DETAILED DESCRIPTION OF EMBODIMENTS
Selected embodiments will now be explained with reference to the drawings. It will be apparent to those skilled in the art from this disclosure that the following descriptions of the embodiments are provided for illustration only and not for the purpose of limiting the invention as defined by the appended claims and their equivalents.
Referring initially to FIG. 1, a vehicle 10 is illustrated in accordance with a first embodiment. The vehicle 10 includes a roof structure 12 with floating appearance (a floating roof design) that is in part due to exterior trim panels 14. The exterior trim panels 14 are a dark color, for example, black, giving the effect of having a floating roof, as described in greater detail below.
First, a brief description of various features of the vehicle 10 is provided below with specific reference to FIG. 1-12. The vehicle 10 has a vehicle body structure 20 that includes, among other things, an A-pillar 22, a B-pillar 24, a rear body panel 28 and the roof structure 12. A front door opening 30 is partially defined by the A-pillar 22, the B-pillar 24 and a portion of the roof structure 12, in a conventional manner. A rear door opening 32 (a side opening) is partially defined by the B-pillar 24, another portion of the roof structure 12 and the rear body panel 28. Further, a rear window opening 34 is partially defined by the rear body panel 28 and a rear portion of the roof structure 12. A trunk opening 36 is partially defined by the rear body panel 28 and by a lower window support member 38 (FIG. 8), at a lower area of the rear window opening 34. In FIG. 8, a trunk lid 46 has been removed to show the trunk opening 36 and the lower window support member 38. Beneath the window opening 34, within the passenger compartment of the vehicle 10, a rear parcel shelf P is visible. The rear parcel shelf P extends from the back of a rear seat (not shown) to the lower window support member 38. The rear parcel shelf P serves to separate the passenger compartment of the vehicle 10 from the trunk area T of the vehicle 10.
There are two rear body panels 28 and two exterior trim panels 14, one on each side of the vehicle 10 with the lower window support member 38 extending therebetween at a lower edge of the rear window opening 34 (see FIG. 8). The rear body panels 28 are identical to one another except that they are symmetrical mirror images of one another. Similarly, the exterior trim panels 14 are identical to one another except that they are symmetrical mirror images of one another. Therefore only one of the rear body panels 28 and one of the exterior trim panels 14 are described hereinbelow for the sake of brevity, since description of one equally applies to the other.
A front door 40 is installed to the A-pillar 22 for pivoting movement between a closed position (shown in FIGS. 1 and 2) and an open position (not shown) in a conventional manner. In the closed position, the front door 40 covers the front door opening 30. A rear door 42 is installed to the B-pillar 24 for pivoting movement between a closed position (shown in FIGS. 1 and 2) and an open position (not shown). In the closed position, the rear door 42 covers the rear door opening 32 in a conventional manner.
The front door 40 includes a window opening with a forward side window 40a moveably installed thereto in a conventional manner. The rear door 42 similarly includes a window opening with a first rearward side window 42a, a second rearward side window 42b, a divider 42d between the first rearward side window 42a and the second rearward side window 42b, and a non-transparent panel 42c at the rearward end of the rear window opening 34. A rear window glass 44 is fixedly installed to the vehicle body structure 20 covering the rear window opening 34. A trunk lid 46 is pivotally coupled to the vehicle body structure 20 in a convention manner for movement between a closed position (shown in FIGS. 2-6) and an open position (not shown).
The forward side window 40a, the first rearward side window 42a, the second rearward side window 42b, the non-transparent section 42c, and the rear window glass 44 have respective lower edges that together define respective portions of a vehicle body waistline W. The vehicle body waistline W is a conventional automotive expression that is defined as an imaginary line around a car or other vehicle at the level of the bottom of the windows. The vehicle body waistline W is depicted in several of the figures with a dashed line.
The A-pillars 22 are provided with a dark or black appearance on an exterior surface thereof. For example, a trim panel can be fitted on to each of the A-pillars 22 and can include a black paint or black finish. Alternatively, the A-pillar 22 can be assembled with an outer panel that is made of a black material.
Similarly, the front door 40 includes a rear trim panel that covers the B-pillar 24 in the closed position and the rear door 42 includes a front trim panel that also covers the B-pillar 24. The rear trim panel of the front door 40 and the front trim panel of the rear door 42 are dark in color or are black. These panels can be made of a black material or can be painted black to achieve the floating roof effect.
