Abstract
The invention relates to continuously variable manual drives for seat adjusters in motor vehicles. In a first design of the invention the drive has a transmission step which is coupled on the drive side or output side to the drive. A second design of the invention provides a continuously variable manual drive for seat adjusters in motor vehicles in which the drive and the output-side gear elements are connected together through a switchable coupling device, which in the non-actuated state maintains the power flow between the drive and the output-side gear elements by means of spring pretension and in the actuated state breaks off the connection between the drive and the output-side gear elements so that a passive seat adjustment is possible.
