ABSTRACT:
The arrangement shown and described herein is used to seal a closure structure of a vehicle body. A weatherstrip including metal strip inserts is extruded to include not only the usual hollow deflection bulb, but also a hollow flange sealing bulb, formed in a predetermined shape on the center portion of the side surface opposite the deflection bulb. When the retention portion of the weatherstrip around the metal strip inserts is crimped to form its operational "U" shaped recess, the flange sealing bulb is located at the bottom of the recess, substantially uniformly filling the space heretofor selectively filled with a bead of butyl mastic sealant. Once the thus formed weatherstrip is installed on a body closure flange or ledge, the edge of the flange or ledge depresses the hollow sealing bulb such that the latter effectively and uniformly seals off the inside of the flange or ledge from the outside thereof.
