Abstract
There is described a shaped object adapted for being connected with a rim at a point located inside the rim well (), having a contact surface () intended to rest on the rim well. It is provided according to the invention that the contact surface () intersects each of a set of mutually parallel first planes () along a curved curve (), which is not merely an arc of a circle and whose distance from a second plane (), that subdivides the contact surface () and that extends perpendicularly to the first planes () increases with a decreasing growth rate, at least in average, at least on one side of the second plane ().
