Fixed Seat: Non-Driver CAD accommodation model
The Fixed Seat: Non-Driver CAD model is a parametric model that is intended to provide the composite boundaries representing the body of the defined target design population, including posture prediction. The boundaries defined, based on the Human Accommodation Reference Point (HARP) and seat back angle, include the resulting positions for the occupants’ helmet, eyes, knees, legs, shins, elbows, and boots. Clearances between the occupant and surrounding interior vehicle surfaces have been added per MIL-STD-1472G (e.g. head clearance required from head (helmet)). Direct vision zones have been added based on MIL-STD-1472G and SAE Recommended Practice J1050, Describing and Measuring the Driver’s Field of View, 2009.
The Fixed Seat: Non-Driver CAD model described in this verification report is applicable to ground vehicles with fixed seating positions often located in the rear of the vehicle. The fixed seats have no horizontal or vertical seat track adjustment and likely include a seat back that is also stationary. The user in this position has few seated tasks requiring interaction with the rest of the ground vehicle.
