Abstract

An electromotive linear drive, in particular for adjusting movably mounted parts of lounging and seating furniture, has a drive motor, a threaded spindle, a speed-reducing gear unit arranged between the drive motor and the threaded spindle, and a spindle nut () located on the threaded spindle. The spindle nut is optionally lockable in the direction of rotation and movable in the axial direction of the threaded spindle, depending on the direction of rotation of the threaded spindle. A lifting element can be driven by the axial movement of the spindle nut to adjust the movable furniture parts. Such a linear drive has a simple design, is easy to assemble and operate, and guarantee a robust mounting arrangement for the drive parts.
