a first engagement section 32 is provided at the bottom of the operating section 30. A second engagement section 18 is provided on the front upper surface of the box body 12, which engages with the first engagement section 32 provided on the operating section 30 when the lid member 20 is closed, and the first engagement section 32 and the second engagement section 18 are engaged to hold the lid member 20 in a closed state. By pressing the operating section 30 backward, the engagement between the first engagement section 32 and the second engagement section 18 is released, and the lid member 20 is allowed to be opened.

[0017] 1, 2, and 4, the cover member 20 is provided with a film heating element 40 between the foam 24 and the skin material 26. As shown in FIG. 3, the film heating element 40 includes wiring patterns 44, 46 formed on a flexible base sheet 42, and a heating portion 48 formed on the base sheet 42 to connect to the wiring patterns 44, 46, and is configured so that the heating portion 48 generates heat by passing electricity through the wiring patterns 44, 46. In this embodiment, a first wiring pattern 44 connected to one electrode (positive electrode) and a second wiring pattern 46 connected to the other electrode (negative electrode) are formed on one side of the base sheet 42, and the first wiring pattern 44 and the second wiring pattern 46 are configured to be connected by the heating portion 48. It is preferable to configure the wiring patterns 44, 46 and the heating portion 48 formed on the base sheet 42 to be covered with an insulating film 50 equivalent to the base sheet 42. In the following description, the surface of the base sheet 42 on which the wiring patterns 44, 46 and the heat generating portion 48 are formed is referred to as the front surface, and the opposite surface is referred to as the back surface. The back surface of the base sheet 42 is fixed to the upper surface of the foam 24 or the inner surface of the skin material 26 facing the foam 24 using a fixing means such as an adhesive, and the foam 24 in this state is covered with the skin material 26 so that the film heat generating element 40 is located between the foam 24 and the skin material 26. The position of the film heat generating element 40 relative to the foam 24 is not particularly limited, but in this embodiment, it is located at a position biased toward the front side of the upper surface of the foam 24, approximately in the center from left to right.

[0018] Here, as the base sheet 42, a flexible insulating film such as polyethylene terephthalate can be used, but preferably a rubber-like resin sheet capable of deforming in accordance with the elastic deformation of the foam 24 is used. In particular, a thermoplastic elastomer sheet formed from a thermoplastic elastomer (TPE) having rubber elasticity at room temperature, such as an amide-based thermoplastic elastomer, an ester-based thermoplastic elastomer, an olefin-based thermoplastic elastomer (TPO), a styrene-based thermoplastic elastomer (TPS), or a urethane-based thermoplastic elastomer (TPU), is preferred. The base sheet 42 can be formed in any shape, but in this embodiment, the base sheet 42 is formed in a thick T-shape with strip-like extensions 42b, 42b extending from both sides of a rectangular main body 42a, the main body 42a forming the heat generating portion 48, and the extensions 42b, 42b forming the connection wiring portions 52, 54 described later. The thickness of the base sheet 42 is not particularly limited, but a thickness of 1 mm or less provides excellent flexibility and a comfortable feel when touched by an occupant.

[0019] Each of the first wiring pattern 44 and the second wiring pattern 46 is formed by screen printing a conductive paste such as silver paste on the base sheet 42. As shown in Fig. 3, the first wiring pattern 44 is formed in a comb shape having a first pattern base line 44a extending linearly along one edge portion (the left edge portion in Fig. 3(a)) of the main body portion 42a of the base sheet 42 and a plurality of first branch pattern lines 44b provided at predetermined intervals in the extending direction of the first pattern base line 44a and extending toward the other edge portion (the right edge portion in Fig. 3(a)) of the base sheet 42, and is configured so that a first connection wiring portion 52 described later is connected to an end portion of the first pattern base line 44a. Similarly, as shown in FIG. 3, the second wiring pattern 46 is formed in a comb-like shape having a second pattern base line 46a extending in a straight line along the other edge portion (the right edge portion in FIG. 3(a)) of the main body portion 42a of the base sheet 42, and a plurality of second branch pattern lines 46b arranged at predetermined intervals in the extension direction of the second pattern base line 46a and extending toward one edge portion (the left edge portion in FIG. 3(a)) of the base sheet 42, and is configured so that a second connection wiring portion 54 described later is connected to the end portion of the second pattern base line 46a.

