Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a glass run for guiding a window glass of a vehicle such as an automobile, and more particularly to the structure of a glass run extending in the direction of movement of the glass.

A conventional glass run has a cross-sectional shape, for example, as shown in FIG. That is, the base of a frame-shaped door sash 2 located approximately on the same plane as the door main body 1 is fixed to the upper part of the door body 1 shown in FIG. Glass run 3 is held. This glass run 3
is made into a U-shaped cross section consisting of a central side 3a and both sides 3b, 3c continuous at right angles to both ends of this central side 3a, and these side sides 3b, 3
The end portion 4a of the door glass 4 is received between the ends 4a and 4c. The glass run 3 includes a pair of seal lips 3d whose bases are integrally molded at the tips of the above-mentioned side sides 3b and 3c and which are folded back to wrap around the corresponding side sides 3b and 3c. ，
3e, and is structured to seal between the outer surfaces of these seal lips 3d, 3e and the surface of the door glass 4 (see, for example, the 6th edition of the New Automobile Engineering Handbook, published by the Society of Automotive Engineers of Japan). However, although the glass run 3 having such a structure is relatively sufficient to maintain watertightness and airtightness between it and the door glass 4, the surface of the door glass 4 and the outer surface of the seal lip 3e are Due to the discontinuous surface, wind separation occurs during driving. That is, since the air flow during the vehicle is in the state shown by the arrow in FIG. A is generated, and this vortex a generates noise.

In order to prevent noise as described above, the present invention extends a seal lip connected to the tip of the outside side of the glass run toward the center of the glass so that the tip of the seal lip comes into contact with the surface of the window glass. It is proposed that the outer surface of the seal lip be smoothly continuous with the outer surface of the side portion exposed to the outside of the vehicle or the outer surface of the window frame.

Embodiments of the present invention will now be described in detail with reference to FIGS. 3 and 4.

FIG. 3 is an embodiment in which the glass run 10 of the present invention is applied to the rear side door sash of a front door, and the base of the door sash 12 extending substantially vertically is fixed to the upper part of the door body 11. door sash 12
The first holding part 12a has a "C" shape with the opening facing the rear of the door body 11, and the first holding part 12a has a "C" shape with the opening facing the front of the door body 11. The second holding part 12b is placed back to back to the first holding part 12a, and a molding part 12c connects the outside of the vehicle of these holding parts 12a and 12b. A base portion 13a of a weather strip 13 extending along the outer circumference of the door sash 12 is fitted into the first holding portion 12a, and a main seal portion 13b of the weather strip 13 is fitted into the first holding portion 12a.
is tightly sealed to the outer surface of the center pillar (not shown).

Further, the door main body 11 includes a door sash 12.
A door glass 14 is provided which is located in the same plane as the above and which can be raised and lowered in the direction of the arrow Y, and an end portion 14a of the door glass 14 is received in a glass run 10 fitted into the second holding portion 12b. A glass run 10 extending along the inner circumference of the door sash 12
is made of an elastic material such as rubber and has a U-shaped cross section, and has a central side portion 10a whose inner surface faces the end surface of the door glass 14. A pair of side portions 10b and 10c extending substantially parallel to the inner and outer surfaces of the door glass 14 are provided at both ends of the central side portion 10a.
are arranged in series, and the door glass 14 is sealed by the flocks 15 on the inner surfaces of these side portions 10b, 10c and the inner surface of the central side portion 10a.

According to the present invention, the both sides 10b, 10c
Seal lips 16A, 16B extending in substantially the same direction as these are integrally molded at the tips.
These seal lips 16A, 16B are given flexibility by being sufficiently thinner than the side portions 10b, 10c, and the tip portion 16
a is brought into line contact with the inner and outer surfaces of the door glass 14.
The outer surface 17 of the seal lip 16B is connected to the tip portion 16a and the molding portion 12c of the door sash 12.
It is considered to be a slope that gently connects the two. In FIG. 3, reference numeral 18 is a waist weather strip that seals between the outer panel of the door body 11 and the door glass 14. In the illustrated example, the weather strip 18 bonded to the molding 19 is attached to the glass run. It is molded separately from 10.

