Bottom drive rail-less window regulator

A side door having a window moveable between opened and closed positions and at least one door panel, the side door comprising:

• a window having a front edge, a rear edge, a top edge, and a bottom edge;
• a front window run channel attached to a door panel in which the front window edge may reversibly move;
• a rear window run channel attached to the door panel in which the rear window edge may reversibly move;
• and
• a window regulator assembly comprising:
• a window bracket in contact with the bottom edge of the window;
• a cable assembly having first and second ends;
• a carrier plate in contact with the window bracket and both ends of the cable assembly;
• the carrier plate comprising a self-guiding pocket and a tension clip having a first side and a second side;
• a tension spring located on at least one end of the cable assembly to provide a predetermined amount of tension to the cable assembly, thereby, generating a load force;
• an upper bracket assembly capable of slideably receiving the cable assembly;
• a drum housing having a cable drum capable of slideably receiving the cable assembly the cable assembly;
• a hollow conduit located between the upper bracket assembly and the drum housing that can slideably receive the cable assembly;
• and
• a drive unit for rotating the cable drum;
• wherein the load force generated upon applying tension to the cable assembly is borne between the cable drum and the upper bracket assembly by a compression force placed upon the conduit;
• wherein the second side of the tension clip compresses the tension springs located on each end of the cable when the carrier plate and window bracket are separated;
• wherein the interaction between the window regulator assembly, the window run channels, and window moves the window between open and closed positions.

A rail-less, bottom drive window regulator assembly for moving a window having a front, rear, top, and bottom edge between opened and closed positions in a vehicle door having at least one door panel with front and rear window run channels in which the front and rear window edges may vertically move, the rail-less, bottom drive window regulator assembly comprising:

• a window bracket in contact with the bottom edge of the window;
• a cable assembly capable of generating a load force when tensioned;
• an upper bracket assembly capable of slideably receiving the cable assembly;
• the upper bracket assembly being attached proximate to the top of the door panel;
• a drum housing having a cable drum capable of slideably receiving the cable assembly and a drive unit for rotating the cable drum;
• the drum housing being attached proximate to the bottom of the door panel and aligned with the upper bracket assembly in order to allow the window to move in a vertical direction;
• and
• a curved, hollow conduit attached to the upper bracket assembly and the drum housing capable of slideably receiving the cable assembly;
• wherein the load force generated upon applying tension to the cable assembly is borne between the cable drum and the upper bracket assembly by a compression force placed upon the conduit such that the conduit prevents deformation of the door panel;
• wherein the drum housing remains below the window when the interaction between the window regulator assembly, the window run channels, and window moves the window between the open and closed positions.
