SAE J287-1988 (R)DRIVER HAND CONTROL REACH

Foreword-This document has not changed other than to put it into the new SAE Technical Standards Board Format.

1. Scope-This recommended practice describes boundaries of hand control locations that can be reached by desired proportions of different driver populations in passenger cars, multi-purpose passenger vehicles, and light and medium trucks. This practice is not applicable to heavy trucks.
1.1 Introduction-The description of driver hand control reach envelopes was developed using data acquired from test subjects performing reach tasks in test fixtures simulating a range of actual vehicle configurations
(Reference 1 and 21). The test subjects included equal numbers of men and women selected to represent the
(United States) driving population on the basis of stature and age, and were tested both with and without upper torso three-point restrain(a diagonal non-extending shoulder strap attached separately to the lap belt, that is, not a continuous loop). The envelopes constructed using the non-extending shoulder and lap belt are meant to define a restrained reach and the envelopes constructed using the lap belt only will describe an unrestrained upper torso hand reach. The hand reach envelopes are three-dimensional surfaces described in table form and can be referenced to a particular vehicle seating configuration according to procedures described in Sections 5 and 6. Only the 95% boundaries are presented in the tables.