[0020] The first wiring pattern 44 and the second wiring pattern 46 are formed in the main body portion 42a of the base sheet 42 at a predetermined distance so that the first wiring pattern 44 and the second wiring pattern 46 are not in contact with each other, and are formed in a staggered manner such that the second branch pattern lines 46b are located between the first branch pattern lines 44b. A heat generating portion 48 is provided in the main body portion 42a of the base sheet 42 so as to fill the space between the first wiring pattern 44 and the second wiring pattern 46, and the first wiring pattern 44 and the second wiring pattern 46 are connected via the heat generating portion 48.

[0021] The heat generating section 48 is formed of a material having a positive temperature characteristic (a characteristic in which resistance increases as temperature rises: PTC (positive temperature coefficient)), and is configured so that the resistance value increases as the temperature rises due to self-heating caused by current flow, and the heat generating temperature is adjusted autonomously by suppressing the current. The heat generating section 48 having such PTC characteristics can be formed by dispersing conductive particles such as carbon particles in urethane resin, polyolefin resin, or the like. In this embodiment, the heat generating section 48 is formed by screen printing a carbon ink (carbon paste) containing carbon particles, urethane resin, and wax as main components onto the base sheet 42 to form a film. Here, if the carbon particle content in the heat generating section 48 exceeds 60% by weight, it becomes difficult to exhibit the PTC characteristic, so it is preferable that the carbon particles are in the range of 20 to 60% by weight, the urethane resin is in the range of 20 to 50% by weight, and the wax is in the range of 10 to 30% by weight. The thickness of the wiring patterns 44, 46 and the heat generating section 48 is not particularly limited, but can be formed to be 7 to 10 μm.

[0022] The heat generating portion 48 of the embodiment is formed on the entire area on the main body 42a of the base sheet 42 where the first wiring pattern 44 and the second wiring pattern 46 are not formed. In FIG. 3, the area where the heat generating portion 48 is formed is shown by a dot pattern. The heat generating portion 48 may be formed so as to overlap the area where the first wiring pattern 44 and the second wiring pattern 46 are formed, for example, the heat generating portion 48 may be formed on the entire surface of the base sheet 42 where the first wiring pattern 44 and the second wiring pattern 46 are formed. In this way, by increasing the formation area of ​​the heat generating portion 48, the heat generating area is increased, which is more preferable. Here, the heat setting temperature by the heat generating portion 48 (for example, 60°C, 80°C) can be easily adjusted by changing the first wiring pattern 44 and the second wiring pattern 46, the amount of conductive material of the heat generating portion 48, the film thickness of the heat generating portion 48 when printed, etc.

[0023] The film heating element 40 of the embodiment includes a strip-shaped first connection wiring portion 52 that extends from one edge of the main body portion 42a of the base sheet 42 and connects to the first wiring pattern 44, and a strip-shaped second connection wiring portion 54 that extends from the other edge of the base sheet 42 and connects to the second wiring pattern 46. Here, the connection wiring portions 52, 54 can be configured in the same configuration as the first wiring pattern 44 and the second wiring pattern 46. That is, they can be configured by forming a conductive paste material such as silver paste on the extension portion 42b extending from the main body portion 42a of the base sheet 42 by screen printing. By configuring in this way, it is possible to efficiently form each connection wiring portion 52, 54 and each wiring pattern 44, 46 by a single printing process.

