THE RELATIONSHIP BETWEEN SAFETY BELT USAGE AND THEIR CONFIGURATION

In the fall of 1972, safety belt usage (lap belt only or lap/shoulder combination) was observed for more than 9,000 front seat occupants of certain late model automobiles in California operated in low speed and high speed driving situations. Data were obtained for Chrysler, Ford and General Motors passenger cars for model years 1968 through 1971. Belt configuration is defined across three design features -- (a) push button vs. lift latch buckle, (b) manual vs. automatic belt adjustment, and (c) 3-point vs. 4-point belt. At the 5% significance level, it does not appear that belt usage is a function of vehicle age or vehicle manufacturer. Moreover, only two of fourteen relevant tests support the hypothesis that usage is a function of belt configuration. /HSRI/
