  • FIG. 1 shows, on the basis of a cross-section, the construction of a backrest or a seat part 22, wherein the upholstery foam 1 is delimited by a fleece 2 on the side facing away from the seated person (which is referred to below as B-side).
  • B-side On the seated side (hereinafter referred to as A side), the foam is covered by a cover 3.
  • a radial fan 4 is provided, which is arranged vibration-damped in the foam itself and that on the B side.
  • the seat surface or the backrest furthermore have an air distribution device 5, which here has an air distributor structure 6 and air ducts 7 arranged transversely thereto.
  • the air distribution structure 6 consists of directly introduced into the foam air trenches 8 or Air channels that extend along the B side and not from a spacer fabric layer. Air is thus sucked by the radial fan 4 in the foam, then distributed over the seat cushion or backrest cushion by the air trenches 8 of the air distribution structure 6 and then transported via the air ducts 7 on the A side of the seat part (see arrow).
  • the inventively proposed seat can be equipped in principle without spacer knitted fabric and thus without a separate air-permeable layer.
  • the air-conducting channels 7 and trenches 8 are integrated into the foam cushion.
  • spacer knitted fabric can then be arranged both on the A- and on the B-side of the backrest or the seat part 22.
  • Figure 2 shows the arrangement of a spacer fabric 9 or the rubber hair between the foam 1 and the cover 3 on the A-side.
  • the spacer fabric 9 or rubber hair can be arranged on the B side, namely within the air trenches 8 of the air distribution structure 6 (FIG. 3).
  • the upholstery foam is formed from a 2-zone foam 10 (see FIG. 4).
  • the A side is formed with a softer foam, while the B side is formed of a harder foam, thus stabilizing the air trenches 8.
  • the zone boundary 11 between the lower harder foam and the upper softer foam extends above the air trenches 8. In this way, the radial fan 4 is stabilized and protected against stress.
  • FIG. 5 also shows that such a stabilization or fixation of the radial fan 4 is also achieved by a separate foam zone or foam layer 12 which is applied, preferably glued, to the upholstery foam in the vicinity of the fan. This separate foam thus holds the fan.
  • An air distribution structure with air trenches can also be introduced in the A side of the upholstery foam in addition to the B side (FIG. 6).
  • the air can then be delivered to larger distribution areas on the A side
  • Such larger air outlet areas on the A-side or air trenches 13 on the A-side can also be formed by separate cut foam pads 14. These are prepared with corresponding cuts or recesses 15 of the later air trenches 13 or distributor structures and arranged between the foam and the cover on the A side (FIG. 7).
  • FIGS. 9 and 10 show further possibilities of stabilizing the air trenches 8.
  • the inside of the air trenches 8 is formed with a composite flock foam 16, which stabilizes as a harder material.
  • FIG. 10 Another embodiment is shown in FIG. 10, in which the inside of the air trench 8 is strengthened against stress with the aid of a sprayable, harder material.
  • This adhesive 17 may be a rubber skin.
  • FIGS. 16 and 17 show further possibilities for stabilizing the air trenches 8 and / or 13.
  • the stabilization of the shape of the air trenches 8 and / or 13 by optimizing the load distribution or the force distribution on the air trench 8 and / or 13 is thereby a special shapes 26, 27 of the air trenches 8 and / or 13 achieved.
  • oblique walls are formed, which are formed with an arcuate termination in the direction of the seated end (A-side).
  • parabolic walls are executed in a second special shaping, wherein the closed region of the parabola is again designed in the direction of the seated end (A-side).
  • a load on the air trenches 8 and / or 13 results in this shaping 26, 27 to a smaller change in the cross section of the air trenches 8 and / or 13, so that the desired, predefined flow conditions are maintained substantially.
  • This structure has an overall circular shape and allows a circulating flow. Air is blown by the arranged on one side fan 4 in the manifold structure and is returned to the Einblastician again, in which case the suction effect arises.
  • the air ducts 7, which extend essentially transversely to it, are arranged to the A-side in order to transport the air to the A-side.
  • FIG. 12 shows another example of an air distributor structure 6 -in this case in a backrest foam.
  • the air flows on the left side via a main Hauptverteilerarm 18 and two side arms 19 along the B side of the backrest 20 and via this in the transverse air ducts 7.
  • On the right side a pattern with two main distribution arms 21 is shown.
  • the air air ducts 7, which extend from the B to the A side are used to transport the air air ducts 7, which extend from the B to the A side.
  • the Abheftgräben 23 can be used, which is for locking the cover or the reference lug 24 in Foam cushion available.
  • the reference lugs 25 may be perforated or perforated themselves and thus also extend transversely through an air trench 8 at the B side. This has the advantage that an air trench 8 can extend below a filing trench 23, which increases the variability of the patterns in the air distribution structures.
  • the invention includes a sucking fan 4, which is attached to the foam or arranged in the foam. In this way, with the help of the introduced into the cushion air distribution structure 6 and the air ducts 7, a cooling effect at the seated or a moisture removal (not shown).
  • Figures 18 to 25 show a simple installation and alternative additional mounting solutions of the fan 4 in the foam, especially in the separately provided for the fan 4 foam zone 12, embedded in the previous description of the fan 4 according to the possible embodiment described for Figure 5 and is fixed.
  • the mounting solution "buttonhole solution" of a first embodiment will be explained first.
  • the fan 4 must be introduced into the cavity 31 of the foam, in particular the separately provided fixing layer, which is designed in particular as a foam zone 12.
  • the underside (B side) of a seat or backrest is already provided with the fleece 2 during the production process.
  • the nonwoven fabric 2 according to the first embodiment of FIG. 18 is provided with cutouts 28 in the manner of a buttonhole - "buttonhole solution" - extending from a mounting opening 30, the "buttonhole”, orthogonal to the mounting axis of the fan 4.
  • the length of the incisions 28 depends on the flexibility of the fleece 2 used.
  • the fleece 2 covers the fan 4 in overlaps 35, so that this results in additional support for the fan 4
  • the cavity 31 in the foam zone 12 has already been produced according to the contour of the fan 4, so that the fan 4 actually only needs to be "threaded” or "buttoned” during assembly by the fleece 2.
  • FIG. 19 shows, analogously to the upper illustration of FIG. 18, a similar solution in a second embodiment, whereby cutouts 32 are made instead of corresponding cuts.
  • This second also shown in a bottom view second embodiment lends itself to less flexible nonwoven materials. As shown, other overlap areas 35 result.
  • FIGS. 20 and 21 each show, in a bottom view, a third and fourth embodiment in which incisions 28 or recesses 32 in the fleece 2 are dispensed with and the overlapping regions 35 between fleece 2 and fan 4 are formed by the "buttonhole" 30
  • the mounting opening through the web 2 is no longer round, but according to Figure 20 oval or slightly different from a round shape according to Figure 21 is formed.
  • FIGS. 22 and 23 show a first attachment solution with resilient support members 36 which in Figure 22 in a plan view of a Fan and are shown in Figure 23 in a side view of the fan.
  • the resilient holding element in a kind of barb fixation of the fan reaches 4.
  • the foam zone 12 of their dimensions and their Contour ago to the fan 4 has already been adapted in advance, so that the resilient holding elements 36 are pressed down accordingly during assembly to the fan 4 and, as soon as the fan 4 has taken its desired position, resiliently supported on the foam zone 12.
