In the automotive industry, it is desirous to have moveable windows which are '10 flush with the vehicle body roof, door and side pillars. This flushness, while providing an aesthetic appearance also provides aerodynamic characteristics and reduces drag. When providing moveable windows that are peripherally flush with the vehicle body, the sealing of the windows must be taken into consideration. In J a peripheral or four-sided flush moveable window system, the weather stripping is substantially behind or on the interior of the window concealed from view from the outside of the vehicle.

Weather stripping currently utilized by the automotive industry for moveable windows has a U-shaped glass run channel. The U-shaped channel sandwiches the window periphery between the legs and web of the U-shaped channel to retain and seal the window. These types of glass run channel systems also have a portion of the weather stripping or a molding on the exterior or outside of the window.

Accordingly, the present invention provides the art with a weather stripping system for moveable vehicle windows which enables the windows to be peripherally flush with the vehicle body, at least in preferred embodiments. The present invention provides the art with a weather stripping system that is substantially concealed from view in a closed position.

Further understanding of the present invention will be had from the following description of the preferred embodiments taken in conjunction with the attached drawings and the appended claims.

i sheet metal of the doors 12 and 13, roof 16 and the side and mirror panels 18 and 19.

The weather stripping gasket assembly 30 is adapted to be secured about an opening in the vehicle 10. The weather stripping gasket assembly 30 is generally comprised of four separate and distinct portions forming the gasket system The portions are side pillar members 32 and 34, top header member 36 and bottom member 38. The.side members 32 and 34, top member 36 and bottom member 38 may be integrally formed as a single unit or may be positioned individually onto the vehicle The side members 32 and 34 are substantially identical and the followi.ng -discussion will relate to both. Turning to Figure 4, a cross-section view of the side pillar members 32 and 34 is illustrated. The side pillar member weather strip 32, 34 includes 'a metallic reinforcement member 40 surrounded by an integral elastomeric skin 41. In cross-section, the reinforcement member 40 includes a first U-shaped channel 42 having elastomeric fingers 44 extending from skin 41 into the interior of the channel 42. The fingers 44 secure the weather stripping 32, 34 onto a flange 46 about the opening on the vehicle A second U-shaped channel 48 of the reinforcement member 40, positioned transverse to the first U-shaped channel 42, is adapted to receive a member 50 secured to the window 14. The second U-shaped channel 48 generally has a pair of fingers 52 and 54 projecting from the skin 41 into the channel 48 to sealably contact member 50, as seen in Figure 4. A =r

C. 4 4 1 I C C C #4* 4 1 III-YU -~-IIL sealing flange 56 extends from the skin 41 at the end of one of the legs 55 of the U-shaped channel 48 to enhance the seal of the weather stripping 32, 34 with the vehicle opening.

The member 50 is ordinarily elastomeric and adhesively secured or the like to the windows 14 and 15. The member is generally T-shaped or L-shaped, having its vertical tail received in the U-shaped channel 48 of the weather stripping 32, 34. A second elastomeric T-shaped member 62 is adhesively secured to the side panel 18 or the mirror panel 19, as seen in Figures 3 and 4. The T-shaped member 62 includes a member 68 which forms a portion of the peripheral bead 20. The vertical tail 70 of the T-shaped member 62 abuts the vehicle opening and is contacted by the sealing flange 56 to provide further sealing of the windows 14 and 15 with the vehicle body.

Moving to Figure 5, a cross-section view of the top header member 36 is shown. The top header member 36 includes a U-shaped channel 72. The U-shaped channel 72 includes a metallic U-shaped reinforcement member 74 surrounded by an integral elastomeric skin 76. Fingers 78 project from the 'skin 76 into the interior of the U-shaped channel 72 to secure aS* the U-shaped channel 72 onto the flange 80. The leg 82 of the 1 U-shaped channel 72 includes at its terminus, an angularly extending portion 84. The portion 4 includes a member 86 integrally formed with skin 76 which forms a portion of the peripheral bead A resilient and deflectable member 88 extends from the skin 76 at the junction of leg 82 and web 83. The member 88 moves from a first position where the member abuts the skin on leg 82 when the window is in a closed position, as seen in Figure 5, to a second position when the window is rolled down, as seen in phantom in Figure 5. In the second position, a channel 90 is formed between the leg 82 and the member 88.

