ABSTRACT:
An elongated weatherstripping for use with a hingedly mounted closure member such as an entrance door includes a body of flexible material having an inside surface adapted to be secured to a stop element facing an edge portion of the door. The body includes an edge portion projecting laterally outwardly along one edge of the stop element and a deflectable sealing element integrally formed with the body and pivotally joined along an outer edge of the laterally projecting portion in a reverse turn. The sealing element includes an outwardly facing sealing surface which is adapted to seal against the side face of the door when the door is in a closed position. The sealing surface is concave/convex outwardly from the reverse turn toward the closure member with an S-shaped cross-section. The convex portion is deflectable inwardly toward the body upon pivotal movement at the reverse turn resulting from inward contact and sliding lateral contact with the door as it is closed.