The rear body panel 28 is now described in greater detail with specific reference to FIGS. 2, 3 and 5-11. The rear body panel 28 is a contoured element of the vehicle body structure 20 that can be manufactured as a single element, or can be made of several different panels welded or otherwise rigidly fixed to one another. In the depicted embodiment, the rear body panel 28 is a single piece that includes a roof rail portion 50, a pillar portion 52 and a fender portion 54. The roof rail portion 50 extends along the side of the roof structure 12 above the front door opening 30 and above the rear door opening 32. The roof rail portion 50 can be part of the roof structure 12, or can be a panel that covers a roof rail (not shown) of the roof structure 12.
The pillar portion 52 extends downward and rearward from the roof rail portion 50 between the rear door opening 32 and the rear window opening 34. The fender portion 54 extends downward from the pillar portion 52 and defines a rear section of the vehicle 10, including a wheel well 48 (shown in FIGS. 1 and 2). The pillar portion 52 of the rear body panel 28 covers and/or forms part of a C-pillar structure (not shown) of the vehicle 10.
The vehicle body waistline W basically defines an approximate boundary between the pillar portion 52 and the fender portion 54, as is clear from the description hereinbelow. The rear body panel 28 has an outboard surface 28a (FIGS. 1-9), a rearward facing surface 28b and an inboard surface 28c (shown only in FIG. 10).
The pillar portion 52 includes the following: a forward peripheral end 58 that defines a door jamb 60 of the rear door opening 32 (FIGS. 7, 9, 10 and 11); a rearward peripheral end 62 adjacent to the rearward facing surface 28b that includes a rear window supporting flange 64 (FIGS. 4, 8, 9 and 23); and a recess 66 that extends from the forward peripheral end 58 to the rearward peripheral end 62 of the pillar portion 52. The door jamb 60 basically defines a front peripheral edge section of the rear body panel 28.
The pillar portion 52 has a contoured surface that includes compound curves. In the depicted vehicle body structure 20, there is no clear dividing line between the roof rail portion 50 and the pillar portion 52. Rather, the roof rail portion 50 and the pillar portion 52 have the appearance of being one single contoured element. However, it should be understood from the drawings and the description herein that the roof rail portion 50 and the pillar portion 52 can be altered such that there is a clear distinction between the two portions of the rear body panel 28.
The pillar portion 52 curves downward and rearward from a point above the rear door opening 32 moving down toward the vehicle body waistline W. The outboard surface 28a of the rear body panel 28 is therefore not a flat surface in the depicted embodiment. Further, as shown in FIG. 5-7, the pillar portion 52 of the rear body panel 28 has a curve extending inboard toward the rear window opening 34 thereby defining the rearward facing surface 28b. As indicated in FIG. 8, the lower window support member 38 extends along the lower edge of the rear window opening 34 and is rigidly attached to the pillar portion 52. However, it should be understood that at least a portion of the lower window support member 38 can be integrally formed with the pillar portion 52 of the rear body panel 28.
As shown in FIGS. 8, 9 and 11, the recess 66 of the pillar portion 52 is defined by a plurality of contoured surfaces. Specifically, the recess 66 includes a lower surface 70, a main surface 72 and an upper surface 74. The lower surface 70 also includes a rear section 70a that curves in an inboard direction and extends to a bottom corner of the rear window opening 34, as shown in FIGS. 8 and 9. A side section 70b of the lower surface 70 basically faces upward and extends in a vehicle longitudinal direction D along the vehicle body waistline W from the rear section 70a to the forward peripheral end 58.
The main surface 72 also includes a rear section 72a, a side section 72b and a forward section 72c. The rear section 72a curves in an inboard direction from the side section 72b and extends to the rear window opening 34, as shown in FIGS. 8 and 9. The rear section 72a is wider than the side section 72b, as measured between the lower surface 70 and the upper surface 74. The rear section 72a is also inclined with respect to vertical by an angle α (FIG. 1) that is between 50 and 75 degrees. In the depicted embodiment, the rear section 72a includes portions that are inclined by an angle of approximately 70 degrees with respect to vertical.
The side section 72b extends in the vehicle longitudinal direction D along a majority of a lower area of the pillar portion 52 from the rear section 72a to the forward section 72c. The forward section 72c is wider in a vertical direction than the side section 72b such that at the door jamb 60, the lower surface 70 and the upper surface 74 are further apart from one another than at the side section 72b of the main surface 72 of the recess 66. More specifically, moving in a forward direction, the lower surface 70 and the upper surface 74 diverge, moving away from one another as they extend to the door jamb 60. The forward section 72c of the main surface 72 extends from the side section 72b to the door jamb 60.