The channel 90 serves as a drip channel to remove precipitation, water or the like.

Turning to Figure 6, a cross-section view of the bottom member 38 is illustrated. The bottom member 38 includes a retention member 92 having a metallic U-shaped reinforcement member 94. An integral skin 96 surrounds the U-shaped reinforcement member 94. The skin 96 includes a thickened or belly portion 98 on one of the legs 100 and the web 102 of the U-shaped reinforcement member 94. The belly portion 98 includes member 104 at its tip 106. The member 104 forms a portion of the peripheral bead A wiping member 108 extends from the belly portion 98 t adjacent the free extending end of leg 100. The wiping member i &tit 108 cleans precipitation, water or the like from the windows S when the windows move to a down and then up position within the doors 14 and 15. The wiping member 108 is deflectable and 4 moves from an angled resting position with respect to the 'belly portion 98, as seen in Figure 6, to a position substantially parallel to the door flange, as seen in phantom in Figure 6, to enable the window 14 to be moved to a down position. The wiping member 108 reflexes to its original position to enable the flocking 110 on the wiping member 108 6.to contact the window 14 when the window moves to its up pos~ition.

The window 14 includes a member 112 adhesively secured to the interior of the bottom of window 14, as seen in Figure 6. The member 112 has an overall 'IT" shape with a flange 114 extending from the horizontal portion of the The T-shaped member 112 is rotated 90' when attached to the window so that the vertical tail 116 is in a horizontal plane. The flange 114 seals the member 112 with the belly portion 98 of the bottom member 38, as seen in Figure 6. The tail 116 of the 'IT" member 112 seals the window 114 with a sealing member 118 on the interior of the door.

The sealing member 118 also has an overall 'IT" shape.

One portion 119 of Chfe horizontal member 120 of the 'IT" is in sealing contact with the tail member 116 of the member 112, as seen in Figure 6. The vertical portion 122 of the T-shaped seal member 118 includes a metallic U-shaped reinforcement member 124. The reinforcement member 124 is surrounded by an integral skin 126 which forms the vertical 122 and horizontal 4*120 portions of *the The reinforcement member 124 surrounds a flange 128 to retain the seal member 118 onto the door panel, as seen in Figure 6. The second portion 130 of the horizontal member of the 'IT" is in sealing contact with the interior trim panel 132 of the door 16.

4 t The above-described system is generally used on a hard f top type vehicle. The hard top vehicles enable the window members 50, and thus the windows 14 and 15, to be removed from the U-shaped receiving channels 48 of side members 32 and 34 -7 L

when the doors 12 and 13 are opened. Thus, the windows 14 and would extend freely from the doors 12 and 13 when the doors 12 and 13 are open.

A clip mechanism 134 is utilized to retain the windows 14 and 15 in a sealed position when the doors 12 and 13 are closed. Turning to Figures 7 and 8, a pin 136 is illustrated traversing the U-shaped channel 48 of the side member 32 near the junction of the side member 32 and top member 36. A cutout portion 138 is formed in the T-shaped member 50 at its upper end. The cutout portion 138 includes a tail 140 at the free extending end of the member 50. The tail 140 resiliently deflects to enable the tail 140 to be positioned behind the pin 136 when the window is in a closed position, as seen in Figure 7. The tail 140 deflects, enabling the window 14 to be moved away from the pin 136 when the door is opened and deflects upon returning to its first position, as seen in phantom in Figure 7. Also, as the vehicle travels, the pin S4r4 "*41 S 136 retains the tail 140 in position so that the window does i, not blow out or move away from a sealing contact with channel 48 during travel of the vehicle. Alternatively, tail 140 can be a rigid member which is adjusted into position by a camming a t up action during door closure.

