Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a seal structure along a roof side of an automobile.

[0002]

[Prior Art]

 In the sashless door vehicle as shown in FIG. 4, the roof side 1 extending from the front pillar 1a to the roof side edge 1b and the quarter pillar 1c is along the roof side 1 and the outer peripheries of the door glasses 2A and 2B. A seal structure is formed to seal the gap between them.

FIG. 5 shows a typical example thereof. A weather strip 3D is attached to the roof side 1, and a flange 11 protruding substantially at a right angle from the roof side 1 has a U-shaped cross section which is an in-vehicle member. 5 is fitted. The weather strip 3D includes a hollow seal portion 32 against which the outer periphery of the door glass 2A is pressed when the door is closed, and is fitted to the retainer 7 fixed to the roof side 1 with a grommet screw 8. A lip 34 is formed at the vehicle-inside end of the weather strip 3D so that the tip of the weather strip 3D abuts on the trim 5 and seals the gap between the weather strip 3D and the trim 5.

[0004]

[Problems to be solved by the device]

 By the way, in this type of seal structure, if it is used for many years, the weather strip 3D may be displaced in whole or in part with respect to the retainer 7, or may be partly displaced from the retainer 7 to affect the sealability. ..

In addition, the door glass 2A generally has an upper portion that gradually falls toward the inside of the vehicle when it is raised and closed, and the upper portion pushes the weather strip 3D into the vehicle. The gap between the trim 5 and the trim 5 is considerably narrower at the roof side edge 1b than at the lower end of the front pillar 1a. Therefore, the lip 34 is excessively pressed against the trim 5 at the roof side edge 1b, and if the gap between the weather strip 3D and the trim 5 is set wide to avoid this, the lip 34 comes into contact with the trim 5. Becomes insufficient in the lower part of the front pillar 1a, and in either case, the appearance inside the vehicle may be deteriorated.

Therefore, the present invention provides a roof side sealing structure in which the weather strip is stably attached to the roof side and the contact state of the lip with the vehicle interior member is uniform over the entire weather strip when the door glass is closed. Is a challenge.

[0007]

[Means for Solving the Problems]

 As shown in FIG. 1, the present invention embeds an insert plate 4 having an inverted L-shaped cross section in a base portion 31 having an inverted L-shaped cross section of a weather strip 3A attached along a roof side 1 and a weather strip. 3A is directly fixed to the roof side 1 by a fixture 6 penetrating the base 31 thereof.

[0008]

[Action]

 In the present invention, since the weather strip 3A is directly fixed to the roof side 1, the mounting state is stable and a good door glass sealing property is maintained even after many years of use. Further, since the insert plate 4 is fixed to the roof side 1 integrally with the weather strip 3A and imparts rigidity to the base 31, the weather strip 3A and the trim which is an in-vehicle member are pressed even if the door glass 2A is pressed. The width of the gap with the trim 5 does not change, and the contact state of the lip 34 with the trim 5 is uniform over the entire circumference of the weather strip.

[0009]

【Example】

 FIG. 1 shows a first embodiment of the present invention. The roof side 1 having the flange 11 has an inverted L-shaped cross section, and the flange 11 is fitted with a trim 5 having a U-shaped cross section.

The weather strip 3A includes a base portion 31 having an inverted L-shaped cross section, a hollow seal portion 32 formed at a front end of the base portion 31 on the vehicle outer side, and an inner portion extending from the tip of the base portion 31 on the vehicle inner side in the vehicle outer direction. A seal lip 33 and a lip 34, which extends from the inner end of the base portion 31 toward the inside of the vehicle toward the inside of the vehicle and the tip end of which abuts against the trim 5, are provided. The weather strip 3A is an extruded product, and the base 31 and the hollow sealing portion 32 except for the seal wall 321 are made of solid rubber, and the other portions are made of sponge rubber. An insert plate 4 having an inverted L-shaped cross section is embedded in the base 31 over substantially the entire width thereof.

When the door glass is closed, the seal wall 321 of the seal portion 32 is pressed against the outer circumference of the door glass 2A so that the inner seal lip 33 is pressed against the inner surface of the door glass 2A.

The weather strip 3A is fixed to the roof side 1 with a grommet screen 8A in which the base ends of the molding plates 9 are overlapped with each other. That is, by inserting the grommet 81 on the roof side 1, inserting the screw 82 from the inside of the base 31 into the hole previously provided in the base 31 including the insert plate 4, and screwing it into the grommet 81, the weather strip 3A is formed. Fixed.

In the above seal structure, however, the weather strip 3A is fixed to the roof side 1 by the grommet screw 8A, so that the weather strip 3A is not displaced even during long-term use, and the mounting state is stable. Further, the weather strip 3A is pushed into the inside of the vehicle through the inner seal lip 33 at the upper portion facing the door glass 2A, particularly the roof side edge 1b (FIG. 4). It is received by the base 31. Therefore, the gap between the weather strip 3A and the trim 4 is uniformly maintained over the entire length of the weather strip 3A, the contact state of the lip 34 with the trim 5 is also uniform, and the appearance on the indoor side around the roof side is good.

FIG. 2 shows a second embodiment of the present invention. In the weather strip 3B, both ends of a base portion 31 having an inverted L-shaped cross section are connected by seal walls 321 to form a hollow seal portion 32, and the seal wall 321 is pushed up by the outer periphery of the door glass. The weather strip 3B is fixed to the roof side 1 by a grommet 8B with a pin.

That is, an oval hole is formed in the base portion 31 in which the insert plate 4 is embedded, the base end portion of the molding plate 9 stacked on the base portion 31 and the roof side 1, and the head portion is formed in this hole. 831 has an oval shape, and the clip 83 in which the pin 84 has been previously inserted is inserted from the outside of the roof side 1, and the clip 83 is rotated to engage the head portion 831 with the base portion 31 of the weather strip 3 B to seal the seal. The weather strip 3B is fixed to the roof side 1 by pushing the pin 84 from the outside through the wall 321.

The other structure is the same as that of the first embodiment, and substantially the same operation and effect are obtained.

FIG. 3 shows a third embodiment of the present invention. In this embodiment, the insert plate 4 and the molding plate 9 are formed as a single plate, and the insert plate 4 on the base end side having an inverted L-shaped cross section is embedded in the base portion 31 of the weather strip 3C.

The other structure is substantially the same as that of the first embodiment, and has the same operation and effect.

[0019]

[Effect of the device]

 As described above, in the seal structure of the present invention, the weather strip is stably fixed to the roof side for a long period of time. Even if the pressing force of the door glass against the weather strip is partially different, the gap between the weather strip and the in-vehicle member along the gap is maintained uniformly over the entire length of the weather strip, and seals the gap. Therefore, the contact state of the lip provided on the weather strip with the trim is uniform over the entire length of the weather strip, and the interior side along the roof side looks good.
