This report summarizes the work done by the Society of Automotive Engineers in cooperation with the National Bureau of Standards aimed at setting up minimum standards for seat belts for use in motor vehicles.

As a result of the legal interpretation of Public Law 88-201, it was necessary that these standards apply to shoulder harnesses and special children's restraint systems in addition to lap belts. This report will summarize the activities of the separate groups involved in the program and cover in some detail the proposed standard which has been developed as a result of their endeavor.
