Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door seal structure integrated with a door sash, which uses a door sash along a front pillar as a core material and is improved in connection with a door lower weather strip.

[0002]

2. Description of the Related Art Conventionally, when a sealing material to be attached to a door sash along a front pillar is connected to a door lower weather strip and continuously transferred from the former to the latter, a mold is formed at each of the transferred portions. The molds were placed on top of each other, and they were fastened to the door inner panel step by clips.

However, the former through the lower end of the sealing material attached to the door sash along the conventional front pillar and the upper end of the door lower weather strip attached to the step of the inner panel of the lower door, through the formers. The continuous transition from the latter to the latter requires two-piece mold-forming parts having a complicated shape, which not only increases the cost but also impairs the appearance and causes air leakage.

[0004]

The problems to be solved are the lower end portion of the sealing material attached to the door sash along the conventional front pillar and the upper end portion of the door lower weather strip attached to the step portion of the lower door inner panel. The continuous transition from the former to the latter through the mold forming parts respectively arranged in the above requires two mold forming parts having a complicated shape, which not only increases the cost but also impairs the appearance and winds. The present invention provides a door seal structure integrated with a door sash that solves the above-described problems.

[0005]

The present invention will be described with reference to the drawings. In the figure, a symbol is used in which one of the median lines descending from the apex angle of the isosceles triangle is painted, and the painted side represents a molded part, and the unpainted side represents an extruded part. . According to the first aspect of the present invention, there is provided a door sash as a core material and a sealing material integrated with the door sash, wherein the door sash 50 along the front pillar is a core material and the door sash 5 is provided.
The sealing member 10 integrated with the sealing member 10 is made of only an extruded product of a rubber-like elastic body, and is attached to the stepped portion of the lower door inner panel 60 and is connected to the upper end of the extruded portion 20 of the door lower weather strip. The plug-in connecting part 31 formed in the above is inserted into the lower end part of the hollow portion 15 of the sealing material 10 to be connected thereto, and the cover part 32 formed outside the plug-in connecting part 31 allows the plug-in connecting part 31 to be inserted. Together with this, the outer surface side of the lower end portion of the hollow portion 15 is sandwiched and covered.

According to the invention of claim 2, in addition to the structure of the invention of claim 1, in order to insert the clip 70 and attach it to the lower inner panel 60 of the door, the fin portion 33 of the molding portion 30 of the door lower weather strip is attached. Clip hole 34 provided
Is also used as a processing reference hole in the lower end portion of the sealing material 10.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Explaining an embodiment of the present invention, 10 is a sealing material having a door sash 50 as a core material and integrated with the door sash, which is made of only a rubber-like extruded product and has a hollow portion inside the vehicle. A main seal 11 having 15 and a grass run 12 and a sub-seal 13 are provided on the outside of the vehicle so as to be pressed against the front pillar 40 when the door is closed.

Reference numeral 20 denotes an extruded portion of the door lower weather strip, which is attached to the step portion of the door lower inner panel 60. Reference numeral 30 denotes a mold forming portion that is connected to the upper end portion of the extrusion forming portion 20, and is an insert connecting portion 31 that is inserted and connected to the lower end portion of the hollow portion 15, and the insert connecting portion 31.
A cover part 3 formed on the outer side of the cover part 3 for sandwiching and covering the outer surface side of the lower end part of the hollow part 15 together with the plug-in connecting part 31.
2 and the clip 70 are inserted, and the fin portion 33 provided with the clip hole 34 for attaching to the door lower inner panel 60 is integrally connected.

The plug connection portion 31 is hollow or semi-hollow.
Any solid material may be used, and different materials may be joined as long as they have the same function. Further, the plug-in connection portion 31 and the cover portion 32 are formed in a thin piece so that no gap is formed between the insertion connection portion 31 and the cover portion 32. Further, the plug-in connection portion 31 and the cover portion 32 are connected to the hollow portions 35 and 25 of the mold molding portion 30 and the extrusion molding portion 20, respectively. In addition, 36 is a reinforcing insert buried in the mounting side of the hollow portion 35 to the inner panel 60, 80 is an interior material, and 90 is a belt line outer weather strip.

[0010]

The sealing material 10 is made only of an extruded product, and is appropriately diagonally cut, notched, or subjected to rust-prevention treatment, so that a molding part is not required, which results in a significant cost reduction. Will be reduced. Further, since the door lower weather strip is joined to the die-molded portion 30 as described above, and particularly the hollow portion 15 is covered with the cover portion 32, air leakage is prevented, and the appearance is remarkably improved. Further, the clip hole 34 can be used as a processing reference hole in the lower end portion of the sealing material 10, and the rigidity of the mating portion is increased by embedding the reinforcing insert 36 in the mold forming portion 30. Alignment of the lower weather strip with the molding portion 30 is improved.

[0011]

Since the present invention is configured as described above,
There is no need to mold the front pillar portion of the door seal material 10 which is integral with the door sash, thereby significantly reducing the cost, preventing wind leakage, and significantly improving the appearance, and further, the seal material 10 and the door. The bondability between the lower weather strip and the mold forming portion 30 is improved.
