Upper Torso Restraint Systems 851848

A new SAE Aerospace Standard has been developed for upper torso restraint systems in anticipation of mandatory installation in 1986. Shoulder harness integration with pelvic restraint belts are described. Load and performance tests of complete assemblies are described. Details of the system include webbing, seat anchors, buckles, buckle mating plates, adjusters, and emergency locking retractors. Minimum performance requirements and tests for each component are prescribed in the new standard. Tests include effect of flame, light solvents, and abrasion of the webbing. The hardware must qualify for corrosion, temperature and durability. Entire assemblies must be tested to prescribed pelvic and harness loads. These tests are described.
