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 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.
Rationale
This revision contains editorial changes to improve the document structure and clarity. No technical changes were made.

Issuing Committee
Driver Vision Standards Committee
The Driver Vision Standards Committee reports to the Vehicle Safety Systems Group of the Motor Vehicle Council. The Committee is responsible for developing and maintaining SAE Standards, Recommended Practices, and Information Reports related to road vehicle components and factors that affect an occupant's field of view. The Committee also provides input to the International Organization for Standardization (ISO) Road Vehicle Technical Committee's (TC22) Visibility Subcommittee (SC17). Participants in the SAE Driver Vision Standards Committee include OEMs, suppliers, consulting firms, government, and other interested parties.

* Redlines comparisons are available for those standards listed in the Revision History that contain a radio button. A redline comparison of the current version against a revision is accomplished by selecting the radio button next to the standard and then selecting 'compare'. At this time, Redline versions only exist for some AMS standards. SAE will continue to add redline versioning with ongoing updates to SAE MOBILUS.
