ABSTRACT:
A release device for releasably coupling a first object to a second object includes a first member (10) adapted to be coupled to the first object and a second member (20) adapted to be coupled to the second objects. A latch mechanism (12, 21, 28) releasably couples the first member (10) to the second member (20). A time delay mechanism (22, 23, 24, 26, 27) permits the latch mechanism (12, 21, 28) to decouple the first and second members (10, 20) only after a time interval has elapsed from initiation of the decoupling of the first and second member (10, 20).
