Definitions
- the present invention relates to a pneumatic cushion, in particular for use as a seat, recliner and backrest cushion according to the preamble of claim 1.
- Pneumatic seat, recliner and backrest cushions are known per se. They consist, for example, of a large number of communicating air hoses or air cores, which are lined up next to one another and which can be ventilated and vented via a common valve, and thus have the same structure and shape as the known air mattress.
- a major problem with pneumatic pillows is to give the pillow a predetermined shape without making it too hard and uncomfortable.
- a bladder of elastic material tends to have a substantially spherical shape as soon as it is inflated.
- the object of the present invention is to provide a pneumatic cushion, in particular for use as a seat, recliner and backrest cushion, which enables good moldability, is capable of meeting high demands in the area of seating comfort and has an essentially smooth surface without beads originating from air tubes features.
- the pillow should not become stiff or even hard, despite the great freedom in the design options, as is usually the case when many shaping webs are used.
- the object of the present invention is to provide a pneumatic cushion, in particular for use as a sitting, lying and reclining cushion, which is a good one Liche rounded pneumatic shapes allows different shapes, also has an essentially smooth, bead-free surface and at the same time ensures a high level of seating comfort.
- the structure should not become rigid or hard, despite the great freedom of design options.
- the pillow should also be easy and inexpensive to manufacture.
- La is a schematic representation of a first embodiment in cross section
- FIG. 1b shows a schematic illustration of a first exemplary embodiment in longitudinal section (reduced scale)
- FIG. 2 shows a schematic illustration of a second exemplary embodiment in cross section
- FIG. 3 shows a schematic illustration of a third exemplary embodiment in cross section
- FIG. 4 shows a schematic illustration of a fourth exemplary embodiment in cross section
- FIG. 5 shows a schematic illustration of a fifth exemplary embodiment in cross section
- Fig. 6 is a schematic representation of a sixth embodiment in cross section.
- Fig. La shows a first embodiment in cross section.
- a not necessarily gas-tight, essentially inelastic or low-stretch casing 1 contains a plurality of webs 2, which are likewise made of essentially inelastic or low-expansion material and divide the cross section of the pneumatic structure into four chambers.
- a textile fabric can be used as a low-stretch and essentially inelastic material.
- the chambers are formed by four webs 2 extending in a star shape from a central axis 5 lying essentially along the inside of the cushion to the shell 1.
- a gas-tight bladder 3 is inserted into each of these chambers.
- This bladder 3 is made of a thin, gas-tight, elastic membrane, for example of PU film.
- the bubbles 3 are each provided with a valve 4, via which they can be individually pressurized, or the bubbles 3 communicate via lines or openings and form groups of bubbles 3.
- the cover 1 can, for example, be connected to the webs 2 in a cost-effective and simple manner by sewing. The seams do not have to be sealed gas-tight.
- the cover 1 gives the pillow its shape together with the webs 2 and additionally offers the airtight bubbles 3 protection against mechanical influences.
- the bubbles 3 primarily take on only a sealing function with regard to the compressed gas.
- the shape of the cushion is determined by the cut of the essentially inelastic cover 1 and the arrangement and shape of the essentially inelastic webs 2.
- Fig. 1b shows the first embodiment in longitudinal section A-A '. For the sake of clarity, the scale of this representation was chosen to be smaller than that of the cross section in FIG.
- the webs 2 run the entire length of the pillow.
- FIG. 2 shows a second exemplary embodiment in cross section.
- the pillow has eight instead of four chambers, formed by eight webs 2, which run from the central axis 5 to the shell 1, and the shell 1.
- a third exemplary embodiment is shown in cross section in FIG.
- Another possible arrangement of the webs 2 is shown.
- the webs 2 partially have openings ⁇ which connect the bubbles 3 to one another and enable pressure compensation between the different bubbles 3.
- a single valve 4 is sufficient to pressurize several groups of bubbles 3 communicating through openings 6.
- the openings 6, shown in FIG. 3 are present in the case of communicating bubbles 3 in the other exemplary embodiments, even if it cannot be seen from the cross sections.
- the webs 2 are arranged in a star shape around two central axes 5. Fig.
- each bladder 3 or each group of communicating bladders 3 is equipped with at least one valve 4. Different pressure regimes are conceivable with openings or lines ⁇ between the communicating bubbles 3 for all arrangements of webs 2 and casing 1 according to the invention.
- Fig. 5 shows schematically a cross section through a fifth embodiment.
- a chamber is completely bordered in cross section by webs 2 and borders on all sides with other chambers.
- the smaller bubbles 3, which are arranged around the inner large bubble 3, can, for example, be subjected to a lower pressure than the larger bubble 3 arranged in the center Soft surface and firm core created, which has a good seating comfort, without deforming strongly under load.
- FIG. 6 shows a multilayer sixth exemplary embodiment.
- the webs 2 form a grid with three superimposed layers of chambers in cross section. At the ends, two chambers with inserted bubbles 3 close the pillow. It can be seen from this exemplary embodiment that the webs 2 do not necessarily have to be fastened to one another or sewn to one another such that continuous webs are formed in the horizontal and vertical directions, for example. Instead, the webs 2 can be arranged offset with respect to one another, as is carried out on the lateral edges in this exemplary embodiment. Further embodiments according to the invention can be generated by a person skilled in the art by freely combining features of various exemplary embodiments shown above.
