HUMAN MEASUREMENTS AND PERFORMANCE IN RETRACTING SEAT BELTS

A study of 60 male and 60 female adults was conducted with a view to determining some of the chief criteria controlling the dimensional suitability of the driving position of a passenger car, when a retracting lap/sash belt is worn. The report includes data on body weight, seated height, head restraint height, seated arm reach and the location of pelvic restraint. The subjects were introduced to seat belt buckles of various designs and it was found that they had difficulty in securing and releasing buckles with which they were not familiar. These difficulties were quantified in terms of times to secure and release, and studied by means of movie photography and other techniques. It was concluded that the location of hand and foot controls should be separately adjustable, that arm reach data published by Chaffee for lap belted subjects were similar to the new data for retracting lap/sash belts, that head restraints made to Australian design rules are not high enough nor do they extend sufficiently downwards, that these rules do not specify adequately the location of the lap strap and that, having regard for emergency situations, Australians should not be exposed to novel forms of seat belt buckle.
