A regulator assembly for moving a window panel between its open and closed positions, suitable in certain preferred embodiments for operation of motor vehicle windows for example, has drive mechanism such as a hand crank or electric motor for delivering a drive force to the regulator assembly to move the window panel. Linkage, including at least a lifting arm and, optionally, a cross-arm, etc., is connected to the window panel at one end and mounts at its other end a sector gear engaging the drive mechanism. Load absorbers are provided for releasably absorbing drive force upon operation of the regulator assembly between any two points of travel of the window panel between the open and closed positions. The load absorbers help to level the peak loads otherwise experienced by the regulator assembly and, particularly, an electric drive motor thereof, during start-up and travel stall at the full open position, full closed position, intrusion or blockage during closure travel.
