In the present embodiment, as shown in an enlarged view in FIG. 3, the side part outer piece 16 a (14 a) and the side part inner piece 16 b (14 b) are folded and abutted on the surface of the seat pad 11. It is sutured. Further, the side portion outer piece 16 a (14 a) and the hook portion skin material 20 (18) are overlapped and stitched via a bead member 22. Usually, the flexible organic EL panel has a portion that cannot be displayed at the edge of the displayable portion, and therefore it is preferable to sew the portion that cannot be displayed as a seam allowance.

  Further, as shown in FIG. 4, the end portions of the side portion outer piece 16a (14a) made of a flexible organic EL panel and the side portion inner piece 16b (14b) made of a cloth-like material are overlapped and stitched. The stitched portion may be inserted into a recess formed in the seat pad. A bead does not necessarily have to be interposed between the side portion outer piece 16a (14a) and the scab portion skin material 20 (18).

  In the seat cushion according to the present embodiment, the seat pad is covered with the seat cushion cover 30 on the upper surface and the side surface, and the lower surface is configured not to be exposed by a resin shield (not shown) provided at the lower portion of the seat. Yes. Therefore, as shown in FIG. 1, the seat cushion cover 30 is formed in a bag shape that can cover the upper surface and side surfaces of the seat pad. The seat cushion cover 30 is roughly classified as a substantially flat surface at the center of the upper surface, and a seat surface portion skin material 32 which becomes a seat surface in a normal seating posture, and side portions slightly inclined upward on both sides of the upper surface. 3 of the seat surface side skin materials 34 and 36 constituting the seat cushion, and the skin portion skin material 38 constituting the side surface of the seat cushion, these skin material pieces are stitched and integrated, and the seat pad The shape conforms to a three-dimensional shape. A bead member 42 is interposed between the seat surface portion skin material 32 and the seat surface side portion skin materials 34 and 36 and the scab portion skin material 38. Each of these skin material pieces is formed by stitching a plurality of small pieces. As shown in FIG. 6, the seat surface portion skin material 32 includes two small pieces 32a and 32b, front and rear small pieces 32a and 32b, and a seat surface side portion skin.

  In the present embodiment, among the three small pieces constituting the seat surface side portion skin materials 34 and 36, the outermost side portion outer pieces 34a and 36a are made of a flexible organic EL panel. The two small pieces 34b, 34c, 36b, 36c inside the seat surface side portion skin materials 34, 36, the seat surface portion skin material 32, and the hook portion skin material 38 are made of a conventional cloth-like material. Therefore, as is clear from FIG. 1, a flexible organic EL panel is arranged along both edges of the upper surface of the seat cushion, which is hardly contacted when the seated person sits in a normal posture. It is part of the surface position that defines the outer shape of the sheet.

  The organic EL panel constituting a part of the seat back cover 10 and the seat cushion cover 30 can emit light by using the battery 50 (FIG. 7) as a power source. The design of the seat back cover 10 and the seat cushion cover 30 can be changed by switching the emission color, the display pattern, and the like. That is, as shown in FIG. 7, the organic EL panel 60 (14a, 16a, 34a, 36a) is electrically connected to a panel control ECU (electronic control unit) 62 that controls light emission of the organic EL panel. . The panel control ECU 62 is provided with a panel display selection switch 64 for switching a light emission mode such as a light emission color and a display pattern of the organic EL panel 60 as a part thereof. Can be switched. In addition, the organic EL panel 60 is configured to control on / off of light emission and switching of light emission modes such as a display color and a display pattern corresponding to opening / closing of the door of the vehicle. That is, the panel control ECU 62 is electrically connected to the body ECU 68 directly or via the seat control ECU 70 that controls the front / rear slide of the seat, and the door opening / closing signal detected by the body ECU 68 is sent to the panel control ECU 62. Communicated. The panel control ECU 62 switches the light emission mode of the organic EL 60 in response to the received door opening / closing signal.

According to the sheet having the above configuration, the following operational effects can be obtained.
Since part of the seat cover (the seat back cover 10 and the seat cushion cover 30) is composed of an organic EL panel, the organic EL panel can be easily arranged on the outer surface of the seat by covering the seat cover with the seat pad. Can do. At this time, since the organic EL panel is flexible, it can conform to the outer shape of the sheet. And since the light emission mode of the organic EL panel can be switched, the design image such as the color pattern of the sheet can be easily changed without replacing the seat cover.

  In addition, since the organic EL panel is flexible and can be sewn in the same way as a conventional cloth-like material, the component piece of the conventional seat cover is replaced with the flexible organic EL panel with the same shape as it is. It is also possible to create it.

  Further, since the organic EL panel is disposed at a position where the seated person is hardly in direct contact when sitting in a normal posture, it is possible to prevent the organic EL panel from being deteriorated due to friction during sitting. . Since there is almost no direct contact in the normal posture state, the seated person hardly feels discomfort due to the difference in touch with the cloth-like material used for the other component pieces. The organic EL panel constitutes a part of the surface position that defines the outer shape of the sheet. For example, if light is emitted when getting on and off, the visibility of the sheet position in a dark place can be improved.

The present invention is not limited to the above-described embodiment, and various other embodiments can be considered without departing from the gist of the present invention.
The present invention can be applied not only to the seat back cover 10 and the seat cushion cover 30 but also to a seat cover as a skin of a headrest.
