Abstract
Abstract Stowage and deployment arrangements for parachutes according to which a parachute canopy is first folded and a securing means, forming the deployment device, is wrapped about the folded canopy and secured to itself by detachable pull apart securing means and the parachute suspension lines are reefed outside the device in a manner such that the device will not separate or allow release of the canopy until the suspension lines are fully extended. Novel suspension line reefing arrangements are also described which hold the lines reefed until a pull is exerted on a trigger line from the deployment device.
