Description

[Technical field]

[0001] The present invention relates to a vehicle interior skin and a vehicle seat, and more particularly to a vehicle interior skin including a skin material and a cushion layer, and a vehicle seat including a vehicle interior skin. [Background technology]

[0002] Conventionally, flexible materials have been used for the skin covering the padding material in order to conform to the deformation of the padding material. In conventional skins, in order to suppress wrinkles caused by distortion of the skin when cutting, a soft foam layer with cushioning properties is attached to the back side of the flexible skin material, making it difficult for distortion to occur when cutting.

[0003] For example, the skin described in Patent Document 1 is formed in a three-layer structure having a skin material, a soft foam layer provided on the skin material, and a base fabric attached to the back surface of the soft foam layer. In this skin, the skin material, the soft foam layer, and the base fabric are integrated together to appropriately suppress the stretch of the skin material, making it difficult for the skin to warp when cut.

[0004] [Patent Document 1] Japanese Utility Model Application Publication No. 2-40526 Summary of the Invention [Problem to be solved by the invention]

[0005] The skin described in Patent Document 1 is made up of a skin material made of fabric material such as tricot or knit, a soft foam layer made of polyurethane foam, and a base fabric made of polyester, which are laminated together. Therefore, the skin is made up of different materials such as polyurethane and polyester. However, when the skins are made of different materials, they must be separated by material when they are removed from the padding and discarded, which requires time and effort.

[0006] The present invention has been made in view of the above problems, and an object of the present invention is to provide a vehicle interior skin and a vehicle seat provided with a vehicle interior skin that improves cushioning properties and recyclability while suppressing the occurrence of wrinkles. [Means for solving the problem]

[0007] The above problem is solved by the vehicle interior skin of the present invention, which provides a vehicle interior skin covering the surface of a padding material, comprising a skin material forming a surface, and a cushion layer provided on the surface of the skin material facing the padding material, the cushion layer having a stretch layer having elasticity and provided on the surface of the skin material facing the padding material, and a nonwoven fabric provided on the surface of the stretch layer facing the padding material and disposed opposite the padding material, and the skin material, the stretch layer and the nonwoven fabric are each made of the same material. With the above-mentioned configuration, the skin material, the stretch layer, and the nonwoven fabric are all made of the same material, so there is no need to separate them when disposing of the skin. In addition, the provision of the stretch layer can prevent wrinkles. In addition, the provision of the nonwoven fabric can improve cushioning properties. Therefore, it is possible to improve cushioning properties and recyclability while suppressing the occurrence of wrinkles.

[0008] In this case, the skin material, the stretch layer and the nonwoven fabric are preferably made of polyester fiber. With the above-mentioned configuration, by using polyester fiber as the material for the vehicle interior skin, it is possible to appropriately suppress the elongation of the fiber and further suppress wrinkles.

[0009] In this case, it is preferable that the stretch layer is disposed at a position corresponding to at least the corners of the pad material. With the above-mentioned configuration, the stretch layer having elasticity is provided at the corners of the padding material where wrinkles tend to occur, so that the occurrence of wrinkles can be further suppressed.

[0010] In this case, it is preferable that the nonwoven fabric is disposed at least at a position corresponding to the seating surface of the pad material. With the above-mentioned configuration, the cushioned nonwoven fabric is provided on the seating surface of the pad material, thereby improving the sitting comfort of the seated person.

[0011] In this case, the pad has an engaging portion that engages with an engaged portion provided on the pad material and is used to suspend the skin material, and the engaging portion is preferably made of the same material as the skin material, the stretch layer and the nonwoven fabric. With the above-mentioned configuration, even if the skin is provided with an engaging portion for hanging the skin material, the skin material and the engaging portion are made of the same material, so that separation is not required when disposing of the skin.

[0012] In this case, the engaging portion may be a hook or loop portion of a hook-and-loop fastener. With the above-mentioned configuration, the engagement strength of the cover to the pad material can be increased.

[0013] In this case, the skin material, the stretch layer and the nonwoven fabric are sewn together with a sewing thread, and the sewing thread is preferably made of polyester fiber. With the above-mentioned configuration, the cover material, the stretch layer, the nonwoven fabric and the sewing thread are each made of polyester fiber, so that separation is not required when disposing of the cover.

