The cover member encloses the structural member, and each are fastened to the other in a fixing section. The fixing section is formed by the cover member or the structural member, and is protected by a protective layer applied to the structural member and extending into or overlapping the fixing section. Alternatively, the fixing section is formed by the cover member or a housing, and is covered by the housing or the housing extends into or overlaps the fixing section. The housing forms an opening for the radar waves (λr). ## Claims ### Claim 1 A radome for a radar device for a vehicle, the radome comprising: a cover member made of a radar-transparent resin; a structural member made of a radar-transparent resin, wherein the structural member comprises an optical lens, and wherein a gap is defined between the cover member and the optical lens; the cover member enclosing the structural member; the cover member and the structural member being fastened to each other in a fixing section; at least one of: the fixing section being formed by the cover member or the structural member, the fixing section being protected by a protective layer, the protective layer being applied to the structural member and extending into or overlapping the fixing section, or the fixing section being formed by the cover member or a housing, the fixing section being covered by the housing or the housing extending into or overlapping the fixing section, the housing forming an opening for radar waves (λr). ### Claim 2 (depends on 1) The radome according to claim 1, wherein the cover member is made of a light transparent resin, the optical lens is made of a light transparent resin, and the radome further comprises a light source for illuminating the radome. ### Claim 3 (depends on 1) The radome according to claim 1, wherein the optical lens includes a diffusive material that optimizes light performance. ### Claim 4 (depends on 2) The radome according to claim 2, wherein the light source is fastened to at least one of: the cover member or the structural member or the housing. ### Claim 5 (depends on 1) The radome according to claim 1, wherein at least one of: the protective layer is radar transparent, or radar transparent and reflective to light, or a protective layer is applied to the structural member and is at least one of radar transparent, or radar transparent and reflective to light. ### Claim 6 (depends on 5) The radome according to claim 5, wherein the protective layer is opaque to light. ### Claim 7 (depends on 5) The radome according to claim 5, wherein the protective layer is reflective and comprises at least one of white PC/PMMA, white lacquer, white tampon or pad print, white screen print or metallized or a red pigment. ### Claim 8 (depends on 5) The radome according to claim 5, wherein the protective layer is a reflective foil. ### Claim 9 (depends on 1) The radome according to claim 1, wherein the cover member includes an outer surface and an inner surface, and a decorative layer is applied to the inner surface and/or to the outer surface. ### Claim 10 (depends on 9) The radome according to claim 9, wherein the decorative layer has the same composition as the protective layer. ### Claim 11 (depends on 9) The radome according to claim 9, wherein a radar-transparent lacquer is applied to the outer surface. ### Claim 12 (depends on 1) The radome according to claim 1, further comprising a heating unit for heating the radome. ### Claim 13 (depends on 1) A radar device for a vehicle, the radar device comprising: a radome according to claim 1; and a radar source for providing radar waves (λr). ### Claim 14 (depends on 13) A cladding component for a vehicle, the cladding component comprising: a radar device according to claim 13. ### Claim 15 (depends on 1) The radome according to claim 1, wherein the radome further comprises a light source for illuminating the radome, wherein the optical lens is configured to direct light from the light source toward the cover member. ### Claim 16 (depends on 15) The radome according to claim 15, wherein the optical lens has a first surface that faces the cover member and a second surface opposite the first surface, wherein the protective layer is applied to the second surface of the optical lens, wherein the protective layer is configured to reflect the light from the light source toward the cover member.
