seat pan height poplitedheight 2.5cm
cushion height height of heel Where 2.5cm is
introduced, based on the assumption that the seat
pan height should be slightly lower than
popliteal height to prevent impacting the thighs.
seat pan height work surface height sashaku
cushion height height of shoe heel When the
work surface height is fixed , te seat pan height
can be determined by subtracting sashaku from the
work surface height

viewing distance and b is the viewing angle the
two submodel are connected by VDT sashaku from
the relationship between the VDT screen centre
height and sitting eye height. When the opperator
faces the display screen, the centre of the
display screen should correspond to the natural
viewing angle of the operator. VDT sashaku in
this case represents
