The seating part has on its lower side a shell-shaped, downwardly convex seating bowl. The seating part is supported in the vertical direction on a bearing arranged on a head part of the intermediate part that engages the shell-shaped lower side of the seating bowl, and is mounted so as to tilt in all other directions.
