[0017] Hereinafter, an embodiment of the present invention will be described with reference to FIGS. This embodiment relates to an invention of a vehicle interior part (vehicle door lining) that is attached to a vehicle, and includes a light-emitting member that emits light toward the inside of the vehicle, a power generating member that is electrically connected to the light-emitting member and supplies electricity to the light-emitting member, and a storage member that is electrically connected to the light-emitting member and the power generating member and stores electricity, the main feature of which is that the power generating member is sheet-shaped or film-shaped and is arranged along the surface of the door lining. In addition to vehicle interior accessories, there are also inventions relating to vehicle seats. In addition, "vehicle fore-and-aft direction (front-and-aft direction)" refers to the fore-and-aft direction when the vehicle is normally driving, and "vehicle width direction (inner side of the vehicle)" refers to the interior side of the vehicle relative to the vehicle door.

[0018] <First embodiment of vehicle door lining> First, a vehicle door lining 1 (hereinafter also referred to as a door lining) according to a first embodiment will be described with reference to Figs. 1 to 8F. As shown in Figures 1 and 2, the vehicle door lining 1 is a vehicle interior part that decorates the interior side of a vehicle door D, and is composed of a group of parts that are attached to a door panel D1 that serves as the base plate of the vehicle door D. For example, as shown in FIG. 2, the door lining 1 includes an armrest 2 for supporting the arms of a seated occupant, an operating handle 3 for opening and closing a vehicle door D, which is located above the front portion of the armrest 2, a pocket portion 4 which is located below the front portion of the armrest, and an operating panel 5 which is located on the upper surface of the armrest 2 and which is used to adjust the opening and closing of a power window.

[0019] As shown in FIG. 1, the door panel D1 is mainly composed of an outer panel D2 and an inner panel D3 which are made of steel plates. A reinforcing member D4 is formed on the inner surface of the inner panel D3, and extends longitudinally in the seat front-rear direction. Further reinforcing members may be formed on the inner surface of the outer panel D2 and the outer surface of the inner panel D3. The reinforcing member D4 has, for example, a groove shape in vertical cross section and forms a closed cross-sectional structure together with the main body of the inner panel D3 as shown in Fig. 1. Also, the reinforcing member D4 extends from the front end portion of the door lining 1 toward the rear end portion while slanting downward as shown in Fig. 3.

[0020] As shown in FIGS. 2 to 4, the door lining 1 is configured by covering a door lining base material 10, which serves as a substrate of the door lining 1, with a skin material 20. The door lining 1 has a front end portion of the door lining base material 10 rotatably attached to the vehicle body via a hinge 10a. Therefore, connection members for various electric components provided in the door lining 1 extend toward the front end portion of the door lining 1. The connection members are connected to a power source (power supply system) provided in the vehicle body.

[0021] In order to provide lighting within the vehicle, the door lining 1 is equipped with a lighting module including an illuminating member 30 that emits light toward the inside of the vehicle, a decorative panel 40 that is illuminated by the illuminating member 30, a power generating member 50 that supplies electricity to the illuminating member 30, a storage member 60 that stores electricity, and a connecting member 70 that electrically connects the illuminating member 30, the decorative panel 40, the power generating member 50, and the storage member 60. Furthermore, the door lining 1 is electrically connected to the light emitting member 30, the decorative panel 40, the power generating member 50 and the electricity storing member 60 via a connecting member 70, and includes a controller 80 that controls the light emission of the light emitting member 30. The light emitting member 30, the decorative panel 40, the power generating member 50, the power storage member 60 and the controller 80 are attached to the door lining base material 10 at predetermined positions.

[0022] As shown in Figs. 1, 3 and 4, the door lining base material 10 is a plate-shaped frame made of resin, and extends long in the front-rear direction of the vehicle. The door lining base material 10 is formed on its inner side surface of the vehicle and is equipped with an armrest base material portion 11 which serves as the base material portion of the armrest 2, an assembly portion 12 which is formed at a position above the armrest base material portion 11 and is used to assemble the light-emitting member 30 and the decorative panel 40, and an impact absorbing portion 13 which is formed on the outer side surface of the door lining base material 10 and is positioned below the armrest base material portion 11 and protrudes toward the door panel D1.

[0023] The mounting portion 12 is formed as a substantially rectangular recess, and a light emitting member 30 is attached to the bottom of the mounting portion 12, and a decorative panel 40 is fitted into the opening of the mounting portion 12. With the above-mentioned configuration, the surface of the door lining 1 and the decorative panel 40 are formed to be substantially flush with each other.

[0024] The shock absorbing portion 13 is a shock absorbing body provided between the door panel D1 and the door lining 1 in order to reduce the shock applied to a seated occupant from the vehicle door D in the event of a side collision of the vehicle. Specifically, the impact absorbing portion 13 is formed as a substantially circular convex portion, and is formed so as to be narrowed stepwise from the door lining 1 toward the door panel D1. In other words, it is formed so as to protrude in a step-like manner. With the above-mentioned configuration, the door D is deformed appropriately according to the displacement amount (deformation amount) of the vehicle door D, so that the load applied during a collision can be suppressed.

[0025] As shown in Figures 3 and 4, the skin material 20 is made of a resin material (e.g., TPO), fabric (e.g., PET material), genuine leather, etc., and is formed into a shape capable of covering the interior surface of the door lining base material 10. Specifically, the skin material 20 has a first skin material 21 that covers the portion above the armrest base material portion 11 on the interior surface of the door lining base material 10, and a second skin material 22 that covers the portion below the armrest base material portion 11. The end portions of the first skin material 21 and the second skin material 22 are attached to skin attachment portions provided on the door lining base material 10. The door lining 1 does not necessarily have to have the skin material 20.

[0026] As shown in Figures 3 and 4, the light-emitting member 30 is a planar light-emitting body that is long in the front-to-rear direction of the seat, and is specifically composed of a light source 31 such as an LED lamp, a light guide 32 that guides the light emitted from the light source 31, and a light-emitting panel 33 that emits the guided light evenly over the entire surface. The light emitting member 30 may be a surface light emitting device such as an LED display or an organic EL display.

[0027] The light emitting member 30 is disposed in the approximate center of the door lining 1. Specifically, the light emitting member 30 is disposed between the power generating member 50 and the power storing member 60 in the vertical direction. A decorative panel 40 is disposed at a position on the vehicle interior side facing the light emitting member 30.

[0028] As shown in Figs. 2 to 4, the decorative panel 40 is a planar resin member exposed to the inside of the vehicle, has optical transparency, and functions as decorative lighting. Specifically, the decorative panel 40 has a light-emitting area 41 on the panel surface, and when illuminated by the light-emitting members 30, it can display a predetermined decorative pattern. More specifically, a "touch panel" serving as an information display screen is formed in the light-emitting region 41. Then, while the light-emitting member 30 is emitting light, the "touch panel" is lit in the light-emitting region 41 to display information. On the other hand, while the light-emitting member 30 is not emitting light, the "touch panel" is turned off, and the decorative panel 40 is configured to blend in with the surface of the door lining 1.

[0029] Here, at least one of still image information, video information, and text information is displayed on the "touch panel." Displaying various information on the "touch panel" can improve comfort inside the vehicle. In this embodiment, as shown in Fig. 2, the "touch panel" displays information such as the current time, weather, room temperature, and humidity. In addition, operation buttons for operating the reclining mechanism and height link mechanism of the vehicle seat S are also displayed. It should be noted that the present invention is not limited to these pieces of information, and for example, existing operation buttons on windows, car audio, car navigation systems, etc. may be replaced with a "touch panel" and displayed. The above configuration allows the seat occupant to operate the "touch panel" depending on their mood or situation, and to switch the information displayed on the "touch panel," improving comfort inside the vehicle. It also has the effect of reducing the number of parts and securing space inside the vehicle. Furthermore, it also improves the design compared to conventional models.

[0030] As shown in FIGS. 2 to 5, the power generating member 50 is a film-like solar cell module that is attached to the upper portion (upper end portion) of the door lining 1 and is disposed along the surface of the door lining 1 on the vehicle interior side. Specifically, the power generating member 50 is an organic thin-film type solar cell module, and as shown in FIG. 5, is mainly composed of a power generating body having a solar cell 51, a sealing layer 52 that seals the solar cell 51, and a surface layer 53 provided on the surface side of the power generating member 50 relative to the sealing layer 52, and a resin film substrate 54 that serves as the substrate for the power generating body. A plurality of power generating elements including solar cells 51 are arranged over substantially the entire surface of the film substrate 54 (distributed so as to be diffused). The power generating member 50 may be an organic thin film type solar cell module or a perovskite type solar cell module. The above-mentioned film-like solar cell module can be shaped or attached to match the design shape of the door lining 1. This makes it possible to realize a power generating member that is lighter and thinner than conventional ones.

[0031] The solar cell 51 is an energy conversion element that absorbs light energy emitted from the sun and converts it into electricity, and is made of a semiconductor such as silicon. The sealing layer 52 is formed by sealing the solar cell 51 with a resin adhesive. The surface layer 53 is formed by laminating a translucent resin material (for example, ETFE (ethylene tetrafluoroethylene)), which allows the solar cell 51 to generate power efficiently. Furthermore, the surface of the surface layer 53 is formed with fine projections and recesses by, for example, drawing. For example, the surface layer 53 has a fine projection and recess shape with an arithmetic mean roughness Ra of 50 nm or more and 5 μm or less. This improves the design of the surface of the power generation member 50. Furthermore, scratches and dirt on the surface can be made less noticeable.

