Problems solved by technology

[0005] However, since the moving position of the door glass changes when the door glass is pushed inward by air pressure, etc., in the case where only the inner and outer sealing lips play a sealing role, there is a risk that the sealing effect will decrease

Embodiment Construction

[0061] Embodiments of the present invention are described below with reference to the drawings.

[0062] As shown in Figure 1, the motor vehicle door (the front door in the figure: hereinafter referred to as the door) is arranged as a door at the opening of the body of the vehicle body to be opened and closed, and the door includes a door glass G suitable for lifting, And a glass run channel 2 made of ethylene-propylene-diene terpolymer (EPDM), the glass run channel 2 conforms to the outer peripheral shape of the door glass G.

[0063] Viewed from its longitudinal direction, the glass run channel 2 is provided with: an extrusion part 3, corresponding to the upper part of the glass run channel 2; part; and molded parts 6, 7 (parts indicated by a scatter pattern in the figure), connecting the ends of the respective extruded parts 3, 4, 5 to each other. Each extruded portion 3 to 5 is formed substantially linearly by an extruder not shown. In addition, the molded parts 6, 7 are...

Abstract

A glass run is assembled to an automobile door having a door glass. The glass run includes a first base portion adapted to be fitted in a sash, a facing wall part provided so as to substantially face an exterior side surface of a guide member, the exterior wall part provided substantially in parallel with an exterior side surface of the guide member, an exterior seal lip which seals the exterior side surface of the guide member, a restricting wall part which restricts a projecting portion, a mount wall part adapted to be mounted on an interior member, an interior seal lip which seals an interior side of the guide rail, an exterior sub-seal lip and an interior sub-seal lip which are provided between the exterior seal lip and the interior seal lip.

Description

technical field [0001] The invention relates to a glass run channel installed on a vehicle door. Background technique [0002] Generally, a glass run channel is provided, for example, on a door of a motor vehicle for sealing the periphery of a moving door glass. The glass run channel has a main body with a substantially U-shaped cross-section, and a pair of sealing lips protruding from the ends of the two side walls of the main body into the main body. The main body is engaged with a window frame provided on the vehicle door. In this way, along the periphery of the door glass, the inside surface and the outside surface of the door glass are sealed in the manner of a sealing lip. [0003] In addition, in recent years, in order to reduce wind noise when the vehicle is running at high speed and to improve the appearance quality, a technology that can make the outer surface of the door flush with the outer surface of the door glass (flush surface) is required. [0004] Based ...
