Description

TECHNICAL FIELD

The present invention relates generally to vehicle doors with sash constructions, and particularly to mounting assemblies that attach glass runs and appliques to a vehicle door.

BACKGROUND

Vehicle doors with sash constructions typically include mounting assemblies that attach a glass run and an exterior applique to a main door body. The typical mounting assembly is a sheet metal construction, which can determine vehicle craftsmanship and functional attributes. For example, the sheet metal construction can determine the distance from the outer surface of the glass windowpane to adjacent exterior surfaces. In this regard, the mounting assembly can determine the smoothness of the overall vehicle exterior surface.

Referring to FIG. 1, one known mounting assembly 10 is comprised of a one-piece sheet metal construction 12 with an overlapped portion 14 defining an interior channel 16 and an exterior surface 18. The interior channel 16 typically receives the glass run (not shown), which is an elastomeric seat that receives an end portion 20 of the windowpane 22 when the window is in the closed position. In this respect, the glass run can seal the windowpane 22 closed and cushion the windowpane 22. Furthermore, the exterior surface 18 of the mounting assembly 10 along with one or more adjacent exterior vehicle structures (not shown) typically have an appliqué (not shown) attached thereto. It is understood that the appliqué is offset from the windowpane 22 by the thickness (2T) of the overlapped portion 14 of the sheet metal 12. In other words, the appliqué is offset from the windowpane 22 by at least twice the thickness (T) of the sheet metal 12.

It would therefore be desirable to provide a mounting assembly that minimizes the offset distance between the appliqué and the windowpane and thus decreases air drag on the vehicle and streamlines the vehicle design.

SUMMARY OF THE INVENTION

A glass run mounting assembly (“mounting assembly”) for a vehicle door is provided. The mounting assembly includes an elongated stepped bracket and an elongated plate attached to the elongated stepped bracket. The elongated plate and the elongated stepped bracket define a channel with a glass run retention member therein. The elongated plate has an outer surface, an inner surface, and a wall thickness therebetween. The outer surface mounts an appliqué to the vehicle door. The elongated plate offsets the appliqué from the glass pane substantially by one wall thickness of the elongated plate.

One advantage of the present invention is that a glass run mounting assembly is provided that minimizes the glass offset and thus decreases vehicle drag.

Another advantage of the present invention is that a glass run mounting assembly is provided that increases the smoothness in the exterior vehicle contour and enhances the vehicle design.

Yet another advantage of the present invention is that a glass run mounting assembly is provided that improves flushness of an appliqué to the exterior vehicle surfaces.

Still another advantage of the present invention is that a glass run mounting assembly is provided that improves the fuel economy of a vehicle.

Yet another advantage of the present invention is that a glass run mounting assembly is provided that enhances the vehicle acceleration.

Other advantages of the present invention will become apparent upon considering the following detailed description and appended claims, and upon reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION

In the following figures, the same reference numerals are used to identify the same components in the various views.

The present invention is particularly suited for a glass run mounting assembly for a vehicle door. In this way, the embodiments described herein employ structural features where the context permits. However, various other embodiments are contemplated having different combinations of the described features, having features other than those described herein, or lacking one or more of those features. Thus, it is contemplated that the invention can be carried out in a variety of other modes and utilized for other suitable applications as desired. For instance, the invention can be integrated within a variety of other suitable vehicle structures as desired.

Referring to FIG. 2, there is shown a vehicle 24 having a door 26 with a windowpane 25 sealingly mounted therein by a glass run mounting assembly 27 (“mounting assembly”) (shown in FIGS. 2 and 3). The door 26 is pivotally attached to an A-pillar structure 28 of the vehicle 24 with the mounting assembly 27 adjacent to the B-pillar structure 30. As detailed below, the mounting assembly 27 minimizes the distance by which the outer surface 32 of the windowpane 22 is offset inboard from adjacent exterior surfaces, such as an appliqué 34. In this respect, the mounting assembly 27 provides a substantially streamlined overall vehicle exterior surface, decreases the drag on the vehicle 24, improves the fuel economy for the vehicle 24, enhances the vehicle acceleration, and improves the aesthetic appearance of the vehicle 24.

