Apparatus for assembly of a window on a window regulator

A system comprising:

• a mobile element;
• an adapter element fixed to the mobile element, said adapter element including a first substantially vertical extension coplanar with the mobile element, a second substantially horizontal extension extending generally perpendicularly away from said first extension in a longitudinal direction of the mobile element, and at least said first extension having a plurality of adapter teeth;
• a slider element guided by at least one rail secured to a vehicle door and driven by a drive device, and said slider element includes a third extension extending in the longitudinal direction of the mobile element, at least one guide block guided along said at least one rail, and a vertical wall defining a first contact surface, and said second extension of the adapter element cooperates with the third extension of the slider element to allow slight relative movement between the adapter element and the slider element under the action of a longitudinal force applied to the mobile element before fixation of the slider element to the adapter element;
• a confining element that defines a second contact surface, and the adapter element is held between the slider element and the confining element, and at least one of the first contact surface and the second contact surface has a plurality of confining teeth that are substantially parallel to the plurality of adapter teeth and that cooperate with the plurality of adapter teeth;
• and
• a fixation member extending through and connecting the adapter element, the slider element and the confining element, and the fixation member cooperates with the confining element to secure the first extension of the adapter element between the first contact surface of the slider element and the second contact surface of the confining element by urging the adapter teeth and containing teeth to interengage.
