Characteristics of PU Foam at Long Term Static and Dynamic Loading

Abstract

Characteristics cushions from PU foam together with coat determine comfort automobile seats. Frame of car seat with cushion from PU foam and cover serve like body rest. Also perform safety rules, that are demanded on car seat. Cushion in car seat is basically manufactured from PU foam. Experimental testing their property investigate correlation between their characteristic and comfort. One type of experiment is combination static and dynamic loading in medium term time interval . Subject research and content hereof article is recognition transmission characteristics and contact pressures cushions from PU foams in time interval two o'clock in turns static and dynamically weight constant loading.
