Abstract

The linear drive for a motor vehicle has a non-self limiting threaded spindle (20) rotatable in either direction. A drive clutch has a control switch (42) to release the drive when the spindle reaches an end position. The clutch has a coil spring (54) which is released into a bush (56) and allows a movement of the threaded spindle in dependence on the fine adjustment of the switch. Claims include a drive method using the claimed drive.