[0014] The above problem is solved by the vehicle seat equipped with a vehicle interior skin of the present invention, which comprises a frame, the padding material placed on the frame, the vehicle interior skin covering a surface of the padding material, and a blower device provided on the frame, wherein an air passage portion is formed in the padding material through which air blown out from the blower device passes, and at least a portion of the vehicle interior skin is positioned at a position overlapping the air passage portion in the thickness direction of the padding material. With the above-mentioned configuration, the provision of the highly breathable nonwoven fabric enhances the breathability of the portion of the cover that overlaps the air passage, making it easier for air passing through the air passage to be delivered to the seated occupant, and enabling air to be delivered appropriately to the seated occupant.

[0015] The above-mentioned problem is solved by the vehicle seat equipped with a vehicle interior skin of the present invention, which comprises a frame, the padding material placed on the frame, and the vehicle interior skin covering a surface of the padding material, in which a temperature adjustment section is provided in the padding material, and at least a portion of the vehicle interior skin is positioned in a position where it overlaps with the temperature adjustment section in the thickness direction of the padding material. With the above-mentioned configuration, the nonwoven fabric is thinner than a base material such as a soft foam, so that the surface is thin, which makes it easier for heat from a heater or the like to be transferred to the seated person, thereby allowing the seated person to be appropriately warmed.

[0016] The above problem is solved by the vehicle seat equipped with a vehicle interior skin of the present invention, which comprises a frame, the padding material placed on the frame, and the vehicle interior skin covering a surface of the padding material, wherein the padding material is provided with a notification portion, and at least a portion of the vehicle interior skin is positioned in a position that overlaps with the notification portion in the thickness direction of the padding material. With the above-mentioned configuration, the nonwoven fabric is thinner than a base material such as a soft foam, so that the surface is thin, which makes it easier to transmit vibrations from the vibration device to the seat occupant and appropriately notify the seat occupant of information.

[0017] The above-mentioned problem is solved by the vehicle seat equipped with a vehicle interior skin of the present invention, which comprises a frame, the padding material placed on the frame, and the vehicle interior skin covering a surface of the padding material, in which a detection unit is provided on the padding material, and at least a portion of the vehicle interior skin is positioned in a position where it overlaps with the detection unit in the thickness direction of the padding material. According to the above-mentioned configuration, the nonwoven fabric is thinner than a base material such as a soft foam, so that the surface is thin, thereby improving the detection sensitivity of a seating sensor or the like. Effect of the Invention

[0018] According to the present invention, it is possible to improve cushioning properties and recyclability while suppressing the occurrence of wrinkles. Furthermore, according to the present invention, it is possible to appropriately suppress the elongation of the fibers and further suppress wrinkles, and it is also possible to improve the durability and quick-drying properties of the skin for vehicle interiors. Furthermore, according to the present invention, the occurrence of wrinkles can be further suppressed. Furthermore, according to the present invention, the sitting comfort of the seat occupant can be improved. Furthermore, according to the present invention, separation of the skins is not required when they are disposed of. Furthermore, according to the present invention, the strength of engagement of the cover with the padding material can be increased. Furthermore, according to the present invention, air can be appropriately delivered to a seated occupant. Furthermore, according to the present invention, a seated occupant can be appropriately warmed. Furthermore, according to the present invention, information can be appropriately notified to a seated occupant. Furthermore, according to the present invention, the detection sensitivity of a seating sensor or the like can be improved. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] Hereinafter, an embodiment of the present invention will be described with reference to FIGS. In the following description, the "front-rear direction" refers to the front-rear direction of the vehicle seat, which coincides with the direction of travel when the vehicle is traveling. The "seat width direction" refers to the width direction of the vehicle seat, which coincides with the left-right direction as seen by an occupant seated in the vehicle seat. The "up-down direction" refers to the up-down direction of the vehicle seat, which coincides with the vertical direction when the vehicle is traveling on a horizontal plane.

[0021] <Overall sheet configuration> The vehicle seat S of this embodiment is a seat that is placed on a vehicle body floor and in which a vehicle occupant sits, as shown in Fig. 1. In this embodiment, the vehicle seat S is used as a front seat that corresponds to the front seat of the vehicle. However, the present invention is not limited to this, and the vehicle seat S may be a rear seat of the vehicle, and may also be used as a second-row middle seat or a third-row rear seat in a vehicle that has three rows of seats in the front-rear direction.

