Inflation piece, has inflatable sheath fixed at outer edge of base by mounting device, and pump and rotary drive component produces rotating movement of base against fixed plate within sheath and mounted in plate in fixed manner

摘要

The piece has a three-dimensional sheath (3) fixed at a socket element (2), and a predominant gas-proof material arranged in the element in a form of a ball by a pump. An inner base (5) includes a circular outline with a central through hole (8), where the base is arranged directly over a base plate (4). An inflatable sheath (1) is fixed at an outer edge of the base by a mounting device (7). The pump and a rotary drive component (22) produces a rotating movement of the base against the fixed plate within the sheath (30), and are mounted in the plate in a fixed manner.
