This report on the differences in effectiveness of lap and three point belts (diagonal belts are also discussed) is based on data derived from three major types of study: the extensive accident investigation covering 22,000 drivers of Dutch passenger cars involved in accidents (1968-1971); a criterical assessment of reports on foreign accident investigations involving careful sifting with regard to statistical reliability; and thirdly the assessing of practical aspects such as the applicability of seat belts in cars, problems with the correct position of the anchorage points and the comfort of belt users. The results of the study indicate little difference in effectiveness between the lap belts and three-point belts, both of which are highly effective. Taking into consideration aspects of application and comfort, the lap belt is concluded to a very reliable safety means.
