Abstract

An arrangement for a vehicle, such as the head lamp, includes a part that needs a snow-melting structure, a line heater that is transferred to and mounted on the part, and a power-supplying unit that supplies electric current to the line heater. The line heater includes a base film, an adhesive layer, a line-patterned conductive member, and a resist layer. The adhesive layer is adhered to the part and thereby the line-patterned conductive member is transferred to the part.

Claims

1. An arrangement used in a vehicle, the arrangement comprising:

a part with a snow-melting structure;

a line heater that is transferred to and mounted on the part, the line heater including a base film, an adhesive layer that is mounted on a first surface of the base film, a conductive member that is formed in a line pattern on a second surface of the base film and that generates heat when electric current is supplied, and a resist layer that is mounted on the second surface to cover the conductive member, wherein the base film is at least cut after the manner of the line pattern of the conductive member and the adhesive layer is adhered to the part to transfer line-patterned conductive member to the part; and

a power supplying unit that supplies electric current to the line heater.

2. The arrangement according to claim 1, wherein the line heater constitutes a module component that has plural possible combinations.

3. The arrangement according to claim 1, further comprising a coloring sub-unit.

4. The arrangement according to claim 1, wherein the base film, the adhesive layer, and the resist layer are cut with respect to a width of the conductive member at least in such a width for the resist layer to be able to cover the conductive member.

5. The arrangement according to claim 1, wherein the line heater includes a high-temperature generating sub-unit and a low-temperature generating sub-unit based on a high-or-low difference of a resistance, or includes a heat-generating sub-unit and a heat-non-generating sub-unit based on the presence or absence of the resistance, or includes a high-temperature generating sub-unit and a low-temperature generating sub-unit based on a dense or non-dense condition of the line pattern of the conductive member.

6. The arrangement according to claim 1, wherein the line heater includes a temperature control unit that controls a temperature of heat that the conductive member generates.

7. A line heater unit that is mounted on an arrangement for use in a vehicle, the line heater unit comprising:

a base film;

an adhesive layer that is mounted on a first surface of the base film;

a conductive member that is mounted on a second surface of the base film in a line pattern and that generates heat when electric current is supplied;

a resist layer that is mounted to cover the conductive member on the second surface; and

a separator that is located on the resist layer side, after at least the base film is cut after the manner of the line pattern of the conductive member, the adhesive layer is adhered to the part, and the line-patterned conductive member is transferred to the part, and that is peeled off from the resist layer side.

8. The line heater unit according to claim 7, wherein the line heater unit constitutes a module component that has plural possible combinations.

9. The line heater unit according to claim 7, further comprising a coloring sub-unit.

10. The line heater unit according to claim 7, wherein the base film, the adhesive layer, and the resist layer are cut in such a width, with respect to a width of the conductive paste, that the resist layer can cover at least the conductive member.

11. The line heater unit according to claim 7, wherein the line heater includes a high-temperature generating sub-unit and a low-temperature generating sub-unit based on a high-or-low difference of a resistance, or includes a heat-generating sub-unit and a heat-non-generating sub-unit based on the presence or absence of the resistance, or includes a high-temperature generating sub-unit and a low-temperature generating sub-unit based on a dense or non-dense condition of the line pattern of the conductive member.

12. The line heater unit according to claim 7,-wherein the line heater includes a temperature control unit that controls a temperature of heat that the conductive member generates.

13. The line heater unit according to claim 7, wherein the separator represents, to be able to follow a curved surface of the part, at least one of a separator made of a flexible material, a separator provided with slits, a separator formed after the manner of the line pattern of the conductive member, and a separator three-dimensionally designed with the line pattern of the conductive member and developed.
