Study on the Relationship Between Sitting Time Tolerance and Body Pressure Distribution
By using body pressure measure system, the pressure distribution data and tolerable sitting time of 12 subjects in three different seats were recorded. The paper analyzes the relationship between sitting time tolerance and pressure distribution index and the effect of time on sitting comfort, provides a theoretical basis for reasonably optimizing design of cushion and evaluation of sitting comfort from the view of the human engineering. Experimental results show that the softer the cushion is, the longer tolerance sitting time is. And softer cushion will improve sitting comfort. The quantitative relationship between sitting time tolerance and body pressure distribution index was determined.
