Abstract:

Analytical and design studies were conducted on the aircraft lap belt tightener mechanism. Substitution of a ball type initial lock mechanism for the Belleville spring increased the lap belt tightener tension load capacity and use of a high strength material increased the loop load capacity. A minor configuration change in the piston locking mechanism provided more reliable operation. In the final ballistic tests, the M67 cartridges were substituted for the M75. The M67 cartridge generated the desired gas pressure in the system and operated the lap belt tightener within the specified limits. Author
