Abstract
An electric linear drive, in particular for adjusting moveably mounted parts of furniture used for sitting or lying down, includes a drive motor, a threaded spindle, a speed reduction gear arranged between the drive motor and the threaded spindle, a spindle nut placed on the threaded spindle, which can be selectively locked in the direction of rotation and, depending on the direction of rotation of the threaded spindle, moved in the axial direction of the threaded spindle. The linear drive has a lifting element for adjusting the moveable furniture parts, the lifting element being driven by axial movement of the spindle nut. Simple design, easy assembly and operation, and robust mounting of the driving parts are achieved.
