Abstract (en)
[origin: US5562042A] PCT No. PCT/CH94/00094 Sec. 371 Date Mar. 23, 1995 Sec. 102(e) Date Mar. 23, 1995 PCT Filed May 24, 1994 PCT Pub. No. WO95/00381 PCT Pub. Date Jan. 5, 1995The elastic membrane is designed as a flat, three-dimensional object. It has prominences and depressions. This makes possible a deformation which is substantially free of stress, in particular free of tensile stress, simultaneously in all three dimensions. The elastic membranes of this type which are known today suffer from the disadvantage that they are not substantially free of stress, and in particular free of tensile stress, in all three dimensions and therefore cannot meet certain requirements.
