Definitions

  • the invention relates to a draw-in bar for shaping the profile of upholstery materials covered on the outside by a cover material 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.
  • 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 the 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 prepared in this way is then drawn into and fixed in the upholstery material essentially transversely to the outer surface of the cover fabric lying on the upholstery 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 retaining strips formed on one of the two profile legs in practical use of the pull-in bar form an underside support of approximately the seam length by contacting a corresponding pad material surface opposite the blind seam for fixing the upholstery upholstery material drawn in via the sewing flag Seat part, e.g. of a car seat.
  • the upholstery material of these seat parts usually consists of foam, e.g. Polyurethane foam, steel wire rods or the like. 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 specified, which can be used in particular with seat parts made of foam 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 pull-in bar is provided with holding tabs arranged in its longitudinal direction at a distance from one another and formed by punch-outs incorporating the sewing-in flag, and the sew-on tab in the region of its free side edge opposite the receiving gap has a punch-out in the longitudinal direction of the pull-in bar bridging, in turn Plastic existing support rod.
  • the lateral retaining strips of the one, outer profile leg are shortened by the punched-outs to individual retaining 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, 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 formed thickened with the inclusion of the profile leg 3 towards a central ridge area.
  • the feed rod 1 is provided with punched-out punchings 8 which keep a distance from one another in its longitudinal direction and which include the previously welded-in sewing tab 5.
  • retaining tabs 9 are formed between the punched-out portions 8 and at the ends of the pull-in bar 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-outs 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 made in the cushion material, 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 that open out on the rear side 20 of the car seat part 17 and correspond to the shape of the surface of the holding tabs 9.
  • the shaped recesses 18 have an unequal depth, such that their base surfaces 21 have a thickness regardless of a varying upholstery material 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 shaped recesses 19 have, with the same cushioning material thickness over the blind seam course, the same depth among each other.
  • a push-through slot 22 aligned according to 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 sewn with the cover fabric 14 on the top of the seat part 17 state with their lateral retaining strips 6 and 7 to rest on the base 21 of the mold recesses 18 and 19 of the cushioning material 16.
  • the sew-on flag 5 then fills the respective push-through slot 22.
  • the holding tabs 9 in the shaped recesses 18 and 19 of the seat part 17, in the manner of an anchor provide a secure fixation for the strip-shaped area of the upper cover fabric 14 which is drawn in via the sewing tab 5 and forms the blind seam.
  • the torsion-free course of the blind seam which is cleanly contoured in the longitudinal direction of the seam This is ensured by the continuous support rod 11.
  • processing of the pull-in rod 1 is also possible without form recesses 18 or 19, in which case the retaining tabs 9 would rest directly on the rear side 20 of the upholstery material part.
