Description / Abstract:
This SAE Recommended Practice establishes the location of
drivers' 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.
