Abstract

In a tubular reusable and inflatable moulding form of elastic material, which in the inflated state has a substantially egg-shaped cross-section and can be mounted on a groove-shaped sole plate (14), having an external form skin (1) and inner walls (2, 3, 4, 5), which subdivide the inflated moulding form over its entire length into a substantially cylindrical and larger upper hollow space (10), a substantially cylindrical and smaller lower hollow space (12) and two lateral, substantially equal-sized and prismatic hollow spaces (11, 13), the hollow spaces (10, 11, 12, 13) adjoining one another in pairs along the outline of the form cross-section and all hollow spaces (10, 11, 12, 13) forming at least two separate pressure chambers which can each be filled via a valve arranged at one end of the moulding form, it is proposed that of the two substantially cylindrical hollow spaces (10, 12) at least the lower hollow space (12) is designed as a separate pressure chamber inflatable via a valve.
