Abstract
Abstract On a parachute harness, shoulder straps with manually releasable disconnect devices connecting to shrouds of the parachute; each shoulder strap is also connected by a releasable connection which is released by the action of gas under pressure. The chest belt 6 is also made in two parts connected to one another by a separable connection which can be separated either manually or by the introduction of gas pressure; each leg belt of the harness has also parts connected by separable connection either by manipulation or by the introduction of gas pressure; a cartridge container secured on one of the straps or to the harness has a manipulable cartridge piercing device and is connected by suitable flexible conduits to all the separable connections so that when the piercing device is manipulated and pierces the cartridge, the escaping gas under pressure is quickly conducted to all the severable connections and quickly releases all the harness straps and belts so that the person can quickly divest himself of the parachute harness by a single manipulation.
