A guide notch 36, 38 is provided between each pair of nuts 32A, 32B, 34A, 34B. The notches 36, 38 are open downwards and extend parallel to the guide rails in the assembled state (see FIG. 1). In addition, the lower portion 44 of the upper liner 24S is bent outwardly.

The lower liner 241 comprises as complementary final fasteners two nuts 46,48 welded or crimped similar to those of the upper lining. Furthermore, it delimits two recesses 50,52 open upwards.

Referring again to Figures 1 and 2, it is seen that the module 30 includes a window lifter unit 54 and an inner panel 56 of rigid plastic material. The window regulator unit 54. comprises two guide rails 58, 60 extending substantially vertically and parallel to the direction of movement of the pane 18. Each of the guide rails 58, 60 carries, in a conventional manner, a trolley 62.64 slider which supports the window 18. Each of the guide rails 58,60 has, on its lower end, a bracket 66,68 which extends substantially perpendicular to the longitudinal direction of the rail 58,60. The fixing lugs 66,68 are fixed guide rails 58,60 by conventional means, for example by welding.

A cross member 70, which extends substantially horizontally, connected by means of two auxiliary supports 72,74, stirrup-shaped, to the inner sides of the guide rails 58,60. An entraining assembly 76 of the carriages is fixed on the inside of the cross-member 70. This drive assembly 76 comprises a geared motor 78 and coupling means of the geared motor 78 to the carriages 62, 64. The coupling means of the geared motor 78 to the carriages 62, 64 comprise a drum 80 for winding a cable 82 on which is wound a cable 82 which is connected to the carriages 62, 64 by rollers 84, 86, 88, 90 so that classic.

A fitting 91 is fixed to the geared motor 78 in a conventional manner.

A sealing sheet 92 is sealingly arranged between the winding drum 80 and the geared motor 78. This sheet 92 of flexible plastics material, for example polyethylene, is sealed, for example by gluing along its edges. to the inner panel 56. Thus, a dry chamber 94 is formed by the panel 56 and the sheet 92 in which are protected, protected against moisture that eventually enters through the slot 20, the geared motor 78 and its electrical connections (not shown) .

Each of the guide rails 58,60 is fixed at its upper end to a connecting member 96, 97 by a fastening element which is constituted by a first tab 98.

This first lug 98 is fixed via a small cross member 100 to a fastening element of the inner panel and to a fastening element of the module on the lining, constituted by second and third lugs 102, 104.

The three attachment tabs 98, 102, 104 extend substantially vertically.

The inner panel 56 is fixed, at its upper part, on the second tab 102 by a screw 106. The third tab 104 serves to fix the module 30 integrally on the upper lining 24S of the door, by screws 107 which cooperate with nuts 32A, 32B, 34A, 34B.

The small crossbar <B> 100 </ B> extends substantially perpendicular to the surface of the upper liner 24S and guide rails 58,60 and cooperates by interlocking with the corresponding notch 36 formed therein. The small crosspiece 100 and the notch 36 form complementary pre-positioning elements, during module assembly 30, the operation of which will be described below.

Alternatively, the notch 36 may be formed in the connecting member while the small cross member 100, or another male element, is disposed on the upper liner 24S. The sealing sheet 92 is not fixed to the inner panel 56 in the areas of the connecting members 96, 97. On the other hand, it is clamped between the connecting members 96, 97 and the upper lining 24 S of the door. The curved portion 44 of the liner serves to prevent damage and facilitates threading of the sealing sheet 92 during assembly. Additionally, glue can be used in this area to seal.

The lower part of the inner panel 56 has two holes 108 which coincide with holes 110 formed in the lower fastening lugs 66, 68, two guide rails, thus forming final fastening members of the module 30 on the door 10. sealing 92 extends below this attachment point and defines corresponding holes 114 so as to be clamped between the fastening tabs and the inner panel 56, in the mounted state.

The inner panel assembly 56-sealing sheet 92-brackets 68 is secured by two screws 118 cooperating with the welded or crimped nuts 46,48 of the lower liner 241.

The lower ends of the guide rails 58, 60 are received in the mounted state in the recesses 50, 52 of the lower liner 241.

Furthermore, the inner panel 56 has an armrest zone. A handle 124 is arranged in an opening in this armrest 122. This handle 124 is fixed to the fitting 91 integrally with the gearmotor 78 of the window regulator unit by a screw 126.

In addition, an access port 127 is formed in the lower side of the lower liner 241, which can be plugged by a removable cap 128. A trim panel 130 can be snapped by clips <B> 132 </ B> in orifices 134 formed in the upper part of the inner panel 56 to cover the upper liner 24S and the connecting members 96, as is conventional.

The assembly operations of the module 30 according to the invention in the door 10 are very simple.

The module 30 is oriented relative to the door 10 so that the window lifter unit 54 is directed outwardly and the inner panel 56 is directed inwardly. Then, the small cross members 100 of the connecting members 96 are engaged upwardly in the notches 36, 38 of the upper liner 24S, until the small crosspieces 100 abut against the bottom of the notches 36, 38.

Since the module 30 is thus positioned with a small clearance, the lower fastening lugs 66, 68 are applied against the lower liner 241. The low clearance existing at the top makes it possible to align the final fastening holes 108, 110, 114 of the module with the holes. 46.48 of the lower liner 241. The module 30 is fixed rigidly to the lower part by screws <B> 118. </ B> The final fixing of the upper part is performed by the screws 107 which cooperate with the nuts 32A, 32B, 34A, 34B.

Then, the window 18 is inserted into the slot 20 so as to hang it on the carriages 62, 64, as is conventional.

Finally, the trim panel 130 is snap-fastened to the upper liner 24S and the upper portion of the inner panel 56.

It should be noted that, alternatively, it is possible to use a window regulator unit comprising a single guide rail.

It can be seen that the mounting of the module 30 according to the invention is carried out easily and more quickly thanks to the pre-positioning.

The fact that the window regulator unit is rigidly connected to the inner panel also in the unassembled state of the module 30 allows easy handling and storage of the module.
