Description

Description: FIELD OF THE INVENTION The present invention relates to a glass run of automobile windshield glass.

2. Description of the Related Art Generally, an automobile door has a vehicle body opening 1 shown in FIG.
3 installed on the periphery of the door 2 attached to the
In addition, a structure is known in which a weather strip that is in close contact with the vehicle body opening edge portion 1a when the door is closed is mounted, and a glass run is formed in which a fitting portion with which the peripheral edge portion of the window glass 4 is slidably contacted is formed when the window is closed. ing. For example, as shown in FIG. 4 as a cross-sectional view taken along the line IV-IV in FIG. 4, the bent portion 5a of the retainer 5 is fitted inside the door sash 3 while the window glass 4 is closed when the window is closed. The base portion 6a of the grass run 6 into which the peripheral edge portion 4a is fitted is fitted and fixed. The glass run 6 is formed with a vehicle exterior seal lip 6b and a vehicle interior seal lip 6c that come into contact with the windshield 4, and an outer wall surface 6d of the glass run 6 has a plurality of seal lids that come into contact with the inner wall surface 3a of the door sash 3. 6e, 6f and 6g are formed. When attention is paid to the seal lip 6g, the tip portion 6h is in contact with the inner wall surface 3a of the door sash 3 in a state of facing the vehicle outer side, so that the sealing property between the glass run 6 and the door sash 3 is enhanced.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in the case of such a conventional glass run structure of window glass, the seal lip 6g abutting against the inner wall surface 3a of the door sash 3 is fitted into the door sash 3 when the glass run 6 is fitted into the door sash 3. Since it is erected in the direction perpendicular to the wall surface 3a, there is a problem that the reaction force caused by the seal lip 6g becomes large and the workability of assembling is impaired. That is, when the glass run 6 is fitted into the door sash 3 as shown in FIG. 5, when the glass run 6 is gripped with a hand as shown in the drawing, the tip portion of the seal lip 6g.
Since 6h rises in a vertical direction, that is, in a direction in which it abuts the inner wall surface 3a of the door sash 3 substantially vertically, the reaction force of the seal lip 6g increases when the glass run 6 is fitted, and the assembling property deteriorates. Will result in.

Therefore, the present invention solves the problems that the conventional glass run of the windshield has, improves the assembling property of the glass run to the door sash, and further the sealing property between the seal lip of the glass run and the inner wall surface of the door sash. It provides a grass run structure that can enhance the

Means for Solving the Problems In a vehicle door sash, a plurality of seal lips that come into contact with the inner wall surface of the door sash are formed on the outer wall surface, and a fitting portion with which the peripheral edge of the window glass slides is formed on the inner wall surface. In the configuration equipped with the glass run, among the plurality of seal lips formed on the outer wall surface of the glass run,
At least one seal lip is formed to be longer than the other seal lips, and the seal lip is located above the outer wall surface on the inside of the vehicle and at a predetermined angle with the insertion direction of the grass run when the grass run is fitted and fixed to the door sash. It has a glass run configuration that is erected so as to incline toward the inside of the vehicle.

Action When inserting the grass run into the door touch, the seal lip that is erected upward from the outer wall surface corresponding to the inside of the grass run upwards longer than the other seal lip is directed toward the inside of the car by a predetermined angle with the inserting direction of the grass run. Since the slant is slanted, the reaction force of the long seal lip does not increase even when the grass run is fitted into the door sash, and smooth assembly work can be performed. The force of elastic contact with the wall is urged,
This brings about the effect of increasing the sealing force between the grass run and the door sash.

Embodiment Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings by giving the same reference numerals to the same portions as those of the conventional configuration.

FIG. 1 shows a bent portion 5a of the retainer 5 inside the door 3
Insert and fix, then add 6 glass run to this door 3
3 shows a state before the base portion 6a of FIG. The glass run 6 is formed with a vehicle exterior seal lip 6b and a vehicle interior seal lip 6c which come into contact with the windshield 4, and the door run 3
Seal lips 6e, 6f, 6g are formed to abut the inner wall surface 3a. This seal lip 6g is compatible with other seal lips 6e, 6f
The seal lip 6g is formed longer than the outer wall surface 6d corresponding to the inner side of the glass run 6 and the insertion direction A of the glass run 6 when the glass run 6 is fitted and fixed to the door sash 3. And is erected toward the inside of the vehicle in a direction inclined by a predetermined angle, in the illustrated example, inclined by an angle θ.

According to this structure, when the operator grips the glass run 6 as shown in the figure and fits it into the door sash 3, the seal lip 6g formed longer than the other seal lips 6e and 6f is placed inside the vehicle. By inclining by the angle θ, a large reaction force due to the seal lip 6g is not generated, and the assembling work can be performed extremely smoothly. Further, as shown in FIG. 2, after the assembly of the glass run, the grip force of the operator is lost, and the inner seal lip 6c and the outer seal lip 6b spread in a direction in which they are separated from each other, which is accompanied by a long length. A restoring force in the counterclockwise direction shown in the drawing is applied to the seal lip 6g. As shown in FIG. 2, the restoring force is further increased by fitting the window glass 5 while sliding the glass run 6 after the assembling, and as a result, the close contact between the long seal lip 6g of the glass run 6 and the door sash 3 is made. The effect of improving the sealing property and perfecting the sealing property is provided.

EFFECTS OF THE INVENTION As described in detail above, the glass run of the windshield for an automobile according to the present invention has a plurality of seals formed on the outer wall surface of the glass run in which the fitting portion with which the peripheral edge portion of the wind glass is slidably contacted is formed on the inner wall surface. Forming at least one of the lips longer than the other lips,
Since the seal lip is erected upward from the outer wall surface on the inner side of the vehicle and inclined toward the inner side of the vehicle at a predetermined angle with respect to the inserting direction of the glass run when the glass run is fitted and fixed to the door sash, the glass run is This has the great advantage of preventing an increase in the reaction force due to the long seal lip when assembling the door sash, and improving the workability of the assembly. Further, after the glass run is assembled and when the peripheral portion of the windshield is slidably fitted to the glass run, the elastic contact force with respect to the inner wall surface of the door sash due to the restoring force of the long seal lip causes the grass run and the door sash to be separated. The sealing force is increased, and the effect of being able to further improve the sealing performance inside and outside the door when the window is closed is exhibited.
