The invention relates to a method for inserting or glazing panes in motor vehicle bodies.

It is already known to glaze in motor vehicle windows, in particular made of laminated glass, with the help of a rubber profile, where optionally between rubber and glass as well as between rubber and body flange additionally liquid adhesive sealants to increase the tightness and the pane composite. It is also already known a direct connection of windshield and body with the help of permanently plastic, strongly adhesive profiles or with help of pasty, sprayable, moisture-reacting, one or produce multicomponent masses, which after the introduction or after the mixing of the individual components to a permanently elastic Cross-link material.

Glazing with the help of a rubber profile, which has been widely used up to now, provides connection strengths that meet safety regulations are not sufficient, as they already apply in the USA today. The additional use of adhesive sealants for Fulfilling such requirements is technically complex and problematic with regard to the result achieved.

A disadvantage of the direct connection of wheel / body by means of permanently plastic, strongly adhesive profile is that the strength of the compound is normally prepared on the basis of butyl rubber has considerable variations in the occurring in practice the temperature range of -3O ° C to 8O ⁰ C. For example, there is a risk of a reduction in performance due to the so-called "cold flow" of the sealing compound under constant stress. To avoid such a reduction in performance, additional technical installation support measures must therefore be taken, depending on the structural conditions. Furthermore, there is insufficient resilience.

A major disadvantage of the connection of the windshield / body by means of pasty, due to air humidity to one elastic vulcanizate-like material of crosslinking one-component masses, which are based, for example, on polyurethanes, silicones or polysulfides, is special Effort when adding the compound, depending on the hardening process on the ambient temperature, from the relative humidity as well as from technical installation measures when inserting the pane up to the moment self-supporting, in the considerable cleaning effort during assembly as well as in the difficulty of changing the panes after the polymer has cured. The procedure

is therefore unfriendly to repair and customer service and involves a not inconsiderable risk because the application conditions for the sealants may change after a long period of storage.

The direct connection of windshield and body with the help of pasty, sprayable, two- or multi-component compounds, which cross-link after mixing the individual components to form an elastic, vulcanizate-like mass and, for example based on polysulfide or polyurethane, is due to the large equipment required for mixing and Bringing in the masses is disadvantageous. In addition, this method requires a great deal of control effort in the preparation of the mixture in order to detect incorrect mixtures, for example through a A shift in the mixing ratio or the pot life can be ruled out. Further disadvantages of this known method lie in the technical installation measures when inserting the pane until it is self-supporting the considerable cleaning effort during assembly, the poor interchangeability of the panes and his Repair and customer service unfriendliness.

In contrast, the object of the invention is to create an improved method for glazing motor vehicles, in which the disc can be quickly installed and replaced

909881/0402

and a bonding strength of the windshield and bodywork that meets today's requirements is achieved.

The invention accordingly relates to a method of insertion of windows, in particular of front, rear and side windows in motor vehicle bodies using a sealing profile, the method being characterized in that between the window and the body Sealing profile with elastic core and self-adhesive, permanently plastic casing. Preferably a Sealing profile with an elastic cross-section that is round, square, rectangular or adapted to the frame construction Core used, which is at least partially provided with a self-adhesive coating. The elastic Core is a fully vulcanized material, a polymer or an open- and / or closed-cell foam on rubber, synthetic rubber or be plastic-based, while permanently plastic materials are self-adhesive sheathing Butyl rubber or polyoxybutylene base are particularly suitable.

According to a particularly preferred embodiment of the invention The procedure is such that the disk is fixed in its installation position by means of the sealing profile and attached to the frame by retaining clips. The retaining clips, for example the edge of the pane, are preferably used comprehensive spring profiles, screwed to the frame.

909881/0402

Conveniently, one proceeds in such a way that one goes through by means of the elastic sealing profile and retaining clip spring profiles Bolting at specified torques a defined preload and connection strength between the washer and Frame generated. The defined preload can additionally or alternatively be achieved by retaining clips with disc springs or can be generated with telescopic springs.

The disc can be placed on spacers before it is connected to the frame be asked. Profile strips can be used as spacers, which are also used for fastening or the inclusion of cover or decorative strips. It is also possible to use the cover covering the edge of the pane or trim strips only after the pane has been attached to the frame.

It is also possible to use the retaining clips or screwed parts when inserting panes in motor vehicle bodies to the vehicle interior in such a way that mountable Inner linings, e.g. for the sky or the pillars, can be added.

The holding clamps are preferably U-shaped and with spacer springs in the form of a disc or U-profile

909881/0402

see. Welded or inserted threaded bolts generate a preload when the associated nuts are tightened between the pane and the frame flange. A defined preload is achieved through assembly using a torque wrench adjustable.

Compared to the previously customary methods, the inventive method offers A whole range of advantages, especially in vehicle construction: The assembly is quick and uncomplicated and therefore economically feasible even under assembly line conditions. That Process combines the high performance of an elastic direct connection with the simple assembly of a cold applicable, self-adhesive, permanently plastic sealing compound profile. The connection of the windshield with the body offers thus the greatest possible safety under all conceivable practical loads regardless of external temperature fluctuations. The preload and thus the spring effect can vary depending on the construction of the body cutout and the desired effects (e.g. safety aspects) can be kept variable. With torque control, the correct seat of the disc can even be checked afterwards during a routine inspection will.

It is also essential that repairs are simple and uncomplicated, since the window can also be replaced later without further can be done. Finally it is important
