  • Power sliding window assembly
    Patent number: 5669181
    Abstract: A power window assembly in a vehicle includes first and second slidable window panes mounted to the vehicle for movement in opposing lateral directions towards each other to a closed position and away from each other to an open position. A first pair of connector arms is operatively connected to the first window pane and a second pair of connector arms is operatively connected to the second window pane. A power drive mechanism engages the connector arms and selectively pulls one of the connector arms of the first pair and one of the connector arms of the second pair away from each other to pull the window panes towards the open position and selectively pulls the other of the connector arms of the first pair and the other of the connector arms of the second pair towards each other for pulling the window panes towards the closed position.
