Abstract
An altitude protection device for an acceleration protection suit having a plurality of liquid-filled veins is comprised of a bladder inserted in a pocket. A spacer fabric that is non-compressible under the loads to be provided is enclosed in the pocket and defines a minimum volume inside the bladder. The bladder is closed off or opened relative to surrounding air in the aircraft cabin via a valve that is opened if a rate of pressure change in the cabin is less than or equal to a presettable maximum value, and closed if the rate of pressure change is greater than the value. If the valve closes and the pressure falls further, air located in the bladder inflates the bladder and pocket, increasing tensile stress in the fabric, and thereby raising the internal pressure of the veins resulting in increased internal pressure in the entire acceleration protection suit.
