A glass run having a general portion formed by extrusion molding and a mold-forming portion that connects terminals of the general portion attached to a corner portion of a door frame has a substantially U-shaped cross section including a vehicle exterior side wall, a vehicle interior side wall, and a bottom wall joining the vehicle exterior side wall and the vehicle interior side wall; and has a vehicle exterior side seal lip and a vehicle interior side seal lip that obliquely protrude in an inner direction of an opening having the substantially U-shaped cross section from the vehicle exterior side wall and the vehicle interior side wall, respectively, and the vehicle exterior side seal lip of the mold-forming portion is formed with a seal lip extension portion having a seal lip length extended as compared to the vehicle exterior side seal lip formed in the general portion.

A continuous sealing flat for a truck cargo box for a unibody motor vehicle includes a pair of parallel opposed top side rails and a cab back panel disposed between and orthogonally thereto. A central portion of the cab back panel has a central ledge having a substantially flat upper surface extending horizontally between each of the pair of parallel opposed top side rails. A pair of corner members is disposed over and proximate a forward end of each of the parallel opposed top side rails. A forward end of a horizontal portion of each of the pair of corner members comprises a flat upper surface proximate to and at substantially the same vertical height as a vertical height of the flat upper surface of the central ledge to form a substantially continuous corner flat upper surface.

Disclosed is a structure in which no gap that allows water entry between a weather strip and a glass run is formed in a situation where the weather strip at an upper frame portion of a window frame extends gradually downwardly apart from the glass run. An upper glass run portion is provided with a door panel sealing lip. The door panel sealing lip is provided with a gradually varying portion such that a downward protruding length of the door panel sealing lip increases. The gradually varying portion is disposed so as to contact an outer sealing lip of the weather strip.

Sealing performance is improved without deteriorating appearance. A pillar P side of a roof-side seal lip 34 and a roof R side of a pillar-side seal lip 43 are spaced apart from each other in a transverse direction of a vehicle when a door 110 is open. The pillar P side of the roof-side seal lip 34 is formed so as to be closer to the roof R side of the pillar-side seal lip 43 toward an end of the pillar P side. When the door 110 is closed, the roof-side seal lip 34 comes into contact with the pillar-side seal lip 43.

In a method of manufacturing a seal assembly, strips of material are extruded to form first and second bodies, and ends of the bodies are positioned into a mold cavity of a molding apparatus. An elastomeric material is injected into the mold cavity to form a locator device having a foot portion and a tab portion with the tab portion defining a first reference point. A thermoplastic elastomeric material is injected into the mold cavity to form a corner mold covering the body ends and the foot portion of the locator device with the corner mold defining a second reference point. The corner mold bonds the first body end, the second body end, and the locator device together to fix the locator device to the first body end at a locator position such that a predetermined distance between the reference points is maintained during injecting of the thermoplastic elastomeric material.

A weather strip made of an elastic material includes an insert member having a plurality of through holes which is embedded in a corner portion of the weather strip. In the corner portion, a clip insertion hole in which a clip for attaching the corner portion to the automobile body is insertable is formed, and in the insert member, a clip hole is formed in a position corresponding to the clip insertion hole. In the outer peripheral portion of the clip hole, an additional hole communicating with the clip hole is formed, and the elastic materials of which the corner portion is made and that are situated on the obverse and reverse sides of the insert member are united together through the additional hole.

A seal arrangement for sealing a corner region of a window against a vehicle body component of a motor vehicle. The seal arrangement defines a seal plane, a first seal axis and a second seal axis which extends transversely with respect to the latter. A fastening section serves for fastening to the vehicle body component. A seal section has a sealing lip which can be deflected elastically transversely with respect to the seal plane when the corner region of the window comes into contact with the sealing lip, and which extends arcuately from the first seal axis to the second seal axis. The sealing lip is configured as a molded sealing lip over its entire arcuate extent.
