Motion translating mechanism for use as a window regulator or the like

摘要

A mechanism particularly well suited for converting bidirectional rotation, as of a reversible electric motor or a hand crank, into the linear up and down motion of a windowpane relative to the frame of a passenger car door. Included is an elongate guide rail gently curved longitudinally to conform to the vertical curvature of the vehicular door and providing a vertical guideway on its convex side. A wire rope or cable is looped about a pair of terminal guide pulleys or nonrotatable guides on the opposite ends of the guide rail. One of the two stretches of the cable is coupled to a windowpane carriage which is coupled to the windowpane for joint up and down movement therewith along the guideway. A drive mechanism including a drive reel is mounted to the guide rail and coupled to the other stretch of the cable for bidirectionally driving the windowpane carriage along the guideway. The drive mechanism is compactly disposed on the concave side of the guide rail for minimal space requirement.
