The research program was conducted to design, develop, fabricate and evaluate performance of a driver inflatable occupant restraint system for a full-size U. S. automobile within a combined analytical and experimental framework. The system included the energy-absorbing steering column, the special steering wheel, the inflator, the sensor and the air bag. Development of the system was to provide protection to the driver under a range of frontal force, barrier equivalent, impact conditions. With anthropomorphic dummies as test subjects, experimental crash simulations and crashes were carried out at various velocities with no restraint, with the lap belt only, with the lap and shoulder belt, and with the air bag system. The performance of the air bag system was evaluated by comparing its performance with other protective systems and with the baseline of no protective system according to the injury criteria established in FMVSS 208 and/or the criteria established in this report. Potential injury is appreciably less for the air bag installation than for the standard four-point harness, lap belt, or the unrestrained conditions for the forward-force collisions and simulations in this program. Analytically, air bag design parameters were also studied through mathematical model simulations. The mathematical model output correlated with the experimental results to a satisfactory degree. Performance of the system is good enough to warrant installation in vehicles on the road for "in service" evaluation in terms of reduction of fatalaties and injuries. /Author/
