Human Tolerance to Automatic Restraint Harness Activator Forces 650951
Onset rates at the buckle in G/sec., onset rates of the straps, initial and residual lock-in tension in the straps as well as strap reel-in velocity were recorded.
It was demonstrated, during static tests, that lock-in tension of the system for sustained restraint must be defined because of circulatory and respiratory effects. Pressure on nerve plexi may occur in the axillary area. Tolerance to high reel-in rates, high onset G's in excess of 1 × 104 G/second was demonstrated.
G tolerance levels from impact data are definitely not applicable to restraint harness systems without considerable modification when the force is being applied in a specific area.
