Definitions

  • the invention relates to a piece of seating furniture with two side rails made of continuous cast aluminum according to the preamble of claim 1.
  • DE-A 3921970 discloses a piece of seating furniture that functions as a cantilever chair and has a plastic seat shell that is integrally connected to curved front legs. These front legs are made of metal with a circular, oval or rectangular cross section and are elastic. To the rear, the seating furniture is supported by struts, whereby the front legs and struts are fastened together on floor stand elements.
  • This well-known seating furniture is very bulky due to its fixed seat shell, the production is complex and the vibration behavior cannot be changed.
  • a similar piece of seating furniture is known from US Pat. No. 4,938,530: here the seat shell is suspended from a frame which forms a closed frame and is shaped in such a way that the user can pivot backwards.
  • Another piece of seating designed as a cantilever chair is known from DE-A 4033972: here, the seat and backrest are suspended from an arched front dome of a frame, the seat and backrest being articulated to one another in the rear area, and the seat to the front edge of the seat Frame is connected via a sliding guide.
  • DE-U 7342881.6 a further piece of seating furniture is known, in which both the seat and the backrest are made of plastic parts.
  • the steel tubes forming the frame have longitudinal slots in which correspondingly shaped edge parts of the backrest engage.
  • GB-PS 1281707 describes a piece of seating furniture which has two lateral profile rails which are connected by two cross members and have longitudinal slots in which the edge parts of a membrane forming the seat shell are held.
  • the well-known seating furniture is similar to the "Highframe" model from Alias. It cannot swing.
  • DE-A 3207352 a piece of seating furniture is known, the seat and backrest of which consist of a flexible membrane stretched in a metal frame. The membranes are fastened in the longitudinal grooves of the frame tubes by means of crimp metal.
  • the known furniture has a rather unusual design, in particular with regard to its stand frame consisting of a curved support tube. It is complex and cumbersome in terms of production and assembly.
  • the object of the invention to improve a piece of seating of the known type in such a way that it has specific oscillating properties of the seat shell, has fixed upholstery and an ergonomically designed seat and backrest membrane, and can be produced with as little effort as possible in terms of production technology.
  • This object is achieved by the features of claim 1 and the subclaims.
  • the essence of the invention is that a seat shell with ergonomic membrane and attached cushion is created from the two profile rails and the two cross members, and this shell is connected to the two cross members on the curved front dome of the stand frame made of extruded aluminum profiles. The rear dome of this stand frame can then be connected to either the rear or the front crossmember, in the latter case being articulated.
  • the seat shell is practically fixed locally, and the seating furniture is only weakly oscillatable.
  • the cross-section of the stand frame aluminum profiles creates frame flexibility in the longitudinal axis (direction of seat) of the seating furniture and good transverse stability, which means that the frame does not twist.
  • the seat shell primarily swings around an imaginary pivot point just below the seat level, with the rotatable rear dome following when the seat is loaded deflects at the top and thus gives the seating furniture a very specific vibration characteristic. Thanks to the use of extruded aluminum profiles, which do not have to be subsequently machined, the manufacturing effort is inexpensive, the weight of the seating furniture is low, and the upholstery can easily be attached using the piping.
  • the stand frame 13 has the stand part at the bottom, from the front end of which the front dome extends upwards in an arc, and first over the connecting flange 15 with the front cross member 14, and then is connected to the rear crossmember 2 via the connecting flange 7.
  • the rear dome of the stand frame 13 is rotatably mounted on the front cross member 14 in the bearing 17 of the connecting flange 16.
  • the stand frame 13 is covered with wooden armrest pads 18.
  • seating furniture that is basically the same as FIG.
  • FIGS. 1 and 2 that is to say with a skid standing frame, has a frame flexibility in the longitudinal axis and good transverse stability, which are determined by the cross sections of the aluminum profiles used.
  • 3 shows the structure of the multifunctional knot in the rear crossmember 2. This is connected to the stand mounting flange 7 by means of the screw 9, which rests in the screw head receptacle 8.
  • the profile rail 1 is screwed to the cross member 2 via the screw 6.
  • the membrane 3 is fixed in the groove 5 via the piping 4.
  • the cushion 10 has a piping 11 that acts Plastic part with a nose that engages in the groove 12.
  • the connecting flange 7 can have one or two arms.
  • FIG. 5 shows the connection of the rear dome of the stand frame 13 in the area of the front crossmember 14 in the oscillating model according to FIG. 1: Both the crossbar connection flange 15 and the stand frame connection flange 16 each have a bearing bore through which the bearing bolt 17 is guided. The flanges 15 and 16 are screwed to the rear or front dome of the stand frame 13, as can be seen, by means of two screws each.
  • 6 shows an alternative form of the profile rails 1 and the fastening of the membrane 3 and the chair cushion 10: In contrast to the embodiment shown in FIG.
  • the membrane groove 5 and the cushion groove 12 lie next to one another, and the membrane 3 is guided around the nose which closes off the groove 5 at the top.
  • This embodiment is largely equivalent to that shown in FIG. 3.
  • the fastening flag 19 consists of a textile fleece, which - as indicated by the two vertical lines in the drawing - is sewn to the cushion 10.
  • the keder part 11 is made of polypropylene, which has the advantage of being completely recyclable compared to PVC.
  • the pad 10 is preferably provided with horizontally extending pockets into which U-shaped brackets, for example made of spring steel, are inserted. Then the pad 10 turned over and fastened to the profile rail 1 by means of the clamps.
  • This embodiment not only ensures that the upholstery 10 is firmly seated, but also opens up the possibility of simply inserting or removing the upholstery 10 in the permanently mounted chair, for example for retrofitting or replacing the upholstery.
  • seating furniture according to the invention is not only inexpensive to manufacture, but can also be handled in a highly flexible manner during delivery and use.
  • the membrane 3 is designed in an ergonomically advantageous manner in the seat hump area less elastic than in the backrest area and in the thigh area.
