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.
