Abstract
An electromotive adjustment assembly, includes at least two spindles, each spindle carrying a spindle nut, with both spindle nuts secured against executing a rotation movement. A motor unit is positioned between the spindles and coupled in driving relationship with the spindles for rotating the spindles, whereby the spindles are secured against displacement in longitudinal direction. Connected, directly or indirectly, to the spindle nuts are flexible pull strands which are trained over deflection rollers for attachment with their free ends to profiled lifting members which are secured at an angle to a structure to be adjusted.
