Abstract
A buckle system for release of a crew member's harness from a parachute. The buckle system has a frame which holds the harness. A tang assembly holds the parachute strap and snaps into the frame. The tang assembly is held by a latch which pivots between a closed position and an open position. The latch in turn is held by a lever which includes a cavity which holds the free end of the latch. When the lever is moved to an open position the latch is released. The latch has a spring which urges it into an open position. The result is a buckle system which can be opened with very little force being exerted on the lever. The lever is covered by a spring loaded cover. An automatic release is provided wherein a pyrotechnic charge opens the cover and lever and thereby releases the latch.