[0024] Here, as shown in Fig. 4(a), the connection wiring parts 52, 54 are formed so that the terminals of the connection wiring parts 52, 54 extend below the foam 24 when the connection wiring parts 52, 54 are laid in close contact with the upper surface of the foam 24 to which the base sheet 42 is fixed. The connection wiring parts 52, 54 are formed to a length that extends (exposes) outward beyond the terminal of the skin material 26 that is placed over the foam 24, and the connection wiring parts 52, 54 can be wrapped around the lower surface of the base material 22 at the same time that the terminal of the skin material 26 is wrapped around and fixed to the lower surface of the base material 22. That is, the terminals of the connection wiring parts 52, 54 are accommodated in the space between the lower surface of the base material 22 and the cover member 28, and the terminals of the connection wiring parts 52, 54 are not exposed to the outside when the lid member 20 is opened, thereby maintaining a good appearance. Further, a power supply wiring 60 that is connected to a power supply device provided in a vehicle is attached to the lower surface of the base material 22, and each of the connection wiring parts 52, 54 exposed on the lower surface side of the base material 22 is configured to be connected to the power supply wiring 60. In this manner, by wrapping each of the connection wiring parts 52, 54 together with the skin material 26 on the lower surface side of the base material 22 in a state where the connection wiring parts 52, 54 are extended (exposed) outward from the end of the skin material 26, it becomes possible to extremely easily perform the connection work with the power supply wiring 60 arranged on the back side of the base material 22. Here, the power supply wiring 60 is provided so as to extend in the front-rear direction on the lower surface of the base material 22, and is configured to be routed from the rear side of the base material 22, where the support mechanism that rotatably supports the lid member 20 is located, to the box body 12 side.

[0025] Next, the operation of the vehicle interior member according to the present embodiment will be described. As shown in Fig. 4(a), the foam 24 is fixed to the upper surface of the base material 22 by bonding with an adhesive as a fixing means such as hot melt, and the base sheet 42 of the film heating element 40 is fixed to the upper surface of the foam 24 by using a fixing means such as adhesive. At this time, the connection wiring parts 52, 54 of the film heating element 40 are made to run along the upper surface of the foam 24, and the terminals of the connection wiring parts 52, 54 are extended downward from the foam 24, and the skin material 26 is covered from above the foam 24 (Fig. 4(b)). In this state, the terminals of the skin material 26 extending downward from the foam 24 and the terminals of the connection wiring parts 52, 54 are wrapped around the lower surface side of the base material 22, and the terminals of the skin material 26 are bonded and fixed to the lower surface of the base material 22 by an adhesive as a fixing means such as hot melt (Fig. 4(c)). Then, the connection wiring parts 52, 54 extending (exposed) outward beyond the terminal of the skin material 26 are connected to the power supply wiring 60 provided on the underside of the base material 22, and then the cover member 28 is attached to the underside of the base material 22, thereby forming the lid member 20 of the console box 10 having the film heating element 40 between the foam 24 and the skin material 26 (FIG. 4(d)). Note that the mounting structure of the cover member 28 to the base material 22 may employ any conventionally known configuration, but in FIG. 4, the cover member 28 is attached to the underside of the base material 22 by fitting the engaging protrusion 22a formed on the underside of the base material 22 into the mounting hole 28a formed in the cover member 28.

[0026] In this way, by making the connection wiring parts 52, 54 of the film heating element 40 extend from the end of the skin material 26 wrapped around the back side of the base material 22, the connection wiring parts 52, 54 can be easily connected to the power wiring 60 on the back side of the base material 22. In addition, when the film heating element 40 is provided between the foam 24 and the skin material 26, wiring connection to the film heating element 40 can also be realized by performing processing such as forming perforations for wiring insertion at appropriate positions of the foam 24 or the base material 22. In this case, the cushioning properties of the foam 24 before and after processing may change due to processing such as perforation on the foam 24 or the base material 22, and depending on the position of the perforation, the repulsive force of the foam 24 may decrease, leading to a loss of cushioning properties. In contrast, in this embodiment, the film heating element 40 provided between the foam 24 and the skin material 26 can be connected to the power wiring 60 without performing processing such as forming perforations on the foam 24 or the base material 22, so that the cushioning properties of the foam 24 are not lost and a good usability can be achieved.

