Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a door weather strip that seals between an opening edge of a vehicle body and a sash.

[0002]

[Prior art]

 Description will be made with reference to FIGS. 1 to 3. P is the outside of the vehicle and Q is the inside of the vehicle. Conventionally, as a door weatherstrip that seals between the body opening edge portion 10 of the automobile and the sash 20, as shown in FIGS. 3 and 4, from the inside Q to the base portion 31 fitted to the retainer 21 of the sash 20. In this order, a hollow seal portion 32, a lip 33 that elastically contacts the body opening edge portion 10 and a decorative lip 34 that fills the gap between the body opening edge portion 10 and the sash 20 are integrally combined, but are used. The one that elastically contacts the roof portion 11 and the one that elastically contacts the rear pillar portion 12 have different sectional shapes from the door entry loci E 1 and F 2 as shown in FIGS. 3 and 4.

Therefore, the above-mentioned conventional weather strip needs to use a die for rubber extrusion having a different shape, which lowers the yield, increases the manufacturing cost, and, in the assembled state, the front and rear seams are different. There is a problem that it is visible from the outside and impairs the appearance of the vehicle.

[0004]

[Problems to be solved by the device]

 The problem to be solved is that, in the conventional weather strip, the one that elastically contacts the roof portion 11 and the one that elastically contacts the rear pillar portion 12 have different cross-sectional shapes from the door entry loci E and F, respectively. Therefore, it is necessary to use differently shaped rubber extrusion die, which lowers the yield, increases the manufacturing cost, and in the assembled state, the front and rear seams can be seen from the outside, and the appearance of the vehicle is impaired. That is.

[0005]

[Means for Solving the Problems]

 This will be described with reference to FIGS. 1 and 4 to 6. The present invention elastically contacts the body opening edge portion 10 in order from the vehicle inner side Q to the base portion 31 fitted to the retainer 21 of the sash 20 for sealing between the vehicle body opening edge portion 10 and the sash 20. A door weather strip formed by integrally connecting a hollow seal portion 32, a body opening edge portion 10 and a decorative lip 34 that fills a gap between the sash 20 and a hollow lip portion 32 on the lower surface of the sash 20 side. The projection 35 of the roof portion 11 and the rear pillar portion 12 is continuously formed while the downward projection 35 is provided, and the projection of the roof portion 11 is formed longer than the projection of the rear pillar portion 12.

[0006]

【Example】

 An embodiment will be described. 10 is an opening edge of an automobile body, 20 is a sash, 21 is a retainer, 30 is a door weather strip fitted in the retainer 21, and is a weather strip common to a roof of a rear door and a rear pillar. A base portion 31 fitted to the retainer 21, a hollow seal portion 32 integrally joined to the base portion 31 in order from the vehicle interior side Q, a lip 33 and a decorative lip 34, and on the lower surface of the hollow seal portion 32. A downward projection 35 is provided on the sash 20 side. The hollow seal portion 32 and the lip 33 are in elastic contact with the body opening edge portion 10 respectively, and the decorative lip 34 fills the gap between the body opening edge portion 10 and the sash 20. At the time of mounting, the projection 35 is used as it is on the rear roof portion, but the rear pillar portion is used as shown in FIG. 6 by cutting the portion Z shown in FIG. 4 in a burr state and shortening it. That is, the protrusions 35 of the roof portion 11 and the rear pillar portion 12 are continuously formed, and the protrusion of the rear pillar portion 12 is formed shorter than the protrusion of the roof portion 11.

The operation will be described. As described above, the hollow seal portion 32 and the lip 33 are elastically contacted with the body opening edge portion 10 while leaving the projection 35 in the rear door roof portion as it is, and the projection 35 is illustrated in the rear pillar portion 12. The portion Z shown in 4 is cut in a burr state and shortened so as to be low as a whole as shown in FIG. 7 so that the door weather strip 30 does not interfere with the body opening edge portion 10 when the door is opened and closed, and the rear roof and rear pillar are passed through. Therefore, one seamless weather strip can be used.

[0008]

[Effect of device]

 Since the present invention is configured as described above, one seamless weather strip can be used, only one die is required for extrusion, no intermediate joining is required, and cost is reduced. Molding is also unnecessary, and the color matching between the molded part and the extruded part is also unnecessary, improving the appearance.