Since the embodiment shown in FIG. 3 has the above-described structure, when the door body 11 is viewed from above, the amount of protrusion of the glass run 10 from the outer surface of the door glass 14 can be made much smaller than in the conventional case. At the same time, since the outer surface of the door glass 14 and the molding part 12c of the door sash 12 are loosely connected to the outer surface 17 of the seal lip 16B, the air flowing along the outer surface of the door glass 14 flows to the outer surface 17 of the seal lip 16B. It flows smoothly along the imaginary line as shown by the arrow. This eliminates the occurrence of noise caused by eddying at the glass run position, which is the case in the prior art.

FIG. 4 shows a second embodiment of the present invention, in which a door sash 12 has a "C"-shaped first holding part 12a with an opening facing toward the rear of the door body 11, and a first holding part 12a with an opening facing toward the rear of the door body 11. A second holding part 12b formed in a "C" shape facing forward and placed back to back to the first holding part 12a communicates with the outside of the vehicle of these holding parts 12a and 12b. It is provided with a molding part 12c. Said first holding part 1
A base portion 13a of a weather strip 13 extending along the outer circumference of the door sash 12 is fitted into the base portion 2a, and a main seal portion 13b of the weather strip 13 closely fits and seals the outer surface of a center pillar (not shown).

Further, the door main body 11 includes a door sash 12.
A door glass 14 is provided which is located in the same plane as the door glass 14 and can be raised and lowered in the direction of the arrow Y, and an end portion 14a of the door glass 14 is received in a glass run 10A fitted into the second holding portion 12b. A glass run 1 extending along the inner circumference of the door sash 12
0A is formed from an elastic material such as rubber into a U-shaped cross section, and has a central side portion 10a whose inner surface faces the end surface of the door glass 14. A pair of side portions 10b extending substantially parallel to the inner and outer surfaces of the door glass 14 are provided at both ends of the central side portion 10a.
10c are connected, and these side parts 10b, 10
The door glass 14 is sealed by the flocking 15 on the inner surface of c and the inner surface of the central side portion 10a.

Seal lips 16A, which extend in substantially the same direction as the side portions 10b and 10c, are provided at the ends of the side portions 10b and 10c.
16B is integrally molded. These seal lips 16A, 16B are attached to the side portions 10b, 10c.
By making the thickness sufficiently thin compared to the above, flexibility is provided, and the tip 16a is brought into line contact with the inner and outer surfaces of the door glass 14. The outer surface 21 of the seal lip 16B is an inclined surface that gently connects the tip portion 16a and the molding portion 12c of the door sash 12. In addition, in Fig. 4, the code 1
8A is a waist weather strip that seals between the outer panel of the door body 11 and the door glass 14. The embodiment shown in FIG. 4 is characterized by a slot 20 formed in the glass run 10A to be fitted into the second holding portion 12b of the door sash 12, and a waist sealing between the outer panel of the door body 11 and the door glass 14. The weather strip 18A is integrally molded on the lower end of the glass run 10A. Therefore, in this embodiment, the outer surface 17A of the seal lip 16B is connected to the side portion 10c.
By making it continuous with the outer surface 21 of the glass run 10A, in addition to obtaining the same effect as in the case of FIG. 3, the end treatment of the glass run 10A can be simplified and the sealing effect can be enhanced.

As is clear from the above, the glass run of the present invention is suitable for a structure in which the receiving end of the window glass moves in the length direction of the glass run, so it can be used in addition to the rear side of the front door as described above. It can also be applied to the front and rear sashes of the rear door or to parts other than the door. In addition, in the above two embodiments, the seal lips on both the outside and outside of the vehicle were extended toward the center of the window glass, but they were applied only to the outside of the vehicle.
The inside of the vehicle may be folded back toward the edge of the glass as usual.

In conclusion, according to the present invention, the amount of protrusion of the glass run protruding from the outer surface of the window glass to the outside of the vehicle can be reduced compared to the conventional glass run having a seal lip that is folded back so as to wrap between the side parts. The air flowing along the window glass can be guided into a laminar flow state by the outer surface of the seal lip.
It is possible to provide a glass run that does not generate eddies or noise.
