Sliding member for power window devices in motor vehicles

1- Sliding member (1) for power window devices in motor vehicles adapted for being moved along a guide rail (2) including, at least at one of their ends, one end stop member (3) for said sliding member (1), said sliding member (1) being associated with the lower edge (4a) of a window pane (4) of the motor vehicle and being provided with means for adjusting its relative position, characterized in that said means for adjusting the position of the sliding member (1) comprise:

• a transverse adjustment threaded element (5) that is transversely received into the sliding member (1) within a threaded hole thereof which inner end (6) acts on a resilient inner surface (7) of the sliding member (1) causing the position of the window pane (4) to be adjusted in one substantially perpendicular direction (Y) thereto producing a slight pivoting movement of said window pane (4);
• a fastening screw (11) transversely inserted into the sliding member (1) within a further hole thereof passing through a slot in the window pane (4) and inserted into the sliding member (1) allowing the position of said window pane (4) to be adjusted in one substantially horizontal direction (X), and
• at least one vertical adjustment threaded element (12;
• 12a) that is threadingly received into a body formed integrally with the sliding member (1), the free end (13;
• 13a) of said threaded element (12;
• 12a) abutting said end stop member (3) of the rail (2), allowing the window pane (4) to be adjusted in one substantially vertical direction (Z).
