US Patent 6979962 Internally suspended motor for powered window covering

A metal or plastic tube is formed with slots to establish a noise dampening coupling to isolate the head rail of a window covering from vibrations from a motor in the head rail. The noise dampening coupling can be coupled to the output gear of the motor and to an actuator in the head rail to couple the motor to the actuator while isolating the head rail from vibrations. Also, a non-rotatable noise dampening coupling can be interposed between the motor and head rail to further isolate the head rail from vibrations.