In the embodiment shown in FIGS. 3 and 4, the mounting assembly 27 is attached to a door inner 36 for the door 26. The mounting assembly 27 includes an elongated stepped bracket 38, an elongated plate 40, a glass run retention member 42 (“retention member”), and the appliqué 34.

As best shown in FIG. 4, the elongated stepped bracket 38 and the elongated plate 40 have sheet metal constructions defining a channel 44 with the retention member 42 seated therein. The retention member 42 is comprised of an elastomeric material for sealing an end portion 20 of the windowpane 22 and cushioning the same. In this embodiment, the elongated stepped bracket 38 and the elongated plate 40 have a pair of opposing ridges 46a, 46b or other suitable retention protrusions extending therefrom for press-fitting the retention member 42 within the channel 44. It is contemplated that the elongated stepped bracket 38, the elongated plate 40, and the retention member 42 can instead be comprised of various other suitable materials.

The stepped bracket 38 has a series of planar portions extending along its length. These planar portions include an inner planar portion 48, a clearance planar portion 50, a first channel planar portion 52, a second channel planar portion 54, and an outer planar portion 56. The inner planar portion 48 is welded or otherwise suitably attached to the door inner 36. Also, the outer planar portion 56 has the elongated plate 40 welded or otherwise suitably attached thereto.

The clearance planar portion 50 extends substantially perpendicularly from the inner planar portion 48 so as to position the windowpane 22 a predetermined distance from the door inner 36. The first channel planar portion 52 extends substantially perpendicularly from the clearance planar portion 50 and distal to the inner planar portion 48. The second channel planar portion 54 extends substantially perpendicularly from the first channel planar portion 52 and distal to the clearance planar portion 50. The first and second channel planar portions 52 and 54 are sufficiently sized for receiving the depth and width of the retention member 42. The outer planar portion 56 extends substantially perpendicularly from the second channel planar portion 54 and distal to the first channel planar portion 52.

The elongated plate 40 has an outer surface 57, an inner surface 58, and a wall thickness (T) therebetween. The inner surface 58 of the elongated plate 40 has a channel surface portion 60 and an attachment surface portion 62 adjacent thereto. The attachment surface portion 62 is welded or otherwise suitably attached to the outer planar portion 56 of the elongated stepped bracket 38. Furthermore, the channel surface portion 60 of the elongated plate 40 assists in defining the channel 44. The outer surface 32 has the appliqué 34 attached thereto. In this embodiment, the appliqué 34 is attached exclusively to the elongated plate 40. This feature is beneficial for eliminating the need for aligning the appliqué 34 with two or more mounting fixtures and thus decreases the installation time associated therewith. However, it will be appreciated that the appliqué 34 can be mounted to two or more mounting fixtures as desired.

Also, as introduced above, the ridges 46a, 46b extend respectively from the first channel planar portion 52 of the elongated stepped bracket 38 and the channel surface portion 60 of the elongated plate 40.

As best shown in FIG. 4, the elongated plate 40 is substantially planar and extends unilaterally across the elongated stepped bracket 38. In this respect, the appliqué 34 is offset from the outer surface 32 of the windowpane 22 substantially by one wall thickness (T) of the elongated plate 40. Accordingly, the mounting assembly 27 positions the appliqué 34 substantially close to the outer surface 32 of the windowpane 22 and thus provides a more streamlined vehicle exterior surface. As introduced above, this feature is beneficial for minimizing the vehicle drag, improving fuel economy, increasing vehicle acceleration, and enhancing vehicle design.

While particular embodiments of the invention have been shown and described, it will be understood, of course, that the invention is not limited thereto since modifications may be made by those skilled in the art, particularly in light of the foregoing teachings. Accordingly, it is intended that the invention be limited only in terms of the appended claims.
