Sliding window for use in pick-up truck rear window assembly

A rear window assembly for a pick-up truck, comprising:

• first and second fixed window panels;
• a slidable window panel located between and approximately flush with the first and second fixed window panels when in a closed position;
• at least upper and lower elongated tracks for enabling the slidable window panel to slide from the closed position to an open position, and vice versa;
• a pivot member attached to the slidable window panel via at least one support, the pivot member sliding in one of the elongated tracks during opening and closing of the slidable window;
• and
• a spring applying a biasing force to the pivot member so that the slidable window is biased toward a position where it is approximately flush with the first and second fixed window panels.

A rear window assembly for a pick-up truck, comprising:

• first and second fixed window panels;
• a slidable window panel located between and approximately flush with the first and second fixed window panels when in a closed position;
• and
• means for biasing the slidable window panel toward the closed position where it is approximately flush with the first and second fixed window panels, the means for biasing comprising a spring for biasing a pivoting member that is operatively associated with the slidable window panel.

A rear window assembly for a pick-up truck, comprising:

• first and second fixed window panels;
• a slidable window panel located between and approximately flush with the first and second fixed window panels when in a closed position;
• and
• a power system for laterally moving the slidable window panel during opening and closing of the slidable window, the power system comprising an elongated screw on which at least one threaded collar is threadedly mounted, said at least one collar being attached to the slidable window panel via at least a pivoting link member pivotally associated with the collar and a bracket having a channel defined therein for slidingly receiving a sliding member attached to the link so that during opening of the slidable window panel rotation of the screw causes the collar, the link, the sliding member and the slidable window panel to move laterally.
