Design and packaging of vehicle interiors and cockpits had become a science on itself, particularly in recent years where safety is paramount. Significant experimental efforts have been made to study driver reach and barriers as they have direct effect on performance and safety. This paper presents a rigorous formulation for addressing the reach envelope and barriers therein of a 3-point restrained driver and compares with a lap-restrained driver. The formulation is based on a kinematic model of the driver, which has the upper body and arm characterized as a 7 degree of freedom DOF for unrestrained and 4DOF for 3-point restrained. Those kinematic equations are further developed to address crossability analysis. Visualization of such barriers and their crossability results within the reach envelope provide significant insight into driver performance and reach zones.