[0032] The generator member 50 is disposed at the upper end portion of the door lining 1 and is attached while being curved along the surface of the skin material 20 of the door lining 1. Therefore, the film-like power generating member 50 can be suitably attached while conforming to the surface of the door lining 1. Furthermore, by attaching the power generating member 50 to a portion that is likely to be directly exposed to sunlight, power can be generated efficiently.

[0033] In addition, a light-storing material may be laminated at a position different from the solar cell 51 (power generating body) on the film substrate 54 to form a separate light-storing body that absorbs sunlight. In this way, electricity can be suitably discharged from the power generating member 50. Also, a new design feature can be added.

[0034] As shown in FIGS. 3 and 4, the electricity storage member 60 is a plate-shaped storage battery that stores the electricity generated by the power generation member 50 and supplies the electricity to the light emitting member 30. The electricity storage member 60 is disposed below the light emitting member 30 and the power generating member 50, and is attached to the lower end of the armrest base material portion 11 in the door lining base material 10.

[0035] As shown in FIG. 4, the connection member 70 is a film-like electric circuit (current collecting sheet) and is mainly composed of, for example, a conductive film substrate 70a and metal wiring 70b formed by processing the surface of the film substrate 70a. The connection member 70 includes a first connection member 71 that connects the light emitting member 30, the power generating member 50, and the controller 80, and a second connection member 72 that connects the light emitting member 30, the electricity storing member 60, and the controller 80.

[0036] One end of the first connecting member 71 passes through a through hole 14 provided in the door lining base material 10 and is electrically connected to the lower end of the generator member 50 . The other end of the first connection member 71 is connected to the light emitting member 30 and the controller 80 in a state where it is sandwiched between the light emitting member 30 and the controller 80. One end of the second connecting member 72 is connected to and sandwiched between the light emitting member 30 and the controller 80. The other end of the second connection member 72 is connected to the upper end of the electricity storage member 60.

[0037] In the above configuration, since the connection member 70 is made of a film-like electric circuit as shown in Fig. 4, it can be arranged more compactly than a conventional harness. In addition, the door lining 1 can be made lighter.

[0038] In the above configuration, as shown in FIG. 3, the light-emitting member 30 and the storage member 60 are positioned above the reinforcing member D4 and the impact absorbing portion 13 when viewed from the side of the door lining 1, and are positioned to avoid the reinforcing member D4 and the impact absorbing portion 13. Therefore, the light emitting member 30 and the electricity storage member 60 can be easily attached and detached.

[0039] 3 and 4, the light emitting member 30 and the electricity storage member 60 are arranged in a position where they overlap with each other in the vehicle front-rear direction and in the thickness direction of the door lining 1, and are arranged in close proximity to each other. The light emitting member 30 and the electricity storage member 60 are also arranged in a position on the vehicle outer side with respect to the decorative panel 40. Therefore, the light emitting members 30 and the electricity storage members 60 can be arranged compactly, and electricity can be efficiently supplied from the electricity storage members 60 to the light emitting members 30.

[0040] 3 and 4, the decorative panel 40 is disposed closer to the vehicle interior than the light-emitting member 30, the power-generating member 50, and the electricity-storing member 60. Therefore, the decorative panel 40 can improve the design.

[0041] The controller 80 is a control device that comprehensively performs electrical control of the lighting function of the door lining 1, as shown in FIGS. As shown in FIG. 6, the control controller 80 is connected to the light-emitting member 30 (decorative panel 40), the power generation member 50, and the electricity storage member 60, and controls the supply of electricity from the power generation member 50 or the electricity storage member 60 to the light-emitting member 30 and the decorative panel 40 based on a predetermined user operation input by the seated occupant. By doing so, a predetermined decorative pattern can be displayed in the light emitting area 41 of the decorative panel 40. Alternatively, the light emitting area 41 can display a "touch panel" as an information display screen.

[0042] In addition, as shown in FIG. 6, the control controller 80 is electrically connected to a power source P (e.g., an on-board battery) provided in the vehicle body via a connecting member not shown, and performs electrical control of the door lining 1 while receiving and transmitting electrical power between the power source P. Specifically, the control controller 80 controls the supply of electricity from the power source P to the electrical components when the amount of electricity generated by the power generating member 50 is less than a predetermined threshold value, or when the amount of electricity stored in the storage member 60 is less than a predetermined threshold value. In other words, when the amount of electricity generated by the power generating member 50 and the electricity storing member 60 is insufficient, power is supplied from the power source P on the vehicle body side. In addition, the control controller 80 controls the supply of electricity from the power generating member 50 or the storage member 60 to the power source P or electrical components when the amount of electricity generated by the power generating member 50 is equal to or greater than a predetermined threshold, or when the amount of electricity stored in the storage member 60 is equal to or greater than a predetermined threshold. In other words, when the amount of electricity generated by the power generation member 50 and the electricity storage member 60 is sufficient, electricity is supplied to the power source P and electrical components on the vehicle body side.

[0043] With the above configuration, it is possible to realize the door lining 1 that can provide illumination function within the vehicle even if electricity is not supplied from the power source P of the vehicle body. In addition, the components required for the illumination function can be arranged compactly, making it possible to reduce the weight compared to conventional methods. Also, the power generating member 50 can generate electricity efficiently.

[0044] <Second embodiment> Next, a door lining 101 according to a second embodiment will be described with reference to FIG. Incidentally, explanations of contents overlapping with those of the above-mentioned door lining 1 will be omitted. The door lining 101 differs from the door lining 1 mainly in the configuration of components for achieving the lighting function.

[0045] The door lining 101 includes a light emitting member 130 having a light emitting area 132, a power generating member 150, a power storage member 160, a connection member 170, and a controller 180 as a lighting module to provide lighting within the vehicle. The light emitting member 130, the power generating member 150, the electricity storing member 160, and the connecting member 170 are integrally formed in a film shape, and are attached integrally to the surface of the skin material 120 of the door lining 101.

[0046] The light emitting member 130 is a film-like light emitting body, and is formed by printing an inorganic compound (e.g., zinc sulfide) on a conductive film substrate 131 (e.g., a PET film substrate). The surface of the light emitting member 130 is formed as a light emitting region 132. The power generating member 150 is a film-like solar cell module, and is formed by laminating a laminate including solar cells on the film substrate 131 described above. The electricity storage member 160 is a film-type storage battery (for example, a film-type lithium ion secondary battery), and is formed by applying a gel-like or jelly-like electrolyte material onto the film substrate 131. The connection member 170 is a film-like electric circuit, and the electric circuit is formed by providing metal wiring on the film substrate 131.

[0047] The connection member 170 includes a first connection member 171 that connects the light emitting member 130 , the power generating member 150 and the controller 180 , and a second connection member 172 that connects the light emitting member 130 and the electricity storing member 160 . The controller 180 is a microcontroller, and is disposed between the light emitting member 130 and the power generating member 150 and is attached to the rear surface of the film substrate 131 .

[0048] With the above configuration, it is possible to realize a door lining that can provide lighting function within the vehicle even if electricity is not supplied from the vehicle body's power source. In addition, the components required for providing the lighting function can be arranged more compactly, making the module lighter than ever before. Also, the module can be easily attached to the door lining of a vehicle.

[0049] Third to Eighth Embodiments Next, the door linings 201, 301, 401, 501, 601, and 701 of the third to eighth embodiments will be described with reference to Figs. 8A to 8F. The door linings of the third to eighth embodiments are different from the door lining 1 in the arrangement of the light emitting member and the electricity storing member. It should be noted that illustrations and descriptions of the decorative panel, the connection members, and the controller are omitted.

[0050] As shown in FIG. 8A, the door lining 201 of the third embodiment includes a light emitting member 230, a power generating member 250, and a power storing member 260 as an illumination module. The light emitting member 230 and the electricity storage member 260 are arranged side by side in the front-rear direction of the vehicle (on the same horizontal plane) in order to be compactly arranged. The light emitting member 230 and the electricity storing member 260 are disposed below the reinforcing member D4 in a side view of the door lining 201, and are disposed at positions that avoid the reinforcing member D4. Moreover, the light emitting member 230 and the electricity storing member 260 are disposed in a position forward of the shock absorbing portion 213 and are disposed at a position avoiding the shock absorbing portion 213. Therefore, the light emitting member 230 and the electricity storing member 260 can be easily attached and detached.

[0051] As shown in FIG. 8B, the door lining 301 of the fourth embodiment includes a light emitting member 330, a power generating member 350, and a power storing member 360 as an illumination module. The light emitting member 330 and the electricity storage member 360 are arranged side by side in the front-rear direction of the vehicle (on the same horizontal plane) in order to be compactly arranged. The light emitting member 330 and the electricity storing member 360 are disposed at positions overlapping with the arm rest 302 when the door lining 301 is viewed from the side. Moreover, the light emitting member 330 and the electricity storing member 360 are disposed at a position above the reinforcing member D4 and at a position avoiding the reinforcing member D4. Furthermore, the light emitting member 330 and the electricity storage member 360 are disposed in a position forward of the shock absorbing portion 313 and are disposed at a position avoiding the shock absorbing portion 313. Therefore, the light emitting member 330 and the electricity storing member 360 can be easily attached and detached.

