Abstract
A quiet motorized window shade assembly mountable within a window frame includes a flexible shade and an elongated roller. An end of the shade is retained on the roller for winding of the shade on the roller. The window shade assembly further includes a drive system located externally of the roller. The drive system includes a motor and a drive shaft having a central axis parallel to a central axis of the roller. The drive shaft is connected to an acoustically lossy drive belt supported by drive and roller pulleys to transfer rotation of the drive shaft to rotation of the roller. The roller and drive belt substantially span a distance that separates opposing surfaces of the window frame to provide minimal distances between the window frame and the shade.
