摘要： A millimeter wave transmissive decoration is arranged forward of a millimeter wave radar device in an emission direction of millimeter waves. The millimeter wave transmissive decoration includes a layer structure including layers stacked in the emission direction. The layers include a decorative layer and a plastic layer. At least part of the decorative layer is made of a white plastic layer. The plastic layer is in contact with the white plastic layer. The white plastic layer is made of a polycarbonate plastic containing particles of titanium oxide having a rutile crystal structure. A thickness in the emission direction of the white plastic layer is less than or equal to 2.0 mm. A permittivity of the white plastic layer is less than or equal to 3.1. An L value in a Lab color space of the white plastic layer is greater than or equal to 80.

摘要： A vehicle exterior part includes a decoration body including a layer structure formed by laminating layers in a front-rear direction, and includes a heater sheet including a transparent sheet base and a heater wire. The decoration body includes a transparent resin layer at a frontmost part of the decoration body and a decorative layer located rearward from the transparent resin layer. The transparent resin layer includes a general portion and an outer edge. A front surface of the general portion includes a general surface. The outer edge includes a bend surface that is curved or angular to a larger extent than the general surface. The sheet base includes a body located in front of the transparent resin layer and an extension extending from a periphery of the body. The body and a portion of the heater wire arranged on the body are located in front of only the general surface.

摘要： A vehicle exterior component includes a decoration body and a heater wire that includes a first heater wire portion arranged inside a passage region for millimeter waves in an up-down direction and a second heater wire portion arranged outside the passage region and extending horizontally on at least one of upper or lower sides of the first heater wire portion. The first heater wire portion includes linear portions horizontally spaced apart from each other and extending in the up-down direction and fold-back portions each connecting ends of adjacent ones of the linear portions such that all the linear portions are connected into one. The fold-back portions include a fold-back portion adjacent to the second heater wire portion. An interval of the narrowest part between the second heater wire portion and the fold-back portion adjacent to the second heater wire portions is set to between 2 mm and 7 mm, inclusive.

摘要： A vehicle exterior component includes a decorative main body and a heater sheet that includes a heating wire and a sheet base made of a plastic. The heating wire is routed on the back surface of the sheet base. The heater sheet includes a heating main body that is arranged to be closer to a front side than the decorative main body, and an extending portion that is bent along the outer circumference of the decorative main body to be arranged at a position closer to a back side than a front surface of the decorative main body. The extending portion includes a bent portion along the outer circumference. The wire length of the heating wire in the bent portion is set to a length that allows the heating wire to change shape to adapt to expansions and contractions of the sheet base in the bent portion.

摘要： A garnish includes a heating element, a base member, and a circuit board. The heating element is configured by stacking first and second sheet materials and interposing a heater wire in between. The circuit board includes a power source line and is fixed to a back surface of the base member. The heating element includes a main body portion and an extending portion. The extending portion includes a power source connection portion for connecting the heater wire to the power source line and extends to the back surface of the base member. The main body portion of the heating element is fixed to a laying surface of the base member by fixing the second sheet material to the base member. The heater wire is exposed in the power source connection portion without stacking the second sheet material on the first sheet material.

摘要： 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.

摘要： A vehicle decorative component includes a decorative main body and a heating wire. The vehicle decorative component includes a design surface on the front surface in the transmission direction of electromagnetic waves. The area from the design surface to a position behind and separated from the design surface in the transmission direction is constituted by a transparent member having a transparency to electromagnetic waves. The heating wire is disposed on the rear surface of the transparent member in the transmission direction. The heating wire includes a metal lead, which generates heat when energized, and a coating portion made of plastic. The coating portion coats the lead and constitutes the outer circumferential portion of the heating wire. At least the outer circumferential portion of the coating portion is constituted by a transparent coating portion, which is made of a transparent plastic.
