Fastening system and associated anchoring part for a seat

Abstract

The invention relates to a fastening system for a seat for attaching upholstery to the foam cushion part of a seat having an anchoring part ( 10 ) which can be attached in anchoring elements ( 16 ) foamed into the cushion part and which for reliable attachment has two web bodies ( 24 ) which delimit between themselves a receiving space ( 24 ) for accommodating a connecting part ( 12 ) in which the upholstery can be attached.

1 . Fastening system for a seat, especially a vehicle or aircraft passenger seat, for attaching upholstery to the cushion foam part of the seat, having 
 at least one anchoring part ( 10 ) made as a profile strip, which anchoring part can be connected to the upholstery which for this purpose acts on at least one connecting part ( 12 ) which engages the assignable anchoring part ( 10 ) for producing a strong connection, and    at least one interlocking part ( 14 ) which can be at least partially foamed into the cushion foam part and which with two opposing interlocking elements ( 18 ) delimits a clamping channel ( 18 ), engaging which the anchoring part ( 10 ) with its anchoring elements ( 20 ) makes contact with the assignable interlocking elements ( 15 ), by fitting under them, characterized in that the anchoring part ( 10 ) has two web bodies ( 24 ) which delimit a receiving space ( 26 ) for holding the connecting part ( 14 ) and which protrude with a definable projection over the actual anchor body ( 28 ) of the anchoring part ( 10 ) and in the interlocked attached state project out of the clamping channel ( 18 ) with its interlocking elements ( 16 ) in the direction of the upholstery to be attached.    
   
   
       2 . The fastening system as claimed in  claim 1 , wherein the height of the projecting web bodies ( 24 ) is greater than or equal to the vertical distance between one of the web bodies ( 24 ) and the outermost end of the adjacent anchoring element ( 20 ).  
   
   
       3 . The fastening system as claimed in  claim 1 , wherein the height of the receiving space ( 20 ) between pairs of web bodies ( 24 ) is essentially equal to the vertical distance between the two outermost ends of one pair of anchoring elements ( 20 ).  
   
   
       4 . The fastening system as claimed in  claim 1 , wherein the width of the respective web body ( 24 ) is essentially twice the width of the receiving space ( 26 ).  
   
   
       5 . The fastening system as claimed in  claim 1 , wherein the anchor body ( 28 ) is designed as an arrowhead with anchoring elements ( 20 ) which point down to either side and which delimit an engagement space ( 30 ) between themselves and each respective assignable web body ( 24 ) for engaging the interlocking elements ( 16 ).  
   
   
       6 . The fastening system as claimed in  claim 5 , wherein the total width of two web bodies ( 24 ) with the receiving space ( 28 ) corresponds essentially to the width of the anchoring element ( 20 ) measured along a 45° line X which ends at the lowest point of the engagement space ( 30 ).  
   
   
       7 . The fastening system as claimed in  claim 1 , wherein the height of the clamping channel ( 18 ) between the pairs of interlocking elements ( 16 ) is slightly greater than the engagement height of the anchor body ( 28 ) in the clamping channel ( 18 ).  
   
   
       8 . The fastening system as claimed in  claim 1 , wherein the anchoring part ( 10 ) consists of an extrudable plastic, especially in the form of polyester, polystyrene, polycarbonate, acrylonitrile-polybutadiene-styrene graft polymer (ABS) or mixtures thereof.  
   
   
       9 . Anchoring part for a fastening system as claimed in  claim 1 , wherein it has two web bodies ( 24 ) which project vertically on the anchor body ( 28 ) of the anchoring part, which delimit a receiving space ( 26 ) for accommodating the connecting part ( 12 ), and which protrude with a definable projection over the anchor body ( 28 ), and wherein the connecting part ( 12 ) projects out of the receiving space ( 26 ) as a flexible attachment plate, a flat woven fabric or knit fabric.  
   
   
       10 . The anchoring part as claimed in  claim 9 , wherein the connecting part ( 12 ) consists of a plastic material, especially polyester, with a melting point which is higher than the melting point of the anchor body ( 28 ).
