Patent ID: 8317276

Claim:
A furniture drive for driving a movable furniture part, said furniture drive comprising: an electric motor; an actuator configured to reciprocate between two end positions so as to apply force to the furniture part to be driven; and a transmission connected between said electric motor and said actuator, said transmission having a transmission stage comprising an eccentric transmission including two mutually meshing gears, a first one of said two gears being connected to said actuator and a second one of said two gears being coupled to said electric motor so that said eccentric transmission has two end positions corresponding to said end positions of said actuator, and so that a transmission ratio decreases upon a rotation of said two gears from each of said two end positions towards a center position of said eccentric transmission over a defined rotary angle range; wherein axes of rotation of said two gears of said eccentric transmission are arranged at a fixed spacing from each other; and wherein a radius of said second one of said two gears increases starting from each end position over said defined rotary angle range, and a radius of said first one of said two gears correspondingly decreases starting from each end position over said defined rotary angle range.
