Window weatherseal with molded weatherstrip
View Patent ↗The invention concerns the field of window seals to be encased in a frame, in general a motor vehicle door frame. The seal is intended to be in contact with part of the perimeter of a window and comprises a guide slot strip consisting of two upward segments and an upper segment, and a sealing strip extending between a low part of one of said upward segments and a high part of the other of said upward segments. The sealing strip is molded in a single piece and comprises an upward curved part, and is attached at least at its upper end to one of the upward segments of the guide slot strip.
1. Window seal to be encased in a frame, configured to be in contact with part of the perimeter of a window, and comprising an extruded guide slot strip including two upward segments and an upper segment, and a sealing strip extending between a low part of one of said upward segments and a high part of the other of said upward segments, wherein said sealing strip comprises an upward curved part and a substantially horizontal extending part, and in that said sealing strip is attached at least at its upper end to one of said upward segments of the guide slot strip;
wherein the upward curved part and the substantially horizontal extending part are bi-injected into a mold and form the sealing strip as a single piece without a distinct transition between the upward curved part and the substantially horizontal extending part, while also defining in said sealing strip at least a rigid part and a flexible part which are distinct.
2. Seal according to claim 1 , wherein said rigid part comprises means for holding on said frame.
3. Seal according to claim 2 , wherein an upper portion of said flexible part covers the upper edge of said rigid part.
4. Seal according to claim 3 , wherein a lower portion of said flexible part extends downwards so that the edge of said frame to which said rigid part is intended to be fixed is situated between a lower portion of said rigid part and said lower portion of said flexible part.
5. Seal according to claim 3 , wherein said rigid part is made from rigid plastic and said flexible part is made from elastomer or thermoplastic.
6. Seal according to claim 3 , wherein the junction between said sealing strip and one of said upward segments of the guide slot strip is situated close to said upper segment of the guide slot strip.
7. Seal according to claim 2 , wherein a lower portion of said flexible part extends downwards so that the edge of said frame to which said rigid part is intended to be fixed is situated between a lower portion of said rigid part and said lower portion of said flexible part.
8. Seal according to claim 7 , wherein said rigid part is made from rigid plastic and said flexible part is made from elastomer or thermoplastic.
9. Seal according to claim 2 , wherein said rigid part is made from rigid plastic and said flexible part is made from elastomer or thermoplastic.
10. Seal according to claim 2 , wherein the junction between said sealing strip and one of said upward segments of the guide slot strip is situated close to said upper segment of the guide slot strip.
11. Seal according to claim 1 , wherein said rigid part is made from rigid plastic and said flexible part is made from elastomer or thermoplastic.
12. Seal according to claim 1 , wherein the junction between said sealing strip and one of said upward segments of the guide slot strip is situated close to said upper segment of the guide slot strip.
13. Seal according to claim 1 , at least part of the length of said sealing strip is provided with a slippery coating.
14. Seal according to claim 13 , wherein said slippery coating is a flocked profile.
15. Seal according to claim 13 , wherein said slippery coating is added on to said sealing strip.
16. Seal according to claim 13 , wherein said slippery coating is fixed to said sealing strip.
17. Seal according to claim 13 , wherein said slippery coating is located on a lip.
18. Seal according to claim 1 , wherein the junction between said sealing strip and one of said upward segments of the guide slot strip is situated close to said upper segment of the guide slot strip.
19. Seal according to claim 1 , wherein the sealing strip is a single component.
20. Seal according to claim 1 , wherein the sealing strip is an integrally formed combination of a rigid portion along a length of the sealing strip and a flexible portion along a length of the sealing strip.
21. Seal according to claim 1 , wherein the sealing strip is a single component defined by an integral combination of a rigid portion and a flexible portion, the rigid and flexible portion extending along the entire length of the sealing strip.
22. Seal according to claim 1 , wherein the flexible part and the rigid part are integrally formed and integrally connected.
