## Title
Fluid management system for a windshield wrapped vehicle pillar

## Abstract

A vehicle having a fluid management trim system includes a windshield supported along a lower edge by a cowl, along an upper edge by a roof, and along a side edge by a pillar. The pillar extends from a side door toward the roof, and a trim member extends along the side edge of the windshield forming a channel for guiding fluid along the windshield toward a drain. The side edge of the windshield may extend at least partially around the pillar. Even more, the side edge of the windshield may extend from the lower edge to a first position below the upper edge forming the drain. A portion of the trim member may be offset to the windshield forming the channel and extends from the lower edge to a second position below the upper edge and over the drain.

## Background
TECHNICAL FIELD
This document relates generally to fluid management for vehicle windshields, and more specifically to a fluid management trim used with a windshield wrapped A-pillar.
BACKGROUND
The A-pillar of a vehicle is the front most pillar or vertical support on a vehicle. All vehicle pillars are located around vehicle glass and operate to hold the glass in place and add structural integrity primarily to the roof of the vehicle. The A-pillar generally holds the windshield in place along driver and passenger side edges. Recent design trends following customer preferences indicate a desire for the A-pillar to appear dark or black in color such that the roof appears to be floating. To achieve the desired appearance, factory installed pillars are commonly covered. This has historically been achieved in three different ways.
First, the A-pillar is masked off and painted black after the vehicle is painted its original color. This approach, however, is time and labor intensive and perhaps most importantly requires a significant amount of additional painting facilities. Together, these additional requirements slow production and increase manufacturing costs. Second, black tape or the like is added to the A-pillar. While sufficient to create the desired black colored pillars, application of the tape is limited to certain contours and is also time and labor intensive. Even more, the tape may not be very robust in the field.
Third, a black colored applique is added. Typically, the applique is mounted to a bracket that is itself mounted to the A-pillar. Mounting the bracket to the A-pillar, however, is not without issues because the A-pillar is characteristically designed to be small and compact, and developing and packaging fasteners sufficient to hold the applique is challenging. The design issues are further complicated by recent increases in roof strength requirements that dictate the use of metal tubes to stiffen the A-pillars. Maintaining clearance for applique fasteners when using the metal tubes or the like is difficult.
Even more, post applied appliques are known to suffer from significant wind noise and/or retention issues. While the use of added epoxy adhesive can significantly reduce, if not eliminate, such issues, the additional adhesive increases the cost of manufacturing. The additional appliques and brackets also contribute to increases in manufacturing costs and add approximately 1.2 Kg to the overall weight of the vehicle. In addition, the appliques limit the range of travel of the windshield wipers as the wiper blades have to stop approximately 50 mm short of the applique to prevent contact with the applique. The result is that the wiper blades do not clear the windshield all the way to the A-pillars.
One solution for providing the customer with a blacked out A-pillar while overcoming the noted drawbacks associated with painting, taping and/or adding an applique, i.e., without reducing quality (e.g., through the introduction of wind noise due to a loose applique or a missing applique), increasing the cost or weight of the vehicle, and/or while maintaining at least the required strength in the pillar is to extend the edges of the windshield at least partially over the A-pillars. One potential drawback of such a solution, however, is the possible transference of fluid, whether rain, wiper fluid, or the like, from the windshield into the side windows in certain vehicle designs. Accordingly, a need exists for a fluid management system that ensures that fluid is prevented from entering the side windows. One way to meet these needs is using a trim member which moves the fluid along the windshield and away from the side windows.

DETAILED DESCRIPTION
Reference is now made to FIG. 1 which shows an embodiment of a vehicle 10 having a windshield 12 that extends around driver and passenger side A-pillars 14, 16. As shown, the windshield 12 is supported along a lower edge 18 by a cowl 20 and along an upper edge 22 by a roof 24. The first, or driver side, A-pillar 14 extends between a driver side door 26 (and door seal 27) and the roof 24 and supports a driver side edge 28 of the windshield 12. A second, or passenger side, A-pillar 16 similarly extends between a passenger side door 30 and the roof 24 and supports a passenger side edge 32 of the windshield 12.
As described in greater detail below, a first trim member 34 extends along and is supported by the passenger side edge 32 of the windshield 12 forming a gutter within which fluid travels along the windshield. A second trim member 36, similarly extends along and is supported by the driver side edge 28 of the windshield 12 forming a gutter. It should be noted that references to edges of the windshield 12 (e.g., driver side edge 28) refer to a portion of a face or rear face of the windshield adjacent a side of the windshield, the line where the face meets the side of the windshield, and/or the side of the windshield).
As shown in FIG. 2, the second trim member 36 extends along and is supported by the driver side edge 28 of the windshield 12. More specifically, the second trim member 36 is attached to a face of the windshield 12. In the described embodiment, the second trim member 36 is bonded to the face of the windshield utilizing an adhesive or the like. Of course, other methods of attaching the trim member may also be utilized and the trim member may be attached to a side of the windshield 12 or both. Although not shown in this figure, it should be noted that the first trim member 34 is similarly situated on the passenger side of the vehicle 10. Given the similarities and essentially mirrored image of the trim members in the described embodiment, the passenger side trim member will not be further described.
The second trim member 36 includes an outboard portion 38 which is attached to the windshield 12 and an inboard portion 40. As best shown in FIG. 3, the inboard portion 40 includes a first portion 42 offset to the windshield 12. The first portion 42 forms the gutter using the windshield 12 and second trim member 36. A second portion 44 of the inboard portion 40 is substantially flush to the windshield 12 over at least a portion of a drain 46 as shown in FIG. 4. A seal 48 (e.g., a lip seal) is used to seal a gap between the windshield 12 and the second portion 44 of the inboard portion 40 of the second trim member 36.
Returning to FIG. 2, reference numeral 46 generally shows the drain which is essentially a notch or void formed in an upper corner of the driver side edge 28 of the windshield 12 in the described embodiment. The drain 46 may take any form sufficient to allow fluid to pass through the windshield 12 and need not be limited to the upper corners of the windshield.
In the described embodiment, the notch is defined by a notch side edge 50 and a notch top edge 52. As shown, an upper edge 54 of the second trim member 36 extends past the notch top edge 52 in the described embodiment to allow the fluid to enter the drain 46 before the second portion 44 of the inboard portion 40 and a second portion 56 of the outboard portion 38 of the second trim member 36 become flush with the windshield 12 and the A-pillar 14 and door 26 over the drain such that the drain is hidden from view outside of the vehicle 10. In alternate embodiments, one or both of the second portion 44 of the inboard portion 40 and the second portion 56 of the outboard portion 38 of the second trim member 36 may remain elevated above the windshield 12.
As shown by action arrows A, airflow onto the windshield 12 when the vehicle 10 is moving forward pushes fluid to the side edge 28 of the windshield. There, the fluid is collected within the gutter formed by the second trim member 36 and the windshield 12, and directed or guided up the windshield and into the drain 46. Once the fluid enters the drain 46, the effect of the airflow is minimized and the fluid simply drains out the bottom of the A-pillar 14 between the windshield 12 and the A-pillar due to the effects of gravity.
The foregoing has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the embodiments to the precise form disclosed. Obvious modifications and variations are possible in light of the above teachings. All such modifications and variations are within the scope of the appended claims when interpreted in accordance with the breadth to which they are fairly, legally and equitably entitled.
