Vehicle seat

Abstract

The vehicle seat has a supporting element in the form of a seat and/or back section with a padded core 2 in at least one piece for supporting a seat user, with a cover 9 that at least partially conceals the padded core 2 , and with an anchoring channel on which the surface of the supporting element features an elongated depression 17 . Provision is made for an anchoring device 21, 22, 24 which draws in the cover 9 at least indirectly along the anchoring channel in the direction of the seat core 2 into the supporting element. Between the cover 9 and the seat core 2 provision is made for a ventilation layer 55 through which air can flow that is curved to the contour of the depression 17 of the anchoring channel, at least partially following it, such that the ventilation layer 55 in the area of the anchoring channel essentially retains its layer thickness (d) in spite of the depression 17 in the surface.

1 . A vehicle seat comprising: 
 a supporting element in the form of a seat or back section;    a padded core in at least one piece for supporting a seat user;    a cover that at least partially conceals the padded core;    an anchoring channel in the form of an elongated depression on a surface of the supporting element, with an anchoring device which draws in the cover at least indirectly along the anchoring channel in the direction of the seat core into the supporting element; and    a ventilation layer which is placed between the cover and the seat core and through which air can flow,    wherein the ventilation layer is curved to the contour of the depression of the anchoring channel, at least partially following the anchoring channel, and the ventilation layer in the area of the anchoring channel essentially retains its layer thickness (d) when stress is exerted on the ventilation layer by a seat user.    
   
   
       2 . The seat according to  claim 1 , wherein the hollow space of the ventilation device through which air can flow has an overall height of a maximum of 20 mm vertical to the surface of the supporting element turned towards the seat user.  
   
   
       3 . The seat according to  claim 2 , wherein the hollow space has an overall height of a maximum of 10 mm.  
   
   
       4 . The seat according to  claim 2 , wherein the ventilation layer has an overall height of a maximum of 20 mm.  
   
   
       5 . The seat according to  claim 1 , wherein the ventilation layer is at least partially concealed towards the user by an air-permeable first surface layer including a single or multi-layered cover, a layer-like carrier or a surface heating element placed between the cover and the ventilation layer.  
   
   
       6 . The seat according to  claim 5 , wherein the ventilation layer is at leat partially concealed towards the the padded core by a non-air-permeable second surface layer.  
   
   
       7 . The seat according to  claim 6 , wherein the ventilation layer includes one or more spacers which separate the cover and the padded core from one another and which are placed on the first surface layer, the carrier, the second surface layer or the padded core.  
   
   
       8 . The seat according to  claim 5 , wherein at least one spacer is at least pointed in shape, by means of one or several projections of a layer adjoining the ventilation layer, by means of strips of fabric in sections and spaced apart from one another in the ventilation layer, by means of tubular elements which have an approximately rectangular cross section and walls with air flow openings, or by means of helices or spirals made of flat material, which have helix threads spaced apart from one another to facilitate the passage of air at right angles to the longitudinal axis of the helix, and which are flattened out in order to arrange the helices with their flattened-out area on the carrier.  
   
   
       9 . The seat according to  claim 1 , wherein the padded core in the area of the anchoring channel has an elongated depression that the depression is covered over by the cover or the first surface layer, that provision is also made in the area of the anchoring channel for the ventilation layer at least partially between cover or surface layer and the padded core, that the cover or the surface layer is drawn from the anchoring device towards the bottom of the depression, and that at the bottom of the recess or on its lateral areas, at least one spacer is placed.  
   
   
       10 . The seat according to  claim 9 , wherein between the bottom of the depression, the cover or the surface layer and the anchoring device a hollow space remains, the overall height of which corresponds at least to the height of the ventilation layer through which air can flow.  
   
   
       11 . The seat according to claim,  10  wherein at least one spacer is elongated, that air can flow through it lengthways and at right angles to its longitudinal axis or that it is placed lengthways to the depression.  
   
   
       12 . The seat according to  claim 1  further comprising an air-conditioning device.
