The present invention relates to a rotary drive (100) comprising: an output shaft (330); a motor (20), acting on the output shaft (330) via a downstream gear mechanism (30); an energy-store module with a linear line of action and with transmission elements (32, 326) to apply pressure circumferentially to an eccentric cam disk (331) arranged on the output shaft (330) for conjoint rotation therewith; and an intermediate shaft (320), being offset in relation said line of action and being provided between the motor (20) and the output shaft (330). The transmission elements (32, 326) comprise a roller lever (32), having a cam-follower roller (326) spaced apart from the intermediate shaft (320), wherein the cam-follower roller (326), pressed circumferentially against the eccentric cam disk (331), interacts with the output shaft (330). The energy-store module is arranged on the motor side in relation to the intermediate shaft (320).

A furniture drive system includes a mechanical control unit having a pivotably mounted control arm for moving a movable furniture part, a spring device for applying force to the control arm, and a movably mounted control part having a transmission opening for transmitting a force from the spring device to the control arm. An electrical drive unit has an electric motor for moving the movable furniture part, and a driver to be driven by the electric motor for transmitting a torque of the electric motor to the mechanical control unit. The driver can be inserted into the transmission opening, and the electrical drive unit and the mechanical control unit are designed as separate assemblies and can be fastened to each other. A contact surface for the driver is arranged laterally adjacent to the transmission opening and the driver is preloaded toward the contact surface by a force store.

An assembly for moving a door of a piece of furniture, the assembly being adapted to move between a retracted configuration and an extended configuration so as to drive the door respectively between a closing position and an opening position. In particular, the assembly comprises a first arm adapted to be rotatably coupled with a first end to the side around a first rotational axis, a second arm articulated with a first end to a second end of the first arm around a second rotational axis, a third arm articulated to a second end of the second arm around a third rotational axis, the third arm being able to be attached to the door, and guiding means for guiding the roto-translatory motion of the door between the closing position and the opening position.

An apparatus for opening and closing a deck lid of a vehicle body includes a jack-screw type drive unit having two elongated relatively rotatable drive elements which are threadably engaged for bi-directional displacement. An electric motor engages the rotatable drive element. A first mounting device pivotally connects the rotatable drive element to a relatively fixed point on the vehicle. A second mounting device pivotally connects the non-rotatable drive element to the deck lid, or vice versa. The motor is energized to affect bi-directional control of the drive unit while enabling low back-drive effort. A concentric spring counters loading due to the weight of the deck lid.