Turning to Figures 9-15, other embodiments of the present invention are shown. Identical elements are designated with the same reference numerals.

In a vehicle where a free standing frame or the like is deslired about the window 14 an embodiment like that of Figure 9 may be utilized. When an integral frame is used, the bottom i -8member 38 would remain the same as that previously discussed.

The top member 36 will remain substantially the same, however, a frame, like that described below, will be included instead of a flange attachment. The side members are different.

Turning to Figure 9, a cross-section of a side member with an integral frame is shown.

The side members 142 include a metallic frame 144 surrounded by an integral elastomeric skin 146. The frame 144 may have varying types of configurations, generally including a U-shaped channel 148. The U-shaped channel 148 includes a pair of fingers 150 and 152 projecting from the skin 146 into the channel 148. The channel 148 also includes a guide way 154 adjacent to its web 156. The guide way 154' retains the window member 158 within the channel 148. A door bulb seal 160 is integrally formed with the skin 146 to enable the frame to be sealed against a door opening of the vehicle.

i i The window member 158 is of an shape, having one of its horizontal portions 157 positioned in the guide way 154 to I retain the window members 158 within the channel 148. Thus, {I the window member 158 will not pull out of the U-shaped i( channel 148 and the window 14 remains in sealing contact with I the gasket.

Another embodiment of a side member of the present invention is illustrated in Figures 10 and 11. The cross-sectional views illustrate a U-shaped channel similar to those previously described. The U-shaped channel 161 includes a reinforcement member 162 and an integral skin 164. A member for retaining the U-shaped channel 161 to a flange or an 9 integral frame may be combined with the U-shaped channel 161.

Also, a magnetic system like that disclosed in applicants' U.S. Patent APr?__--n-ir 1,qq 9 entitled "Magnetic Window Seal Assembly", P4-= he r -cepeo nt-pplication the specification of which is herein incorporated by reference, may be used to retain the channels onto the flange.

The channel 161 includes a pair of fingers 166 and 168 extending from the skin 164 into the channel 161. The fingers 166 and 168 have stops 170 and 172 at their terminus. The stops 170 and 172 are elongated and are positioned substantially parallel with the legs 174 and 176 of the U-shaped reinforcement member 162 when the window member 178 or 179 is retained in the U-shaped channel 161.

In the embodiment of Figure 10, an I-shaped member 178 is adhesively secured to the window 14. One of the horizontal portions 180 of the is retained behind the stops 170 and S. 172. Also, the fingers 166 and 168 and stops 170 and 172 would enable the member to be removed from the channel if this type of system is utilized in a hard top system like that of Figure 4. In the embodiment of Figure 11, a T-shaped window member 179 is shown. Both embodiments may be utilized with S either the hard top or integral frame systems.

Figure 12 illustrates a cross-section view of another embodiment of a bottom member of the gasket assembly. The bottom member 182 includes a reinforcement member 184 surrounded by an integral elastomeric skin 186. The skin 186 jincludes an enlarged belly portion 188 projecting from one SRA 7 0- 1$o^4, i4 a O b side of the reinforcement member 184. A wiping member 190 also projects from the same side as the belly portion 188.

A The wiping member 190 is formed from a flocked mylar material.

The wiping member 190 moves from a first position when the w.'dow is closed to a second position when the window is open.

In the first position, the wiping member 190 is positioned adjacent to the belly member 188 sandwiched between the member 192 and the belly member 188. As the window is opened, the K wiping member 190 moves away from the belly member 188. As the window moves down into the door, the wiping member 190 deflects to a position substantially parallel with the outer sheet metal of the door. Once the window has reached its all the way down position within the door, the wiping member 190 moves to a position above the window, as seen in Figure 12.

The member 192 has a first leg 194 which sandwiches the j wiping member 190 against the belly member 188. Also, a i channel 1F6 enables the window 14 to be secured onto the .j member 192. A second leg member 198 extends from the member 192 to contact with the T-shaped member 200. The T-shaped sealing member 200 functions substantially the same as ii S" T-shaped member 118 previously described herein.
