COMPARISON OF YIELDING AND ELASTIC RESTRAINT SYSTEMS FOR CRASH PROTECTION

A comparison of the effectiveness of yielding and elastic restraint systems for crash protection was conducted. Mathematical models of elastic and yielding restraint systems were developed to show the effects of slack and yield at constant load. For a given peak restraint load it was shown that one inch of slack could reduce the allowable vehicle deceleration by 20 percent, but that 8 to 12 inches of yield could double the allowable vehicle deceleration. It was concluded that the performance of crash protective seat belts can be improved by the incorporation of energy absorbers which allow the restraint to yield at constant load. (X)
