Fig. 7.29 Pressure distribution of male volunteer on the E VO P ORE HRC 150 P soft foam mattress
at a minimum membrane internal air pressure of approximately 10 mbar and b at maximum
membrane internal air pressure of approximately 22 mbar
Fig. 7.30 Comparison of interface contact pressure of the female volunteer and the system LS2
related to the mattress material at a 10 mbar and b 20 mbar membrane internal air pressure
Figures 7.30 and 7.31 provide an overview of the results outlined previously.
The lowest interface contact pressure was found with the mattress foam material
S AF 6060, followed by HME7. The highest interface contact pressure occurred with
E VO P ORE HRC 150 P .
7.1.7.5 Comparison of Test Results with Simulation Data
Figures 7.32 and 7.33 compare pressure mapping test data with simulation data at
a minimum membrane pressure (10 mbar) and at a maximum membrane pressure
(20 mbar). Little difference in interface pressure stress was detected with regard to
