Abstract

Shoulder support of seat is considered to affect driver's ease-of-steer feeling. During virtual slalom maneuver on a six-axis shaker, driver's motions and the forces and torques applying to steering wheel and seat back were measured in four different shapes of seat back. Then, the line of action regarding these forces and the glenohumeral joint torque about the axis parallel to steering rotation axis were estimated. The results indicate that the seat back force keeps applying to driver's moving scapula on outer side of a turn, glenohumeral joint torques contributing to steering wheel rotation are reduced, thereby possibly enhancing ease-of-steer feeling.