[0027] By providing the film heating element 40, which has wiring patterns 44, 46 and a heating portion 48 on a flexible base sheet 42, between the foam 24 and the skin 26 as a heating device, heat is easily transferred to the hands of the occupant who touches the cover member 20 of the console box, and the film heating element 40 can easily deform in accordance with the deformation of the foam 24 due to the contact. That is, even for the cover member 20 of the console box, which requires cushioning and for which it was previously difficult to install a heating device, the heating device (film heating element 40) can be suitably installed while maintaining a good usability and effectively heat it. In addition, since the heating portion 48 of this film heating element 40 has a PTC characteristic, it is possible to autonomously prevent excessive temperature rise without providing a temperature sensor such as a thermostat or a controller for temperature control, and to suppress the amount of power consumption.

[0028] In addition, by forming the wiring patterns 44, 46 of the film heating element 40 in a comb-like shape and arranging the first branch pattern lines 44b of the first wiring pattern 44 and the second branch pattern lines 44b of the second wiring pattern 46 in an alternating manner, it is possible to shorten the distance between the wiring patterns 44, 46. This improves the electrical conductivity of the heat generating portion 48 and improves the heat generating property of the heat generating portion 48.

[0029] Furthermore, by using a thermoplastic elastomer sheet for the base sheet 42 of the film heating element 40, the film heating element 40 itself has flexibility, making it possible to improve the feeling of use when touched by an occupant.

[0030] (Example of change) The vehicle interior member according to the present invention is not limited to the above-described embodiment, but may be modified in various ways. (1) In the present embodiment, the back surface of base sheet 42 of film heater 40 is attached to the upper surface of foam 24, but the back surface of base sheet 42 of film heater 40 may be attached to the inner surface of skin 26 that faces foam 24, and skin 26 with film heater 40 attached may be placed over foam 24. (2) In this embodiment, the film heating element 40 is provided on the lid member 20 that is provided to be able to be opened and closed on the console box 10 that is installed in the passenger compartment as a vehicle interior component. However, the lid member 20 may be a front-rear sliding type. (3) In the present embodiment, the console box 10 installed in the passenger compartment is exemplified as a vehicle interior component, but the present invention is not limited thereto, and can be suitably adopted for vehicle interior components that may come into contact with a passenger in the vehicle. For example, the console box 10 may be provided on the seat surface or backrest of the seat on which the passenger sits, or may be adopted for an armrest supported by the backrest. Furthermore, the console box 10 can be suitably adopted for a door trim installed in a door panel or a glove box in an instrument panel. (4) In this embodiment, the wiring patterns 44, 46 of the film heating element 40 are formed in a comb-like shape, but this is not limited to this and the wiring patterns 44, 46 may be formed in any shape. (5) In this embodiment, the film heating element 40 is formed in a thick T-shape with strip-shaped extensions 44b, 44b extending from both sides of the rectangular main body 44a, but the shape of the film heating element 40 is not limited to this. For example, the base sheet 42 may be formed in a rectangular shape, and the first wiring pattern 44, the second wiring pattern 46, and the heating portion 48 may be formed in an area spaced from the outer periphery on the base sheet 42 to provide a heating area, and the first connection wiring portion 52 and the second connection wiring portion 54 may be formed in an area outside the heating area on the base sheet 42 to connect to the first wiring pattern 44 and the second wiring pattern 46. In this case, the base sheet 42 is formed so that the area outside the heating area extends (exposed) outward from the end of the skin material 26 placed over the foam 24, and is configured so that the area outside the heating area can be wrapped around the lower surface side of the substrate 22 together with the skin material 26. In this example, there is an area on the base sheet 42 where the wiring patterns 44, 46, the heat generating portion 48, and the connection wiring portions 52, 54 are not arranged (areas outside the heat generating area).
