[Structure] A hollow seal portion 6a of a lower glass run 6 separate from the sub-seal 5 is provided at the lower end of the sub-seal 5 on the outside P side.
The downward lip 5a is provided along the surface of the outside P of the vehicle, and the inward lip 5b is branched from the downward lip 5a along the surface of the hollow seal portion 6a on the side of the horizontal flange 2a. When joining the extrusion-molded portion E and the mold-molded portion M at the corner portion Z, the downward lip 5a of the extrusion-molded portion E is extended to the branch portion Y and the corner portion Z, and the extended downward-facing lip 5a is used to form the mold-formed portion M. Is a seal structure that covers the outside from the outside as much as possible.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a seal structure including a combination of a main seal and a sub-seal that seal between a body opening edge and a door, and a glass run that seals between a window frame and a door glass, which are respectively attached to the inner and outer circumferences of a window frame. Is.

[Prior Art]

 In the symbols in the figure, there is a symbol in which half of the isosceles triangle that sandwiches the axis of symmetry is painted in black. The thick line of the extension line of the axis of symmetry represents the dividing line between the extrusion molding portion E and the molding portion M, Further, the white triangle side represents the extrusion molding portion E, and the black triangle side represents the molding portion M. As a conventional seal structure, as shown in FIGS. 1 to 5, a main seal 14 and a sub-seal 15 are integrally combined, and a combination of a glass run 16 which is a separate body from the combined body is used. As shown in FIG. 12, there are a sub seal 25 and a glass run 26 that are integrally connected, and a combination of a main seal 24 that is a separate body from the combined body.

However, in any of the above-described seal structures, the molding portion M is interposed in the branch portion Y and the corner portion Z. When this molded portion M is connected to the extruded portion E, the appearance of color, luster, connecting lines, etc. is uncomfortable and the appearance is impaired. The shape and connection line are devised so that the part is not exposed to the outside P side as much as possible, but the part S that is indicated by hatching such as the seal lip is still exposed, causing a feeling of strangeness and impairing the appearance. Points remain.

[0004]

[Problems to be solved by the device]

 The problem to be solved is that a considerable part of the molded portion M is exposed to the outside P side of the vehicle, causing a feeling of strangeness with the extruded portion E and impairing the appearance.

[0005]

Means for Solving the Problems An explanation will be given with reference to FIGS. 1 and 13 to 23. According to the present invention, the main seal 4, the sub seal 5, and the glass run 6, which seal between the window frame 2 and the door glass 3, doubly seal between the body opening edge 1 and the window frame 2, respectively, which are attached to the window frame 2. It has a combined seal structure, and in particular, a sub seal 5 on the outside P side of a sub seal 5 which is a body separate from the main seal 4 fitted in the upper portion of the window frame 2 and the horizontal flange 2a is separated from the sub seal 5. A downward lip 5a is provided along the surface of the hollow seal portion 6a of the lower glass run 6 of the body on the outside P side, and the downward lip 5a extends inward along the surface of the hollow seal portion 6a on the horizontal flange 2a side. The lip 5b is branched and the downward lip 5a of the extruded portion E is joined to the branched portion Y or the corner portion Z to join the extruded portion E and the die molded portion M together. Extended until the toner unit Z, the molded portion M in a downward lip 5a which is the extension in which as much as possible made by letting you cover from the outdoor side.

【Example】

 An embodiment will be described with reference to FIGS. 1 and 13 to 23. The seal structure of the present invention has a main seal 4, a sub seal 5, and a window frame that double seal between the body opening edge 1 and the window frame 2. It consists of a combination of glass runs 6 that seal between 2 and the door glass 3, and they are attached to the window frame 2, respectively, and are configured as follows.

That is, the main seal 4 is formed in a hollow shape and is attached to the outer periphery of the window frame 2 via the retainer 2b, and the sub-seal 5 and the glass run 6 below the sub-seal 5 are separate from the main seal 4. The sub-seal 5 is fitted into the upper portion of the window frame 2 and the horizontal flange 2a from above, and the glass run 6 is provided with an upper hollow seal portion 6a and a lower lip 6b. The retainer 2c is provided on the outer surface of the window frame 2. It is attached via a downward lip 5a along the outer side surface of the hollow seal portion 6a of the glass run 6, especially at the lower end of the sub seal 5 on the outside P side, and from the downward lip 5a to the hollow seal portion 6a. An inward lip 5b is branched along the surface of 6a on the side of the horizontal flange 2a. In addition, 5c is a lip projectingly provided on the sub-seal 5 and elastically contacts the drip molding 8. Reference numeral 7 denotes a hollow seal portion that elastically contacts the inner surface of the window frame 2 and is joined to the trim 7a fitted in the inner flange 1a of the opening edge 1 of the body. Q is indoor.

Further, when joining the extrusion molding portion E and the molding portion M at the branch portion Y and the corner portion Z, the downward lip 5a of the extrusion molding portion E of the sub-seal 5 is extended to the branch portion Y and the corner portion Z. The extended downward lip 5a covers the molded portion M 1 from the vehicle exterior P side as much as possible.

In addition, to specifically explain the embodiment at the corner portion, in order to make the mold-molded portion M as small as possible, the inner surface of the downward lip 5a is ground as shown in FIG. 23, or the outer surface of the glass run 6 is ground. Then, the seal lip S of the vertical portion V of the other party is made to lie under the inside of the downward lip 5a, and the end faces of the two extrusion molding portions E, E which intersect each other are butted and joined, or the seal of the vertical portion V is made. The end of the lip S is scraped and left discontinuous, or a molding portion M of about 1 mm is interposed.

[0010]

[Effect of the device]

 Since the present invention is configured as described above, the exposed outdoor portion of the molding portion M is minimized, the discomfort is remarkably alleviated, the appearance is improved, and the shape is simplified as compared with the conventional one. Cost is reduced.
