Textile lever device

Abstract

Textile lever device including an airbag (one-piece-woven or OPW airbag) having single-layer and multi-layer areas, the airbag being woven in one piece, with inflatable chambers lying next to each other substantially in a main direction of pull, specifically a main chamber and at least one first side chamber connected to the main chamber via a single-layer area, wherein the chambers have an upper fabric layer and a lower fabric layer, and wherein pull threads running in the main direction of pull are firmly anchored in the upper or lower fabric layer of the first side chamber, are moveably looped through the single-layer area, and in the main chamber are moveably looped on alternately in the upper fabric layer and lower fabric layer at predefined distances oriented to the main direction of pull, and are anchored to at least one point in the main chamber.

What is claimed is: 
     
         1 . A textile lever device comprising an airbag, said airbag being woven in one piece (one-piece-woven or OPW airbag) having single-layer and multi-layer portions, with inflatable chambers lying next to each other substantially in a main direction of pull, specifically a main chamber and at least one first side chamber connected to the main chamber via a single-layer portion, wherein
 the chambers have an upper fabric layer and a lower fabric layer, and wherein   pull threads running in the main direction of pull:
 a) are firmly anchored in the upper or lower fabric layer of the first side chamber, 
 b) are movably looped through the single-layer portion, 
 c) in the main chamber are moveably looped in alternately in the upper fabric layer and the lower fabric layer; at predefined distances oriented to the main direction of pull, and 
 d) are anchored to at least one point in the main chamber. 
   
     
     
         2 . The textile lever device as set forth in  claim 1 , further comprising at least one second side chamber connected via a single layer portion to the main chamber opposite the first side chamber in relation to the main chamber. 
     
     
         3 . The textile lever device as set forth in  claim 1 , further comprising a third side chamber connected via a single layer portion to the first side chamber, the pull threads running in the main direction of pull being looped shiftingly through each upstream side chamber alternatingly in the upper fabric layer and the lower fabric layer. 
     
     
         4 . The textile lever device as set forth in  claim 2 , comprising a fourth side chamber connected via a single layer portion to the second side chamber, the pull threads running in the main pull direction being looped shiftingly through each upstream side chamber alternatingly in the upper fabric layer and the lower fabric layer. 
     
     
         5 . The textile lever device as set forth in  claim 1 , wherein the main chamber and/or the side chamber(s) comprise so-called tether devices connecting the upper fabric layer and the lower fabric layer and their tether devices restricting the distance from each other. 
     
     
         6 . The textile lever device as set forth in  claim 1 , any of the preceding wherein the outer surfaces of the device comprise at least portionally a friction enhancing coating. 
     
     
         7 . The textile lever device as set forth in  claim 1 , any of the preceding wherein the outer surfaces of the device are laminated at least portionally.
