Product Code:SAE J941
Title:Motor Vehicle Drivers' Eye Locations
Issuing Committee:Driver Vision Standards Committee
Scope:This SAE Recommended Practice establishes the location of drivers驴 eyes inside a vehicle. Elliptical (eyellipse) models in three dimensions are used to represent tangent cutoff percentiles of driver eye locations.Procedures are provided to construct 95th and 99th percentile tangent cutoff eyellipses for a 50/50 gender mix, adult user population.Neck pivot (P) points are defined in Section 6 to establish specific left and right eye points for direct and indirect viewing tasks described in SAE J1050. These P points are defined only for the adjustable seat eyellipses defined in Section 4.This document applies to Class A Vehicles (Passenger Cars, Multipurpose Passenger Vehicles, and Light Trucks) as defined in SAE J1100. It also applies to Class B vehicles (Heavy Trucks), although these eyellipses have not been updated from previous versions of SAE J941. The appendices are provided for information only and are not a requirement of this document.This document applies to Class A Vehicles (Passenger Cars, Multipurpose Passenger Vehicles, and Light Trucks) as defined in SAE J1100. It also applies to Class B vehicles (Heavy Trucks), although these eyellipses have not been updated from previous versions of SAE J941.
