Insert part for foaming into foam cushion parts, preferably of vehicle or aircraft seats

Abstract

In an insert part for foaming into foam cushion parts, preferably of vehicle or aircraft seats, having at least one line-shaped fixing element ( 11 ) which, partially fixed in the foam material and partially kept clear of it, is used for the application of anchoring elements for securing the position of covering materials, the fixing element ( 11 ) consists of a plastic material ( 13, 17 ) which has ferromagnetic properties or which contains ferromagnetic portions, or the fixing element ( 11 ) has an inner core ( 15 ) with ferromagnetic properties which is at least partially surrounded by a plastic jacket ( 13 ).

1 . Insert part for foaming into foam cushion parts ( 1 ,  3 ), preferably of vehicle or aircraft seats, having at least one line-shaped fixing element ( 11 ) which, partially fixed in the foam material and partially kept clear of it, is used for the application of anchoring elements for securing the position of covering materials, characterized in that the fixing element ( 11 ) consists of a plastic material ( 13 ,  17 ) which has ferromagnetic properties or ferromagnetic portions, or that the fixing element ( 11 ) has an inner core ( 15 ) with ferromagnetic properties which is at least partially surrounded by a plastic jacket ( 13 ).  
   
   
       2 . The insert part as claimed in  claim 1 , wherein the fixing element ( 11 ) has the shape of a flexible plastic rod ( 17 ), preferably with a round cross sectional shape.  
   
   
       3 . The insert part as claimed in  claim 2 , wherein the fixing element ( 11 ) is a flexible rod ( 17 ) of a plastic which is provided with a ferromagnetic coating or which contains ferromagnetic components.  
   
   
       4 . The insert part as claimed in  claim 2 , wherein the fixing element ( 11 ) has a plastic tube ( 13 ) which forms an at least almost closed casing of the inner core ( 15 ) which has ferromagnetic properties.  
   
   
       5 . The insert part as claimed in  claim 4 , wherein the core is formed by a ferromagnetic wire ( 15 ).  
   
   
       6 . The insert part as claimed in  claim 4 , wherein the core is formed by a substance which contains ferromagnetic components and which is located within the plastic tube.  
   
   
       7 . The insert part as claimed in  claim 2 , wherein the fixing element ( 11 ) for the application of clamp-like anchoring elements extending behind it has a sequence of alternating longitudinal sections ( 7 ) which are kept clear of foam material and which are separated from each other by longitudinal sections ( 9 ) which are fixed in the foam material.  
   
   
       8 . The insert part as claimed in  claim 7 , wherein the longitudinal sections ( 7  and  9 ) of the fixing element ( 11 ) which are fixed in the foam material and which are kept clear of the foam material each have approximately the same length.  
   
   
       9 . The insert part as claimed in  claim 7 , wherein the fixing element ( 11 ) in the longitudinal sections ( 7 ) which are kept clear of foam material is provided with a foam-repellent coating.  
   
   
       10 . The insert part as claimed in  claim 1 , wherein the plastic jacket ( 13 ) is structured to increase its active surface.
