Abstract:
The invention is directed to a body support assembly comprising (i) an upper cushion zone (6) and a lower cushion zone (7) and separated by a separation sheet (8). The cushion zones (6, 7) comprise of a compressible material which is permeable for air in all directions, (ii) a first flow path (10) for ambient air comprising an air inlet opening (11) at the bottom surface (3) of the support assembly, air displacement means (12), a first heat exchanger (13) and a single or separate air outlet opening (14) at the bottom surface (3) of the support assembly, (iii) a second flow path for air comprising an air inlet (19), air displacement means (20), a second heat exchanger (17), through the lower cushion zone (7), through openings (23) in the separation sheet (8) and through the upper cushion zone (6) and multiple air outlets (22) in the top surface (2). The heat exchangers (13, 17) are part of a Peltier effect unit (16) positioned within the cushion volume (4).
