Method for production of a fixing piece

Abstract

The invention relates to a method for the production of a fixing piece (12,36), which particularly serves for the fixing of covering material to cushion pieces for vehicle seats, whereby 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), whereby 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 invention, the known welding and glued connecting applications can be further improved such that said production method can be rapidly carried out with low production costs and without additional materials and a strong connection can be achieved, conforming to more stringent environmental aspects, whereby the 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.
