<p>A vehicle seat includes posture enhancing systems to increase occupant comfort. In addition to pelvis support, the seat includes a pivotable thorax and a height adjustment therefor, having a range of adjustment of about 100 mm to accommodate different female and male occupants having different skeletal lengths. The correct positioning of the second pivot point is designed to provide a lumbar curvature which simulates that of a standing occupant. In its most simple form, the seat includes a pelvis support, a thorax pivot mechanism to allow forward movement of the thorax area and reclining of the shoulders and a linear actuator mechanism to allow accurate positioning of this pivot mechanism for the skeletal height for the occupant.</p> |
