Method for production of a fixing piece
First Claim
1. A method of producing a fixing piece to fasten cover materials on upholstery components in seats, comprising the steps of:
- producing a profile component with a mounting opening therein predominantly from a first plastic material with a first melting point range;
producing a sew-on tag separately from the profile component and predominantly of a second plastic material with a second melting point range, said first and second melting point ranges being different;
locating a portion of the sew-on tag in the mounting opening of the profile component;
subjecting the profile component and the sew-on tag to thermal action so that one of the first and second plastic materials remains substantially stable while the other of the first and second plastic materials penetrates recesses in the one of the first and second plastic material; and
cooling the plastic materials of the profile component and the sew-on tag such that the other of the first and second plastic materials solidifies in the recesses to bond the profile component and the sew-on tag.

Abstract
A method for the production of a fixing piece (12, 36) serves for fixing of covering material to cushion pieces for vehicle seats. A profile body (12) is connected to a separately produced sewn tag (36) which at least partly engages in a housing opening (34) in the profile body (12). The profile body (12) and the sewn tag (36), at least in the common jointing positions thereof, are predominantly made of plastic materials. According to the present invention, the known welding and glued connecting applications can be further improved such that the production method can be rapidly carried out with low production costs and without additional materials. A strong connection can be achieved, conforming to more stringent environmental aspects. Fusion temperatures of the plastic materials employed for the profile body (12) and the sewn tag (36) are selected with a difference such that one plastic material remains essentially stable in form under thermal effect during generation of the joint, and the other plastic material flows into recesses (38) formed in the first plastic material, and is solidified in the recesses (38) on cooling.
