Abstract
The invention relates to an electromotive furniture drive comprising a drive motor (10). The drive motor (10) has a driveshaft (11) which is mechanically coupled to a brake device (13), and the brake device (13) has a looping wrap spring (15). The electromotive furniture drive is characterized in that the brake device (13) comprises a brake element (17) which is designed to apply a braking torque to the drive shaft (11) in a rotational direction. The brake element (17) is operatively connected to a coupling element (16) in a mechanical manner, and the wrap spring (15) is positioned on an outer lateral surface (161) of the coupling element (16).
