ABSTRACT:

BACKGROUND OF THE INVENTION
The present invention relates to a device for supporting a window in a vehicle door window lifter, comprising at least one clamp with two jaws for gripping the window, these jaws being designed to grip the lower edge of the window, a back plate laterally extending from one jaw approximately in the plane thereof, a slider which is shaped so that it can slide on a window lifter guide rail, and means for securing the slider and the back plate.
SUMMARY OF THE INVENTION
In a preferred embodiment, the window lifter comprises two guide rails, each having one window support device associated with it.
The object of the invention is to provide a window support device in which it is easy to assemble the back plate and the slider and which takes up a small amount of space in the transverse direction.
According to the invention, the window support device is characterized in that formed in the slider is a recess designed to receive the back plate, and in that the back plate has lateral tabs designed to slide as far as an abutment position along retaining ramps in the slider formed to the side of the recess, and in that means are provided for locking the back plate in its position in abutment on the slider.
The back plate and the slider are therefore assembled by first pushing the back plate into its initial position on the slider, then by making it slide in the recess of this slider until its lateral tabs, sliding under the attachment ramps of the slider, come into abutment.
According to one embodiment of the invention, the slider has a central aperture in which there is a member for locking the back plate, the edges of the recess are each provided with at least one ramp under which an associated tab of the back plate can engage and slide, and this ramp is extended by a transverse end stop for the tab.
Other features and advantages of the invention will appear during the description given below, made with reference to the appended drawings which illustrate two embodiments thereof by way of non-limiting example.
