A method of manufacturing a door glass run to be attached along an inner periphery of a door frame of a vehicle door. The method includes forming a door glass run having a main portion of a generally U-shaped cross-section, and seal lips which extend from ends of side walls of the main portion toward the inside thereof by extrusion such that one side wall has a height greater than that of the other side wall, forming first, second and third cutouts in the extruded door glass run from a bottom wall of the main portion to angular parts connecting the bottom wall to the side walls such that the first cutout faces about a center of a corner of the door frame, and the second and third cutouts face about borders between the corner of the door frame and straightly extending parts thereof, bending the door glass run having these cutouts in conformity with the corner of the door frame, and filling these cutouts with molding material to mold a bottom wall and angular parts connecting the bottom wall to side walls therein such that the thickness of the angular part connecting the bottom wall to the side wall having a greater height is increased, as compared to that of a corresponding angular part of the extruded glass run.

A door glass weather strip is structured such that a terminal end portion thereof to be contacted with a door pillar is cut away so as to correspond to the door pillar and is finish end formed. A clip to be inserted into a rectangular engaging hole formed in a door panel is provided on the surface of a mounting portion of the door glass weather strip. That particular, on the surface of the cut-away terminal end portion E of the mounting portion that is opposed to the outside surface of the door panel. The clip is formed of flexible synthetic resin, and includes a first engaging piece portion formed in a hook shape and engageable with the lower edge of the engaging hole in the door panel, and a second engaging piece portion which projects upwardly from the upper end of the first engaging piece portion and also includes in the top portion thereof an engaging stepped portion to be engageable with the upper edge of the engaging hole.

A weather strip includes a front portion, a rear portion and a transforming portion. A trim portion is attached to a drip channel of a vehicle door assembly, and a connecting web connects the trim portion to a tubular sealing portion. The connecting web has a width which gradually varies according to the part of the vehicle door assembly to which it is attached. The part of the tubular sealing portion attached to the drip channel from the rear roof line to the upper rear pillar of the door assembly is deformed, and a contacting portion thereof is fixed at an outside trim portion.

A sealing structure for sealing an inner side of a door glass in a door of an automobile includes a door trim having a downwardly extending trim flange facing toward the door glass; an inner door panel disposed adjacent the door trim with a clearance therebetween, the inner door panel having a downwardly extending panel flange facing the trim flange; an inner weather strip attached to the trim flange to form a seal between the door glass and the door trim; and an air sealing portion protruding from a lower edge of the inner weather strip. At least a part of the air sealing portion contacts the downwardly extending panel flange to shut-off or reduce air flow through the clearance.

A method of manufacturing a weatherstrip is provided which includes the step of connecting a first extruded component and a second extruded component, each having surface treated portions and cut to a predetermined length, by means of a molded connecting portion which is molded by forcing molding material into the cavity of a mold defined by inserting and setting the first and second extruded components in the mold. The step of molding the molded connecting portion is performed by forming separating slits in a third extruded component which is cut to a length shorter that the length of the molded connecting portion and has surface treated portions such that these separating slits extend along the surface treated portions from both ends to an intermediate section and by setting the thus prepared third extruded component in the mold such that the surface treated portions are in line with the surface treated portions of the first and second extruded components.

A door glass-run for automobiles is used in the fitted state to the frame of a car-door whose window opening is divided vertically by a division-bar such that a liftable-window and a quarter-window assembly are fitted to the window opening with the division-bar constructing part of the quarter-window assembly. The glass-run comprises a roof-side portion for holding the respective upper sides of the liftable-window and the quarter-window which includes a design lip disposed outside the car, and a division-bar portion branched from the roof-side portion. The roof-side portion is made of an integrally extruded component. The roof-side portion is notched at a branch section, from which the division-bar portion branches, to define a notched portion which includes at least the design lip. The notched portion is connected at its face on the side of the liftable window via a molded portion with a separate division bar portion. A slit of predetermined length is formed extending from the face on the side of the liftable window toward a root portion so that the division bar portion can be bent independently of the design lip.

Door glass run for automobiles

A weather strip to be attached along a door frame and a door west line of a vehicle has extruded weather strips extending along the door frame and the door west line, respectively, and an L-shaped molded corner member connecting ends of respective extruded weather strips. The extruded weather strip extending along the door west line is composed of an outer weather strip and an inner weather strip, each being provided with a flocked seal lip to come in sliding contact with respective surfaces of a window glass. The L-shaped molded corner member is composed of an outer corner portion and an inner corner portion, each having an extruded and flocked extension seal lip integrally formed with the flocked seal lip of each of the outer weather strip and the inner weather strip. The extruded and flocked extension seal lip is fitted in each of opposed surfaces of the outer corner portion and the inner corner portion of the L-shaped molded corner member.
