Air-conditioned seat
An air-conditioned seat includes a seat area and a backrest, the seat area and/or the backrest being cushioned with foam. For climate-control, a ventilator, in particular a radial ventilator, is provided, which is in operative connection with an air distribution device in the foam of the seat area and/or the backrest, the air distribution device including an air distribution structure on the side (e.g., a B side) facing away from the seated person, as well as air-conducting channels toward the side (e.g., an A side) facing the seated person. The ventilator is to be disposed in the foam itself, on the B side. The air is transported to the A side via the air distribution structure in the form of air trenches introduced into the foam on the B side, and via the air-conducting channels.

wherein at least one of the seat part and/or the seat back is upholstered with foam, the air distribution device arranged in the foam, the ventilator in operative connection with the air distribution device;
wherein the air distribution device includes an air distribution structure on a B side facing an interior of the at least one of the seat part and/or the seat back and air-conducting channels toward an A side facing an exterior of the at least one of the seat part and/or the seat back;
wherein the ventilator is provided within the foam on the B side, the air distribution structure and the air-conducting channel adapted to transport air to the A side, the air distribution structure including as air trenches in the foam on the B side; and
wherein at least one air-conducting channel is formed by a tack trench, through which a cover web extends to fix a cover in place on the foam.
2. The air-conditioned seat according to claim 1 , wherein the ventilator is arranged as a radial ventilator.
3. The air-conditioned seat according to claim 1 , wherein an inner side of the air distribution device is stabilized by a composite foam.
4. The air-conditioned seat according to claim 1 , wherein an inner side of the air distribution device is stabilized by at least one of a sprayed-on, harder material, a rubberized skin, and/or a spray adhesive.
5. The air-conditioned seat according to claim 1 , wherein the air distribution device includes a ring channel structure that allows a circulating flow.
6. The air-conditioned seat according to claim 1 , wherein the air-distribution structure has a substantially star-shaped configuration.
7. The air-conditioned seat according to claim 1 , wherein at least one of air trenches on the B side and/or air trenches on the A side are stabilized by at least special form arrangement.
8. The air-conditioned seat according to claim 1 , wherein at least one of the foam, the seat back, and/or the seat part is delimited on the B side by a non-woven fabric having an installation opening, which in conjunction with a cavity arranged as an installation location of the ventilator, forms overlap regions, a flexibility of the installation opening for installation of the ventilator in at least one of:
with larger overlap regions by non-woven fabric cutouts with at least one of cuts and/or recesses; and/or
with smaller overlap regions by non-woven fabric cut-outs having special forms.
9. The air-conditioned seat according to claim 1 , wherein the ventilator is fixed in place in the foam.
10. The air-conditioned seat according to claim 9 , wherein the ventilator is fixed in place in at least one of the foam, a separate fixation layer, and/or a foam zone by at least one of a flexible and/or a rigid retaining device arranged at the ventilator.
11. The air-conditioned seat according to claim 1 , further comprising an air-permeable material arranged on the A side between the foam and a cover enclosing the seat toward an outside.
12. The air-conditioned seat according to claim 11 , wherein the air-permeable material includes at least one of a knitted spacer fabric, rubberized hair, and/or a reticulated foam.
13. The air-conditioned seat according to claim 1 , further comprising an air-permeable material arranged on the B side between the foam and a layer surrounding the foam.
14. The air-conditioned seat according to claim 13 , wherein the air-permeable material includes at least one of a knitted spacer fabric, rubberized hair, a reticulated foam, and/or a non-woven fabric layer.
15. The air-conditioned seat according to claim 1 , wherein the cover web extends along the tack trench and through an air trench extending transversely to the tack trench, on the B side and is fixed in place on the B side, and the cover web has at least one perforation in a region of the air trench to ensure an air flow through the air trench.
16. The air-conditioned seat according to claim 15 , wherein the cover web is made of a lattice web.
17. The air-conditioned seat according to claim 1 , wherein the foam includes foam zones of different types.
18. The air-conditioned seat according to claim 17 , wherein the ventilator is embedded in a separate foam zone that fixes the ventilator in place.
19. The air-conditioned seat according to claim 17 , wherein a foam having a harder consistency extends at least along the air distribution structure facing the B side and is adapted to stabilize the air distribution structure.
20. The air-conditioned seat according to claim 1 , wherein the air-conducting channels extend transversely through the foam, air trenches provided at an end of the air-conducting channels are disposed toward the A side and extend transversely to the air-conducting channels.
21. The air-conditioned seat according to claim 20 , wherein a zone including the air trenches is formed by a separate cut-foam layer having corresponding cut-outs in operative connection with the air-conducting channels.
22. The air-conditioned seat according to claim 20 , wherein the air trenches disposed toward the A side are connected to corresponding air-conducting channels to transport air from the ventilator to the A side, then via an air trench along the A side and from there, back to the B side for back flow.
23. An air-conditioned seat, comprising:
a seat area;
a backrest;
a ventilator; and
an air distribution device;
wherein at least one of the seat area and/or the backrest is cushioned with foam, the air distribution device arranged in the foam;
wherein the ventilator is in operative connection with the air distribution device, the air distribution device including an air-distribution structure on a B side facing an interior of the at least one of the seat area and/or the backrest and air-conducting channels toward an A side facing an exterior of the at least one of the seat area and/or the backrest;
wherein the ventilator has an aspirating effect, air being transportable from the A side to the B side; and
wherein at least one air-conducting channel is formed by a tack trench, through which a cover web extends to fix a cover in place on the foam.
