Abstract

A ventilation system comprises a seat, a first fan, and a second fan. The seat has an upholstery part that includes a shaped body. The shaped body has a bearing surface, a rear side opposite the bearing surface, a first opening extending generally from the bearing surface to the rear side, and a second opening. The first fan is coupled to the first opening and is configured to generate a first flow of air generally perpendicular to the bearing surface. The second fan is coupled to second opening and is configured to generate a second flow of air generally transverse to the first flow of air.

Claims

1-18. -18. (canceled)

19. A ventilation system comprising:

a seat having an upholstery part, the upholstery party including a shaped body, the shaped body including;

a bearing surface;

a rear side opposite the bearing surface;

a first opening extending generally from the bearing surface to the rear side; and

a second opening;

a first fan coupled to the first opening and configured to generate a first flow of air generally perpendicular to the bearing surface; and

a second fan coupled to the second opening and configured to generate a second flow of air generally transverse to the first flow of air.

20. The ventilation system of claim 19, wherein the upholstery part is a seat cushion.

21. The ventilation system of claim 19, wherein the first fan is one of an extractor fan and a blowing fan.

22. The ventilation system of claim 21, wherein the second fan is the other one of an extractor fan and a blowing fan.

23. The ventilation system of claim 19, wherein the first fan is configured to direct the first flow of air from the bearing surface of the shaped body to the rear side of the shaped body.

24. The ventilation system of claim 23, wherein the second fan is configured to direct the second flow of air into the shaped body.

25. The ventilation system of claim 19, wherein the first fan is configured to direct the first flow of air from the rear side of the shaped body to the bearing surface of the shaped body.

26. The ventilation system of claim 25, wherein the second fan is configured to direct the second flow of air out of the shaped body.

27. The ventilation system of claim 19, wherein the shaped body includes a first duct for conveying the first flow of air and a second duct for conveying the second flow of air.

28. The ventilation system of claim 27, wherein each of the first duct and the second duct are open toward the bearing surface of the shaped body.

29. The ventilation system of claim 28, wherein the second duct substantially surrounds the first duct.

30. The ventilation system of claim 29, wherein first opening is arranged eccentrically on the shaped body.

31. The ventilation system of claim 29, wherein the first duct has a first end and a second end and wherein the first end is coupled to the first opening.

32. The ventilation system of claim 29, wherein the first duct includes multiple ducts, each of the multiple ducts having a first end and a second end, the first end of each of the multiple ducts being coupled to the first opening.

33. The ventilation system of claim 32, wherein each of the multiple ducts extend radially away from the first opening.

34. The ventilation system of claim 33, wherein each of the multiple ducts has a length, and wherein at least two of the multiple ducts have different lengths.

35. The ventilation system of claim 32, wherein each of the multiple ducts are parallel to one another.

36. The ventilation system of claim 32, wherein the second end of each of the multiple ducts is closed.

37. The ventilation system of claim 36, wherein the second end of at least one of the multiple ducts is expanded.

38. The ventilation system of claim 37, wherein the second end of the at least one of the multiple ducts is circular.

39. The ventilation system of claim 37, wherein the second end of the at least one of the multiple ducts is elliptical.

40. The ventilation system of claim 29, wherein the second duct is coupled to the second opening.

41. The ventilation system of claim 40, wherein the second duct includes a first end and a second end, the first end being coupled to the second opening.

42. The ventilation system of claim 41, wherein the second end of the second duct is closed.

43. The ventilation system of claim 42, wherein the shaped body includes a third opening coupled to a portion of the second duct.

44. The ventilation system of claim 40, wherein the upholstery part includes:

an air-permeable intermediate layer disposed proximate the bearing surface of the shaped body; and

an air-permeable covering material disposed on the side of the intermediate layer opposite the shaped body.

45. The ventilation system of claim 44, wherein the air-permeable covering material is stretched onto the shaped part.

46. The ventilation system of claim 44, wherein the intermediate layer includes an air-permeable rigid plate, an air-permeable pad, and an air-permeable heating mat.

47. The ventilation system of claims 46, wherein the rigid plate is disposed proximate the bearing surface of the shaped body and covers at least a portion of the first duct and the second duct.

48. The ventilation system of claim 47, wherein the pad is disposed proximate the side of the rigid plate opposite the bearing surface of the shaped body.

49. The ventilation system of claim 48, wherein the pad comprises rubberized hair.

50. The ventilation system of claim 48, wherein the edges of the pad are sealed.

51. The ventilation system of claim 48, wherein the heating mat is disposed proximate the side of the pad opposite the rigid plate.

52. The ventilation system of claim 51, wherein the heating mat includes a sensory mechanism operatively coupled to at least one of the first fan and the second fan so as to allow the sensory mechanism to control the operation of the at least one of the first fan and the second fan.

53. The ventilation system of claim 51, wherein at least one of the first fan and the second fan is configured to be operated manually.
