## Background
FIELD OF THE INVENTION
The present invention generally relates to a sealing arrangement for a window pane in a vehicle body, and more particularly for a window pane which is movably arranged in a vehicle door.
BACKGROUND OF THE INVENTION
Automotive vehicles are commonly equipped with movable window panes arranged with a vehicle body, particularly the vehicle doors. The window panes are sealed closed with a sealing arrangement typically having a base body which has a receiving region for an edge region of the window pane including projections which oppose one another in the receiving region and including a first projection which extends from the outer projection of the opposing projections from a connecting point into the receiving region and in the closed state of the window pane bears against an outer face of the window pane. Such a generic sealing arrangement for a window pane is disclosed in DE 10 2006 028 051 B4.
It is also generally known to provide window panes of motor vehicle doors with rain-shielding elements, so that the window panes may be opened at least partially in spite of rain, without rain penetrating the vehicle interior, for example by running off the roof. EP 0 456 952 A1 discloses one example of a rain shield which may be bonded to the upper edge region of the door, the window pane, etc. However, this method is undesirable and also not visually acceptable. It would be desirable to provide for an enhanced sealing arrangement that offers a possibility of preventing the ingress of rain through a partially open window pane of a motor vehicle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The present illustrated embodiments preside primarily in a sealing arrangement for a window pane in a vehicle body. In the embodiment shown, the window pane is movably arranged in a vehicle body. The sealing assembly includes a base having a receiving region for receiving an edge region of the window pane and includes inner and outer projections which oppose one another in the receiving region. The sealing arrangement includes a first projection which extends from the outer projection of the opposing projections from a connecting point into the receiving region and in the closed state of the window pane bears against an outer face of the window pane. The sealing arrangement further includes a second projection on the outer projection of the opposing projections extending outwardly from the connecting point. The second projection may serve as a rain shield, as in the manner of a rain channel to prevent the ingress of water from above the window pane, in particular from the vehicle roof, when the window pane is open. The length of the second projection is variable depending on requirements but generally it will be longer than that of the first projection.
In the embodiment shown and described herein, in the open state of the window pane the first projection protrudes into the receiving region such that the first projection comes into contact with the upper edge region of the window pane when the window pane is inserted and thus effects a pivoting movement of the first and second projections about the connecting point. The first projection thus acts as a sealing element and at the same time effectively acts as a pivot lever which also effects the movement of the second projection in the manner of a hinge about the connecting point. Thus, the first and second projections are able to be pivoted together about the connecting point.
For improving the seal and at the same time for shortening the pivoting path, the second projection may have on its outer end a thickened portion oriented in the direction of the window pane, which then bears against the window pane in the closed state affecting the seal. For improving the rain channel function the second projection may have a convex shape (oriented outwardly).
Also, in the closed state of the window pane the second projection may bear against an outer face of the window pane. Thus, in the closed state both projections bear externally against the window pane and affect the desired labyrinth seal. In order to improve the pivoting movement of the projections, it is expedient if the connecting point has a narrowed portion oriented toward the receiving region.
The sealing arrangement is shown, according to one embodiment in the FIGS. 1 and 2 having a base body 2, which has a receiving region 3 for receiving a window pane 1. The receiving region 3 in this case is formed by a substantially U-shaped partial region of the base body 2 in sectional view, wherein to this end the base body 2 includes an inner projection 21 and an outer projection 22. The inner and outer projections 21 and 22 have different dimensions and shapes in the exemplary embodiment.
A first projection 4 extends from the outer projection 22 of the opposing projections 22 from a narrowed connecting point 10 into the receiving region 3 and bears against an outer face 11 of the window pane 1 in the closed state of the window pane 1 as illustrated in FIG. 2. A second projection 5 also extends on the outer projection 22 of the opposing projections 22 from the connecting point 10, but extends outwardly. The first and second projections 4, 5 are configured to be pivoted together about the connecting point 10.
In the open state of the window pane as illustrated in FIG. 1, the first projection 4 protrudes into the receiving region 3 such that the first projection 4 comes into contact with the upper edge region 1a of the window pane 1 when the window pane 1 is inserted and thus effects a pivoting movement of the first and second projections 4, 5 about the connecting point 10. Thus, both projections 4, 5 in the closed state of the window pane 1 as shown in FIG. 2 bear against the outer face 11 of window pane 1 as a labyrinth seal. To this end, the second projection 5 includes a thickened portion 6 on its outer end oriented in the direction of the window pane 1.
The connecting point 10 has a narrowed portion E oriented toward the receiving region 3 in order to simplify the movement of the two projections 4, 5. The second projection 5 has a convex shape so that it more effectively fulfills its function as a rain channel by conducting water in the recess formed by the convex shape.
The sealing arrangement and, in particular, the base body 2 also have, as described in DE 10 2006 028 051 B4, a bulged sealing element 23 which bears with its upper surface 23a against an inner face of the window pane 1 when the window pane is inserted into the closed state.
A further receiving region A is configured in the base body 2. A bodywork flange K of the vehicle door is shown received in the receiving region A. In the embodiment shown, this bodywork flange K includes an opening-out region 71 which penetrates the receiving region A and is sealed.
Accordingly, the sealing arrangement advantageously provides for a first projection and a second projection that extends outwardly from the connecting point to serve as a rain shield or channel to prevent the ingress of water above the movable window pane within a vehicle door when the window pane is open. The sealing structure advantageously pivots due to movement of the first and second projections about the connecting point as the window pane moves from the closed to open position. It should be appreciated that the sealing arrangement may likewise be useful for a movable window pane arranged in other structures.
It is to be understood that variations and modifications can be made on the aforementioned structure without departing from the concepts of the present invention, and further it is to be understood that such concepts are intended to be covered by the following claims unless these claims by their language expressly state otherwise.
