Ventilated seat
First Claim
1. 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 operatively sealed to the air impermeable top, and an opening configured to be coupled to an air mover, the bag top including a plurality of holes arranged and sized to provide air movement through the bag only through the plurality of holes; and
a spacer located within the bag;
wherein some of the holes are located nearer the bag opening than other holes and each hole has a cross-sectional area, the holes located substantially the same distance from the bag opening forming a group having a total cross-sectional area, the bag including more than one group of holes, the total cross-sectional area of each group of holes being greater than the total cross-sectional areas of any groups of holes nearer the bag opening.

Abstract
A ventilated vehicle seat includes a bag formed from impermeable materials enclosing a spacer material. The latter preferably includes upper and lower netting sheets and fibers extending between the netting sheets, the fibers being sufficiently resilient to prevent total collapse of the spacer material when the seat is occupied. An air mover that forces air into or draws air from the bag may be coupled to the air space between the air impermeable layers of the bag. Groups of holes are provided in the top of the bag, and the total cross-sectional areas of the groups of holes are preferably selected to equalize air flow over the seating surface, rather than having all the air flow through the holes nearest the fan. An optional, porous heating layer may be located above the bag.
