The invention relates to a furniture drive for driving a movable piece of furniture, comprising an electric motor, an actuator that can be moved back and forth between two end positions to apply a force on the piece of furniture to be driven, and a gearbox connected between the electric motor and actuator, wherein the gearbox has at least one gear stage configured as an eccentric gearbox and comprising two gear wheels that mesh with each other, wherein one of the two gear wheels is firmly connected or coupled to the actuator and the other gear wheel is coupled to the electric motor such that the eccentric gearbox has two limit positions, which correspond to the end positions of the actuator, and upon a rotation of the gear wheels, starting from the limit positions, the gear ratio decreases over a deformed rotational angle range.
A furniture drive for driving a movable furniture part comprising an electric motor, an actuator reciprocatable between two end positions to apply force to the furniture part to be driven, and a transmission connected between the electric motor and the actuator, wherein the transmission has at least one transmission stage in the form of an eccentric transmission with two mutually meshing gears, characterised in that one of the two gears is fixedly connected or coupled to the actuator and the other gear is coupled to the electric motor so that the eccentric transmission has two end positions corresponding to the end positions of the actuator and the transmission ratio decreases upon a rotation of the gears from the end positions over a defined rotary angle range.