[0052] As shown in FIG. 8C, a door lining 401 of the fifth embodiment includes a light emitting member 430, a power generating member 450, and a power storing member 460 as an illumination module. The light emitting member 430 and the electricity storing member 460 are disposed at positions where they at least partially overlap the reinforcing member D4 when the door lining 401 is viewed from the side. Therefore, the light emitting member 430 and the electricity storage member 460 are protected by the reinforcing member D4. The light emitting member 430 and the electricity storage member 460 may be disposed in a position where they entirely overlap with the reinforcing member D4. Moreover, the light emitting member 430 and the electricity storing member 460 are disposed in a position forward of the shock absorbing portion 413 and in a position avoiding the shock absorbing portion 413. Therefore, the light emitting member 430 and the electricity storing member 460 can be easily attached and detached.

[0053] As shown in FIG. 8D, the door lining 501 of the sixth embodiment includes a light emitting member 530, a power generating member 550, and a power storing member 560 as an illumination module. The light emitting member 530 is disposed at a position above the reinforcing member D4 and the impact absorbing portion 513 in a side view of the door lining 501, and is disposed at a position that avoids the reinforcing member D4 and the impact absorbing portion 513. Therefore, the light emitting member 530 can be easily attached and detached. Moreover, the electricity storage member 560 is disposed at a position overlapping the reinforcing member D4 and at a position overlapping the impact absorbing portion 513. Therefore, the electricity storage member 560 is protected by the reinforcing member D4. The electricity storage member 560 may be disposed at a position where it partially overlaps with the reinforcing member D4 and the shock absorbing parts 513.

[0054] As shown in FIG. 8E, a door lining 601 according to the seventh embodiment includes a light emitting member 630, a power generating member 650, and a power storing member 660 as an illumination module. The light emitting member 630 is disposed at a position overlapping the reinforcing member D4 in a side view of the door lining 601, and is also disposed at a position overlapping the impact absorbing portion 613. Therefore, the light emitting member 630 is protected by the reinforcing member D4 and the shock absorbing portion 613. The light emitting member 630 may be disposed at a position where it partially overlaps with the reinforcing member D4 and the shock absorbing portion 613. Moreover, the electricity storage member 660 is disposed below the reinforcing member D4 and in front of the shock absorbing parts 613. This makes it easier to attach and detach the light emitting member 630.

[0055] As shown in FIG. 8F, a door lining 701 according to the eighth embodiment includes a light emitting member 730, a power generating member 750, and a power storing member 760 as an illumination module. The light emitting member 730 and the electricity storing member 760 are disposed above the reinforcing member D4 and the impact absorbing portion 713 when the door lining 701 is viewed from the side. The light emitting member 730 is disposed between the power generating member 750 and the electricity storing member 760 in the vehicle front-rear direction. The light emitting member 730 is provided at a position adjacent to the operating handle 703 and is disposed at a position overlapping with the storage recess in which the operating handle 703 is stored. Therefore, the empty space around the operating handle 703 can be suitably illuminated.

[0056] With the above configuration, it is possible to realize a door lining that can provide lighting function within the vehicle even if electricity is not supplied from the vehicle body's power source. Furthermore, the components required for providing the lighting function can be arranged more compactly, and the module can be easily attached to a vehicle door lining.

[0057] Furthermore, with the above-mentioned arrangement of light-emitting member 730, power generation member 750, and electricity storage member 760, even if an impact load is applied to vehicle door D during a side collision of the vehicle, the impact on light-emitting member 730, power generation member 750, and electricity storage member 760 can be mitigated. More specifically, when an impact load is applied to the vehicle door D during a side collision of the vehicle, the area where the reinforcing member D4 and the impact absorbing portion 713 are provided will be most affected. At this time, the light emitting member 730, the power generating member 750, and the electricity storing member 760 are disposed at positions that avoid the reinforcing member D4 and the impact absorbing portion 713, so that the effect of the impact load can be suppressed.

[0058] Furthermore, with the above-described arrangement of the light emitting member 730 and the electricity storing member 760, they are disposed close to the front end of the vehicle door D, and are also disposed close to the power source (power source system) provided in the vehicle body. This allows the lighting module to efficiently receive power from the vehicle's power supply, minimizing electrical loss.

[0059] <Other embodiments> In the above embodiment, as shown in FIG. 3, the vehicle door lining 1 includes a light-emitting member 30, a power-generating member 50, and a power-storing member 60 to provide a lighting function within the vehicle interior. However, the present invention is not particularly limited to this, and may be applied to vehicle interior accessories other than the vehicle door lining. For example, a vehicle interior component such as an instrument panel, a console box, a rear tray, or the like may include the light emitting member 30, the power generating member 50, and the electricity storing member 60.

[0060] In the above embodiment, as shown in Figs. 3 and 4, the power generating member 50 and the connecting member 70 are formed from sheet-like or film-like members, but this is not particularly limited and can be modified. For example, the power generating member 50 may be a plate-shaped or panel-shaped solar cell, and the connection member 70 may be a conventional electrical wiring or a harness that bundles together a plurality of electrical wirings. Preferably, the power generating member 50 and the connection member 70 are made of a flexible material in a sheet or film shape. More preferably, the light emitting member 30 and the electricity storage member 60 are also made of a flexible material in a sheet or film shape. Even more preferably, the light emitting member 30 has a light emitting region and serves the function of the decorative panel 40, thereby making the decorative panel 40 unnecessary.

[0061] <First embodiment of vehicle seat> Next, the vehicle seat S1 of the first embodiment will be described with reference to Figs. 9 to 12A and 12B. The vehicle seat S1 is a seat that can efficiently receive the load applied to the seat back from an occupant during a rear-end collision of the vehicle. More specifically, the vehicle seat S1 has a seat back constructed by bonding a cover material to a padding material, and realizes a seat that can efficiently absorb the load applied to the seat back by the occupant during a rear-end collision of the vehicle.

[0062] As shown in Figures 9 and 10, the vehicle seat S1 comprises a seat body having a seat cushion 1001 and a seat back 1002, a lumbar support 1030 attached to the inside of the seat back 1002 and movable to protrude a central portion 1002A of the seat back 1002 toward the occupant from its normal position, a movable body 1040 (side support member) attached to the inside of the seat body and movable to protrude a side portion 1002B of the seat back 1002 toward the occupant from its normal position, and an operating device 1050 (fluid supply device) that operates to move the lumbar support 1030 and the movable body 1040.

[0063] As shown in FIG. 9, the seat cushion 1001 is a seating portion that supports a seated person from below, and is configured by placing a pad material 1001a on a cushion frame 1010 shown in FIG. 10, which serves as the skeleton, and covering it with a cover material 1001b. As shown in FIG. 9, the seat back 1002 is a backrest portion that supports the back of a seated occupant from behind, and is configured by placing a pad material 1002a on a back frame 1020 shown in FIG. 10, which serves as the skeleton, and covering it with a skin material 1002b. The seat back 1002 is composed of a central portion 1002A located in the center in the seat width direction, and left and right side portions 1002B (side bolster portions) located on the outer sides of the central portion 1002A in the seat width direction. On the surface of the pad material 1002a, left and right hanging grooves 1002C are formed which extend in the vertical direction so as to separate a central portion 1002A from left and right side portions 1002B.

[0064] As shown in Figure 10, the cushion frame 1010 is a rectangular frame-like body and is mainly composed of side frames 1011 arranged on the left and right sides, a plate-shaped pan frame 1012 (mounting frame) mounted on the front end portion of each side frame 1011, a rear connecting frame 1013 connecting the rear portions of each side frame 1011, and a number of support members 1014 (elastic springs) hooked onto the pan frame 1012 and the rear connecting frame 1013 and extending in the fore-and-aft direction of the seat.

[0065] The side frame 1011 is a plate-shaped frame that is long in the front-rear direction of the seat. A reclining device 1004 is attached to the rear portion of the side frame 1011, and a rail device 1006 is attached below the reclining device 1004 via a height link device 1005.

[0066] As shown in FIG. 10, the back frame 1020 is a rectangular frame-like body and is mainly composed of back side frames 1021 arranged on the left and right sides, an inverted U-shaped upper frame 1022 connecting the upper end portions of each back side frame 1021, a plate-shaped lower frame 1023 connecting the lower end portions of each back side frame 1021, a number of wire members 1024 (elastic wires) that are hooked onto each back side frame 1021 and extend in a snake-like shape in the width direction of the seat, and a support plate 1025 that is held by the multiple wire members 1024 and supports the seated occupant.

[0067] The back side frame 1021 is a sheet metal member that extends in the vertical direction and has a generally C-shaped cross section. In the above configuration, the back frame 1020 is capable of rotating relative to the cushion frame 1010.

[0068] In the above configuration, a lumbar support 1030 is attached to the front surface of the lower portion of the support plate 1025, as shown in FIG. As shown in FIG. 10, left and right movable bodies 1040 are attached to the front surfaces of the lower portions of the left and right back side frames 1021.

