SAE J941

Annotation of standard text SAE J941 :

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.
