Pressure Sensitivity of Buttock and Thigh as a Key Factor for Understanding of Sitting Comfort

In seating comfort research, it is known that the pressure should not exceed a certain threshold from viewpoint of tissue compression and be widely distributed. However, its ideal distribution defined in past research. It also comfortable always constant has individual differences. assumed this due to influence differences body shape, such as skeletal shape flesh seated person, sitting posture, but mechanism been clarified by analyses including these factors. From above, considered cannot explained only mechanical state. study, we focused on sensitivity thighs buttocks performed an analysis assuming automobile seat. We determined exponent Steven’s power law for seat measuring local perceived load felt same feeling at reference point, 29 participants were measured classified them into 4 types. The five was using experimental converted distribution. results show perceived. Analysis suggests uniform falls within range minimum pressure.
