ABSTRACT:
A window sliding mechanism such as that which is used in passenger car doors incorporates a system to reduce friction between a window and its respective seal. A channel provided with air holes is fitted along the window edges that ride within a conventional seal. Alternatively, the air holes could be provided in the seal itself. Air is supplied to the air holes by way of a reservoir or small pump attached to the window sliding mechanism. Controlled air flow reduces the friction generated during window travel. In another embodiment, the system to reduce friction is an oscillating device provided to a conventional window sliding mechanism. The oscillating device is powered by a low cost piezo device. The oscillating device would cause the window to vibrate, thereby reducing the friction generated during window travel.
