Series of components for a vehicle seat

Abstract

A series of components is provided for a vehicle seat of a motor vehicle. Each vehicle seat has a cushion core with ventilation ducts running along and inside a seat surface and/or backrest surface. Ventilation channels are arranged essentially transversely to the ventilation ducts, penetrate the entire thickness of the cushion core and extend from the ventilation ducts as far as a rear wall facing away from the seat surface and/or backrest surface. For a passively ventilated vehicle seat, the ventilation channels are connected in a flow-permeable manner to the surroundings via an opening in the ear wall, whereas, in an actively ventilated vehicle seat, at least one fan is provided and at least one ventilation channel is closed.

         13 . Components for a motor vehicle seat having a cushion core, comprising: 
 ventilation ducts running along and inside at least one of a seat surface and backrest surface, and    ventilation channels arranged essentially transversely to the ventilation ducts, penetrate an overall thickness of the cushion core and extend from the ventilation ducts up to a rear wall facing away from at least one of the seat surface and backrest surface, wherein    for passively ventilated vehicle seat, the ventilation channels are flow-permeably connected to the surroundings via an opening in the rear wall, and for an actively ventilated vehicle seat, at least one fan is provided and at least one ventilation channel is close.    
     
     
         14 . The components as claimed in  claim 13 , wherein the cushion core has, on the rear wall, a flow-impermeable layer in the passively ventilated vehicle seat and is pierced or removed in a mouth region of at least one of the ventilation channels.  
     
     
         15 . The components as claimed in  claim 13 , wherein the cushion core has, on the rear wall, a respective opening in a mouth region of the ventilation channels in the actively ventilated vehicle seat, at least one of the ventilation channels is closed.  
     
     
         16 . The components as claimed in  claim 14 , wherein the flow-impermeable layer is at least one of a plastic layer and a felt layer.  
     
     
         17 . The components as claimed in  claim 16 , wherein the plastic layer is a film.  
     
     
         18 . The components as claimed in  claim 13 , wherein the ventilation ducts are configured as a duct grid and intersect in a flow-connected manner.  
     
     
         19 . The components as claimed in  claim 13 , wherein an arrangement of at least one of the ventilation ducts and ventilation channels is adapted to at least one of a body pressure distribution and body contact points.  
     
     
         20 . The components as claimed in  claim 13 , wherein at least one of the ventilation ducts and ventilation channels are arranged essentially regularly.  
     
     
         21 . The components as claimed in  claim 13 , wherein the actively ventilated vehicle seat has at least one inflow channel through which ambient air passes into the vehicle seat, at least one outflow channel through which air passes from the vehicle seat into the surroundings, and closed ventilation channels arranged between the at least one inflow channel and the at least one outflow channel  
     
     
         22 . The components as claimed in  claim 13 , wherein a controllable ventilation channel closure is operatively interacted with the at least one fan to provide active or passive ventilation of the vehicle seat.  
     
     
         23 . An actively ventilated motor vehicle seat having a cushion core, comprising ventilation ducts running along and inside at least one of a seat surface and backrest surface, ventilation channels arranged essentially transversely to the ventilation channels, so as to penetrate an overall thickness of the cushion core and extend from the ventilation ducts up to at least one of a rear wall facing away from the seat surface and backrest surface, and at least one fan, wherein at least one ventilation channel is closed.  
     
     
         24 . The actively ventilated vehicle seat as claimed in  claim 23 , wherein the cushion core has, on the rear wall, a flow-impermeable layer in the passively ventilated vehicle seat and is pierced or removed in a mouth region of at least one of the ventilation channels.  
     
     
         25 . The actively ventilated vehicle seat as claimed in  claim 23 , wherein the cushion core has, on the rear wall, a respective opening in a mouth region of the ventilation channels in the actively ventilated vehicle seat, at least one of the ventilation channels is closed.  
     
     
         26 . The actively ventilated vehicle seat as claimed in  claim 23 , wherein the ventilation ducts are configured as a duct grid and intersect in a flow-connected manner.  
     
     
         27 . The actively ventilated vehicle seat as claimed in  claim 23 , wherein an arrangement of at least one of the ventilation ducts and ventilation channels is adapted to at least one of a body pressure distribution and body contact points.  
     
     
         28 . The actively ventilated vehicle seat as claimed in  claim 23 , wherein at least one of the ventilation ducts and ventilation channels are arranged essentially regularly.  
     
     
         29 . The actively ventilated vehicle seat as claimed in  claim 23 , wherein the actively ventilated vehicle seat has at least one inflow channel through which ambient air passes into the vehicle seat, at least one outflow channel through which air passes from the vehicle seat into the surroundings, and closed ventilation channels arranged between the at least one inflow channel and the at least one outflow channel
