Abstract

A vehicle window is held in its correct position by hook and pile-type fasteners until the permanent adhesive is fully hardened.

Description

SPECIFICATION Holding device for motor vehicle windows The invention relates to a holding device for motor vehicle windows which are held in body members by an adhesive layer. A holding device of this kind is described, for example, in German Offenlegung sschrift3243 101.

With motor vehicle windows which are glued in place, there arises the need to hold them in the correct position with holding devices until the adhesive is fully hardened. For this purpose, the known holding device comprises cams which are mounted pivotably beneath a lower edge of the windscreen and against which the windscreen abuts and thus also cannot slip down on account of its weight before the adhesive is fully hardened. For this purpose, the cams must be mounted in the vehicle body and adjusted by means of a tool. This causes, apart from the costs of the cams, considerable expenditure on assembly, and excludes the possibility of automatic assembly by means of robots.

It is the object of the invention to design a holding device of the kind mentioned hereinbefore, in such a way that it is as simple as possible in construction and allows automatic assembly of the motor vehicle windows.

According to the invention, this object is achieved bythe fact that the holding device is formed by a hook and pile-type fastener, one portion of which is attached to the motor vehicle window, and the other portion of which is attached to a body member. The term "hook and pile-type fastener" is used to denote a two part fastener, each part of which is made up of a plurality of flexibie filamentary hooks and loops secured to a planar base of material. An example of such a fastener is the two part flexible material sold under the trade name of "Velcro".

The respective motor vehicle window is held in its correct position by a hook and pile-type fastener of this kind until the adhesive is fully hardened and then takes over this function. As hook and pile-type fasteners are simple and cheap, the holding device according to the invention is far cheaper to make than the holding devices known hitherto. Furthermore, no tool is needed to allow the holding devices to become operative. It is sufficient, when the respective motor vehicle window is pressed on in its correct position, to effect engagement of the two portions of the hook and pile-type fastener, and thus fix the vehicle window. By means of the invention, therefore, automatic assembly is possible in a very simple manner.

The holding device proves particularly simple if in each case one portion of the hook and pile-type fastener is glued directly to a vehicle window. The other portion is to be attached accordingly to a body member, for example also by gluing.

Since the windows are frequently surrounded on the outside by means of a window frame, one portion of the hook and pile-type fastener can also in each case be attached to a window frame which grips the lower edge of a motor vehicle window.

In most cases, installation of a motor vehicle window is particularly easy if the portion of the hook and pile-type fastener is disposed on the window frame, on the inside of the window.

In the event that the sapce beneath the edge of the vehicle window is insufficient for mounting a hook and pile-type fastener, according to an advantageous development of the invention the hook and pile-type fastener portion can be disposed on an extension of the window frame which points away from the outer edge of the window.

Numerous embodiments of the present invention are possible. The invention and how it may be performed are hereinafter particularly described with reference to the accompanying drawings. in which: Figure 1 shows the rear part of a car in plan view of the rear window with a holding device according to the invention, Figure 2 shows a partial section taken along line ll-ll in Figure 1, as a perspective view, Figure 3 shows a plan view of an edge region of a motor vehicle window with a holding device according to the invention, Figure 4 shows a plan view of an edge region of a motor vehicle window with a further embodiment of a holding device according to the invention, and Figure 5shows a section through the window and the holding device according to Figure 4.

In Figure 1 is shown the rear part of a motor vehicle with a rear window 1. Doors 2,3 with side windows 4, 5 can be seen in part. A boot lid extending as far as the rear window 1 is marked 6.

The rear window 1 extends laterally as far as roof pillars 7,8 and upwardly as far as a vehicle roof 9.

The rear window 1 should be mounted in position by gluing. In order to hold the rear window 1 in its correct position as fitted before the adhesive fully hardens, holding devices 10, 11,which are shown in broken lines in Figure 1, are provided near the lower edge of the rear window 1. The design of these holding devices 10, 11 is essential to the invention, and is explained in more detail below with reference to Figure 2.

Figure 2 shows in section a lower region ofthe rear window 1. The latter is fixed by an adhesive layer 12 to a body member 13 which passes into a parcel shelf 14 towards the interior of the vehicle. A black border on the rear window 1 conceals the adhesive layer 12 and the holding devices 10, 11.

Adjacent a bottom edge of the rear window 1,the body member 13 supports a seal 15 on which rests the boot lid 6. Also shown is the holding device 10.

The latter consists of an upper hook and pile-type fastener portion 16 and a lower hook and pile-type fastener portion 17. It can be seen that the upper portion 16 is mounted on a window frame 18 which grips the lower edge of the rear window 1, and abuts against the rear window 1 from the inside of the rear window 1. The lower portion 17 of the hook and pile-type fastener is fixed to the body member 13.

Figure 3 shows in plan view how portion 16 of the hook and pile-type fastener is mounted on the window frame 18. It can be seen that it is connected by a corner region to the window frame 18.

By contrast with this embodiment of the invention, it is of course also possible simpiy to glue the upper hook and pile-type fastener portion 16 directly on to the rear window 1.

Another embodiment of the invention is shown by Figures 4 and 5. Here too the rear window 1 is surrounded by a window frame 18. The latter has an outwardly-directed extension 19 on which is mounted the upper portion 16 of the hook and pile-type fastener. The lower portion 17 ofthe fastener is again attached to the body member 13.

Due to this design, the holding devices 10 are located outside the region covered by the rear window 1.

The adhesive layer 12 can also be seen in Figure 5 just as in Figure 2. A sealing lip 20 on the window frame 18 prevents adhesive from reaching the hook and pile-type fastener.

The invention can be modified in many ways.

Common to all designs, however, is the basic principle that the window is pressed on in the correct position and then held by the hook and pile-type fastener. Thus the vehicle window cannot substantially shift before the adhesive layer is fully hardened. The invention has been illustrated by the example of a motor-vehicle rear window. Naturally, it can also be used on other motor vehicle windows, in particular the windscreen.
