Constant seal gaps for removable vehicle panels
View Patent ↗A vehicle roof water runoff management system is provided with an improved seal that has a constant seal gap between removable vehicle roof top panels and an adjoining fixed roof. The constant seal gap is maintained in the B-pillar interface area with the vehicle's roofing components. The vehicle roof water runoff management system offers improved manufacture and long term performance reliability over previous designs.
1. A vehicle removable roof system comprising:
a vehicle fixed roof having a first finished surface panel joined to a first structural panel, where said first structural panel is configured with a mounting flange, said mounting flange having a first horizontal portion and a downward slope portion extending from said first horizontal portion toward a junction with a B-pillar of said vehicle;
one or more removable top panels, where each of said removable top panels have a second finished surface joined to a second structural panel, where said second structural panel is configured to engage said mounting flange of said vehicle fixed roof; and
a contoured dropped flange extending downward from said second structural panel toward the junction with the B-pillar to form a constant gap between said mounting flange of said first structural panel and said second structural panel in both the first horizontal portion and the downward slope portion.
2. The system of claim 1 further comprising a weather strip positioned in said constant gap along said first horizontal portion and said downward slope portion.
3. The system of claim 1 wherein said first structural panel and said second structural panel are formed of sheet molding composition (SMC).
4. The system of claim 1 wherein said first structural panel and said second structural panel are formed of bulk molding composition (BMC).
5. The system of claim 1 wherein said first structural panel mounts to a vehicle frame.
6. The system of claim 2 wherein said weather strip is compressed with an even downward pressure.
7. The system of claim 1 further comprising a 2-way locating pin on said first structural panel for interlocking with a locating receptacle of said one or more removable top panels.
8. The system of claim 1 wherein said dropped bond flange supports rib area.
9. A vehicle removable roof system comprising:
a vehicle fixed roof having a first finished surface panel joined to a first structural panel, where said first structural panel is configured with a mounting flange, said mounting flange having a first horizontal portion and a downward slope portion extending from said first horizontal portion toward a junction with a B-pillar of said vehicle;
one or more removable top panels, where each of said removable top panels have a second finished surface joined to a second structural panel, where said second structural panel is configured to engage said mounting flange of said vehicle fixed roof;
a contoured dropped bond flange extending downward from said second structural panel toward the junction with the B-pillar to form a constant gap between said mounting flange of said first structural panel and said second structural panel in both the first horizontal portion and the downward slope portion; and
a weather strip positioned in said constant gap, where said weather strip is compressed with an even downward pressure.
10. The system of claim 9 wherein said first structural panel and said second structural panel are formed of sheet molding composition (SMC).
11. The system of claim 9 wherein said first structural panel and said second structural panel are formed of bulk molding composition (BMC).
12. The system of claim 9 wherein said first structural panel mounts to a vehicle frame.
13. The system of claim 9 further comprising a 2-way locating pin on said first structural panel for interlocking with a locating receptacle of said one or more removable top panels.
14. The system of claim 9 wherein said dropped bond flange supports rib area.
