Dear Mr. Niguma: This is in reply to your letter of January 23, 1971, to Mr. Rodolfo A Diaz, regarding attachment bolts used to secure seat belt assemblies to a motor vehicle.; The intent of the requirement in paragraph S4.3(c)(1) of Standard 20 is to assure that inadequate attachment bolts will not be used to attach seat belt assemblies to the vehicle. This paragraph does not require that the specific models of vehicles be listed on the label. It provides that if a seat belt assembly is *designed* for use in specific vehicles in which *only* one end of a belt assembly can be attached by a single bolt, then the bolt need only have a breaking strength of 5,000 pounds.; It should be noted, however, that paragraph S4.1(1) of the Standar requires the manufacturer of seat belt assemblies for aftermarket use to furnish an instruction sheet stating whether the assembly is for universal installation or for installation only in specifically stated motor vehicles. If, as you state, the seat belt assemblies used in MAZDA vehicles are designed exclusively for specific models, such models must be listed on the installation instruction sheet.; Please contact us if we can be of further assistance. Sincerely, Clue D. Ferguson, Director, Office of Crashworthiness, Moto Vehicle Programs;
