Definitions

  • the invention relates to a cushion element for a couch or Seating furniture according to the preamble of claim 1.
  • upholstery elements can in particular as Upper mattresses can be used in beds, but also as Seat or backrest upholstery in seating. With such Elements must because of the inevitable diffusion Air core losses are regularly replenished.
  • US-A-4 306 322 is a generic Upholstery element known, which is designed as a top mattress with a fold-out integrated pump body, which via a one-way valve and a convertible three-way valve is directly connected to the air core of the mattress. To the The pump body is folded out to refill the air core and compressed manually.
  • the object of the invention is a generic To create cushioning element in which the air core automatically dosed is replenished. This task is accomplished by the specified in the characterizing part of claim 1 Features resolved. Other features of the invention are the subject of dependent claims 2 to 10.
  • the body weight of the user creates zone-by-zone pressure.
  • This pressure which occurs increasingly at the beginning or end of use, particularly in the edge area of the top mattress, presses air out of the integrated pump bodies (1) into the unloaded air reservoir (2).
  • the two one-way valves (3) cause the air to flow in only one direction at a time.
  • the air displaced from the pump bodies (1) is compressed in the air reservoir (2) and serves as a reserve.
  • This compressed air reserve balances the pressure in the air core (4) up to the value that was set on the pressure regulating valve (5) using the scale (6). This compensation takes place at the latest when the top mattress is relieved. If the edge zone is relieved, the pump bodies (1) suck ambient air through the one valve by returning to their starting position.
  • the pump is now ready for further air supply.
  • the adjustable pressure regulating valve (5) together with the air compressed in the air reservoir (2) ensures precisely metered replenishment in the air core (4).
  • the scale (6) allows precise setting of the desired pressure and thus the required load capacity of the top mattress.
  • the top mattress is thus infinitely adjustable from soft to hard.
  • the body weight of the person using the top mattress squeezes the pump body (1) when the edge zone of the top mattress is loaded, thereby reducing its volume.
  • the air in the pump body is pressed through the air lines (7) and the one-way valves (3) into the air reservoir (2) and compressed there.
  • the body weight of the person using the top mattress ensures that the air pressure in the reservoir (2) is always present via the integrated air system, which results in refilling and constant load-bearing capacity of the air core (4).
  • the air core (4) in the top mattress is always filled as far as desired by the loads on the system that occur at intervals, simply by using the top mattress, i.e. it is set on the scale (6).
  • Upper mattresses equipped with air cores (4) also fit largely on the supporting document.
  • adjustable bottom mattresses are head and foot elevations or sitting positions possible without further ado.
  • the adaptable and body-friendly air cushion is suitable thanks to the infinitely variable adjustability from soft to hard for the normal consumer as well as for therapeutic purposes.
  • Anti-decubitus effect becomes with long-lasting bedriddenness very appreciated. But there can also be others in the desired therapeutic effects can be achieved. It can, for example, several air chambers with the corresponding Pressure regulating valves are used. It is for therapeutic applications also special types of air cores (4) conceivable.
  • Mattresses (cushions) for seating are in one Further development possible. The use of such offers Beds / upholstery which automatically use air refill also welcome addition in the therapeutic area or replacing previous options.
  • the pump body (1) and the reservoir (2) are manufactured made of airtight film (12).
  • the welded in a suitable place Hose ends (19) allow the admission of the Hose connector for the air hoses (7).
  • the tubular finished pump body (1) are also from the frame (9) cut, breathable foam filled. The guarantees a good air volume as well as perfect Resilience of the pump body (1) even after many years Use.
  • the one-way valves (3) are used so that air can only flow in one direction. This guarantees that perfect functioning of the pumping process.
  • the one for the air core (4) airtight film (12) is used with a thin Layer of foam (13) flame-laminated. This will be slide and foam connected homogeneously. After manufacturing the A layer of cotton terry cloth (14) is applied to the air core (4).
  • the pressure regulating valve (5) is infinitely adjustable in the range from 0 to 60 millibars.
  • the attached scale (6) allows one precise and continuous adjustment of the air pressure in the air core (4) and thus the load capacity of the top mattress.
  • the open-celled and thus constructed as a load-bearing element air-permeable foam frame (9) gives the top mattress the necessary lateral stability.
  • the Components of the air supply installed.
  • the efficiency of the Air supply increased enormously.
  • Of the Air core (4) is made of airtight film (12). This is one-sided with a thin layer of foam (13) flame laminated. This homogeneous Connection in no way hinders the welding of the film Wise, however, serves for isolation and enables later Application of further material, for example terry cloth (14) on the air core (4).
  • Unlaminated film is used for the Intermediate webs (8) of the air core as well as for the connecting strip (24 ').
  • a welded in a suitable place Molding (17) serves as an air inlet / outlet for the air core (4). After welding the intermediate webs (8) and the The connecting strip (24 ') ends the welding of the corners the basic construction of the air core (4).
