Abstract

A vehicle exterior part includes a decorative body, a heater sheet, a connector pin. The decorative body includes a base material, and a transparent resin layer. The heater sheet includes a heat generating body, and an extending portion. A part of the heater wire in the extending portion is joined to the connector pin inside an outer periphery of the base material by a joining portion made of a conductive material. The outer periphery is formed with a window configured to join the heater wire to the connector pin by the joining portion in a state where a joining position is exposed to an outside of the outer periphery. The window is provided with a waterstop portion configured to restrict water from entering the joining position. The waterstop portion is formed by filling the window with a potting material.

First claim

What is claimed is:

1. A vehicle exterior part comprising:
a decorative body configured to decorate a vehicle;
a heater sheet including a heater wire configured to generate heat when energized, the heater wire being wired on an interior surface of a sheet base material; and
a connector pin configured to be coupled with a device for power supply, wherein:
the decorative body includes
a base material, and
a transparent resin layer disposed on an exterior side from the base material;

the heater sheet includes
a heat generating body disposed on an exterior side from the transparent resin layer, and
an extending portion extending from a peripheral edge of the heat generating body and disposed on an interior side from the transparent resin layer;

a part of the heater wire in the extending portion is joined to the connector pin inside an outer periphery of the base material by a joining portion made of a conductive material;
the outer periphery is formed with a window configured to join the heater wire to the connector pin by the joining portion in a state where a joining position is exposed to an outside of the outer periphery;
the window is provided with a waterstop portion configured to restrict water from entering the joining position; and
the waterstop portion is formed by filling the window with a potting material.

2. A vehicle exterior part comprising:
a decorative body configured to decorate a vehicle;
a heater sheet including a heater wire configured to generate heat when energized, the heater wire being wired on an interior surface of a sheet base material; and
a connector pin configured to be coupled with a device for power supply, wherein:
the decorative body includes
a base material, and
a transparent resin layer disposed on an exterior side from the base material;

the heater sheet includes
a heat generating body disposed on an exterior side from the transparent resin layer, and
an extending portion extending from a peripheral edge of the heat generating body and disposed on an interior side from the transparent resin layer;

a part of the heater wire in the extending portion is joined to the connector pin inside an outer periphery of the base material by a joining portion made of a conductive material;
the outer periphery is formed with a window configured to join the heater wire to the connector pin by the joining portion in a state where a joining position is exposed to an outside of the outer periphery;
the window is provided with a waterstop portion configured to restrict water from entering the joining position;
the waterstop portion includes a cover formed of a resin material; and
the cover is arranged with a gap from the joining position, and blocks the window in close contact with a peripheral edge of the window, the peripheral edge of the window being on an exterior side from the gap.

3. The vehicle exterior part according to claim 2 , wherein
the waterstop portion is welded to the peripheral edge of the window.
