Weather strip

Abstract

A weather strip is provided in which the trim portion does not have an insert member embedded, a notch or a thin wall portions are formed in a portion near the bottom wall of the vehicle exterior sidewall and the vehicle interior sidewall, a thick wall portion is formed in the further front end than the thin wall portion, and both the front ends are inclined so as to approach each other. Two of each of flange holding lips are formed on each of the inner surfaces of both sidewalls; and the angle at which the flange holding lips of the opening side are projected is formed larger than the angle of the flange holding lips of the bottom wall side; the front ends of the flange holding lips of the opening side are formed so as to be contact with or close to each other; the front ends of the flange holding lips 25 and 27 of the bottom wall side are linearly formed to have a gap in the width direction or in a direction orthogonal to the width direction.

Description

technical field [0001] The invention relates to a sealing strip mounted on a flange at the periphery of an opening in a motor vehicle body. Background technique [0002] The body of the motor vehicle has openings, such as engine compartment openings, door openings, trunk openings, etc., and weather strips are arranged on flanges around the openings of the vehicle body. The weatherstrip forms a seal between the perimeter of the body opening and a corresponding component such as a door, hood, and the like. [0003] In the case where the weather strip is provided on the periphery of the opening of the vehicle body, the weather strip is provided such that the flange of the periphery of the opening of the vehicle body is inserted into a substantially U-shaped cross-sectional trim portion of the weather strip. [0004] For example, if image 3 As shown, at the front side of the motor vehicle, air enters the engine compartment of the motor vehicle from between the body 1 and the b...

AI Technical Summary

Problems solved by technology

However, the thickness of the side wall portion of the clipping portion 220 is constant and the clipping portion 220 is formed in a linear shape from the bottom wall side to the opening side, so that, due to the reaction force from the flange holding lips 225 and 227, the clipping portion 220 side wall The opening side end portions of the opening side are easily deformed in directions away from each other, and the force of the clamping portion 220 to grip the flange 7 is reduced, so that it is easy to separate the clamping portion 220 from the flange 7 in some cases.

[0014] When the weather strip 210 is provided in the corner of the opening of the vehicle body, since the weather strip 210 is bent, the holding lips 226 and the like are deformed inwardly (the side wall side of each lip), so that the weather strip 210 can be easily removed, which deteriorates the seal. performance, or the weather strip 210 (clamping portion 220) often collapses due to the swing of the interior retaining lips 226 and 227 and the body sealing lip 228 for water drainage
