Weather strip

Abstract

The invention provides a weather strip. The weather strip is installed on a door of an automobile, e.g., an opening edge of a back door arranged on the back of the automobile, so as to prevent a following condition that in order to improve beauty, automobile window glass is arranged to be nearer the outer side of the automobile than a window frame, so water penetrate through the automobile window glass and then reach the automobile inner side due to a failure to seal the space between the automobile window glass and the window frame in the prior art. The weather strip is provided with a tongue-shaped seal lip which is in elastic contact with an automobile body. An extension part and the tongue-shaped seal lip form a largely V-shaped groove part. The whole outer side face of the seal lip is largely in shape of an oval. A first hollow part with a largely oval-shaped side face is formed in the length direction in a through manner. The side face of the tongue-shaped seal lip is largely in the shape of an L, extends from the seal lip and is connected together. A third seal lip extends from a base body part. A second hollow part with a largely quadrangle-shaped side face is perforated between the seal lip and the base body part. Mountain-shaped keeping lips are arranged along the upper part and lower part or left part and right part of a base face of the base body part.

Description

technical field [0001] The present invention relates to a weather strip that is attached to a door of an automobile, for example, the opening edge of a rear door provided on the back of the automobile, so that rainwater, etc., can properly flow out of the automobile without leaking into the interior of the automobile. , and this weather stripping is firmly installed on the window frame of the car door, etc. Background technique [0002] As an example of prior art showing such a weather strip, there is a technique disclosed in Japanese Patent Application Laid-Open No. 2009-166565. [0003] If this is stated as Figure 5 As shown in (a) and (b), the installation structure of the door weather strip 1 is a structure installed along the outer peripheral portion of the window frame 3 of the door 2 of the automobile, and the door weather strip 1 and the door weather strip are installed. The window frame 3 of the strip 1 is characteristic. That is, as from Figure 5 The cross-sect...

Problems solved by technology

[0010] That is, next, according to an example of the above-mentioned prior art, it is a technique in which the window frame cover 7 extended from the mounting base 4 covers the vehicle outer side of the exterior portion 9 from one end portion 11 of the exterior portion 9 and is drawn into the exterior surface. The other end portion 12 of the portion 9, thus, the installation and positioning of the door weather stripping 1 are carried out, so there are the following problems: the installation base 4 is extremely complicated, and the window frame cover 7 is required in addition, on this basis, the window frame The structure of the base part 8 of 3 presents an abnormal shape, and the man-hours for body design and the amount of processing materials increase
