Abstract:
1. A pneumatic component comprising: an airtight elongated hollow body made from flexible material, the hollow body being capable of being charged with compressed air; at least one compression member extending along a surface line of the hollow body and adjacent thereto for protection against displacement and bending; at least one pair of tractive elements secured at opposite ends of the at least one compression member wherein the at least one compression member is furnished at opposite ends thereof with a node for reciprocal, non-positive attachment of the at least one compression member and the at least one pair of tractive elements for absorbing bearing forces; wherein the at least one pair of tractive elements are arranged so as to wind round the hollow body at least once and in opposite directions and cross each other on the surface line of the hollow body opposite to the at least one compression member; and wherein means are integrated for electrically altering at least one of the operating parameters pressure in the hollow body, length of the compression member, or length of the tractive elements.
