Definitions

  • the invention relates to a seat cover for seating furniture of all kinds, which makes self-ventilation possible without a blower unit, is transportable and easy to clean, and can be easily adapted.
  • the aim of the invention is to create a seat cover which generates ventilation of the seat surface in the simplest possible way.
  • the object of the invention is to create a seat cover for seating furniture of all types, with rear ventilation of the seat cover without a fan unit and thus constant ventilation of the seat surface.
  • a seat cover for seating furniture of all kinds was created, which is made in particular from spiral springs of known design.
  • a seat pad is woven from individual spiral springs, which are twisted into one another. After a respective spiral spring has been screwed into the previous spiral spring, a hook is carried out at the respective end of a spiral spring so that it does not twist out.
  • the spiral springs connected to one another are thus secured against unscrewing.
  • spiral springs are screwed in offset by 180 degrees and connected to the respective hook at the end.
  • the hook shape is designed in particular so that the end of the spiral spring is bent into the spiral spring. This creates a hook for anchoring the respective spiral spring to one another.
  • the interlocking of the respective spiral springs with one another has the purpose of not getting injured or getting caught.
  • the inventive solution consists in the fact that the twisting of spiral springs into one another creates a surface in which the body does not touch the seat surface of the chair when sitting. This non-contact ensures constant ventilation of the seat surface through the seat support and the hollow space created from the spiral spring mesh.
  • the material of the spiral spring is advantageously made of hardened and stainless spring steel.
  • a coil spring 1 with an upper and lower end of the coil spring A is shown. It is important to note that at the end of the spiral spring 1, a spiral spring end 2 is designed to be bent into the spiral spring 1 to form a hook 7.
  • FIG. 3 A side view of the spiral spring end 2 is made, from which it can be seen that the spiral spring end 2 is bent into a hook 7 in the spiral spring 1 at the upper and lower end of the spiral spring A.
  • the coil spring end 2 is given round.
  • a hook 7 is thus created, which serves to connect the respective spiral springs 1 to one another.
  • the rope guide There are actually countless possibilities when it comes to designing the rope guide. You can attach the rope to the first and last existing eyelet by means of a loop and pull it straight through the other eyelets or pull the rope through all the eyelets of the spiral spring ends 2 and connect the rope ends together. It is important that the rope is passed through all eyelets so that they can turn 180 degrees but prevent them from twisting out.
  • the rope is advantageously made of polyester.
  • a retaining clip 8 is shown, which is preferably useful for clipping the seat pad 6 to the corresponding seating furniture.
  • This retaining clip 8 advantageously consists of a braided bend 9, which is introduced into the braid of spiral springs 5 with a kink 11 depending on the size of the seat and a seat holder 10 which is anchored below the chair.
  • This retaining clip 8 can vary in size depending on the seating furniture.
  • the braided bend 9 is introduced into the braid of spiral springs 5 at the respective end and at certain points, and the seat holder 10 is attached to the seating furniture via the bend 11.
  • the measurements taken from the Figure 4 can be seen, can only be seen as an exemplary embodiment and can change depending on the seating furniture and the size of the seat pad 6.
  • the back seat pad developed to complement the inventive seat pad for the seat has the task of allowing air to circulate through a gap between the back and the seat back. This is achieved with a spacer fabric with a thickness of 8 to 12 mm.
  • the knitted spacer consists of a polyester mesh with a width of about 2 to 10 mm on the front and back.
  • the two sides are connected by extremely thin threads, so-called pile threads, and thus keep the distance.
  • the strength of this connection is so high that it cannot be pressed together with the back and such a constant distance is always guaranteed.
  • This material is processed using ultrasonic cut-off welding.
  • a special anti-slip coating is applied to the back towards the backrest.
  • This coating prevents slipping on the backrest and therefore does not require any additional straps or cords to attach it to the seat.
  • the back section is fastened by two straps, which are connected to each other by a slider so that they can be adjusted in length, and thus the back section is hung over the headrest.
  • the straps are so long that all common types of backrests are covered.
  • the knitted spacer is framed around the edge by a polyester tape, which can be colored, and connected to one another by sewing, gluing or welding. Furthermore, two parts can be connected to each other. This creates a combined seat and backrest area.
