  • Patent number: 9084481
    Abstract: A piece of furniture has an outer construction (frame), an inner body that can be raised and lowered in relation to the outer construction via a body motor, and a leaf (flap) that is movable via a leaf motor for covering the front face of the raised inner body. The leaf is articulated on the outer construction, and an electronic controller operable by way of at least one operating switch is provided for coordinated actuation of the leaf motor and the body motor.
