Abstract
In actuators where an electric motor, via a transmission, drives an activation element intended to cause movement of an adjustable element in the structure in which the actuator is incorporated, particularly within the furniture sector, hospital beds and sickbeds. The level of noise may be reduced in that at least the electric motor ( 6 ) is mounted in tightly fitting recess ( 12 ) in a block ( 11 ) of foam plastics or similar vibration/noise damping material. An additional reduction of vibrations/noise is achieved by inserting a claw coupling ( 9 a, 9 b ) with a gasket of rubber or rubber-like material between the individual claws in the claw coupling.
