- 21. The ventilated seat assembly of claim 20, wherein the plurality of holes in the bag top are arranged and sized to provide a generally uniform air movement through the bag.
- 22. The seat assembly of claim 20, wherein the first distance from the bag opening is greater than the second distance from the bag opening.
- 23. The seat assembly of claim 22, wherein the total cross-sectional area of the first group of holes is greater than the total cross-sectional area of the second group of holes.
- 24. The seat assembly of claim 20, wherein the holes in the first group are the same size.
- 25. The seat assembly of claim 24, wherein the holes in the second group are the same size.
- 26. The seat assembly of claim 25, wherein the size of the holes in the first group is greater than the size of the holes in the second group.
- 27. The seat assembly of claim 25, wherein the size of the holes in the first group is different than the size of the holes in the second group.
- 28. A ventilated seat assembly for use with an air mover comprising:
a seat having a generally horizontal cushion and a backrest, at least one of the horizontal cushion and the backrest being ventilated and including:
an air-permeable decorative exterior trim cover; a bag including an air-impermeable top, an air-impermeable bottom, and an opening configured to be coupled to an air mover, the bag top including a plurality of holes, some of the holes being located nearer the bag opening than other holes and each hole having a cross-sectional area; and a spacer located within the bag; wherein the arrangement of the holes and the cross-sectional areas of the holes are configured to provide a generally uniform flow of air through the holes when the bag is coupled to an air mover.
- 29. A ventilated seat assembly for use with an air mover comprising:
a seat having a generally horizontal cushion and a backrest, at least one of the horizontal cushion and the backrest being ventilated and including:
an air-permeable decorative exterior trim cover; a bag including an air-impermeable top, an air-impermeable bottom, and an opening configured to be coupled to an air mover, the bag top including a first region a first distance from the opening and a second region a second distance from the opening, the first region and the second region having substantially the same area, the first region including a first set of holes having a first total cross-sectional area, and the second region including a second set of holes having a second total cross-sectional area; and a spacer located within the bag; wherein the first region is closer to the bag opening than the second region and the first total cross-sectional area is less than the second total cross-sectional area.
