Abstract: A window assembly is mounted in a socket window opening of a motor vehicle with the interior side of the window frame substantially coplanar with the body flange in the window opening and the exterior side of the assembly. The window assembly is secured in place by means of self-tapping screws or other fasteners that extend through perforations in the window frame in the body flange into the window frame. In the best embodiment of the invention a stationary window and a sliding window are mounted wholly within the space forming the socket and substantially the entire window frame is also mounted within the socket.

Abstract: A panel in the form of a movable window frame hinged along its upper edge is swung from a closed position to an open position by a mechanism which includes a torque rod and crank-operated self-locking gearing to actuate the torque rod. A vibration damper in the form of a friction pad or brake shoe that engages the torque rod at a distance from the gearing, prevents chattering of the window when it is being swung towards its closed position and also resists any tendency for wind or vibration to oscillate the window.
