Cushion for a vehicle seat

Abstract

A cushion has a cushion core, particularly made of a foam material, and an air-permeable and moisture-permeable covering layer that covers the core. To improve the climate comfort by ensuring good removal of moisture from the area between covering layer and cushion core, longitudinal and transverse grooves, spaced apart from one another, are formed in the surface of the cushion core covered by the covering layer. These grooves are open toward the covering layer and intersect one another. In addition, the cushion core is provided with channels which pass through the entire thickness of the core and which, at one end, open out at the points of intersection of the longitudinal and transverse grooves and, at the other end, open freely to the outside of the cushion core.

1 - 3 . (canceled)  
     
     
         4 . A cushion for a vehicle seat, comprising: 
 a cushion core made of a foam material,    an air-permeable and moisture-permeable covering layer by which the cushion core is lined, and    a network formed in the cushion core, the network comprising grooves spaced apart from one another, which are open toward the covering layer, and through which air is forced, and channels which pass through an entire core thickness of the cushion core and which, at one end, open into grooves and, at the other end, open out freely on an outer face of the cushion core directed away from said grooves,    wherein the grooves are intersecting longitudinal grooves and transverse grooves having intersection areas at which the channels open out,    wherein at least one shaft is provided in the cushion core, passes completely through the core thickness of the cushion core, opens out in at least one of the longitudinal grooves, the transverse grooves, or both the longitudinal and the transverse grooves, and is open on the outer face of the cushion core directed away from the longitudinal and transverse grooves, and    wherein a miniature fan, which sucks air in from an area surrounding the cushion, is arranged in the at least one shaft.    
     
     
         5 . The cushion as claimed in  claim 4 , wherein a mouth of the at least one shaft is positioned in an intersection area of one of the longitudinal grooves and one of the transverse grooves.  
     
     
         6 . The cushion as claimed in  claim 4 , wherein the covering layer has a support, made of reticulated foam, and an air-permeable lining stretching across the support.  
     
     
         7 . The cushion as claimed in  claim 5 , wherein the covering layer has a support, made of reticulated foam, and an air-permeable lining stretching across the support.
