Definitions

  • the present invention relates to a pneumatic cushion, particularly for use as a sitting, lying and reclining cushion.
  • Pneumatic sitting, lying and reclining cushions are known in the art. They comprise, for example, a plurality of juxtaposed communicating air tubes or air vessels, which can be inflated and deflated via a common valve, and therefore resemble the known airbed in structure and form.
  • a main problem associated with pneumatic cushions involves giving the cushion a predetermined form without making it hard and uncomfortable as a result.
  • a bladder made from flexible material will immediately take on a substantially spherical shape when inflated.
  • the person skilled in the art will be familiar with the use of inflexible fabrics cut to shape, combinations of air vessels or air chambers and/or webs.
  • pneumatic sitting cushion made up of air tubes placed side by side is disclosed in WO 94/07396.
  • the object of the present invention is to create a pneumatic cushion, particularly for use as a sitting, lying and reclining cushion, which offers good dimensional stability, is able to satisfy rigorous requirements in relation to sitting comfort and has a substantially smooth surface without bulges caused by air tubes.
  • the cushion should not become stiff or even hard, as is usually invariably the case when using many shaping webs.
  • the object of the present invention is to create a pneumatic cushion, particularly for use as a sitting, lying and reclining cushion, which facilitates a good design, deviating from the usual round, pneumatic forms, in addition, has a substantially smooth, bulge-free surface and, at the same time, guarantees a high standard of sitting comfort.
  • the structure should not become stiff or even hard, despite great freedom in the design options for its form.
  • the cushion should be capable of being produced simply and cost-effectively.
  • FIG. 1 a shows a schematic representation of a first embodiment in cross-section
  • FIG. 1 b shows a schematic representation of a first embodiment in longitudinal section (smaller scale);
  • FIG. 2 shows a schematic representation of a second embodiment in cross-section
  • FIG. 3 shows a third embodiment in cross-section
  • FIG. 4 shows a schematic representation of a fourth embodiment in cross-section
  • FIG. 5 shows a schematic representation of a fifth embodiment in cross-section
  • FIG. 6 shows a schematic representation of a sixth embodiment in cross-section.
  • FIG. 1 a shows a first embodiment in cross-section.
  • a not necessarily gas-tight, substantially inflexible or limited-extensibility casing 1 contains several webs 2 , which are likewise made from substantially inflexible or limited-extensibility material and divide the cross-section of the pneumatic structure into four chambers.
  • a textile fabric for instance, may be used as the limited-extensibility, substantially inflexible material.
  • the chambers are created by four star-shaped webs 2 radiating from a central axis 5 lying substantially lengthways inside the cushion to the casing 1 .
  • a gas-tight bladder 3 is inserted in each of these chambers.
  • This bladder 3 is made from a thin, gas-tight, flexible membrane, for example, PU film. It may be produced from sections of tube, for example, by heat-sealing the two ends together.
  • the bladders 3 are either each provided with a valve 4 , through which they can be individually pressurised, or the bladders 3 communicate via lines or openings and create networks of bladders 3 .
  • the casing 1 may, for example, be positively connected to the webs 2 simply and cost-effectively by sewing. The seams need not have costly gas-tight seals.
  • the casing 1 provides the cushion along with the webs 2 with its form and, in addition, offers the airtight bladders 3 protection from mechanical action. Primarily, the bladders 3 assume only a sealing function in relation to the pressure gas.
  • the shape of the cushion is determined by the cut of the substantially inflexible casing 1 and the form and configuration of the substantially inflexible webs 2 .
  • FIG. 1 b shows the first embodiment in longitudinal section A-A′. This figure is presented on a smaller scale to provide a better illustration than that of the cross-section in FIG. 1 a .
  • the webs 2 run over the entire length of the cushion.
  • the cushions can be produced simply and cost-effectively.
  • FIG. 2 shows a second embodiment in cross-section.
  • the cushion has eight chambers rather than four created by eight star-shaped webs 2 radiating from the central axis 5 to the casing 1 and the casing 1 .
  • a third embodiment is depicted in cross-section in FIG. 3 .
  • a further possible configuration of the webs 2 is shown.
  • the webs 2 have partial openings, which connect the bladders 3 to each another and enable the pressure to be equalised between the different bladders 3 .
  • a single valve 4 is sufficient to pressurise several networks of bladders 3 communicating through openings 6 .
  • the openings 6 represented by substitution in FIG. 3 , are present in accordance with the invention in communicating bladders 3 in the other embodiments, even if this is not evident from the cross-sections.
  • the webs 2 are disposed in a star shape around two central axes 5 .
  • FIG. 4 shows a fourth embodiment, in which the webs are positively connected to the casing 1 on both sides and come into contact with or penetrate each another.
  • the chambers are juxtaposed lengthways.
  • the bladders 3 are subject to different pressures p 1 , p 2 , p 3 . This means that the core of the cushion can be subject to a lower pressure, for example, making it softer than the edge of the cushion, or vice versa.
  • Each bladder 3 or each network of communicating bladders 3 is fitted with at least one valve 4 . Different pressure regimes are conceivable for all web 2 and casing 1 configurations in accordance with the invention, with openings or lines 6 added between the communicating bladders 3 .
  • FIG. 5 shows schematically a cross-section through a fifth embodiment.
  • a chamber in the cross-section is completely surrounded by webs 2 and is adjacent to further chambers on all sides.
  • the smaller bladders 3 which are disposed around the large inner bladder 3 , may be subject to a lower pressure, for instance, than the larger bladder 3 disposed in the centre. This produces a cushion with a soft surface and a compact core, which displays good sitting comfort without becoming badly deformed when a load is applied.
  • FIG. 6 shows a multi-layered sixth embodiment.
  • the webs 2 form a grid in cross-section with three layers of chambers laid on top of one another. At the ends, two chambers with bladders 3 inserted seal off the cushion. It is evident from this embodiment that the webs 2 need not necessarily be attached or sewn to one another in such a manner that continuous webs are formed in a horizontal and vertical direction, for example. Instead, the webs 2 can be staggered relative to one another, as on the side edges of this embodiment.
