Results of the SWOV-accident investigation prove that if there are any differences in the effectiveness of lap belts and three-point belts, these are so small that they cannot form a basis for giving preference to one type over the other. Furthermore, in spite of the results of this investigation which show some disadvantageous effects of diagonal belts (as compared to lap belts and three-point belts), involving a higher injury risk, which leads to the conclusion that general use of this type should not be favoured, a complete condemnation of diagonal belts seems exaggerated. The effectiveness percentages of both lap belts and three-point belts show independently very high values. It is justifiable to draw the conclusion that both lap belts and three-point belts are highly effective measures for safety in traffic. There is also an English version of this report.
