Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle body side weather strip.

[0002]

2. Description of the Related Art As is well known, in a sashless type vehicle, a metal retainer is previously screwed to the mounting surface of the opening edge of the vehicle body, and a hollow seal is continuously extruded on the retainer. The base part of the body side weather strip having a lip is fitted and attached. However, this requires two parts, a retainer and a body side weather strip, and man-hours for managing parts and assembling in an automobile assembly line. It takes a lot of man-hours, which is disadvantageous in terms of cost.

Therefore, as a countermeasure against this, body side weather strips as shown in FIGS. 3 and 4 have already been proposed. As shown in the figure, this is a base portion 5 in which a metallic core material 6 is embedded to form a pair of side walls 7 and 8 and a bottom wall 9 in a substantially U-shaped cross section, and a passenger compartment I of the base portion 5. A hollow seal lip 10 formed integrally with the end of the side wall 8 on the side of the vehicle, and a free end portion of the seal lip 10 and an end of the side wall 7 on the outside O side of the vehicle that engage with each other. Part 11, 12
Is formed by molding.

This body side weather strip is
First, the bottom wall 9 of the base portion 5 is fixed to the mounting surface 4 formed on the vehicle body opening edge portion 3 to which the door 2 of the vehicle body 1 is attached with the screws 13 at a plurality of places, and the engaging portion 11 of the seal lip 10 is fixed. It is assembled by elastically engaging with the engaging portion 12 of the side wall 7 of the base portion 5. This similar structure is, for example,
No. 148825 and Japanese Utility Model Laid-Open No. 3-69525.

[0005]

As shown by the broken line in FIG. 4, the base portion 5 can be attached to the attachment surface 4 by a tool 14 such as a screwdriver in the original state of the body side weather strip with the seal lip 10 released. After that, by using a jig such as a spatula or a roller, the engaging portion 11 of the seal lip 10 is pushed into the engaging portion 12 on the base portion 4 side so that the engaging portions 11 and 12 are engaged with each other. It can be connected and the retainer, which was previously indispensable for assembling the body side weather strip, can be eliminated.

However, in this structure, the seal lip 10
If the free end portion of the seal lip 10 is connected to the base portion 5 in advance, the base portion 5 cannot be attached to the attachment surface 4. Therefore, the connecting operation of the free end portion of the seal lip 10 is performed by an automobile. However, a jig is required for this connecting work, and a considerable amount of time and skill are required for the assembling work.

Therefore, the present invention provides a body side weather strip for an automobile, which not only does not require a retainer but which can be assembled quickly and easily.

[0008]

A pair of side walls and a bottom wall are formed into a substantially U-shaped cross section, and the bottom wall is fastened to a mounting surface of an opening edge of a vehicle body. And a hollow seal lip connected to the terminal, and
In a body side weather strip in which a free end portion of the seal lip and the other side wall are formed with engaging portions that engage with each other, one of the side walls corresponds to a fastening position of the bottom wall. A window portion for working is formed in an appropriate range from the end of the side wall.

[0009]

When the free end portion of the seal lip is fixed to the vehicle body opening edge portion while the engaging portions are previously engaged with each other and connected to the base portion, the edge portion of the seal lip facing the window portion is fixed. Since the window portion is expanded by bending with a fingertip or the tip portion of the tool, the bottom wall of the base portion can be fastened to the mounting surface of the vehicle body opening edge portion by the tool through the window portion.

[0010]

An embodiment of the present invention will be described in detail below with reference to the drawings.

In FIGS. 1 and 2, 20 is a pair of side walls 2.
1, 22 and the bottom wall 23 are metal base portions formed in a substantially U-shaped cross section. A plurality of mounting holes 24 are formed in the bottom wall 23, and the bottom wall 23 is opened through the mounting holes 24. Edge 3
The mounting surface 4 is fastened and fixed with a screw 13.

A hollow seal lip 25 is continuously provided on a side wall 21 of the base portion 20 on the outside O side. The seal lip 25 is integrally formed by extrusion molding with the base portion 20, or by fitting and adhering to the end of the side wall 21.

Engagement portions 26 and 27 are formed on the free end of the seal lip 25 and the end of the side wall 22 of the base portion 20 on the vehicle compartment I side. Part 2
The seal lip 25 is connected to the base portion 20 by the mutual engagement of 6, 27.

Here, on the side wall 22 of the base portion 20 on the passenger compartment I side, a window portion for working is provided at a portion corresponding to the position where the mounting hole 24 of the bottom wall 23 is opened from the terminal to an appropriate range. 28 is formed. In this embodiment, the notch 29 is also formed on the seal lip 25 side so that the opening area of the window 28 is enlarged to the seal lip 25 side.

According to the structure of the above embodiment, the free end portion of the seal lip 25 and the engaging portion 26 thereof are previously attached to the base portion 20.
When the bottom wall 23 of the base portion 20 is fixed to the mounting surface 4 of the vehicle body opening edge portion 3 in a state in which the bottom wall 23 of the base portion 20 is engaged with and coupled to the engaging portion 27 formed on the side wall 22 of the vehicle compartment I side, as shown in FIG. As shown, by bending the edge of the seal lip 25 facing the window 28 toward the center of the seal lip 25 with a fingertip or a tool such as a screwdriver, the opening area of the window 28 is reduced.
5, the mounting hole 24 of the bottom wall 23 can be easily seen from the outside, so that the screw 13 and the tool 14 are inserted through the window 28, the screw 13 is passed through the mounting hole 24, and the mounting surface 4 is attached. The bottom wall 23 can be easily screwed and fastened to the mounting surface 4
Can be fixed to. After the bottom wall 23 is fixed, if the external force at the edge of the seal lip 25 is released, it is restored by the elasticity of itself and the window 28 only opens in the original surface of the side wall 22 and is visible from the outside. Does not hurt.

In the above embodiment, the seal lip 25 is connected to the side wall 21 of the base portion 20 on the outside O side.
You may make it connect with the side wall 22 terminal of the vehicle compartment I side,
The window 28 is not limited to the side wall 22 on the vehicle interior I side, and may be provided on the side wall 21 on the outside O side. However, in the case where the window portion 28 is provided on the side wall 21 on the O side outside the vehicle, in a normal state, if a decorative lip that shields the window portion 28 from the outside is integrally formed with the seal lip 25, the appearance may be impaired. Absent.

Further, in the above embodiment, the base 20 is made of metal, but it is of course possible to use an integrally molded type of rubber, resin or the like in which a metal core is embedded as in the conventional case. is there.

[0018]

As described above, according to the present invention, the base portion can be fastened and fixed to the mounting surface of the opening edge of the vehicle body with a screw or the like through the window portion of the base portion. The end portions can be engaged with each other to connect to the side wall of the base portion, and the seal lip can be sub-assembled. Therefore, the work of assembling the body side weather strip to the vehicle body opening edge portion can be performed. In addition to being able to perform quickly, it is not necessary to attach the seal lip free end portion using a jig after attaching it to the opening edge of the vehicle body, so that the operation can be performed easily. It can greatly contribute to cost reduction.