[0069] As shown in Figures 10 to 12A and B, the lumbar support 1030 has a bag (air cell) that expands when a fluid is sealed inside, and expands toward the occupant (protruding from the normal position to the protruding position) when compressed air is sealed inside as the fluid, and contracts (returns to the normal position) when the sealed compressed air is released. Specifically, the lumbar support 1030 is a member that supports the lumbar region of the seated occupant, and is disposed between the pad material 1002a and the support plate 1025 in the central portion 1002A of the lower portion of the seat back 1002. The lumbar support 1030 is a movable member that allows the central portion 1002A (pad material 1002a) to protrude toward the seated occupant. The lumbar support 1030 is attached to the front of the support plate 1025 in a folded state.

[0070] The lumbar support 1030 has a rectangular shape that is elongated in the seat width direction, and is mainly composed of a base member 1031 (base plate) supported by the support plate 1025, and a bag body 1032 supported on the front surface of the base member 1031. The bag body 1032 can expand toward the front side of the seat when compressed air is enclosed in the folded state.

[0071] As shown in Figures 10 to 12A and B, the movable body 1040 has a bag body (air cell) that expands towards the seated occupant (protruding from the normal position to the protruding position) when compressed air is enclosed inside, and contracts (returns to the normal position) when the enclosed compressed air is discharged. Specifically, the movable body 1040 is a side support member that supports the seated occupant from the side, and is disposed between the pad material 1002a and the back side frame 1021 in the side portion 1002B in the lower portion of the seat back 1002. The movable body 1040 is a movable member that causes the side portion 1002B (pad material 1002a) to protrude toward the seated occupant (toward the front of the seat and inward in the seat width direction). The movable body 1040 is attached to the front surface of the back side frame 1021 in the folded state.

[0072] The movable body 1040 has an approximately pentagonal shape that is elongated in the vertical direction, and is mainly composed of a base member 1041 supported by the back side frame 1021, a rotating member 1043 that is positioned further forward in the seat than the base member 1041 and is attached so as to be rotatable relative to the base member 1041 via a rotating shaft 1042, and a bag body 1044 that is positioned between the base member 1041 and the rotating member 1043 and supported on the front surface of the base member 1041.

[0073] The base member 1041 is attached to the front surface of the back side frame 1021 and extends so as to protrude in the seat width direction along the front surface of the back side frame. The rotating shaft 1042 is attached to the inner end portion in the seat width direction of the front surface of the base member 1041 . The rotating member 1043 is attached to the base member 1041 so as to be rotatable in the front-rear direction of the seat, and can cause the side portion 1002B of the seat back 1002 to protrude (push out) toward the front of the seat by rotating toward the front of the seat. When the seat back 1002 is in the normal position, the rotating member 1043 is disposed at a position shifted toward the base member 1041. The rotating member 1043 may be biased toward the base member 1041 by a biasing spring (biasing member) (not shown).

[0074] The bag body 1044 is supported by the base member 1041, and when compressed air is enclosed inside, the bag body 1044 expands toward the front side of the seat, and can push the rotating member 1043 toward the front of the seat. In other words, the rotating member 1043 can be rotated toward the front of the seat. With the above-described configuration, by inflating the bag body 1044, the protruding direction and protruding amount of the seat back 1002 (side portion 1002B) can be adjusted.

[0075] As shown in Figures 10 and 11, the actuator 1050 is attached inside the seat body, and is a fluid supply device for supplying compressed air to the lumbar support 1030 (bag body 1032) and the movable body 1040 (bag body 1044). The operating device 1050 is mainly composed of an air control unit 1051 attached to the outer surface of the backside frame 1021, an air pump 1052 attached to the back surface of the cushion frame 1010 (pan frame 1012) for supplying (air supply) and discharging (exhaust) compressed air, and air piping 1053 connecting the air pump 1052 and the lumbar support 1030 (movable body 1040).

[0076] The air control unit 1051 receives a predetermined control signal, for example, by accepting a selection of a predetermined user operation by the seat occupant, and controls the air pump 1052 to supply compressed air to the bags 1032, 1044 and to exhaust compressed air from the bags 1032, 1044. This allows the range of motion of the lumbar support 1030 and the movable body 1040 to be adjusted according to the physique of the seated occupant.

[0077] In the above configuration, as shown in FIG. 12A, when the lumbar support 1030 causes the central portion 1002A of the seat back 1002 to protrude most toward the front of the seat, the rear end portion of the movable body 1040 is positioned toward the front of the seat relative to the seating surface of the central portion 1002A of the seat back 1002. In other words, the plurality of bags 1044 are disposed on the seat front side of the seating surface of the central portion 1002A of the seat back 1002. Therefore, the occurrence of wrinkles or sagging in the covering material 1002b of the seat back 1002 can be suppressed.

[0078] Next, the operation of the movable body 1040 will be described in detail with reference to FIGS. 12A and 12B. The movable body 1040 is movable to move the side portion 1002B of the seat back 1002 from the "normal position" shown in FIG. 12A to the "protruding position" shown in FIG. 12B.

[0079] FIG. 12A is a diagram showing a state in which the side portion 1002B of the seat back 1002 is in the "normal position." FIG. 12B is a diagram showing a state in which the movable body 1040 protrudes forward of the seat and the side portion 1002B moves from the "normal position" to the "protruding position." Specifically, by receiving a supply of compressed air from the operating device 1050, the folded bag body 1044 inflates and unfolds toward the front of the seat, and the side portion 1002B moves toward the front of the seat by pushing the rotating member 1043 toward the front of the seat. As a result, the side portion 1002B moves to the "protruding position." When the operating device 1050 discharges the compressed air from inside the bag 1044, the inflated bag 1044 contracts, and the side portion 1002B moves downward toward the rear of the seat. As a result, the side portion 1002B returns from the "protruding position" to the "normal position."

[0080] In addition to the above configuration, the padding material 1002a and the covering material 1002b are adhered to each other by an adhesive portion 1060, as shown in FIG. 12A. The adhesive portion 1060 is a portion where adhesive is provided, and is applied to the surface of the pad material 1002a continuously or at predetermined intervals in the vertical direction and the sheet width direction. The adhesive portion 1060 has a central adhesive portion 1061 arranged in a central portion 1002A of the seat back 1002, and a first side adhesive portion 1062 and a second side adhesive portion 1063 arranged in the side portion 1002B.

[0081] The central adhesive portion 1061 is disposed at a position overlapping with the lumbar support 1030 in the seat width direction and the up-down direction. Further, the central adhesive portion 1061 is disposed on the inner side of the left and right hanging grooves 1002C in the sheet width direction. In detail, the central adhesive portion 1061 is positioned inward in the sheet width direction from the left and right surface fragile portions 1070 formed on the surface of the padding material 1002a, and is also positioned inward from the left and right back surface fragile portions 1080 formed on the back surface of the padding material 1002a.

[0082] The first side adhesive portion 1062 is disposed at a position overlapping with the movable body 1040 in the sheet width direction and the up-down direction. The first side adhesive portions 1062 are arranged at predetermined intervals in the sheet width direction and the up-down direction. It should be noted that the first side adhesive portion 1062 is disposed so as to avoid a portion of the side portion 1002B that is likely to be deformed when the movable body 1040 moves (specifically, the portion that is most likely to be deformed). For example, the part of the side portion 1002B that is most susceptible to deformation corresponds to the front end portion of the side portion 1002B. By partially forming the "non-adhesive region" in this manner, it becomes possible for the side portion 1002B to move smoothly when the movable body 1040 moves (see FIG. 12B).

[0083] The second side adhesive portion 1063 is disposed at a position overlapping with the movable body 1040 in the seat front-rear direction and the up-down direction. The second side adhesive portion 1063 is disposed continuously in the seat front-rear direction and the up-down direction. By forming the "adhesive region" in this manner, the padding material 1002a and the covering material 1002b can be appropriately adhered to each other in the side portion 1002B.

[0084] The surface fragile portion 1070 is a groove formed on the surface of the pad material 1002a at a position inside the hanging groove 1002C and adjacent to the hanging groove 1002C. The back surface weakened portion 1080 is a groove formed on the back surface of the pad material 1002a at a position inside the hanging groove 1002C and adjacent to the hanging groove 1002C. The back surface weak portion 1080 is disposed between the front surface weak portion 1070 and the hanging groove 1002C in the sheet width direction. The surface fragile portion 1070 and the back surface fragile portion 1080 are grooves (recesses) formed continuously along the vertical direction, but are not particularly limited thereto and may be grooves (through grooves) formed at a predetermined interval along the vertical direction.

[0085] As described above, the adhesive portion 1060 is provided in the seat back 1002, so that the padding material 1002a and the covering material 1002b can be appropriately adhered to each other. In addition, by forming a "non-adhesive area" in the seat back 1002 and forming a surface weak portion 1070 and a back surface weak portion 1080, a vehicle seat can be realized that can efficiently withstand the load applied to the seat back 1002 by an occupant during a rear-end collision of the vehicle. Specifically, the load applied to the seat back 1002 by the occupant during a rear-end collision can be efficiently received by the support plate 1025.

