Definitions

  • the invention relates to an air-conditioned seat according to the preamble of claim 1.
  • Such an air-conditioned seat is from the DE 202 19 733 U1 known.
  • a fan for example, a radial fan, below the seat - spaced from this-arranged.
  • Air is transported into an air distribution device in the seat cushion via a passage region below the seat, which comprises an air distribution structure on the underside of the seat surface, air ducts and air outlet openings on the upper side of the seat surface. Proceeding from this, the object of the invention is to develop such an air-conditioned seat.
  • FIG. 1 shows on the basis of a cross section of the structure of a backrest or a seat part 22, wherein the padding foam 1 on the side facing away from the sitting side (hereinafter referred to as B-side) is bounded by a nonwoven 2.
  • B-side the padding foam 1 on the side facing away from the sitting side
  • 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.
  • FIG. 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. FIG. 3 ).
  • the upholstery foam is formed from a 2-zone foam 10 (cf. 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 shows, moreover, 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, in the vicinity of the fan on the padding foam. 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 ). There are next to the air ducts 7 on the A-side adjoining air trenches 13 introduced into the foam 1, for example by milling. 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 reference on the A side ( FIG. 7 ). If these air trenches 13 are formed on the A-side so that they are in operative connection with two air ducts 7, an air-guiding device 5 with back-flushing can also be achieved. Air flows out of the fan through an air trench 8 on the B side, through a first air duct 7, then through an air trench 13 on the A side and back through a second air duct 7 which ends directly on the B side ( FIG. 8 ).
  • the inside of the air trenches 8 is formed with a flock composite foam 16 which stabilizes as a harder material.
  • a flock composite foam 16 which stabilizes as a harder material.
  • FIG. 10 the inside of the air trench 8 is strengthened by means of a sprayable harder material against stress.
  • This adhesive 17 may be a rubber skin.
  • FIGS. 16 and 17 show other ways to stabilize the air trenches 8 and / or 13.
  • a special shapes 26, 27 of the air trenches 8 and / or 13 is achieved.
  • To FIG. 16 be carried out in a first specific shaping 26 inclined walls, which are formed with an arcuate conclusion 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. Furthermore, in both cases, the danger of pushing through or slipping through in the area of the air trenches 8 and / or 13 is reduced, since these have a higher stability. It may be advantageous to generate a suction effect via the air distribution structure 6, as with the aid of FIG. 11 is shown.
  • 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.
  • FIG. 12 represents a further pattern of an air distributor structure 6 - here 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 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 radial fan 4, which is attached to the foam or disposed in the foam.
  • a sucking radial fan 4 which is attached to the foam or disposed in the foam.
  • FIGS. 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, in the previous description of the fan 4 according to the FIG. 5 embedded possible embodiment described and is fixed. Based on the sectional view (bottom view) and a bottom view (top view) of FIG. 18 First, the mounting solution "buttonhole solution" of a first embodiment will be explained.
  • 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 2 according to the first embodiment obtains (FIG. FIG. 18 ) Button-hole type cutouts 28, "buttonhole solution”, which are orthogonal to the mounting axis of the fan 4 from a mounting hole 30, the "buttonhole”.
  • 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 analogous to the upper representation of FIG. 18 a similar solution in a second embodiment, wherein instead of corresponding cuts 28 recesses 32 are executed.
  • 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 in each case in a bottom view in each case a third and fourth embodiment in which incisions 28 or recesses 32 in the fleece 2 is dispensed with and the overlapping areas 35 between fleece 2 and fan 4 arise because the "buttonhole" 30 thus the mounting opening through the fleece. 2 not round anymore, but according to FIG. 20 oval or according to FIG. 21 is formed slightly different from a round shape.
  • FIGS. 22 and 23 show the FIGS. 22 and 23 a first fastening solution with resilient retaining elements 36, which in FIG. 22 in a plan view of a fan and in FIG. 23 are shown in a side view on the fan.
  • the resilient holding element in a kind of barbs a fixation of the fan reaches 4.
  • the foam zone 12 of their dimensions and its contour to the fan 4 has already been adjusted 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 assumed its desired position, resiliently supported on the foam zone 12 ,
  • FIG. 24 represents a plan view of a fan 4 or a section through a fan 4.
  • FIG. 25 represents a plan view of a fan 4 or a section through a fan 4.
  • These are not resilient retaining elements 36, but to rigid support members 37, which are actually barb-like in the foam zone 12, in the Figures 22-25 is not shown, hook, according to FIG. 25
  • a plurality of holding elements 37 can be arranged. The possible multiple arrangement of course applies to the resilient support members 36 after the FIGS. 22, 23 ,
