Acceleration protective suit

A suit for protection of a wearer against acceleration forces comprising:

• an active part that includes at least one double-walled portion filled with a fluid, which, in response to accelerations * 1 g in a momentary and local z-axis, builds up a compensating outer force corresponding to an internal force on the wearer, the suit comprising at least in part an inner layer and an outer layer of a fluid-tight and low stretch textile material, the layers being joined together at connection positions such that hollow spaces arise between the connection positions, wherein the hollow spaces form a continuous hydrostatic pressure column from ankles up to a neck of the wearer, the inner layer exerting a pressure on the body of the wearer corresponding to a height of a fluid column and an effective acceleration in the momentary and local z-axis, a tensile force being built up in the outer layer in response to the pressure, wherein the connection positions are adapted to be joined to single layer connecting pieces, the single layer connection pieces comprising low stretch textile material outside the hollow spaces, which are adapted to transmit the tensile force built up onto the surface of the body of the wearer of the suit, the connection positions being arranged such that shortening of separation of neighboring connection positions in response to the pressure of the fluid present in the hollow spaces causes a build up of an intended tensile force in direction and magnitude and transmission of the intended tensile force to neighboring elements, wherein the active part of the suit includes means for matching the suit to current bodily conditions of the wearer and means for closure that are simultaneously suited for building up a necessary basic pressure of the suit for straight flight;
• and
• a cushion comprising at least one layer, wherein:
• each of the at least one layer is individually fluid and airtight sealed and comprises an open-pored plastics material foam, each of the at least one layer having a connection that is adapted to be optionally connected to at least one tensioning element or to the hollow spaces;
• the cushion is between the body of the wearer and a seating surface of a pilot's seat and is adapted to be optionally fastened to the suit or to the pilot's seat;
• the at least one layer of the cushion is adapted to be filled either with air or a fluid;
• and
• the cushion exerts, in the presence of accelerations>1 g, an additional pressure on fluid or gas bearing parts of the suit.
