Abstract

The invention relates to a method for integrating fasteners into a knitted seat cover for attachment to a seat-cover support by means of a flatbed knitting machine, whereby fastening areas are provided on the side of the seat cover facing the support for attachment to said support while the seat cover is being knitted and said fastening areas interact with additional fastening areas on the support of the seat cover. According to the invention, the fastening areas on the seat cover are embodied as flat velcro structures (hook and loop closures) while the loop areas of the velcro structures are knitted and integrated into the seat cover as flat surfaces during the manufacture thereof. Hook areas of the velcro structure provided on the seat cover are formed by knitting and integrating a hard or hardenable monofilament in the form of loops that protrude towards the support and are subsequently cut or cut during knock-over/after knock-over of the stitches from the needles of the flatbed knitting machine. This enables said fasteners to be integrated in such a way that it is possible to produce the seat cover without any substantial increase in machine running times.

knitting the seat cover by means of a flat-bed knitting machine and, during knitting of the seat cover, providing the hook portion of the fastening structure by knitting in a hard or hardenable monofilament in loops projecting out toward the support and cutting the loops open.

8. The process of claim 7, including casting the loops of monofilament off from the needles of the flat-bed knitting machine and cutting the loops during the casting off.

9. The process of claim 7, including casting the loops of monofilament off from the needles of the flat-bed knitting machine and cutting the loops after the casting off.

10. The process of claim 7, comprising cutting the loops of monofilament at a predetermined angle.

11. A knitted seat cover for fastening to a seat cover support provided with a first portion of a fastener including first and second complementary portions, wherein the second portion of the fastener is provided on a side of the seat cover facing the seat cover support and is formed by integrated adhesive threads whose adhesive characteristics are activated at elevated temperatures.

12. The seat cover of claim 11, wherein the second portion of the fastener includes thermal shrink threads knitted in or incorporated into the seat cover.

13. The seat cover of claim 12, wherein the shrink threads are incorporated into the knitted fabric as warp threads.

14. The seat cover of claim 12, wherein the shrink threads are incorporated into the knitted fabric as weft threads.

15. The seat cover of claim 12, wherein the seat cover has an outer side facing away from the seat cover support and the shrink threads are disposed in three-dimensionally contoured areas in which the outer side of the cover is convexly curved.

16. The seat cover of claim 11, wherein the adhesive threads are incorporated into the knitted fabric as warp threads.

17. The seat cover of claim 11, wherein the adhesive threads are incorporated into the knitted fabric as weft threads.
