ABSTRACT:

BACKGROUND OF THE INVENTION
The subject of the present invention is a cursor or runner for supporting a window in a vehicle door window lifter.
Commonly known window runners fit on a guiderail and are driven by a cable. The runner comprises a body and a window connection. The connection is generally a peg passing through a hole in the window and supplemented by a key or “fork” for locking it to the window. The runner peg is introduced through the hole in the window and the key is slipped along that face of the window. The key faces toward the exterior of the vehicle between the end of the peg and the surface of the window to lock the peg in place.
The peg pulls or pushes the window as the latter moves down and up. In this type of connecting system, the locking key is accessible from outside the vehicle. This is not particularly desirable for security reasons.
Other known embodiments for providing the connection between the window and the runner involve passing through the rail in order to lock the window.
It is desirable to provide a window support runner which makes the locking element inaccessible from outside the vehicle. Unauthorized lowering of the window and fraudulent opening of the vehicle door is therefore prevented. It is further desirable to lock and unlock the runner from inside the vehicle without requiring an access opening through the guiderail.
SUMMARY OF THE INVENTION
The present invention provides a clip-in member or clip which elastically clips into a hole in a window to attach a window runner to the window.
A locking member, preferably a screw pre-mounted on the runner, is introduced into the clip from the side of the window which faces toward the interior of the vehicle. The clip preferably includes several flexible tabs arranged around a central passage. The tab ends form catches that press against the edge of the hole in the window when the locking member is inserted.
The locking member is screwed into the elastic clip to securely lock it to the window. The locking member is preferably attached to the side of the window that faces toward the interior of the vehicle thereby being inaccessible from outside the vehicle.
To further retain the clip, the end catches of the flexible tabs lock into the periphery of the hole in the window. It is therefore extremely difficult to detach the clip from the window from outside the vehicle. In consequence, any unauthorized lowering of the window by detaching the window clip-in member is no longer possible.
The present invention provides further advantages. Locking and unlocking can be performed from inside the vehicle without requiring an access opening through the guiderail. Disconnecting does not require passing through the window mounting as the mounting does not pass through a hole in the guiderail. Locking the runner and window connection is quicker as the locking key has been dispensed with.
