[Fig. 2] is a schematic representation of the entire vehicle seat back panel according to the present invention. [Fig. 3] is a schematic representation of the internal structure of the vehicle seat back panel according to the present invention.

[0036] As shown in Figures 1 to 3, the present invention relates to a vehicle seat back panel, comprising a light-transmitting material 10, a CCT (sculpted panel) layer 20 and a light-emitting component 30, the light-emitting component 30 being attached to the back of the light-transmitting material 10, the CCT (sculpted panel) layer 20 being injection molded onto the back of the light-transmitting material 10 such that the light-emitting component 30 is located between the light-transmitting material 10 and the CCT (sculpted panel) layer 20, and the light-transmitting material 10 being a light-transmitting skin or fabric. The CCT (sculpted panel) layer 20 is then mounted on a foam layer 40 of a vehicle seat.

[0037] Preferably, the light-transmitting skin is light-transmitting PVC, light-transmitting PU, or light-transmitting TPO (thermoplastic polyolefin elastomer). The electroluminescent component 30 is preferably an ultra-thin substrate luminescent sheet or an optical fiber, which is bonded to the back of the light-transmitting skin using a transparent spray adhesive.

[0038] Further, a connecting line of the ultra-thin substrate luminescent sheet is attached to a mold using an adhesive tape.

[0039] More preferably, the light-emitting component 30 may be an LED array. The LED array is an LED array that uses an FPC (flexible printed circuit board) as a substrate, and the LED array is bonded to the back of the light-transmitting skin.

[0040] [Fig. 4] is a schematic representation of the overall structure of a vehicle seat panel according to the present invention. [Fig. 5] is a schematic representation of the entire vehicle seat panel according to the present invention.

[0041] As shown in Figures 4 and 5, the present invention further relates to a vehicle seat cover, which is made of a light-transmitting material 10. An electroluminescent component 30 is provided on the back of the material light-transmitting material 10. The light-transmitting material 10 is preferably a light-transmitting skin or fabric.

[0042] In particular, the light-transmitting skin may preferably be light-transmitting PVC, light-transmitting PU, or light-transmitting TPO (thermoplastic polyolefin elastomer). The electroluminescent component 30 may preferably be an ultra-thin substrate luminescent sheet or an optical fiber, which is bonded to the back of the light-transmitting skin using a transparent spray adhesive.

[0043] Preferably, a connection line of the ultra-thin substrate luminescent sheet is fixed on a mold using an adhesive tape.

[0045] According to the above description of the structure, the use of the ultra-thin luminescent sheet made of soft material in the vehicle seat back panel and the cover can ensure the smooth appearance of the back panel and the cover. The use of the LED array with the FPC (flexible printed circuit board) as the substrate can also ensure the smooth appearance of the back panel and the cover. The PVC material having excellent light transmission and a material close to genuine leather is used to ensure that the luminous intensity of the cover and the back panel meets standards thereof. The use of the transparent spray glue to stick the luminescent sheet on the back of the transparent PVC can ensure the luminous effect while preventing the PVC skin from wrinkling.

[0046] In addition, using the adhesive tape to fix the connection line of the luminescent sheet to the mold during the production process can prevent wrinkles and facilitate the connection.

[0047] In addition, the arrangement of the LED array can be defined as follows: before bonding, the LED array is completely covered by an adhesive tape to ensure that a surface of the LED array is smooth, and its bonding step is the same as that of the luminescent sheet. The PVC is firstly mounted on the mold to determine the bonding position, and none of the luminescent sheet, the LED array and the optical fiber can be located at the corner and bent, otherwise the PVC cannot be fixed.

[0048] The present invention further relates to a vehicle seat, comprising a vehicle seat cover as described above, and / or a vehicle seat back panel as described above.
