Patent attributes
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.
