Benefits of technology

[0029] According to the means 8, the first fitting base portion is latched by the clip. Of the first fitting base portion, the part unaffected by incorporating the clip is formed of the solid material or the fine foaming material, whereby the operation/working-effect become effective. Further, the clip is relatively easily fitted as the part a...

Problems solved by technology

When the weather strip is thus configured, however, the difference in foaming rate between the main seal member and the sub-seal member and the difference in expansion rate therebetween may cause a warp to be produced in the weat...

Embodiment Construction

[0034] An embodiment of the invention will now be described by reference to the drawings.

[0035] Automobiles are provided with open-and-close front doors and a weather strip 1 is installed along the outer periphery of such a front door as shown in FIG. 2. The greater part of the weather strip 1 along the longer direction is formed by an extrusion molding portion 2. Moreover, corner portions (with point patterns in FIG. 2) are formed with die-molded sections 3.

[0036] As a portion corresponding to the roof side portion (upper side portion of FIG. 2) out of the extrusion-molded portion 2 has a distinctive feature according to the embodiment of the invention, the construction of the portion in question will be described as follows.

[0037] As shown in FIG. 1, the extrusion-molded portion 2 in the upper side portion has a main seal member 11 as a first seal member, a sub-seal member 21 as a second seal member and a coupling portion 31 for coupling both the seal members 11 and 21.

Abstract

An extrusion-molded portion in the upper side portion of a weather strip is provided with a main seal member, a sub-seal member and a coupling portion. The main seal member has a first fitting base portion in the form of a substantially flat plate fitted to the first retainer of a door frame, and a hollow seal portion formed integrally with the first fitting base portion. The sub-seal member has a second fitting base portion in the form of a substantially flat plate fitted to a second retainer, and a seal lip. The seal lip, the coupling portion and the hollow seal portion are consecutively formed by monolithic molding with EPDM sponge rubber. The greater part of the second fitting base portion and the central part of the first fitting base portion are formed of EPDM solid rubber. Therefore, the difference in expansion rate hardly occurs and a warp is restrained from being generated.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a weather strip applied to the joints of an automobile door or a roof side, for example. [0003] 2. Related Art [0004] Weather strips are installed around the outer peripheral edges of automobile doors and the like. Heretofore, a weather strip having a hollow seal portion (main seal portion) and a weather strip having a seal lip (sub-seal portion) maybe applied to respective parts corresponding to the upper side of a door. In this case, these two pieces of weather strips have to be produced separately from each other and installed independently of each other. [0005] On the other hand, the art of integrating a main seal member having the main seal portion with a sub-seal member having the sub-seal portion by means of a coupling portion has been proposed (see Japanese Patent Publication No. JP-A-2002-307952, for example). With this arrangement, the number of man-hours necessary for the ...
