Although complying with the provisions of the Australian design rules, the location of the safety belt sash anchorage point for lap/sash belts has in some cases been found to permit the sash strap to either fall off the shoulder of many wearers or to cause discomfort by pressing on their necks. The authors have developed a sash guide that can easily be fitted in practically any car that displays either of these problems, and effectively corrects the belt layout to one that is comfortable and convenient, without degrading the safety of the belt. Sash guides have been fitted to a range of cars about which complaints had been received, and favourable reports have come from the drivers concerned. The comfort features of the sash guide are mandatory provisions of new Australian design rules effective on 1st January 1975 . Meanwhile, existing cars may be corrected by fitting sash guides.
