Description

BACKLITE SYSTEM FOR USE IN AN AUTOMOTIVE VEHICLE CONVERTIBLE ROOF
BACKGROUND AND SUMMARY OF THE INVENTION
This invention relates generally to automotive vehicles and more particularly to a window system for use in an automotive vehicle convertible roof.
Soft top convertible roofs in automotive vehicles have commonly employed flexible, polyvinyl chloride back windows, which are also known as backlites. Flexible, polymeric backlites are often preferred over glass windows since they tend to maximize the size of the backlite opening thereby improving rear visibility. The flexible, polymeric material allows for an enlarged window opening since it is less expensive to manufacture, lighter weight and typically easier to stow as compared to rigid, glass windows. An example of such a flexible, polymeric backlite is disclosed in U.S. Patent No. 5,271 ,655 entitled
"Window Which can be Fastened in a Folding Top by Means of a Zipper, and a Process for Exchanging a Surface Section" which issued to Ball et al. on
December 21 , 1993.
However, flexible, polymeric backlites often suffer from undesired permanent kinking, distortion or wrinkling when stowed or fully retracted. This can lead to poor window aesthetics and premature cracking of the backlite during use.
In accordance with the present invention, a preferred embodiment of an apparatus for use in automotive vehicle convertible roofs includes an elongated tensioning member being disposed adjacent to an edge of a window. In a further aspect of the present invention, at least a portion of the tensioning member is disposed in an elastomeric sealing member. In yet a further aspect of the present invention, a pair of resilient tensioning members are disposed adjacent to top and bottom edges of a backlite for deterring crosscar folding of the backlite while allowing fore and aft folding of the backlite when retracted. In still another aspect of the present invention, a first end of an elastic strap is attached to a movable roof bow while an opposite end is attached to the roof covering material adjacent to a corner of the backlite. The backlite system of the present invention is advantageous over conventional devices since the present invention tensioning members encourage the upper and lower sections of the backlite to stay tensioned or taut during folding thereby deterring kinking, distortion or wrinkling. In addition, it has been found that the elastic straps of the present invention apply a diagonal tensioning load to the backlite to further cause the backlite to remain taut while being folded. Furthermore, the present invention backlite system is aesthetically pleasing by hiding the tensioning members from view while providing an easy to assemble, low cost and lightweight backlite tensioning assembly. The present invention provides superior tensioning performance while greatly enhancing the durability and quality of a flexible backlite. Additional advantages and features of the present invention will become apparent from the following description and appended claims, taken in conjunction with the accompanying drawings.

Figure 6 is a cross sectional view, taken along line 6-6 of Figure 5, showing the alternate embodiment of the backlite system.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Figures 1 and 2 show the preferred embodiment of a backlite system employed in a convertible roof assembly 11 of an automotive vehicle 13 of the present invention. Convertible roof assembly 11 includes a linkage or top stack mechanism covered by a pliable fabric top covering 15. More specifically, the linkage assembly includes a number one roof bow 17, a number two roof bow 19, a number three roof bow 21 , a number four roof bow 23, and a number five or rearmost roof bow 25. Convertible roof assembly 11 is movable from a raised and extended position covering the vehicle's passenger compartment, as is shown in Figure 1 , to a fully retracted and stowed position within a boot or storage area, as is shown in Figure 4.
Referring now to Figures 1-3, a flexible backlite window 31 is attached to a rear panel of fabric covering 15 by way of an extruded sealing profile 33. Backlite 31 is preferably made from a sheet of polyvinyl chloride polymer. Sealing profile 33 is preferably extruded from a synthetic elastomeric polymer, such as Santoprene which can be purchased from Monsanto Co. Sealing profile 33 has a generally C-like cross sectional shape defined by a flat leg 35 and a rounded section 37. An access slot 39 and circular cross sectionally shaped cavity 41 are also disposed in sealing profile 33. Backlite 31 is dielectrically bonded or sewn to leg 35 of sealing profile 33. A backlite opening edge of fabric covering 15 is inserted into slot 39 and then fabric covering 15 is dielectrically bonded or sewn to leg 35 of sealing profile 33. Sealing profile 33 has a uniform cross sectional shape and extends around the complete peripheral edge 43 of backlite 31.
An elongated, upper tensioning rod 51 is inserted into the corresponding cavity 41 of sealing profile 33 prior to insertion of fabric covering 15. Tensioning rod 51 is made from a spring stainless steel material having a circular cross sectional shape. Ends 53 of upper tensioning rod 51 terminate at the tangent to the radius at each upper corner of sealing profile 33. Similarly, a lower tensioning rod 55 is disposed in a lower portion of sealing profile 33 adjacent to a bottom edge of backlite 31. Both tensioning rods 51 and 55 project in a generally horizontal and crosscar direction. Tensioning rods 51 and 55 are somewhat resilient and springy. As is shown in Figure 1 , a stretchable elastic strap 61 has a first end 63 riveted to number three bow 21. A second and opposite end 65 of elastic strap 61 is sewn to an inside surface of fabric covering 15 adjacent to an upper corner 67 of backlite 31. A second elastic strap is symmetrically disposed adjacent to the opposite corner of backlite 31. Alternately, elastic strap 61 may have its first end 63 fastened to number four bow 23.
As is shown in Figures 1 , 2 and 4, tensioning rods 51 and 55 ensure that the upper and lower sections of backlite 31 remain tensioned and taut during folding to deter permanent creasing, kinking, distortion and wrinkling. Thus, tensioning rods 51 and 55 generally prevent undesired folding of backlite 31 in the crosscar direction while allowing backlite 31 to fold about its middle in a fore and aft direction when the top stack is retracted in an accordion manner. In addition, elastic straps 61 apply a diagonal tensioning or pulling load on backlite 31 to cause backlite tensioning and tautness while being folded. An alternate embodiment of the backlite system of the present invention is illustrated in Figures 5 and 6. This alternate embodiment is similar to the preferred embodiment except that rectangularly cross sectionally shaped aluminum tensioning bars 81 are retained within fabric pockets 83 above and below upper and lower peripheral edges of backlite 31. The lower tensioning bar is longer in a crosscar direction than is the upper tensioning bar and extends slightly past bottom corners of the backlite. Pocket 83 consists of two layers of fabric sewn or dielectrically bonded to each other and to the inside surface of fabric covering 15. After insertion of tensioning bar 81, the ends of each pocket are sewn or bonded shut. For this embodiment, a conventional C-shaped sealing profile and zipper-type arrangement can be employed, such as that disclosed in U.S. Patent No. 5,271 ,655.
While various embodiments of the backlite system of the present invention have been disclosed, it will be appreciated that various other constructions may be employed without departing from the present invention. For example, while the vertical peripheral edges of the disclosed backlite embodiments are shown free of a tensioning rod or bar, partial vertically extending side tensioning members may be employed as long as they allow for fore and aft folding of the backlite when stowed. Additionally, other fiberglass, polymeric or composite tensioning members may be used. It is also envisioned that various alternate top stack linkage mechanisms and roof bow arrangements can be incorporated with the tensioning member features of the present invention. Various materials have been disclosed in an exemplary fashion, however, other materials may of course be employed. It is intended by the following claims to cover these and any other departures from the disclosed embodiments which fall within the true spirit of this invention.
