       8 . The component as claimed in  claim 1 , in which the film channel is formed from at least two layers of plastic.  
   
   
       9 . The component as claimed in,  claim 1 , wherein the film channel is attached in a thermally adhesive fashion and/or by bonding to the base body.  
   
   
       10 . The component as claimed in  claim 1 , in which the film channel is arranged on the base body by means of securing elements.  
   
   
       11 . The component as claimed in  claim 1 , in which the film channel is provided with a partition wall.  
   
   
       12 . The component as claimed in  claim 1 , in which the film channel exhibits a smaller cross section than the cross section of the base body and is arranged inside the base body in such a way that at least two chamber channels are formed.  
   
   
       13 . The component as claimed in  claim 1 , in which the base body is lined additionally on the internal wall, at least partially, with plastic applied by spraying.  
   
   
       14 . The component as claimed in, in which the film channel is provided with reinforcing elements on its outer side facing towards the base body.  
   
   
       15 . The component as claimed in  claim 1 , in which a plurality of film channels assembled inside one another are arranged in the base body.  
   
   
       16 . The component as claimed in  claim 1 , in which at least one film channel is executed as a deep-drawn half shell.  
   
   
       17 . A method for the production of a component as claimed in  claim 1 , having a base body exhibiting a cavity with at least an inner plastic covering, in conjunction with which a film channel made of plastic is introduced as a plastic covering in the cavity of the base body.  
   
   
       18 . The method as claimed in  claim 17 , in which the film channel is assembled in the base body itself or is pre-assembled in a separate forming tool and is then introduced into the base body.  
   
   
       19 . The method as claimed in  claim 17 , in which at least two layers of plastic are arranged one above the other and are compressed or welded at their lateral edges running in a longitudinal direction, in conjunction with which, following thermal pre-heating, the edges are then pushed together so as to cause the two layers of plastic to arch outwards in a mutually opposing direction.  
   
   
       20 . The method as claimed in  claim 17 , in which, in order to cause the layers of plastic to arch outwards, warm air is caused to flow between these until the layers of plastic arch outwards in a mutually opposing direction.  
   
   
       21 . The method as claimed in  claim 17 , in which air is led away via at least one recess in the base body or in the forming tool.  
   
   
       22 . The method as claimed in  claim 17 , in which a negative pressure is applied in order to cause arching outwards of the layers of plastic to take place outside the recess.  
   
   
       23 . The method as claimed in, in which the layers of plastic harden in the outward-arched state or adhere to the internal wall of the base body.  
   
   
       24 . The method as claimed in  claim 17 , in which the film channel is formed from at least two deep-drawn half shells, which are introduced into the base body.  
   
   
       25 . The method as claimed in  claim 24 , in which at least one additional layer of plastic is applied between the inserted, deep-drawn half shells.  
   
   
       26 . The method as claimed in claims  24 , in which at least two flat layers of plastic, in particular plastic films, are applied additionally between the inserted, deep-drawn half shells, between which at least one outward curve is produced by means of the inward flow of warm air.  
   
   
       27 . The method as claimed in  claim 17 , in which the film channel, in addition to the self-adhesion, is retained by means of a securing element on the base body.  
   
   
       28 . The method as claimed in  claim 17 , in which the base body is sprayed additionally, at least partially, with compact or foamed plastic.  
   
   
       29 . The method as claimed in  claim 17 , characterized in that a single-layer or multiple-layer plastic film is used as the layer of plastic.  
   
   
       30 . The use of a component as claimed in  claim 1  as an instrument panel carrier in a vehicle with a film channel, in particular with at least one air-guiding channel and/or a cable channel.  
   
   
       31 . The use of a component as claimed in  claim 1  as a structural component in a vehicle, in particular as a hollow structural element, as a longitudinal member, sill, center tunnel structure, front, longitudinal or transverse member, vertical structural element, A-, B-, C-, D-pillar, or roof structural element.  
   
   
       32 . Use of a component as claimed in  claim 1  as a structural component in a vehicle, in particular as a hollow structural component, through which air for a heating, cooling, air conditioning or ventilation device is conducted.
