Abstract

(57) [Abstract] [Purpose] To provide a weatherproof strip for a sunroof, which has excellent sealing properties and produces a low wind noise. A weather strip to be attached to a sunroof having a tilt-up / down mechanism, wherein a body panel 10 is provided on an upper portion of a base 31 having a U-shaped cross section fitted to a glass 20.
An outer seal lip 35 that covers the edge of the body, and an inner seal lip 35 that makes elastic contact with the vertical surface of the edge of the body panel 10 at the lower part of the base 31 and the outer seal lip 35. A bridge 37 is hung between the inner surface of the above and the inner seal lip 36.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a weather strip mounted on a sunroof having a tilt up / down mechanism.

[0002]

2. Description of the Related Art Conventionally, as a conventional example of a weather strip attached to a sunroof having a tilt-up / down mechanism, an end of the body panel 10 is attached to a base portion 31 having a U-shaped cross section fitted to a glass 20 as shown in FIGS. A hollow seal portion 32 that is elastically contacted with the edge corner and is integrally joined,
Alternatively, as shown in FIGS. 4 and 5, a cross section U similar to the above-mentioned conventional example.
An outer seal lip 35 that covers the edge of the body panel 10 is integrally formed on the upper portion of the base 31 while the hollow seal 32 that elastically contacts the edge corner of the body panel 10 is integrally connected only to the lower portion of the character-shaped base 31. It is used by projecting.

However, of the above conventional weather strips for sunroofs, the former shown in FIG. 1 usually has a wrap amount of 2 to 2.5 mm with the body panel 10,
If the amount of wrap is insufficient due to variations on the body panel 10 side (size of window hole for sunroof), variations in the size of the glass 20, variations in the position when the vehicle is assembled, variations in the shape of the weather strip 30, etc. As shown in FIG. 3, if water leaks W from the gap between the body panel 10 and the weather strip 30 or if the wrap amount is too large, the hollow seal portion 32 sticks out to the outside of the vehicle and the appearance is damaged. There is a problem. The latter shown in FIG. 4 improves the sealing performance only by adding the outer seal lip 35, but if the wrap amount is too large, the outer seal lip 35 is lifted as shown in FIG.
There is a problem in that a gap S is formed between 0 and 0, and the wind noise increases when the wind T is received during traveling.

[0004]

The problem to be solved is that the conventional weather strip for sunroof described above is
Due to variations in the body panel 10 side, the size of the glass 20, the position at the time of assembling the vehicle, the shape of the weather strip 30, etc., water leakage or conversely, the hollow seal portion 32 sticks out to the outside of the vehicle, impairing the appearance, Further, if the outer seal lip is lifted and wind is received during traveling, the wind noise may increase.

[0005]

Means for Solving the Problems An explanation will be given with reference to FIGS. 6 to 8. The present invention is a weather strip to be attached to a sunroof having a tilt-up / down mechanism, in which an outer seal lip 35 that covers an end edge portion of the body panel 10 is projectingly provided on an upper portion of a U-shaped base 31 that is fitted to the glass 20. Then, an inner seal lip 36, which makes elastic contact with the vertical edge of the edge of the body panel 10, is provided at the bottom of the base portion 31, and a bridge 37 is provided between the inner surface of the outer seal lip 35 and the inner seal lip 36. It is built up.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment will be described. 10 is a body panel, 20 is a glass for a sunroof having a tilt-up / down mechanism fitted in a window hole for a sunroof opened in the body panel 10, and 30 is an end of the glass 20. A weather strip to be attached to the edge, which is constructed as follows. Reference numeral 31 is a cross section U made of solid rubber fitted to the glass 20.
It is a letter-shaped base. Reference numeral 35 denotes an outer seal lip made of solid rubber that integrally projects from the upper portion of the base portion 31 and covers the edge portion of the body panel 10. , 36 are sponge rubber inner seal lips that are integrally provided on the lower part of the base portion 31 and are elastically brought into contact with the vertical edges of the end edges of the body panel 10.
Reference numeral 37 denotes a sponge rubber bridge which is hung between the inner surface of the outer seal lip 35 and the inner seal lip 36. It should be noted that the bridge 37 may be flat or may have a curved surface concave toward the body panel 10.

The operation will be described. When the glass 20 is closed, the inner seal lip 36 is closed by the body panel 1.
0 is elastically contacted with the vertical plane of the edge portion of 0, and the bent inner seal lip 36 wraps around the bridge 37 as shown in FIG.
It is attracted to the edge portion of 0 to prevent its bouncing (lifting), and together with the inner seal lip 36, the body panel 10
The double sealing between the glass and the glass 20 significantly improves the sealing property and reduces wind noise during high-speed traveling.

[0008]

Since the present invention is constructed as described above,
Since the body panel 10 and the glass 20 are double-sealed, the sealing performance is significantly improved and the wind noise during high-speed traveling is reduced.
