Abstract
A test fixture for simulating the inflation profile of a vehicle air bag. The test fixture includes a cavity block containing compressed nitrogen at a first predetermined pressure, and accumulator containing compressed nitrogen a second higher predetermined pressure, a diffuser containing an air bag at ambient pressure, a first rupture disk intermediate the accumulator and the cavity block adapted to rupture at a third predetermined pressure intermediate the first and second predetermined pressures, and a second rupture disk intermediate the diffuser and the cavity block adapted to rupture at a fourth predetermined pressure intermediate the first and second predetermined pressures. A valve is connected to the cavity block to selectively open the latter to release the mixture from the cavity block, to thereby increase the pressure differential across the first rupture disk to rupture same and then subject the second rupture disk to the released mixture to rupture same and, thence, subject the diffuser to the released pressure to inflate the air bag.
