NAVAIRTESTCEN was tasked to examine reported problems with aircrew torso restraint garments. Five sources of information were used for the investigation into the reported problems: Development of a logic tree for analysis of reported inadequate restraint of aircrews; examination of Medical Officer's Reports from 1969 through 1976 pertaining to ejections from aircraft in which the MA-2 Integrated Torso Harness was a part of the restraint system; examination of Unsatisfactory Reports for the same period; solicitation of an Aircrew Personnel Restraint Questionnaire from aircrew assigned to high performance tactical aircraft; and a laboratory study of the biomechanics of -Gz restraint. The MA-2 Integrated Torso Harness was found to be inadequate in all respects for -Gz restraint and ineffective as a restraint garmet for -Gx and lateral (Gy) accelerative forces. Data were developed defining the effects of negative Gz upon the body, suggesting that it produces two separate components, off-seat travel and body stretch, each of which requires specific treatment by any proposed restraint system. Recommendations are made for immediate improvement of deficiencies in the design of the restraint harness and its related subsystems, and emphasis is placed on the need for reevaluation of restraint needs, mobility needs, and the comfort of the crewmember in future design efforts. Further research, development, and testing of a variety of harnesses is urged. (Author)
