Glass run guide for slidable vehicle window

A one-piece glass run guide for a slidable vehicle window, comprising an elongate molded polymeric strip having a substantially U-shaped transverse cross section including a base, an inboard leg having a projecting lip portion which engages an interior surface of a slidable vehicle window, an outboard leg having a projecting lip portion which engages an exterior surface of the slidable vehicle window said glass run guide being substantially vertically disposed below a beltline within a vehicle door cavity such that said interior and said exterior surfaces adjacent lateral edges of said slidable vehicle window are substantially continuously engaged by said lip portions below said beltline;

• the surfaces of the lip portions which contact the surfaces of the slidable vehicle window being low friction, non-abrasive surfaces to provide for smooth movement of the window along the guide during raising or lowering of the window;
• the guide being formed of a fiber reinforced polymer having sufficient strength and rigidity to counter forces exerted by the sliding vehicle window to prevent undesirable inboard, outboard, forward and rearward movement of the window;
• and integral mounting means for fastening the guide to a vehicle door frame.
