Definitions

  • the invention relates to a draw-in bar for shaping the profile of upholstery materials covered with a cover fabric on the outside in upholstered furniture and the like their base are connected to each other by a narrow connecting web and define a receiving gap starting from the latter, which defines the sewing flag with one of its side edges, one of the two profile legs being provided at both ends with integrally molded lateral retaining strips.
  • EP-A-403 815 discloses a known feed rod of this type according to the preamble of claim 1.
  • Such pull-in rods are used in upholstered furniture, but also in other upholstered seat parts, such as, in particular, car seats including their backrests, to bring upholstery material attached to a suitable base into the desired shape that is appropriate for the seat or body.
  • the cover fabric is sewn onto the sew-on tab of the profile body, and the feed rod thus prepared is then drawn into the cushion material and fixed essentially transversely to the outer surface of the cover fabric lying on the cushion material, whereby a seam-like so-called blind stitching or blind seam with corresponding profile curvatures on both sides of the Blind seam is generated.
  • the lateral holding strips formed on one of the two profile legs in practical use of the pull-in bar form a support on the underside of approximately seam length by abutment on a corresponding pad material surface opposite the blind seam to fix the thread that is drawn in via the sewing tab top fabric of the upholstered seat part, e.g. of a car seat.
  • the upholstery material of these seat parts usually consists of foam, e.g. Polyurethane foam, where steel wire rods or similar metal parts are often foamed into the foam material for sufficient strength and shape retention of the seat part.
  • the invention has for its object to provide a feed rod of the type mentioned, which can be used in particular in the case of foam seat parts without foamed metal reinforcement in order to produce continuous, cleanly contoured blind stitching or blind seams in the upholstery material without this being undesirable Way is weakened.
  • the draw-in bar is provided with holding tabs which are arranged at a distance from one another in its longitudinal direction and are formed by punch-outs incorporating the sew-on flag, and the sew-on tab in the region of its free side edge opposite the receiving gap has a cut-out in the longitudinal direction of the draw-in bar bridging, in turn Plastic existing support rod.
  • the lateral holding strips are shortened by the punched-out holes in the longitudinal direction of the draw-in rod to individual holding tabs which can be pulled through appropriately contoured individual shape recesses in the upholstery material, in particular foam, without any significant weakening of the foam material occurring through these individual shape recesses.
  • the profile body then lies in practical use only in the area of these recesses with the retaining tabs on the back or underside of the upholstery material. Any bulges or deformations of the top blind seam, which could be caused by the areas not supported on the back or underside, which are defined by the punched-out sections of the profile body, are counteracted by the support rod which runs in the longitudinal direction of the sewing flag and bridges the punched-out section. Therefore, with the help of the pull-in bar according to the invention, cleanly contoured blind seams can be produced in the usual way, in particular in the case of seat parts made of foam without internal reinforcement.
  • the pull-in bar according to the invention can also be used with other upholstery or spring bases, for example those made of fabric.
  • the pull-in bar shown in FIG. 1 with a section, designated as a whole by 1 is based on one piece extruded profile body made of, for example, polypropylene with a two-legged cross-sectional profile, the two profile legs 2 and 3 of which are connected to one another at their base by a narrow connecting web 4. Starting from the connecting web 4, the two profile legs 2 and 3 delimit a receiving gap which receives a separately produced sewing flag 5 and in which the sewing flag 5 is fixed by welding.
  • the sew-on flag 5 consists of a fleece, mesh fabric or the like. Textile that can be easily welded to the feed rod 1 and fills the receiving gap completely with one of its side edges.
  • the profile leg 3 is provided at both ends with integrally molded lateral retaining strips 6 and 7, the connecting web 4 forming the transition between the latter and the lateral retaining strip 6 in the region of the profile leg 3.
  • the holding strips 6 and 7 are designed to be thicker with inclusion of the profile leg 3 toward a central ridge area.
  • the draw-in rod 1 is provided with punched-out punchings 8 which keep a distance from one another in its longitudinal direction and which also include the previously welded-on sewing tab 5.
  • retaining tabs 9 are formed between the punched-out portions 8 and at the ends of the pull-in rod 1, each of which, as retaining parts, comprises the profile leg 3 with the laterally molded retaining strips 6 and 7.
  • the sewing flag 5 carries a support rod 11 which extends in its longitudinal direction and bridges the punched-out portions 8.
  • the support rod 11 is fixed adjacent to the mutually aligned base lines 12 of the punched holes 8 and at a parallel distance from the free side edge 10 of the sewing flag 5 on one of its two surface sides.
  • the support rod 11 is fixed on the surface side of the sewing flag 5 facing the holding leg 7 of the holding tabs 9.
  • the support rod 11 has a full profile, in particular a rounded rectangular profile, and in this case has a flat side which bears against the sewing flag 5 and serves as a connecting surface.
  • the support rod 11 in turn consists of a separately produced extruded profile body, which is advantageously welded to the sewing flag near its free edge 10.
  • the retaining tabs 9 or the extruded profile body forming them with the aid of the punchings 8, the sewing tab 5 and the support rod 11 are all made of the same or a similar, easily weldable plastic. This ensures good mutual welding of these three parts of the feed rod 1.
  • FIG. 2 shows the connection of the cover fabric 14 with the sewing flag 5 by means of a sewing seam 15 which is directly adjacent to the support rod 11. In this area, the cover fabric 14 is drawn inwards into the cushion material 16 and forms a profile-forming blind stitching or blind seam.
  • FIG. 3 illustrates an example of an application of a cushion material part in the form of a car seat part 17, wherein shaped recesses 18 and 19 are introduced into the cushion material 16, which is usually made of foam, in a longitudinal row arrangement in accordance with the desired blind seam course.
  • the shaped recesses 18 and 19 are in the form of blind holes with a cross-sectional shape which open out on the rear side 20 of the car seat part 17 and correspond to the shape of the surface of the holding flaps 9.
  • the shaped recesses 18 have an unequal depth, such that their base surfaces 21 have a shape regardless of a varying upholstery material thickness the blind seam course, the same distance from the top of the car seat part 17 with the cover fabric 14, which corresponds to the length of the sewing flag 5 between the seam 15 and the retaining tabs 9.
  • the shape recesses 19 have, with the same cushioning material thickness over the course of the blind seam, among themselves the same depth.
  • a push-through slot 22 aligned in accordance with the intended blind seam course, through which the holding tabs 9 of the pull-in bar 1, with the holding strip 6 attached to the sewing-on tab 5, are extended, in order to be processed by the sewing-on tab 5 folded and with the cover fabric 14 sewn on the top of the seat part 17 state with their lateral retaining strips 6 and 7 to rest against the base 21 of the mold recesses 18 and 19 of the cushioning material 16.
  • the sew-on flag 5 then fills the respective through slot 22.
  • processing of the pull-in rod 1 without form recesses 18 or 19 is also possible, in which case the retaining tabs 9 would rest directly on the rear side 20 of the upholstery material part.
