Figure 1 shows a descriptive drawing of the ErgoAir^® seat air bladder system. The bladder system consists of two air chambers, one forming the seat bottom bladd and the other forming the seatback bladder. Tubes or ports, as shown in Figure 1 and 2 facilitate rapid airflow back and forth between the seat bottom and seatback air chambers. The form and structure of the seat air bladder are maintained by seat bottom and seat back open-cell foam panels, as shown in Figures 3 and 4. A series of holes are cut lengthwise and widthwise longitudinally in these foam panes, as shown in Figures 3 and 4, to facilitate the rapid flow of air throughout the open-cell foam matrix of these panels. The foam panels are sandwiched between an upper and lower impervious outer cover, as shown in Figures 2 and 5. The upper and lower layers of the impervious outer cover are bonded to the entire upper and lower surfaces of the seat bottom and seatback foam panels. These layers are sealed around their perimeters and in between the two foam panels, as shown in Figure 2, forming a seat bottom air chamber and a seatback air chamber. Flexible tubes placed between the seat bottom and seatback air chambers are sealed between the upper and lower impervious layers ,as shown in Figure 2. These tubes form air vents that facilitate the rapid flow of air between the two air chambers. The structure and form of the seat air bladder system are protected by U.S. Patent Number 8,033,600.
