Samenvatting
Two subjects succeeded in tolerating exposures to simulated car crashes involving velocity changes of over 30 mph and peak accelerations of over 21 g, when using a conventionally configured restraint system of advanced design, and applying techniques of body posturing and muscular tensing. The three-point belt restraint, containing energy-absorbing fiber bundles, was integrated with a padded, bucket, car seat. Although both subjects utilized head flexing, body muscular tensing, and leg bracing to withstand the applied forces, the specific manner in which each achieved this goal was somewhat different.
