Claim Text:
1. An electromotive furniture drive for adjusting movable furniture components relative to one another, comprising: a power supply device constructed as a switched-mode power supply unit and configured for assuming a “disconnection” operating state and an “operation” operating state, said power supply device including a mains connection for connection to a mains, wherein the power supply device is configured to transform an input voltage on a mains side into a low voltage on an output side, said power supply device further comprising an isolating transformer or a transformer unit for electrical isolation between the mains-connected input side and the low-voltage-supplying output side for operation of the electromotive furniture drive, an intermediate circuit, a control device for controlling the switched-mode power supply unit, a control supply unit associated with the control device, and a controllable disconnecting unit; a manual control operably connected to the controllable disconnecting unit via a control line and having a switching contact for changing an electric control signal of the control line, wherein in response to a change of the control signal said disconnecting unit causes the control device to directly switch the power supply device to the operating state of “disconnection” in a non-actuated state of the manual control; at least one electric motor configured for operation in opposite directions of rotation; a speed reduction gear arranged downstream of the electric motor; and a gear arranged downstream of the speed reduction gear.
