A release mechanism adapted to release an article from stowage, said mechanism including: an aneroid chamber having a floor surrounded by a chamber wall which terminates in an opening, an elastomeric substantially circular diaphragm having a periphery adapted to contact the chamber wall and to seal the opening to the aneroid chamber, said diaphragm having a portion between the axial centre of the diaphragm and the perimeter of the diaphragm of a lesser thickness than the remainder of the diaphragm to provide a frustum action to the diaphragm to normally maintain the diaphragm in an armed condition. A spigot plate located at and secured to the axial centre of the diaphragm and having a spigot which projects axially from a first face of the diaphragm. A body shackle plate adapted to be located on and secured to the opening of the chamber wall and to sandwich the diaphragm between the body shackle plate and the chamber wall to seal the interior of the chamber from ambient and to form the aneroid chamber, said body shackle plate having a hole through which the spigot of the spigot plate will project when the diaphragm is in an armed condition. A latching mechanism to prevent release of the article from stowage when in an 25 armed condition, and wherein the action of the mechanism is such that when pressure on the first face of the diaphragm is greater than the pressure of air within the aneroid chamber, the diaphragm will flex to retract the spigot of the spigot plate within the spigot hole in the body shackle plate to free to latching mechanism and to allow the article to be released from stowage.