The rear section 72a of the main surface 72 of the recess 66 includes an attachment aperture 80a. The side section 72b includes a plurality of attachment apertures 80b and an alignment aperture 82b. The forward section 72c of the recess 66 includes a pair of attachment apertures 80c and an alignment aperture 82c. The attachment aperture 80a, the attachment apertures 80b and the attachment apertures 80c constitute first attachment portions.
The upper surface 74 of the recess 66 includes a rear section 74a, a side section 74b and a forward section 74c. The rear section 74a curves in an inboard direction and extends from the side section 74b to the rear window opening 34 above the bottom corner of the rear window opening 34, but well below and spaced apart from an upper end of the rear window opening 34, as shown in FIGS. 8 and 9. The side section 74b of the upper surface 74 basically extends in the vehicle longitudinal direction D along the recess 66 from the rear section 74a to the forward section 74c. The forward section 74c extends slightly upward moving in the vehicle forward direction D from the side section 74b to the door jamb 60.
As shown in FIGS. 3-8, the rear window glass 44 includes a transparent section 44a and a non-transparent section 44b. The transparent section 44a is centrally located and provides full visibility therethrough. The transparent section 44a makes up the majority of the rear window glass 44. The non-transparent section 44b include a dark, light blocking material, such as a paint or tape fixed to an interior side of the rear window glass 44 along the peripheral edge thereof. The non-transparent section 44b serves any of a variety of purposes. First, the non-transparent section 44b covers, hides and/or obscures the sealing/adhesive material that fixedly attaches the rear window glass 44 to the lower window support member 38, the rear window supporting flanges 64 of each of the two rear body panels 28 and a window supporting flange 12a that extends into the rear window opening 34 from the roof structure 12. Second, since the non-transparent section 44b can be defined by a black, non-transparent (and optionally non-translucent) material, the non-transparent section 44b serves as a design feature of the vehicle 10. The exterior trim panel 14 is dimensioned to align and blend in with a lower area of the non-transparent section 44b along the vehicle body waistline W to provide the floating roof effect.
The roof structure 12 includes a plurality of panels (not shown). It should be understood from the drawings and the description herein that the roof rail portion 50 of the rear body panel 28 can cover a roof rail assembly of the roof structure 12 or can be an integral part of the roof rail assembly of the roof structure 12. Since roof rails and roof structures are conventional in nature, further description is omitted for the sake of brevity.
The exterior trim panel 14 is now described with specific reference to FIGS. 13-23. The exterior trim panel 14 includes a front end 84, a rear end 86, a lower edge 88, an upper edge 90 an outboard surface 92 and an inboard surface 94 (FIG. 17). The exterior trim panel 14 further includes a front section 96, a middle section 98 and a rear section 100. The exterior trim panel 14 also includes a chrome trim member 108, that is described in greater detail below
In the depicted embodiment, the exterior trim panel 14 has a contoured shape with few straight lines. Specifically, the front section 96 is defined between diverging sections of the lower edge 88 and the upper edge 90. The front section 96 extends to the door jamb 60 with the exterior trim panel 14 installed to the recess 66 of the rear body panel 28. The front section 96 and the middle section 98 extend in the vehicle longitudinal direction D when installed to the recess 66, with the middle section 98 extending rearward from the front section 96 to the rear section 100. However, the rear section 100 curves from the middle section 98 in a lateral inboard direction I such that the rear section 100 extends to the rear window opening 34 with the exterior trim panel 14 installed to the recess 66 of the rear body panel 28. The rear section 100 is also contoured such that the rear section 100 is inclined with respect to vertical by the angle α, as indicated in FIG. 1. More specifically, the exterior trim panel 14 has surfaces and contours that are specifically configured to fit into and overlay the surfaces of the recess 66. Further, the middle section 98 generally extends in the vehicle longitudinal direction D, while the rear section 100 extends in the lateral inboard direction I, such that the rear section 100 is angularly offset from the vehicle longitudinal direction D by an angle of between 65 degrees and 90 degrees.
As indicated in FIG. 8, when the exterior trim panel 14 is installed in the recess 66, the front section 96 covers the forward section 72c of the main surface 72 of the recess 66. The middle section 98 covers the side section 72b of the main surface 72 of the recess 66, and the rear section 100 covers the rear section 72a of the main surface 72 of the recess 66.
As shown in FIG. 12, when installed in the recess 66, the lower edge 88 overlays the lower surface 70 of the recess 66 and the upper edge 90 overlays the upper surface 74.
As shown in FIG. 13, the front end 84 of the exterior trim panel 14 is generally flat and faces forward when installed to the recess 66. As shown in FIG. 12, when installed in the recess 66, the front end 84 is in approximate alignment with the door jamb 60 (the front peripheral edge section of the rear body panel 28).
