Furniture drive system

A furniture drive system for a furniture part movably-supported on a furniture carcass, said furniture drive system comprising:

• a mechanical actuating unit including:
• a pivotally mounted actuating arm for moving the movable furniture part,
• a spring device for applying a force to the actuating arm,
• a movably-mounted actuating portion having a transmission opening for transmitting a force from the spring device to the actuating arm,
• an electrical drive unit including:
• an electric motor for the electromotive support of a movement of the movable furniture part,
• an entrainment member configured to be driven by the electric motor for transmitting a torque from the electric motor to the mechanical actuating unit, wherein the entrainment member of the electrical drive unit can be engaged into the transmission opening of the actuating portion,
• wherein the electrical drive unit and the mechanical actuating unit are configured as separate constructional units which can be fixed to one another,
• wherein an abutment surface for the entrainment member is arranged laterally besides the transmission opening, and the entrainment member is pre-stressed by an energy storage member in a direction towards the abutment surface, wherein the entrainment member in a position in which the entrainment member is aligned flush with the transmission opening automatically penetrates into the transmission opening by the force of the energy storage member.
