Abstract
A seat belt system for motor vehicle applications incorporating a dual retractor restraint system with a portion of the seat belt webbing having a locally thick segment such as an inflatable seat belt portion. The dual retractors include electrically controlled actuating clutching mechanisms which operate to maintain the inflatable belt portion in a desired position relative to the upper torso of the seat occupant without requiring the inflatable belt portion to pass through the system D-ring or latch tongue or a high mounted retractor. When the occupant is donning the belt, the shoulder retractor is locked and the webbing is extracted from the lap retractor. Once the tongue is latched into the latch plate, the lap retractor is locked and movement of the occupant is permitted by allowing extraction of webbing from the shoulder retractor.
