ABSTRACT:
The disclosure concerns a parachute release mechanism which comprises a harness connector for releasably connecting the risers of a main parachute canopy to a harness which is worn by a parachutist and which further comprises an actuating system for sequentially actuating release of the main canopy from the harness and for then effecting deployment of a reserve canopy from its compartment within a container. The actuating system includes first and second cables which are respectively employed to actuate release of the main canopy and to actuate deployment of the reserve canopy. The first cable is pulled to a predetermined extent to effect release of the main canopy. Pulling of the first cable beyond the predetermined extent deploys the second canopy. A sliding interconnection is provided between the first and second cables whereby the first cable moves relative to the second cable during the first predetermined extent of travel of the first cable but, thereafter, a release handle portion which is associated with the first cable engages with a handle which is associated with the second cable and causes reserve canopy deployment movement of the second cable. Due to the sliding interconnection of the first and second cables, the second cable can be moved independently of the first cable to effect deployment of the reserve canopy without the main canopy being first released.
