Abstract: A window regulator mechanism comprising an elongated track of generally rectangular channel shape and an elongated rack slidably supported and confined in the track. The track is provided on one side with a continuous slot located opposite the rack teeth to enable a drive pinion to extend through the slot into driving engagement with the rack. A separate connector is assembled with one end of the rack and retained in an assembly relation with the rack by the track structure to thereby enable attachment of the rack to the structure that moves the window between raised and lowered positions.

Abstract: The invention relates to a window regulator comprising a generally flat tape having sufficient flexibility to follow a curved path of substantial radius but being sufficiently rigid to transmit in compression, when guided in a functionally rigid track, sufficient force to regulate a vehicle window, said tape having at one side a series of transversely extending substantially rack shaped teeth, the ends of said teeth being spaced from the edges of said tape to leave flat side guide portions, and a functionally rigid but bendable track comprising a channel having reversely bent guide flanges spaced to receive the toothed portion of said rack.A drive pinion is in mesh with the rack teeth, and preferably the track is curved to present a concavity to the drive pinion.
