Research and Development of an Advanced Inflatable Occupant Restraint System.

摘要

The research program was conducted to evaluate a current conventional inflatable occupant restraint system and to design and demonstrate an advanced inflatable restraint system which would provide improved protection for the right front seat occupant during frontal and oblique-angle frontal collisions. Impact sled tests provided base line data which established the performance criteria of a conventional air bag restraint system. Test results of the multiple cell air bag system demonstrate that,in contrast with the conventional air bag,the internal pressure in various sections of the bag (cells) can be independently controlled. The concept provides a means for tailoring the stiffness of various portions of the bag for improved control of occupant kinematics and accelerations. Other advantages were the ability to provide protection in multiple collisions and in oblique-angle frontal vehicle impacts. (Author)