[0086] <Second embodiment> Next, a vehicle seat S2 according to a second embodiment will be described with reference to Figs. 13 to 14A and 14B. It should be noted that the description overlapping with the above-mentioned vehicle seat S1 will be omitted. The vehicle seat S2 is provided with a blower device inside the seat body, and realizes a seat that can appropriately secure a space for arranging a duct of the blower device. Further, the vehicle seat S2 realizes a seat that can prevent unintended contact between the upholstery material and the duct in the seat body.

[0087] The vehicle seat S2 includes a seat cushion 1101, a seat back 1102, and a blower device 1130 attached to the inside of the seat cushion 1101, as shown in FIG. 13 and FIG. 14A. In the seat cushion 1101, the padding material 1101a and the cover material 1101b are bonded together by an adhesive portion 1160.

[0088] The blower device 1130 is attached to the bottom surface of the seat cushion 1101 (the pad material 1101a). The blower device 1130 is configured to blow air from a blower body 1131 through a duct 1132, an air passage 1133 formed in the pad material 1101a, and an air hole 1134 toward an occupant (a person seated in the seat).

[0089] The duct 1132 is disposed at the rear end portion on the left side of the seat cushion 1101 (the padding 1101a), and extends in the vertical direction. More specifically, the duct 1132 is disposed at a position avoiding the padding material 1101a, and extends in the vertical direction so as to face the outer edge portion of the padding material 1101a. In other words, in the pad material 1101a, a cutout portion 1170 (duct escape portion) for preventing interference with the duct 1132 is formed in the portion corresponding to the duct 1132.

[0090] The adhesive portion 1160 is a portion where adhesive is provided, and is applied to the surface of the pad material 1101a continuously or at intervals along the sheet front-rear direction and the sheet width direction. The adhesive portion 1160 has an upper surface adhesive portion 1161 applied to the upper surface of the pad material 1101a, and a side surface adhesive portion 1162 applied to the outer surface of the pad material 1101a.

[0091] In the above configuration, as shown in FIG. 14A, side surface adhesive portion 1162 is formed in the portion adjacent (close to) duct 1132 among the outer edge portion of pad material 1101a. This allows the padding 1101a and the covering material 1101b to be appropriately attached to each other around the duct 1132, and prevents the covering material 1101b and the duct 1132 from coming into unintentional contact with each other. In other words, the skin 1101b does not unintentionally shake and move around the periphery of the duct 1132 (for example, above the duct 1132), and it is possible to suppress the generation of abnormal noise caused by contact between the skin 1101b and the duct 1132. The passage area of ​​the duct 1132 can be secured and increased.

[0092] As a first modification of the seat cushion 1101, a curved cutout portion 1170 (duct escape portion) may be formed in the outer edge portion of the pad material 1101a as shown in Fig. 14B. In addition, it is preferable that a side adhesive portion 1162 is provided in the cutout portion 1170. By doing so, unintentional contact between the skin 1101b and the duct 1132 can be further prevented.

[0093] <Third embodiment> Next, a vehicle seat S3 according to a third embodiment will be described with reference to Figs. 15 to 17D. Incidentally, description of the contents overlapping with those of the above-mentioned vehicle seats S1 to S2 will be omitted. The vehicle seat S3 is provided with a blower device inside the seat body, and realizes a seat that can ensure air conditioning capacity by the blower device without depending on a means for attaching the upholstery material. Furthermore, the vehicle seat S3 is provided with a detection sensor (seat occupancy sensor) inside the seat body, and realizes a seat that can improve the detection accuracy of the detection sensor without relying on an attachment means for the cover material.

[0094] As shown in FIGS. 15 and 16, the vehicle seat S3 includes a seat cushion 1201, a seat back 1202, a blower device 1230 attached inside the seat cushion 1201, and a detection sensor 1240 attached inside the seat cushion 1201. In the seat cushion 1201, the pad material 1201a and the cover material 1201b are bonded together by an adhesive portion 1260.

[0095] The detection sensor 1240 is a planar pressure sensor that detects the seating pressure of a seated person, and is also called a seating sensor. As shown in FIG. 16, the detection sensor 1240 is attached to the center of the cushion frame 1210 in the seat front-rear direction and the seat width direction. As shown in FIG. 17A, the detection sensor 1240 has a detection unit 1241 that detects the seating pressure of a seated person, and a transmission path 1242 for transmitting the detection data obtained by the detection unit 1241 to a control device (not shown). The detection portion 1241 abuts against the bottom surface of the pad material 1201a.

[0096] More specifically, the detection sensor 1240 (detection portion 1241 ) is attached onto the cushion frame 1210 via a mounting bracket 1243 . The detection sensor 1240 is accommodated in a sensor accommodating recess 1244 formed in the bottom surface of the pad material 1201a.

[0097] In the above configuration, as shown in FIG. 17A, the detection sensor 1240 is disposed at a position different from the adhesive portion 1260 that adheres the pad material 1201a and the cover material 1201b in the seat front-rear direction and the seat width direction. In other words, the detection sensor 1240 is disposed at a position that does not face the "bonded area" where the bonded portion 1260 is formed. By doing so, it is possible to ensure the detection accuracy of the detection sensor 1240 regardless of the means for attaching the cover material 1201b (without being affected by adhesion).

[0098] The blower device 1230 is attached to the bottom surface of the cushion frame 1210 as shown in FIGS. The blower device 1230 is configured to blow air towards the occupants through a duct 1232, an air passage 1233, and a number of air vents 1234. As shown in FIG. 17B, the duct 1232 is attached to the cushion frame 1210 via a mounting bracket 1235, and extends in the vertical direction. As shown in FIGS. 17A and 17B, the ventilation passage 1233 is connected to the duct 1232, and is branched into a plurality of passages so as to extend in the front-rear direction of the seat and in the width direction of the seat. The plurality of ventilation holes 1234 are connected to the ventilation passage 1233 and extend in the vertical direction.

[0099] In the above configuration, as shown in Fig. 17A, the ventilation path 1233 is disposed at a position not facing the "bonding region" where the bonding portion 1260 is formed. Also, as shown in Fig. 17B, the ventilation path 1233 is disposed at a position not facing the "bonding region". Alternatively, as shown in FIG. 17B, the duct 1232 and the ventilation passage 1233 are disposed at positions facing a "partially bonded region" where the bonded parts 1260 are formed with an interval therebetween. In other words, the duct 1232, the ventilation passage 1233, and the ventilation hole 1234 are arranged at positions that avoid the "completely bonded region" where the adhesive portion 1260 is continuously formed. By doing so, it becomes easier to ensure the air conditioning capacity of the blower device 1230 regardless of the mounting means of the covering material 1201b (not affected by adhesion). In addition, the "partially bonded regions" formed by the bonded parts 1260 with a space therebetween are high hardness regions where the pad material 1201a has a relatively high hardness. Therefore, it is possible to suppress the influence of the seating load of the occupant on the air conditioning passage.

[0100] As a second modified example of the seat cushion 1201, as shown in FIGS. 17C and 17D, a detection sensor 1240, a duct 1232, an air passage 1233, and an air hole 1234 may be provided. The detection sensor 1240 is disposed at a position facing the "bonded area" where the bonded portion 1260 is formed. The peripheral position of the detection sensor 1240 is disposed so as to face a "non-bonded region" where the bonded portion 1260 is not formed. The peripheral position of the detection sensor 1240 may be disposed so as to face a "partially bonded region". By doing so, it is possible to ensure the detection accuracy of the detection sensor 1240.

[0101] Also, as shown in Figures 17C and 17D, the ventilation path 1233 is positioned opposite a "completely bonded region" where the adhesive portions 1260 are formed continuously, or a "partially bonded region" where the adhesive portions 1260 are formed with gaps between them. Furthermore, as shown in FIG. 17D, the duct 1232 is disposed at a position opposite to the "partially bonded region". The "completely bonded region" and the "partially bonded region" are high hardness regions where the pad material 1201a has a relatively high hardness. This makes it possible to suppress the effect of the seating weight of the occupants and the like on the air conditioning passage, and thus to suppress a decrease in air conditioning capacity.

[0102] <Fourth embodiment> Next, a vehicle seat S4 according to a fourth embodiment will be described with reference to FIGS. Incidentally, description of the contents overlapping with those of the above-mentioned vehicle seats S1 to S3 will be omitted. The vehicle seat S4 is provided with a blower device inside the seat body, and realizes a seat that can ensure air conditioning capacity by the blower device without depending on a means for attaching the cover material.

[0103] The vehicle seat S4 includes a seat cushion 1301, a seat back 1302, and a blower device 1330 attached inside the seat cushion 1301. In the seat cushion 1301 , the padding material 1301 a and the cover material 1301 b are bonded together by an adhesive portion 1360 .

[0104] The blower device 1330 is attached to the bottom surface of the cushion frame 1310 as shown in FIGS. The blower device 1330 is configured to blow air towards the occupants through a duct 1332, an air passage 1333, and a number of air vents 1334. The multiple air vents 1334 are arranged in a row in the front-rear direction of the seat, and are spaced apart in the width direction of the seat. The front portion of the seat cushion 1301 where the plurality of ventilation holes 1334 are formed is the "ventilation area." The rear portion of the seat cushion 1301 where the ventilation holes 1334 are not formed is the "non-ventilation area."

