Abstract
The invention relates to a drive cartridge comprising an actuating mechanism, in which a spindle can be guided in a hollow cylindrical drive element between two end positions at an axial distance from one another, said positions being defined by the axial length of the drive element, and to a dome-shaped casing that surrounds the drive element in a non-rotatable and non-displaceable manner. The cartridge is characterized in that the drive element has an external contour with an eccentric profile and in that the internal contour of the dome-shaped casing has a positive fit only in those areas of the drive element in which the permissible normal stress exceeds a predefined upper limit.