[0022] 1 and 2, the vehicle seat S is mainly composed of a seat body having a seat back 1, a seat cushion 2, and a headrest 3. The vehicle seat S also includes an airbag device 4 provided on a seat frame F, a detection unit 5 attached inside the seat body and detecting a biological signal of an occupant seated in the seat body, a notification unit 6 that applies vibrations to the occupant, a blower device 7 that blows air toward the occupant, a temperature adjustment unit 8 that adjusts the temperature of the seating surface, and a seat movable unit 9 that operates to project a part of the seat body toward the occupant from a normal position. The vehicle seat S is provided with a seat frame F therein. The seat back 1 and the seat cushion 2 each have a padding material P arranged on the seat frame F and a skin T covering the padding material P.

[0023] As shown in Figures 1 and 2, the seat back 1 is a backrest portion that supports the back of an occupant from behind, and is constructed by placing a padding material P on a back frame Fa that forms the skeleton of the seat back 1 and covering it with a skin T. The seat cushion 2 is a seating portion that supports an occupant from below, and is configured by placing a pad material P on a cushion frame Fb that forms the skeleton of the seat cushion 2, and covering it with a skin T. The headrest 3 is a head portion that supports the head of an occupant from behind, and is configured by placing a pad material P on a pillar (not shown) that serves as a core material, and covering it with a skin T.

[0024] As shown in FIG. 2, the airbag device 4 has a known structure, is attached to a seat frame F, and has an airbag and an inflator. The airbag device 4 is disposed inside the seat back 1, on the inner side of the skin T. When gas is ejected by the inflator and the airbag expands outward from the case, the padding P breaks at the tear line 4a, and the skin T is cut open, causing the airbag to deploy outward. The airbag device 4 may be provided in the seat cushion 2.

[0025] As shown in Figs. 2 to 4, the detection unit 5 is a sheet-shaped pressure sensor that detects the seating pressure applied to the seating surfaces of the seat back 1 and the seat cushion 2 when a person sits on the seat. Here, the "seating pressure" is a value that periodically changes in response to the physiological activity, specifically breathing, of an occupant when the occupant is seated on the seat back 1 and the seat cushion 2, and is a target value detected by a pressure sensor. In other words, it corresponds to the "biological signal (biological information) of the seated occupant." The detection unit 5 is a push switch type seating sensor that turns on or off depending on the seating pressure of a seated person, but is not limited to this. For example, the detection unit 5 may be a pulse wave sensor or a blood pressure sensor.

[0026] 2, the notification unit 6 is provided on the pad material P and notifies the seated occupant of information. Specifically, the notification unit 6 is a vibration device equipped with a vibration motor that applies a physical force to the seated occupant, and the notification unit 6 notifies the seated occupant of information by applying vibrations. The notification unit 6 may be a light emitting device such as a light that notifies information by light, or may be a sound emitting device that notifies information by sound.

[0027] The notification unit 6 is provided on the pad material P, and has a vibration unit 6a provided in the center of the seat back 1 and a side vibration unit 6b provided on a side of the seat back 1. The vibration unit 6a and the side vibration unit 6b can provide a stimulus to the back of the seated occupant. The notification unit 6 may be provided on the seat cushion 2. In this case, the notification unit 6 can provide a stimulus to the buttocks of the seated occupant.

[0028] 2 and 3, the blower device 7 is provided on each seat frame F of the seat back 1 and the seat cushion 2. The blower device 7 has a blower body 7a that blows out air and a duct 7b through which the air passes. The blower body 7a is attached to the cushion frame Fb of the seat cushion 2. The duct 7b is attached to each seat frame F of the seat back 1 and the seat cushion 2. The air blown out from the blower body 7a passes through the duct 7b and is sent to each of the seat back 1 and the seat cushion 2. The blower body 7a may be provided in each of the seat frames F of the seat back 1 and the seat cushion 2, respectively.

[0029] As shown in Figs. 2 to 4, the temperature adjustment unit 8 is provided between the surface T and the padding P of the seat back 1 and the seat cushion 2, and is a device that adjusts the temperature of the seat back 1 and the seat cushion 2. For example, the temperature adjustment unit 8 includes a temperature sensor (e.g., a thermistor), a heating element (e.g., a heater) for heating the seat, and a cooling element (e.g., a Peltier element) for cooling the seat. The temperature adjustment unit 8 switches the heating element and the cooling element ON / OFF according to the temperature detected by the temperature sensor and a preset target temperature, and operates to bring the temperature of the seat of the seat back 1 closer to the preset target value.