[0105] In the above configuration, as shown in Figures 19 and 20, a "ventilation area" in which multiple ventilation holes 1334 are formed in the seat cushion 1301 is configured to correspond to a "non-bonded area" in which the adhesive portion 1360 is not provided. Moreover, the "non-ventilation area" where the ventilation holes 1334 are not formed in the seat cushion 1301 is configured to correspond to the "bonded area" where the bonded portion 1360 is provided. Furthermore, the area of ​​the "ventilation region (non-bonded region)" is larger than the area of ​​the "non-ventilation region (bonded region)". By doing so, the air conditioning capacity of the blower device 1330 can be ensured regardless of the means for attaching the covering material 1301b (not affected by adhesion). Moreover, the cover material 1301b can be suitably adhered and fixed to the pad material 1301a.

[0106] In the above configuration, as shown in FIG. 19, the multiple air holes 1334 are arranged in a row in the front-rear direction of the seat and spaced apart in the width direction of the seat. Similarly, the "bonded area" of the bonded portion 1360 also extends along the front-rear direction and the width direction of the sheet. In this way, the space can be effectively utilized to ensure air conditioning by the blower device 1330 and adhesion by the adhesive portion 1360.

[0107] As shown in FIG. 19, the "ventilation area" in which multiple ventilation holes 1334 are formed in the seat cushion 1301 corresponds to the "non-adhesive area," but it may also correspond to a "partially adhesive area" in which adhesive portions 1360 are formed at intervals. By doing so, the air conditioning capacity of the blower device 1330 can be ensured.

[0108] <Fifth embodiment> Next, a vehicle seat S5 according to a fifth embodiment will be described with reference to FIGS. Incidentally, description of the contents overlapping with those of the above-mentioned vehicle seats S1 to S4 will be omitted. The vehicle seat S5 includes a detection sensor (seat sensor) inside the seat body, and realizes a seat that can ensure detection accuracy by the detection sensor without depending on a means for attaching the cover material.

[0109] The vehicle seat S5 includes a seat cushion 1401, a seat back 1402, and a detection sensor 1440 attached to the inside of the seat cushion 1401. In the seat cushion 1401, the pad material 1401a and the cover material 1401b are bonded together by an adhesive portion 1460.

[0110] The detection sensor 1440 is a planar pressure sensor that detects the seating pressure of a seated occupant. The detection sensor 1440 is mounted on a mounting bracket 1443 fixed on the vehicle floor. The detection sensor 1440 is disposed so as to come into contact with the bottom surface of the pad material 1201a through the opening of the cushion frame 1410. More specifically, the detection sensor 1440 is housed in a sensor housing recess 1444 formed in the bottom surface of the pad material 1401a.

[0111] As described above, by disposing the detection sensor 1440 on the bottom surface of the pad material 1401a, the detection sensor 1440 can be disposed without depending on the attachment means of the cover material 1401b (without being affected by adhesion). In addition, the "bonding region" where the bonding portion 1460 is formed is a high hardness region where the pad material 1401a has a relatively high hardness. Therefore, the seating load of the occupant can be suitably transmitted to the detection sensor 1440, and the detection accuracy of the detection sensor 1440 can be ensured.

[0112] As shown in FIG. 22, the mounting bracket 1443 is fixed onto the vehicle floor, but this is not limited thereto, and it may be fixed to the cushion frame 1410 or the pad material 1401a. When the mounting bracket 1443 is fixed to the padding 1401a, the mounting bracket 1443 may be fixed to the padding 1401a by adhesive, or the mounting bracket 1443 may be integrated with the padding 1401a by integral foam molding.

[0113] Sixth Embodiment Next, a vehicle seat S6 according to a sixth embodiment will be described with reference to FIGS. Incidentally, description of the contents overlapping with those of the above-mentioned vehicle seats S1 to S5 will be omitted. The vehicle seat S6 is equipped with a seat heater inside the seat body, and is designed so as not to affect the installation (adhesion) state of the seat heater even when the padding material and the covering material are fixed with adhesive.

[0114] The vehicle seat S6 includes a seat cushion 1501, a seat back 1502, and a seat heater 1550 attached inside the seat cushion 1501. In the seat cushion 1501, the padding material 1501a and the cover material 1501b are bonded together by an adhesive portion 1560.

[0115] As shown in FIGS. 24 and 25, the seat heater 1550 is a sheet heating element that warms the seat cushion 1501, and is attached by an adhesive portion 1570 to the surface of the pad material 1501a. The "first adhesive region" where the padding material 1501a and the cover material 1501b are adhered by the adhesive portion 1560 is an area that is wider in the seat width direction than in the seat front-rear direction, as shown in Figs. Further, the "second adhesive region" where the padding 1501a and the seat heater 1550 are adhered by the adhesive portion 1570 is an area that is wider in the front-rear direction of the seat than in the width direction of the seat. The “first adhesive region” and the “second adhesive region” are arranged so as to partially overlap each other in the center of the seat cushion 1501. The "first adhesive region" and the "second adhesive region" may be arranged so as not to overlap each other. In other words, the "first adhesive region" of the adhesive portion 1560 may be formed so as to avoid the "second adhesive region" of the adhesive portion 1570.

[0116] In the above configuration, the adhesives used in adhesive portion 1560 and adhesive portion 1570 have different melting points. By doing so, when the seat heater 1550 is adhered to the pad material 1501a by the adhesive portion 1570 and then the cover material 1501b is adhered by the adhesive portion 1560, the adhesion state of the adhesive portion 1570 is not affected. In other words, when the padding material 1501a and the covering material 1501b are bonded together by the adhesive portion 1560, the adhesive portion 1560 is heated and melted at a temperature higher than the melting point of the adhesive portion 1560 and lower than the melting point of the adhesive portion 1570, thereby preventing the adhesive portion 1570 from being affected.

[0117] With the above configuration, a vehicle seat can be realized that is designed not to affect the attachment state (bonding state) of the seat heater 1550, even when the pad material 1501a and the cover material 1501b are fixed with an adhesive.

[0118] Seventh embodiment Next, a vehicle seat S7 according to a seventh embodiment will be described with reference to FIGS. Incidentally, description of the contents overlapping with those of the above-mentioned vehicle seats S1 to S6 will be omitted. The vehicle seat S7 is provided with a seat heater inside the seat body, and realizes a seat that allows the seat heater and the covering material to be efficiently attached to the padding material.

[0119] The vehicle seat S7 includes a seat cushion 1601, a seat back 1602, and a seat heater 1650 attached inside the seat cushion 1601. In the seat cushion 1601, the pad material 1601a and the cover material 1601b are bonded together by an adhesive portion 1660.

[0120] The seat heater 1650 is a sheet heating element that warms the seat cushion 1601, and is attached to the surface of the pad material 1601a. The adhesive portion 1660 is a portion where an adhesive is provided, and is applied to the surface of the pad material 1601a. The "bonding region" where the bonding portion 1660 is provided is formed to be larger than the seat heater 1650, and is wider than the seat heater 1650 in the seat front-rear direction and the seat width direction. The "adhesive region" is disposed between the pad material 1601a and the seat heater 1650 in the vertical direction, and is also disposed between the pad material 1601a and the cover material 1601b in the vertical direction.

[0121] In the above configuration, the adhesive portion 1660 can adhere both the seat heater 1650 and the cover material 1601b to the pad material 1601a. That is, of the "bonding region" where the bonding portion 1660 is provided, the portion that overlaps with the seat heater 1650 becomes the portion where the seat heater 1650 is bonded to the pad material 1601a. Of the "bonding region", the portion that does not overlap with the seat heater 1650 is the portion where the cover material 1601b is bonded to the pad material 1601a.

[0122] With the above-mentioned configuration, it is possible to realize a vehicle seat that allows the seat heater 1650 and the cover material 1601b to be efficiently attached to the pad material 1601a. Specifically, the seat heater 1650 and the cover material 1601b can be bonded to the pad material 1601a at the same time in a single work process (bonding work process).

[0123] The seat heater 1650 may be attached to the rear surface of the cover material 1601b by sewing. Even in this case, the seat heater 1650 and the cover material 1601b can be bonded to the pad material 1601a at the same time in a single work process.

[0124] Eighth embodiment Next, a vehicle seat S8 according to an eighth embodiment will be described with reference to Figs. 28 to 29A and 29B. Incidentally, description of the contents overlapping with those of the above-mentioned vehicle seats S1 to S7 will be omitted. The vehicle seat S8 is equipped with a seat heater inside the seat body, and is designed so as not to affect the thermostat of the seat heater even when the padding material and the covering material are fixed with adhesive.

[0125] The vehicle seat S8 includes a seat cushion 1701, a seat back 1702, and a seat heater 1750 attached inside the seat cushion 1701. In the seat cushion 1701, the padding material 1701a and the cover material 1701b are bonded together by an adhesive portion 1760.

[0126] The seat heater 1750 is attached to the surface of the padding 1701a. As shown in FIG. 29A, the seat heater 1750 has a sheet-shaped sheet base material 1751, electric wires 1752 attached to the sheet base material 1751 and connected to a power source (not shown), a heater wire 1753 connected to the electric wire 1752, and a thermostat 1754 (temperature adjustment device) connected to the electric wire 1752 and the heater wire 1753.

