Panel strip for sliding roof

Abstract

The invention provides a beading strip for an automobile sunroof that can be securely assembled on a sealing seat even if the molding size deviation occurs. The seam strip is composed of the following parts: a thick-walled base (2) embedded in the assembly groove (10) at the outer end of the sealing seat (9) fixed on the outer periphery of the roof glass; The connected hollow sealing part (3); it is integrated with the thick-walled substrate (2) and the hollow sealing part (3), and the upper flange (11) and the lower flange (11) formed by the upper and lower protrusions at the opening end of the assembly groove ( 12) The clamped thin-walled main body (5); the connection angles (θ) between the upper and lower surfaces of the above-mentioned thin-walled main body (5) and the hollow sealing part are respectively set to be less than 90°, and the upper side is defined as the direction from the hollow sealing part to the thicker part. The wall base is an ascending slope (6) that rises obliquely, and uses the lower surface as a descending slope (7) that descends obliquely.

Description

technical field [0001] The present invention relates to a beading strip provided for ensuring the sealing between a roof panel and a roof glass on a sunroof of an automobile. Background technique [0002] Referring to Figure 1 and figure 2 Be explained. In order to ensure the sealability between the roof panel 14 and the roof glass 15 on the car sunroof, the beading strip 20 is assembled in the sealing seat 9 fixed on the outer periphery of the roof glass 15 . This caulking strip 20 is composed of a thick-walled base 21 , a thin-walled main body 22 and a hollow sealing portion 23 . Moreover, there is an assembly groove 10 at the outer end of the sealing seat 9, and an upper flange 11 and a lower flange 12 are respectively formed up and down at the opening thereof. [0003] This crimping strip 20 makes the thick-walled substrate 21 embedded in the assembly groove 10 on the sealing seat 9, and its thin-walled main body 22 is assembled under the state of being clamped by the...

AI Technical Summary

Problems solved by technology

[0006] However, when there is a deviation in the molding size of the seam strip 20 or the sealing seat 9, the assembly state of the seam strip 20 relative to the seal seat 9 will become unstable, resulting in a problem of reduced sealing performance.

This problem occurs even on the linear assembly part S

Moreover, on the corner bending part C, since there is no good assembly method adapted to its curved shape, the problem of decreased sealing performance will be even greater
