Track assembly for sliding vehicle door

A track assembly for a sliding door of a vehicle comprising:

• a roller track positioned adjacent to and above a door sill of the vehicle, said roller track extending between a forward track end and a rear track end;
• said roller track including a sidewall and a lower wall extending away from said sidewall towards the sliding vehicle door, said sidewall and said lower wall defining a roller receiving channel;
• said roller receiving channel defining a roller travel path that extends between said forward track end and said rear track end;
• a roller support arm extending between said roller track and the sliding vehicle door;
• a roller rotatably supported by said roller support arm, said roller having a horizontally extending axis of rotation, said roller disposed within said roller receiving channel for movement along said roller track between said forward track end and said rear track end as the sliding vehicle door is opened and closed, said lower wall of said roller track contacting and supporting said roller as said roller moves along said roller track between said forward track end and said rear track end;
• a wire track extending between a body mount component disposed adjacent said roller track and a track mount assembly that is configured to attach to the vehicle sliding door, said wire track comprising a plurality of interconnected links that allow said wire track to articulate in a wire track articulation plane between a door closed position of said wire track and a door open position of said wire track;
• each of said plurality of interconnected links, said body mount component, and said track mount assembly having a hollow center section cooperatively forming a wire routing cavity;
• a wiring harness disposed in and extending through said wire routing cavity;
• and
• said body mount component being mounted below said lower wall of said roller track such that said wire track articulation plane is disposed below said lower wall of said roller track and such that said wire track is positioned below said roller support arm as said wire track articulates within said wire track articulation plane between said door closed position and said door open position.
