  • the invention relates to an operating element for a control unit in a motor vehicle with an inner part and a rotatably received around the inner part outer part, wherein between the inner part and the outer part, a sliding bearing is arranged.
  • the rotatable part on the turntable must be stored as free of play and at the same time the turntable must be smooth.
  • a latching device which usually consists of a latching spring and a latching contour, realized in the control, so the ease of movement, backlash and the set detent behavior must ⁇ . be matched.
  • various bearings between a fixed inner part and a rotatable about an inner part arranged outer part have become known.
  • DE 102 12 992 A1 discloses an operating element in which a rolling bearing in the form of a plastic roller bearing is installed between a stationary inner part and an outer part rotatably arranged around the inner part is.
  • the inner part of the operating part assumes the function of the inner ring of the conventional rolling bearing and the handle or the outer part takes over the function of the outer ring of a conventional rolling bearing.
  • the object of the invention is to provide an operating element which, in addition to a backlash-free storage, ensures smooth running and moreover provides a high degree of operating safety.
  • the object of the invention is achieved in that an operating element for a control device is provided in a motor vehicle, in which a lubricant bag is formed on at least one contact surface of the sliding bearing, so that lubricant between the sliding bearing and the contact surface can be brought.
  • a cost-effective solution for a play-free storage is provided with good leadership properties.
  • Conventional standardized plain bearings are on the one hand cost-effective and offer in contrast to rolling bearings the advantage that the outer part is free to play against the receiving part or inner part.
