Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a weather strip for automobile doors.

[0002]

2. Description of the Related Art As shown in FIGS. 3 and 4, for example, in a peripheral portion of a rear door D of an automobile, a door hinge H is provided when the door is closed.
The weather strip W attached along the first peripheral edge D ₁ and the second peripheral edge D ₂ having different approach angles depending on the distance from the extrusion molded portions W ₁ , W ₂ having different cross-sectional shapes.
And a molding portion W ₃ interposed therebetween.

[0003]

However, the appearance is impaired because a connecting line caused by a difference in material appears between the mold forming portion W ₃ and the two extrusion forming portions W ₁ and W _{2 on} the surface of the lip portion. There is a problem. As a countermeasure, a method may be considered in which the molding portion W ₃ is omitted and a weather strip having the same cross section is provided through the first and second peripheral portions D ₁ and D ₂ , but the sealing function of the hollow seal portion T is insufficient. There is a problem that becomes. In view of the conventional problems, it is therefore an object of the present invention to provide a weather strip for doors that improves the appearance without impairing the sealing function.

[0004]

In order to achieve the above object, the structure of the present invention is, as shown in FIGS. 1 and 2, a state of separation from the door hinge H when the door is closed in the peripheral portion of the automobile door D. In the weather strip W for doors attached along the first peripheral edge D ₁ , the second peripheral edge D ₂ and the third peripheral edge D ₃ which are adjacent to each other at different entrance angles,
The door weather strip W is a mounting base portion 1 is fitted in succession with the same cross-sectional shape in the door sash S of the first to third peripheral portion D ₁ to D _3, the first peripheral portion the fitting recess 2 of the mounting base portion 1 at a position corresponding to the D _1, first with a hollow sealing portion 3b formed to conform to the periphery D ₁ of the first is fitted the base portion 3a 1 seal body 3
When, in the fitting recess 2 of the mounting base portion 1 in the position corresponding to the peripheral portion D ₂ of the second, which is shaped to conform to the periphery D ₂ of the second is fitted the base portion 4a Hollow seal part 4
a second seal body 4 provided with b, and the third peripheral portion D
_In the fitting concave portion 2 of the mounting base portion 1 at the position corresponding to ₃ ,
The third seal main body 5 is provided with a hollow seal portion 5b fitted to the base portion 5a and adapted to fit the _third peripheral edge portion D3.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. In FIG. 1, reference numeral 1 denotes a mounting base portion of a weather strip W fitted into a door sash S, which forms a base portion 1a extruded and fitted into the door sash S, a fitting recess 2 and a sub-lip portion 1b, The vehicle door D shown in FIG. 2 has the same cross-sectional shape that is continuous along the first peripheral edge D ₁ , the second peripheral edge D ₂ and the third peripheral edge D ₃ . 3
Is a first seal main body, which is extruded to form a base portion 3a which is fitted into the fitting recess 2 of the mounting base portion 1 at a position corresponding to the _first peripheral edge portion D1. , A hollow seal portion 3b which is formed so as to fit the first peripheral edge portion D ₁ , that is, the hollow seal portion 3b which is the most fit on the seal, is provided.

Reference numeral 4 denotes a second seal main body, which is extruded and formed on the base portion 4a which is fitted into the fitting concave portion 2 of the mounting base portion 1 at a position corresponding to the _second peripheral edge portion D 2. Perimeter D
A hollow seal portion 4b formed so as to conform to ₂ is projected. Reference numeral 5 denotes a third seal main body, which is extruded and fitted into the fitting recess 2 of the mounting base portion 1 at a position corresponding to the _third peripheral edge D ₃ and is provided with the first peripheral edge D. ₁
The hollow seal portion and the hollow sealing portion 3b formed to fit is formed to conform to the second circumferential portion D ₂ to 4
Hollow seal portion 5 formed so as to gradually change the shape difference from b
b is protruding.

That is, the weather strip W of the present invention is
Since the first seal main body 3, the second seal main body 4, and the third seal main body 5 are attached to the attachment base portion 1 while being fitted in the fitting recesses 2, the door hinge H is closed when the door is closed.
First peripheral portion D having different approach angles depending on the distance from
₁ , the second peripheral portion D ₂ and the third peripheral portion D ₃ are always in the most suitable state in terms of sealing. In addition, the first to third
The extruded mounting base portion 1 is attached through the peripheral edge portions D _{1 to} D ₃ of the same, and the extruded first to third seal main bodies 3 to 5 are also fitted thereto.
Unlike the conventional case, since molding members having different textures are not interposed, the connecting line does not appear on the lip portion when the door is closed, and the appearance is not deteriorated.

[0008]

As described above, in the door weather strip of the present invention, the first seal body to the third seal body are fitted in the fitting recesses of the mounting base portion, so that when the door is closed, Even in the peripheral portion where the approach angle is different depending on the distance from the door hinge, the first to third seal bodies are always brought into close contact with the opening portion of the vehicle body in an optimum state to improve the sealing property, and the conventional mold forming member is interposed. The appearance of the connecting line does not appear and the appearance is not spoiled.