As shown in FIGS. 4 and 23, the rear end 86 of the exterior trim panel 14 has a flat contour and aligns with the rearward peripheral end 62 of the pillar portion 52 of the rear body panel 28.
When installed to the recess 66, the lower edge 88 of the exterior trim panel 14 coincides with the vehicle body waistline W. In other words, a rear end of the lower edge 88 of the exterior trim panel 14 is in alignment with a lower edge of the rear window glass 44 and a front end of the lower edge 88 is in alignment with a lower edge of the non-transparent section 42b of the rearward side window 42a of the rear door 42.
As shown in FIG. 17, the inboard surface 94 of the exterior trim panel 14 is provided with a plurality of clips C and a pair of alignment pins A that constitute second attachment portions. The clips C are shown removed from the inboard surface 94 in FIGS. 18 and 19. The clips C attach to the inboard surface 94 in a conventional manner, for instance, by receiving attachment projections or sliding into groove portions formed on the inboard surface 94. The alignment pins A are rigidly fixed to or integrally formed with the inboard surface 94 in order to ensure proper positioning of the exterior trim panel 14 relative to the rear body panel 28. FIG. 10 is a view of the inboard surface 28c of the rear body panel 28 showing the attachment clips C extending through the attachment apertures 80a, 80b and 80c and the alignment pins A extending through the alignment apertures 82b and 82c. 
In FIG. 20, two of the clips C attached to the inboard surface 94 at the middle section 98 of the exterior trim panel 14 are visible and also extend parallel to one another. Further, the snap-fitting projections of those two clips C are parallel to one another, with the rearmost one of the clips C extending in a first direction D1, as shown in FIG. 20. The rear section 100 is angularly offset about vertical axis and angularly inclined with respect to vertical, and relative to the middle section 98 of the exterior trim panel 14, as is described above. The snap-fitting projection of the clip C installed to the rear section 100 of the exterior trim panel 14 is also angularly offset and angularly inclined with respect to the clips C on the middle section 98. Specifically, the clip C installed to the rear section 100 extends in a second direction D2 that is angularly offset from the first direction D1. More specifically, the first direction D1 and the second direction D2 are offset from one another by an angle γ that is between 65 and 85 degrees. In the depicted embodiment, the angle γ is 71 degrees.
As shown in the cross-section in FIG. 21, one of the alignment pins A extends through alignment apertures A, and in FIG. 22, the snap-fitting projection of one of the clips C extends through the aperture 80b. As also shown in FIG. 22, the direction D1 is inclined with respect to vertical by an angle θ of between 60 and 80 degrees. The direction D2 is inclined with respect to vertical by an angle that is equal to the angle α plus 90 degrees (the angle α is discussed above and shown in FIG. 1).
As is shown in FIGS. 21 and 22, when the exterior trim panel 14 is installed to the recess 66, sealing members S are used to reduce noise and water infiltration. More specifically, the sealing member S is located between the lower surface 70 of the recess 66 and the lower edge 88 of the exterior trim panel 14. Further, another one of the sealing member S is located between the upper surface 74 of the recess 66 and the upper edge 90 of the exterior trim panel 14. Hence, the exterior trim panel 15 is provided with the sealing members S (seals) that are positioned to contact the outboard surface 28a (an outboard facing surface) and the rearward facing surface 28b of the rear body panel 28, but are located within the recess 66.
The chrome trim member 108 attaches to the lower edge 88 of the exterior trim panel 14 providing a cosmetic accent to the overall appearance of the exterior trim panel 14. As shown in FIG. 12, the chrome trim member 108 has a closed end that aligns with the surface of the door jamb 60. Similarly, the front end 84 of the exterior trim panel 14 is closed aligning with the surface of the door jamb 60.
As shown in FIGS. 13-16, the chrome trim member 108 extends rearward from the front end 84 of the exterior trim panel 14 along the front section 96 and the middle section 98. However, in the depicted embodiment, the chrome trim member 108 ends just forward of the rear section 100 of the exterior trim panel 14. However, it should be understood from the drawings and the description herein that the chrome trim member 108 can be provided with a greater length in the vehicle longitudinal direction or can be completely eliminated. The inclusion and possible elimination of the chrome trim member 108 is a matter of cosmetic preference.
As shown in FIG. 12, the outboard facing surface 92 of the exterior trim panel 14 is flush with an adjacent section of the outboard facing surface 28a of the pillar portion 52 (above the recess 66). Further, as is also shown in FIG. 12 which shows an inboard direction I and an outboard direction O, the fender portion 54 (a lower section of the rear body panel 28) extends further outboard relative to the outboard surface 92 of the exterior trim panel 14.
