Abstract (en)
[origin: WO9500381A1] The elastic membrane described is designed as a flat, three-dimensional object. It has prominences and recesses. This makes it possible for the membrane to flex substantially free of stress, in particularly free of tensile stress, in all three dimensions simultaneously. Prior art elastic membranes of this kind suffer from the disadvantage that they cannot flex substantially free of stress, in particularly free of tensile stress, in all three dimensions and cannot therefore meet certain requirements.
