Abstract
A rotationally biasing window regulator for controlling the motion of a windowpane, such as a windowpane in a motor vehicle door or door module, comprises a motor or hand crank to produce a force to move the windowpane, drive arm and a sector gear to transmit the force, an attachment assembly attached to the windowpane and a slider assembly slidingly attached to the attachment assembly and mounted over the drive arm, and a counterbalance spring positioned between the attachment assembly and the drive arm placing rotational force on the slider assembly, which directly biases the attachment assembly to force the windowpane in a lateral direction towards a glass run channel. The slider assembly can slide in a stamped metal bracket or in a C-channel. A clip connecting the attachment assembly to the drive arm may be used to releasably secure the regulator in a said position. In alternative preferred embodiment, a pre-assembled door module for installation into a motor vehicle door is provided with a biasing window regulator placing rotational force on a windowpane. The windowpane may optionally be attached to the door module as a complete unit prior to final assembly, and may be installed into the vehicle door through a door module opening below the beltline.
