Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
113 words
A release mechanism for connecting an extraction rocket pendant to a parachute harness comprising: a connector fitting adapted to be attached to a parachute harness; separable means for connecting the pendant to the connector, a manual actuating means, a thermal battery operably connected to the manual means for generating an electrical current, a pyrotechnic device mounted in the connector responsive to said electrical current for producing explosively a fluid pressure; said battery being connected to the pyrotechnic device by electrical conductors; said pyrotechnic device having means for delaying for a predetermined period of time the initiation of said fluid pressure, said separable means being responsive to the fluid pressure to release the pendant.