[0127] The thermostat 1754 is disposed at a position different from the interior of the seat cushion 1701 (the padding 1701a). Specifically, the thermostat 1754 is disposed outside the seat cushion 1701 and at a position rearward of the seat cushion 1701 . By doing so, even when the padding material 1701a and the covering material 1701b are bonded to each other by heating and melting the adhesive portion 1760, the thermostat 1754 is not affected. That is, even if the padding material 1701a and the covering material 1701b are fixed with an adhesive, a vehicle seat that is designed not to affect the thermostat 1754 can be realized.

[0128] The thermostat 1754 may be disposed inside the seat cushion 1701 at a position away from the adhesive portion 1760. For example, as shown in FIG. 29B, the thermostat 1754 may be attached to the cushion frame 1710 (side frame 1711), or may be attached on a connecting clip 1715 provided on a plurality of elastic springs 1714.

[0129] <Ninth embodiment> Next, a vehicle seat S9 according to a ninth embodiment will be described with reference to FIG. 30 and FIGS. 31A to 31D. Incidentally, description of the contents overlapping with those of the above-mentioned vehicle seats S1 to S8 will be omitted. The vehicle seat S9 is equipped with an airbag device inside the seat body, and is a seat that is designed so as not to affect the inflation and deployment of the airbag even when the padding material and the covering material are fixed with adhesive.

[0130] The vehicle seat S9 includes a seat cushion 1801, a seat back 1802, and a side airbag device 1850 attached to the inside of a side portion 1802B of the seat back 1802. In the seat back 1802 , the padding material 1802 a and the covering material 1802 b are bonded by an adhesive portion 1860 .

[0131] As shown in FIG. 31A, the side airbag device 1850 is configured so that, when an impact is applied from the side of the vehicle body, a folded airbag 1852 inflates and deploys toward the front side of the seat. The side airbag device 1850 is provided inside the padding material 1802 a in the side portion 1802 B of the seat back 1802 , and includes an airbag module 1851 attached to the outer surface of the back side frame 1821 .

[0132] The airbag module 1851 has an airbag 1852 that inflates and deploys toward the front side of the seat, an inflator 1853 that supplies gas to the inside of the airbag 1852, and a harness (not shown) that is connected to the inflator 1853 and supplies ignition power to the inflator 1853. The harness is connected to a vehicle battery (not shown) disposed on the vehicle body.

[0133] In the above configuration, when the airbag 1852 is inflated and deployed, the pad material 1802a is divided into an inner pad 1802ab and an outer pad 1802ac at the pad through hole 1802aa as a branching point and deployed. When the airbag 1852 is inflated and deployed, the skin 1802b is separated at the skin cleavage portion 1802ba as a branch point into an inner skin 1802bb and an outer skin 1802bc, and deployed. Therefore, the direction in which the airbag expands and deploys can be stabilized.

[0134] In the above configuration, as shown in FIG. 31A, the adhesive portion 1860 (adhesive region) is arranged on the skin 1802b at a position that avoids the skin tear portion 1802ba and the periphery of the skin tear portion 1802ba. In this way, a vehicle seat can be realized that is designed not to affect the inflation and deployment of the airbag 1852 even when the padding material 1802a and the covering material 1802b are fixed with an adhesive.

[0135] In the above configuration, the adhesive portion 1860 is formed along the extending direction (vertical direction) of the skin tearing portion 1802ba, and is disposed at a position sandwiching the skin tearing portion 1802ba in the sheet width direction. This allows the skin material 1802b to be hardened by the adhesive around the skin tearing portion 1802ba, which further prevents the skin material 1802b from tearing at an unintended position when the airbag 1852 is deployed.

[0136] In the above configuration, when the side airbag device 1850 is provided with a guide member (weave cloth) that guides the deployment direction of the airbag 1852, it is preferable that the adhesive portion 1860 is disposed at a position that avoids the portion of the skin material 1802b where the guide member is sewn. By doing so, the direction in which the airbag 1852 deploys can be made more stable.

[0137] 31B, when the side airbag device 1850 includes guide members 1854a, 1854b (inner webbing, outer webbing), the guide member 1854a may be adhered to the padding material 1802a by an adhesive portion 1860. This allows for greater freedom in the method of fixing the guide member 1854a. More specifically, generally, one end of the guide member 1854a is sewn to the skin tearing portion 1802ba, and the other end is attached to the back frame 1820. On the other hand, in this embodiment, the other end of the guide member 1854a is attached to the padding material 1802a, not to the back frame 1820. This increases the degree of freedom in arranging the guide member 1854a.

[0138] In the above configuration, as shown in FIG. 31B, of both ends of the guide member 1854a, only the other end located opposite the skin tearing portion 1802ba (weak portion) may be adhered to the padding material 1802a. By doing so, the area bonded by the adhesive portion 1860 can be minimized, and the amount of adhesive to be applied can be reduced.

[0139] In the above configuration, as shown in FIG. 31C, it is preferable that the guide member 1854a is adhered by an adhesive portion 1860 over the entire surface from one end located on the skin tearing portion 1802ba (weak portion) side to the other end. This allows the guide member 1854a to be firmly attached to the padding material 1802a, and the direction in which the airbag 1852 deploys can be made more stable.

[0140] In the above configuration, as shown in FIG. 31D, padding 1802a and guide member 1854a may be bonded to each other by adhesive portion 1860A, and guide member 1854a and cover material 1802b may be bonded to each other by adhesive portion 1860B. This allows the guide members 1854 to be firmly attached to the padding material 1802a and the covering material 1802b, respectively, and as a result, the deployment direction of the airbag 1852 can be further stabilized.

[0141] In the above configuration, when the skin material 1802b is formed by welding a plurality of skin pieces, it is preferable that the welding line and the skin tearing portion 1802ba (weak portion) are formed at different positions. By doing so, even if the covering material 1802b made up of a plurality of covering pieces is used, the deployment direction of the airbag 1852 can be stabilized. The skin split portion 1802ba can be formed by embossing or the like.

[0142] Tenth embodiment Next, a vehicle seat S10 according to a tenth embodiment will be described with reference to FIGS. Incidentally, description of the contents overlapping with those of the above-mentioned vehicle seats S1 to S9 will be omitted. The vehicle seat S10 is equipped with an airbag device, and the seat is designed so as not to affect the inflation and deployment of the airbag even when the padding material and the covering material are fixed with an adhesive.

[0143] The vehicle seat S10 includes a seat cushion 1901, a seat back 1902, and an airbag device 1950 attached to a lower portion of the seat cushion. In the seat cushion 1901 , the pad material 1901 a and the cover material 1901 b are bonded together by an adhesive portion 1960 .

[0144] The airbag device 1950 is configured so that, when an external impact is applied, the folded airbag 1952 inflates and deploys upward. The airbag device 1950 includes an airbag 1952 attached to a lower portion of the seat cushion 1901 .

[0145] When the airbag 1952 is inflated and deployed, the pad material 1901a is divided into a front pad 1901ab and a rear pad 1901ac at a slit groove 1901aa (slit hole) formed in the surface of the pad material 1901a as a branching point and deployed. The slit groove 1901aa is formed so as to be elongated in the sheet width direction. In other words, the portion of the pad material 1901a where the slit grooves 1901aa are formed is a portion where the adhesive portion 1960 is not provided.

[0146] With the above configuration, a vehicle seat can be realized that is designed not to affect the inflation and deployment of the airbag 1952, even when the padding material 1901a and the covering material 1901b are fixed with an adhesive. Specifically, as shown in FIG. 33, when the airbag 1952 is inflated and deployed, the pad portion of the pad material 1901a that corresponds to the airbag 1952 rises appropriately.

[0147] <Eleventh embodiment> Next, a vehicle seat S11 according to an eleventh embodiment will be described with reference to FIG. 34, and FIGS. 35A and 35B. Incidentally, description of the contents overlapping with those of the above-mentioned vehicle seats S1 to S10 will be omitted. The vehicle seat S11 has a movable body inside the seat body, and is designed so as not to affect the movement of the movable body even when the padding material and the covering material are fixed with adhesive.

[0148] The vehicle seat S11 includes a seat cushion 2001, a seat back 2002, a lumbar support 2030 attached to a center portion 2002A of the seat back 2002, and a movable body 2040 (side support member) attached to a side portion 2002B of the seat back 2002. In the seat back 2002 , the padding material 2002 a and the cover material 2002 b are bonded together by an adhesive portion 2060 .

[0149] The movable body 2040 is disposed between the padding material 2002 a and the back side frame 2021 in the side portion 2002 B of the seat back 2002 . The movable body 2040 is attached to the front surface of the back side frame 2021 in the folded state. The movable body 2040 is movable to move the side portion 2002B from a "normal position" shown in FIG. 35A to a "protruding position" shown in FIG. 35B.

[0150] The adhesive portion 2060 has a central adhesive portion 2061 arranged in a central portion 2002A of the seat back 2002, and a side adhesive portion 2062 arranged in a side portion 2002B. In other words, the adhesive portion 2060 is formed in the seat back 2002 so as to extend from the central portion 2002A to the side portion 2002B. This makes it possible to prevent wrinkles from occurring in the covering material 2002b when the side portion 2002B is displaced by the movable body 2040.

