Air-distribution system for a structural unit in a vehicle passenger compartment

Abstract

An air-distribution system ( 20 ) for the distribution of air in a structural unit ( 30 ) in the passenger compartment of a vehicle, in particular in a vehicle seat ( 31 ). The system has at least one air-distribution layer ( 4 ), which is located on a base ( 6 ′), and at least one limiting mechanism ( 41 ′), which at least partially limits the air-distribution layer ( 4 ) laterally at at least one of its peripheral edges ( 53 ). The limiting means ( 41 ′) is designed as at least partially different from base such that it is not integral with the base.

An air-distribution system according to  claim 1 , wherein the base comprises a plurality of zones, which are delimited from one another by depressions, elevations or changes in height, and wherein at least one zone is delimited by the limiting mechanism or an additional limiting mechanism from at least one other zone.  
   
   
       7 . An air-distribution system according to  claim 2 , wherein the base comprises a plurality of zones, which are delimited from one another by depressions, elevations or changes in height, and wherein at least one zone is delimited by the limiting mechanism or an additional limiting mechanism from at least one other zone.  
   
   
       8 . An air-distribution system according to  claim 4 , wherein the base comprises a plurality of zones, which are delimited from one another by depressions, elevations or changes in height, and wherein at least one zone is delimited by the limiting mechanism or an additional limiting mechanism from at least one other zone.  
   
   
       9 . An air-distribution system according to  claim 2 , wherein at the accompanying layer there are located at least two sections of the air-distribution layer at least partially separated and at a distance from each other, the sections being substantially in the same plane to one another and along the accompanying layer, and wherein at least one limiting mechanism is located between two adjacent sections.  
   
   
       10 . An air-distribution system according to  claim 5 , wherein at the accompanying layer there are located at least two sections of the air-distribution layer at least partially separated and at a distance from each other, the sections being in the same plane to one another and along the accompanying layer, and wherein at least one limiting mechanism is located between two adjacent sections.  
   
   
       11 . An air-distribution system according to  claim 7 , wherein at the accompanying layer there are located at least two sections of the air-distribution layer at least partially separated and at a distance from each other, the sections being in the same plane to one another and along the accompanying layer, and wherein at least one limiting mechanism is located between two adjacent sections.  
   
   
       12 . An air-distribution system according to  claim 9  wherein the sections are fastened to the accompanying layer.  
   
   
       13 . An air-distribution system according to  claim 9  comprising at least one electrical conductor running from a first section to a second section of the air-distribution layer, the conductor being arranged in a non-straight route about its primary direction of run.  
   
   
       14 . An air-distribution system according to  claim 10  comprising at least one electrical conductor running from a first section to a second section of the air-distribution layer, the conductor being arranged in a non-straight route about its primary direction of run.  
   
   
       15 . An air-distribution system according to  claim 11  comprising at least one electrical conductor running from a first section to a second section of the air-distribution layer, the conductor being arranged in a non-straight route about its primary direction of run.