[0030] 5A and 5B, the seat movable part 9 is an electrically-operated device that operates to protrude the seat back 1 and the seat cushion 2. The seat movable part 9 is, for example, a movable body having an air cell, and is provided on the pad material P. The air cells of the seat movable part 9 expand toward the occupant (seat occupant) side by filling them with compressed air, and protrude from the normal position (Fig. 5A) to the protruding position (Fig. 5B). Then, the air cells of the seat movable part 9 contract as the filled compressed air is discharged, and return to the normal position.

[0031] Further, the vehicle seat S has an engagement member 10 for suspending the cover T onto the pad material P, as shown in FIG. The engaging member 10 is a strip-shaped hook-and-loop fastener, and has an engaging portion 11 provided on the cover T, and an engaged portion 12 provided on the padding material P and engaged with the engaging portion 11. The cover T is fixed to the padding material P by the engaging portion 11 engaging with the engaged portion 12 and being suspended. In addition, a groove Pd of the pad material P, which will be described later and is provided at a position corresponding to the airbag device 4, is provided with a clip member having an engagement force weaker than that of a hook-and-loop fastener.

[0032] 6, the engaging portion 11 is a hook portion of a hook-and-loop fastener for hanging up the skin T (specifically, the skin material 20 described later). The engaging portion 11 engages with an engaged portion 12 provided on the pad material P. The engaging portion 11 may be a loop portion of a hook-and-loop fastener.

[0033] The engaging portion 11 is made of resin, for example, polyester resin such as polyethylene terephthalate (PET), etc. Alternatively, it may be made of polypropylene, polyethylene resin, etc. The engaging portion 11 extends longitudinally along the hanging end of the skin T, and is sewn together with the skin T by a sewing thread ST made of polyester fiber.

[0034] 6, the engaged portion 12 is a loop portion for hooking the engaging portion 11. The engaged portion 12 is provided inside the groove portion Pd of the padding material P. The engaged portion 12 may be a hook portion of a hook-and-loop fastener.

[0035] The engaged portion 12 is made of resin, and is formed of, for example, polyurethane (PU) resin. It may also be formed of polypropylene (PP) resin, polyacetal (POM) resin, polyamide (PA) resin, polycarbonate (PC) resin, or the like. The engaged portion 12 is formed integrally with the pad material P made of polyurethane, for example, during foam molding, and is attached to the pad material P with a part of the engaged portion 12 embedded inside the pad material P.

[0036] <Eidermis> 1 and 2, the skin T (skin for vehicle interior) is attached to cover a padding material P provided on a vehicle seat S in a stretched state with a predetermined tension applied thereto. The skin T is fixed to the padding material P by having an engaging portion 11 engaged with an engaged portion 12 and hung thereon. In this embodiment, an example will be described in which the vehicle interior skin is a skin T that covers a padding material P of a vehicle seat S. However, the present invention is not limited to this, and the vehicle interior skin may be a skin that covers a padding material provided on a vehicle door.

[0037] As shown in FIG. 6, the cover T has a laminated structure and includes a cover material 20 that forms the surface of the vehicle seat S, and a cushion layer 30 provided on a rear surface 20a of the cover material 20 on the pad material P side. The cushion layer 30 is provided on the entire surface of the rear surface 20a of the skin 20. The cushion layer 30 may be provided on only a part of the rear surface 20a of the skin 20.

[0038] The cover material 20 is provided so as to be located on the front side (the exposed side facing the seat occupant) in the thickness direction of the cover T, and is a covering material that constitutes the external appearance of the vehicle seat S. The skin material 20 is formed using threads made of polyester fibers. Examples of polyester fibers include polyethylene terephthalate (PET), polytrimethylene terephthalate (PTT), polybutylene terephthalate (PBT), polybutylene naphthalate (PEN), polybutylene naphthalate (PBN), polypropylene (PP), polylactic acid (PLA), etc. By using polyester fiber threads, it is possible to increase abrasion resistance.

[0039] The cushion layer 30 is provided so as to be located on the back side (the side facing the padding material P) of the skin T in the thickness direction. The cushion layer 30 is provided on the back surface 20a of the skin material 20 facing the pad material P, and includes a stretch layer 31 having elasticity, and a nonwoven fabric 32 provided on the back surface 31a of the stretch layer 31 facing the pad material P, and arranged opposite the pad material P.