[0151] The side adhesive portion 2062 is disposed at a position overlapping with the movable body 2040 in the sheet width direction and the up-down direction. The side adhesive portion 2062 is disposed so as to avoid a portion of the side portion 2002B that is likely to be deformed when the movable body 2040 moves (specifically, the portion that is most likely to be deformed). For example, the part of the side portion 2002B that is most susceptible to deformation corresponds to the front end portion of the side portion 2002B. By forming the "non-adhesive region" in this manner, it becomes possible for the side portion 2002B to be smoothly displaced when the movable body 2040 is moved.

[0152] With the above-described configuration, a vehicle seat that is designed not to affect the movement of the movable body 2040, even when the padding material 2002a and the covering material 2002b are fixed with an adhesive, can be realized.

[0153] As shown in FIG. 35A, the adhesive portion 2060 is formed so as to avoid the skin end portion of the skin material 2002b that is hung in the hanging groove 2002C. This allows the skin end portion to expand when the side portion 2002B is displaced by the movable body 2040. In other words, when the movable body 2040 moves, the side portion 2002B can be displaced more smoothly.

[0154] <Twelfth embodiment> Next, a vehicle seat S12 according to a twelfth embodiment will be described with reference to FIGS. Incidentally, description of the contents overlapping with those of the above-mentioned vehicle seats S1 to S11 will be omitted. The vehicle seat S12 is equipped with a cushion length adjustment device inside the seat cushion, and realizes a seat that is designed so as not to affect the movement of the device even when the padding material and the covering material are fixed with adhesive.

[0155] The vehicle seat S12 includes a seat cushion 2101, a seat back 2102, and a cushion length adjustment device 2140 attached to the front portion of the seat cushion 2101. In the seat cushion 2101, the pad material 2101a and the cover material 2101b are bonded together by an adhesive portion 2160.

[0156] The cushion length adjustment device 2140 is a device capable of adjusting the front-rear length of the seat cushion 2101, and is movable to move the seat cushion 2101 from the "normal position" to the "extended position". Specifically, the cushion length adjustment device 2140 has a link mechanism and a winding mechanism. When the seat cushion 2101 is in the “normal position”, the link mechanism is folded and the winding mechanism operates to wind up the front end of the seat cushion 2101. When the seat cushion 2101 is in the “extended position”, the link mechanism is deployed and the winding mechanism operates to unwind the front end of the seat cushion 2101.

[0157] The adhesive portion 2160 has an upper adhesive portion 2161 arranged on the upper surface of the seat cushion 2101 and a front adhesive portion 2162 arranged on the front surface of the seat cushion 2101. The upper adhesive portion 2161 is formed by applying a continuous layer of adhesive. The front adhesive portion 2162 is constructed from spaced, discontinuous applications of adhesive. The upper adhesive portion 2161 and the front adhesive portion 2162 extend longitudinally in the sheet width direction. This makes it possible to prevent wrinkles and sagging from occurring in the cover material 2101b when the seat cushion 2101 is displaced by the cushion length adjusting device 2140.

[0158] With the above configuration, a vehicle seat that is designed not to affect the movement of the cushion length adjustment device 2140, even when the padding material 2101a and the covering material 2101b are fixed with an adhesive, can be realized.

[0159] The cushion length adjustment device 2140 is not limited to one having a link mechanism and a winding mechanism, and may be one having a slide mechanism. Even if the cushion length adjustment device 2140 has a slide mechanism, it is preferable not to apply adhesive to the portion of the covering material 2101b that requires an extension margin. This can prevent wrinkles and sagging from occurring in the cover material 2101b when the seat cushion 2101 is displaced.

[0160] <Thirteenth embodiment> Next, a vehicle seat S13 according to a thirteenth embodiment will be described with reference to FIGS. Incidentally, description of the contents overlapping with those of the above-mentioned vehicle seats S1 to S12 will be omitted. The vehicle seat S13 is equipped with a lumbar support inside the seat back, and is designed so as not to affect the movement of the lumbar support even when the padding and covering materials are fixed with adhesive.

[0161] The vehicle seat S13 includes a seat cushion 2201, a seat back 2202, and a lumbar support 2230 attached to the inside of the seat back 2202. In the seat back 2202 , the padding material 2202 a and the cover material 2202 b are bonded together by an adhesive portion 2260 .

[0162] The lumbar support 2230 is a member that supports the lower back of a seated occupant, and is disposed on the back surface of the support plate 2225 in the center of the lower portion of the seat back 2202. The lumbar support 2230 is a movable member that allows the support plate 2225 and the pad material 2202a to protrude toward the seated occupant.

[0163] The adhesive portions 2260 are applied to the front surface of the seat back 2202, and are arranged at predetermined intervals in the vertical direction. The adhesive portion 2260 extends longitudinally in the sheet width direction.

[0164] The adhesive portion 2260 is disposed so as to avoid a portion of the seat back 2202 that is likely to deform due to the movement of the lumbar support 2230 (specifically, the portion that is most likely to deform). For example, the part of the seat back 2202 that is most susceptible to deformation corresponds to the central part (top) of the lumbar support 2230. By forming the "non-bonded region" in this way, the seat back 2202 can be smoothly displaced when the lumbar support 2230 moves. This can suppress any effect on the seating comfort of the occupant (seater).

[0165] With the above configuration, a vehicle seat that is designed not to affect the movement of the lumbar support 2230, even when the padding material 2202a and the covering material 2202b are fixed with an adhesive, can be realized.

[0166] As shown in FIG. 39, the adhesive portion 2260 may be disposed at a position that overlaps a portion of the seat back 2202 that is deformed when the lumbar support 2230 moves (specifically, the portion that is most deformed). Even in this case, by forming a "non-bonded region" in the portion of the covering material 2202b that requires an extension margin, the seat back 2202 can be smoothly displaced when the lumbar support 2230 moves.

[0167] <Fourteenth embodiment> Next, a vehicle seat S14 according to a fourteenth embodiment will be described with reference to FIG. Incidentally, description of the contents overlapping with those of the above-mentioned vehicle seats S1 to S13 will be omitted. The vehicle seat S14 is equipped with a seat back moving device inside the seat back, and is designed so as not to affect the movement of the seat back moving device even when the padding material and the covering material are fixed with adhesive.

[0168] The vehicle seat S14 includes a seat cushion 2301, a seat back 2302, and a seat back moving device 2340 attached to the inside of the seat back 2302. In the seat back 2302 , the padding material 2302 a and the cover material 2302 b are bonded by an adhesive portion 2360 .

[0169] The seat back moving device 2340 is a device that can rotate the upper part of the seat back 2302 forward. In other words, the seat back 2302 is a folding seat back.

[0170] In the above-described configuration, a skin gather portion 2350 is formed in the skin material 2302b at a position that is the boundary between the upper portion and the lower portion of the seat back 2302. The gathered skin portion 2350 is, for example, a portion of the skin material that is creased by sewing and shrinking it. The adhesive portion 2360 is arranged so as to avoid the gathered portion 2350 of the skin material 2302b. By providing the "non-adhesive region" in the upholstery gather portion 2350 in this manner, the seat back 2302 can be smoothly displaced (the upholstery gather portion 2350 contracts) when the seat back moving device 2340 is moved. In other words, it is possible to prevent the upholstery material 2302b from having irregular wrinkles, and the appearance of the vehicle seat can be maintained.

[0171] With the above-described configuration, a vehicle seat that is designed not to affect the seat back movable device 2340 even when the padding material 2202a and the covering material 2302b are fixed with an adhesive can be realized.

[0172] In the above embodiment, a vehicle interior part (vehicle seat) used in an automobile has been described as a specific example, but the present invention is not particularly limited and can be used for a motorcycle interior part (motorcycle seat) and a vehicle interior part (vehicle seat) for a train, a bus, etc. Alternatively, the present invention can be used for a vehicle interior part (vehicle seat) for an airplane, a ship, etc.

[0173] In the above embodiment, the invention is described as a vehicle interior part (vehicle door lining), but the invention may also be a method for manufacturing a vehicle interior part. For example, the invention may be a method for manufacturing a vehicle interior part that includes the steps of attaching a light-emitting member that emits light toward the inside of the vehicle to a base material of the vehicle interior part, attaching a power-generating member that is electrically connected to the light-emitting member and supplies electricity to the light-emitting member, and attaching a storage member that is electrically connected to the light-emitting member and the power-generating member and stores electricity. In this case, it is preferable that the power generating member is in the form of a sheet or film and is disposed along the surface of the vehicle interior part. The above method makes it possible to manufacture a vehicle interior part that can provide lighting function within the vehicle interior even without being supplied with electricity from a power source in the vehicle body.

[0174] In the present embodiment, the vehicle interior part (vehicle door lining) and the vehicle seat according to the present invention have been mainly described. However, the above embodiment is merely an example for facilitating understanding of the present invention, and is not intended to limit the present invention. The present invention can be modified or improved without departing from the spirit of the present invention, and the present invention naturally includes equivalents thereof. In particular, the arrangement and configuration of the light emitting members, power generating members, and power storing members described in the above embodiment are merely examples and do not limit the present invention.
