Abstract

PURPOSE:To make a weather strip look more attractive and reduce the whistling noise, by increasing the wall thickness and making it come close to the car outer side of a retainer, owing to a projecting part integrally joined to the rear side surface of a hollow sealing part even if it is deformed when a glass door is closed and it is pressed to a seal surface of this hollow sealing part. CONSTITUTION:A retainer 20 is installed at the car outer side of a center pillar 10 of a hard top car, and in this constitution, it is equipped with a weather strip 40 sealing each space between door glass 35 and quarter glass 50 olus the center pillar 10. In a state that a door is closed, when the opened door glass 35 is closed, a rear end of the door glass 35 is guided by a hollow part 42 and a front lip 43 and shifted to the car outer side along a path P. A projecting part 47 is integrally joined to a surface at the rear side of a rear side R of a hollow seal 44, increasing the extent of wall thickness in this rear side R and also making it come close to a surface at the car outer side of the retainer 20. Therefore, any deformation in the rear side R of the hollow seal part 44 is checked, so that a rear lip 45 and the glass 50 are elastically made contact with each other, and thus there is no clearance produced.

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 for a hard top vehicle.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 1 to 3, a weather strip 40 for a hard top vehicle which is attached to a center pillar 10 through a retainer 20 and seals between a door glass 35 and the center pillar 10, The following configurations are used.

That is, 41 is a base portion fitted into the retainer 20, 42 is a hollow portion integrally connected to the base portion 41, and 43 is a front end of the hollow portion 42 and a front lip projecting to the outside of the vehicle. When the door glass 35 is raised from the lower position and closed in the state where the door 30 is closed, the rear end surface of the door glass 35 is guided to the outside of the vehicle along the locus P by being guided by the hollow portion 42 and the front lip 43. Move to position Z. Reference numeral 44 denotes a hollow seal portion that is integrally connected to the rear portion of the hollow portion 42 and to the outer surface of the vehicle and seals the space between the center pillar 10 and the door glass 35, and 45 projects rearward at the rear end of the vehicle outer portion. A rear lip that seals between the center pillar 10 and the quarter glass 50 with
6 is a flange 11 projecting from the front end of the center pillar 10.
The inner lip is elastically brought into contact with the U-shaped trim 60 fitted on the inner wall of the hollow portion 42, and is projectingly provided on the front end of the hollow portion 42 and on the inner side of the vehicle. Reference numeral 61 is a cored bar embedded in the trim 60.

However, in the above-mentioned conventional weather strip 40, the door glass 35 is lifted and closed, as shown in FIG.
When the rear end of the door glass 35 is pressed against the sealing surface of the hollow seal part 44, the rear side R of the hollow seal part 44 is deformed and the rear lip 45 and the front end of the quarter glass 50 are shown at position Z. There is a problem that a gap S is generated between them and the appearance is deteriorated and wind noise is increased. Further, in order to solve this problem, if the portion R on the rear side of the hollow seal portion 44 is changed to hard rubber, another problem that the cost rises is produced as a by-product, and the rear side of the hollow seal portion 44 is also increased. If the wall thickness of the entire portion R is increased to the door glass side, another problem that the compressive load increases when the door glass rises occurs.

[0005]

In the conventional weather strip 40, when the door glass 35 is raised and closed, the rear side portion R of the hollow seal portion 44 is deformed and the rear portion of the rear weather strip 40 is deformed. A gap S is formed between the lip 45 and the front end of the quarter glass 50, and the appearance is deteriorated and wind noise is increased. In order to eliminate this, the rear side portion R of the hollow seal portion 44 is changed to hard rubber. However, if the thickness of the door glass is increased or the thickness is increased, the cost is increased, and another problem that a compressive load is increased when the door glass is lifted is by-produced.

[0006]

[Means for Solving the Problems] FIGS. 1, 4, 5 and 6
-It will be described with reference to FIG. The hollow portion 4 is provided in the base portion 41 that is fitted to the retainer 20 attached to the center pillar 10.
2 are integrally connected, and a hollow seal portion 44 that seals between the center pillar 10 and the door glass 35 is integrally connected to the rear portion of the hollow portion 42 and the outer surface of the vehicle. Center pillar 10 at the rear end facing backward
Rear lip 4 that seals between the glass and the quarter glass 50
5 is a weather strip for a hard-top vehicle in which the hollow seal portion 44 has a rear side R, and
After that, the thickness of the side portion R is increased, and the convex portion 47 that is brought into close contact with the outer surface of the retainer 20 is integrally connected.

[0007]

When the door glass 35 is closed and the rear end portion of the door glass 35 is deformed when pressed at the sealing surface of the hollow seal portion 44, the rear surface of the rear side portion R of the hollow seal portion 44 is deformed. With the convex portion 47 integrally connected to the hollow seal portion 44
Since the thickness of the rear side portion R is increased and is brought into close contact with the surface of the retainer 20 on the vehicle outer side, the rear side portion R of the hollow seal portion 44 is
The rearward deformation is suppressed, the rear lip 45 and the quarter glass 50 make elastic contact with each other, and no gap is formed between them, so that the appearance is improved and wind noise is reduced. Moreover, the cross-sectional shape change for exhibiting the above-mentioned effect is extremely small, and the increase in cost and the increase in the compressive load when the door glass rises are almost the same (which is considerably cheaper than the case where the rear side portion R is made of hard rubber). ).