[0040] The stretch layer 31 is a base fabric having elasticity (stretchability) and is formed using yarns made of polyester fibers. Examples of polyester fibers include polyethylene terephthalate (PET), polytrimethylene terephthalate (PTT), polybutylene terephthalate (PBT), polybutylene naphthalate (PEN), polybutylene naphthalate (PBN), polypropylene (PP), polylactic acid (PLA), etc. By using polyester fiber yarns, it is possible to increase abrasion resistance.

[0041] The stretch layer 31 is disposed at a position corresponding to the corner of the padding material P. Specifically, as shown in Fig. 2, the stretch layer 31 is disposed at a corner portion C in the side portion of the seat back 1 and at a corner portion C between the center portion and the side portion of the seat back 1. In this way, since the stretch layer 31 having elasticity is provided at least at the corners of the padding material P, it is possible to suppress the occurrence of wrinkles in the skin T when the skin T is hung in the padding material P. Note that the stretch layer 31 may be disposed only at positions corresponding to the corners of the padding material P.

[0042] The nonwoven fabric 32 is, for example, a needle-punched nonwoven fabric having cushioning properties, and is made of polyester fibers. Examples of polyester fibers include polyethylene terephthalate (PET), polytrimethylene terephthalate (PTT), polybutylene terephthalate (PBT), polybutylene naphthalate (PEN), polybutylene naphthalate (PBN), polypropylene (PP), polylactic acid (PLA), etc. By using polyester fiber threads, it is possible to increase abrasion resistance.

[0043] The nonwoven fabric 32 is disposed at a position corresponding to the seating surface of the pad material P. In this manner, the cushioning nonwoven fabric 32 is provided at least on the seating surface of the pad material P, thereby improving the seating comfort. Note that the nonwoven fabric 32 may be disposed only at a position corresponding to the seating surface of the pad material P.

[0044] The skin material 20, the stretch layer 31 and the nonwoven fabric 32 are sewn together with sewing thread ST to form the skin T. The sewing thread ST is made of polyester fibers, such as polyethylene terephthalate (PET), polytrimethylene terephthalate (PTT), polybutylene terephthalate (PBT), polybutylene naphthalate (PEN), polybutylene naphthalate (PBN), polypropylene (PP), polylactic acid (PLA), etc.

[0045] In this manner, the skin T has a three-layer structure of the skin material 20, the stretch layer 31 having elasticity, and the nonwoven fabric 32 having cushioning properties, and therefore can enhance cushioning properties while suppressing wrinkles. Furthermore, by using polyester fibers, the abrasion resistance and quick drying properties of the surface can be improved.

[0046] <Pad> The padding material P has a cushion portion formed of a foam, and the cushion portion is covered with a skin T. As the foam, polypropylene bead foam, polyethylene bead foam, polypropylene foam, polyethylene foam, acrylonitrile-styrene foam, ethylene vinyl acetate copolymer resin, urethane foam material, or a combination of these may be used. In this embodiment, the padding material P is a polyurethane pad formed by foam molding using a urethane foaming agent.

[0047] As shown in FIG. 2, the padding P is provided with the seat components (the airbag device 4, the detection unit 5, the notification unit 6, the blower device 7, the temperature adjustment unit 8, and the seat movable unit 9). In addition, a rubber member R is provided on the seating surface side of the detection unit 5 and the notification unit 6 to improve seating comfort.

[0048] As shown in FIG. 3, the pad material P has a pad main body Pa, a passage forming portion Pb in which an air passage portion 40 is formed through which the air blown from the blower device 7 passes, and a sensor mounting portion Pc in which the detection portion 5 is attached. 8, a long groove portion Pd for suspending the skin T is formed in the pad material P. A plurality of groove portions Pd are formed in each of the pad materials P of the seat back 1 and the seat cushion 2. Note that the number and arrangement of the groove portions Pd are merely examples and are not limited thereto.

[0049] The pad body Pa is provided with an outlet port Pa1 through which air sent out from the duct 7b of the blower device 7 is blown out. In the passage forming portion Pb, an air passage portion 40 is formed, which passes the air sent out from the air outlet Pa1 toward the surface T. The air passage portion 40 is formed in a predetermined arrangement pattern, and a plurality of air passage portions 40 are formed over the entire seating surface. The pad material P is made of polyurethane and has overall breathability, so that it is possible for air to pass through the entire pad material P except for the air passage portion 40. A plurality of detection units 5 are attached to the sensor attachment unit Pc. In addition, a temperature adjustment unit 8 is disposed above the sensor attachment unit Pc.

