Abstract: An oxygen generator of an emergency chemical oxygen generating system is mounted on a sliding mechanism that displaces the oxygen generator vertically and horizontally away from the walls of the oxygen generator container when the door of the module is opened, in order to reduce the heating of the container walls and the surrounding areas. The sliding mechanism can be a telescoping assembly having multiple sliding segments, a slot in the side of the module wall with a tab attached to the generator such that the tab slides within the slot allowing for downward sliding of the generator, or an arrangement of channels and rollers. The movement of the generator from a stowed position to a use position can also initiate the flow of oxygen.
