  • Patent number: 10470563
    Abstract: A height-adjustable piece of furniture includes a lower part, an upper part, an actuating device, first and second reference sections and a deformation sensor. Distance between the lower and upper parts can be adjusted by the actuating device. The deformation sensor is arranged to detect change between the first and second reference sections and is connected to the actuating device such that a signal of the deformation sensor can be transmitted to the actuating device. The actuating device is configured to stop the change in distance between the lower and upper parts if the signal transmitted by the deformation sensor corresponds to a change in distance that exceeds predefined threshold values. A cable protector is also provided for a cable to be mounted, and is coupled to the first and second reference sections such that tensile force acting on the cable causes change between the first and second reference sections.
