Provided is a door weather strip that provides excellent closing performance of a door and sound insulation properties, and does not impair the appearance. A door weather strip includes a mounting base and a hollow seal portion. The mounting base has a hole penetrating the mounting base, and the hole is mounted with a valve penetrating the mounting base. At the time of manufacturing a vehicle, the door is closed with the valve open, so that the air within the hollow seal portion is discharged to compress and shape the hollow seal portion (first step). When the door is opened, the valve is closed to retain the shaped state of the hollow seal portion (second step). The valve is opened again at a time point when the hollow seal portion begins to come into contact between the door and the vehicle body opening while the door is closing, or at a time point when the door is closed (third step).

A door weather strip includes at least an exterior installation base member installed on a door frame or a door molding, and a seal lip that is formed protruding and extending above and outside in a vehicle width direction from the exterior installation base member and elastically comes into contact with a vehicle body opening peripheral edge when a door is closed, in which a hard portion that is harder than a seal lip main body portion constituting the seal lip is formed between a tip of the seal lip and a root portion between the seal lip and the exterior installation base member and on the vehicle body opening peripheral edge side.

A bonding sheet material for a weather strip disclosed herein is a composition including at least EPDM, a cross-linking agent, and carbon black, and has a volume resistivity of 1.0 × 10.sup.6 Ω.Math.cm or more based on a double ring electrode method of JIS-K6271-1: 2015 where a test piece has a thickness of 2 mm. When the composition is placed in a mold and molded to press the composition at 50° C. under 100 Kgf/cm.sup.2 for 60 seconds whereby a molded article is produced, the molded article has a thickness change rate of 100% or less, the thickness change rate being represented by formula (1): Thickness change rate = ((thickness of molded article after 30 minutes from releasing press - thickness of mold)/thickness of mold) × 100.

A sunroof panel for a vehicle includes a mounting surface at which a first roof element is mounted, a first frame including a first plate that includes a first mounting surface, the first frame including a first stepped plate that extends from a longitudinal end portion of the first plate to generate a step relative to the first plate, a second frame including a second plate that includes a second mounting surface, a joining portion joining the first frame and the second frame in a state where the first stepped plate and an end portion of the second plate overlap each other to cause the first mounting surface and the second mounting surface to be coplanar with each other, and a film attached to the first mounting surface and the second mounting surface to cover a gap formed between the first plate and the second plate.

A process is for manufacturing a complex motor vehicle glazing including a glass pane, an elastomer seal and a metal insert overmolded by the elastomer seal. The process includes inserting an edge of a glass pane and a metal insert into an encapsulation mold forming a leaktight cavity around the edge of the glass pane, filling the leaktight cavity containing the edge of the glass pane and the metal insert, by injecting an encapsulation composition including a polypropylene (PP)/thermoplastic elastomer (TPE) compound in the molten state, cooling the encapsulation composition to form an elastomer seal in which the metal insert is integrated, and releasing the elastomer seal from the mold. The PP/TPE compound includes from 30% to 80% by weight of polypropylene (PP) and the metal insert is covered over its entire surface liable to come into contact with the encapsulation composition, with a polypropylene coating.

A sealing element including a cover strip, in particular for sealing a window pane at the inlet of a window channel into which the window pane can be retracted. A portion of the sealing element, which portion is to be produced by injection molding, is connected to the cover strip by being molded onto the cover strip. In a corresponding method, the cover strip is preheated such that its shrinkage is matched to the shrinkage of the molded-on material, until the cover strip has cooled down to approximately the ambient temperature.
