Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a glass run channel for a roof portion that seals between a lower surface of a window frame of a vehicle entrance and exit and a door glass.

[0002]

[Prior Art]

 Conventionally, as a cross-sectional shape of a roof portion of a glass run channel that seals between a lower surface of a window frame and a door glass, as shown in FIGS. 2 to 4, as shown in FIGS. The hollow seal part 4b and the door glass 3 where the upper end of the door glass 3 elastically contacts the upper part P of the outside of the vehicle P and the lower end Q of the inside of the car, respectively, of the glass run channel base 4a fitted in the retainer 2a formed between the lower end and the lower end. There is a glass run channel 14 in which a lower seal lip 4c that elastically contacts the inner surface is integrally connected. The hollow seal portion 4b is provided with a vehicle exterior vertical plane V that is flush with the outer surface of the window frame 2 and a horizontal elastic contact surface H with the door glass 3 that extends horizontally outward from the middle of the base portion 4a. The outer vertical surface V extends downward slightly beyond the horizontal elastic contact surface H and forms an extension portion E.

However, when the position of the extension portion E is in the position X which is biased toward the vehicle exterior side P from the proper position M, the extension is performed with the door glass 3 closed as shown in FIG. When the portion E does not come into contact with the outer surface of the upper portion of the door glass 3 and the sealing performance of this portion is impaired, or conversely, the position of the extended portion E is at the position Y that is biased toward the vehicle inside Q from the proper position. As shown in FIG. 4, there is a problem in that the extension portion E is caught in the upper end of the door glass 3 and the sealing performance is impaired.

Further, as shown in FIG. 5, there is also a case where an upward inward arcuate projection piece Ta is provided on the surface of the base portion 4a on the side of the window frame 2, but the shape of this arcuate projection piece Ta is the door glass 3 The position of the extension portion E changes as it flexes freely with respect to the rising and raising force of. In addition, there is a problem that the arc-shaped projecting piece Ta must be crushed or the die must be divided by the arc-shaped projecting piece Ta to mold the product in which molding is performed.

[0005]

[Problems to be solved by the device]

 The problem to be solved is that when the extension portion E of the outer vertical surface V of the hollow seal portion 4a is biased toward the inside or outside of the proper position M due to variations in manufacturing or variations in the door glass 3. In the closed state of the door glass 3, the extended portion E does not come into contact with the outer surface of the upper portion of the door glass 3, which may impair the sealing performance.

[0006]

[Means for Solving the Problems]

 This will be described with reference to FIG. The roof glass run channel 4 according to the present invention is a vehicle run side P of a grass run channel base 4a fitted in a retainer 2a formed between an outer side P end of a lower surface of a window frame 2 and a lower end of a vehicle inner side Q. A hollow seal portion 4b, to which the upper end of the door glass 3 elastically contacts, is integrally connected to the upper portion, and the vehicle exterior vertical plane V of the hollow seal portion 4b is slightly downward beyond a horizontal elastic contact surface H with the door glass 3. It is a glass run channel 4 that seals between the lower surface of the window frame 2 where the extended portion E is formed and the door glass 3, and the position of the extended portion E is located on the window frame 2 side surface of the base portion 4a. A position adjusting projection T for adjustment is provided.

[0007]

【Example】

 An embodiment will be described with reference to FIGS. 1 and 6. 1 is a door of an automobile, 2 is its window frame, and 2a is a retainer into which a glass run channel is fitted. It is formed between the lower end of the inner Q plane and the vertical plane. 3 is a door glass, 4 is a glass run channel that seals between the lower surface of the window frame 2 and the door glass 3, and the bottom part 4a fitted into the retainer 2a is above the outer side P of the vehicle, and the upper end of the door glass 3 is provided with a bullet. The hollow seal portions 4b that are in contact with each other are integrally connected, and the vertical outer surface V of the hollow seal portion 4b is extended slightly below the horizontal elastic contact surface H with the door glass 3 to form an extended portion E. In addition, a projection T for adjusting the position for adjusting the position of the extended portion E is provided on the surface of the base 4a on the side of the window frame 2.

[0008] Explaining the operation, when the base 4a is fitted into the retainer 2a and the glass run channel 4 is attached to the window frame 2, the horizontal elastic contact surface H of the hollow seal portion 4b is closed when the door glass 3 is closed. The extended portion E is elastically contacted with the upper outer surface of the door glass 3, and the lower seal lip 4c is elastically contacted with the inner surface of the door glass 3, respectively, to seal the inner and outer sides of the vehicle glass 3, respectively. At this time, even if the glass run channel 4 and the door glass 3 have some geometrical variations, especially the position of the extension portion E, the position adjusting protrusion T provided on the base portion 4a causes the extension portion E to be located at an appropriate position. Since the position is adjusted so as to come, the extension portion E does not separate from the door glass 3 unlike the conventional one, and the biting by the door crow 3 does not occur. Incidentally, when the glass run channel 4 is manufactured, the projection T is utilized to match with the window frame 2.

[0009]

[Effect of the device]

 Since the present invention is configured as described above, the extension E of the vertical portion V of the outer side of the hollow seal portion 4b, which is seen only in the prior art, does not contact the upper outer surface of the door glass 3, or the opposite. The problem that the sealability is impaired by the extension E being caught in the upper end of the door glass 3 is completely eliminated.

Further, compared with the conventional arc-shaped projection piece Ta shown in FIG. 5, the projection T facilitates mass production of vehicles and changes in the position of the extension portion E due to changes in the retainer 2a and the door glass 3 are easier. The part corresponding to the protrusion T of the die of the extruder can be adjusted and the extension part E can be brought to a proper position. Further, when the retainer 2a is unevenly formed by the stretch bender processing of the window frame 2 in the related art, the padding may be partially attached to the base portion 4a. The height of the protrusion T can be varied, and the height of the protrusion T can be changed within one product.
