Abstract:
1. An apparatus for regulating a temperature of a body support structure comprising: a plurality of air bladders defining a plurality of control zones, each of the plurality of air bladders having, an air inlet and an air outlet; a plurality of temperature sensors, wherein at least one temperature sensor is coupled to each of the plurality of control zones to detect a temperature of air passing through the control zones and provide an output signal indicative thereof, a circulator coupled to the air bladders and configured to move air from the air outlets to the air inlets; a temperature modulator coupled to the air bladders and configured to alter the temperature of air moved by the circulator, and a controller coupled to the circulator, the temperature modulator and the temperature sensors to control the temperature in each of the plurality of control zones based on the output signals from the temperature sensors.
