Embodiment Construction

[0037] now refer to figure 1 , which shows a body panel 2 , here a front bumper, which comprises a protective device for protecting at least one wave-emitting component 6 . The number of components can obviously vary.

[0038] This protection device, also called radome 4, protects the wave emitting member 6 in place on the front of the motor vehicle. In the example to be described below, the radar is placed behind the radome 4 (which is part of the body part 2 ), and electromagnetic waves transmitted or received by the radar pass through the radome 4 . Those skilled in the art understand that, depending on the function of the radar, the radar can be installed at another location of the vehicle, such as on the rear, side or roof.

[0039] Such as figure 2 As shown, the radome 4 is at least partially penetrated by the waves emitted by the wave emitting member 6 .

[0040] Therefore, it must be transparent to these waves. As stated above, the term "transparent to waves emit...

Abstract

The invention relates to a radome (4) for a motor vehicle, comprising: a main body (8) comprising at least one first region (5) which is transparent to waves emitted by at least one wave-emitting member (6) and at least partially transparent to visible light, a textile support (12) fixed to the main body (8) and covering the first region (5), the portion of the fabric support (12) covering the first area is transparent to the waves emitted by the wave emitting member, the fabric support (12) comprises, on its face in contact with the body (8), an optical fiber (10) woven on the fabric support (12) and arranged to diffuse visible light through the first area, and a deicer (14) of the radome (4) woven on the fabric support (12).

Description

technical field [0001] The present invention relates to motor vehicles equipped with wave-emitting means such as radar-type distance sensors, and more particularly to protective devices for protecting these sensors. Background technique [0002] More and more automobiles have body parts on which wave-emitting members are mounted. [0003] These wave-emitting means are, for example, one or more radars of the ACC type ("Adaptive Cruise Control" in English) which emit radio waves. [0004] Such wave-emitting components are shielded and protected, for example from bad weather, by protective devices commonly referred to as "radomes". In the remainder of the description, the term "radome" is used as a synonym for "protective device". [0005] These protections are intended to be penetrated by the waves emitted by the wave-emitting member, so they must be transparent to the latter. "Transparent to waves emitted by a wave emitting member" refers to the ability of a material penet...
