Evaluation of Passive Belts for Different Size Occupants

摘要

The report presents results from fifteen additional sled tests of the Volkswagen passive belt restraint system with Part 572 50th percentile male dummies in 90 degrees lateral, 30 degrees oblique and frontal impacts. The main objective of these tests was to examine how the performance of the restraint was affected by different orientations of the belt within the comfort zone. The test data exhibit a trend of improved performance as the belt is positioned higher and at a steeper angle across the torso in that the tendency to roll over the belt is reduced. It is concluded that the proposed belt fit compliance test procedures do not yield repeatable and realistic results for the belt position and hence are unsatisfactory for the intended purpose.
