Description

[0001]
[Industrial application fields]
The present invention relates to a weather strip that is clamped to a vehicle body flange with a welt.
[0002]
[Prior art]
FIG. 2 shows a case where a weather strip 7 is attached to a vehicle body flange F of a back door of an automobile. The vehicle body flange F is inserted into a welt 7a and fixed to the outer wall on the outside of the vehicle with a double-sided tape 8 interposed. FIG. 3 shows a case where the weather strip 9 is attached to the vehicle body flange F of the side door. The vehicle body flange F is inserted into the welt 9a and fixed to the outer wall with a double-sided tape 8 interposed therebetween.
[0003]
In the case of the both weather strips 7, 9, these welts 7a, 9a are both formed with square-shaped bent portions 10, 11 on the inner wall on the indoor side.
The attachment to the vehicle body flange F is performed by inserting the vehicle body flange F into each of the welts 7a and 9a. At this time, the guide surfaces G of the bent portions 10 and 11 are guided to facilitate the insertion of the vehicle body flange F. To. Further, the bent portions 10 and 11 at the time of attachment of the welts 7a and 9a have a role of temporarily fixing to the vehicle body flange F. Reference numeral 12 denotes a trunk panel, a back door, or a 13 door panel.
[0004]
[Problems to be solved by the invention]
However, since the guide surface G of the bent portions 10 and 11 does not have a sufficiently wide guide width, when the body flange F is thick, the ends of the bent portions 10 and 11 are easily caught, and the welts 7a and 9a There is a problem that the insertion becomes difficult, and in particular, the vehicle body flange F tends to be thicker and more difficult to install in recent years due to the rigidity of the vehicle body.
Accordingly, an object of the present invention is to provide a weather strip that is improved in mountability by a welt having a guide portion that can reliably guide even when a vehicle body flange is thick.
[0005]
[Means to solve the problem]
In order to achieve such an object, the structure of the present invention is a weather strip in which a welt 2 having a U-shaped cross section is bonded to a vehicle body flange F by attaching a double-sided tape 4 to an outer wall 2a on the outdoor side, as shown in FIG. 1, the end of the inner wall 2 b on the indoor side of the welt 2 includes a lip portion 5 a extending inward and an introduction portion 5 b extending inclined toward the outdoor side, and the thickness of the inner wall 2 b on the indoor side of the welt 2. A plate-like guide portion 5 that is wider than the end of the inner wall 2b and protrudes from the end of the inner wall 2b toward the outdoor side and the indoor side, and when the welt 2 is attached by inserting the vehicle body flange F, the guide portion is attached to the vehicle body flange F. In this state, the vehicle body flange F is guided and smoothly slid into the welt 2 with 5 being always applied.
[0006]
【Example】
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In FIG. 1, reference numeral 1 denotes a weather strip, which includes a welt 2 having a U-shaped cross section of a solid rubber material sandwiched between body flanges F, and a hollow seal portion 3 of a sponge material that elastically contacts a trunk panel or back door when closed. Become.
[0006]
The welt 2 has a plate-like shape composed of a double-sided tape 4 attached to the outer wall 2a on the outdoor side, and a lip portion 5a extending inward and an introduction portion 5b extending obliquely toward the outdoor side at the end of the inner wall 2b on the indoor side. A guide portion 5 is provided.
When the welt 2 is attached by inserting the vehicle body flange F, the guide portion 5 having a sufficiently wide width always hits the vehicle body flange F, and the vehicle body flange F can be guided and smoothly slid into the welt 2. That is, since the guide portion 5 is wide, it does not become difficult to be inserted due to being caught even when the vehicle body flange F is thick like the guide surface G of the conventional square-shaped portion.
[0007]
【The invention's effect】
The weather strip of the present invention is provided with a wide guide portion at the end of the inner wall of the car interior of the welt with double-sided tape affixed to the outer wall of the outer side of the vehicle. There is a feature that, even when the vehicle body flange is thick, it is always guided by the wide guide portion and the mounting workability can be improved.

Claims (1)

In a weather strip in which a double-sided tape is attached to the outer wall of the outdoor side of the welt with a U-shaped cross section, and is sandwiched between the flanges of the vehicle body. A plate-shaped guide portion is provided which includes an introduction portion extending in an inclined manner and is wider than the thickness of the inner wall on the indoor side of the welt and protrudes from the end of the inner wall toward the outdoor side and the indoor side. A weather strip, wherein when inserted and attached, the vehicle body flange is guided and smoothly slid into the welt while the guide portion is always in contact with the vehicle body flange.
