JPH08198032A - Wave dash preventing structure for glass roof weather strip - Google Patents

Abstract

PURPOSE: To provide a wave dash preventing structure for a glass roof weather strip which prevents waves from dashing against the corner sections. CONSTITUTION: In a weather strip mounted on the circumferential periphery of a glass roof 2 roughly in a square shape, a wrinkle absorbing dent 5 is formed in advance in the back face of a seal lip 4 projected to the inner circumferential side of the weather strip 3 abutting against the pane of glass 1 at the corner section of a glass roof 2, after the seal lip 4 has been bent along the corner section, molding material is poured in the dent 5 so as to be comprised of a corner section.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anti-waviness structure for weather strips for automobile glass roofs.

[0002]

2. Description of the Related Art As shown in FIGS. 4 and 5, a weather strip 9 attached to a peripheral edge of a substantially rectangular glass roof 2 of an automobile abuts against a roof panel 10 at a hollow portion on the outer peripheral side to seal the inner periphery. The side seal lip 11 abuts on the upper surface of the roof glass 1 on the glass support 12 to seal it.

[0003]

However, many wrinkles S are generated on the seal lip 11 at the corner portion of the glass roof 2, which causes inconvenience in sealing and appearance. Therefore, although the weather strip 9 was joined to the peculiar mold 13 shown in FIG. 6 and the peculiarity was applied by the press, there was a problem that the corrugation could not be sufficiently prevented. Therefore, in view of such conventional problems, the present invention,
An object of the present invention is to provide a structure for preventing waving of a weatherstrip for a glass roof, in which waving is prevented at the corners.

[0004]

In order to achieve the above object, the structure of the present invention is, as shown in FIG. 1, provided on the inner peripheral side of a weather strip 3 attached to the peripheral edge of a substantially square glass roof 2. A wrinkle absorbing recess 5 is previously formed on the back surface of the sealed lip 4, and the molding material 5a is formed in the recess 5 at least at the corner portion of the glass roof 2.
After the inflow, the corners are molded.

[0005]

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 shows a first embodiment of the present invention.
1 is the glass of the glass roof 2 shown in FIG. 4, 3 is a weather strip attached to the periphery of the glass roof 2, 4 is a sealing lip projecting on the inner peripheral side of the weather strip 3, and the tip of the glass roof 2 is It abuts the glass 1, and particularly shows the corner portion.

A wrinkle absorbing recess 5 having a U-shaped cross section is formed in advance on the back surface of the seal lip 4, and then it is bent and compressed by being fitted in upper and lower molds 6a and 6b for corners as shown in FIG. In addition, a molding material 5a such as synthetic rubber is filled in the depression 5 and molded. The corner seal lip 4 thus molded does not have wrinkles S as shown in FIG.

FIG. 3 shows a second embodiment of the present invention, in which a plurality of recesses 8 having a substantially semicircular cross section are formed in advance on the back surface of the seal lip 7 corresponding to the seal lip 4.
After that, the molding is performed in the same manner as in the first embodiment, and the corner portion of the seal lip 7 is not wrinkled.

[0008]

As described above, the corrugation preventing structure for a weatherstrip for a glass roof according to the present invention does not cause any wrinkles at the seal lips at the corners, which is different from the conventional one, and therefore the sealing property and appearance are improved. .
