Scope:

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 95 and 99% tangent cutoff eyellipses for a 50/50 gender mix, United States user population.

Nect 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 J 1050. 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 J 1100. It also applies to Class B vehicles (heavy trucks), although these eyellipses have not been updated from previous version of SAE J 941.

The appendices are provided for information only and are not a requirement of this document.
