View Patent ↗The invention relates to a motor vehicle, in which at least one microphone ( 8 ) is mounted in the headlining 94 ) of a passenger cell of the vehicle. The microphone is mounted in a location, which is concealed by a sun visor ( 6 ) that is pivotally mounted on the headlining ( 4 ) when said visor has been pivoted to lie against the headlining ( 4 ). At least the area ( 7 ) of the sun visor ( 6 ) that conceals the microphone is configured to conduct sound.
1. A motor vehicle having at least one microphone ( 8 ) fitted to a headliner ( 4 ) of a vehicle occupant cell of the vehicle and at least one sun visor ( 6 ) pivotally fitted to the headliner ( 4 ), wherein the microphone ( 8 ) is located at a point on the headliner ( 4 ) at which the microphone ( 8 ) is masked by the sun visor ( 6 ) in a position swung up against the headliner ( 4 ), and wherein the sun visor ( 6 ) is sound-permeable at least in its area masking the microphone ( 8 ), wherein the sun visor ( 6 ) has a plurality of air ducts ( 13 ) in its sound-permeable area ( 7 ), and wherein in the position in which the sun visor ( 6 ) is swung up against the headliner ( 4 ) the air ducts ( 13 ) are oriented basically parallel to a line ( 14 ) connecting the microphone to the head ( 15 ) of an occupant.
2. A motor vehicle having at least one microphone ( 8 ) fitted to a headliner ( 4 ) of a vehicle occupant cell of the vehicle and at least one sun visor ( 6 ) pivotally fitted to the headliner ( 4 ), wherein the microphone ( 8 ) is located at a point on the headliner ( 4 ) at which the microphone ( 8 ) is masked by the sun visor ( 6 ) in a position swung up against the headliner ( 4 ), and wherein the sun visor ( 6 ) is sound-permeable at least in its area masking the microphone ( 8 ), wherein the sun visor ( 6 ) has a plurality of air ducts ( 13 ) in its sound-permeable area ( 7 ), and wherein in the position in which the sun visor ( 6 ) is swung up against the headliner ( 4 ) the air ducts ( 13 ) are oriented basically parallel to a line ( 14 ) connecting the microphone to the head ( 15 ) of an occupant, and wherein said air ducts form a honeycomb structure.
3. The motor vehicle as claimed in claim 2 , wherein the length (l) of the air ducts ( 13 ) is greater than their width dimensions (b 1 , b 2 ).
4. The motor vehicle as claimed in claim 1 , wherein the sun visor ( 6 ) has at least one of at least one flat lattice structure and at least one perforated plate in its sound-permeable area ( 7 ).
5. The motor vehicle as claimed in claim 1 , wherein sun visor ( 6 ) has an opaque membrane ( 17 ) in its sound-permeable area ( 7 ).
6. The motor vehicle as claimed in claim 1 , wherein the sound-permeable area ( 7 ) is provided with a textile covering ( 10 ).
7. A sun visor for a motor vehicle having at least one microphone ( 8 ) fitted to a headliner ( 4 ) of a vehicle occupant cell of the vehicle, the sun visor ( 6 ) pivotally fitted to the headliner ( 4 ) masking the microphone ( 8 ) when in a position swung up against the headliner ( 4 ), wherein the sun visor ( 6 ) is sound-permeable at least in its area masking the microphone ( 8 ), wherein the sun visor ( 6 ) has a plurality of air ducts ( 13 ) in its sound-permeable area ( 7 ), and wherein in the position in which the sun visor ( 6 ) is swung up against the headliner ( 4 ) the air ducts ( 13 ) are oriented basically parallel to a line ( 14 ) connecting the microphone to the head ( 15 ) of an occupant.
