an upper guide rail attachment mounted at an upper portion of a guide rail and a lower guide rail attachment mounted at lower portion of the guide rail, whereby the lower guide rail attachment is configured to tilt the guide rail and a glass, whereby the lower guide rail attachment comprises a guide rail bracket and a window regulator bracket are mounted on a door inner panel, a cam plate is sandwiched between the guide rail bracket and the window regulator bracket;
the guide rail bracket is configured with a guide rail bracket slot and a stud bolt, the window regulator bracket is configured with a window regulator bracket slot and a camshaft hole, the guide rail bracket slot is aligned with the camshaft hole of the window regulator bracket, and the stud bolt of the guide rail bracket is aligned with the window regulator bracket slot;
the cam plate is configured with an anti-rotation hole and a cam plate slot, whereby the anti-rotation hole of the cam plate is aligned with the guide rail bracket slot and the camshaft hole of the window regulator bracket, and the cam plate slot is aligned with the stud bolt of the guide rail bracket and the window regulator bracket slot;
the stud bolt of the guide rail bracket is configured to connect the guide rail bracket and the window regulator bracket by introducing the stud bolt through the cam plate slot and the window regulator bracket slot;
a camshaft is configured to connect the window regulator bracket and the cam plate by introducing the camshaft through the camshaft hole of the window regulator bracket and the anti-rotation hole of the cam plate, whereby the camshaft rotation enables the stud bolt to move within the window regulator bracket slot, the rotary motion of the camshaft is transmitted to the stud bolt via the cam plate, enabling the guide rail bracket to move along the slot of the window regulator bracket, thereby tilting the guide rail and the glass via the window regulator adjustment assembly.