[0050] <Materials for vehicle seat components> Here, the materials of the components of the vehicle seat S will be described with reference to FIG. The seat frame F on which the padding P is arranged is made of a metal having rigidity, such as steel, aluminum alloy, or magnesium alloy. The padding material P is made of a material different from the seat frame F and the cover T. Specifically, the padding material P is made of polyurethane. Moreover, the engaged portion 12 provided on the padding material P is made of the same material as the padding material P. Specifically, the engaged portion 12 is made of polyurethane. The skin T is made of a material different from that of the seat frame F and the padding P. Specifically, the skin T is made of polyester. Moreover, the engagement portion 11 provided on the skin T is made of the same material as the skin T. Specifically, the engagement portion 11 is made of polyester.

[0051] When discarding the vehicle seat S, the seat frame F, the padding P, and the cover T need to be separated because they are made of different materials. At this time, the engaging portion 11 is made of the same material as the cover T, so there is no need to separate the engaging portion 11 from the cover T. In addition, the engaged portion 12 is made of the same material as the padding P, so there is no need to separate the engaged portion 12 from the padding P. This can improve the ease of dismantling the vehicle seat S. Also, the recyclability of the vehicle seat S can be improved.

[0052] In the skin T, the engaging portion 11, the skin material 20, the stretch layer 31, the nonwoven fabric 32 and the sewing thread ST are each made of polyester fiber. In this way, since the engaging portion 11, the skin material 20, the stretch layer 31, the nonwoven fabric 32 and the sewing thread ST are each formed of the same material (polyester), there is no need to separate them when disposing of the skin T. This improves recyclability.

[0053] <Layout of cover, padding and seat components> Next, the arrangement of the cover T, the padding P and the seat constituent members will be described with reference to Figs. 2, 5A and 5B. The cover T is positioned so as to overlap each seat component (airbag device 4, detection unit 5, notification unit 6, blower device 7, temperature adjustment unit 8 and seat movable unit 9) provided on the pad material P or the seat frame F in the thickness direction of the pad material P.

[0054] More specifically, the skin T is disposed at a position where it overlaps with the air passage portion 40 in the thickness direction of the pad material P, as shown in FIG. The surface layer T is provided with nonwoven fabric 32 having high breathability. Therefore, the surface layer T has improved breathability in the portion overlapping with the air passage portion 40, so that air passing through the air passage portion 40 can be easily sent to the seated occupant.

[0055] 2, the skin T is disposed at a position where it overlaps with the detection unit 5 in the thickness direction of the padding material P. The skin T is provided with a nonwoven fabric 32 that is thinner than a base material such as a soft foam. Therefore, since the skin T is formed thin, when a seating sensor is provided as the detection unit 5 in the pad material P, for example, the detection sensitivity of the sensor can be improved.

[0056] 2, the skin T is disposed at a position where it overlaps with the notification portion 6 in the thickness direction of the padding material P. The skin T is provided with a nonwoven fabric 32 that is thinner than a base material such as a soft foam. Therefore, since the skin T is formed thin, when a vibration device is provided on the pad material P as the notification unit 6, for example, the vibration of the vibration device can be appropriately transmitted to the seated person.

[0057] As shown in FIG. 2, the skin T is disposed at a position where it overlaps with the temperature adjusting portion 8 in the thickness direction of the padding material P. The skin T is provided with a nonwoven fabric 32 which is thinner and has lower heat insulation than a base material such as a soft foam. Therefore, since the skin T is formed thin, when a heater is provided in the pad material P as the temperature adjustment unit 8, for example, the heat of the heater can be easily transferred to the seated person.

[0058] Further, the skin T is disposed at a position where it overlaps with the movable seat portion 9 in the thickness direction of the pad material P, as shown in Figs. 5A and 5B. The skin T is provided with a highly elastic stretch layer 31. Therefore, the skin T is easily stretched, and wrinkles are less likely to occur in the skin T when the air cells bulge out as the movable seat portion 9, for example.

[0059] In the above embodiment, a vehicle seat used in an automobile has been described as a specific example, however, without being limited thereto, the present invention can be used for various seats such as two-wheeler seats, vehicle seats for trains and buses, seats for vehicles such as airplanes and ships, as well as office chairs for work, wheelchairs, and child seats in shopping carts.

[0060] In the present embodiment, the vehicle seat according to the present invention has 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.
