Abstract
A window vent assist mechanism for use with a vent window operable in a closed position and in a vented position can include a first support configured to connect to a header of a window frame and a second support configured to connect to an upper rail of a window vent disposed in the window frame. The window vent assist mechanism also includes a biasing member disposed between the header of the window frame and the upper rail of the window vent and nearer to an inner side of the vent window and a center of gravity of the window vent. The biasing member is configured to exert a force to urge the window vent to move relative to the window frame to reduce an operating force required to move the window vent to the vented position.
