Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a grass run mounted on a vehicle door.

[0002]

[Prior art]

 FIG. 4 is an overall view of a vehicle door embodying the present invention, and FIG. 5 is an enlarged view of part A of FIG. A vehicle door, generally designated by reference numeral 10, is composed of an outer panel 12 and an inner panel 14 and has an opening 50 for mounting a windshield. The front edge portion of the panel of the door 10 has an inclined panel 20 along a pillar of the vehicle body and an upright panel 22 supported by the vehicle body via a hinge. The corner portion 24 between the inclined panel 20 and the upright panel 22 needs to be provided with a notch for convenience of molding the panel. The window glass mounted in the opening 50 of the door 10 is slidably supported by the panel via a glass run. A window glass sealing structure is disclosed, for example, in Japanese Patent Laid-Open No. 58-214411.

[0003]

[Problems to be solved by the device]

 The glass run attached to the door panel slidably supports the window glass and also prevents raindrops from entering the vehicle interior. However, there is a case where water enters the inside of the grass run through the interface between the grass run and the panel. A channel is provided on the inner surface of the grass run to guide this water downward to the vehicle body. However, there is a risk that water will flow to the passenger compartment side at the corners of the panel, and measures must be taken. The present invention provides a seal structure that reliably guides water from a corner portion to a guide rail provided in an upright portion.

[0004]

The glass run of the present invention has a first lip and a second lip provided in parallel to a joint surface with respect to a door panel, and a lower end of the first lip disposed inside the vehicle. An extension portion is provided in the portion that approaches toward the second lip arranged on the outside of the vehicle.

[0005]

[Action]

 The water droplets penetrating between the panel and the glass run flow downwards through the channel formed between the first lip and the second lip, but are guided by the extension provided in the first lip, It is reliably fed into the guide rail.

[0006]

【Example】

FIG. 2 shows a state in which the window glass 60 is supported by the front edge panel 22 of the door via the glass run 70, and FIG. 3 shows the shape of the corner portion of the glass run 70. The grass run 70 is made of a flexible material, and is attached to the panel side by inserting the leg portion 75 provided on the back side of the main body portion 71 into the mating portion 22A of the front edge panel 22. The entire door 10 is opened and closed with respect to a vehicle body panel 40 having a seal 42. A parallel first lip 72 and a second lip 74 are provided on the joint surface of the glass run 70 with the panel 22, and a channel 73 for guiding raindrops or the like is formed between the both lips 72, 74. The water droplets that have hit the outside of the panel 22 enter the inside through the gap between the second lip 74 and the panel 22 shown by the arrow W ₁ . The water droplets that have entered penetrate the channel 73 formed between the first lip 72 and the second lip 74 and flow down in the direction of the arrow W ₂ .

The glass run 70 is bent so as to cover the corner portion 24 along the upright portion from the inclined portion of the front edge portion of the door panel. Conventionally, the tip end portion 72A of the corner portion of the first lip 72 disposed on the passenger compartment side has been processed into a shape for guiding water droplets to the guide rail 80 of the window glass provided in the upright portion. Since the window of the vehicle door has a shape in which the upper side is inclined toward the passenger compartment, water droplets flowing down the channel 72 along the arrow W ₂ always try to flow into the passenger compartment. The front end portion 72A of the first lip 72 contacts the panel side and is positioned. Nevertheless, because of the out portion cut the panel in the corner 24, the distal end portion 72 A off the panel, water droplets penetrated into the vehicle side along the arrow W _3, does not properly fall into the guide rail 8 0 Things happen.

FIG. 1 is an explanatory view showing the structure of the grass run of the present invention. The grass run 170 disposed at the front edge of the door panel is mounted by inserting the leg portion 175 of the main body portion 171 into the mating portion of the door panel. A first lip 172 and a second lip 174 are formed on the joint surface of the door panel. The first lip 172 is on the inside of the vehicle and contacts the mating portion of the door panel, and the second lip 174 is pressed against the outside of the door panel. A channel 173 for guiding a water drop is formed between the first lip 172 and the second lip 174.

The glass run 170 covers the corner portion 24 and is connected to a guide rail 80 formed below the corner portion 24 to form an upright panel. The lower end portion 174A of the second lip 174 is positioned by being joined to the upper surface of the guide rail 80. The lower end portion 172A of the first lip 172 is formed as an extension portion that is bent toward the vehicle exterior side where the lower end portion 174A of the second lip 174 is located. The bent extension 172A guides the water droplets flowing down in the channel 173 along the arrow W ₂ to the outside of the vehicle as indicated by the arrow W ₄ . The water droplets flowing in the direction of the arrow W ₄ reliably fall into the guide rail 80 without entering the inside of the vehicle.

[0010]

[Effect of device]

 As described above, the glass run of the present invention is mounted on the panel around the window opening portion of the door panel and has the function of guiding the window glass and the function of sealing, and is provided in parallel with the joint surface on the panel side. And a second lip, and an extension portion is provided at a lower end portion of the first lip disposed inside the vehicle toward the second lip disposed outside the vehicle. .

By providing this extension portion, water droplets that have entered between the glass run and the panel can be reliably guided to the guide rail provided on the upright portion of the door panel, and will not enter the inside of the vehicle. Moreover, the cutout portion of the panel is surely covered by this extension portion, and the sound insulation performance is improved. Further, it is easy to position the lower end of the grass run with respect to the upper end of the guide rail. In addition, in the above-described embodiment, the seal structure of the front edge portion of the door panel has been described, but the present invention can be applied to the seal structure of the rear edge portion of the door panel.
