Abstract

A motor vehicle window comprises an aperture in the vehicle body and a window pane (1), the side and top edges (2, 3) of the window pane being secured in the aperture by means of a weatherstrip (4) and the bottom edge (5) being secured by an adhesive (10). Buffer blocks (6) may be arranged along the bottom edge to support the window pane (1). <IMAGE>

Description

SPECIFICATION Motor vehicle window The invention relates to motor vehicle windows.

DE-C-2723255 discloses a fixed motor vehicle window in which a pane of glass is enclosed on its lateral edges and on its upper edge by an elastic sealing strip. The body aperture in which the pane is mounted has a U-shaped channel between an outer edge and an inner peripheral mounting flange. The opposite lateral areas of the body aperture converge towards each other, and, in order to insert the pane of glass into the aperture, the upper edge of the pane must be positioned a considerable distance below its normal position in relation to the body aperture and then pushed upwardly into the U-shaped channel of the body aperture. The lower edge of the pane must then be sealed, by means of a sealing strip or an elastic sealing compound, and fixed.

This known weatherstrip has a series of disadvantages. For example the U-shaped channel provided in the body aperture is expensive to manufacture. The weatherstrip moreover can only be used with panes with converging lateral edges and its assembly requires a great deal of space and effort because of the necessary upward pushing movement and subsequent fixing.

According to the invention there is provided a motor vehicle window comprising an aperture in the body of the motor vehicle having a mounting flange positioned inwardly from the outer edge of the aperture to form a step therearound, and a window pane mounted in the aperture with its edges overlying the mounting flange, the side and top edges of the window pane being secured in the aperture by means of a weatherstrip, the bottom edge of the window pane being secured to the bottom edge of the aperture by adhesive.

Since the body aperture has a step formation extending from its outer edge to the mounting flange, the construction of the body aperture is relatively simple and, since the pane of glass is held at this step at its lower edge by adhesive, difficult upward pushing processes and fixing operation are no longer required in assembly.

The invention is explained in greater detail with the aid of an exemplary embodiment thereof shown in the accompanying drawings, in which: Figure 1 is a front view of a weatherstrip according to the invention mounted on a pane of glass; Figure 2 is a cross-sectional along the line Il-Il of Fig. 1; Figure 3 is a cross-section along the line Ill-Ill of Fig. 1; and Figure 4 is a cross-section along the line IV-IV of Fig. 1.

In Fig. 1 a pane of glass 1 is enclosed at its lateral edges 2, indicated by dotted lines, and at its upper edge 3 by an elastic weatherstrip 4 extending along these edges.

The lower edge 5 of the pane of glass 1 is supported by.angular buffer blocks 6 which can be fixed to a body plate by screws, rivets or suchlike or, alternatively as shown in Fig.

2, are simply supported on a step 9 formed in the edge of a body aperture between the edge of the outer panel 7 of the body and a mounting flange 8.

The lower edge 5 of the pane of glass 1 is additionally stuck to the mounting flange 8 by a strip of suitable polymeric adhesive 10, which is indicated in Fig. 1 in broken lines.

As can be seen from the cross-sections in Fig. 2 to Fig. 4, the weatherstrip 4 surrounding the lateral areas and the upper area of the pane has a cross-sectional shape which defines an outer groove for gripping the mounting flange 8, an inner groove for gripping the edges of the pane of glass 1, and a lip which seals the gap between the edge of the pane of glass 1 and the edge of the outer panel 7.

The weatherstrip is assembled on to the pane of glass and the assembly is then inserted into the aperture in the body panel, such insertion being accomplished by means of a cord (not shown), placed around the edge of the strip, in a well known manner. The upward pressure exerted by the buffer blocks ensures a good seal between the pane of glass 1 and the weatherstrip. The buffer blocks also avoid sagging of the pane of glass in the elastic sealing profile.

1. A motor vehicle window comprising an aperture in the body of the motor vehicle having a mounting flange positioned inwardly from the outer edge of the aperture to form a step therearound, and a window pane mounted in the aperture with its edges overlying the mounting flange, the side and top edges of the window pane being secured in the aperture by means of a weatherstrip, the bottom edge of the window pane being secured to the bottom edge of the aperture by adhesive.

2. A window according to Claim 1 wherein the window pane is supported at its bottom edge by buffer blocks.

3. A motor vehicle window substantially as hereinbefore described and as illustrated in the drawings.
