Abstract

A decorative component for a vehicle includes a decorative body portion having millimeter wave transmittance and a heating sheet. The decorative body portion is configured to decorate the vehicle by being attached to part of a vehicle on a leading side in a transmitting direction of millimeter waves from a millimeter wave radar device. The heating sheet includes a plastic sheet and a wire-shaped heater provided on the plastic sheet. At least a main portion of the heating sheet is provided integrally with the decorative body portion. The thickness in the front-rear direction is set uniform in at least a transmittance area of millimeter waves in the decorative body portion and the heating sheet.

First claim

The invention claimed is:

1. A decorative component for a vehicle comprising
a decorative body portion having a millimeter wave transmittance, wherein the decorative body portion is configured to be attached to part of a vehicle on a leading side in a transmitting direction of a millimeter wave from a millimeter wave radar device to decorate the vehicle; and
a heating sheet including a plastic sheet and a wire-shaped heater provided on the plastic sheet, wherein
at least a main portion of the heating sheet is provided integrally with the decorative body portion,
in the decorative body portion and the heating sheet, a thickness in a front-rear direction is set uniform in at least a transmittance area of the millimeter wave,
the heating sheet is provided integrally with the decorative body portion only at the main portion,
the heating sheet includes connection terminals arranged in opposite ends of the heater and a connecting portion extending from the main portion to an exterior of the decorative body portion,
the connection terminals are provided in the connecting portion, and
the connecting portion is bent rearward at a boundary with the main portion and extends rearward from a lower end of the main portion.

2. The decorative component according to claim 1 , wherein
the decorative body portion includes
a base member made of a plastic material,
a transparent member made of a plastic material and arranged on a front side of the base member in the transmitting direction, and
a decoration layer provided between the base member and the transparent member and having a millimeter wave transmittance, and

at least the main portion of the heating sheet is arranged to be laminated with one of at least the base member and the transparent member, among the base member, the transparent member, and the decoration layer.

3. The decorative component according to claim 2 , wherein
the transparent member is divided into a front transparent portion and a rear transparent portion located on a rear side of the front transparent portion, and
at least the main portion of the heating sheet is arranged between the front transparent portion and the rear transparent portion to be laminated with the front transparent portion and the rear transparent portion.

4. The decorative component according to claim 2 , wherein at least the main portion of the heating sheet is arranged to be laminated with the base member from a rear side of the base member.

5. The decorative component according to claim 2 , wherein at least the main portion of the heating sheet is arranged between the decoration layer and the base member to be laminated with the decoration layer and the base member.

6. The decorative component according to claim 3 , further comprising a hard coating layer provided on a front surface of the transparent member, wherein the hard coating layer has a hardness greater than that of the transparent member.

7. The decorative component according to claim 4 , further comprising a hard coating layer provided on a front surface of the transparent member, wherein the hard coating layer has a hardness greater than that of the transparent member.

8. The decorative component according to claim 5 , further comprising a hard coating layer provided on a front surface of the transparent member, wherein the hard coating layer has a hardness greater than that of the transparent member.

9. The decorative component according to claim 2 , wherein at least the main portion of the heating sheet is arranged to be laminated with the transparent member from a front side of the transparent member.

10. The decorative component according to claim 9 , wherein the decorative component includes a hard coating layer arranged on a front surface of at least the main portion of the heating sheet, the hard coating layer having a hardness greater than that of the heating sheet.

11. The decorative component according to claim 6 , further comprising a water repellent film provided on a front surface of the hard coating layer.

12. The decorative component according to claim 7 , further comprising a water repellent film provided on a front surface of the hard coating layer.

13. The decorative component according to claim 8 , further comprising a water repellent film provided on a front surface of the hard coating layer.

14. The decorative component according to claim 10 , further comprising a water repellent film provided on a front surface of the hard coating layer.

15. A decorative component for a vehicle comprising
a decorative body portion having a millimeter wave transmittance, wherein the decorative body portion is configured to be attached to part of a vehicle on a leading side in a transmitting direction of a millimeter wave from a millimeter wave radar device to decorate the vehicle; and
a heating sheet including a plastic sheet and a wire-shaped heater provided on the plastic sheet, wherein
at least a main portion of the heating sheet is provided integrally with the decorative body portion,
in the decorative body portion and the heating sheet, a thickness in a front-rear direction is set uniform in at least a transmittance area of the millimeter wave,
the heating sheet includes connection terminals arranged in opposite ends of the heater and a connecting portion extending from the main portion to an exterior of the decorative body portion,
the connection terminals are provided in the connecting portion, and
the connecting portion is bent rearward at a boundary with the main portion and extends rearward from a lower end of the main portion.