In FIG. 5, relative dimensions of the exterior trim panel are identified. Specifically, an overall length L1 of the exterior trim panel 14 as measured along the vehicle body waistline W is shown. A first height L2 of the exterior trim panel 14 is measured adjacent to the rear end 86 of the exterior trim panel 14. Further, a maximum height L3 is measured in a vertical direction at the front end 84 of the exterior trim panel 14. As is clearly shown in FIG. 5, the overall length is several times greater than either of the first height L2 or the maximum height L3. Further, the overall length L1 of the exterior trim panel 14 more than five times the maximum height L3, and more than nine times the first height L2 in the depicted embodiment. However, it should be understood from the drawings and description herein that the ratios between the overall length L1, the first height L2, the maximum height L3 of the exterior trim panel 14 can be adjusted and altered. However, in the depicted embodiments, the overall length L1 of the exterior trim panel 14 is greater than the first height L2 and greater than the maximum height L3.
As shown in FIGS. 6 and 23, the rear end section 100 of the exterior trim panel 14 includes the rear end 86. The rear end 86 closes the inboard end of the exterior trim panel 14 while installed to the pillar portion 52 of the rear body panel 28. Further, an exposed outboard facing surface 112 of the rear window glass 44 faces the rear end 86 (the closed inboard end of the exterior trim panel 14).
The rear window glass 44 is installed to the rear window opening 34 in the absence of surrounding trim. In other words, at least the lateral edges, including the outboard facing surface 112, are exposed and or visible. Further, as mentioned above, the rear window glass 44 is provide with the non-transparent section 44b, which is darkened or black. Further the exterior trim panels 14 are darkened or black in appearance. In design configurations, such as those shown in FIGS. 6 and 23, there is a gap between the outboard facing surface 112 of the rear window glass 44 and the rear end 86 of the exterior trim panel 14. Therefore, as shown in FIGS. 6 and 23, a dark or black material 110 is provided on specific portions of a surface of rearward peripheral end 62 and the rear window supporting flange 64 of the pillar portion 52 of the rear body panel 28. The material 110 is dimensioned to align with the non-transparent section 44b of the rear window glass 44 and the rear section 100 of the exterior trim panel 14. In other words, the material 110 blackens space between the rear section 100 of the exterior trim panel 14 and the non-transparent section 44b (the black section) of the rear window glass 44. The material 110 can be a black tape or a black paint.
The black or dark lower portion of the non-transparent section 44b of the rear window glass 44, the black or dark material 110, the black or dark exterior trim panel 14, the black or dark non-transparent section 42c of the rear door 42, the black or dark trim panels covering the B-pillar 24 and the black or dark exterior surface of the A-pillars 22, along with the windshield of the vehicle 10 provide the roof structure 12 with a floating appearance. Under most lighting conditions, the lower portion of the non-transparent section 44b, the material 110, the exterior trim panels 14, the A-pillar 22, the B-pillar 24 and the non-transparent section 42c in the depicted embodiment are black, and appear to disappear making the roof structure 12 look as if it were separated from the remainder of the vehicle 10.
It should be understood from the drawings and the description herein that the vehicle 10, including the roof structure 12, the front door 40, the rear door 42, the trunk lid 46 and the fender portion 54 of the vehicle 10 are provided with a first exterior color while the lower portion of the non-transparent section 44b, the material 110, the exterior trim panel 14 and the non-transparent section 42c are all provided with generally the same dark second exterior color (for example, black), with the second exterior color being darker than the first exterior color. Consequently, the lower portion of the non-transparent section 44b, the material 110, the exterior trim panel 14 and the non-transparent section 42c define a uniform and dark colored stripe along an upper edge of the waistline W. This dark colored stripe provides the vehicle 10 with a floating roof appearance.
In the depicted first embodiment, the front section 96, the middle section 98 and the rear section 100 of the exterior trim panel 14 are formed as a continuous and single monolithic element, with no breaks or seams. In the first embodiment, the chrome trim member 108 is a separate element, but is provided as an accent and does not affect the floating roof appearance that is in part provided by the dark or black color of the outboard surface 92 of the exterior trim panel 14.
It should be understood from the drawings and the description herein that the vehicle 10 can include any of a variety of chrome trim elements that align with the chrome trim member 108. More specifically, the front door 40 and the rear door 42 can include chrome trim elements at the bottom of the forward side window 40a and the rearward side window 42a that combined with the chrome trim member 108, define a continuous chrome trim line that extends along the side of the vehicle 10, aligned with the vehicle body waistline W.
