Claim 0:
1. A temperature management system for an occupant supporting device comprising:
an air distributing device having a body structure, in a form of a bag having a separate spacer disposed therein, extending between opposing ends along a longitudinal axis, the air distributing device having an air inlet, a first air outlet, and a second air outlet, all three of which are located adjacent to one another at one of the opposing ends of the body structure; wherein the body structure has an upper side facing an occupant and a lower side in opposition to the upper side, the upper side and the lower side disposed along a transverse axis, the air inlet, the first air outlet, and the second air outlet being located on the lower side; wherein the air distributing device comprises two guide elements formed in the spacer for guiding the airflow from the air inlet to the first air outlet and the second air outlet;
a main power device having an air outlet connected to the air inlet of the air distributing device with an inlet duct, the main power device having an air inlet connected to the first air outlet and the second air outlet of the air distributing device with an outlet duct, the main power device circulating air through an air-circulating circuit within the air distribution device; and
a temperature adjusting device for adjusting a temperature of the air in the air-circulating circuit,
wherein an airflow, which has been temperature adjusted by the temperature adjusting device and which flows out of the air outlet of main power device, comprises at least a first portion of the air flow which flows through the inlet duct and into the air inlet of the air distributing device and a second portion of the airflow which returns back to the air inlet of the main power device through the outlet duct after circulating within the air-circulating circuit, and wherein the airflow which has returned back to the main power device is further adjusted by the temperature adjusting device and re-circulated in the air-circulating circuit; and
wherein the airflow flows from the air inlet along a central longitudinal axis toward one of the opposing ends and then turns and flows in an opposite direction along opposing edges of the air distributing device to the first air outlet and the second air outlet.
