Problems solved by technology

[0005] However, when the opening width is changed locally, the manufacturing process is correspondingly complicated and the manufacturing equipment is correspondingly complicated
With this structure, there is a disadvantage in that the manufacturing cost of the weather strip increases
In addition, there have been examples showing that only reducing the opening width is not enough as a measure to counteract the opening deformation of the blank holder
In addition, when the clamping action is taken subsequently, due to the addition of a process, there is also the disadvantage of increasing the manufacturing cost.

Embodiment Construction

[0033] Hereinafter, the embodiments are described by referring to the drawings. Such as figure 2 , image 3 As shown, according to the present embodiment, the weather strip 1 is mounted on the body side along the peripheral flange of the door opening 4 corresponding to the side door 3 on the vehicle 2 . In addition, the weather strip 1 is made into a long strip with a fixed cross section by extrusion molding.

[0034] Description based on Figure 1A. The structure of the weather strip 1 of 1B, the weather strip 1 has a crimping portion 6 mounted on the flange. The flange part 6 includes a bottom wall part 9, an inner wall part 10 and an outer wall part 11, the two side wall parts constitute a pair of side wall parts, and the cross section of the flange part is substantially U-shaped as a whole. A retaining lip 12 extending into the crimp portion 6 is formed on the inner side wall portion 10 , while a plurality of auxiliary lips 13 are formed on the inner side of the outer...

Abstract

A sealing strip includes a beading portion adjusted to fit onto a flange, a sealing member having a hollow portion, and a cover lip. The hemming portion includes: a bottom wall portion; an inner side wall portion and an outer side wall portion which constitute a pair of side wall portions and are formed to have a substantially U-shaped cross section as a whole; within the blank holder portion of the construction. In the bone piece of the core, an angle θa is formed by the bottom wall member pre-embedded in the bottom wall portion and the inner member pre-embedded in the inner side wall portion, and the angle θa is formed by the bottom wall member and the outer member pre-embedded in the outer side wall portion θb, both the angle θa and the angle θb are made acute.

Description

technical field [0001] The invention relates to a weatherstrip having a trim part having a substantially U-shaped cross-section. Background technique [0002] Usually, for example, a weather strip made of a rubber material such as EPDM is placed on a door opening periphery of a vehicle body such as an automobile. Through extrusion molding, the sealing strip is made into a long strip with a fixed cross-sectional shape. In addition, if Figure 6A As shown, the weather strip 51 includes a crimp portion 52 retained by a press fit on the flange along the periphery of the door opening, and a hollow seal member 53 which is arranged to protrude from the crimp portion 52 . The crimp portion 52 includes a base portion 54 , an inner wall portion 55 and an outer wall portion 56 , and the two side wall portions extend substantially parallel to the base portion 54 to form a substantially U-shaped cross-section as a whole. A metal core 57 is pre-embedded in the bead portion 52 to keep th...
