Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a weather strip mounted between an automobile sunroof and a vehicle body panel.

2. Description of the Related Art Regarding the above weather strip, for example, the actual development of Sho 61-20
Japanese Patent No. 5815 discloses the configuration shown in FIG.
In the figure, 1 is a vehicle body side panel, 3 is a sunroof lid, and a sunroof weather strip 5 is interposed between them. The weather strip 5 mainly includes a welt 5a having a substantially U-shaped cross section, and a hollow seal lip 5b fixed to a wall surface of the welt 5a on the vehicle body side panel 1 side. A core material 7 is embedded in the welt 5a, and lips 5c, 5c for holding the flange 3a of the sunroof lid 3 are projectingly provided on the inner wall surface of the welt 5a.

By thus fitting the flange portion 3a of the sunroof lid 3 into the welt 5a of the weather strip 5, the hollow seal lip 5b of the weather strip 5 is elastically contacted with the vehicle body side panel 1 when the sunroof lid 3 is closed. The airtightness inside and outside the vehicle can be maintained.

However, in the case of such a conventional sunroof weather strip, when the sunroof lid 3 is tilted up and tilted down, the hollow seal lip 5b elastically contacting the vehicle body side panel 1 is irregularly deformed. There is a problem in that it is easily induced to cause a poor appearance.

For example, when the sunroof lid 3 is tilted down as shown by the arrow A, the sliding resistance between the hollow seal lip 5b that is in elastic contact with the vehicle body side panel 1 and the vehicle body side panel 1 when the flange portion 3a descends is reduced. Due to the hollow seal lip 5b
Of the hollow seal lip 5b is deformed so that the substantially central part of the hollow seal lip 5b rises, and the hollow seal lip 5b projects upward from the vehicle body side panel 1. It is easy to get stuck.

That is, when the lid 3 is tilted down, the hollow seal lip
The sliding resistance of 5b cannot be dealt with instantly, resulting in the above-mentioned deformation, resulting in poor appearance.

Therefore, the present invention solves the problem that such a conventional sunroof weather strip has, and that the hollow seal lip elastically contacting the vehicle body side panel is deformed irregularly when the sunroof lid is tilted down. Prevent
It is an object of the present invention to provide a weather strip that can maintain a good appearance.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention mainly comprises a welt having a substantially U-shaped cross section and a hollow seal lip fixed to the wall surface of the welt on the vehicle body side panel side. In the weather strip inserted between the vehicle body side panel and the sunroof lid, a stopper of a predetermined length for holding an appropriate hardness is projected on the outer wall surface of the welt on the vehicle body side panel side, and the hollow seal is provided. The sunroof weather strip has a projection integrally formed with the hollow seal lip on the inner wall surface of the lip, which projects toward the lower side of the stopper projecting on the outer wall surface of the welt.

According to this structure, when the sunroof lid is tilted down, a deforming force that rises upward acts on the hollow seal lip elastically contacting the vehicle body side panel, but at this time, the hollow seal lip is projected on the inner wall surface of the hollow seal lip. The protrusion abuts against a stopper provided on the outer wall surface of the welt, and the movement of the hollow seal leap is restricted by the stopper, so that excessive deformation of the hollow seal lip is prevented.

Therefore, the hollow seal lip does not project above the vehicle body side panel, and it is possible to maintain a good appearance.

EXAMPLES An example of a sunroof weather strip according to the present invention will be described in detail below by assigning the same reference numerals to the same components as those of the conventional configuration.

In the configuration shown in FIG. 1, 1 is a vehicle body side panel, 3 is a sunroof lid, and a sunroof weather strip 5 is interposed between them, as in the conventional example.
The weather strip 5 is mainly composed of a welt 5a having a substantially U-shaped cross section and a hollow seal lip 5b fixed to a wall surface of the welt 5a on the vehicle body side panel 1 side. Welt 5a is made of a material with appropriate hardness,
The hollow seal lip 5b is made of a soft material such as sponge rubber. A core material 7 is embedded in the welt 5a, and a plurality of lips 5c, 5c for holding the flange portion 3a of the sunroof lid 3 are projectingly provided on the inner wall surface of the welt 5a. .

On the other hand, on the outer wall surface of the vehicle body side panel 1 side of the welt 5a, a stopper 10 having a predetermined length is provided so as to project toward the vehicle body side panel 1, and the inner wall surface of the hollow seal lip 5b is further provided. Has a protrusion integrated with the hollow seal lip 5b.
Reference numeral 11 is provided so as to project toward the welt 5a and toward the lower side of the stopper 10.

The stopper 10 and the protrusion 11 are the weather strips 5.
May be provided so as to project entirely along the longitudinal direction of the above, or may be arranged at appropriate intervals along the longitudinal direction of the weather strip 5.

By disposing a core material similar to the core material 7 embedded in the welt 5a inside the stopper 10,
The strength of 10 can be further increased. In this case, the core material 7 in the welt 5a may be partially extended into the stopper 10.

According to this structure, when the flange portion 3a of the lid 3 for the sunroof is lowered in the direction of arrow A in order to tilt down the sunroof lid 3 from the state shown in FIG. 1, as shown in FIG. 5 hollow seal lip 5b
And the vehicle body side panel 1 slide, and the hollow seal lip 5b
As shown by the arrow C, the hollow seal lip 5b is deformed upwardly by a deforming force. According to the present invention, even when such a force is exerted, as shown in FIG. Since the projection 11 projecting from the inner wall surface of the hollow seal lip 5b abuts against the stopper 10 projecting from the outer wall surface of the welt 5a, the deformation of the hollow seal lip 5b is limited by the stopper 10.

In other words, the hollow seal lip 5b and the vehicle body side panel 1 are
When the flange portion 3a of the sunroof lid 3 descends, it comes into contact with the sliding portion while maintaining a specific sliding resistance. Therefore, in the conventional example, the hollow seal lip 5b cannot respond instantly and causes irregular deformation. According to the present invention, excessive deformation of the hollow seal lip 5b can be prevented based on the collision between the protrusion 11 on the hollow seal lip 5b side and the stopper 10 on the welt 5a side.

Therefore, the hollow seal lip 5b does not project above the vehicle body-side panel 1 and the appearance can be maintained in a good condition.

Further, when the sunroof lid 3 is closed, the flange portion 3a is sealed by the lips 5c, 5c provided on the inner wall surface of the welt 5a, so that the airtightness inside and outside the vehicle can be favorably maintained.

Effects of the Invention As described in detail above, according to the weather strip for a sunroof of the present invention, a welt having a substantially U-shaped cross section and a hollow seal lip fixed to the wall surface of the welt on the vehicle body side panel side are provided. In a weather strip that is configured as a main body and is inserted between a vehicle body side panel and a sunroof lid, a stopper of a predetermined length that holds appropriate hardness is projected on the outer wall surface of the welt on the vehicle body side panel side. Since the projection is formed on the inner wall surface of the hollow seal lip toward the lower side of the stopper projecting on the outer wall surface of the welt, the weather strip for sunroof is configured as follows. The action and effect described in (1) are brought about. That is, when the sunroof lid is tilted down, a deforming force that rises upward acts on the hollow seal lip that elastically contacts the vehicle body side panel, but even in such a case, the protrusions protruding from the inner wall surface of the hollow seal lip Can contact the stopper provided on the outer peripheral surface of the welt to limit the movement of the hollow seal lip. Therefore, the hollow seal lip is prevented from being excessively deformed, and the hollow seal lip does not project above the vehicle body side panel, so that the appearance of the vehicle can be favorably maintained.
