Shear forces are known to +cause particular discomfort in static loading situations, +typically as when the passenger tries to sleep. + +The posture of the passenger is controlled by the backrest +angle. The bacrest offers pressure support for the back +of the human model but no tension support. This means that +forward leaning postures are realized by inclining the +seat forward and the body is not getting any support from +the backrest in this situation. + +The inverse dynamic analysis of the model inclines the +backrest backwards from an initial 10 degree forward +inclination to a 30 degree backward inclination, which +is on the very upper limit of coach class passenger seats. +-------------------------------------------------------- */ +Main = {}; \ No newline at end of file
