Window regulator having a cam member for lateral adjustment

A motor vehicle window regulator mechanism for moving a window glass upwardly and downwardly with respect to a vehicle door, the window regulator mechanism comprising:

• first and second spaced vertical guide rails;
• first and second carrier plates respectively slidably mounted on the first and second rails;
• first and second glass clips slidably mounted on an upper edge of a respective one of said first and second carrier plates and adapted to fixedly receive a lower edge of the window glass;
• and
• a cam member journaled on the first carrier plate for rotation about an axis of rotation and having a geometric center that deviates from the axis of rotation wherein rotation of said cam member about said axis of rotation causes circumferentially spaced peripheral points on the cam member in association with a generally U-shaped coacting surface on the first glass clip to move the first glass clip laterally with respect to the guide rails.

A motor vehicle window regulator mechanism for moving a window glass upwardly and downwardly with respect to a vehicle door, the regulator mechanism including first and second spaced vertical guide rails, first and second carrier plate structures slidably mounted on a respective one of said first and second guide rails, drive means for moving the carrier plate structures upwardly and downwardly on the guide rails, and first and second glass clips carried by a respective one of said first and second carrier plate structures and adapted to receive a lower edge of the window glass whereby to raise and lower the window glass in response to upward and downward movement of the carrier plate structures, characterized in that:

• the regulator mechanism further includes a rotary cam member mounted for rotation on the first carrier plate structure, and a coacting surface defined on the first glass clip;
• the cam member and coacting surface coact in response to rotation of the cam member to move the first glass clip laterally with respect to the first carrier plate structure;
• the first carrier plate structure includes a carrier plate;
• the first glass clip defines an upwardly opening groove for receiving the lower edge of the window glass and a downwardly opening groove for receiving an upper edge of the carrier plate;
• the upwardly opening groove is defined by a main body portion of the first glass clip and the downwardly opening groove is defined by a surface of the main body portion and a stabilizer portion extending downwardly and in parallel relation to the main body portion surface;
• and
• the coacting surface is defined on the stabilizer portion.

A motor vehicle window regulator mechanism for moving a window glass upwardly and downwardly with respect to a vehicle door, the window regulator mechanism comprising:

• first and second spaced vertical guide rails;
• first and second carrier plates respectively slidably mounted on the first and second rails;
• first and second glass clips slidably mounted on an upper edge of a respective carrier plate and adapted to fixedly receive a lower edge of the window glass;
• and
• a cam member including a circular cam portion received in a cutout in the first glass clip and a journal portion rotatably mounted on the first carrier plate and offset from a geometric center of the cam portion wherein rotation of said cam portion causes circumferentially spaced peripheral points on the cam portion in association with a coacting surface on the first glass clip to move the first glass clip laterally with respect to the guide rails;
• each clip defining an upwardly opening groove for receiving the lower edge of the window glass and a downwardly opening groove for receiving the upper edge of the respective carrier plate;
• the upwardly opening groove of each clip being defined by a main body portion of the clip and the downwardly opening groove of each clip being by a surface of the main body portion and a stabilizer portion extending downwardly in spaced parallel relation to the main body portion surface;
• and
• the cutout receiving the cam portion of the cam member being constituted by a cutout in a lower edge of the stabilizer portion of the first clip.
