Dear Mr. Dandy: This is in reply to your letter of September 25, 1972, concerning th application of S4.3(c) of Standard No. 209 to an upper torso anchorage bolt used to attach a seat belt assembly that has a continuous length of webbing for upper torso and pelvic restraint.; Our letter of July 20, 1972, to Standard Triumph, to which you refer did not rule directly on the question of whether a bolt on the upper torso side of a continuous loop assembly would be considered to secure the pelvic restraint' within the meaning of S4.3(c). It is our opinion that some part of the pelvic force is transmitted to such a bolt and that it is therefore required to conform to S4.3(c). Because the bolt cannot be used for more than one assembly, the applicable force requirement is 5,000 pounds.; Sincerely, Richard B. Dyson, Assistant Chief Counsel
