[Industrial applications]

 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a weather strip for an automobile, and more particularly to a weather strip attached to an inner side of a door glass along a belt line of an automobile door.

[0002]

[Prior art]

 As shown in FIG. 2, a weather strip 3 is attached to the automobile door 1 along a belt line 10 thereof. This weather strip 3 is composed of an outer side weather strip along the belt line of the door outer plate and an inner side weather strip along the belt line of the interior trim of the door inner plate. As represented by the weather strip 3 on the inner side of 3, a basic structure including a mounting base 31 in which a core member 34 is embedded and seal lips 32 and 33 extending from the mounting base 31 is provided. The inner and outer surfaces of the door glass 2 are wiped by the seal lips 32 and 33 when the door glass 2 is moved up and down. In the figure, 5 is an interior trim of the door inner plate.

By the way, as shown in FIG. 2, there is a hard top vehicle in which the rear end portion 11 of the belt line 10 of the rear door 2 is curved upward. There is also a type in which the front end of the belt line 10 is also curved upward. In such a case, the weather strips 3 on the outer side and the inner side also have to be curved along the curved portion of the belt line 10.

Conventionally, a roll bender device has been used as a bending means. However, the roll bender device is large in size, and the processing becomes expensive. Therefore, for the inner side weatherstrip, which has almost no role of preventing water from entering from the outside of the vehicle into the door, a large number of slits are provided in the longitudinal direction from the lower edge side at a predetermined interval at the rear end of the strip. Means for expanding these slits to bend the weather strip is used. However, if a large number of slits are provided in this manner, at least the lower seal lip 33 is divided, and the divided seal lip 33 is twisted or irregularly inverted when the door glass 2 is moved up and down. Inconvenience occurs.

[0005]

[Problems to be solved by the device]

 Therefore, the present invention has an object to provide a weather strip that can be easily bent along a door belt line without using a roll bender device or dividing the seal lip into a large number. Is.

[0006]

[Means for Solving the Problems]

 The present invention, as shown in FIG. 1 (A), is used on the inner side of a belt line of a door, and is located at the end of a weather strip 3 in which a core member 34 is embedded, from the lower edge to the upper side. To form a T-shaped slit 4 consisting of a vertical slit 4a extending in the vertical direction and a horizontal slit 4b extending along the upper edge thereof, and expanding the vertical slit 4a as shown in FIG. 1 (B). However, the end of the weather strip 3 is formed in a curved shape along the end of the door belt line.

[0007]

[Action]

 When the slit 4a in the vertical direction is expanded, the slit 4b in the horizontal direction is bent into a curved shape, and accordingly, the entire end portion of the weather strip 3 is curved.

[0008]

【Example】

 As shown in FIG. 1 (A), the weather strip 3 attached to the inner side of the door glass of the door belt line has two upper and lower stages extending from the attachment base 31 and the surface of the attachment base 31 facing the door glass. Sealing lips 32, 33 are provided, and a sheet metal core 34 is embedded in the mounting base 31. This weather strip 3 is extruded.

At the rear end of the weather strip 3, a T-shaped slit 4 consisting of a vertical slit 4a extending upward from the lower edge and a lateral slit 4b along the upper edge is formed by punching. is there. The longitudinal slit 4a separates the mounting base 31 as well as the sealing lips 32, 33.

As shown in FIG. 1 (B), the rear end portion of the weather strip 3 having the T-shaped slit 4 is expanded by expanding the lower end side of the vertical slit 4a. Bends upward, and the rear end of the weather strip 3 bends accordingly. The curvature is determined by the height position and length of the slit 4b in the horizontal direction, the degree of opening of the slit 4a in the vertical direction, and the like. By adjusting these, the rear end portion of the weather strip 3 is formed into a curvature that follows the curvature of the rear end portion of the belt line of the interior trim 5 to which the weather strip 3 is attached.

For example, when bending gently over a long range, the lateral slit 4b is formed long. Further, when bending with a large curvature centering on the slit position, the bending work can be facilitated by raising the position of the slit 4b in the lateral direction. Usually, the width of the slits 4a and 4b is about 2 to 5 mm, and the length of the slit 4b in the lateral direction is set in the range of 10 to 100 mm depending on the curvature to be obtained.

[0012]

[Effect of device]

 As described above, the present invention forms a T-shaped slit in the weather strip that is attached to the inner side of the door glass of the belt line of the automobile door, thereby working the weather strip into a curved shape that matches the curved shape of the belt line. It can be bent easily. Further, the seal lip of the weather strip is separated at the slit forming portion, but since it is separated only at one position, the function of the seal lip is not hindered.
