SAE 2005版本中，后排有效腿部空间规定的比较多，兄弟们是咋理解的？要不要将脚左右偏127mm后量取脚踝点至H点啊？
SAE J1100 Revised SEP2005
L51:Effective Leg Room (Passengers) The dimension measured along a line from the ankle pivot center
to the SgRP plus 254 mm with the heel of the shoe at the FRP
and the bottom of the shoe at the FPA.
Note 1: For long-coupled seating, leg room is measured with the
shoe at its most forward location within a lateral space 127 mm
either side of the occupant centerline regardless of the ankle angle.
The shoe is not located at the FRP or FPA.
Note 2: For short-coupled seating, leg room is measured with the
shoe located at the FRP. When the front of the shoe interferes
with the preceding seat, the amount of seat track travel needed to
clear the interference is subtracted. If the preceding seat does not
adjust, the horizontal interference is subtracted.
