Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a window weather strip that is fitted to the edge of a window opening such as a triangular window of an automobile, and seals the interior and exterior of the vehicle in close contact with the window glass.

Examples of conventional window weather strips include those shown in FIGS. 1 and 2.

Reference numeral 1 designates a weather strip for windows, which includes a mounting base 3 having a substantially U-shaped cross section that is fitted onto a flange 2 at the edge of a window opening of the vehicle body, and a window glass side 3a of the mounting base 3.
A main seal lip 5 is formed incidentally on the window glass 4 and seals the interior and exterior of the vehicle interior by coming into close contact with the interior side 4a of the window glass 4 when the window glass 4 is closed, and the main seal lip 5 extends to the lower end 3c of the mounting base 3b on the window glass side. , the flange portion 2
A sub-seal lip 7 that comes into close contact with the vehicle body panel 6 when fitted is integrally molded.

However, in the case of such a window weather strip 1, since the V-shaped groove 8 is formed between the window glass side 3a of the mounting base 3 and the main seal lip 5, the V-shaped groove 8 is free from dust. It has the disadvantage that it easily accumulates and is difficult to clean. Also,
When painting or flocking the surface of the mounting base 3,
There was a problem that it was difficult to clearly indicate the parting line for painting, etc., and the workability of painting, etc. was poor. Furthermore, the main seal lip 5 as shown in Fig. 2 is easily deformed and has a weak repulsive force, so in order to increase the repulsive force, improve the sealing performance, and prevent the intrusion of rainwater, etc., the main seal lip 5 must be Although it is conceivable to make the root portion 5a thicker, this method has the problem of increased costs.

The present invention has been developed in view of the above-mentioned conventional circumstances, and includes a sub-rip on the window glass side of the mounting base that extends toward the main seal lip so as to come into contact with the main seal lip when the window glass is closed. It is an object of the present invention to provide a weather strip for windows in which the above-mentioned problems are solved by forming a protruding sub-rip on the main seal lip when the window glass is closed.

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.

Fig. 3 shows an embodiment of the window weather strip of the present invention, in which 1 is the weather strip, 2 is a flange portion at the edge of a window opening on the vehicle body, and 3 is a flange portion 2.
A mounting base having a substantially U-shaped cross section fitted into the mounting base,
A main seal lip 5 is integrally provided at the end of the window glass 3a of the mounting base 3. This main seal lip 5 includes a projecting piece 5c that projects obliquely from the end of the window glass side 3a toward the window glass 4, and
The protruding piece 5c includes a bent piece 5e that is bent and inclined outward toward the window glass 4 from the top 5a, and has a substantially horizontal contact piece 5d at its tip that contacts the window glass 4. In addition, the top portion 3d of the mounting base 3
The window glass 4 is placed on the side of the window glass 3a nearby.
A sub-rip 11 is formed to protrude and come into contact with the side surface of the top 5a of the protrusion piece 5c when the cover is closed.

This sub-rip 11 is formed so as to come into contact with the main seal lip 5 and close the V-shaped groove 8 when the window glass 4 is closed.

Further, from the viewpoint of sealing performance, it is more preferable that the sub-rip 11 is formed protruding from the window glass side 3a of the mounting base 3 between the top 5a and the bottom end 5b of the main seal lip 5.

As a result of forming as described above, when the window glass 4 is closed, the sub-rip 11 comes into contact with the main seal lip 5 and closes the V-shaped groove 8, so deformation of the main seal lip 5 is suppressed and the Since the repulsive force of the main seal lip 5 is improved, the main seal lip 5 more effectively comes into close contact with the interior side 4a of the window glass 4.

As is clear from the above description, this invention has a main seal lip that is integrally formed on the window glass side end of the mounting base with a protruding piece that projects obliquely from the side end of the mounting base toward the window glass. and a bent piece that is bent and inclined outward from the top of the protruding piece toward the glass side and has a substantially horizontal contact piece at its tip that comes into contact with the window glass; A sub-rip is formed protrudingly on the side near the window so that it comes into contact with the top side surface of the protruding piece when the window glass is closed. Of course, the upward rotation of the protruding piece on the mounting base is reliably prevented, and the rear end of the bent piece is perpendicular to the window glass when it hits the side surface of the top of the protruding piece of the sub-rip. Since it will be pressed in the direction, it will be approximately horizontal (perpendicular to the glass)
The contact piece is pressed vertically through the bent piece. Therefore, the repulsive force of the main seal lip becomes strong, and the main seal lip and the window glass come into close contact with each other to ensure sufficient sealing performance. Moreover, when the window is opened, the tip of the sub-rip is separated from the top side of the protruding piece, so when the window is closed, the bent piece rises slightly perpendicularly to the window glass due to the gap. This results in an increased vertical repulsive force of the folded piece against the window glass. Therefore, the contact piece of the main seal lip and the window glass come into even closer contact.

Therefore, the sealing performance of the weather strip is greatly improved, and the infiltration of rainwater and the like into the vehicle interior is more effectively prevented. Further, since dust and the like are prevented from entering the V-shaped groove, the effort of cleaning the V-shaped groove can be saved. Furthermore, by using the base and tip of the subrip as the parting line for painting or flocking, the parting line becomes clear.
It has an excellent practical effect of improving the workability of painting and flocking.
