In other words, it is conceivable that the curvatures differ from each other only in terms of their sign and otherwise have the same shape or the same course. Furthermore, it is conceivable that the curvatures have the same sign and differ from each other in terms of their course or in terms of their shape. Further, it is conceivable that the curvatures sow ohl differ in terms of their sign as well as in terms of their shape or their course respec- tion from each other.
- the tube elements are further provided such that the free ends, in particular first, are spaced apart from one another.

- the respective pliable Mate rial is aligned and arranged such that the fibers of the pliable Mate rials are arranged at an angle of 45 ° + - 20 ° to the longitudinal direction.
- a particularly advantageous torsional stiffness can be realized.
- the generation of wrinkles can be prevented particularly g ut, since the material can stretch in corresponding directions.
- this fiber orientation a particularly advantageous formability, so that the rocker can be made particularly well.
- the volume device to reali it is preferably provided that the shell is formed, for example, from a limp in itself and preferably airtight and / or inelastic Mat erial.
- the tubes 1 - 8 form, for example, respective first chambers, which can be inflated by the aforementioned gas in the first chambers (tubes 1-8) introduced, in particular blown, is.
- the volume element 10 has at least one first connection via which the gas can be introduced or introduced into the tubes 1 -8 (first chambers).
- the volume element 10 delimits, for example, at least partially a second chamber, which is partially bounded by the volume element 110 and partially by the casing.
- the second chamber is thus arranged between the volume element 10 and the casing, which is also referred to as casing.
- granular matter is preferably arranged in the second chamber.
- the second chamber evakuierba r.
- the volume device has at least one second connection via which the second chamber can be evacuated. This is to be understood as meaning that a gas initially taken up in the second chamber, for example air, can be removed at least partially, in particular at least predominantly, from the second chamber.
- Fig. 3 shows a second embodiment of the procedural rule, in which the tube elements 12 and 14 are provided, for example, as Baueinh eit, wherein the respective tube 1 -8 each have exactly one free s end 32 and 34 respectively.
- the first and second embodiments exactly two tube elements 12 and 14 are provided, the number of tubes 1-8 being greater than the number of tube elements 12 and 14.
- 4 shows a third embodiment of the method in which three tube elements 12, 14 and 15 are provided.
- the tube member 14 and its tubes 1 and 5 have no free ends, however, the tube member 14, the Rö listen 6, 7 and 8 with the free ends 30 and 34, respectively.
- a first of the seams 16a of the tubular member 12 having the different curvatures is the seam 16a of the tubular member 12.
- the second of the directly adjacent seams is the seam 38 of the tubular member 14 disposed between the tubular members 12 and 15 .
- the tubes 1 and 5 of Röhreneleme nts 14 are formed by seams 44 and 46 and by the seam 38, wherein furthermore the seams 18 a and 46 are immediately adjacent seams, which have different curvatures from each other at least in respec gene lengths.
- the first free ends 28 and 30 or 32 and 34 of the tube elements 12, 14 and 15 are moved towards each other.
- Fig. 5 shows a fourth embodiment of the procedural rens, wherein the fourth embodiment with respect to the arrangement and in particular special orientation of the tube elements 12 and 14 to each other from the previously described embodiments b.
- Fig. 6 shows a fifth embodiment of the method wherein the tube members 12 and 14 are provided such that the immediately adjacent sutures 36 and 38 are spaced apart from each other over their respective full extent.
- Fig. 7 shows a sec tion hste embodiment, in which the immediately adjacent seams are the seams 16 d and d 18 d. However, as described with respect to the first embodiment, the tubular members 12 and 14 are connected to each other via the sides on which the seams 36 and 38 are arranged. Further, Fig.
- Sehl warelich Fig. 9 shows an eighth embodiment of the method in which the immovable adjacent seams are the seams 36 and 18 d, wherein - as already described for the first and sixth embodiments - the tube elements 12 and 14 via the seams 36 and 38 and are connected to each other via the sides on which the seams 36 and 38 are arranged.
