Patent ID: 7418837

Claim:
A warpknitted spacer fabric ( 11 ) comprising two knitwear layers ( 12 , 13 ) which are positioned parallel relative to one another, and a plurality of pile yarns ( 14 ) connecting the two knitwear layers ( 12 , 13 ), wherein the pile yarns ( 14 ) which extend to and fro, wherein the two knitwear layers ( 12 , 13 ) comprise courses ( 22 , 23 ) generally extending in a direction of production, and weft threads ( 15 , 16 ) connected by knitting to the two knitwear layers ( 12 , 13 ), wherein the pile yarns ( 14 ) extend generally in the direction of production and are connected to the two knitwear layers ( 12 , 13 ), wherein at least one of the two knitwear layers ( 12 , 13 ) further comprises at least one weft thread ( 15 1 , 16 1 ), the at least one weft thread ( 15 1 , 16 1 ) having a lower tear strength then the other weft threads ( 15 , 16 ) and being worked in, thereby producing a substantially linear nominal separating region (T) and wherein, in the linear nominal separating region (T), at least one of the pile yarns ( 14 ) is left out, thereby providing a weakening of the substantially linear nominal separating region (T).
